RESUMO
Annually millions of animals are killed as a result of human-wildlife impacts. Each year the NGO Associação Mata Ciliar (NGOMC), in Southeastern Brazil, receives and rehabilitates thousands of animals. We evaluated how natural and anthropogenic characteristics affect the risk of different types of human-wildlife impacts for mammals that arrive at the NGOMC; and explore the relationship between both the animal's size and the type of human-wildlife impact event, survival rates and the likelihood that these animals can be fully rehabilitated. To test our hypotheses regarding the drivers and consequences of the total number of human-wildlife impact events, traffic collisions, electrocutions, and requested removals, we used records of the mammals that arrived at the NGOMC between 2012 and 2018, and obtained data on environmental attributes and anthropogenic factors at the municipality level, as well as species weights. The total number of human-wildlife impact events and of requested removals were both positively correlated with deforestation rate and urban area. The number of traffic collisions was positively related to the number of fires. Municipalities with larger urban areas were more likely to have at least one electrocuted mammal. Temporally, the number of fires two months before was positively correlated with the number of human-wildlife impact events. Traffic collisions and electrocutions more frequently resulted in the death of the animal, than did other events. Animals that died were heavier on average than those that remained in captivity or were successfully released back into the wild. We conclude that human-wildlife impact event rates should decline with lower rates of deforestation, less anthropogenic fires and the adoption of other specific measures to avoid both traffic collisions with fauna and electrocutions.

Bats can be monoestrous or polyestrous, and seasonal or non-seasonal in their reproductive patterns. The strategy adopted by each species or population depends on the regional climate. The objective this study was to analyze reproductive data of Sturnira lilium from long-term sampling carried out in several sites in Rio de Janeiro states, southeastern Brazil. We carried out sampling in 42 sites (with altitudes ranging from sea level to 1300 m a.s.l.) from May 1989 to December 2011. In total, we obtained 2602 captures of S. lilium: 1242 captures of adult females, 1225 captures of adult males, and 136 captures of subadults. The sex ratio was 0.99 males: 1 female. The reproductive season varied from eight to twelve months a year, and it was not related to the total accumulated rainfall. Sturnira lilium have continuously polyestrous reproduction with postpartum estrus and pregnant females can be observed in all months except July. In the present study, the highest proportions of pregnant females were observed in the months with the highest rainfall.(AU)
Os morcegos podem ser monoestrais ou poliestrais e sazonais ou assazonais em relação aos padrões reprodutivos. A estratégia adotada por cada espécie ou população depende do clima regional. O objetivo deste estudo foi analisar os dados reprodutivos de Sturnira lilium em amostragem de longo prazo realizado em diversos locais do Estado do Rio de Janeiro, sudeste do Brasil. De maio de 1989 a dezembro de 2011, realizamos amostragens em 42 locais (com altitudes que variam de 0 a 1300 m de altitude). No total, obteve 2602 capturas de S. lilium: 1242 fêmeas adultas, 1225 machos adultos e 136 subadultos. A proporção sexual foi 0.99 machos: 1 fêmea. A temporada reprodutiva variou de oito a doze meses por ano e não foi relacionada com o total de precipitação acumulada. Sturnira lilium apresenta reprodução contínua poliéstrica com estro pós-parto e fêmeas grávidas podem ser observadas em todos os meses, exceto o mês de julho. No presente estudo, as maiores proporções de fêmeas grávidas ocorreram nos meses com maior precipitação.(AU)

Sampling allows assessing the impact of human activities on mammal communities. It is also possible to assess the accuracy of different sampling methods, especially when the sampling effort is similar. The present study aimed at comparing two mammalian surveys carried out over a three-year interval, in terms of sampling effort, capture success, abundance of domestic dogs, impact of human activities, and relative biomass using camera traps, in the Serra do Japi Biological Reserve and surroundings, located in Jundiaí, state of São Paulo, southeastern Brazil. The total richness recorded was 13 species, one domestic and 12 wild mammals. Sampling effort in both surveys was similar, but capture success and number of captures differed. The abundance of wild mammals and dogs did also differ between surveys. There was a highly significant correlation between abundance of wild mammals and capture effort for the survey performed in 2006/2007, but not for the survey performed in 2009/2010. The difference between samples may be related to human disturbance, since the number of domestic mammals photographed was higher in the second survey, three years after the first survey. Despite being a reserve, the area is still under pressure from urbanization, biological invasion, environmental degradation, and hunting, which may reduce the abundance of wild mammals.

Uma das formas de avaliar o impacto das atividades humanas nas comunidades de mamíferos e ter maior conhecimento e acurácia sobre o método utilizado é realizar amostragens, proporcionando a comparação do método, principalmente quando o esforço amostral é semelhante. O presente estudo visou a comparar dois levantamentos de mamíferos realizados na mesma área com três anos de intervalo, quanto aos seguintes aspectos: esforço amostral, sucesso de captura, abundância de cães domésticos, presença de atividades humanas e biomassa relativa das espécies. A riqueza total obtida nos dois períodos de amostragem foi de 13 espécies, sendo 12 espécies selvagens e uma de animal doméstico. O esforço de amostragem para as duas pesquisas foi semelhante, porém o sucesso de captura foi diferente, quando comparados entre si. A abundância de mamíferos selvagens e cães também mostrou diferenças entre os dois períodos. A correlação entre a abundância de mamíferos selvagens e o esforço de captura provou ser altamente significativa para a amostragem realizada em 2006/2007, mas não foi significativa para a realizada em 2009/2010. A diferença entre as amostras pode estar ligada à perturbação humana nesse ambiente, já que o número de animais domésticos fotografados foi maior após três anos de amostragem. Apesar de ser uma área de conservação, também está sujeita a pressões, como especulação imobiliária, invasões, destruição e caça, o que pode estar diminuindo a abundância das espécies selvagens listadas neste trabalho.(AU)

PIP: A critical evaluation of hormonal contraceptives is presented. The pills have been used for more than 100 million women all over the world. During the 25 years of their commercialization, there has been an improvement in their composition, today being considered almost perfect. The side effects can be summarized in 3 groups: endocrine-sexual such as vomiting, headaches, menstrual irregularity; systemic such as thromboembolism, sodium retention, hypertension; and general such as irritability and sexual dysfunction. The pills have some protective effects in the endometrium against cancer, and also against pelvic inflammations. They also can be used to treat uterine bleeding and endometriosis.^ieng

Quarenta e cinco pacientes com processos inflamatorios anexiais agudos e cronicos foram tratadas, durante oito a 12 dias, com 400 mg de feprazona (duas capsulas com 200 mg cada), administrados em dose unica diaria, apos o jantar. Os resultados foram considerados bons em 41 (91%) e regulares em quatro casos, nao se registrando insucessos terapeuticos. A tolerabilidade foi satisfatoria, tendo apenas quatro pacientes apresentado efeitos colaterais (gastralgia e/ou prurido) de baixa intensidade, que nao obrigaram a interrupcao do tratamento. Os controles laboratoriais mantiveram-se imodificados. Nesta serie de observacoes, a posologia de 400 mg, em administracao unica diaria, revelou ser altamente eficaz e bem tolerada
