Directory of Open Access Journals Sweden. Morrisssey Text Available Calophyllum brasiliense is present in a wide natural distribution range in Brazil and its monopodial growth, with a rectilinear stem and a moderately dense timber has attracted the attention from the logging industry in recent morriissey. In the meantime, the lack of efficient rescue and vegetative propagation methods of adult plants has been a narrowing condition for the selection of superior genotypes in breeding programs of the species.
Therefore, we evaluate epicormic shoots induction methods and the rooting cuttings of 14 year-old Morrisssey brasiliense trees. From this scope, three methods of epicormic shoots induction were evaluated: coppicing, girdling and partial girdling. Results have indicated the feasibility of Calophyllum brasiliense vegetative rescue by cuttings method using epicormic shoots induced by coppicing and girdling.
In contrast, partial girdling was not effective in epicormic shoots emission. Concerning adventitious roots, the sprouting technique had no influence in the rooting of cuttings, showing variation among the different stock plants.

Full Text Available Abstract Exercise is a double-edged sword: when practiced in moderation, it increases the expression of antioxidant enzymes, but when practiced strenuously it causes oxidative stress and cell damage.
In this context, polymorphisms in the interleukin IL-6 gene should be investigated better because they can influence performance, at least in exercise that generates oxidative stress and leads to muscular injuries with consequent inflammation.
The IL-6 genotypes were associated with significant differences in lipid peroxidation, with the CC mutant having lower values. There were also significant differences among these genotypes in the response to supplementation with pequi oil, exercise-induced damage and C-reactive protein CRP levels.
The best protection against damage was observed with the heterozygous genotype. Although the CC genotype showed an increase in CRP levels after supplementation, the lack of a positive correlation between triglycerides and high-sensitivity CRP in this mutant genotype after supplementation indicated a protective effect of pequi.
These findings deserve further investigation, particularly with regard to the quantification of circulating IL-6 concentrations.
Differential effects of land use on ant and herbivore insect communities associated with Caryocar brasiliense Caryocaraceae. Full Text Available Simplification of natural habitats leads to a modification of the community associated with a host plant.
Pequi trees Caryocar brasiliense are common to find in central Brazil, especially in the middle of monocultures, such as soy, corn, pasturelands or Eucalyptus plantations.
On this scenario we hypothesized that habitat modification differentially affects the diversity of ants and herbivore insects associated with this species. The aim of the work was to test if C. Ants and herbivore insects were collected monthly during using beating technique. The results showed that ant species richness was higher in pequi trees located in preserved Cerrado, followed by trees in pastureland and Eucalyptus plantation, respectively.
The ant abundance was lower in the Eucalyptus plantation but no difference in ant abundance was observed between trees in pastureland and the preserved Cerrado. Moreover, herbivore insects exhibited lower number of species and individuals in trees located in the preserved Cerrado than in the pastureland and Eucalyptus plantation. We concluded that habitats simplified by human activities may result in diversity loss and may change species interactions.

Genome-wide identification of potato long intergenic noncoding RNAs responsive to Pectobacterium carotovorum subspecies brasiliense infection.
While much progress has been made in determining the biological functions of lncRNAs in mammals, the functional roles of lncRNAs in plants are still poorly understood. Specifically, the roles of long intergenic nocoding RNAs lincRNAs in plant defence responses are yet to be fully explored. The lincRNAs are expressed from all 12 potato chromosomes and generally smaller in size compared to protein-coding genes.
Like in other plants, most potato lincRNAs possess single exons. A time-course RNA-seq analysis between a tolerant and a susceptible potato cultivar showed that lincRNAs are responsive to Pectobacterium carotovorum subsp. Moreover, coexpression analysis revealed that 17 of these lincRNAs are highly associated with 12 potato defence-related genes.
Together, these results suggest that lincRNAs have potential functional roles in potato defence responses. Furthermore, this work provides the first library of potato lincRNAs and a set of novel lincRNAs implicated in potato defences against P.
Optimization of performance, emission, friction and wear characteristics of palm and Calophyllum inophyllum biodiesel blends. Mosarof, M. Biodiesel is an alternative diesel fuel that is produced from renewable resources. Energy studies conducted over the last two decades focused on solutions to problems of rising fossil fuel price, increasing dependency on foreign energy sources, and worsening environmental concerns.

Production of palm and Calophyllum inophyllum based biodiesel and investigation of blend performance and exhaust emission in an unmodified diesel engine at high idling conditions.
Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in many countries of the world production and use of biodiesel has gained popularity. In this research, biodiesel from palm and Calophyllum inophyllum oil has been produced using the trans-esterification process.
Properties of the produced biodiesels were compared with the ASTM D standard: biodiesel standard and testing methods. Density, kinematic viscosity, flash point, cloud point, pour point and calorific value, these are the six main physicochemical properties that were investigated.
Both palm biodiesel and Calophyllum biodiesel were within the standard limits, so they both can be used as the alternative of diesel fuel. Furthermore, engine performance and emission parameters of a diesel engine run by both palm biodiesel—diesel and Calophyllum biodiesel—diesel blends were evaluated at high idling conditions. Brake specific fuel consumption increased for both the biodiesel—diesel blends compared to pure diesel fuel; however, at highest idling condition, this increase was almost negligible.
Exhaust gas temperatures decreased as blend percentages increased for both the biodiesel—diesel blends. For low blend percentages increase in NO. Experimental investigation of performance and regulated emissions of a diesel engine with Calophyllum inophyllum biodiesel blends accompanied by oxidation inhibitors.
It is expected that antioxidants may affect the clean burning characteristic of biodiesel. Calophyllum inophyllum Linn oil is one of the promising non-edible based feedstock which consists of mostly unsaturated fatty acids.
This paper presents an experimental investigation of the antioxidant addition effect on engine performance and emission characteristics. The addition of antioxidants increased oxidation stability without causing any significant negative effect of physicochemical properties.

Engine performance and emissions using Jatropha curcas, Ceiba pentandra and Calophyllum inophyllum biodiesel in a CI diesel engine. Biodiesel is a recognized replacement for diesel fuel in compressed ignition engines due to its significant environmental benefits.
The purpose of this study is to investigate the engine performance and emissions produced from Jatropha curcas, Ceiba pentandra and Calophyllum inophyllum biodiesel in compressed ignition engine. The biodiesel production process and properties are discussed and a comparison of the three biodiesels as well as diesel fuel is undertaken.
The engine performance shows that those biodiesel blends are suitable for use in diesel engines. Biodiesel blends have also shown a significant reduction in CO 2 , CO and smoke opacity with a slight increase in NO x emissions. Use of calophyllum inophyllum biofuel blended with diesel in DI diesel engine modified with nozzle holes and its size. Improved thermal efficiency, reduction in fuel consumption and pollutant emissions from biodiesel fueled diesel engines are important issues in engine research.
To achieve these, fast and perfect air-biodiesel mixing are the most important requirements. The mixing quality of biodiesel spray with air can be improved by better design of the injection system.

Full Text Available In recent years, the beauty leaf plant Calophyllum Inophyllum is being considered as a potential 2nd generation biodiesel source due to high seed oil content, high fruit production rate, simple cultivation and ability to grow in a wide range of climate conditions.
However, however, due to the high free fatty acid FFA content in this oil, the potential of this biodiesel feedstock is still unrealized, and little research has been undertaken on it.
In this study, transesterification of beauty leaf oil to produce biodiesel has been investigated. A two-step biodiesel conversion method consisting of acid catalysed pre-esterification and alkali catalysed transesterification has been utilized. The three main factors that drive the biodiesel fatty acid methyl ester FAME conversion from vegetable oil triglycerides were studied using response surface methodology RSM based on a Box-Behnken experimental design.
The factors considered in this study were catalyst concentration, methanol to oil molar ratio and reaction temperature. Linear and full quadratic regression models were developed to predict FFA and FAME concentration and to optimize the reaction conditions. The significance of these factors and their interaction in both stages was determined using analysis of variance ANOVA.
In the alkali catalysed transesterification process 7. The good agreement between model outputs and experimental results demonstrated that this methodology may be useful for industrial process optimization for biodiesel production from beauty leaf oil and possibly other industrial processes as well.

Project in determination of crystal structure of nitrogen fixation proteins from azospirilum brasiliense and herbaspirilum seropedicae by synchrotron x-ray diffraction. Barbosa, Valma M. Full text.
Biological nitrogen fixation is essential for maintaining the nitrogen cycle on earth and of high importance for Brazilian agriculture. The nitrogenase enzyme system, which provides the biochemical machinery for nitrogen fixation, consists of two component metalloproteins, the molybdenumiron Mo Fe protein and the iron Fe protein. Nitrogen fixation is a very energy-intensive process, requiring around 16 moles of ATP for each mol of N 2 fixed reduced.
As a consequence, synthesis and activity of nitrogenase is tighty regulated at two levels: general and specific. The general level regulation is mediated by the ntr nitrogen regulation system. Two gene products are involved: the ntrB gene product NtrB is responsible for the activation of the ntrC gene product NtrC by phosphorylating a conserved Asp54, which activates the expression of the nifA gene. The aim of this project is to solve the crystal structure of dinitrogenase reductase iron protein and dinitrogenase molybdenum-iron protein from Azospirilim brasiliense and the regulatory proteins NifA from Herbaspirillum seropedicae and NtrC Azospirillum brasiliense.
The three dimensional structure of the proteins involved in this project will allow a better understanding of the mechanism of biological nitrogen fixation.
To this end, the data collection will probably be done at the LNLS facilities which will be available in the near future.

The highly unbalanced nature of bio-oil composition poses a serious threat in terms of storage and utilization of bio-oil as a viable fuel in engines. So it becomes inevitable to study the variations in physicochemical properties of the bio-oil during storage to value its chemical instability, for designing stabilization methodologies.
The present study aims to investigate the effects of storage stability of bio-oil extracted from pyrolyzing Calophyllum inophyllum CI deoiled seed cake on the engine operating characteristics. Gas chromatography-mass spectrometry was employed to analytically characterize the unaged and aged bio-oil samples.
Engine testing of the bio-oil sample revealed that aged bio-oil samples deteriorated engine performance and increased emission levels at the exhaust. The oxidatively aged sample showed the lowest BTE The direction of the emulsions was evaluated by dilution method and by macroscopic analysis, the appearance, homogeneity and organoleptic properties were evaluated. To evaluate the accelerated stability, the samples were stored at different stress conditions and evaluated the pH value, macroscopic analysis and rheological.

Analytical characterization of products obtained from slow pyrolysis of Calophyllum inophyllum seed cake: study on performance and emission characteristics of direct injection diesel engine fuelled with bio-oil blends.
This paper aims to analyse the characteristics and properties of the fractions obtained from slow pyrolysis of non-edible seed cake of Calophyllum inophyllum CI.
Owing to the high volatile content of CI biomass GC-MS and FT-IR analysis of bio-oil showed the presence of higher amount of oxygenated compounds, phenol derivatives, esters, acid and furans. The physicochemical properties of the bio-oil were tested as per ASTM norms which imply that bio-oil is a highly viscous liquid with lower heating value as compared to that of diesel fuel. The chemical composition of evolved gas was analysed by using GC testing which revealed the presence of combustible components.
The FT-IR characterization of biochar showed the presence of aliphatic and aromatic hydrocarbons whereas the elevated amount of carbon in biochar indicates its potential to be used as solid fuel. The performance and emission characteristics of CI engine were assessed with different CI bio-oil blends and compared with baseline diesel fuel. The results showed that addition of bio-oil leads to decreased brake thermal efficiency and increased brake specific energy consumption.
Meanwhile, increase in blend ratio reduces harmful pollutants such as oxides of nitrogen and smoke in the exhaust.

Effect of temperature and the light on germination of Nicotiana longiflora Cavaniles and Oenothera indecora Camb. Con temperaturas alternadas, N.
A partir de la temperatura base se puede inferir que N. Nicotiana longiflora and Oenothera indecora are species of recent appearance in croplands in the Argentine humid pampa zone and there is a lack of knowledge about the environmental factors affecting their germination.
The temperature and light requirements for germination and the base temperature of both species were determined. All plant growth regulator PGR treatments induced direct adventitious bud formation from the genotypes. Although most of the TDZ-treated inflorescences produced buds, these buds failed to elongate into shoots. Buds on explants treated with BAP elongated into shoots that were easily rooted in vitro and further established in potting mix in high humidity.
The PGR treatments significantly affected shoot regeneration frequency P Gamma radiation effect on Populus nigra assimilatory pigments.
The influence of low intensity gamma radiation on the photosynthesis in young poplar saplings was studied. Black poplar Populus nigra was chosen due to its ecological importance, as fast growing tree species with many hybrids, in the frame of a polluted environment. Assimilatory pigments in the leaves of irradiated saplings were assayed using standard spectrophotometric method in acetone extract. Series of five saplings formed the experimental samples.
Chlorophyll a and chlorophyll b levels appeared as diminished in exposed samples in comparison to the controls.
Linear regression was established in every case, the line slope showing the higher effect in chlorophyll b. Carotene pigments presented a slight increasing tendency in the exposed samples.
Assimilatory pigment sum was shown to be affected by the same decreasing tendency. Student t-test was applied two tailed, pair type to reveal statistical significance of observed modifications. Though not very deep, the modifications induced by exposure to gamma radiation of low intensity comparable to the local atmospheric variations, caused by both natural and artificial sources represent putative inhibitory factors in young plant photosynthesis. The main mechanism of radiation action seems to be water radiolysis, triggering peroxide cascade, generally producing toxic products for the cell metabolism.
Nevertheless, living cell ability to repair some damages caused by external stress could be revealed in the present case by the enhancing tendency of the carotenes which sustain photosynthesis as secondary pigments.
Substantia nigra depigmentation and exposure to encephalitis lethargica. Parkinsonism has occasionally been reported as a consequence of infectious diseases. The present study examines the clinical and pathological correlates of parkinsonism across birth cohorts in relation to critical exposure to the encephalitis lethargica epidemic in the early s.
The study population consisted of participants in the Nun Study, of whom died and came to autopsy. Qualitative indices of substantia nigra SN depigmentation were verified in a subset of 40 randomly selected subjects using quantitative stereological techniques.
SN depigmentation, detected neuropathologically, was correlated with clinical parameters of Parkinson disease, age, and birth cohort.
SN depigmentation was detected in 57 Quantitative measures of SN depigmentation were increased in this birth cohort compared to age matched subjects from flanking birth cohorts and p Intrinsic and integrative properties of substantia nigra pars reticulata neurons.
The GABA projection neurons of the substantia nigra pars reticulata SNr are output neurons for the basal ganglia and thus critical for movement control. Their most striking neurophysiological feature is sustained, spontaneous high frequency spike firing. A fundamental question is: what are the key ion channels supporting the remarkable firing capability in these neurons?
Recent studies indicate that these neurons express tonically active TRPC3 channels that conduct a Na-dependent inward current even at hyperpolarized membrane potentials. SNr GABA neurons have a higher density of INaT , contributing to the faster rise and larger amplitude of action potentials, compared with the slow-spiking dopamine neurons.
In SNr GABA neurons, the rising phase of the action potential triggers the activation of high-threshold, inactivation-resistant Kv3-like channels that can rapidly repolarize the membrane. These intrinsic ion channels provide SNr GABA neurons with the ability to fire spontaneous and sustained high frequency spikes. Thus, afferent GABA and glutamate synaptic inputs sculpt the tonic high frequency firing of SNr GABA neurons and the consequent inhibition of their targets into an integrated motor control signal that is further fine-tuned by neuromodulators.
Mycorrhization of containerised Pinus nigra seedlings with Suillus granulatus under open field conditions. Seedling mycorrhization acts as an efficient tool for improving the quality of seedlings. In this study, the effectiveness of Suillus granulatus, originating from Pinus heldreichii forests Montenegro , to produce containerized ectomycorrhizal seedlings of autochthonous Pinus nigra in open field conditions was investigated.
Spore , , and vegetative , , inoculation on ectomycorrhizal formation and seedling growth were tested. Spore and vegetative inoculums of autochthonous Pisolithus arhizus were used in the same trial as additional control treatments.
The utilization of vegetative and spore inoculums of autochthonous S. Mycelial inoculations resulted in slightly developed S. Therefore, it would be feasible to use spore inocula of S. Controlled mycorrhizal inoculation of seedlings is not a common practice in Montenegrin and Serbian nurseries; as such, the obtained results will contribute to the enhancement of nursery production of Pinus nigra and other conifers.
This also could be assumed as a starting point for many further efforts and investigations with autochthonous fungal and plant material in this region. Author 47 refs. The structural characteristics of the substantia nigra were studied microscopically and quantified using computer morphometric methods at brain autopsies of individuals with Parkinson's disease who had died from intercurrent diseases and those who had no evidence of neurological disorders in their history a control group.
This investigation could clarify the features of morphochemical changes in both the neural network structures and the glial populations of the substantia nigra in Parkinson's disease.
The number of neurons containing tyrosine hydroxylase a marker of dopamine neurons in the compact part of the substantia nigra a ventral region was smaller and the density distribution of Lewy bodies was higher in the patients with Parkinson's disease than in the control group.
The accumulation of iron II compounds in the cellular elements and neuropile and the increased expression of glial fibrillary acidic protein in Parkinson's disease were more pronounced than those in the controls. Postmortem diagnosis in Parkinson's disease should be based on a full description of a set of neuronal and glial morphochemical and structural changes in the substantia nigra rather than on the identification of cellular markers for the neurodegenerative process.
Infusion of opiates into substantia nigra protects against maximal electroshock seizures in rats. Microinfusion of morphine sulfate 50 nmol , [d-Ala2]-Met-enkephalin 35 nmol or dynorphin A 1 nmol bilaterally into the substantia nigra significantly attenuated seizures induced by maximal electroshock in rats. This action was accompanied by stereotyped behavioral hyperactivity.
These anticonvulsant and behavioral effects were antagonized by systemic naloxone administration; neither effect was observed after intranigral microinjection of dynorphin A amide 1 nmol.
These results are consistent with a mu opiate receptor-mediated inhibition of substantia nigra efferent neurons, and with the proposal that bilateral inhibition of nigral efferents attenuates seizure propagation. However, intranigral morphine failed to alter the severity of i.

Black walnut Juglans nigra L. Vegetative and in vitro black walnut propagation techniques, however, are variable and highly genotype dependent. Optimizing plant growth regulator type and Eight patients, aged years, with idiopathic Parkinson disease were studied to determine whether the characteristic degeneration of the substantia nigra zona compacta , seen pathologically, could be identified in vivo on T2-weighted proton MR imaging 1.
The mean width of the substantia nigra in the eight patients was 4. These changes on MR imaging are probably due to atrophy of the zona compacta of the substantia nigra , but excess iron in the zona reticulata may partially contribute to these findings. MR imaging may be useful for differentiating ''classic'' Parkinson disease from other extrapyramidal degenerative disorders and for predicting response to drug therapy.

Then, the Stimulation of the substantia nigra influences the specification of memory-guided saccades.
In the absence of sensory information, we rely on past experience or memories to guide our actions. Because previous experimental and clinical reports implicate basal ganglia nuclei in the generation of movement in the absence of sensory stimuli, we ask here whether one output nucleus of the basal ganglia, the substantia nigra pars reticulata nigra , influences the specification of an eye movement in the absence of sensory information to guide the movement.
We manipulated the level of activity of neurons in the nigra by introducing electrical stimulation to the nigra at different time intervals while monkeys made saccades to different locations in two conditions: one in which the target location remained visible and a second in which the target location appeared only briefly, requiring information stored in memory to specify the movement.
Electrical manipulation of the nigra occurring during the delay period of the task, when information about the target was maintained in memory, altered the direction and the occurrence of subsequent saccades.
Stimulation during other intervals of the memory task or during the delay period of the visually guided saccade task had less effect on eye movements. When the visual stimulus was present, stimulation of the nigra resulted in no significant rotation and decreased the reaction time of contralaterally directed saccades slightly. Based on these measurements, stimulation during the delay period of the memory-guided saccade task influenced the metrics of saccades much more than did stimulation during the same period of the visually guided saccade task.

Reproductive biology and food habits of Pseudoboa nigra Serpentes: Dipsadidae from the Brazilian cerrado. Full Text Available Herein we provide data on body size, sexual size dimorphism,reproductive cycle, and food habits of the pseudoboini snake Pseudoboa nigra , which is distributed mainly in central South America throughout the Cerrado domain.
Based on dissections of preserved specimens, it is shown that females attain, and mature at,larger body sizes than males. There is no significant sexual dimorphism in head length, but males have longer tails relative to their body sizes. Vitellogenesis, egg-laying, and sperm production occur throughout the year, but males do not exhibit long-term sperm storage.
The main prey of P. Electrophysiological localization of distinct calcium potentials at selective somatodendritic sites in the substantia nigra. In one class of neurons, which discharge in a "phasic" fashion and are located The dendrites of dopaminergic neurons in the substantia nigra play a pivotal role in the neurochemical homeostasis of the nucleus. It is conceivable therefore that the cell body and dendrites of these nigral neurons possess distinct and independent electro-responsive features.
By means The differential localization of these calcium conductances in sub-populations of neurons is likely to determine the functions for the calcium responses in each type of neuron, and moreover highlight the dendrites as dynamic Although the etiology of PD is unknown, but major biochemical processes such as oxidative stress is largely described. Morus nigra L. Muscle stiffness and apomorphine test were assessed in 6 rats of any groups after two weeks.
Protein oxidation, lipid peroxidation and ACE activity were assessed in brains of 6 rats of each group after 24 hours. Protein oxidation in Morus nigra group was significantly lower than neurotoxin group.
Brain ACE activity in neurotoxin, captopril and Morus nigra groups were inhibited. Conclusion: Morus nigra L. Conclusions: We present a histologically validated anatomical description of the substantia nigra on high field spin-echo high resolution magnetic resonance images and were able to delineate all five nigrosomes. In accordance with the pathological literature we did not observe changes in the nigrosome structure as manifest by volume or signal characteristics within the substantia nigra in Parkinson's disease whereas in progressive supranuclear palsy there was microarchitectural destruction.
The development of hyperhydric tissue on the stems of Sambucus nigra L. Full Text Available Hyperhydric intumescences on the stems of Sambucus nigra arise in places where the stem lenticels are immersed in water. The hyperhydric tissue develops through the transformation of the multilayered phelloderm, the parenchyma of the cortex.
The phellogen loses its meristematic properties and is either incorporated into the developing hyperhydric tissue or crushed. The succesive stages of hyperhydric changes which depend on the intense growth of cells and on the ability to devide acquired by them are presented. The stability of rutin and chlorogenic acid during the processing of black elder Sambucus nigra inflorescence.
To enhance the bleaching efficiency, the activator of tetra acetyl ethylene diamine TAED was used in conventional H2O2 bleaching. In this research, the process with hydrogen peroxide activated by TAED bleaching of Populus nigra chemi-thermo mechanical pulp was optimized.
Suitable bleaching conditions were confirmed as follows: pulp con Antiproliferative and apoptotic effect of Morus nigra extract on human prostate cancer cells. Numerous studies have investigated the antiproliferative effects of various extracts of different Morus species, but studies involving the in vitro cytotoxic effect of M.
The purpose of this study was to evaluate the phenolic composition and antioxidant activity of dimethyl sulfoxide extract of M. Mechanisms involved in the cytotoxic effect of DEM on PC-3 cells were then investigated in terms of apoptosis, mitochondrial membrane potential and cell cycle using flow cytometry, while caspase activity was investigated using luminometric analysis. Ascorbic acid and chlorogenic acid were the major phenolic compounds detected at HPLC analysis. DEM arrested the cell cycle of PC-3 cells at the G1 phase, induced apoptosis via increased caspase activity and reduced mitochondrial membrane potential.
Conclusions: Our results indicate that M. White piedra, black piedra, tinea versicolor, and tinea nigra : contribution to the diagnosis of superficial mycosis. Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra.

Intra- and interpopulation relationships and taxonomic status of Pinus nigra Arnold in Croatia according to morphology and anatomy of needles.
Full Text Available Intra- and interpopulational relationships and taxonomic status of six natural black pine populations Pinus nigra Arnold from Croatia were analyzed.
Special attention in this research was paid to the establishment of taxonomic status and distribution of stenoendemic Dalmatian black pine Pinus nigra Arnold subsp. Three morphological and twenty-one anatomical traits of needles were used as well as analysis by the methods of multivariate statistics. Most of the researched individuals showed strong population affiliation, whereas a clinal transition of morphological and anatomical traits of needles was determined among the populations.
The opinion of the existence of three subspecies of black pine on the territory of Republic of Croatia Pinus nigra Arnold subsp. Franco and Pinus nigra Arnold subsp. Fukarek was confirmed. For each of the three subspecies new ranges were represented. Since the Dalmatian black pine has been reduced to several populations only, and there are some signs of continuous diminishing of its range, this research points out the need of making an action plan to preserve all natural populations of this subspecies.
Dalbergia nigra is one of the most valuable timber species of its genus, having been traded for over years. Current methods, primarily comparative wood anatomy, are inadequate for conclusive species identification.
This study aims to find a set of anatomical characters that distinguish the wood of D. Dalbergia cearensis and D. Principal components analysis was unable to provide any further basis for separating the species. Wood anatomy alone cannot distinguish D. Diagnostic value of combined assessment of olfaction and sustantia nigra hyperechogenicity for Parkinson's disease.
We evaluated the combined prevalence of both disorders in patients diagnosed with PD and assessed their diagnostic yield compared to a sample with essential tremor ET and another group of healthy subjects. Patients diagnosed with PD and ET and treated in our outpatient clinic were enrolled. A total of 98 subjects were analysed, comprising 30 with PD, 21 with ET, and 47 controls. The respective prevalence rates of hyposmia SS Combined use of substantia nigra sonography and olfactory testing with SS, two rapid, safe, and accessible tests, was more specific than each isolated marker for distinguishing patients with PD from patients with ET and control subjects.
Since both markers have been described in very early phases of PD, combined use may be helpful in providing early diagnosis of PD. Ozone affects growth and development of Pieris brassicae on the wild host plant Brassica nigra. When plants are exposed to ozone they exhibit changes in both primary and secondary metabolism, which may affect their interactions with herbivorous insects. Here we investigated the performance and preferences of the specialist herbivore Pieris brassicae on the wild plant Brassica nigra under elevated ozone conditions.
The direct and indirect effects of ozone on the plant-herbivore system were studied. In both cases ozone exposure had a negative effect on P. However, in dual-choice tests larvae preferentially consumed plant material previously fumigated with the highest concentration tested, showing a lack of correlation between larval preference and performance on ozone exposed plants. Metabolomic analysis of leaf material subjected to combinations of ozone and herbivore-feeding, and focussing on known defence metabolites, indicated that P.
Full Text Available The aim of the study is to measure the in vitro antioxidant activity of elderberry Sambucus nigra fruit extract and to study its toxicity in a plant model system with regard to its possible application in food and agricultural industry. The antioxidant capacity of Sambucus nigra fruit powder was quantified by a photochemiluminescence method.
The study of phytotoxicity of aqueous solutions of powder extract was performed using Allium cepa as a test organism. Photochemiluminescence determinations showed a very high antioxidant capacity of the product but also revealed its cytotoxic effect, along with mitodepressive activity and even inhibiton of mitosis at the preprophase stage when the fruit extract was used at higher concentrations. At lower concentrations 0. The conclusion of our study is that Sambucus nigra fruit extract powder has a very high in vitro antioxidant activity and no mutagenic effects at low concentrations, which makes it recommendable for applications in the food industry.

Nine polycyclic aromatic hydrocarbons PAHs were analysed in pine needles of different ages from 6 to 30 months collected from two species, Pinus nigra and Pinus pinaster, in seven sites located along a transect from a suburban to a rural area of Genoa Italy.
In all sites and for both species, concentrations of more volatile PAHs phenanthrene, anthracene, fluoranthene, pyrene were higher than those for other less volatile PAHs, which are preferentially sorbed to airborne particulates benzo[a]anthracene, chrysene, benzofluoranthenes, benzo[a]pyrene. Concentrations of total PAHs found in P. In both pine species, concentrations of volatile PAHs increased according to needle age. Annual trends of other PAHs were more variable, with a general decrease in older needles.
E-mail: chimamb istge. Apelin ameliorates cognitive impairments in 6-hydroxydopamine-induced substantia nigra lesion in rats. Although Parkinson's disease PD is well known with its motor deficits, the patients often suffer from cognitive dysfunction.
Apelin, as the endogenous ligand of the APJ receptor, is found in several brain regions such as substantia nigra and mesolimbic pathway. However, the role of apelin in cognition and cognitive disorders has not been fully clarified. In this study the effects of apelin were investigated on cognitive disorders in rat Parkinsonism experimental model.
Morris water maze MWM , object location and novel object recognition tests were performed one month after the apelin injection. In conclusion, the data support the pro-cognitive property of apelin in 6-OHDA-induced cognitive deficit and provided a new pharmacological aspect of the neuropeptide apelin. In vitro antimicrobial and antiprotozoal activities, phytochemical screening and heavy metals toxicity of different parts of Ballota nigra.
The study was done to assess the phytochemicals flavonoids, terpenoids, saponins, tannin, alkaloids, and phenol in different parts root, stem, and leaves of Ballota nigra and correlated it to inhibition of microbes bacteria and fungi , protozoan Leishmania , and heavy metals toxicity evaluation.
In root and stem flavonoids, terpenes and phenols were present in ethanol, chloroform, and ethyl acetate soluble fraction; these were found to be the most active inhibiting fractions against all the tested strains of bacteria, fungi, and leishmania. While in leaves flavonoids, terpenes, and phenols were present in ethanol, chloroform, and n-butanol fractions which were the most active fractions against both types of microbes and protozoan leishmania in in vitro study.
Ethanol and chloroform fractions show maximum inhibition against Escherichia coli 17 mm. The phytochemical and biological screenings were correlated with the presence of heavy metals in selected plant Ballota nigra.
Cr was found above permissible value above 1. Ni was above WHO limit in B. Fe was above permissible value in all parts of B. Cd was above permissible value in all parts of the plant above 0. Cytoarchitectural neuroimaging remains critical for diagnosis of many brain diseases. Fluorescent dye-enhanced, near-infrared confocal in situ cellular imaging of the brain has been reported.
However, impermeability of the blood-brain barrier to most fluorescent dyes limits clinical utility of this modality. The differential degree of reflectance from brain tissue with unenhanced near-infrared imaging may represent an alternative technique for in situ cytoarchitectural neuroimaging.
We assessed the utility of unenhanced near-infrared confocal laser reflectance imaging of the cytoarchitecture of the cerebellum and substantia nigra in 2 fresh human cadaver brains using a confocal near-infrared laser probe.
Parts of the cerebellum and substantia nigra imaged using the probe were subsequently excised and stained with hematoxylin and eosin for histologic correlation. Near-infrared reflectance imaging revealed the 3-layered cytoarchitecture of the cerebellum, with Purkinje cells appearing hyperreflectant.
In the substantia nigra , neurons appeared hyporeflectant with hyperreflectant neuromelanin cytoplasmic inclusions. Cytoarchitecture of the cerebellum and substantia nigra revealed on near-infrared imaging closely correlated with the histology on hematoxylin-eosin staining. We showed that unenhanced near-infrared reflectance imaging of fresh human cadaver brain can reliably identify and distinguish neurons and detailed cytoarchitecture of the cerebellum and substantia nigra. Functional recovery of supersensitive dopamine receptors after intrastriatal grafts of fetal substantia nigra.
Interruption of the ascending dopamine neurons of the nigrostriatal pathway, by 6-hydroxydopamine 6-OHDA lesion in rats, produced a significant loss of the dopamine transport complexes labeled with the phencyclidine derivative [3H]BTCP.
This loss of dopamine innervation in the striatum was present at least 12 to 14 months after lesioning and was functionally manifested by ipsilateral rotation of the animals in response to amphetamine. In these same animals, in comparison to controls, there was a significant increase in the number Bmax of [3H]SCH labeled D-1 receptors in the striatum Ten to twelve months after the transplantation of homologous fetal substantia nigra into the denervated striatum, there was a significant decrease in amphetamine-induced turning behavior.
In these animals, there was an ingrowth of dopamine nerve terminals in the striatum as demonstrated by a return of [3H]BTCP binding. Accompanying this reinnervation was the normalization of D-1 and D-2 receptors to control values in the striatum as well as the return of D-1 receptors to prelesion densities in the substantia nigra. In a subgroup of transplanted rats, amphetamine continued to induce ipsilateral turning.
In these animals both D-1 and D-2 receptors remained supersensitive. These results support the hypothesis that the functional recovery of transplanted animals is due, in part, to reinnervation of the striatum. In addition, long-term alterations in receptor density may be related to the behavioral deficits that are associated with the 6-OHDA-lesioned rat. Morphological, biochemical and sensory characteristics of black mulberry fruits Morus nigra L.
This work aimed at the morphological, biochemical, technological and sensorial determination of black mulberry Morus nigra L.

Ultrasonic measurements along profiles at the surface of an object are well suited to characterize non-destructively weathering of natural stone near the surface. Ultrasonic waveforms of surface measurements in the frequency range between 10 kHz and kHz are often dominated by the Rayleigh wave - a surface wave that is mainly sensitive to the velocity and attenuation of S-waves in the upper 0.
The frequency dependence of the Rayleigh wave velocity may be used to analyze variations of the material properties with depth. Applications of ultrasonic surface measurements are shown for two buildings: the Roman Porta Nigra in Trier from the 3rd century AD and the Neptungrotte at Park Sanssouci in Potsdam designed by von Knobelsdorff in the 18th century. Both buildings belong to the world cultural heritage and restorations are planned for the near future.
It is interesting to compare measurements at these two buildings because they show the applicability of ultrasonic surface measurements to different natural stones. The Porta Nigra is made of local sandstones whereas the facades of the Neptungrotte are made of Carrara and Kauffunger marble.
At both buildings, Rayleigh-wave group velocities show huge variations. At the Porta Nigra they vary between ca. Note that velocities of elastic waves may increase e. The accuracy of the ultrasonic surface measurements, its reproducibility, and the influence of varying water saturation are discussed. Options for the analysis of ultrasonic waveforms are presented ranging from dispersion analysis to full waveform inversions for one-dimensional and two.
Evaluation of anti-inflammatory activity of prenylated substances isolated from Morus alba and Morus nigra. Chromatographic separation of root extracts of Morus alba and M.

Poplars accumulate high B concentrations and are thus used for the phytomanagement of B contaminated soils. Salix viminalis, Brassica juncea, and Lupinus albus were grown under some growing conditions for comparison. Poplar growth was unaffected at soil B treatment levels up to 93 mg kg Growth was progressively reduced at levels of and mg kg None of the other species survived at these substrate B levels.
At leaf B concentrations toxicity. The B accumulation ability of P. Alpha-synuclein suppression by targeted small interfering RNA in the primate substantia nigra. Full Text Available The protein alpha-synuclein is involved in the pathogenesis of Parkinson's disease and other neurodegenerative disorders. Its toxic potential appears to be enhanced by increased protein expression, providing a compelling rationale for therapeutic strategies aimed at reducing neuronal alpha-synuclein burden. Here, feasibility and safety of alpha-synuclein suppression were evaluated by treating monkeys with small interfering RNA siRNA directed against alpha-synuclein.
The siRNA molecule was chemically modified to prevent degradation by exo- and endonucleases and directly infused into the left substantia nigra. Results compared levels of alpha-synuclein mRNA and protein in the infused left vs. These findings could not be attributable to non-specific effects of siRNA infusion since treatment of a separate set of animals with luciferase-targeting siRNA produced no changes in alpha-synuclein. Infusion with alpha-synuclein siRNA, while lowering alpha-synuclein expression, had no overt adverse consequences.
In particular, it did not cause tissue inflammation and did not change i the number and phenotype of nigral dopaminergic neurons, and ii the concentrations of striatal dopamine and its metabolites. The data represent the first evidence of successful anti-alpha-synuclein intervention in the primate substantia nigra and support further development of RNA interference-based therapeutics.
Morus nigra plant leaves as biomonitor for elemental air pollution monitoring. Daud, M. Chemistry Div. The present paper deals with the determination of 36 elements in leaf samples of Morus nigra plant to assess their potential as biomonitor for elemental air pollution monitoring.
The leaf samples were collected in spring, summer and winter seasons from various sites in Islamabad with different types of anthropogenic activities as well as from a reference site with minimum of such activities. Twenty four soil samples from the respective sites were also analyzed. The reliability of the adopted procedures was established by analyzing the certified reference materials, i.
The enrichment values and Pollution Load Index PLI of the determined elements were computed and discussed accordingly. The elemental translocation from soil to roots, stem and leaves has also been studied by analyzing these parts of the same plant.
The results indicated that the leaves of Morus nigra plant have promising potential to monitor the extent of air pollution in the vicinity of industrial as well as in high traffic areas.

A potential problem is that P. Complement activation in the Parkinson's disease substantia nigra : an immunocytochemical study. The long-term use of nonsteroidal anti-inflammatory drugs has been associated, in retrospective studies, with decreased risk for PD, suggesting that inflammation may contribute to development of this disorder. The objective of this study was to determine the extent of complement activation, a major inflammatory mechanism, in PD. Nonparametric analyses were used to evaluate differences between groups and to evaluate correlations between complement staining, numbers of melanized neurons, and the duration of PD.
Staining was also prominent on melanized neurons. C9 immunoreactivity was significantly increased in PD vs. AD specimens, but unlike iC3b, the increased C9 staining in PD and young normal specimens did not achieve statistical significance vs.
Conclusion Complement activation occurs on Lewy bodies and melanized neurons in the PD substantia nigra. Early complement activation iC3b is increased on melanized neurons in PD vs. This latter finding suggests that complement. Three-dimensional magnetic resonance spectroscopic imaging in the substantia nigra of healthy controls and patients with Parkinson's disease. To investigate the substantia nigra in patients with Parkinson's disease three-dimensional magnetic resonance spectroscopic imaging with high spatial resolution at 3 Tesla was performed.
Regional variations of spectroscopic data between the rostral and caudal regions of the substantia nigra as well as the midbrain tegmentum areas were evaluated in healthy controls and patients with Parkinson's disease. Nine patients with Parkinson's disease and eight age- and gender-matched healthy controls were included in this study.
Data were acquired by using three-dimensional magnetic resonance spectroscopic imaging measurements. The ratios between rostral and caudal voxels of the substantia nigra as well as the midbrain tegmentum areas were calculated for the main-metabolites N-acetyl aspartate, creatine, choline, and myo-inositol.
In all subjects spectra of acceptable quality could be obtained with a nominal voxel size of 0. Chemotaxonomic significance of the terpene composition in natural populations of Pinus nigra J.

Species verification of Dalbergia nigra and Dalbergia spruceana samples in the wood collection of the Forest Products Laboratory. To evade endangered timber species laws, unscrupulous importers sometimes attempt to pass protected Dalbergia nigra as look-alike but unprotected, Dalbergia Spruceana.
Wood density and fluorescence properties are sometimes used to identify the species. Although these properties are useful and do not require special equipment, Increasing evidence suggests that oxidative stress plays a major role. The resulting increase in reactive oxygen species triggers a sequence of events that leads to cell damage, activation of microglia cells and neuroinflammatory responses.
Our objective was to study whether chronic exposure to low doses of ozone, which produces oxidative stress itself, induces progressive cell death in conjunction with glial alterations in the substantia nigra. Animals were exposed to an ozone-free air stream control or to low doses of ozone for 7, 15, 30, 60, or 90 days. Each group underwent 1 spectrophotometric analysis for protein oxidation; 2 western blot testing for microglia reactivity and nuclear factor kappa B expression levels; and 3 immunohistochemistry for cytochrome c, GFAP, Iba-1, NFkB and COX Our results indicate that ozone induces an increase in protein oxidation levels, changes in activated astrocytes and microglia, and cell death.
NFkB and cytochrome c showed an increase until 30 days of exposure, while cyclooxygenase 2 in the substantia nigra increased from 7 days up to 90 days of repetitive ozone exposure.

Development of a reliable method for determining sex for a primitive rodent, the Point Arena mountain beaver Aplodontia rufa nigra. The mountain beaver Aplodontia rufa is a primitive species of rodent, often considered a living fossil.
The Point Arena mountain beaver Aplodontia rufa nigra is an endangered subspecies that occurs in a very restricted range in northern California. Efforts to recover this taxon have been limited by the lack of knowledge on their demography, particularly sex and age Rhabdomyosarcoma in a terrestrial tortoise Geochelone nigra in Nigeria: A case report. Full Text Available A skeletal muscle tumour rhabdomysarcoma was diagnosed in a 4-year-old captive female terrestrial tortoise Geochelone nigra weighing 7 kg presented at the Veterinary Teaching Hospital, University of Ibadan, Ibadan, Nigeria.
The tumour was located at the anterior right portion of the body and ventral to the carapace. The location of the tumour prevented the tortoise from extending its head from the body. The tumour was a sessile, smooth white mass, with a soft myxomatous consistency. The histological features that were diagnostic of rhabdomyosarcoma included a sparse population of haphazardly arranged spindle-shaped cells within a homogenous matrix anisocytosis, occasional tumour giant and binucleate cells, and some well differentiated myofibrils with cross striations within the cytoplasm.
The paucity of information on tumours in the land tortoise was the reason for this report, which appears to be the first report of rhabdomyosarcoma in the tortoise. Diversity and expression of nitrogenase genes nifH from ectomycorrhizas of Corsican pine Pinus nigra. The diversity of bacterial nitrogenase genes nifH and their mRNA transcription in ectomycorrhizas of Corsican pine Pinus nigra were examined. Several different nifH sequences were detected and the bacteria actively transcribing nifH were different from those whose genes were detected through DNA-based PCR.
Putative nitrogenase amino acid sequences revealed that more than half of the nifH products were derived from methylotrophic bacteria, such as Methylocella spp. The next most frequent sequence types were similar to those from Burkholderia.
Effects of water stress on germination of Pinus nigra Arnold. Climate change, global warming and the deterioration of related environmental conditions cause an important problem for forest tree species. For this reason, it is necessary to determine the response of trees to these conditions.

Enkephalin, dynorphin and substance P in postmortem substantia nigra from normals and schizophrenic patients. Three peptide neuromodulators that are found in high concentration in the subtantia nigra : dynorphin A 1,8-met5-enkephalin-arg6-gly7-leu8 and substance P, were measured by specific radioimmunoassays in nigral tissue from normals and schizophrenics postmortem.
Substance P and dynorphin were unchanged between the two groups. However, the proenkephalin-derived peptide was significantly elevated in the schizophrenic group. The immunoreactivity was identified as authentic met5-enkephalin-arg6-gly7-leu8 by high pressure liquid chromatography. The data suggest that a different set of regulatory controls exists for nigral enkephalin peptides as compared to dynorphin and substance P, and that the former system may be disordered in schizophrenia.
The elder Sambucus spp. Previous studies have demonstrated the antimicrobial properties of elderberry liquid extract against human pathogenic bacteria and also influenza viruses.
