Superimposing a high-fat diet on schistosoma mansoni infection affects renin-angiotensin system components in the mouse kidney

Abstract INTRODUCTION: The levels of the full-length form of the (pro)renin receptor (PRR), a component of the renin-angiotensin system (RAS), may be reduced in the membranes of kidneys in renal diseases. This study aimed to investigate the RAS components in the kidneys of mice submitted to a combinatio...

Glycogen synthase kinase-3 beta inhibitors protectagainst the acute lung injuries resulting from acute necrotizing pancreatitis

Acta cir. bras; 34 (6), 2019
Abstract Purpose The research is intended for clarification of the efficacy as well as the underlying mechanism of GSK-3β inhibitors on the advancement of acute lung injuries in acute necrotizing pancreatitis (ANP) in rats. Methods Seventy-two rats were randomly divided into 6 groups: (1)ANP-veh...

Avaliação do mecanismo epigenético por metilação do DNA e da expressão de GLUT4 em tecido muscular esquelético de ratos adultos, proles de ratas com doença periodontal

Atualmente, está bem estabelecido que o ambiente fetal está ligado à saúde materna, e estímulos ou agressões anormais durante a vida intra-uterina podem resultar em mudanças na fisiologia e metabolismo da prole, aumentando o risco de doenças na vida adulta. Tal fenômeno é conhecido como program...

Baicalin ameliorates chronic mild stress-induced depression-like behaviors in mice and attenuates inflammatory cytokines and oxidative stress

Braz. j. med. biol. res; 52 (7), 2019
The natural flavonoid glycoside baicalin (BA) produces a variety of pharmaceutical effects, particularly for psychiatric/neurological disorders. This study evaluated the behavioral and neuroprotective effects of BA in mice subjected to chronic unpredictable mild stress, a model of depression. BA (25 and ...

Effect of risperidone on proliferation and apoptosis of MC3T3-E1 cells

Braz. j. med. biol. res; 52 (3), 2019
This aim of this study was to assess the molecular mechanism of osteoporosis in schizophrenia patients with risperidone use. Here, we investigated the effects of risperidone on cellular proliferation and apoptosis of a preosteoblast cell line, MC3T3-E1. Cell viability and apoptotic rate of MC3T3-E1 were ...

Anti-inflammatory and antinociceptive effects of phonophoresis in animal models: a randomized experimental study

Braz. j. med. biol. res; 52 (2), 2019
The aim of this study was to evaluate the therapeutic effects of ultrasound (US)-mediated phonophoresis alone or in association with diclofenac diethylammonium (DCF) administered topically in animal models of inflammation. A pre-clinical, prospective, and randomized experimental study of quantitative and...

Elevated serum Activin A in chronic obstructive pulmonary disease with skeletal muscle wasting

Clinics; 74 (), 2019
OBJECTIVE: Muscle wasting contributes to the reduced quality of life and increased mortality in chronic obstructive pulmonary disease (COPD). Muscle atrophy in mice with cachexia was caused by Activin A binding to ActRIIB. The role of circulating Activin A leading to muscle atrophy in COPD remains elusiv...

Necroptosis occurs in osteoblasts during tumor necrosis factor-α stimulation and caspase-8 inhibition

Braz. j. med. biol. res; 52 (1), 2019
Necroptosis is a regulated cell death mechanism. However, it is unknown whether necroptosis is involved in the death of tumor necrosis factor-α (TNF-α)-treated osteoblasts. Therefore, we conducted the study with TNF-α, Nec-1 (a specific inhibitor of necroptosis), and Z-IETD-FMK (a specific...

Ginsenoside Rd inhibits IL-1β-induced inflammation and degradation of intervertebral disc chondrocytes by increasing IL1RAP ubiquitination

Braz. j. med. biol. res; 52 (9), 2019
Many compounds of ginsenosides show anti-inflammatory properties. However, their anti-inflammatory effects in intervertebral chondrocytes in the presence of inflammatory factors have never been shown. Increased levels of pro-inflammatory cytokines are generally associated with the degradation and death o...

Inflammatory markers in the saliva of cerebral palsy individuals with gingivitis after periodontal treatment

Abstract The aim of this study was to evaluate the effect of periodontal treatment on the salivary cytokine levels and clinical parameters of individuals with cerebral palsy (CP) with gingivitis. A non-randomized, clinical trial was conducted in individuals diagnosed with spastic CP. Thirty-eight individ...
