Protective effect of long-chain polyunsaturated fatty acids on hepatorenal syndrome in rats.

Background: Hepatorenal syndrome (HRS) is the most prevalent form of acute kidney injury in cirrhotic patients. It is characterized by reduced renal blood flow and represents the most severe complication in cirrhotic patients with advanced disease. Previous research has indicated that antioxidants can delay the onset of a hyperdynamic circulatory state in cirrhosis and improve renal function in HRS patients.

Zinc Supplementation Partially Decreases the Harmful Effects of a Cafeteria Diet in Rats but Does Not Prevent Intestinal Dysbiosis.

Zinc (Zn) plays an important role in metabolic homeostasis and may modulate neurological impairment related to obesity. The present study aimed to evaluate the effect of Zn supplementation on the intestinal microbiota, fatty acid profile, and neurofunctional parameters in obese male Wistar rats. Rats were fed a cafeteria diet (CAF), composed of ultra-processed and highly caloric and palatable foods, for 20 weeks to induce obesity.

Neuroinflammatory responses following zinc or branched-chain amino acids supplementation in obese rats.

The excessive production of pro-inflammatory mediators, characteristic of obesity, leads to neuroinflammation. Zinc (Zn) and the branched-chain amino acids (BCAA) are supplements known for their immunomodulatory properties. Our goal was to evaluate if Zn or BCAA supplementation can affect long-term recognition memory and neuroinflammatory parameters of obese rats after a high-fat diet (HFD).

Effect of Melatonin on the Reduction of Hepatic Steatosis and Intestinal Leptin Expression in Zebrafish Exposed to Fructose.

Melatonin is a hormone related to circadian rhythms and has potential clinical applications. Our objectives were to verify the effect of melatonin on the liver of zebrafish exposed to fructose and evaluate the expression of appetite-related genes (leptin, ghrelin, and melanocortin receptor 4 [MC4R]). Animals were divided into three groups: control (CG,  = 25), fructose (FG,  = 25), and fructose+melatonin (FMG,  = 25).

Zinc Supplementation Decreases Obesity-Related Neuroinflammation and Improves Metabolic Function and Memory in Rats.

Objective: The purpose of this study was to evaluate the effects of zinc (Zn) supplementation on metabolic and neuroinflammatory parameters in cafeteria diet (CAF)-induced obesity in Wistar rats.

Methods: Animals were divided into four groups: control diet (CT); CT+Zn; CAF; CAF+Zn. The diet was administered for 20 weeks; Zn treatment (10 mg/kg/d) started at week 16 and it was conducted until the end of the diet protocol.

Food Selection of Cafeteria Diet Affects Memory Dysfunction Related to Obesity.

Cafeteria diet (CAF) mimics human Western diet and has been used in animal models to study obesity. The purpose of this study is to demonstrate that our CAF model induces metabolic disorder related to obesity and affects recognition memory in Wistar rats. We also compared the intake of two different soft drinks, as part of the CAF, on recognition memory.

Altered expression of COX-2 and TNF-α in patients with hepatocellular carcinoma.

Background And Aim: hepatocellular carcinoma is a type of cancer related with inflammation, as 90% of cases develop in a chronic inflammation condition. Excess inflammation can affect tissue homeostasis. Cytokines and inflammatory mediators are immunological components that can influence the functioning of cells and tissues.

Maternal feeding associated to post-weaning diet affects metabolic and behavioral parameters in female offspring.

Genetic and environmental factors related to maternal diet may predispose offspring to serious diseases. However, consequences of a maternal diet intervention during gestation and lactation, and its association with caloric restriction after weaning on the progeny are not completely known. In this context, the goal of the present study was to investigate how different maternal diets, control (CONT), hypercaloric (HD) or restrictive (RD) diets during gestation and lactation, may affect the metabolism and behavior of the offspring that was also submitted to RD.

Zinc supplementation reduces diet-induced obesity and improves insulin sensitivity in rats.

Rates of obesity have been growing at alarming rates, compromising the health of the world population. Thus, the search for interventions that address the metabolic repercussions of obesity are necessary. Here we evaluated the metabolic and antioxidant effects of zinc and branched-chain amino acids (BCAA) supplementation on obese rats.

Omega-3 fatty acids revert high-fat diet-induced neuroinflammation but not recognition memory impairment in rats.

Neuroinflammation is a consequence of overeating and may predispose to the development of cognitive decline and neurological disorders. This study aimed to evaluate the impact of omega-3 supplementation on memory and neuroinflammatory markers in rats fed a high-fat diet. Male Wistar rats were divided into four groups: standard diet (SD); standard diet + omega-3 (SD + O); high fat diet (HFD); and high fat diet + omega-3 (HFD + O).

Low maternal care is associated with increased oxidative stress in the brain of lactating rats.

Maternal care is crucial for offspring development and licking/grooming patterns can be induced by sensorial, neuroendocrine, and metabolic variations in the CNS. Important brain functions, such as learning and memory, can be influenced by oxidative stress, which can also modulate pathophysiological processes (e.g.

The effect of celecoxib on the development of diethylnitrosamine-induced liver tumors in rats.
