BACKGROUND: Chronic high-fat diet (HFD) consumption caused not only obese-insulin resistance, but also cognitive decline and microglial hyperactivity. Modified gut microbiota by prebiotics and probiotics improved obese-insulin resistance. However, the effects of prebiotics, probiotics, and synbiotics on cognition and microglial activity in an obese-insulin resistant condition have not yet been investigated. We aimed to evaluate the effect of prebiotic (Xyloolidosaccharide), probiotic (Lactobacillus paracasei HII01), or synbiotics in male obese-insulin resistant rats induced by a HFD...

Dietary changes are a major lifestyle factor that can influence the progression of chronic diseases such as diabetes. Recently, flavanols, a subgroup of plant-derived phytochemicals called flavonoids, have gained increasing attention, due to studies showing an inverse correlation between dietary intake of flavanols and incidence of diabetes. Flavanoids in the cocoa plant may ameliorate insulin resistance by improving endothelial function, altering glucose metabolism, and reducing oxidative stress. Oxidative stress has been proposed as the main culprit for insulin resistance...

The effects of melatonin (MLT), which exerts cardioprotective effects against myocardial apoptosis, in long‑term diabetic cardiomyopathy are not currently well defined. The present study aimed to investigate how MLT protects the heart through modulating myocardial apoptosis in rats with type 2 diabetes mellitus (DM). In total, 36 rats were randomly divided into three groups, including control (n=12), DM (n=12) and DM + MLT (n=12) groups. The results demonstrated that, in DM rats, a significant increase was observed in the serum fasting blood glucose and lipid levels, in addition to insulin resistance and cardiac dysfunction, which were attenuated in DM rats treated with MLT...

AIMS/HYPOTHESIS: While the underlying mechanisms in the development of insulin resistance remain inconclusive, metabolic dysfunction in both white adipose tissue (WAT) and skeletal muscle have been implicated in the process. Therefore, we investigated the independent and combined effects of α-linolenic acid (ALA) supplementation and exercise training on whole-body glucose homeostasis and mitochondrial bioenergetics within the WAT and skeletal muscle of obese Zucker rats. METHODS: We randomly assigned obese Zucker rats to receive a control diet alone or supplemented with ALA and to remain sedentary or undergo exercise training for 4 weeks (CON-Sed, ALA-Sed, CON-Ex and ALA-Ex groups)...

Multiple pathways contribute to nonalcoholic fatty liver disease (NAFLD) in response to high fat diets (HFD). A homolog of mammalian JNK-interacting protein 3 (JIP3), also known as JSAP-1, activates different components in various signaling pathways to modulate cellular processes. The purpose of this study was to examine the role of JIP3 in obesity-related pathologies pathway. Wild-type (WT) C57BL/6 and JIP3-knockout (JIP3(-/-)) mice were randomized to chow or HFD. HFD-fed WT mice increased hepatic JIP3 expression...

Delay in the initiation of breastfeeding is one of the problems of cesarean section. Its causes are insulin resistance, pain, anxiety, stress, thirst, hunger, and so on. Preoperative oral carbohydrate (OCH) reduces postoperative insulin resistance and improves postoperative recovery. The present study was conducted to evaluate the effect of preoperative oral carbohydrate on breastfeeding after cesarean section. In this double-blind randomized clinical trial, 91 pregnant women who underwent elective cesarean section were randomly assigned to preoperative OCH (Nutricia Preop; n = 45) or control group (water flavored with lemon; n = 46)...
