Polycystic ovary syndrome (PCOS) affects 5-20% of the reproductive age women globally. PCOS is diagnosed by the presence of hyperandrogenism, oligo-anovulation, and polycystic morphology of at least one ovary. Insulin resistance (IR), hyperinsulinemia and associated metabolic abnormalities including metabolic syndrome play a significant role in the development of PCOS. The chances of developing MS in PCOS women was shown to increase by almost 14-fold in patients with increasing body mass index. Even in the absence of overt obesity, a preferential deposition of intra-abdominal fat is noted in PCOS women and this intra-abdominal fat leads to impaired insulin action and functional IR and hyperandrogenism...

Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant. Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was originally considered an incidental hepatic hemangioma prior to being identified as a giant adrenal adenoma. Case description: The patient was a 54 year old obese female with a recent diagnosis of diabetes type II and dyslipidemia with recent ultrasound imaging suggestive of a hepatic hemangioma...

Systemic changes during diabetes such as high glucose, dyslipidemia, hormonal changes and low grade inflammation, are believed to induce structural and functional changes in the cardiomyocyte associated with the development of diabetic cardiomyopathy. One of the hallmarks of the diabetic heart is increased oxidative stress. NADPH-oxidases (NOXs) are important ROS-producing enzymes in the cardiomyocyte mediating both adaptive and maladaptive changes in the heart. NOXs have been suggested as a therapeutic target for several diabetic complications, but their role in diabetic cardiomyopathy is far from elucidated...

Obesity, defined as excessive accumulation of fat in adipose tissue, is a metabolic disorder resulting from behavioral, environmental and heritable causes. Such malfunction increases the risk of developing hypertension, diabetes, cardiovascular disease, respiratory problems, osteoarthritis and cancer. Meanwhile, the negative impact of obesity on male reproduction is gradually being recognized. According to clinical investigations and animal experiments, obesity is correlated with reductions in sperm concentration and motility, increases in sperm DNA damage and changes in reproductive hormonal levels...

Insulin is a key metabolic hormone that controls energy homeostasis in the body, including playing a specific role in regulating reproductive functions. Conditions associated with hyperinsulinemia can lower developmental rates in bovine in vitro embryo production and are linked to decreased fertility in humans, as in cases of obesity or type 2 diabetes. Embryo quality is important for fertility outcome and it can be assessed by choosing scoring standards for various characteristics, such as developmental stage, quality grade, cell number, mitochondrial pattern or actin cytoskeleton structure...

INTRODUCTION: . In traditional medicine, Citrullus colocynthis is used to treat diabetes, hyperlipidemia, cardiovascular diseases, inflammation, and oxidative stress, all of which can appear when a diet rich in vegetable fats, such as palm oil, is continuously consumed. Such high-fat diets are chronic stressors of the hypothalamic-pituitary-adrenal axis. The objective of our study was to analyze and evaluate the effects of colocynth total alkaloids and glycosides on metabolic, hormonal, and structural disorders of the adrenal medulla in Wistar rats fed a high-fat diet...

Type 1 diabetes mellitus (T1DM) is characterized by the loss of insulin secreting cells due to a directed autoimmune process, which is linked to oxidative stress and inflammation. Exercise training is known to induce several benefits by reducing inflammation and improving antioxidant defenses. In this context, exercise training may be considered as an efficient and relatively inexpensive non-pharmacological tool for diabetes treatment, added to the usual insulin administration. Unfortunately, most people with T1DM do not reach the recommended levels of physical activity due to concerns with hypoglycemic episodes...

OBJECTIVE: The aim of this trial was to determine the efficacy of a resistant dextrin on immune-mediated inflammation and hypothalamic-pituitary-adrenal axis in women with type 2 diabetes mellitus (T2DM). METHODS: Females (n = 55) with T2DM were randomly allocated into intervention group (n = 30) and control group (n = 25), in which they received 10 g/d of Nutriose(®)06 (a resistant dextrin) or maltodextrin for 8 weeks, respectively. Fasting blood samples were taken to measure immune system related parameters like white blood cell count, CD4, CD8, interferon-γ (IFNγ), interleukins (IL12, IL4, IL10), cortisol, tryptophan (TRP), ACTH (Adrenocorticotropic hormone), Kynurenine (KYN) and plasma lipopolysaccharide (LPS) at the beginning and end of trial...

BACKGROUND: Currently, there is an epidemic expansion of the obesity rates worldwide. The increasing number of obese individuals associated with the aging of population leads to increasing number of individuals with type 2 diabetes mellitus (T2DM) at the same rate. The traditional factors that link obesity to T2DM are related to genetics, hypercaloric diet, sedentary lifestyle, and stress. Individuals from lower socioeconomic status (SES) have restricted autonomy and opportunities that could lead to more stress and consequently increase in stress hormones, such as cortisol, catecholamines, glucagon, and growth hormone, which might ultimately change fat deposition, increasing visceral fat and increasing the risk of T2DM mellitus development...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting young women. Even though the definition of PCOS has changed over the years, all diagnostic criteria include two or more of the following: oligomenorrhea/oligoovulation/anovulation, androgen excess and polycystic ovaries (PCO). Traditional method of assessing the ovarian morphology has been transvaginal pelvic ultrasound. Recent studies support that serum anti-Mullerian hormone (AMH) levels correlate with the number of ovarian follicles and cysts...

Adiponectin (APN), also known as apM1, Acrp30, GBP28 and adipoQ, is a circulating hormone that is predominantly produced by adipose tissue. Many pharmacological studies have demonstrated that this protein possesses potent anti-diabetic, anti-atherogenic and anti-inflammatory properties. Although several studies have demonstrated the antioxidative activity of this protein, the regulatory mechanisms have not yet been defined in skeletal muscles. The aim of the present study was to examine the cytoprotective effects of APN against damage induced by oxidative stress in mouse-derived C2C12 myoblasts...

IL-6 is a pleiotropic cytokine with complex roles in inflammation and metabolic disease. The role of IL-6 as a pro- or anti-inflammatory cytokine is still unclear. Within the pancreatic islet, IL-6 stimulates secretion of the prosurvival incretin hormone glucagon-like peptide 1 (GLP-1) by α cells and acts directly on β cells to stimulate insulin secretion in vitro Uncovering physiologic mechanisms promoting β-cell survival under conditions of inflammation and stress can identify important pathways for diabetes prevention and treatment...

Smart materials are those materials that are responsive to chemical (organic molecules, chemical agents or specific agents), biochemical (protein, enzymes, growth factors, substrates or ligands), physical (electric field, magnetic field, temperature, pH, ionic strength or radiation) or mechanical (pressure or mechanical stress) signals. These responsive materials interact with the stimuli by changing their properties or conformational structures in a predictable manner. Recently, smart polymers have been utilized in various biomedical applications...

Preserving energy homeostasis in the presence of stressors such as proinflammatory cytokines and nutrient overload is crucial to maintaining normal cellular function. Six-transmembrane epithelial antigen of the prostate 4 (STEAP4), a metalloreductase involved in iron and copper homeostasis, is thought to play a potentially important role in the cellular response to inflammatory stress. Genome-wide association studies have linked various mutations in STEAP4 with the development of metabolic disorders such as obesity, metabolic syndrome, and type 2 diabetes...

Chronic unpredicted mild stress (CUMS)-induced depression could alter the pharmacokinetics of many drugs in rats, however, the underlying mechanism is not clear. In this work we studied the pharmacokinetics of repaglinide, and explored the role of glucocorticoid and adrenergic signaling pathway in regulating drug metabolizing enzymes (DMEs) in GK rats and BRL 3A cells. The plasma cortisol and epinephrine levels were increased, meanwhile the pharmacokinetics of repaglinide were altered significantly in depression model rats...

Previous studies have demonstrated that TWA, a Chinese herbal medicine, could significantly improve the symptoms of patients with diabetic gastrointestinal dysfunction. However, the specific mechanism of regulating intestinal peristalsis has not been found. This study aimed to discover TWA's therapeutic mechanism for regulating intestinal motility. The intestinal propulsion rate of diabetic rats was significantly increased after treatment with TWA for 8 weeks. Aiming at the mechanical structure, biomechanical testing indicated that TWA can significantly decrease the no-load intestinal wall thickness, cross-sectional area, and angular spread in a zero-stress state...

Fibroblast growth factor 21 (FGF21) is a hormone-like member of FGF family which controls metabolic multiorgan crosstalk enhancing energy expenditure through glucose and lipid metabolism. In addition, FGF21 acts as a stress hormone induced by endoplasmic reticulum stress and dysfunctions of mitochondria and autophagy in several tissues. FGF21 also controls stress responses and metabolism by modulating the functions of somatotropic axis and hypothalamic-pituitary-adrenal (HPA) pathway. FGF21 is a potent longevity factor coordinating interactions between energy metabolism and stress responses...

Non-alcoholic fatty liver disease (NAFLD) comprises a spectrum of metabolic states ranging from simple steatosis to inflammation with associated fibrosis to cirrhosis. Though accumulation of hepatic fat is not associated with a significant increase in mortality rates, hepatic inflammation is, as this augments the risk of terminal liver disease, i.e., cirrhosis, hepatic decompensation (liver failure) and/or hepatocellular carcinoma. Disease progression is usually slow, over a decade or more and, for the most part, remains asymptomatic...
