ABSTRACT: Neto, FR, Dorneles, JR, Luna, RM, Spina, MA, Gonçalves, CW, and Gomes Costa, RR. Performance differences between the arched and flat bench press in beginner and experienced Paralympic powerlifters. J Strength Cond Res 36(7): 1936-1943, 2022-The present study aimed to verify the differences of the total load, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell between the arched and flat techniques of the bench press in beginner (BG) and experienced (EG) Paralympic powerlifters. Twenty beginners (age: 34.4 years; experience: 3.3 months) and 23 experienced (age: 35.5 years; experience: 9.8 months) Paralympic powerlifters were selected from a Rehabilitation Hospital Network and a Paralympic sports center. Subjects were assessed in the one-maximum repetition test of the bench press exercise using the flat and arched bench press techniques (48-72-hour interval between sessions). Maximum strength, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell were measured to compare the techniques and the groups. The total load corrected with the Haleczko formula was significantly higher in EG compared with BG (∆ = 21.1%; effect sizes [ES] = 0.39, p ≤ 0.05). There were no significant differences for all analyzed outcomes comparing the arched and flat techniques. During the eccentric phase of the bench press, all assessed differences ranged from -16.6 to 23.1% and presented ES of trivial to moderate. On the concentric phase, the assessed differences ranged from -20.7 to 13.9% and presented ES of trivial to moderate. The total load, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell were not significantly different between the arched and flat techniques for experienced and beginner powerlifting athletes during both the eccentric and concentric phase of the movement. However, further analyses are essential to determine the best technique for athletes.

Scorpions are a mesodiverse and nocturnal group of arachnids inhabiting most biomes worldwide. Different species of scorpions have divergent adaptations to the substrate they live in, but most of them share an intriguing characteristic: their exoskeleton contains fluorophores that emit blue-greenish fluorescence under ultraviolet radiation. Although there are some reports in the literature on the study of fluorescence in scorpions, the biological functionality of this light emission is currently unknown and is under debate. In this work, the properties of emission from the scorpion's exoskeleton are studied by means of digitally processed photographs taken of living specimens under ultraviolet illumination and complemented with standard spectroscopic measurements of emission and excitation spectra. With the aim of identifying possible correlations between the fluorescence, the characteristics color of the exoskeleton and the biology of the scorpions, 4 families, 9 genera and 24 species were studied. Our results suggest that the intensity of fluorescence is heterogeneous throughout the scorpion's exoskeleton studied here in such a way that pedipalps and metasomal segments fluoresce more intensely than the mesosomal segments. The spectrum of fluorescence across species is practically identical, suggesting that the same fluorophores are present in their exoskeletons. However, the fluorescence intensity emitted by each species varies according to their characteristic color (associated with the exoskeleton optical reflectance). Since the coloration of the exoskeleton is determined by the concentration of melanin and other pigments according to the substrate where scorpions live in, we conclude by suggesting that fluorescence may correlate directly to the ecomorphotype of the scorpions.

ABSTRACTIntroduction:The medical congresses are an efficient way, although restricted, to expose the scientific production of a particular specialty. However, the number of complete articles published resulting from papers presented at congresses and published as abstracts is much lower than the number of papers presented during the meetings.Objective:Scale the number of complete articles published and indexed in online databases, from 2012 to January 2015, originally presented at the 28th Congresso Brasileiro de Patologia (28th Brazilian Congress of Pathology) and the 28th Congreso de la Sociedad Latinoamericana de Patología (28th Latin American Society of Pathology Congress).Material and method:In the meetings mentioned 701 papers were presented and their abstracts published in the congresses annals. An observational retrospective study was conducted consulting the following biomedical databases: Scientific Electronic Library Online (Scielo) and US National Library of Medicine on the National Institutes of Health (PubMed), with the help of the Google search engine, based on the article title and the list of authors.Results:From 701 studies analyzed, 635 (90.6%) were from Brazilian institutions, 60 (8.6%) from foreign institutions, and six (0.8%) did not identified their home institutions. There were found 63 (8.8%) complete articles published and indexed to consulted databases. International journals were the destination of 38 (60.3%) publications.Conclusion:The number of complete articles published in Pathology area arising from the papers presented in the studied meetings in the first three years after the meetings is relatively small. This number is low compared with other international conferences; however, it is higher than some Brazilian medical congresses analyzed in similar studies.
RESUMOIntrodução:Os congressos médicos são um meio eficiente, embora restrito, de expor a produção científica de uma determinada especialidade. Entretanto, o número de artigos completos publicados resultantes dos trabalhos apresentados em congressos e publicados como resumos é muito inferior ao número dos trabalhos apresentados durante os eventos.Objetivo:Dimensionar o número de artigos completos publicados e indexados em bases de dados virtuais, no período de 2012 a janeiro de 2015, apresentados originalmente no XXVIII Congresso Brasileiro de Patologia e no XXVIII Congreso de La Sociedade Latinoamericana de Patología.Material e método:Nos eventos mencionados, foram apresentados 701 trabalhos e seus resumos publicados nos anais do congresso. Efetuou-se um estudo retrospectivo observacional consultando as seguintes bases de dados biomédicas: Scientific Electronic Library Online (Scielo) e US National Library of Medicine do National Institutes of Health (PubMed), com o auxílio do buscador Google, tomando por base o título do trabalho e a lista de autores.Resultados:Dos 701 trabalhos analisados, 635 (90,6%) eram originados de instituições brasileiras, 60 (8,6%), de instituições estrangeiras e em seis (0,8%) não foram identificadas as instituições de origem. Foram encontrados 63 (8,8%) trabalhos completos publicados e indexados às bases de dados consultadas. As revistas internacionais foram o destino de 38 (60,3%) publicações.Conclusão:É relativamente pequeno o número de artigos completos publicados na área de Patologia, resultantes dos trabalhos apresentados nos eventos estudados, nos três primeiros anos após a realização do evento. Esse número é baixo, quando comparado com o de outros congressos internacionais, contudo, é superior ao de alguns congressos médicos brasileiros analisados em estudos semelhantes.
ABSTRACT
OBJECTIVE: Endothelial colony-forming cells (ECFCs) are a subset of circulating endothelial progenitor cells that are particularly abundant in umbilical cord blood. We sought to determine whether ECFC abundance in cord blood is associated with maternal body-mass index (BMI) in nonpathologic pregnancies. STUDY DESIGN: We measured the level of ECFCs in the cord blood of neonates (n = 27) born from non-obese healthy mothers with nonpathologic pregnancies and examined whether ECFC abundance correlated with maternal BMI. We also examined the effect of maternal BMI on ECFC phenotype and function using angiogenic and vasculogenic assays. RESULTS: We observed variation in ECFC abundance among subjects and found a positive correlation between prepregnancy maternal BMI and ECFC content (r = 0.51, P = .007), which was independent of other obstetric factors. Despite this variation, ECFC phenotype and functionality were deemed normal and highly similar between subjects with maternal BMI <25 kg/m(2) and BMI between 25-30 kg/m(2), including the ability to form vascular networks in vivo. CONCLUSIONS: This study underlines the need to consider maternal BMI as a potential confounding factor for cord blood levels of ECFCs in future comparative studies between healthy and pathologic pregnancies.

A Mueller-Stokes analysis is applied to pure bismuth thin film samples prepared by the laser ablation technique by using a polarimeter with a 632.8 nm continuum wavelength laser. The complex refractive index is determined in the range of 250-1100 nm. Results from the Mueller matrix show the high sensitivity of diattenuation and polarizance parameters as a function of the sample thickness and the incidence angle, except at the pseudo-Brewster angle, where they exhibit the same value. Results show that the knowledge of the polarimetric response, with appropriate incident polarization states, could be used to design photonic Bi-based devices for several applications. Polarization dependence is the result of changes on the surface morphology as a result of the small value of the skin depth.

Determinar la prevalencia de cáncer tiroideo en 100 necropsias de personas fallecidas por causas no tiroideas. Resecar la glándula tiroidea en 100 autopsias de cadáveres cuyo fallecimiento haya sido originado por causas no inherentes a ese órgano. Cada glándula se cortará cada 3 mm a nivel de los polos superiores, inferiores e istmo, obteniendo cortes histológicos que son teñido con hematoxilina y eosina, para su posterior visualización bajo microscopia óptica. Servicio de Anatomía Patológica, Hospital Universitario "Antonio Patricio de Alcalá", Cumaná. La incidencia de las glándulas tiroides con nódulos alcanzó el 35 por ciento, ocupando el carcinoma tiroideo el 4 por ciento de todos los órganos endocrinos estudiados, siendo el más frecuente el carcinoma papilar, seguido del folicular. No se observó diferencia según el sexo y la edad. La ubicación más frecuente fue en el lóbulo izquierdo, presentando un solo foco en todos los casos: la naturaleza histológica de los nódulos no malignos más frecuente fue la hiperplasia nodular, alcanzando el 68,5 por ciento de todos las glándulas con nódulos, continuando en orden los procesos inflamatorios destacándose la tiroiditis crónica con el 8,5 por ciento. El 75 por ciento del cáncer tiroideo está asociado a la hiperplasia nodular. De cada 10 pacientes que fallecen por causa no tiroidea, 3,5 presentarán una lesión nodular. El carcinoma oculto más frecuentemente encontrado es el papilar

Resumo: O atual Sistema de ensino médico no Brasil necessita de uma reformulação. A Cinaem tem nos indicado o caminho a ser trilhado. O Programa de Saúde da Família exige um profissional com perfil diferente do atual. Estamos propondo um tipo de ensino baseado 70% no ambulatório e só 30% no hospital, ao contrário dos dias de hoje. O modelo deve integrar, simultaneamente, a Clínica Médica da criança, do adolescente, do adulto e do idoso. Estamos tentando evitar a fragmentação artificial da Clínica Médica em disciplinas estanques e ensiná-la integrada em módulos. Estabelecemos um limite ao conjunto de conhecimentos que deve ser transmitido ao aluno. O graduado em Medicina deve ser um profissional preparado para diagnosticar e tratar bem 80% das doenças de uma comunidade. Cada uma das turmas de 50 alunos é dividida em seis pequenos grupos de oito estudantes para efeito de seminários e prática ambulatorial, sempre com a orientação de um preceptor. As aulas teóricas de Clínica Médica são ministradas só uma vez por semana. O exame dos docentes é a atividade mais freqüente e soma 15 horas no mesmo período. A promoção da saúde em todos os seus aspectos tem prioridade no curso da Unigranrio. A profissionalização dos preceptores é um dos nossos objetivos.
Abstract: The current medical teaching system in Brazil needs reformulation. CINAEM has shown us the road to follow. The family Health Program requires health care professionals with a different kind of background than the current norm. We propose a kind of teaching in which 70% is based on out-patient care, with the remaining 30% in-hospital, contrary to the prevailing model. The model should simultaneously include Clinical Medicine for children, adolescents, adults, and the elderly. We are attempting to avoid artificial fragmentation of Clinical Medicine in isolated disciplines and to teach trough integrated modules. We establish a limit on the set of knowledge that should be transmitted to students. Graduates in Medicine should be professionals prepared to diagnose and properly treat 80% of the disease in a community. Each class of 50 students is divided into six smaller groups of eight students each for seminars and out-patient practice, oriented by monitors. Theoretical lectures in Clinical Medicine are given only once a week. The most frequent activity is examining patients and takes up 15 hours during the same period. Health promotion with all is its aspects is a course priority at the Unigranrio Shool of Medicine. Professional training of monitors is one of our objectives.
