Squamous cell carcinoma in cattle, sheep and horse. study of 50 cases in south ...
Basso, Andréa Cristina; Gracia, Joaquim Mansana; Esper, Cesar RobertoThe objective of this study is to use different in vitro culture systems of preantral follicles from Nelore breed bovine fetuses in the last gestation quarter. The evaluation of treatments considered the time of growth of isolated follicles. Preantral follicles were mechanically isolated and submitted to the individual culture, for 9 days, in media no supplemented or supplemented with fetal calf serum (FCS), bo...
Morfogenesis of Testis From Embryos and Fetuses of Nelore Breed Cows (Bos tauru...
Jacomini, José Octavio; Esper, Cesar Roberto; Diniz, Elmo Gomes; Vieira, Rogerio Chaves; Beletti, Marcelo EmilioThe aim of this study was to accompany the process of testicular development from the non-differentiable phase to its complete formation. Embryos and fetuses of Nelore breed cows (Bos Taurus indicus) were obtained in slaughterhouses near the Uberlandia city, Minas Gerais. The gonads and the embryos were fixed in Bouin's fixative and afterwards processed for conventional optical microscopy. The gonadal was obser...

Basso, Andréa Cristina; Esper, Cesar RobertoFolículos pré-antrais de 41 vacas da raça Nelore foram quantitativa e ultraestruturalmente descritos neste estudo. Uma média de 35.539,20 folículos pré-antrais foram isolados mecanicamente ("Tissue Chopper") por animal. Os folículos foram processados para microscopia eletrônica de transmissão. Os folículos primordiais apresentaram um oócito rodeado por uma camada de células granulosas (CGs) achatadas, com algum...

Seneda, Marcelo Marcondes; Esper, Cesar Roberto; Garcia, Joaquim Mansano; Andrade, Evelyn RabeloSince the first work about embryo collection, a great amount of research and development has founded on enhancing genetic contribution of cows. The aim of this publication is to give an account of the current knowledge, new findings and techniques on recovery of oocytes from cattle donors.; Desde o primeiro relato de colheita de embriões, um grande número de trabalhos tem apresentado os esforços para melhorar a...
Evaluation of oocyte maturation conditions and bull effect on the in vitro bovi...
Coelho, Lia de Alencar; Esper, Cesar Roberto; Garcia, Joaquim Mansano; Vantini, Roberta; Silva Filho, Izaltino Rocha; Almeida Jr., Ivo LuisThe conditions of in vitro maturation of bovine oocytes (Exp. I) and bull effect (Exp. II) on cleavage (CR) and the in vitro morulae and blastocysts (MO/BL) rates were evaluated. Imatured oocytes were matured in vitro under different conditions: B-199 medium with 5% estrous cow serum (ECS), 5% fetal calf serum (FCS) and granulosa cells (T1/Exp. I) or B-199 medium with 10% FCS, 14 IU/ml PMSG and 7 IU/ml hCG (T2/...
