Assessment of remnant liver function and volume after selective ligation of portal vein and hepatic artery in a rat model

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepa...

Mating with seminal vesicle-excised male can affect the uterus phospholipid fatty-acids composition during implantation in an experimental mouse model

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Purpose No comprehensive information is available about uterus fatty acid (FA) change during implantation period and possible effects of the seminal vesicle secretion on it. Materials and Methods In this study, we evaluated FA composition of uterus phospholipids during the implantation perio...

Environmental enrichment reduces brain excitability in adult rats overnourished during lactation

Arq. neuropsiquiatr; 77 (8), 2019
ABSTRACT Objective: This study aimed to analyze whether exposure to environmental enrichment (EE) during the juvenile phase of life interferes with the electrical activity of the adult rat brain. In addition, the present research also investigated whether this putative effect on brain electrical activit...

Pituitary gland volumes in patients with obsessive-compulsive disorder before and after cognitive-behavioral therapy

Objective: The beneficial effects of psychopharmacological and cognitive behavioral therapy (CBT) on the brain are not well understood. In a previous study, we found smaller pituitary volumes in patients with obsessive-compulsive disorder (OCD). The purpose of this study was to examine the effect of CBT ...

Protection mediated by chemokine CXCL10 in BALB/c mice infected by Leishmania infantum

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Visceral leishmaniasis (VL) caused by Leishmania infantum is characterised by the loss of the ability of the host to generate an effective immune response. Chemokines have a direct involvement in the pathogenesis of leishmaniasis, causing a rapid change in the expression of these molecules du...

Quantitative analysis of the renal aging in rats. Stereological study

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To evaluate the renal function and the renal histological alterations through the stereology and morphometrics in rats submitted to the natural process of aging. METHODS: Seventy two Wistar rats, divided in six groups. Each group was sacrificed in a different age: 3, 6, 9, 12, 18 and...

Efeitos da dietilpropiona, energia da dieta e sexo sobre o ganho de peso corporal, peso dos órgäos e deposiçäo de tecidos em ratos
Effects of diethylpropion, diet energy and sex on the corporal weight gain, organs weight and tissues deposition in rats

O objetivo deste trabalho foi avaliar a dietilpropiona (DEP), um derivadoo fenetilamínico utilizado como anorexígeno, e dietas de diferentes densidades calóricas, utilizando ratos de ambos os sexos. O experimento contou com 72 ratos Wistar distribuídos por sexo, bloqueados por peso inicial e alocados...
