Potential of piperine for neuroprotection in sepsis-associated encephalopathy.

Aims: Sepsis-associated encephalopathy (SAE) is a common complication that increases mortality and leads to long-term cognitive impairment in sepsis survivors. However, no specific or effective therapy has been identified for this complication. Piperine is an alkaloid known for its anti-inflammatory, antioxidant, and neuroprotective properties, which are important characteristics for treatment of SAE.

High-fat diet increases mortality and intensifies immunometabolic changes in septic mice.

Immunometabolic changes in the liver and white adipose tissue caused by high-fat (HF) diet intake may worse metabolic adaptation and protection against pathogens in sepsis. We investigate the effect of chronic HF diet (15 weeks) on mortality and immunometabolic responses in female mice after sepsis induced by cecum ligation and perforation (CLP). At week 14, animals were divided into four groups: sham C diet, sepsis C diet (C-Sp), sham HF diet (HF-Sh) and sepsis HF diet (HF-Sp).

EPA/DHA and linseed oil have different effects on liver and adipose tissue in rats fed with a high-fat diet.

The incidence of cardiovascular diseases and metabolic disorders has increased worldwide. Clinical and experimental research has shown that the consumption of ω-3 FAs can be beneficial to metabolism in several ways, as they can act on metabolic pathways. Our objective was to evaluate the effect of treatment with linseed oil, a vegetable oil rich in alpha-linolenic acid, and EPA and DHA in different proportions (3:1 EPA:DHA, and 1:3 EPA:DHA), on the metabolic disorders induced by a high-fat diet (20 % lipids) in rats for 2 weeks, after 18 weeks of consumption of a high-fat diet.

Temporal effect of fructose supplementation at different concentrations on hepatic metabolism of Wistar rats.

Introduction: in the last few years important changes have occurred in nutritional patterns. There has been an increase in the consumption of simple carbohydrates such as fructose, which has been associated with numerous metabolic disorders, including hepatic steatosis. Materials and methods: we sought to evaluate the impact of fructose consumption, as diluted in water at different concentrations, for two time periods, on the metabolic parameters of Wistar rats using ANOVA.

Açaí ( Martius) Promotes Jejunal Tissue Regeneration by Enhancing Antioxidant Response in 5-Fluorouracil-Induced Mucositis.

Intestinal mucositis (IM) caused by antineoplastic chemotherapy is characterized by an important inflammatory process, which may compromise ongoing treatment. Our study aimed to investigate the effect of Açaí (Euterpe oleracea Martius) on the antioxidant response in BALB/c mice pretreated with Açaí pulp (200 g/kg) for 14 day. A group of animals receiving a single intraperitoneal injection of 5-FU (200 mg/kg) were euthanized on day three (D3) or seven (D7) after administration, the distal jejunum was isolated for the analyses of histology, superoxide dismutase (SOD) and catalase (CAT) enzyme activities, and concentration of total sulfhydryl groups (GSH).
