Morphological features and vascularization study of caprine cyclic corpus luteum
Miranda-Moura,Maria Tereza M.; Fonseca,Vanessa Uemura da; Silva,Naisandra Bezerra da; Freitas,Maria de Lourdes; Almeida,Osiel Benedito deCorpus luteum is a temporary endocrine gland that regulates either the estrous cycle and pregnancy. It presents extreme dependency on the adequate blood supply. This work aims to evaluate goat corpus luteum (CL) vascular density (VD) over the estrous cycle. For that purpose, 20 females were submitted to estrus synchronization/ovulation treatment using a medroxyprogesterone intra-vaginal sponge as well as intram...
Morfologia do tubo digestório da tartaruga verde (Chelonia mydas)
Magalhães,Marcela S.; Freitas,Maria de Lourdes; Silva,Naisandra B. da; Moura,Carlos Eduardo B. dePara avaliar a morfologia do tubo digestório da tartaruga verde (Chelonia mydas) 10 animais, 9 juvenis e 1 adulto, foram analisados. A retirada dos órgãos digestórios procedeu-se após abertura do plastrão. A descrição e a medida do comprimento de cada órgão [esôfago, estômago, intestino delgado (ID) e intestino grosso (IG)] foram realizadas com o tubo digestório aberto. Os resultados mostraram que tanto nos ani...
Spectrophotometric determination of uranium using 2-(2- Thiazolylazo)-p-Cresol ...
Teixeira,Leonardo Sena Gomes; Costa,Antonio Celso Spínola; Ferreira,Sérgio Luís Costa; Freitas,Maria de Lourdes; Carvalho,Marcelo Souza deA sensitive and selective spectrophotometric method is proposed for the rapid determination of uranium using 2-(2- Thiazolylazo)-p-Cresol (TAC). The reaction between TAC and uranium (VI) is instantaneous at pH 6.5 and the absorbance remains stable for over 3 h. N-cetyl-N,N,N-trimethylamonium bromide (CTAB) and triton X-100 are used for increasing the sensitivity and solubility of the system respectively. The me...
