Resumen Introducción: El tipo de uso del suelo que rodea los remanentes de bosque tropical puede generar cambios en las características de las poblaciones y comunidades vegetales. En consecuencia, puede haber una reducción significativa en los procesos de polinización y dispersión de las diásporas. Por lo tanto, provocando cambios en algunos parámetros de la lluvia de semillas. Objetivo: Caracterizar y comparar la densidad de semillas, la riqueza de especies, la composición florística, el hábito, el síndrome de dispersión y la categoría sucesional de la lluvia de semillas entre fragmentos urbanos y rurales de Mata Atlántica, en las estaciones climáticas del 2015 y 2016. Métodos: Las áreas de estudio se definieron luego del mapeo y cuantificación de las ocupaciones urbanas y rurales alrededor de los remanentes, con base en imágenes satelitales. En cada fragmento se instalaron 36 colectores de 0.25 m2. El material fue recolectado mensualmente durante dos años consecutivos. Resultados: La riqueza de lluvia de semillas fue mayor en el fragmento urbano durante la estación lluviosa en los dos años, mientras que fue similar entre los fragmentos en la estación seca. La densidad de semillas en el fragmento rural fue mayor que en el urbano durante la estación lluviosa; no varió en urbano entre años o entre estaciones; y fue mayor en el fragmento rural en la estación lluviosa del primer año. Hubo una diferencia en la composición florística de la lluvia de semillas entre los fragmentos a lo largo del tiempo. Las variaciones en los atributos funcionales de hábito, síndrome de dispersión y categoría sucesional, fueron explicadas por las variables fragmento, estación y año. Conclusiones: Las diferencias en las características de la lluvia de semillas entre los fragmentos podrían reflejar la heterogeneidad espacial y temporal, debido a los diversos usos del suelo y presiones externas (acciones antropogénicas) presentes en el entorno de los fragmentos de bosque y variación temporal de la precipitación.

Abstract Introduction: The type of land use surrounding the remnants of tropical forest may generate changes in the characteristics of plant populations and communities. Consequently, there may be a significant reduction in processes of pollination and diasporas dispersion. Therefore, causing changes in some parameters of seed rain. Objective: To characterize and compare seed density, species richness, floristic composition, habit, dispersal syndrome, and successional category of seed rain between urban and rural fragments of Atlantic Forest, in the 2015 and 2016 weather seasons. Methods: The study areas were defined after mapping and quantification of urban and rural occupations around the remnants, based on satellite images. In each fragment, were installed 36 collectors of 0.25 m2. The material was collected monthly during two consecutive years. Results: Seed rain richness was higher in the urban fragment during the rainy season in the two years, whereas it was similar between the fragments in the dry season. The seed density in the rural fragment was higher than in the urban during the rainy season; did not vary in urban between years or between seasons; and it was higher in the rural fragment in the rainy season of one year. There was a difference in the floristic composition of the seed rain between the fragments along time. The variations in the functional attributes of habit, dispersal syndrome, and successional category, were explained by the variables fragment, season, and year. Conclusions: Differences in the characteristics of the seed rain between the fragments might reflect the spatial and temporal heterogeneity, due to the diverse uses of the soil and external pressures (anthropogenic actions) present in the surroundings of the forest fragments and temporal variation in precipitation.

RESUMO: Descreve-se um caso de infarto cerebral e meningoencefalite trombótica devido a candidíase em um bezerro de sete meses de idade. A morte ocorreu três dias após o início de apatia, febre e desvio lateral da cabeça para a esquerda. As alterações macroscópicas no cérebro consistiam em assimetria dos hemisférios telencefálicos; o hemisfério direito estava aumentado, causando herniação cerebelar. Uma extensa área vermelha focal foi observada na superfície do lobo occipital direito. Nos cortes transversais do encéfalo fixado, as lesões revelaram áreas extensas, marrom-avermelhadas, moles ou cavitadas, afetando a substância branca e cinzenta desde o nível do tálamo até o cerebelo e comprimindo as estruturas subjacentes. Histologicamente, havia meningoencefalite necrossupurativa multifocal aguda, coalescente, associada a vasculite, congestão, trombose, edema, infarto e hifas fúngicas intralesionais. O diagnóstico de infarto cerebral e meningoencefalite trombótica devido a candidíase foi feito pelas alterações patológicas, coloração e características morfológicas do agente e imuno-histoquímica. O infarto cerebral e meningoencefalite trombótica em bovinos pode resultar de lesões vasculares devido à infecção por Candida sp.; embora incomum, este caso demonstra que a candidíase deve fazer parte de uma lista de diagnósticos diferenciais de lesões cerebrais graves em bovinos.

ABSTRACT: We described a case of cerebral infarction and thrombotic meningoencephalitis due to candidiasis in a seven-month-old calf. The death occurred three days after the onset of apathy, fever, and the head’s lateral deviation to the left. Macroscopic changes in the brain consisted of asymmetry of telencephalic hemispheres; the right hemisphere was enlarged, causing cerebellar herniation. A focally extensive red area was observed on the surface of the right occipital lobe. At cross-sections of the fixed brain, the lesions revealed to be extensive, red-brown, soft or cavitated areas affecting the white and grey matter from the level of the thalamus to the cerebellum and compressing subjacent structures. Histologically, there was acute, coalescent, multifocal necrosupurative meningoencephalitis, associated with vasculitis, congestion, thrombosis, edema, infarction, and intralesional fungal hyphae. The diagnosis of cerebral infarction and thrombotic meningoencephalitis due to candidiasis was made by the pathological changes, the staining and morphological characteristics of the agent, and immunohistochemistry. The cerebral infarction and thrombotic meningoencephalitis in cattle can result from vascular lesions due to infection by Candida sp.; although uncommon, this case demonstrated that candidiasis should be part of a list of differential diagnoses of severe brain injuries in cattle.

ABSTRACT Body mass is known to affect muscle strength and the outcome of some functional tests, so that heavier and taller people will be stronger than lighter and smaller ones. Ratio standard (RS) has been widely used to remove the body mass effect, despite long date criticism due to its inadequacy. Allometry (ALLO), in turn, has been applied as an efficient method for normalizing muscular strength. As the bench press (BP) is a well-recognized strength and conditioning exercise for older adults, the aim of the present study was to verify the influence of body mass on the performance assessment of a group of older men in the BP, by comparing the absolute, RS and ALLO approaches. Sixteen healthy old men (65.5±5.13 years old; 75.42±9.78Kg; 1.73±5.98m; 25.11±2.71 kg/m2; 24.76±4.10 %fat) volunteered to participate in the study. Maximum dynamic load was verified by individual one-repetition maximum (1-RM) tests. Comparisons of means revealed that significant 1-RM difference between lighter (54.9±8.85Kg) and heavier (66.2±8.86Kg) participants was identified only in absolute approach (p<0.05; ES=0.57). RS failed in completely remove the body mass effect, allowing correlation between normalized muscular strength and BM (r=0.23), in contraire of ALLO (r=0.03 and 0.06). Kendall's concordance coefficient revealed an absolute lack of agreement between approaches when compared their respective ordinal classifications (kw=0.003; p>0.05). In line with previous research, ALLO has shown to be the only suitable method to remove adequately the body mass effect and to provide appropriated performance scores for the older men evaluated in this study.

RESUMO Sabe-se que a massa corporal afeta a força muscular e o resultado de alguns testes funcionais, de modo que pessoas mais pesadas e altas serão mais fortes que as mais leves e menores. A razão-padrão (RP) tem sido largamente utilizada para remover o efeito da massa corporal, apesar de críticas conhecidas há muito tempo devido sua inadequação. Alometria (ALO), do contrário, tem sido aplicada como um método eficiente para normalizar a força muscular. Como o supino é um exercício de força e condicionamento bem reconhecido para idosos, o objetivo deste estudo foi verificar a influência da massa corporal sobre a avaliação do desempenho de um grupo de idosos no supino, comparando as abordagens absoluta (AB), RP e ALO. Dezesseis idosos saudáveis (65,5±5,13 anos de idade; 75,42±9,78Kg; 1,73±5,98m; 25,11±2,71 kg/m2; 24,76±4,10 %gordura) se voluntariaram para participar no estudo. A máxima carga dinâmica foi verificada pelos testes de 1 repetição máxima (1RM). Na comparação das médias, a diferença significante do 1RM entre os participantes leves (54,9±8,85Kg) e pesados (66,2±8,86Kg) foi identificada apenas na abordagem ABS (p<0,05; ES=0,57). A RP falhou em remover completamente o efeito da massa corporal, permitindo correlação entre a força muscular e a massa corporal normalizadas (r=0,23), ao contrário da ALO (r=0,23 e 0,06). O coeficiente de Kendall revelou ausência de concordância entre as abordagens quando comparadas as suas respectivas classificações ordinais (kw=0,003; p>0,05). Em linha com pesquisas anteriores, ALO tem se mostrado como o único método viável para remover adequadamente o efeito da MC e para oferecer escores de desempenho mais apropriados para homens idosos, como os avaliados por este estudo.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

ABSTRACT Purpose: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal Methods: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility. Results: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes. Conclusions: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

ABSTRACT The aim of this study was to test two low-level laser therapy protocols by evaluating pain control, swelling and trismus in the postoperative period of lower third molar surgeries. This was a randomized, double-blind, placebo-controlled, crossover trial. Patients presenting two symmetrically impacted mandibular third molars were included. One side was randomly assigned for LLLT applied immediately after surgery (T1) and then after 24 (T2) and 48 hours (T3) (Protocol A). The other side received LLLT applied immediately after surgery and placebo after 24 and 48 hours (Protocol B). LLLT was given by intraoral application (660nm, 5 J/cm2, 10 s, 20 mW, 4 points) followed by extraoral application (789 nm, 30 J/cm2, 20 s, 60 mW, 8 points). The placebo application was similar to that of the experimental side but with laser simulation. The primary outcomes were pain control, swelling and trismus intensity at T1, T2, T3 and 7 days after surgery (T4). Data were analyzed by ANOVA repeated measures and Wilcoxon test (p<.05). The final sample consisted of 21 patients (42 teeth). There were no statistical differences for pain level between protocols A and B over time (p= .909), although the amount of analgesic medication was lower with protocol A at T2 (p=.022). There were no differences in swelling (p=.958) or trismus (p=.837) between the protocols used over time. Both protocols performed similarly for pain control, swelling and trismus. Therefore, for practical reasons, a single laser application in the immediate postoperative period could be indicated for the management of postoperative discomfort in lower third molar surgery.

RESUMO O objetivo deste estudo foi testar dois protocolos de terapia com laser de baixa intensidade (LBI) para controle da dor, edema e trismo no período pós-operatório de cirurgias de terceiro molar inferior. Neste estudo randomizado, duplo-cego, controlado, de boca dividida foram incluídos pacientes que apresentavam os terceiros molares inferiores simetricamente. Um lado foi aleatoriamente designado para receber LBI aplicada imediatamente após a cirurgia (T1) e após 24 (T2) e 48 (T3) horas (Protocolo A). O lado oposto recebeu LBI imediatamente após a cirurgia e placebo após 24 e 48 horas (Protocolo B). A aplicação de LBI foi realizada intraoralmente (660nm, 5 J/cm2, 10 s, 20 mW, 4 pontos), seguida pela aplicação extraoral (789 nm, 30 J/cm2, 20 s, 60 mW, 8 pontos). O efeito do placebo foi similar ao experimental. Os desfechos primários eram dor, edema e intensidade do trismo nos tempos T1, T2, T3 e 7 após a cirurgia (T4). Os dados foram analisados por ANOVA e teste de Wilcoxon (p<.05). A amostra final consistiu de 21 pacientes (43 dentes). Não houve diferença estatística para o nível de dor entre os protocolos A e B ao longo do tempo (p=.909), embora a quantidade de medicação analgésica tenha sido menor com o protocolo A em T2 (p= .022). Não houve diferença para edema (p=.958) ou trismo (p=.837) entre os protocolos ao longo do tempo. Em conclusão, a aplicação de LBI imediatamente após a cirurgia e após 24 e 48 horas (Protocolo A) apresenta melhor resultado para controle da dor. Ambos os protocolos foram similares para dor, edema e trismo. Portanto, por razões de praticidade, uma aplicação única de laser imediatamente após a cirurgia pode estar indicada para o manejo do desconforto pós-operatório em cirurgias de terceiros molares inferiores.

Abstract The gametogenesis and reproduction of S. elegans from the São Francisco River at Três Marias, Minas Gerais, were analyzed in this study. Steindachrina elegans is a species abundant in the São Francisco River basin and an important fish in the food chain. The size at first gonadal maturation (indicated by the total length of the shortest spermatid male and spawned female) was 10.5 cm and 15.0 cm, respectively. Reproduction occurred more frequently from September to April. This period had high water temperature values. A high frequency of females was observed at the mature and spawned stages and height gonadosomatic index (GSI). Meanwhile, in males, the reproductive peak was from November to February. The long spawning period and the histological characteristics of the spawned ovaries that contained oocytes at different stages of development along with post-ovulatory and atretic oocytes indicates that the spawning of S. elegans is of the partial type.

ABSTRACT Purpose: To describe the anatomical aspects of the cervical rootlets and to quantify the number of rootlets that compose C1 to T1. Methods: Twenty male rats were used in this study. The dorsal rootlets from C1 to T1 were analyzed. To study the ventral rootlets, the posterior root avulsion was performed using a microhook, allowing exposure of the ventral roots through manipulation of the denticulate ligament and arachnoid mater. The parameters analyzed were the number of ventral and dorsal rootlets by side and level. Results: The formation of the respective spinal nerve was observed in the spinal roots the union of the ventral and dorsal roots. In four animals the C1 spinal root had no dorsal and/or ventral contribution. There is no normal pattern of numerical normality of the dorsal and ventral rootlets. The average number of fascicles per root was 4.08, with a slight superiority on the left side. There was a slight superiority of the dorsal rootlets compared to the ventral rootlets. Conclusions: This investigation was the first to study cervical rootlets in rats. In 20% of the sample studied, the dorsal root of C1 was absent mainly on the left side. There is a nonlinear numerical increase from C1 to T1 in the rootlets. There is a numerical predominance of cervical fascicles on the left side, confronting several studies related to the functional predominance of right laterality, requiring new studies that correlate these variables.

ABSTRACT Background: The school community was heavily impacted by the Covid-19 pandemic, especially with the long time of school closures. This study aimed to analyze the seroprevalence of SARS-CoV-2 antibodies and possible factors associated with seropositivity for COVID-19 in teachers and other school staff, and to estimate the fraction of asymptomatic individuals by sex and age group. Methods: We conducted a serological survey of SARS-CoV-2 infections. An analytical cross-sectional study was conducted in Fortaleza, Brazil. Teachers and other staff members from pre-schools to universities of higher education to were investigated. Results: A total of 1,901 professionals participated in the study, of which 1,021 were staff and 880 were teachers. The seroprevalence of SARS-CoV-2 was 8.0% (152/1901). In the seropositive group, 48.3% were asymptomatic. There was a predominance of women (68.4%); and, 47.1% of the participants were between 31 and 45 years old. There was an increase in prevalence with increasing age. An inverse relationship was found for education level: more professionals with less education tested positive for COVID-19. The presence of an infected person living in the same household was significantly associated with positive results for COVID-19 among the professionals. Conclusions: This is the first study to report the seroprevalence of IgG against SARS-CoV-2 in Brazilian educational staff after the first wave of the disease. In this study, the seroprevalence was much lower than that in the general population. During school reopening, a small fraction of school workers showed serologically detectable signs of SARS-CoV-2 exposure.

ABSTRACT Purpose: To study the anatomorphometry of the plexus brachialis (PB) of rats under a high-definition video system. Methods: Ten male Wistar rats discarded from other research that did not interfere in the morphology of the animal, respecting the principle of reduction, were used. All animals were submitted to the same protocol. Initially, the cervical region was shaved. The animals were placed in a dorsal position. A single elbow-to-elbow incision was performed and dissection started at the deltopectoral sulcus. The procedures were performed under a video system. To measure the structures, the Image J software was used. Results: All the PB evaluated originated from the C5-T1 spinal nerves. C5 and C6 converged to form the truncus superior, the root of C7 originated the truncus medius, and the confluence of C8 and T1 originated the truncus inferior. It was found the union of C7, C8, and T1 to form truncus inferomedialis instead of separate medial and inferior truncus. C8 (1.31 mm) was the thickest root, the truncus inferior (1.80 mm) and the nerve radialis (1.02 mm), were the thickest. Conclusions: The anatomy of the PB is comparable to humans, admitting variations. The videomagnification system is useful to perform microsurgical dissection.

ABSTRACT Purpose: To describe the technique of sublay correction of incisional hernia in Wistar rats under videomagnification system. Methods: Five male rats of the species Rattus norvegicus, of the Wistar lineage, with body weight between 250–350 g and 60 days old were used. Incisional hernia was inducted in all animals. After that, the incisional hernia was immediately corrected by the sublay method. Results: There were no cases of recurrence of the incisional hernia after placement of the polypropylene mesh using the sublay technique. No postoperative complications were observed. Conclusions: The technique is suitable for execution in Wistar rats.

Resumo Este artigo analisa o itinerário terapêutico de pessoas transgênero em uma cidade do interior da Bahia. Os participantes foram selecionados pelo critério do método da “bola de neve” e utilizou-se entrevista semiestruturada para produção dos dados. Na análise dos itinerários terapêuticos, emergiram três categorias temáticas: 1) Lugares de busca para o cuidado em saúde: traçadores de iniquidades no SUS; 2) Abordagem profissional: reforça os estigmas e cinde a relação terapêutica; e 3) Demandas específicas por cuidado: percalços ao longo do itinerário terapêutico. Os resultados mostraram que o acesso ao serviço formal esteve permeado por barreiras simbólicas, técnicas e/ou organizacionais que, muitas vezes, transferiam para cada um/uma dos/as entrevistados/as a responsabilidade pela busca de outros percursos formais ou recomposição do cuidado por trajetórias nem sempre seguras. A busca pelo setor privado foi preponderante e, paralelamente, houve a desvalorização do SUS. O estigma institucional resultou em abandono de tratamento, retardo na busca por cuidado ou desistência de procura aos serviços. Por fim, a dificuldade de acesso no SUS produzia iniquidades e conduzia as pessoas transgênero, sobretudo as mais vulneráveis, a exposição e experimentação de procedimentos, muitas vezes, inadequados.

Abstract This article examines the therapeutic itineraries of transgender people in a city in the Bahia countryside. Participants were selected using the “snowball” method using semi-structured interviews to produce the data. In the analysis of therapeutic itineraries three thematic categories emerged: 1) Locus of seeking health care: tracers of inequities in SUS; 2) Professional approach: reinforcing stigmas and interrupting the therapeutic relationship; and 3) Specific demands for care: mishaps along the therapeutic itinerary. Results showed that access to formal services was permeated by symbolic, technical and/or organizational barriers. Those barriers frequently transferred the responsibility for the search of alternative formal paths or the restoration of care upon the interviewees, by using trajectories oftentimes unsafe. The search for the private sector was predominant and, in parallel, there was a depreciation of SUS. The institutional stigma resulted in treatment abandonment, delay in looking for care or giving up seeking services. Finally, the difficulties in accessing the SUS produced inequities leading transgender people, especially the most vulnerable, to be exposed and to experiment with often-inadequate procedures.

ABSTRACT New management practices applied to coffee crops may influence the soil’s capacity to tolerate vertical stresses. This paper aimed to evaluate the influence of two coffee crop management systems on the soil load-bearing capacity and critical soil water content to agricultural machinery traffic. This study was performed in the experimental area of the Federal Institute of the Southeast of Minas Gerais - Rio Pomba college, in Rio Pomba city, Minas Gerais, Brazil. Dystrophic Red-Yellow Oxisol (Latossolo Vermelho-Amarelo distrófico) (LVA7) with clayed texture predominating in the experimental unit. Undisturbed soil samples were collected from layers of 0.00-0.03, 0.12-0.15 and 0.27-0.30 m, randomly, in the center of the interrows of coffee plants (Coffea arabica L.) in monoculture plots under traditional management (in full sun) and in the plots of coffee plants intercropped with gliricidia (Gliricidia sepium) (shaded) to estimate pre-consolidation pressures, through uniaxial compression tests and adjustment of soil load-bearing capacity models. The average and maximum normal stresses applied to the soil and the vertical stress distribution of three agricultural tractors used in mechanized farming operations were estimated, and the critical soil water content to the traffic of these tractors was determined for both treatments, aiding in the decision-making process regarding additional compaction risks in the area. Cultivation of gliricidia in consortium with coffee did not influence the soil load-bearing capacity. The soil layer of 0.12-0.15 m was the most vulnerable to vertical stresses in both treatments. Agricultural tractors Agrale 4100, MF 265 and MF 275 presented values of vertical stresses of 335.76, 200.24 and 245.55 kPa, respectively, and the soil water content for the traffic of agricultural machines without plastic deformation was higher in the coffee plants in full sun for all studied depths.
