Ghrelin is an orexigenic peptide secreted mainly by the stomach in adult rats. Ghrelin concentrations increase with fasting and decrease after food intake. Ghrelin is also present in the placenta and in the fetal stomach, but the role of fetal ghrelin remains unclear. In this study, we compared changes in plasma ghrelin, insulin, and glucose concentrations and in ghrelin gene expression in stom...

Objetivo: Ampliar o conhecimento acerca das patologias, especialmente na diferenciação diagnóstica de Fetus-in-Fetus (FIF) e teratoma. A partir do estudo da presente revisão bibliográfica, será possível identificar aspectos fisiopatológicos distintos dessas doenças, além diagnóstico diferencial.Métodos: Realizaram-se análises bases dados nacionais estrangeiras no período 2009 a 2023, relatos ca...

background: silymarin is a flavonolignan that has been the subject of research to evaluate the beneficial properties for decades. silymarin has been known for its potent cytoprotective, hepatoprotective and antioxidant activities. the goal of the present study was to gain a deeper understanding of possible molecular mechanisms of apoptosis of the injuries induced by silymarin on balb/c mice fet...

background: several studies have assessed the correlation of fetal choroid plexus cyst (cpc) and the risk of congenital anomalies, but few ones have discussed isolated cpc (with no other abnormal sonographic finding). objective: the aim of this study was to determine the outcome of isolated fetal choroid plexus cyst and to specify its clinical significance. materials and methods: this cross sec...

Endothelial nitric oxide (NO) synthase (eNOS) produces NO, which contributes to vascular reactivity in the fetal lung. Pulmonary vasoreactivity develops during late gestation in the ovine fetal lung, during the period of rapid capillary and alveolar growth. Although eNOS expression peaks near birth in the fetal rat, lung capillary and distal air space development occur much later than in the fe...

Thyroxine (T4) 5'-monodeiodinating activity in rat pituitary was studied, using paper chromatography. Rat anterior pituitary homogenates were incubated with 125I-T4, dithiothreitol and unlabeled L-T4 at 37 degrees C. The incubation mixture was extracted by ethanol and the extracts were subjected to descending paper chromatography. The conversion ratio of T4 to 3, 5, 3'L-triodothyronine (T3) was...

Campylobacter fetus currently comprises three recognized subspecies, which display distinct host association. Campylobacter fetus subsp. fetus and C fetus subsp. venerealis are both associated with endothermic mammals, primarily ruminants, whereas C fetus subsp. testudinum is primarily associated with ectothermic reptiles. Both C. fetus subsp. testudinum and C. fetus subsp. fetus have been asso...
