White blood cells of peripheral blood with ConA-positive glycotopes in patients with chronic leukemia
Authors: Maslak G. S.
Published: May 2016

141 Tumor growth progression of blood cells occurs due to changes in their genetic apparatus, which affects not only the cells morphological characteristics, but also their functional activity which to a greater extent depends on the membrane surface structures, a significant part of which is of glycoprotein nature. Complex type N-glycans are components of surface glycoproteins in the most of leukocytes. Thus, the study of changes in carbohydrate determinants of glycoproteins on the surface of leucocytes in tumorigenesis can help to reveal the mechanisms of this process. The aim of our study was to investigate the monocytes and granulocytes cytoplasmic membrane N-glycosylation in patients with chronic leukemia. The object of the study were blood cells of patients with chronic lymphocytic leukemia (n = 12) and polycythemia vera (n = 15) aged 58–66 years. Healthy hematologic volunteers (n = 15) aged 55 to 65 years were in the control group. N-glycan exposure on monocytes and granulocytes was investigated by flow cytometer Beckman Сoulter EPICS with Canavalia ensiformis lectin – Con A conjugated with fluorescent labels. The number of dead cells was monitored by means of binding them with propidium iodide. The result has been analyzed with FC Express. According to our data, levels of ConA-positive monocytes and granulocytes were 9,9 ± 1,0% and 32,7 ± 3,2%, respectively, in peripheral blood of healthy persons. The level of ConA-positive monocytes decreased to 31,0 ± 2,3% and the number of ConA-binding granulocytes increased to 66,7 ± 3,8% in patients with chronic lymphocytic leukemia compared with the norm. The number of ConA-positive monocytes decreased 3.3 times, and the level of granulocytes interacting with Canavalia ensiformis lectin slightly increased relative to control in polycythemia vera patients. There is significant increase in Con A-positive epitopes on granulocytes in patients with chronic lymphocytic leukemia and polycythemia vera compared with the control group, and absence of any difference in Con A-positive epitopes on monocytes. 100 times increase of the number of ConA-binding glycotopes is observed on the surface of granulocytes in peripheral blood of patients with polycythemia vera, and 3,3 times increase in patients with chronic lymphocytic leukemia, which may serve as an additional marker for the diagnosing these diseases.

Authors: Komshuk T. S.
Published: May 2016

This article presents, based on the example of morphometric study of magnetic resonance tomograms of persons of various ages, the complex of vital characteristics of the cerebrospinal system of the brain in adolescents. The study tested gender characteristics and inter hemispheric asymmetry of the analyzed indexes. An asymmetry of anatomical structures of the right and left hemispheres with the tendency to increase in their sizes in the right hemisphere was found both for males and for females. Females had some age differences in the longitudinal dimension of the III ventricle (this index was lower in older females), the width and index of the IV ventricle was significantly lower in the 18 and 20 year old girls. Objective and methods. The research was conducted on the base of the radiation diagnosis department of Rivne Regional Clinical Hospital on the CT scan General Electric Healthcare Signa MRI 1.5 T and in the office of magnetic resonance imaging of Lutsk City Clinical Hospital on the CT scan Signa Profile Ce Medical System – 1,5 Tl in standard anatomic planes (sagittal, frontal andaxial). Measurements were carried out in persons without visual signs of organic lesions of the brain and skull. Analysis was made of 11 tomograms (males 17–21 years old – 6 persons, females 16–20 years old – 5 persons). In comparing pairs of parameters (of lateral ventricles) the factor of asymmetry was calculated, which is equal to the difference between the right and left lateral ventricles divided by the sum of right and left ventricles indexes (%). The results were processed by methods of descriptional statistics. In young males of this age group a significant increase in the following indicators was identified: the length of the anterior horn of the lateral ventricle on the right side, the length of the body of the lateral ventricle on both sides and the height of the III ventricle. Females had significantly increases in the following parameters: the width of the anterior horn of the lateral ventricle on the right side and the width of the posterior horn of the lateral ventricle on the left side. Consequently, in male adoles cents a parallelism in the formation of various structures of the ventricular system was traced. Since this is a single system, morphological and functional connections between its different components are stored. Mathematical analysis of the values of the structures of ventricular system in females characterize a hormonal influence on its development in adolescents. We can assume that organs which are the part of the circumventricular system (subcommisural organ, subfornical organ, median rise etc.), definitely have the character of anatomical connections between these components. Their functional unity in maintaining the homeostasis of the body is undeniable.
Biotechnological charactheristic of catheterized urinary tract as flow system

Published: May 2016

It is well known that the ureter of mammals and man works as a flow system that normally remains uninfected. In biotechnology flow systems are used to produce microbial mass on orders greater than when grown in laboratory and industrial periodic cultures. Therefore, these systems are used in the microbiological industry. But there ina flow systems one can observe a growth in microbial populations, the patterns of which can be fruitful in studying the process of catheter-associated urinary tract infections. The main factors are the speed of propagation and speed of flow, and their variation in conditions of the catheterized urinary tract, which determines the magnification factor of microbial infection. In this lies the general biological need to study them from a biotechnology perspective. Hence the question arises – why are there changes in the flow system of the urinary tract during catheterization, which contribute to the reproduction of opportunistic microorganisms, as a factor of infection? In the study of the biological properties of agents of catheter-associated infections this issue has not attracted sufficient attention from researchers. In view of the above, the purpose of our study was to establish patterns of population growth of agents of urinary tract infections on the model of the yeast fungus species Candida albicans (C.P. Robin) Berkhout, 1923 in the catheterized human urinary tract, treated as a flow system. The results of the research show that the emergence of catheter-associated urinary tract infections is a regularity inherent throughout the flow system. It was proved that with the model C. albicans, bacteria in urine multiply faster than in the medium Saburo. The study established that one of the factors leading to catheter-associated urinary tract infections is the persistent presence of urine deposits around the head of the catheter in the bladder, which provides bacteria with sufficient conditions for reproduction and where bacteria cannot be eliminated by urine flow. When the pathogen enters and reproduces in the bladder, the latter is a reservoir of infection like a "royal culture", with a gradual overgrowth in the catheter of yeast fungi of the species C. albicans. These data suggest that the mechanism of strengthening catheter-associated urinary tract infections are the formation of biofilms by microorganisms around the catheter head and on its surfaces. It is recommended to further improve the design of urinal catheters in such a way that ensures the complete emptying of the bladder and avoidance of urethral reflux.

Published: May 2016

Introduction: The diagnostic algorithm of primary aldosteronism is burdened with uncertainties and, recently, it has been suggested that the sensitivity of the aldosterone/renin ratio used as a screening test – based on the suppression aldosterone – is low. Aim: The primary aim was to test the accuracy of aldosterone/renin ratio. Method: In a retrospective analysis of 309 hypertensive patients supine and ambulatory aldosterone levels were independently examined. Results: Aldosterone/renin ratio was elevated in 99 patients of whom 31 exhibited elevated supine aldosterone, as well. In 34 cases supine aldosterone was increased without elevation of the aldosterone/renin ratio. However, only 3 of them had concomitant low renin levels indicating that primary aldosteronism could not be ruled out. Abnormally increased renin was found in 69 patients, but only 59% of them had increased aldosterone level. Conclusion: Sensitivity of aldosterone/renin ratio is high (91%) if used only in justified cases. Orv. Hetil., 2016, 157(21), 830–835.

Introduction: The analytic and family therapeutic theories connected to the topic of stutter have to be actualized. Aim: The aim of this work was to point out connections which originate from the instinct of frustrated clinging, however, these can be interpretated in new ways these days. Method: Two questionnaires in 48 subjects suffering from stutter were used; Rosenberg’s Self-Esteem Scale measured the children’s self representation, while the Multidimensional Anxiety Scale for Children measured the degree of their anxiety. At first the subjects had to anwser the questions as themselves, for the second time they had to anwser as an ordinary person without a speech disorder. Results: The hypothesis of the authors was verified: stutterers attributed a significant role to the speech disorder of the subjects in connection with their self-esteem. According to this a significant amount of their anxiety is based on their deficit. An unexpected result was that girls and boys estimated ordinary people’s level of anxiety similarly. There was no significant difference between boys and girls regarding the level of other’s self-esteem. Conclusions: Based on the thesis of evolutionary psychology, the adequate use of speech is more important to women who have a connecting role in the family. This results that they see stutter as a major problem. Orv. Hetil., 2016, 157(21), 825–829.

Published: May 2016

In many developed countries the prevalence of venous disorders and its consequences are higher than that of arterial diseases. Thus it is very important to understand the exact physiological and pathophysiological function of small veins and their control mechanisms. Small veins and venules have an important role in the regulation of capillary fluid exchange, as well as return of the venous blood into the heart. However, there is only limited knowledge available regarding the role of local mechanisms controlling the vasomotor tone and diameter of small veins. In the last decade the authors focused on the elucidation of these mechanisms in isolated skeletal muscle venules of rats. Their results suggest that the tone of small veins is controlled by the integration of several mechanisms, activated by the intraluminal pressure and flow/wall shear stress, in addition to numerous local mediators synthesized and released from the smooth muscle and endothelium. These mechanisms are involved – in a complex manner – in the control of postcapillary resistance, thus regulation of tissue blood supply, venous return and consequently in the modulation of the cardiac output, as well.

Vestibular migraine: diagnosis challenges and need for targeted treatment
Authors: Barbosa Felipe , Villa Thaís Rodrigues
Published: May 2016

ABSTRACT Approximately 1% of the general population suffers from vestibular migraine. Despite the recently published diagnostic criteria, it is still underdiagnosed condition. The exact neural mechanisms of vestibular migraine are still unclear, but the variability of symptoms and clinical findings both during and between attacks suggests an important interaction between trigeminal and vestibular systems. Vestibular migraine often begins several years after typical migraine and has a variable clinical presentation. In vestibular migraine patients, the neurological and neurotological examination is mostly normal and the diagnosis will be based in the patient clinical history. Treatment trials that specialize on vestibular migraine are scarce and therapeutic recommendations are based on migraine guidelines. Controlled studies on the efficacy of pharmacologic interventions in the treatment of vestibular migraine should be performed.

ABSTRACT Objective To evaluate the intercarotid distance (ICD) of patients with pituitary macroadenoma and compare to heatlhy controls. Method We retrospectively reviewed contrast-enhanced MRI images from twenty consecutive patients diagnosed with non-functioning pituitary macroadenoma, measured the ICD at two different levels (petrous segment – ICD1 and horizontal cavernous segment – ICD2) and compared to twenty paired controls. Results There was no statistically significant difference of the mean ICD1 between the groups and subgroups. For the ICD2 there was statistically significant difference between the case and controls. However, there was no significant difference between the patients with smaller adenomas and the controls. In contrast, the patients with giant adenomas showed statistically significantly higher ICD2 than the controls. Conclusion The ICD at the horizontal segment of the cavernous carotid tends to be wider in patients with giant pituitary adenomas than in healthy individuals or patients with smaller adenomas.

ABSTRACT Objective To describe and analyze cognitive aspects in patients with chronic pain and a control group without pain. Method A case-control study was conducted on 45 patients with chronic pain and on 45 control subjects. Data including pain diagnosis, comorbidities and medication used, were evaluated. Cognitive tests, such as the Montreal Cognitive Assessment (MoCA), Verbal Fluency Test, Clock Drawing Test and Stroop Test, were applied. Results Patients with chronic pain showed a poorer performance, as shown by the scores of the MoCA test (p < 0.002), Verbal Fluency Test (p < 0.001), Clock Drawing Test (p = 0.022) and Stroop Test (p < 0.000). Chronic pain variable (p = 0.015, linear regression model) was an independent factor for results obtained with the MoCA. Conclusion Patients with chronic pain showed a poorer performance in a brief screening test for cognitive impairment not related to confounding variables, as comorbidities and pain-medication use.
Visión comprensiva y crítica de los modelos conceptuales sobre acceso a servicios de salud, 1970-2013
Authors: Arrivillaga Marcela , Borrero Yadira Eugenia
Published: May 2016

Resumen: Este estudio tuvo como objetivo analizar críticamente los modelos conceptuales sobre acceso a servicios de salud, descritos en la literatura entre 1970 y 2013. Se realizó una revisión sistemática de publicaciones empíricas y teóricas que conceptualizaron el acceso a servicios de salud de manera explícita. Se revisaron 25 publicaciones que respondían a los objetivos del estudio. El análisis se realizó utilizando una matriz que contenía la lógica del modelo conceptual y su descripción. Los resultados se clasificaron en cinco categorías: (i) acceso a servicios de salud en la lógica de los "mínimos decentes", (ii) de mercado, (iii) de factores y multicausalidad, (iv) de necesidades y (v) de justicia social y derecho a la salud. El estudio concluye que ha sido dominante en la literatura el concepto de acceso desde la lógica de mercado de servicios de atención médica, articulada con la lógica de factores y multicausalidad. Por el contrario, no se encontró ningún modelo conceptual de acceso a servicios de salud, basado explícitamente en la justicia sanitaria y el derecho a la salud.

Published: May 2016

RESUMO O presente estudo consiste de uma revisão sistemática de estudos longitudinais que investigaram a associação entre bullying escolar e conduta infracional na adolescência e criminosa na idade adulta. Realizou-se uma busca bibliográfica em cinco bases de dados internacionais (ERIC, LILACS, Scopus, PsycINFO e Web of Science) e uma biblioteca eletrônica nacional (Scielo). Foram selecionados 13 estudos que atenderam aos critérios de inclusão. A maioria dos trabalhos encontrou associação estatisticamente significativa entre bullying e cometimento de atos contrários à lei por adolescentes e adultos. Em alguns deles, a associação permaneceu significativa após o controle de outros fatores de risco na infância, sinalizando, assim, ser o bullying um fator de risco independente. Isso reforça a necessidade de se prevenir e enfrentar precocemente o bullying escolar.

RESUMO Este estudo teve por objetivo delimitar o itinerário terapêutico - busca por cuidados à saúde, diagnóstico e tratamento - percorrido por mães cujos filhos foram diagnosticados com anorexia nervosa (AN). Trata-se de estudo do tipo exploratório, descritivo e transversal, no enfoque qualitativo de pesquisa. Para a coleta de dados, foram realizadas entrevistas semiestruturadas. A análise de conteúdo temática foi utilizada como estratégia de organização dos dados. Os resultados apontaram diversas barreiras no acesso a serviços especializados para o tratamento da AN. O limitado conhecimento dos profissionais acerca dessa psicopatologia retarda o diagnóstico, o que tem consequências negativas para o prognóstico. O conhecimento produzido sobre a trajetória de busca de ajuda para o problema pode contribuir para aprimorar a oferta e qualificação dos cuidados oferecidos.
O Naturalismo Biológico de Searle e a Relação Mente-cérebro
Authors: Lyra Carlos Eduardo de Sousa , Mograbi Gabriel José Corrêa , El-Hani Charbel Niño
Published: May 2016

RESUMO Apresentamos o 'naturalismo biológico' de John Searle enquanto possível referencial filosófico para um estudo da mente em diálogo com a neurociência contemporânea. O método utilizado baseia-se em uma revisão crítica e sistemática das principais obras de John Searle sobre a consciência e o problema mente-corpo, com eventuais consultas a outros autores. Nosso objetivo principal é demonstrar que a resolução apresentada por Searle ao problema mente-corpo acaba por introduzir um dualismo de propriedades ou de perspectivas que não resolve, de fato, o problema. Apesar disso, reconhecemos a posição apresentada por Searle como um avanço importante na tentativa de enfrentar a tradição cartesiana e alguns de seus caudatários contemporâneos.

Published: May 2016

ABSTRACT: Three commercial kits of One-Step RT-qPCR were evaluated for the molecular diagnosis of Canine Distemper Virus. Using the kit that showed better performance, two systems of Real-time RT-PCR (RT-qPCR) assays were tested and compared for analytical sensitivity to Canine Distemper Virus RNA detection: a One-Step RT-qPCR (system A) and a One-Step RT-qPCR combined with NESTED-qPCR (system B). Limits of detection for both systems were determined using a serial dilution of Canine Distemper Virus synthetic RNA or a positive urine sample. In addition, the same urine sample was tested using samples with prior centrifugation or ultracentrifugation. Commercial kits of One-Step RT-qPCR assays detected canine distemper virus RNA in 10 (100%) urine samples from symptomatic animals tested. The One-Step RT-qPCR kit that showed better results was used to evaluate the analytical sensitivity of the A and B systems. Limit of detection using synthetic RNA for the system A was 11 RNA copies µL-1 and 110 RNA copies µl-1 for first round System B. The second round of the NESTED-qPCR for System B had a limit of detection of 11 copies µl-1. Relationship between Ct values and RNA concentration was linear. The RNA extracted from the urine dilutions was detected in dilutions of 10-3 and10-2 by System A and B respectively. Urine centrifugation increased the analytical sensitivity of the test and proved to be useful for routine diagnostics. The One-Step RT-qPCR is a fast, sensitive and speciﬁc method for canine distemper routine diagnosis and research projects that require sensitive and quantitative methodology.

ABSTRACT: This research aimed to determine incidence of Toxoplama gondii infection in Corriedale sheep in southern Brazil during pregnancy and the extent of associated losses. Blood samples were collected from 411 Corriedale sheep in two flocks at different locations in the state of Rio Grande do Sul (Brazil). Presence of T. gondii was diagnosed by the Indirect Fluorescent Antibody Technique (IFAT). Seroprevalence of T. gondii during pre-mating was 20.2%, with no significant difference between the two flocks studied. Infection by T. gondii was influenced by ewes'age (P≤0.05). The pre-mating seroprevalence did not influence either returning to estrus or pregnancy rates. Weaning rate was significantly higher in pre-positive dams compared to negative ones (87.9 and 74.1%, respectively - P<0.05). The incidence of seroconversion was 16.5% (54/328). In seroconverted ewes, a high rate of return to estrus was observed (P≤0.05). The incidence of toxoplasmosis suggests production losses equivalent to 1.87% per year, in this system production. In addition, toxoplasmosis decreased the number of lambs per ewe. Therefore, to improve livestock performance, T. gondii infection should be monitored and controlled in the studied area.

ABSTRACT: This study aimed to evaluate aspects of reproductive phenology, yield components and seed quality of the B4 genotype of Brachiaria brizantha in function of nitrogen doses applied at pre-flowering. The experiment was carried out at Embrapa Beef Cattle, in a randomized block design, with seeding density of 2.59kg SPV ha-1 in the first year, in free growth plants. Urea was applied at pre-flowering at doses of 0, 25, 50, 75, 100, 125 and 150kg ha-1. The reproductive cycle of the plant lasts 225 days, with late flowering. N doses influenced the following characteristics: number of fully expanded inflorescences, percentage of dry matter, dry biomass, number of spikelets per raceme, seed yield, weight of a thousand seeds, germination, germination speed index, viability and germination at 10 months after harvest. The maximum yield of pure seed was 144.8kg ha-1 for 50kg ha-1 N, with maximum biological potential, based on components of seed yield of 456.27kg ha-1. Seeds presented high dormancy and reduced physiological quality in higher N doses.

Resumo Este artigo empírico tem como principal objetivo identificar como a inovação contribui para a conquista de vantagens competitivas numa firma produtora de suco e vinho orgânicos. Para isso, foram apresentados referenciais teóricos a respeito de inovação e vantagem competitiva. Para atingir o objetivo, metodologicamente, o estudo utilizou a abordagem exploratória qualitativa, por meio de entrevistas em profundidade realizadas com cinco gestores da firma. Os resultados permitiram analisar a introdução de inovações, especificamente de processo e de produto, refletindo-se na conquista de vantagens competitivas. Embora o segmento de alimentos orgânicos ainda tenha pequena representatividade, as perspectivas mostram, para os próximos anos, aumento na participação no total dos alimentos consumidos no país e no mundo.
Teatro, liberdade e repressão nos Festivais de Inverno de Ouro Preto, 1967-1979
Authors: Kaminski Leon Frederico
Published: May 2016

Resumo O Festival de Inverno de Ouro Preto, criado em 1967, foi uma das maiores promoções culturais do país na década de 1970. O evento oferecia uma diversidade de atividades, como cursos, concertos, exposições de arte e espetáculos teatrais, atraindo milhares de pessoas à cidade histórica. Em plena ditadura militar, era visto como espaço de liberdade de criação e experimentação artística, mantendo diálogo intenso com as propostas estéticas de vanguarda. No campo das artes cênicas, grupos como Corpo, Giramundo e Oficcina Multimédia tiveram gênese ligada ao evento. Temos como objetivo analisar o Festival de Inverno, entre 1967 e 1979, enquanto espaço de trocas culturais e de experimentações estéticas que possibilitaram a criação cênica para além das fronteiras disciplinares. Discutiremos também as ambiguidades e contradições do evento em relação às diferentes políticas do governo ditatorial, que ao mesmo tempo fomentava e reprimia a cultura.
Discriminação e abandono de recém-nascidos mestiços na América Portuguesa: Os exemplos de Mariana, Vila Rica e Recife
Authors: Franco Renato
Published: May 2016

Resumo O financiamento da criação de recém-nascidos abandonados pelos pais nas ruas das localidades portuguesas foi regulamentado pelas Ordenações Manuelinas (1512) e frequentemente constituía um tema controverso porque era uma iniciativa onerosa, que recaía sobre os cofres municipais e, no limite, sobre a população local, por meio de impostos (fintas) lançados pelo termo. Quando passou a ser obrigação legal, uma vez posta em prática, os concelhos encarregavam-se de cuidar de todos os expostos da localidade. Este artigo analisa os casos de Mariana e Vila Rica, em Minas Gerais, e Recife, em Pernambuco, onde foi regulamentado o financiamento da criação dos enjeitados. Contudo, essa forma de caridade, típica das regiões católicas no Ocidente, passaria por inovações frente à presença de populações miscigenadas na América portuguesa. Nos três exemplos estudados, as autoridades propuseram restringir o público de auxiliados a partir de critérios étnicos, estabelecendo, assim, novas fronteiras das noções de caridade, pobreza e assistência.
Cruzes e feitiços: Identidades e trocas culturais nas práticas fúnebres em Angola
Authors: Marzano Andrea
Published: May 2016

Resumo O objetivo deste artigo é refletir, através da análise de jornais e textos literários, sobre práticas, trocas culturais e conflitos nas cerimônias fúnebres em Luanda e arredores entre o final do século XIX e o início do XX. Trabalhamos com três categorias sociais: colonos (metropolitanos e descendentes), filhos da terra (nascidos em Angola que dominavam códigos culturais europeus) e gentio (africanos que, por não dominarem códigos culturais europeus, não tinham acesso aos direitos da cidadania portuguesa e podiam ser sujeitos ao trabalho forçado). Em um contexto de intensificação da presença portuguesa e de subalternização das elites da terra e do gentio, os funerais eram ocasiões privilegiadas de manifestação de diferenças e compartilhamentos. Através das práticas fúnebres, os diversos grupos sociais afirmavam suas identidades e promoviam trocas culturais que gerariam não apenas conflitos e controle, mas também formas híbridas de tratamento da morte, explicitando uma importante característica da cultura urbana luandense.
Relações comerciais e diplomáticas Anglo-africanas durante a expedição ao Níger de 1854
Authors: Gebara Alexsander Lemos de Almeida
Published: May 2016

Resumo O artigo procura compreender a expedição britânica nos rios Niger e Benue em 1854 num contexto de transformação nas relações políticas e econômicas da Grã Bretanha com o interior da África Ocidental. Tal empreendimento ficou marcado pela ausência de mortes por febres tropicais e deixou vários registros, dentre eles relatos de viagem e a correspondência entre seus agentes e o Foreign Office e o Colonial Office que compõe o corpo de fontes deste artigo. Especial atenção é dedicada aos termos e formas das trocas comerciais realizadas com os africanos diretamente ao longo da viagem e às condições nas quais estes relacionamentos foram estabelecidos. Assim, procura-se por um lado, compreender a expedição como parte de um de um processo de ampliação da presença europeia no interior e, por outro lado, refletir sobre as estratégias africanas em diálogo com as transformações econômicas na bacia Atlântica em meados do século XIX.
Cartoneros, espacio público y estrategias de supervivencia. Mar del Plata, Argentina, 1990-2014
Authors: Paiva Verónica , Banfi Juan
Published: May 2016

Durante la década de 1990 se implementaron en Argentina políticas neoliberales que incrementaron el desempleo y la pobreza. En ese contexto una parte de la población -que ya era pobre - se empobreció aún más y recurrió a la recolección informal de residuos como estrategia de supervivencia. En esa situación el espacio público se convirtió no sólo en un lugar de tránsito sino de reproducción de las condiciones de vida, y, dado que la actividad se realiza a la vista de todos, debieron implementar "fachadas" para acreditarse frente a los demás. Por ello el objetivo de este artículo es analizar las de interacciones que entablan con otros actores y cómo utilizan el espacio público los recolectores informales en la ciudad de Mar del Plata, una ciudad balnearia e intermedia de la Argentina. Las fuentes y la metodología usadas para realizar la investigación fueron la entrevista en profundidad y la observación, además de periódicos de la Ciudad. Los resultados más importantes versan sobre las técnicas que utilizan para acreditarse frente a sí mismos y frente a los demás.
Effects of a small natural barrier on the spatial distribution of the fish assemblage in the Verde River, Upper Paraná River Basin,Brazil

Abstract Geographical barriers influence species distribution and play an important role in the segregation of fish assemblages. The present study aims to test the influence of a small natural barrier on the spatial distribution of fish species in the Verde River, Upper Paraná River Basin, Brazil, considering two biotopes: upstream and downstream of the Branca Waterfall. We observed the highest species richness downstream of the Branca Waterfall, which also had the highest number of exclusive species. Richness, evenness, and abundance varied significantly among biotopes. The composition and structure of the fish assemblage differed between biotopes, which were characterized by different indicator species, mainly downstream of the Branca Waterfall. Physical and chemical variables and geographical distance between sites were not responsible for the differences observed. Hence, the present study shows that small barriers can also be crucial in structuring fish fauna and play a key role in the segregation of fish assemblages.

Abstract Phenolic compounds are a group of plant secondary metabolites known to have a variety of bioactivities, including the ability to function as antioxidants. Because of the side effects of the use of synthetic substances, the search for natural and less toxic compounds has increased significantly. This study was designed to evaluate the antioxidant activity and phenol content of hexane, ethyl acetate, and aqueous extracts of the bark (suber) and stems as well as the young and mature leaves of Blepharocalyx salicifolius. The extracts were obtained by extraction with organic solvents and subsequent fractionation by chromatographic partition coefficient. Preliminary tests for the presence of antioxidants were performed using bioautography in thin-layer chromatography. The antioxidant activity of the extracts was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, and the phenol content of the extracts was quantified using the Folin-Ciocalteu technique. The results showed that 9 of the 12 extracts evaluated displayed very strong antioxidant activity and three displayed moderate activity. Aqueous extracts of the young leaves and bark and the ethyl acetate extract of the young leaves showed the highest levels of antioxidant activity and total phenolic content (TPC). A correlation was observed between TPC and antioxidant activity index (AAI) with a correlation coefficient (r2) of 0.7999. Thus, the high phenol content of B. salicifolius extracts and its correlation with antioxidant activity provide substrates for further studies.

Abstract The goal of this study is to analyze the floristic patterns and the structure of disturbed and undisturbed upland forests, in Permanent Preservation Areas (PPAs) along the Moju river, in the Brazilian state of Pará. Trees with a diameter equal to or larger than 10cm at 1.30m from the ground (DBH) ≥10cm were analyzed for the upper stratum. For the middle stratum, individuals with DBH between 4.99 and 9.99cm were sampled. Forty-five families and 221 species were found in disturbed forests, and 43 families and 208 species in undisturbed forests. Floristic similarity was high between strata and between forest types, with values above 50%. Similarity was highest between middle strata. The most species-abundant families in undisturbed forests were Fabaceae, Sapotaceae, Chrysobalanaceae and Myrtaceae; the species with the highest density there were Eschweilera grandiflora, Licania sclerophylla and Zygia cauliflora. In disturbed forests, the dominant families were Fabaceae, Sapotaceae, Lecythidaceae and Melastomataceae. The Shannon-Wiener diversity index was 3.21 for undisturbed forests and 2.85 for disturbed forests. Non-metric multidimensional scaling (MDS) analysis did not group the forests by their floristic composition in both upper and middle strata. Overall, the PPA forests along the Moju river, even if disturbed, did not show major floristic changes but substantially change their structural characteristics.
