Patients with diabetes often have difficult-to-heal wounds. Spinacia oleracea extract comprises anti-inflammatory and anti-oxidative compounds; this research, therefore, studied the impact of Spinacia oleracea extracts on ulcer regeneration. This study was conducted on 72 adult Wistar rats (200 [Formula: see text] 20 g).

Our study was carried out to investigate dietary, biochemical, anthropometric and body composition parameters and physical activity in obese women with normal and low resting energy expenditure.

This study aimed to examine association between variant rs17782313 near melanocortin-4 receptor (MC4R) gene and behavioral and hormonal factors then evaluated interactions between variant MC4R rs17782313 with behavioral and hormonal factors on obesity.
Methods: This cross-sectional study included 403 subjects, overweight and/or obesity, aged 20-50 years from Iran.
Background: Circadian Locomotor Output Cycles Kaput (CLOCK), an essential element of the positive regulatory arm in the human biological clock, is involved in metabolic regulation. The aim was to investigate the behavioral (sleep duration, food timing, dietary intake, appetite and chronobiologic characteristics) and hormonal (plasma ghrelin and Glucagon-like peptide-1 concentrations) factors that could explain the previously reported association between the CLOCK 3111 T/C SNP and obesity.
Methods: This cross-sectional study included 403 subjects, overweight and/or obesity, aged 20- 50 years from Iran.

Objective: The aim of this study was to investigate the association of Sex Hormone Binding Globulin (SHBG) with leptin, Triidothyronine (T3), and Uncoupling Protein 2 (UCP2) in obese women with low and normal Resting Energy Expenditure (REE) and to determine the role of these factors in the regulation of REE in obese women.
Method: A total 49 subjects (25-50 years old) were selected. Anthropometric and body composition parameters and resting energy expenditure were measured.
Purpose: These days, obesity threatens the health for which one of the main interventions is calorie restriction (CR). Due to the difficulty of compliance with this treatment, CR mimetics such as resveratrol (RSV) have been considered. The present study compared the effects of RSV and CR on hypothalamic remodeling in a diet-switching experiment.
View Article and Find Full Text PDFObjective: Adult hypothalamic neurogenesis has been considered a central regulator of energy balance. Resveratrol (RSV), a natural polyphenol, influences the body fat mass and reduces the amount of adipose tissue. The present study was designed to evaluate the effect of RSV on dynamic of hypothalamic neurons in a diet-induced obesity model of mice.

Method: A total 49 subjects (25-50 years old) were selected. Anthropometric measurements, body composition, and resting energy expenditure were measured.
Obesity and depression are likely to interact mutually, which makes it unclear whether obesity causes depression or depression leads to obesity, and how the genotypes have a role in obesity and depression. This cross- sectional study was conducted on a sample of 400 individuals from the participants in the third phase of the comprehensive Iranian Multicenter Osteoporosis Study (IMOS). Anthropometric measurements and depression were assessed.

One of the key regulators of energy balance is uncoupling protein2 (UCP2), a transporter protein presents in mitochondrial inner membrane.

Methods: Seventy-five C57BL/6J male mice were given free access to a high-fat (36% of energy from fat) diet containing corn oil plus sugar (CO + S). After 11 weeks, 15 mice were sacrificed and another 60 were divided among 4 high-fat diet groups with 30% calorie restriction (CR) for the next 12 weeks.
Objectives: Neuroprotective effect of creatine (Cr) against β-amyloid (Aβ) is reported in an in vitro study. This study investigated the effect of Cr supplementation on β-amyloid toxicity in vivo.
Materials And Methods: Thirty two, male Wistar rats were divided into 4 groups.
Background: Alzheimer disease is the main cause of dementia in middle-aged and elderly people. Considering the improving effects of creatine supplementation on cognitive performance, this study aimed to determine the effects of creatine supplementation on learning, memory, and apoptosis in an experimental model of Alzheimer's disease.
Methods: Thirty-two male Wistar rats each weighing 250±50 grams were divided into four groups.
Background: Chronic ulcer is still a serious issue for diabetic patients. Diabetes is a prevalent cause of ulcer regeneration delay and (or) disruption. Since Spinacia oleracea extract contains compounds with anti-oxidative and anti-inflammatory effects, this may be effective in accelerating the healing process of ulcers, especially diabetic ulcers.

Melanocortin-4 receptor (MC4R) plays a crucial role in this system as a key receptor. Although MC4R gene as an obesity candidate gene is associated with higher BMI, only few attempts have been carried out to understand the mechanism underlying body-weight regulation.

Methods: A total of 170 hypertriglyceridemic subjects were enrolled and genotyped for Ala54Thr, Leu162Val, and intron7 polymorphism by the use of a polymerase chain reaction-restriction fragment length polymorphism method. After determination of their genotypes, the first 23 eligible subjects who were found as Ala54 carriers and the first 23 eligible Thr54 carriers were enrolled in the study and stratified for PPARα genotypes.
Glucocorticoid-induced osteoporosis (GIO) is the most common type of secondary osteoporosis. The aim of this study was to compare the efficacy of quercetin, a plant-derived flavonoid, with alendronate in the prevention of GIO. Fifty-six Sprague-Dawley rats were randomly distributed among 7 groups (8 rats per group) and treated for 6 weeks with one of the following: (i) normal saline; (ii) 40 mg methylprednisolone sodium succinate (MP)/kg body mass; (iii) MP + 40 μg alendronate/kg; (iv) MP + 50 mg quercetin/kg; (v) MP + 40 μg alendronate/kg + 50 mg quercetin/kg; (vi) MP + 150 mg quercetin/kg; and (vii) MP + 40 μg alendronate/kg + 150 mg quercetin/kg.

Polymorphism of FABP2 and PPARα may influence plasma levels of fatty acids in those who take supplemental eicosapentaenoic acid (EPA). The purpose of this study was to study the potential associations between the Ala54/Thr polymorphism in FABP2 protein and the Leu162/Val in exon 5 and G/C in intron 7 of PPARα with plasma fatty acids composition after EPA supplementation.
