Plasma Melatonin and Progesterone Profiles of Suffolk and Romney Marsh Ewes Implanted with Melatonin during Anoestrus Season at Lower Latitudes in Southern Hemisphere

Background: The subcutaneous implants of melatonin are stimulatory and mimic the positive effects of short photoperiod on reproduction in small ruminants. This study investigated the daily plasma melatonin profiles in ewes treated with melatonin implants and kept under natural photoperiod in Southeastern Brazil. The plasma progesterone concentrations were also investigated before and after melatonin implantation.Materials, Methods & Results: Romney Marsh (n = 11) and Suffolk (n = 10) ewes, which had been isolated from rams for at least 2 months prior to the beginning of the trial, were randomly allocated in two groups based on melatonin implant treatment (with or without melatonin implant). For plasma melatonin concentration, 43 days after melatonin implantation and 3 days before the ram introduction blood samples were collected every 2 hours during 24 hours. For plasma progesterone concentrations, blood samples were collected every once to twice a week for 2 different periods: prior to melatonin implantation and 46 days after the melatonin implantation and at the same day of the introduction of rams. The hormonal concentrations were determined by the radioimmunoassay method (RIA). The data were analyzed according to MIXED procedure (SAS) as repeated measurements for random animal effects. The effect of melatonin treatment on plasma melatonin 24-h period varied according to the breed. At the dark-phase, there were no plasma melatonin differences (P > 0.05) between implanted and no-implanted (228.02 ± 58.39 vs. 169.59 ± 48.39) Romney Marsh ewes whereas for Suffolk ewes the plasma melatonin levels were higher in implanted (305.61 ± 68.39 pg/mL) than no-implanted (151.26 ± 38.35 pg/mL) ones. At the light-phase, melatonin treatment effects could be evidenced and these differences (P than 1 ng/mL in implanted and no-implanted Suffolk ewes. In implanted Romney Marsh ewes the elevation of progesterone mean values was weak whereas in no-implanted Romney Marsh ewes the progesterone levels were maintained ˂ 1 ng/mL during all the blood sample collection times.Discussion: The melatonin treatment also produced a similar model of daily melatonin levels as reported previously by others, which is characterized by high plasma melatonin concentrations during the light phase of the day. The effect of melatonin implants on plasma melatonin profiles interacted with breed confirming an individual response to melatonin implantation which is proportional to genetic individual variation pattern of melatonin secretion. Before the melatonin implantation all Romney Marsh and Suffolk ewes were judged to be in non-ovulatory period (anoestrus) with plasma progesterone mean values lower than 1 ng/mL. The melatonin treatment helped to induce the ovulatory activity in most of the ewes that were in anestrous at the time of melatonin implantation and the efficacy of this treatment depends on the individual variation in ovulatory response to ram introduction. In Southeastern Brazil., melatonin implant altered the daily plasma melatonin profiles of Suffolk and Romney Marsh ewes by increasing the melatonin levels during the light-phase of the day. Melatonin implant also induced an ovulatory response in Suffolk and Romney Marsh after the introduction of the rams. For no-implanted Suffolk ewes, the male effect is sufficient to provoke an ovulatory response

Características anuais da atividade estral em borregas lanadas e deslanadas mantidas sob condição subtropical

The increased emphasis placed on lamb production in Brazil points to the need for a better knowledge of the annual pattern of reproductive activity in ewe lambs. This study evaluates the annual estrous activity pattern of hair and wool ewe lambs raised in southeast Brazil. Estrous characteristics were recorded for 12 months in ten Santa Inês and 21 Romney Marsh and Suffolk ewe lambs. Santa Inês ewe lambs exhibited a greater length of the normal estrous cycle (14 to 19 days) than Romney Marsh and Suffolk ewe lambs (17.0 ± 0.1 days vs. 16.5 ± 0.2 and 15.9 ± 0.2 days). All the ewe lambs presented a greater number of periods of estrus per animal per month for single estrous cycles (up to 26 days) during autumn and winter. During spring and summer there was a reduction of this number but this decline varied according to the breed. For Santa Inês ewe lambs the reduction was only significant in the summer. For wool ewe lambs the reduction was significant in both seasons but was more accentuated for Romney Marsh. The Romney Marsh ewe lambs had a more restricted breeding season than Suffolk and both presented optimal estrus activity in autumn and winter. Santa Inês ewe lambs had a continuous distribution of estrous cycles along the year, although presenting a reduction in the number of estrous periods in the summer. The ewe lambs of three breeds presented characteristics of sexual immaturity, like irregular estrous cycles and silent ovulations.Em função do maior interesse pela ovinocultura de corte na região Sudeste do Brasil há necessidade de conhecer melhor o padrão anual da atividade reprodutiva das borregas. Esse estudo avaliou esse padrão anual em borregas deslanadas e lanadas criadas nessa região. A atividade cíclica reprodutiva foi avaliada durante 12 meses em dez borregas da raça Santa Inês e 21 borregas das raças Romney Marsh (11) e Suffolk (10). A duração dos ciclos estrais normais (14 a 19 dias) das fêmeas Santa Inês foi maior do que a duração observada nas fêmeas Romney Marsh e Suffolk (17,0 ± 0,1 dias vs. 16,5 ± 0,2 e 15,9 ± 0,2 dias). Todas as borregas apresentaram um elevado número de períodos de estros/animal/mês para ciclos estrais simples (até 26 dias) durante o outono e inverno. Houve redução desse número durante a primavera e o verão, mas esse declínio variou conforme a raça. Para as borregas Santa Inês essa redução só foi significativa no verão enquanto que para as fêmeas das raças lanadas, a redução foi significativa em ambas as estações e mais acentuada nas fêmeas Romney Marsh. As fêmeas dessa raça também apresentaram uma estação reprodutiva mais restrita do que as fêmeas Suffolk havendo uma concentração dos estros durante o outono e inverno para as fêmeas de ambas as raças. As fêmeas Santa Inês apresentaram uma distribuição equilibrada dos estros ao longo do ano embora tenha havido uma redução do número de período de estros durante o verão. As borregas das três raças apresentaram características de imaturidade sexual como ciclos estrais irregulares e ovulações silenciosas

EGRESSOS DE UM PROGRAMA DE RESIDÊNCIA MULTIPROFISSIONAL EM CARDIOPNEUMOLOGIA E INSERÇÃO NO MERCADO DE TRABALHO

A Residência Multiprofissional é uma importante estratégia de Educação Permanente (EPS) no Sistema Único de Saúde (SUS), sendo a primeira oportunidade para muitos recém-graduados de exercer sua profissão e adquirir experiência. O objetivo do presente estudo foi conhecer o perfil de profissionais egressos de um programa de Residência Multiprofissional em Cardiopneumologia no Ceará e sua inserção no mercado de trabalho. No estudo, transversal e quantitativo, coletaram-se dados socioeconômicos, sociodemográficos e sobre histórico no mercado de trabalho, entre junho e outubro de 2022, via formulário eletrônico enviado aos egressos. A grande maioria estava empregada, atuando no SUS como terceirizados, vinculados como celetistas ou cooperados, em áreas de atuação diversas, destacando o potencial de contribuição na saúde, na educação e na gestão pública. Estudos com profissionais egressos de outros programas hospitalares são necessários para melhor elucidar as potencialidades, contribuições e lacunas do processo formativo à inserção dos profissionais no mercado de trabalho

Ações do Grupo de Apoio Pedagógico (GAP) em prol do ensino de graduação da Faculdade de Zootecnia e Engenharia de Alimentos (FZEA)

This report presents the activities performed by GAP-FZEA during the period of 2005 to 2016 and their impact on the occupation of FZEA teachers in relation to teaching/learning process. Before the creation of Course Coordinating Committees (CoCs), the GAP-FZEA helped the FZEA teachers to draw the professional profile of Higher Education students and also helped them to think about their own pedagogical formation. After the CoCs creation, besides the GAP-FZEA was continuing to work in direction to pedagogical formation of the teachers, they mainly focus on helping the CoCs of FZEA in thinking about the construction of PoliticalPedagogical Project (PPP). Later, the GAP-FZEA promoted the I Simpósio de Graduação da FZEA, which give to teachers the opportunity to exchange experiences regarding to pedagogical management and practice. The GAP-FZEA provides favorable conditions to congregate the teachers by stimulating the discussion about teaching/learning process.O presente relato apresenta as ações exercidas pelo GAP-FZEA durante o período de 2005 a 2016 e o seu impacto nas atividades desenvolvidas pelos docentes da FZEA pertinentes ao ensino de graduação. Antes da criação das Comissões Coordenadoras de Curso (CoCs), o GAP-FZEA atuou diretamente na promoção de eventos sobre gestão pedagógica dando subsídios aos docentes para que os mesmos refletissem sobre a necessidade de traçar o perfil profissional do estudante e sobre sua própria formação pedagógica. Após a criação das CoCs, o GAPFZEA, além de continuar trabalhando na formação pedagógica dos docentes da FZEA, atuou indiretamente na gestão pedagógica dando subsídios às CoCs da FZEA para que as mesmas reflitam sobre a construção dos Projetos Políticos Pedagógicos (PPPs). Posteriormente, o GAP-FZEA promoveu o I Simpósio de Graduação da FZEA, que permitiu a troca de experiências vivenciadas pelos docentes da FZEA quanto à gestão e à prática pedagógica. O GAP-FZEA mostrou que pode propiciar espaços para congregar os docentes e estimular o debate sobre as práticas de ensino-aprendizagem na construção desse ambiente de aprimoramento

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Sensitivity of South American tropical forests to an extreme climate anomaly

The tropical forest carbon sink is known to be drought sensitive, but it is unclear which forests are the most vulnerable to extreme events. Forests with hotter and drier baseline conditions may be protected by prior adaptation, or more vulnerable because they operate closer to physiological limits. Here we report that forests in drier South American climates experienced the greatest impacts of the 2015–2016 El Niño, indicating greater vulnerability to extreme temperatures and drought. The long-term, ground-measured tree-by-tree responses of 123 forest plots across tropical South America show that the biomass carbon sink ceased during the event with carbon balance becoming indistinguishable from zero (−0.02 ± 0.37 Mg C ha −1 per year). However, intact tropical South American forests overall were no more sensitive to the extreme 2015–2016 El Niño than to previous less intense events, remaining a key defence against climate change as long as they are protected
