Characterization of bovine transcripts preferentially expressed in testis and with a putative role in spermatogenesis
(Theriogenology, 2011-10-01) [Artigo]
Although the number of genes known to be associated with bovine spermatogenesis has increased in the past few years, regulation of this biological process remains poorly understood. Therefore, discovery of new male fertility ...
Efeitos da redução ou substituição do soro fetal bovino por outros compostos na maturação in vitro de oócitos bovinos
(Pesquisa Veterinária Brasileira, 2014-07-01) [Artigo]
The use of fetal calf serum (FCS), although widely employed during in vitro production (IVP) of bovine embryos, has limitations. FCS is an undefined media and may have harmful effects on the quality of embryos. For this ...
Annual profile of fecal androgen and glucocorticoid levels in free-living male American kestrels from southern mid-latitude areas
(General and Comparative Endocrinology, 2010-03-01) [Artigo]
Fecal samples and behavioral data were collected at a fortnightly basis during 11 months period from free-living male American kestrels living in southeast Brazil (22 degrees S latitude). The aim was to investigate the ...
Comparison of methods for the detection of biofilm formation by Staphylococcus aureus isolated from bovine subclinical mastitis
(Brazilian Journal of Microbiology, 2013-01-01) [Artigo]
Biofilm formation is considered to be a selective advantage for Staphylococcus aureus mastitis isolates by facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and ...
Isolation of bovine coronavirus (BCoV) in monolayers of HmLu-1 cells
(Brazilian Journal of Microbiology, 2005-09-01) [Artigo]
A partir de 20 amostras fecais de bezerros, com quadro clínico de diarréia, positivas para BCoV por hemaglutinação/inibição da hemaglutinação (HA/HI), procedeu-se o isolamento viral em monocamadas de células da linhagem ...
Diminished CD4+/CD25+T cell and increased IFN-gamma levels occur in dogs vaccinated with Leishmune (R) in an endemic area for visceral leishmaniasis
(Veterinary Immunology and Immunopathology, 2010-06-15) [Artigo]
The Leishmune (R) vaccine has been used in endemic areas to prevent canine visceral leishmaniasis in Brazil, but cytokine production induced by vaccination has rarely been investigated in dogs. This study aimed to evaluate ...
The Crowned Solitary-eagle Harpyhaliaetus coronatus (Accipitridae) in the cerrado of Estacao Ecologica de Itirapina, southeast Brazil.
(Revista Brasileira de Ornitologia, 2006-12-01) [Artigo]
Imprinted gene expression in in vivo- And in vi/ro-produced bovine embryos and chorio-allantoic membranes
(Genetics and Molecular Research, 2009-06-15) [Artigo]
Cloning by nuclear transfer is often associated with poor results due to abnormal nuclear reprogramming of somatic donor cells and altered gene expression patterns. We investigated the expression patterns of imprinted genes ...
Immunoprophylactic strategies against enterotoxemia caused by Clostridium perfringens type D in goats
(Pesquisa Veterinária Brasileira, 2006-03-01) [Artigo]
Foi avaliada a resposta sorológica de vacina experimental contra a enterotoxemia em quatro grupos de caprinos. O Grupo 1 recebeu colostro de vacas não vacinadas e nenhuma dose de vacina. Os Grupos 2, 3 e 4 receberam colostro ...
B-mode Ultrasound and Doppler Mode for Early-stage Pregnancy Diagnosis in Shi-Tzu Bitches
(Acta Scientiae Veterinariae, 2013-11-12) [Artigo]
Background: The very first sign to confirm pregnancy in bitches is the gestacional sac detection. In this primary moment, it is very small with only few millimeters. The average time for gestational sacs visualization is ...
