The effect of vortioxetine on penicillin-induced epileptiform activity in rats

Arq. neuropsiquiatr; 77 (6), 2019
ABSTRACT Vortioxetine is a multimodal antidepressant agent that modulates 5-HT receptors and inhibits the serotonin transporter. It is indicated especially in cases of major depressive disorder related to cognitive dysfunction. There are many studies investigating the effects of antidepressants on the se...

Different sample preparation methods for glomerular morphological evaluation: to coat or not to coat?

Int. j. morphol; 37 (2), 2019
The renal glomerulus is coated by fenestrated endothelial cells and externally covered by specialized epithelial cells, known as podocytes. Scanning electron microscopy becomes an important and effective tool for its studies. Normally, samples destined for scanning microscopy are covered with a thin meta...

Pericyte loss and detachment in experimental cisplatin-induced neuropathy

Int. j. morphol; 37 (2), 2019
Cisplatin is an antineoplastic agent with neuropathy as one of its major side effect. However, effective treatment is lacking. Increasing evidence suggests that cisplatin might damage nerve capillaries leading to impaired functions of blood-nerve barrier (BNB) and neuropathy. This study was aimed to exam...

Hypothyroid offspring replacement with euthyroid wet nurses during lactation improves thyroid programming without modifying metabolic programming

ABSTRACT Objective Determine the milk quality effect during lactation on the metabolic and thyroid programming of hypothyroid offspring. Materials and methods Ten-week-old female Wistar rats were divided into two groups: euthyroid and thyroidectomy-caused hypothyroidism. The rats were matted and, one...

An early stage in T4-induced hyperthyroidism is related to systemic oxidative stress but does not influence the pentose cycle in erythrocytes and systemic inflammatory status

ABSTRACT Objective Hyperthyroidism causes many injuries in its target organs and the consequences are reflected systemically. As systemic alterations in hyperthyroidism at earlier stages have received partial attention, this study aimed to investigate systemic redox and inflammatory status at an early ...

Reparación Ósea en Alvéolos de Ratas Ovariectomizadas con Biosilicato Cristalizado. Análisis Histomorfométrico

RESUMEN: Evaluar el proceso de reparación alveolar en ratas sometidas a cirugía de simulacro u ovariectomizadas tras el relleno alveolar con coágulo o con biosilicato cristalino. Sesenta ratas Wistar fueron divididas en cuatro grupos (n=15) de acuerdo con el tratamiento: Grupo 1- ratas sometidas a cir...

Análise histológica do estômago da prole de ratas Wistar submetidas ao consumo crônico de álcool durante a prenhez

O consumo de bebidas alcoólicas na gravidez consiste em um importante problema de saúde pública, visto que, pode causar prejuízos na organogênese de diversos órgãos, incluindo o estômago, entretanto, poucos estudos avaliam o efeito da exposição pré-natal ao álcool nesse órgão. O objetivo d...

Papel protector del ácido fólico en un biomodelo de intoxicación alcohólica prenatal en ratas Wistar

Introducción: el etanol es un agente teratógeno cuyo consumo excesivo representa un importante problema de salud a nivel mundial. Objetivo: demostrar el papel protector del ácido fólico sobre el Sistema Nervioso Central y las dimensiones craneofaciales, en un biomodelo de intoxicación alcohólica p...

Effects of Chronic Exposure to Mercury on Angiotensin-Converting Enzyme Activity and Oxidative Stress in Normotensive and Hypertensive Rats

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Mercury's deleterious effects are associated with increased cardiovascular risk. Objective: To determine whether chronic exposure to inorganic mercury increases the activity of angiotensin-converting enzyme and its relationship with oxidative stress in several organs and tissues. ...

Antioxidant effect of the pequi oil (Caryocar brasiliense) on the hepatic tissue of rats trained by exhaustive swimming exercises

Braz. j. biol; 79 (2), 2019
Abstract Increased oxygen consumption and activation of specific metabolic pathways during or after physical exercise lead to the formation of reactive oxygen and nitrogen species. An investigation was made into the effects of pequi oil supplementation in protecting liver cells against injury resulting ...
