brain drain der europäischen Informationswissenschaft
Authors: Hillebrand Vera
Published: September 2017

Diese Studie erforschte die Mobilitätsmuster von 882 aktiven Informationswissenschaftlern, die sich von 2014 bis 2016 an der iConference beteiligten. Analysiert wurde, ob es in dieser informationswissenschaftlichen Community einen brain drain – eine Abwanderung von Forschenden ins Ausland – gibt. Die Ergebnisse zeigen zwei Trends: amerikanische Informationswissenschaftler_innen verlassen selten ihren Kontinent und haben keine internationale Erfahrung, während die Auswanderungsrate unter Forschenden aus Asien und Europe nach Nordamerika hoch ist. 90 Prozent aller Promovierenden aus dem Sample leben gerade in Nordamerika. Ein wichtiger Faktor für das Mobilitätsverhalten scheint die englische Sprache zu sein. Ausländische Studierende wählen in Europa englischsprachige Umgebungen.

Corporatism, Informality and Democracy in the Streets of Mexico City
Authors: De la Garza Toledo Enrique , Gayosso Ramírez José Luis , Pogliaghi Leticia
Published: September 2017

While the end of corporatism has been frequently announced, we argue that in Mexico it persists under contemporary neo-liberalism, albeit with new characteristics. To explore these characteristics, we use the concept of corporatism in a broader sense. That is, we assume that it not only involves relationships between trade unions, business associations and the state, but also with other civil society organisations. For our study, this includes informal worker organisations, in particular of taxi drivers and street vendors. We analyse these organisations, their relationship with the work itself (especially the occupation of public space) and their linkages with local government. We conclude that while some organisations remain independent of government control, many are imbricated in corporate relationships with the state, giving rise to an informal corporatism. Finally, we reflect on the special features this informal corporatism shows.

Published: September 2017

In the double-step paradigm, healthy human participants automatically correct reaching movements when targets are displaced. Motor deficits are prominent in Parkinson’s disease (PD) patients. In the lone investigation of online motor correction in PD using the double-step task, a recent study found that PD patients performed unconscious adjustments appropriately but seemed impaired for consciously-perceived modifications. Conscious perception of target movement was achieved by linking displacement to movement onset. PD-related bradykinesia disproportionately prolonged preparatory phases for movements to original target locations for patients, potentially accounting for deficits. Eliminating this confound in a double-step task, we evaluated the effect of conscious awareness of trajectory change on online motor corrections in PD. On and off dopaminergic therapy, PD patients (n= 14) and healthy controls (n= 14) reached to peripheral visual targets that remained stationary or unexpectedly moved during an initial saccade. Saccade latencies in PD are comparable to controls’. Hence, target displacements occurred at equal times across groups. Target jump size affected conscious awareness, confirmed in an independent target displacement judgment task. Small jumps were subliminal, but large target displacements were consciously perceived. Contrary to the previous result, PD patients performed online motor corrections normally and automatically, irrespective of conscious perception. Patients evidenced equivalent movement durations for jump and stay trials, and trajectories for patients and controls were identical, irrespective of conscious perception. Dopaminergic therapy had no effect on performance. In summary, online motor control is intact in PD, unaffected by conscious perceptual awareness. The basal ganglia are not implicated in online corrective responses.
Emergence of β-Band Oscillations in the Aged Rat Amygdala during Discrimination Learning and Decision Making Tasks
Authors: Samson Rachel D. , Lester Adam W. , Duarte Leroy , Venkatesh Anu , Barnes Carol A.
Published: September 2017

Older adults tend to use strategies that differ from those used by young adults to solve decision-making tasks. MRI experiments suggest that altered strategy use during aging can be accompanied by a change in extent of activation of a given brain region, inter-hemispheric bilateralization or added brain structures. It has been suggested that these changes reflect compensation for less effective networks to enable optimal performance. One way that communication can be influenced within and between brain networks is through oscillatory events that help structure and synchronize incoming and outgoing information. It is unknown how aging impacts local oscillatory activity within the basolateral complex of the amygdala (BLA). The present study recorded local field potentials (LFPs) and single units in old and young rats during the performance of tasks that involve discrimination learning and probabilistic decision making. We found task- and age-specific increases in power selectively within the β range (15–30 Hz). The increased β power occurred after lever presses, as old animals reached the goal location. Periods of high-power β developed over training days in the aged rats, and was greatest in early trials of a session. β Power was also greater after pressing for the large reward option. These data suggest that aging of BLA networks results in strengthened synchrony of β oscillations when older animals are learning or deciding between rewards of different size. Whether this increased synchrony reflects the neural basis of a compensatory strategy change of old animals in reward-based decision-making tasks, remains to be verified.
An Emerging Field of Primate Social Neurophysiology: Current Developments
Authors: Chang Steve W. C.
Published: September 2017

Recently, there has been increased interest in investigating neurophysiological mechanisms underlying social interactions using a nonhuman primate model system. Several studies in this subfield, known as primate social neurophysiology, have begun to provide novel insights into how single neurons encode socially-relevant variables. This opinion piece intends to provide insight into the state of this field. In doing so, it discusses some common principles learned from primate social neurophysiology experiments.
Cell-Specific RNA Binding Protein Rbfox2 Regulates CaV2.2 mRNA Exon Composition and CaV2.2 Current Size

Published: September 2017

The majority of multiexon mammalian genes contain alternatively spliced exons that have unique expression patterns in different cell populations and that have important cell functions. The expression profiles of alternative exons are controlled by cell-specific splicing factors that can promote exon inclusion or exon skipping but with few exceptions we do not know which specific splicing factors control the expression of alternatively spliced exons of known biological function. Many ion channel genes undergo extensive alternative splicing includingCacna1bthat encodes the voltage-gated CaV2.2 α1 subunit. Alternatively spliced exon 18a inCacna1bRNA encodes 21 amino acids in the II-III loop of CaV2.2, and its expression differs across the nervous system and over development. Genome-wide, protein-RNA binding analyses coupled to high-throughput RNA sequencing show that RNA binding Fox (Rbfox) proteins associate with CaV2.2 (Cacna1b) pre-mRNAs. Here, we link Rbfox2 to suppression of e18a. We show increased e18a inclusion in CaV2.2 mRNAs: (1) after siRNA knockdown of Rbfox2 in a neuronal cell line and (2) in RNA from sympathetic neurons of adult compared to early postnatal mice. By immunoprecipitation of Rbfox2-RNA complexes followed by qPCR, we demonstrate reduced Rbfox2 binding upstream of e18a in RNA from sympathetic neurons of adult compared to early postnatal mice. CaV2.2 currents in cell lines and in sympathetic neurons expressing only e18a-CaV2.2 are larger compared to currents from those expressing only Δ18a-CaV2.2. We conclude that Rbfox2 represses e18a inclusion during pre-mRNA splicing of CaV2.2, limiting the size of CaV2.2 currents early in development in certain neuronal populations.

Microglia are resident macrophages of the central nervous system that contribute to homeostasis and neuroinflammation. Although known to play an important role in brain development, their exact function has not been fully described. Here, we show that in contrast to healthy adult and inflammation‐activated cells, neonatal microglia show a unique myelinogenic and neurogenic phenotype. A CD11c+ microglial subset that predominates in primary myelinating areas of the developing brain expresses genes for neuronal and glial survival, migration, and differentiation. These cells are the major source of insulin‐like growth factor 1, and its selective depletion from CD11c+ microglia leads to impairment of primary myelination. CD11c‐targeted toxin regimens induced a selective transcriptional response in neonates, distinct from adult microglia. CD11c+ microglia are also found in clusters of repopulating microglia after experimental ablation and in neuroinflammation in adult mice, but despite some similarities, they do not recapitulate neonatal microglial characteristics. We therefore identify a unique phenotype of neonatal microglia that deliver signals necessary for myelination and neurogenesis.

Published: September 2017

The Hippo pathway plays essential roles in organ size control and cancer prevention via restricting its downstream effector, Yes‐associated protein (YAP). Previous studies have revealed an oncogenic function of YAP in reprogramming glucose metabolism, while the underlying mechanism remains to be fully clarified. Accumulating evidence suggests long noncoding RNAs (lncRNAs) as attractive therapeutic targets, given their roles in modulating various cancer‐related signaling pathways. In this study, we report that lncRNA breast cancer anti‐estrogen resistance 4 (BCAR4) is required for YAP‐dependent glycolysis. Mechanistically, YAP promotes the expression of BCAR4, which subsequently coordinates the Hedgehog signaling to enhance the transcription of glycolysis activators HK2 and PFKFB3. Therapeutic delivery of locked nucleic acids (LNAs) targeting BCAR4 attenuated YAP‐dependent glycolysis and tumor growth. The expression levels of BCAR4 and YAP are positively correlated in tissue samples from breast cancer patients, where high expression of both BCAR4 and YAP is associated with poor patient survival outcome. Taken together, our study not only reveals the mechanism by which YAP reprograms glucose metabolism, but also highlights the therapeutic potential of targeting YAP‐BCAR4‐glycolysis axis for breast cancer treatment.

Here we describe the sequencing and assembly of the pathogenic fungus Lomentospora prolificans using a combination of short, highly accurate Illumina reads and additional coverage in very long Oxford Nanopore reads. The resulting assembly is highly contiguous, containing a total of 37,627,092 bp with over 98% of the sequence in just 26 scaffolds. Annotation identified 8896 protein-coding genes. Pulsed-field gel analysis suggests that this organism contains at least 7 and possibly 11 chromosomes, the two longest of which have sizes corresponding closely to the sizes of the longest scaffolds, at 6.6 and 5.7 Mb.

Identification of quantitative trait loci (QTL) involved in the variation of hybrid value is of key importance for cross-pollinated species such as maize (Zea mays L.). In a companion paper, we illustrated a new QTL mapping population design involving a factorial mating between two multiparental segregating populations. Six biparental line populations were developed from four founder lines in the Dent and Flint heterotic groups. They were crossed to produce 951 hybrids and evaluated for silage performances. Previously, a linkage analysis (LA) model that assumes each founder line carries a different allele was used to detect QTL involved in General and Specific Combining Abilities (GCA and SCA, respectively) of hybrid value. This previously introduced model requires the estimation of numerous effects per locus, potentially affecting QTL detection power. Using the same design, we compared this “Founder alleles” model to two more parsimonious models, which assume that (i) identity in state at SNP alleles from the same heterotic group implies identity by descent (IBD) at linked QTL (“SNP within-group” model) or (ii) identity in state implies IBD, regardless of population origin of the alleles (“Hybrid genotype” model). This last model assumes biallelic QTL with equal effects in each group. It detected more QTL on average than the two other models but explained lower percentages of variance. The “SNP within-group” model appeared to be a good compromise between the two other models. These results confirm the divergence between the Dent and Flint groups. They also illustrate the need to adapt the QTL detection model to the complexity of the allelic variation, which depends on the trait, the QTL, and the divergence between the heterotic groups.
The impact of growth stimulators and retardants on the utilization of reserve lipids by sunflower seedlings

Published: September 2017

Using growth stimulators and anti-gibberillin preparations of different chemical compounds, we created different pressures in the coordinate covalent bond systems during germination of sunflower seeds. Using gibberellin and treptolem growth stimulators and Paclobutrazol and Chlormequat-Chlorid anti-gibberillin preparations is an efficient method of reconstructing coordinate covalent bond during the germination of seeds of oil-bearing crops. It allows determination of the role of the hormone factor in the utilization of reserve lipids over the heterotrophic phase of plant development. Blocking the synthesis of gibberellins by retardants caused decrease in activity of lipase, hydrolysis of reserve lipids and the meristem, which resulted in decrease in the energy of germination. Compared to the control, the impact of gibberellin increased the content of butyric acid, and the impact of Paclobutrazol reduced the content of butyric acid. Linoleic acid showed exactly the opposite changes. In relation to the control, a significant increase in the content of non-saturated linoleic acid was observed in both variants of the experiment. Gibberellic acid stimulated and Paclobutrazol slowed the usage of free higher fatty acids for the process of morphogenesis.
Biomorphology and rhythm of seasonal development of the relic species Lobelia dortmanna in oligotrophic lakes of Tver region

Published: September 2017

This article covers the morphology of the vegetative and generative sphere of a rare relic species, Lobelia dortmanna L. (Lobelioideae). This is the first time that using the modular approach a study has analysed the shoot system of this species and described the structures of all three categories: elementary (EM), universal (UM) and basic (OM). This paper describes the life form and analyses the rhythm of seasonal development of the species in the lakes of Tver oblast, and provides data on the seed productivity. As a life form, L. dortmanna is a herbaceous polycarpic, un clearly polycentric shallow-rooted plant with a fibrous root system and non-specialized morphological disintegration. The sympodially growing shoot-system of the plant is formed by two types of different-aged anisotropic replacement shoots: dicyclic vegetative-generative semirosette and annual vegetative rosette shoots. The indicator of actual seed productivity equals on average up to 1621 ± 451 seeds per single vegetative-generative shoot. The module structure of L. dortmanna is presented by 10 variants of elementary modules. The main modules are formed on the basis of a monocarpic dicyclic anisotropic monopodial shoot with the following morpho-functional zones distinguished: 1) the lower zone of inhibition; 2) the recovery zone; 3) the upper zone of inhibition 4) the latent generative zone; 5) the main inflorescence. The functional role of the first three morpho-functional zones of a monocarpic shoot is performed by a minimum number of variants of elementary modules. In the rhythm of seasonal development, the authors distinguished 7 consecutive stages: 1) the period of relative rest; 2) vegetative phase; 3) the phase of budding; 4) flowering; 5) frui ting; 6) secondary activities. By the character of rhythm of seasonal development, L. dortmanna belongs to the group of evergreen plants with a long growing season and flowering in middle-late summer.

Our experiments studied changes in lipid compound of bile of non-purebred male rats under the condition of social stress while the preparation “Korvitin” was used against the stress. Using the method of thin-layer chromatography, we determined the concentrations of phospholipids, cholesterol and its esters, free fatty acids and triglycerides in the animals’ bile, which was obtained through vivesection a day and a month after the rats were first subjected to chronic social stress (model of social defeat), and also in the bile of the animals which were treated intragastrically with “Korvitin” against the stress (1 mg/kg, 7 days). In the bile of the male rats which experienced chronic social stress the concentration of free cholesterol decreased and the content of its esters increased both immediately after the initiation of stress and after a month of exposure to stress. The concentration of free fatty acids in the bile decreased after modeling chronic social stress, but increased in liver secretion, taken a month after the animals first experienced stress. In the bile of male rats immediately after the procedure of exposing the animals to stress, the content of phospholipids decreased. Using “Korvitin” during the modeling of social stress caused decrease in the content of phospholipids in the rats’ bile and caused significant increase in the concentration of free fatty acids, triglycerides and cholesterol esters in the liver secretion. The study found significant changes in the concentration of lipids in the bile and in their distribution in the organism of male rats under the conditions of experimentally induced chronic stress. The effect of stress on the bile of rats requires further study for determining its pathogenic role.
Morphological and biochemical mechanisms of changes in buccal epithelocytes and erythrocytes in children suffering psycho-emotional stress
Authors: Gan R. Z. , Popel’ S. L.
Published: September 2017

The article provides experimental data on the impact of psychoemotional stress on cytological, morphometric, immunological and biochemical indicators in 7–11 year old children. We examined 100 children of primary school age, who were divided into the main group (50 children who had been resettled from the combat zone) and the control group (50 children, who live in Ivano-Frankivs’k). We used morphological (light-optical and electromicroscopic) and mor phometric analysis of buccal epithelium and peripheral blood erythrocytes, biochemical methods for identifying the products of peroxidation of lipids, ceruloplasmin and ferritin according to widely used methods. Morphological methods revealed that under psychoemotional stress, the size of the nuclei and buccal epithelial cells significantly decreases, and their nucleo-cytoplasmic ratio changes towards increase in the share of cytoplasm, and the indicators of coefficient of buccal epithelial cell shape indicate significant deformation of those cells. Similar changes were observed in the erythrocytes of peripheral blood. In the blood, we observed an increase in the CD95+ concentration of lymphocytes. Clearly manifested changes in morphological and morphometric indicators of buccal epithelium and erythrocytes when there is an increase in the CD95+ level of lymphocytes indicate the development of a systematic apoptosis reaction of the studied cells in the condition of psychoemotional stress. Also we observed clearly manifested changes in the coefficient of erythrocytes’ shape, their size and perimeter, increase in the number of reversibly and irreversibly changed cells, which with increase in free radical oxidation, indicates disorders in the organism’s antioxidant protection system in general and requires a pathogenically grounded programme of treating complications related to psychoemotional stress among 7–11 years old children who were resettled fom the combat zone in Eastern Ukraine.
Left ventricular diastolic function in patients with obstructive sleep apnoea syndrome and obesity

Published: September 2017

Obstructive sleep apnea syndrome (OSAS) is a chronic disease characterized by recurrent episodes of complete or partial obstruction of the upper airways during sleep and results in sleep fragmentation, night hypoxemia, and daytime sleepiness. The aim of this study was to investigate the state of left ventricular diastolic function in patients with first diagnosed COAS and obesity and to define the determinants of diastolic dysfunction in this category of patients. There were 46 patients (33 men and 13 women) with OSAS and obesity and 52 patients with obesity without OSAS enrolled in the study. The control group included 22 practically healthy individuals. Each patient underwent assessment of body mass index (BMI), 24-hour ambulatory blood pressure monitoring, cardiorespiratory monitoring, transthoracic echocardiography. We found that patients with OSAS and obesity had significant impairment of diastolic function in comparison with patients with obesity without OSAS, which manifested itself in decreasing of E/A ratio, increasing deceleration time and increasing isovolumic relaxation time. Increasing body mass index and increasing level of hypoxia lead to impairment of diastolic dysfunction. Diastolic dysfunction was diagnosed in 4 obese patients without OSAS and in 17 patients with OSAS and obesity. All patients with diastolic dysfunction had second or third stage obesity and severe OSAS. Left ventricular hypertrophy was diagnosed in 9 patients with OSAS and obesity. Patients with concentric hypertrophy had significantly lower E/A in comparison with patients without hypertrophy or with concentric remodeling. We found that the deceleration time has positive correlation with body mass index and desaturation index and negative correlation with min SaO2. Isovolumic relaxation time correlated only with desaturation index. According to the results of univariable regression analysis, five variables were allocated: body mass index, age, desaturation index, index apnea-hypopnea and left ventricular mass index. The multivariate analyses, after adjustment for age and sex and stepwise regression, showed that only the desaturation index was an independent predictor of left ventricular diastolic dysfunction in patients with OSAS and obesity. Obstructive sleep apnea syndrome combined with obesity leads to a deterioration of the diastolic function of the left ventricle even in patients without cardio-vascular diseases. The state of the diastolic function of the left ventricule worsens with an increase in the severity of hypoxic disorders in the syndrome of obstructive sleep apnea and with the degree of obesity. In multivariate regression analysis, the desaturation index was a predictor of left ventricular diastolic dysfunction in patients with obstructive sleep apnea syndrome and obesity.

The importance of biomarkers to predict recovery following total hip arthroplasty (THA) is still unclear to clinicians. To assess the preoperative biomarkers of patients with pseudoarthrosis of the femoral neck and their dynamics in the early postoperative period after THA, 50 patients aged 33 to 82 years old, 18 males and 32 females diagnosed with pseudoarthrosis of the femoral neck after failed internal fixation and failed conservative management were studied. The control group consisted of 30 healthy people aged 27 to 50 years, 13 males, 17 females. Patients’ blood was examined for biochemical markers upon admission, and then on the 7th and 14th days after surgery. Their blood serum content of total protein, albumin, glycoproteins, sialic acids, chondroitin sulfates, haptoglobin, glucose, cholesterol, triglycerides, ALT, AST, alkaline phosphatase, GGT, acid phosphatase, thymol index; interleukins (IL-1, IL-4 and IL-6.) and C-reactive protein was measured. The content of glycoproteins in the blood exceeded normal by 2.3 times, chondroitin sulfate by 4.7 times, sialic acids by 1.5 times, haptoglobin by 55.8%, fibrinogen by 19.1%, globulin by 19,6%, alkaline phosphatase activity by 72.3%, IL-1 by 94.7 and IL-6 by 3 times, C-reactive protein by 2.6 times. After THA there was a gradual decrease in blood biochemical and immunological markers. The most informative laboratory markers were glycoproteins, chondroitin sulfates, sialic acids, haptoglobin, activity of alkaline phosphatase, IL-1, IL-6 and IL-4, and C-reactive protein. Subsequent research is required to validate these dynamics.

Pacientes ansiosos tendem a ter complicações no cateterismo, o que pode levar a dificuldades no procedimento. As intervenções psicológicas visam auxiliar o paciente a vivenciar mais tranquilamente todas as etapas do tratamento. O objetivo do estudo foi verificar a efetividade de uma vídeo-orientação em relação aos níveis de ansiedade e medo em pacientes submetidos ao cateterismocardíaco. Para tanto, foi realizada uma intervenção quasi-experimental com um grupo intervenção (30) e um não-intervenção (30), idade média 62 anos, 37 homens e 23 mulheres. Foram aplicados 1) Inventário de Stress de Lipp, escala de ansiedade de Beck e questionário de autorrelato para todos; 2) vídeo-orientação para o grupo intervenção; 3) questionário de autorrelato para todos. A análise estatística demostrou significativamente melhor conhecimento do procedimento, menor preocupação e menor ansiedade e medo no grupo intervenção. Conclui-se que a vídeo-orientação foi eficaz, atendendo à necessidade de qualificação da assistência psicológica.

Foi objetivo do estudo reunir evidências de validade de estrutura interna e convergente da Escala de Consciência Plena no Trabalho. Participaram do estudo 383 trabalhadores, de ambos os sexos (65,7% do sexo feminino), com idades variando entre 18 e 70 anos (M = 34,5; DP = 11,7), que responderam à versão brasileira da escala e a instrumentos para avaliação de outros construtos. As análises fatoriais confirmatórias demonstraram a existência de sete itens concentrados em um único fator, com índice de consistência interna de 0,81. Na validação convergente, a escala correlacionou-se positiva e moderadamente com o engajamento laboral, a saúde mental e os afetos positivos dirigidos ao trabalho, e negativa e moderadamente com o neuroticismo. A escala apresentou, portanto, evidências de validade de estrutura interna, de precisão e de validade convergente, o que recomenda seu uso futuro em pesquisas e diagnósticos organizacionais sobre a consciência plena no trabalho.

Published: September 2017

O objetivo deste estudo é identificar as contribuições de pesquisas empíricas publicadas em periódicos científicos sobre a caracterização do processo de cumprimento da medida socioeducativa de internação no Brasil. Trata-se de uma revisão sistemática da literatura que analisou 30 trabalhos, cujos resultados foram tratados a partir da análise temática. Observou-se a precarização da estrutura física e das atividades ofertadas, bem como um clima organizacional coercitivo marcado por relações interpessoais hostis, o que resulta na perda da identidade pessoal, sofrimento, reincidência e preconceito na comunidade. Elementos positivos foram também destacados, referentes à adequação da estrutura física e das atividades desenvolvidas, a um clima organizacional livre de violência e à vinculação dos adolescentes com seus familiares e funcionários, o que favorece a aprendizagem e proteção. A revisão identificou a prevalência de práticas coercitivas sobre as pedagógicas e ressaltou a necessidade de pesquisas que investiguem os processos decorrentes da privação de liberdade.

Authors: Santos Gilney Charll , Chaves Leonardo Silva , Albuquerque Ulysses Paulino
Published: September 2017

Seed dispersal is a key ecological process for the maintenance of biodiversity and ecosystem functioning and is undoubtedly critical to the provision of valuable ecosystem benefits to humanity. However, the loss or population reduction of seed-dispersing animals, especially the medium and large ones, has increasingly compromised important ecological processes and associated ecosystem benefits. Thus, we aimed to review researches that examined how the loss or reduction of seed-dispersing fauna affects the functioning of ecosystems and, consequently, humanity. We believe that this review provides new directions for future research in the field of conservation science that may contribute to policy initiatives and management and conservation plans.

Published: September 2017

Phylogeographical and philodinamic studies have shown that the hepatitis C virus began to circulate in the human population about 500–2000 years ago on the A frican continent and only in the 20th century, this virus received the ubiquitary distribution. According to WHO in the world more than 71 million people are chronically infected by the hepatitis C virus, more than half of them live in A frica and South-East Asia. At the same time, the actual prevalence of hepatitis C in most countries of sub-Saharan A frica, including the Republic of Guinea, remains poorly understood.The aim of this study was to evaluate the occurrence of serological and molecular markers of hepatitis C on a random small selection of blood samples obtained from healthy adults of the Republic of Guinea.Materials and methods. Serum and plasma blood samples obtained from thirty one healthy adults of 24–71 years old of the Republic of Guinea were examined. Blood samples were collected in 2015–2016 years. The serum samples were analyzed for the presence of total anti-HCV (IgG+IgM),  of specific antibodies to the core, the NS3, the NS4 and the NS5B HCV proteins, of core antigene with “DS-ELISA-ANTI-HCV-GM”, “DS-ELISA-ANTI-HCV-SPEKTRE-GM”, “DS-ELISA-HCV-Ag” detection kits (RPC “Diagnostic Systems”, Russia), respectively. RNA HCV were detected by RT-PCR with detection kit “A mpliSens HCV-FRT” (CRIE, Moscow) and by nested-PCR using the primers from 5’UTR region. HCV genotypes were determined by RT-PCR  with detection kit “A mpliSens HCV-genotype FRT” (CRIE, Moscow) and by phylogenetic analysis based on the 5’UTR region.Results and discussion. In this pilot study, the presence of HCV markers was confirmed in 3 (9.68%, 95% CI 3.35–24.90) of 31 examined persons. Two of them had RNA HCV. Based on the phylogenetic analysis of the 5’UTR region of the HCV genome, the isolate obtained from person No. 5 belonged to genotype 1, and the isolate obtained from person No. 6 belonged to genotype 2. The obtained results together with the analyzed literature data indicate a significant burden of hepatitis C in the Republic of Guinea, and also indicate the need to develop both an algorithm of diagnostic criteria and the improvement of diagnostic test systems for mass screening of the A frican population in order to establish the proportion of persons involved in epidemic process.

Septic implications at patients aren’t a rarity, especially in surgical, pediatric and obstetric practice now. However not enough attention, despite epidemic of this disease is paid to implication of a sepsis at patients with HIV infection now. Clinical laboratory implications of a sepsis at 36 patients with HIV infection are analysed. The main group is presented by patients with a lethal outcome (n = 18), control — with a positive outcome of a stationary stage of treatment (n = 18). Work is carried out on materials of the Infectious hospital No. 1 of D.M. Dalmatov of Omsk. At HIV-positive patients the stage of secondary diseases met most more often. Anti-retrovirus therapy was accepted only by 33% of patients in control group. At the died patients the hyperthermia arose after development of complaints from organs and systems and lasted less than 15 days. Low indicators of the CD4+ lymphocytes and a high virus load of HIV in a blood of patients with a lethal outcome became perceptible. In the general blood test thrombocytopenias, eosinopenias, monocytopenias, in the biochemical analysis — augmentation of the general bilirubin, thymol turbidity test, prothrombin ratio, urea were more often taped. At a bacteriological blood analysis various microflora with prevalence of S. aureus, sometimes in combination with Gram-negative flora was taped. Symptoms of an infectious endocarditis were taped at every second dead of the HIV-positive patient. Almost at all patients radiological changes in a pulmonary tissue were taped. Thus, clinical implications at patients with HIV infection are few symptoms and not typicalness that demands further studying.

Inf luenza and acute respiratory viral infections (ARVI) account for up to 90% of the total reported infectious morbidity annually in Russia. The economic damage from these infections reaches 86% of the economic losses associated with infectious diseases. As a result of antigenic drift or a shift, new variants of the inf luenza virus, including pandemic strains, appear. In 2009, an inf luenza pandemic arose due to the shifter version of the inf luenza A (H1N1) pdm09 virus. This virus caused epidemic rises of inf luenza in the world in subsequent years. The aim of the study was to describe the epidemic process of inf luenza in January–March 2016 in St. Petersburg. Materials and methods. The incidence of inf luenza and acute respiratory viral infections in St. Petersburg was recorded according to statistical coupons by age groups of the population. Examined nasopharyngeal f lushes received no later than 3–4 days from the onset of the disease, and in case of a lethal outcome — sectional material (bronchi, trachea, lungs, spleen tissues). The detection of RNA of inf luenza viruses was carried out in RT-PCR (Amplicenc Inf luenza virus A/B, Amplicenc Inf luenza virus A/H1-swine-FL, Amplicenc Inf luenza virus A типа-FL,  «Interlabservice», Moscow). Isolation of inf luenza viruses from the clinical material was carried out on culture by the MDSC cell. Isolates were typed in RTGA with diagnostic sera to reference and epidemic inf luenza viruses. Isolation of inf luenza viruses from the clinical material was carried out on culture by the MDSC cell. Isolates were typed in RTGA with diagnostic sera to reference and epidemic inf luenza viruses. Results. In 2016, the incidence of inf luenza in St. Petersburg was 81.38 per 100 000 population and was 4.1 times higher than the incidence rate in 2015. The epidemic rise in the incidence of inf luenza and ARVI began with the 3rd calendar week, lasted 6 weeks, with a peak incidence at the 5th calendar week. In total, 398 675 people (7.6% of the population) were ill during this period, including adults — 184 658 (4%), children 0–14 years old — 214 017 or 31.5% of this age group. The greatest number of cases among children was registered in the group of 3–6 years — 87 766 (41.0%). Among the ill children, 86.2% attended pre-school children’s institutions (kindergartens). During the epidemic recovery in 2016, inf luenza viruses were detected in 297 people (46.2%): the inf luenza A (H1N1) virus pdm09 in 97.1% of cases, A (H3N2) — 0.6%, B — 2.3%. There were 102 deaths from complications after the inf luenza, including 101 cases of inf luenza A (H1N1) and A (H3N2) inf luenza A (H1N1) pdm09 confirmed by PCR. Among the dead 101 adults (including 2 pregnant women) and one child. All of them were not vaccinated against the f lu earlier. All deceased adults suffered from chronic physical illnesses.

Published: September 2017

RESUMO O chumbinho do pessegueiro causado por Wilsonomyces carpophilus é uma das doenças comumente encontrada na cultura, comprometendo a área foliar e consequentemente reduzindo a produção e a qualidade dos frutos. Considerando que o comportamento desta doença é pouco conhecido, esse trabalho teve como objetivo avaliar o progresso temporal ao longo do ciclo produtivo em diferentes genótipos de pessegueiro. O experimento foi realizado no pomar de pessegueiro do Instituto Federal Catarinense -IFC/Campus Rio do Sul. Foram avaliados os genótipos Granada, Dourado 1, Dourado 2, Douradão, Ouro, Chimarrita, Flordaprince, Premier, Aurora e Della Nona. Selecionaram-se quatro plantas de cada genótipo e avaliou-se a severidade estimada da doença semanalmente, após o inicio da brotação, em 16 folhas de cada planta com auxilio de uma escala diagramática. A curva de progresso da doença para cada um dos genótipos foi ajustada ao modelo logístico, já que a severidade observada correspondeu ao modelo e foi confirmada pela coerência entre os pontos estimados e pelo resíduo. Foi verificado que os genótipos FlordaPrince e Premier apresentaram as maiores taxas (0,329) de progresso, enquanto que Douradão a menor (0,223). Verificou-se que o genótipo Dourado 1 apresentou o pico máximo da severidade com 10,5% e que Granada teve o menor acúmulo da doença com 4,5%. Os genótipos de pessegueiro apresentaram diferentes comportamentos do progresso temporal ao chumbinho do pessegueiro.

RESUMO O objetivo deste trabalho foi avaliar o efeito dos óleos essenciais (OEs) de Cymbopogon sp. (Critonela - CI) e Cymbopogon citratus (Capim limão - CL) na redução da pinta bacteriana (Pseudomonas syringae pv. tomato- Pst) e na ativação de algumas respostas bioquímicas de defesa em tomateiro. Foi realizado um teste in vitro para avaliar a presença ou ausência do halo de inibição de Pst pelos OEs, um experimento in vivo para avaliar a melhor concentração desses dois óleos para o controle da pinta bacteriana e um experimento para avaliar o potencial desses óleos e do acibenzolar-S-metil na ativação de algumas respostas bioquímicas em planta de tomate (cv. Santa Cruz). Halos de inibição foram observados para os OEs de CI e CLa partir da concentração de 1%.Os óleos essenciais de CI a uma concentração de 2.000 µL L-1 e CL na concentração de 1.500 µL L-1, bem como o ASM 0,2g L-1 foram eficientes no controle da pinta bacteriana quando aplicados em uma única vez sete dias antes da inoculação do patógeno. O óleo essencial de CI e o ASM conferiram capacidade parcial de proteção em plantas de tomateiro desafiadas por Pst. Os óleos e o ASM também promoveram um aumento na quantidade de fenol total e lignificação da parede celular. Portanto por meio dos resultados obtidos neste trabalho foi demonstrado que existe um potencial uso de OEs no controle da pinta bacteriana do tomateiro, evidenciando a indução de resistência como o principal modo de ação atuante.
Progresso do míldio da cebola sob diferentes regimes de pulverização

Published: September 2017

RESUMO O míldio da cebola é controlado por meio de pulverizações foliares com agrotóxicos seguindo um calendário fixo, sem considerar o progresso da doença. O regime de pulverização baseado em um sistema de previsão pode predizer seu progresso e com isso possibilitar a redução do número de pulverizações e maximizar o controle da doença. Regimes de pulverização foram baseados no sistema de Wallin (1962) com valores de severidade (VDS) acumulado de 6, 8, 10 e 12 comparados ao controle padrão (intervalo de pulverizações de 5 e 7 dias) nas safras agrícolas de 2014 e 2015. Com o objetivo de avaliar o progresso do míldio sob os diferentes regimes de pulverização foi aplicada a técnica de modelagem estatística conhecida por modelos mistos. Estes modelos não incluem apenas os efeitos fixos, mas também os efeitos aleatórios para cada um dos indivíduos da população em estudo. A severidade acumulada do míldio em função do tempo, nos seis regimes de pulverização foi calibrada com um modelo Gompertz ajustado pelo modelo misto e o efeito aleatório ajustado à assíntota superior. Este parâmetro representa o potencial de severidade da doença para cada um dos tratamentos. Como resultado da calibração do modelo, o tratamento com regime de pulverização com VDS 12 com sete pulverizações em ambos os anos não diferiu no controle e na produtividade do sistema convencional utilizado pelo produtor com a vantagem de reduzir o número de pulverizações e com a mesma eficiência do controle.

RESUMO O nematoide das lesões radiculares, Pratylenchus brachyurus, têm causado significativas perdas na cultura da soja, sobretudo, em regiões do Centro-oeste do Brasil. Em função da atual importância deste nematoide em áreas de cultivo de soja e pela pouca disponibilidade de genótipos resistentes no mercado brasileiro, este experimento foi conduzido em casa de vegetação com o objetivo de avaliar a reação de oito cultivares de soja (‘CD 202’; ‘CD 215’; ‘CD 239’; ‘CD 226 RR’; ‘CD 231 RR’; ‘CD 235 RR’; ‘BRS 1841 e ‘BRS 283’) a P. brachyurus. O delineamento experimental foi inteiramente casualizado com oito repetições. A densidade populacional inicial (Pi) utilizada foi de 200 espécimes/planta. A população final (Pf) foi obtida por meio da extração dos nematoides do substrato e das raízes e quantificadas 90 dias após a inoculação. Todas as cultivares de soja foram suscetíveis a P. brachyurus, porém em diferentes graus, FR entre 1,24 e 2,80.
