PURPOSE: An imbalance in the production of adipokines and myokines impairs the energy expenditure, increases adipocyte and develops metabolic pathologies. Physical exercise is able to regulate the secretion of myokines and adipokines. The present study considers the metabolic cross talk between skeletal muscle and adipose tissue in high-intensity interval training vs. moderate-intensity continuous training by regulation of PGC-1α. METHODS: A sample of 32 male Wistar rats (8 weeks old with mean weight 250 ± 55 g) were divided into four groups randomly: control of base (CO), control of 8 weeks (CO8w), moderate-intensity continuous training (MICT), and high-intensity interval training (HIIT)...

OBJECTIVE: The goal of this study was to evaluate the importance of nesfatin-1, acylated and des-acylated ghrelin, which are known as energy regulatory hormones, in patients with moderate and severe major depression disorders (MDD). METHODS: Thirty patients with a moderate degree of MDD and, 30 with a severe degree of MDD were used as participants in this study. Thirty subjects without depression were enrolled as a control group. The Hamilton Depression Rating Scale was used to classify the patients with MDD...

Nesfatin is an anti-inflammatory molecule that reduces atherosclerotic cardiovascular risk. By contrast, visfatin has pro-inflammatory properties and is pro-atherogenic. We examined the potential impact of nesfatin and visfatin on atherosclerotic disease in 232 (113 black and 119 white) consecutive rheumatoid arthritis (RA) patients from 2 centers. Independent relationships of nesfatin and visfatin concentrations with metabolic risk factors, endothelial activation, carotid atherosclerosis and altered plaque stability were determined in multivariable regression models...

The aims of this study were to investigate the impacts of acute aerobic exercise on circulating levels of hormones associated with energy metabolism, namely leptin, nesfatin-1 and irisin, in trained and untrained male subjects and to determine whether the timing of the exercise (i.e. morning or night) amplified these impacts. Thirty trained (19.2±0.7 years) and 30 untrained (19.5±0.6 years) male subjects performed two aerobic running exercises (3 days between tests) to 64-76% of the subjects' maximal heart rate for about 30 min...

BACKGROUND: Despite of its significant therapeutic effects on obesity and metabolic diseases, Roux-en-Y gastric bypass (RYGB) has limited clinical application because of considerable impacts on the gastrointestinal structure and postoperative complications. This study aims to develop a simplified surgical approach with less damage and complication but efficient metabolic benefit. METHODS: The effects of Esophagus-Duodenum gastric bypass (EDGB) on body weight, food intake, glucose and lipid metabolism were compared to RYGB in mice...

In order to elucidate the contribution of cycloxygenase (COX) enzymes in the anti-oxidant and anti-inflammatory mechanisms of nesfatin-1, which improves the healing process of chronic gastric ulcers, either acetic acid (80%; ulcer groups; n = 40) or saline (control groups; n = 40) was applied to the serosal surface of male Sprague Dawley rats' stomachs for 1 min. Both the control and ulcer groups were treated daily with either i.p. saline or nesfatin-1 (0.3 μg/kg; for 3 days). Nesfatin-1-treatment was preceded with i...

Nesfatin-1 and ghrelin are two hormones which has opposite effects and play role in food intake. This study was planned on the idea that both metabolic syndrome and psychiatric disorders are associated with nesfatin-1 and ghrelin. In this study, it was aimed to investigate the levels of ghrelin and nesfatin-1 in patients with schizophrenia, by taking confounding factor as the metabolic syndrome (MS). 55 patients with schizophrenia and 33 healthy controls were included in the study.11 out of the 55 patients (%20) has MS...

AIM: To establish a rat model of anxiety-like gastric hypersensitivity (GHS) of functional dyspepsia (FD) induced by novel sequential stress. METHODS: Animal pups were divided into two groups from postnatal day 2: controls and the sequential-stress-treated. The sequential-stress-treated group received maternal separation and acute gastric irritation early in life and restraint stress in adulthood; controls were reared undisturbed with their mothers. Rats in both groups were followed to adulthood (8 wk) at which point the anxiety-like behaviors and visceromotor responses to gastric distention (20-100 mmHg) and gastric emptying were tested...

The gastric X/A-like cell was long thought to be restricted to the production of acyl ghrelin. However, the subsequent years witnessed the discovery of other peptide products derived from this cell, namely desacyl ghrelin, obestatin and nesfatin-1. While the role of obestatin remains highly questionable and is very critically discussed in the literature, besides acyl ghrelin also desacyl ghrelin and nesfatin-1 have been implicated in the regulation of food intake. As observed for several other peptide hormones before, ghrelin and nesfatin-1 are not restricted to one function but rather exert pleiotropic actions including effects on gastrointestinal motility, thermogenesis, lipid and glucose homeostasis, stress mediation, cardiovascular as well as reproductive functions...

AIM: We aimed to evaluate the relationship between Nesfatin-1 levels and slow coronary flow (SCF). METHODS: A total of 60 consecutive patients with SCF and 60 consecutive patients with the normal coronary flow (NCF) were enrolled into the study. Nesfatin-1 level was measured from blood serum samples using enzyme-linked immunosorbent assay test...

Adipokines and other biomarkers were previously identified with roles in energy expenditure, appetite, satiety, and adiposity. Therefore, we investigated whether dietary weight loss-induced changes in adipokines and other biomarkers known to play a role in weight regulation or energy expenditure could predict weight regain in people with overweight and obesity. In this randomized controlled trial 26 males and 30 females (BMI: 28-35 kg/m2 ) followed either a low-calorie diet (LCD; 1250 kcal/day) for 12 weeks or a very-low-calorie diet (VLCD; 500 kcal/day) for 5 weeks followed by a weight stable period of 4 weeks (dietary intervention (DI) period) and a 9-month follow-up period...

BACKGROUND: This study aimed to examine the effects of nesfatin-1 on thoracic aorta vasoreactivity and to investigate the inotropic and chronotropic effects of nesfatin-1 on the spontaneous contractions of the isolated rat atria. METHODS: Isolated right atria and thoracic aorta were used in organ baths. The reactivity of the thoracic aorta was evaluated by potassium chloride (KCl), phenylephrine (Phe), acetylcholine (ACh), and sodium nitroprusside (SNP). The effects of nesfatin-1 on the spontaneous contractions of the rat atria were also examined...

Phoenixin-14 (PNX) is a newly identified peptide co-expressed in the hypothalamus with the anorexic and cardioactive Nesfatin-1. Like Nesfatin-1, PNX is able to cross the blood-brain barrier and this suggests a role in peripheral modulation. Preliminary mass spectrography data indicate that, in addition to the hypothalamus, PNX is present in the mammalian heart. This study aimed to quantify PNX expression in the rat heart, and to evaluate whether the peptide influences the myocardial function under basal condition and in the presence of ischemia/reperfusion (I/R)...

Nesfatin-1, a food-intake inhibiting factor processed from nucleobindin 2 (NUCB2), was originally identified by the Oh-I research group. The initial functional studies on NUCB2/nesfatin-1 were mainly focused on its properties of appetite regulation. As is well known, emotional state has an interactional relationship with food intake, and difficulties in regulating emotion and stress have a great influence on appetite and body weight. Some anorexigenic or orexigenic neurotransmitters also play a role in the adjustment of emotion and stress responses in addition to their actions on the homeostatic regulation of food intake, including neuropeptide Y (NPY), melanocyte stimulating hormone (MSH), corticotropin-releasing factor (CRF), and ghrelin...

Activity-based anorexia (ABA) is an established animal model for the eating disorder anorexia nervosa (AN). The pathophysiology of AN and the involvement of food intake-regulatory peptides is still poorly understood. Nesfatin-1, an anorexigenic peptide also involved in the mediation of stress, anxiety and depression might be a likely candidate involved in the pathogenesis of AN. Therefore, activation of nesfatin-1 immunoreactive (ir) brain nuclei was investigated under conditions of ABA. Female Sprague-Dawley rats were used and divided into four groups (n=6/group): activity-based anorexia (ABA), restricted feeding (RF), activity (AC) and ad libitum fed (AL)...
