The object of the present work was to study the relationship between acute pancreatitis (PA) and hyperlipidic diets. PA was induced by Caerulein (CE) by a single intraperitoneal doses (50 mcg/kg), after feeding the rats during 6 weeks with an hyperlipidic diet (45%). Rats with a normolipidic diet (lipids 5%) were used as control. The increase of serum lipase was similar in both groups treated with CE (control and with hyperlipidic diet). There were increase of interstitial edema, cariorrexis and a specially marked increase in the level of vacuolization of acinar cells with respect to the control group. It was concluded that chronic hyperlipidic diet increases histopathologic lesions in PA induced by CE in rats.

The aim of this study was to evaluate the potential effects of administering mangaba powder on liver function and somatic, oxidative and lipid metabolism parameters in rats fed a high-fat diet. Prepared mangaba powder has important amounts of phenolic compounds, vitamin C, dietary fiber and oligosaccharides. A total of 32 adult Wistar rats were initially randomized into two groups for the biological assay: normal-fat (NF, n = 16) and high-fat (HF, n = 16) diets for 21 days.

Brown adipose tissue (BAT) participates in thermogenesis and energy homeostasis. Studies on factors capable of influencing BAT function, such as a high-fat diet (HFD) or exposure to environmental pollutants, could be useful for finding metabolic targets for maintaining energy homeostasis. We evaluated the effect of chronic exposure to dichlorodiphenyldichloroethylene (DDE), the major metabolite of dichlorodiphenyltrichloroethane (DDT), and/or a HFD on BAT morphology, mitochondrial mass, dynamics, and oxidative stress in rats.

The rates of overweight and obesity around the world have increased in past years. The body's adipose tissue stimulates the antioxidant and oxidation imbalance capacity at the cellular level. This scenario favors an inflammatory low-grade systemic condition starting with insulin resistance, which in turn may involve diabetes mellitus type 2 and cognitive decline afterward.

Genetic factors, diet, lifestyle, and other factors lead to various complications in the body, such as obesity and other chronic diseases. The inflammatory state caused by excessive accumulation of body fat affects the pathways related to the control of glycemic homeostasis, leading to a high demand for insulin, to subsequent failure of stressed β cells, and development of type 2 diabetes mellitus (T2DM). The study of new endocrine signalers, such as bile acids (BAs), becomes necessary as it allows the development of alternatives for T2DM treatment.

Purpose: The present study aimed at evaluating possible synergistic effects between two risk factors for cognitive decline and neurodegenerative disorders, i.e. iron overload and exposure to a hypercaloric/hyperlipidic diet, on cognition, insulin resistance, and hippocampal GLUT1, GLUT3, Insr mRNA expression, and AKT phosporylation.
