The role of probiotics on microvascular complications of type-2 diabetes: Nephropathy and retinopathy.

Diabetes is a multifactorial disorder that involves several molecular mechanisms and is still one of the key global health challenges with increasing prevalence and incidence. Gut microbiome dysbiosis could activate and recognize receptors that trigger the inflammation response and modulation of insulin sensitivity. In addition, the intricate role of gut microbiota dysbiosis in the onset and development of T2D (Type 2 diabetes mellitus) and associated microvascular complications was identified.

Docosahexaenoic Acid Reduced Vascular Endothelial Cell Injury in Diabetic Rats Via the Modulation of Autophagy.

Purpose: Among varied ω-3 polyunsaturated fatty acid types, the therapeutic properties of docosahexaenoic acid (DHA) have been indicated under diabetic conditions in different cell lineages. Here, we investigated the anti-diabetic properties of DHA in rats with type 2 diabetes mellitus (D2M) focusing on autophagy-controlling factors.

Methods: D2M was induced in male Wistar rats using a single dose of streptozocin (STZ) and a high-fat diet for 8 weeks.

Mesenchymal stem cell-derived exosomes improve neurogenesis and cognitive function of mice with methamphetamine addiction: A novel treatment approach.

Background: Methamphetamine (METH) is a psychostimulant substance with highly addictive and neurotoxic effects, but no ideal treatment option exists to improve METH-induced neurocognitive deficits. Recently, mesenchymal stem cells (MSCs)-derived exosomes have raised many hopes for treating neurodegenerative sequela of brain disorders. This study aimed to determine the therapeutic potential of MSCs-derived exosomes on cognitive function and neurogenesis of METH-addicted rodents.

Exosomes as a therapeutic tool to promote neurorestoration and cognitive function in neurological conditions: Achieve two ends with a single effort.

Exosomes possess a significant role in intercellular communications. In the nervous system, various neural cells release exosomes that not only own a role in intercellular communications but also eliminate the waste of cells, maintain the myelin sheath, facilitate neurogenesis, and specifically assist in normal cognitive function. In neurological conditions including Parkinson's disease (PD), Alzheimer's disease (AD), traumatic brain injury (TBI), and stroke, exosomal cargo like miRNAs take part in the sequela of conditions and serve as a diagnostic tool of neurological disorders, too.

Bone Marrow-Derived C-Kit Cells Improved Inflammatory IL-33/ST-2/ILC2 Axis in the Lung Tissue of Type 2 Diabetic Rats.

Inflammation is an essential factor in pulmonary complications of diabetes. Bone marrow (BM)-derived C-kit cells have immunomodulatory properties and their transplantation is suggested as a promising strategy for ameliorating diabetes complications. This study evaluated the effect of BM-derived C-kit cells on the inflammation signaling pathway in lung tissue of type 2 diabetic male rats.

Voluntary exercise improves pulmonary inflammation through NF-κB and Nrf2 in type 2 diabetic male rats.

Objectives: This study aimed to evaluate the effects of voluntary exercise as an anti-inflammatory intervention on the pulmonary levels of inflammatory cytokines in type 2 diabetic male rats.

Materials And Methods: Twenty-eight male Wistar rats were divided into four groups (n=7), including control (Col), diabetic (Dia), voluntary exercise (Exe), and diabetic with voluntary exercise (Dia+Exe). Diabetes was induced by a high-fat diet (4 weeks) and intraperitoneal injection of streptozotocin (35 mg/kg), and animals did training on the running wheel for 10 weeks as voluntary exercise.

Chronic Kombucha Beverage Consumption Attenuates Inflammatory Markers and Histopathology of Brain Tissue in Transnet Global Brain Ischemia in Rats.

There is evidence that kombucha beverage (KB), a traditional fermented beverage, has a preventive effect on experimental brain ischemia. According to our previous studies, pre-treatment of KB attenuates brain edema and improves motor skills and oxidative stress in a rat model of global brain ischemia. This study was designed to evaluate the effects of the pre-treatment of KB, as a novel agent, on pro-inflammatory parameters and brain histopathology changes following global brain ischemia.

The effects of voluntary exercise on histological and stereological changes of sciatic nerve, nitric oxide levels, and peripheral neuropathy caused by high-fat diet-induced type 2 diabetes in male rats.

This research was conducted to investigate the possible beneficial impacts of voluntary exercise on sciatic tissue, nitric oxide levels, stereological changes, and peripheral neuropathy caused by "high-fat-diet (HFD)"-induced "type 2 diabetes mellitus (T2DM)" in male rats. Rats were put into four experimental groups at random: "healthy control (C), voluntary exercise (VE), diabetic (D), and diabetic rats treated by voluntary exercise (VED)"; each group contain eight animals. Animals in VE and VED groups performed "voluntary exercise (VE)" for ten weeks.

Bone marrow-derived c-kit positive stem cell administration protects against diabetes-induced nephropathy in a rat model by reversing PI3K/AKT/GSK-3β pathway and inhibiting cell apoptosis.

Stem cell-based therapy has been proposed as a novel therapeutic strategy for diabetic nephropathy. This study was designed to evaluate the effect of systemic administration of rat bone marrow-derived c-kit positive (c-kit) cells on diabetic nephropathy in male rats, focusing on PI3K/AKT/GSK-3β pathway and apoptosis as a possible therapeutic mechanism. Twenty-eight animals were randomly classified into four groups: Control group (C), diabetic group (D), diabetic group, intravenously received 50 μl phosphate-buffered saline (PBS) containing 3 × 10 c-kit cells (D + ckit); and diabetic group, intravenously received 50 μl PBS containing 3 × 10 c-Kit positive cells (D + ckit).

Association of pro-inflammatory cytokines, inflammatory proteins with atherosclerosis index in obese male subjects.

Objectives: Investigation the association of pro-inflammatory markers interleukin (IL)-1β and IL- 10 expression, serum levels of C-reactive protein (CRP), cyclooxygenase-2 (COX2), High-density lipoprotein (HDL), Apolipoprotein A1 (ApoA1), and ATP Binding Cassette Subfamily A Member 1 (ABCA1) inflammatory proteins with atherosclerosis index (homocysteine) in normal-weight and obese male subjects.

Methods: 59 males including 30 obese (Body mass index (BMI) of ≥30 kg/m) and 29 normal-weight (BMI of 18.5-24.
