Quirópteros da Estação Ecológica da Serra das Araras, Mato Grosso, Brasil, com o primeiro registro de Artibeus gnomus e A. anderseni para o cerrado

We present the results of the first bat inventory at the 'Serra das Araras' Ecological Station, MT, in the northwestern portion of the Cerrado domain. We captured bats using the traditional ground-level mist netting and, occasionally, high nets placed 3 m above the ground, and hand nets for hoosting bats. We recorded 23 species distributed in six families (Emballonuridae, Noctilionidae, Mormoopidae, Phyllostomidae, Molossidae, and Vespertilionidae), including Artibeus gnomus and A. anderseni, which had never been recorded in the Cerrado domain. © 2004 Instituto de Ciências Biológicas - UFMG.

Compreendendo o significado da gestação para grávidas diabéticas.

This qualitative study intends to understand the meaning of pregnancy for diabetic women. Semi-structured interviews were carried out and data were analyzed by means of the Collective Subject Discourse, identifying the following central ideas: happiness about a desired pregnancy, preoccupation with pregnancy and renouncement, my pregnancy was planned, I had other plans, I feel what pregnant women feel, I had many problems during pregnancy, a child was everything that he wanted, he didn't feel the same emotions as a woman, I am controlling, doing everything the doctor says, I am trying to follow a diet, but it is hard. These central ideas demonstrate that, among the diabetic pregnant women, planning and wanting the pregnancy and counting on the support of the family and/or companion were also essential for the treatment to be faced naturally and for the pregnancy to be experienced in a pleasant way.

Primeiro registro documentado de Alectrurus tricolor para o Pantanal, Brasil

The Cock-tailed Tyrant (Alectrurus tricolor, Vielliot 1816) is reported here for the first time in the Brazilian Pantanal. The species was seen twice (August and September 2005) in the northern portion of Fazenda Rio Negro, in the region of Nhecolândia. Sexual displays were observed, suggesting that reproduction is occuring in this area.

Utilização do primeiro ciclo ovulatório da estação reprodutiva para produção de embriões em éguas sob condições tropicais

The efficacy of the first ovulation of the breeding season was determined through the response of first pre-ovulatory follicle of the breeding season to hCG, embryo recovery rate, viability of recovered embryos, serum concentrations of progesterone, and response of first CL to PGF 2α. Thirteenth mares that were in vernal transition were accompanied until the first pre-ovulatory follicle was detected. At this moment, the ovulation was induced with 2,500 IU hCG (IV) and the mares were inseminated every other day until ovulation. Seven days after the ovulation, embryo recovery was performed and the progesterone concentration was determined. After detection of the first pre-ovulatory follicle of breeding season with ≥ 25mm, it took 14.92 ± 10.80 days for the follicle to reach the preovulatory size and 18.00 ± 11.08 days to ovulation. After administration of hCG, 11/13 mares ovulated in 48 hours. These follicles growth 2.19 ± 0.86 mm/day on average. Nine of 13 mares (69.2%) produced embryos and all were considered viable after morfological evaluation and fluorescence exams. The CL appeared competent producing 7.39 ± 2.11 ng/ml P 4 on average, and responding to PGF 2α. According to these results the first ovulatory cycle of the year can be utilized to produce viable embryos.

Morfologia e morfometria dos tipos de fibras do músculo reto abdominal de cadelas (canis familiaris) durante a gestação

The present paper deals with the evaluation of morphological and morphometric alterations of slow-twist (I) and fast-twitch (II) fibers of rectus abdominis muscle of adult female dog during pregestational phase, at 30 and 60 days of pregnancy and at 30 days after the parturition. At the every phases, using the open biopsy technique, muscle samples were collected. The samples were plunged. Histological sections were cut in a microtome. For general morphology, some sections were stained with HE. Subsequent sections were reacted for myofibrillar ATPase (m-ATPase), after alkaline (pH 10.4) and acid (pH 4.4) pre-incubations, in order to identificate type I and II fibers. In the pre-gestational phase, muscle tissue revealed to be composed by fibers with different diameters, presenting polygonal outlines and one or more periphery nuclei. At 30 days of pregnancy, muscle fiber characteristics were similar. At 60 days, in addition to the existence of normal fibers, polymorphic and small diameter fibers were frequent. At 30 days after the parturation, the morphology of muscle fiber were similar to that observed in the pre-gestational phase. In the four phases, type II fiber diameters were lager than type I. The diameters of both fiber types showed a significant reduction in the 30 days phase and a significative increasing at 60 days. The expansion of the abdominal wall during the pregnancy represents a chronic stimulus, induced changes in the morphology and in the fiber type diameters.

Quantificação do interferon-tau durante o reconhecimento materno da gestação em fêmeas bovinas Bos taurus indicus

During the critical period of the maternal recognition, which occurs between days 15 and 19 of pregnancy, the conceptus must competently synthesize molecules capable of blocking the synthesis of prostaglandin F2α (PGF2α) and luteolysis. In cattle, the major macromolecule involved in suck blockage is the protein interferontau (IFN-τ). During the critical period, failures in the recognition of pregnancy determine embryonic mortality on up to 40% of inseminated cows. Data about IFN-τ in Bos taurus indicus are still scarce. Objective of this study was to quantitatively evaluate the presence of IFN-τ during the critical period for maternal recognition of pregnancy in uterine flushings obtained in vivo by Foley catheter (Days 14, 16 and 18 post estrus) or post-mortem (Day 18 post estrus). Multiparous, cyclic or pregnant zebu cows (Bos taurus indicus) on days 14, 16 and 18 post estrus were used for in vivo or post mortem uterine flushing collection. In both cases, a Ringer solution was used to wash the uterus of cows. Uterine flushings were concentrated by ultrafiltration and lyophilized. Proteins were separated by one-dimensional electrophoresis (SDS-PAGE) in a 15% polyacrilamide gel. Interferontau quantification in uterine flushings was performed by western blotting and densitometry. Non-specific protein bands were observed in both in vivo and post mortem uterine flushings. Interferon-tau was detected only in uterine flushings obtained from pregnant cows post-mortem (P<0.05). Optical density of protein bands was not affected by the day of the critical period, state (cyclic or pregnant) or interaction day x state. There was no effect of the conceptus weight or progesterone concentration on the day of uterine flushing collection in the optical density of the IFN-τ protein band. It was concluded that the detection and quantification of IFN-τ in the uterine environment of zebu cows, in these experimental?conditions, is only possible in uterine flushings obtained post-mortem.

Primeiro registro de Harpia harpyja para o bioma Pantanal, com dados sobre atividade reprodutiva

The first reliable encounter of the Harpy Eagle Harpia harpyja in the Pantanal floodplains is reported, with information on its breeding activity in the region, as well as some prey. A nest was found in August 2009, located in Barão de Melgaço County, northern portion of the Pantanal, with a 60-90-day-old eaglet. After a windy storm on August 30, the nest fell, causing the death of the nestling. In March 2010 another nest was located about 2.6 km distant from the first. We emphasize the importance of this record, and the need for a monitoring program to evaluate the true status of the Harpy Eagle in the northern portion of the Pantanal and nearby areas.

Primeiro relato de atividade patogênica de Hirsutella thompsonii (Fischer) sobre o ácaro-da-erinose-da-lichia Aceria litchii (Keifer)

The litchi erineum mite, Aceria litchii (Keifer) is found in all producing regions attacking leaves and flowers of litchi plants. The mite attack young leaves and causes the erinea on leaf surface, which later become brown galls with velvety appearance. Severe attacks can cause leaf drop and destruction of branches end directly production affecting. In 2009 year it was registered a heavy infestation of the pest on litchi plants (Litchi chinensis Sonn.) in the municipality of Casa Branca, São Paulo, Brazil (2127'O; 4702'S; 679 m altitude). In June, many galls caused by mite infestation showed a mycelium of white coloration and many eriophyid dead. The fungus was identified as Hirsutella thompsonii (Fischer). The results suggest that galls may facilitate the fungus development and its permanence on the plants. Thus, the possibility of mite biological control with H. thompsonii should be investigated.

Primeiro registro de Molossus coibensis (Chiroptera: Molossidae) na Amazônia Brasileira

This study reports on the occurrence of Molossus coibensis J. A. Allen, 1904, in the Brazilian Amazon and the second record of this species from Brazil. It also presents a comparative analysis with other two small-bodied Molossus species that occur in Brazil: M. molossus (Pallas, 1766) and M. aztecus Saussure, 1860. The report is based on 8 females captured in urban areas of the city of Bragança, in the northern Brazilian state of Pará. Morphometric data and the qualitative comparison of morphological features permitted the identification of the specimens as M. coibensis, hitherto known only in Tapirapoan, in the southwestern state of Mato Grosso, west-central Brazil. © SAREM, 2013.

Perda e luto: Vivências de mulheres que interromperam a gestação por malformação fetal letal

The scope of this study was to investigate the grieving experiences of women who terminated pregnancies under judicial authorization, due to life-incompatible fetal malformation. Ten women attended in the Fetal Medicine Department of Botucatu Clinical Hospital participated in the study. Data collection was conducted by means of semi-structured interviews forty days after termination. The interviews were recorded and transcribed in full, with the data analyzed from the thematic content analysis perspective. The results revealed that the mothers sought explanations and meanings for the loss, with religious responses and self-blame being very frequent. The reports were marked by feelings of sadness, longing and sensations of emptiness due to the loss of the child, revealing the need of the mothers to dwell on the issue. The mothers were and continued to be linked to their children; the termination of the pregnancy, although being a choice to minimize the pain of an inevitable loss, did not spare the women from experiences of great suffering. The study includes input for the discussion and planning of health approaches and care for women who terminate their pregnancy due to lethal fetal malformation, by means of judicial authorization.
