Effects of Probiotics on Colitis-Induced Exacerbation of Alzheimer's Disease in Mice.

Alzheimer's disease (AD) is characterized by progressive cognitive decline and is a leading cause of death in the United States. Neuroinflammation has been implicated in the progression of AD, and several recent studies suggest that peripheral immune dysfunction may influence the disease. Continuing evidence indicates that intestinal dysbiosis is an attribute of AD, and inflammatory bowel disease (IBD) has been shown to aggravate cognitive impairment.

Evaluation of Serum miRNA-24, miRNA-29a and miRNA-502-3p Expression in PCOS Subjects: Correlation with Biochemical Parameters Related to PCOS and Insulin Resistance.

MicroRNAs (miRNAs) are small, endogenous, non-coding, single stranded RNAs which play a role in the regulation of gene expression and function. Therefore, the analysis of differentially expressed miRNAs are of great importance in disease diagnosis. This study is focussed on the differential expression of miRNAs in serum of PCOS subjects compared to control and their correlation with metabolic and endocrine parameters.

Supplementation of scopoletin improves insulin sensitivity by attenuating the derangements of insulin signaling through AMPK.

Scopoletin (SPL), a phenolic coumarin, is reported to regulate glucose metabolism. This study is initiated to substantiate the action of SPL on the regulation of insulin signaling in insulin resistant RIN5f cells and high fat, high fructose diet (HFFD)-fed rat model. Adult male Sprague Dawley rats were fed HFFD for 45 days to induce type 2 diabetes and then treated or untreated with SPL for the next 45 days.

Grape seed proanthocyanidins and metformin combination attenuate hepatic endoplasmic reticulum stress in rats subjected to nutrition excess.

Context: Endoplasmic reticulum (ER) stress in the liver is a pathological outcome of nutrient excess and is suggested to be one of the hits for progressive liver injury.

Objective: This study investigated whether grape seed proanthocyanidins (GSP) and metformin (MET) alone or in combination can relieve hepatic ER stress induced in rats subjected to calorie excess.

Material And Methods: Male albino Wistar rats were given high calorie diet (HCD) for 45 days, while GSP (100 mg/kg body weight) and MET (50 mg/kg body weight) were administered either alone or in combination for last 15 days.

Troxerutin abrogates mitochondrial oxidative stress and myocardial apoptosis in mice fed calorie-rich diet.

Mitochondrial oxidative stress plays a major role in the pathogenesis of myocardial apoptosis in metabolic syndrome (MS) patients. In this study, we investigated the effect of troxerutin (TX), an antioxidant on mitochondrial oxidative stress and apoptotic markers in heart of mice fed fat and fructose-rich diet. Adult male Mus musculus mice were fed either control diet or high fat, high fructose diet (HFFD) for 60 days to induce MS.

Apigenin attenuates hippocampal oxidative events, inflammation and pathological alterations in rats fed high fat, fructose diet.

High calorie diet promotes oxidative stress and chronic low grade inflammation that predispose to brain dysfunction and neurodegeneration. Hippocampus region of the brain has been shown to be particularly sensitive to high calorie diet. We hypothesize that apigenin (API), a flavonoid could attenuate hippocampal derangements induced by high fat-high fructose diet (HFFD).

Troxerutin attenuates diet-induced oxidative stress, impairment of mitochondrial biogenesis and respiratory chain complexes in mice heart.

Mitochondrial abnormality is thought to play a key role in cardiac disease originating from the metabolic syndrome (MS). We evaluated the effect of troxerutin (TX), a semi-synthetic derivative of the natural bioflavanoid rutin, on the respiratory chain complex activity, oxidative stress, mitochondrial biogenesis and dynamics in heart of high fat, high fructose diet (HFFD) -induced mouse model of MS. Adult male Mus musculus mice of body weight 25-30 g were fed either control diet or HFFD for 60 days.

High-calorie diet inflates steatogenic effects of valproic acid in mice.

Valproic acid (VPA) is an anti-epileptic drug used in patients with convulsive seizures and psychic disorders. Despite its therapeutic use, VPA administration is associated with several side effects of which hepatosteatosis (lipid deposition in liver >10% of organ weight) is of concern. Recently, the consumption of western-type diet rich in fat and simple sugar has increased, the pathological consequences of which has been linked to the escalating incidence of metabolic disorders.
