The impact of exercise on growth factors in postmenopausal women: a systematic review and meta-analysis.

Background: Aging results in many changes in health status, body composition, muscle strength, and, ultimately, functional capacity. These changes coincide with significant alterations in the endocrine system, such as insulin-like growth factor-1 (IGF-1) and IGF-binding proteins (IGFBPs), and may be associated with many symptoms of aging. The objectives of this study is to investigate the potential influence of different types of exercise, such as resistance training and aerobic training, on IGF-1 and IGFBP-3 levels in postmenopausal women.

Creatine supplementation effect on recovery following exercise-induced muscle damage: A systematic review and meta-analysis of randomized controlled trials.

Exercise-induced muscle damage (EIMD) causes increased soreness, impaired function of muscles, and reductions in muscle force. Accumulating evidence suggests the beneficial effects of creatine on EIMD. Nevertheless, outcomes differ substantially across various articles.

Association between dietary glycemic index and liver enzymes level among apparently healthy adults.

Objective: The previous studies have revealed that there is a link between dietary glycemic index and lipid profile in overweight and obesity. The aim of study was to investigate whether the glycemic index is associated with liver enzymes.

Method: Anthropometric and biochemical parameters were measured in 265 participants.

Metabolic Syndrome Prevalence among Armed Forces Personnel (Military Personnel and Police Officers): A Systematic Review and Meta-Analysis.

Introduction: Metabolic syndrome (MetS) is closely linked to type 2 diabetes and cardiovascular disease. Various studies have reported the prevalence of MetS in different armed forces personnel in different countries. However, performing a systematic review and meta-analysis on this subject seems necessary.

Interactions between vitamin D binding protein variants and major dietary patterns on the odds of metabolic syndrome and its components in apparently healthy adults.

Background: Recent studies have shown that the risks of chronic diseases resulting from high-risk alleles, such as cardiovascular diseases and metabolic syndrome (MetS), can be affected by various dietary patterns. Among the genes affected by environmental factors are those associated with vitamin D binding protein (DBP).

Methods: This cross-sectional study was conducted on a random sample of 265 apparently healthy adults aged 18-50.

The Association between Vitamin D Deficiency and variants of Vitamin D Binding protein gene among Healthy Iranian Adults.

The high prevalence of vitamin D deficiency may be due to both genetic and environment factors. The aim of this study was to demonstrate that vitamin D deficiency may be due to variants of vitamin D binding protein ( among otherwise healthy Iranian adults. This cross-sectional study was conducted on 265 healthy adults in Tehran.

Dietary patterns interact with chromosome 9p21 rs1333048 polymorphism on the risk of obesity and cardiovascular risk factors in apparently healthy Tehrani adults.

Purpose: Gene-dietary patterns may contribute to determining body composition and related biochemical indices. The aim of this study was to evaluate interactions between rs1333048 polymorphism and major dietary patterns on body fat percentage, general and central obesity, and related biochemical measurements.

Methods: This cross-sectional study was conducted on 265 healthy Tehrani adults with mean age of 35 years (47.

Interaction between a variant of chromosome 9p21.3 locus and diet antioxidant capacity on metabolic syndrome in Tehrani adults.

Background: Genome-wide association studies have shown that risk alleles on chromosome 9p21.3 locus, are associated with increasing the risk of cardiovascular diseases (CVDs). Several epidemiological studies have found that metabolic syndrome (MetS) is associated with CVDs.

A High-Protein/Low-Fat Diet May Interact with Vitamin D-Binding Protein Gene Variants to Moderate the Risk of Depression in Apparently Healthy Adults.

Background: Recent studies have shown that depression is inversely correlated with high protein and low fat intake and positively correlated with vitamin D-binding protein (VDBP). Therefore, the aim of this study was to examine the interaction between protein/fat dietary patterns and VDBP genotypes with regard to the risk of depression in apparently healthy adults who have not been diagnosed with any chronic disease.

Methods: In this study, 265 individuals (126 males and 139 females) aged 18-55 years were recruited from the communities of central and west Tehran based on convenience sampling.

Associations of vitamin D status and metabolic dyslipidemia and hypertriglyceridemic waist phenotype in apparently healthy adults.

Background: Recent studies have shown that Vitamin D deficiency is very common globally. Vitamin D deficiency is associated with lipid metabolism. A relationship between vitamin D levels and waist circumference (WC) has been observed.

The Effects of Beta-Hydroxy-Beta-Methylbutyrate Supplementation on Recovery Following Exercise-Induced Muscle Damage: A Systematic Review and Meta-Analysis.

Background: Growing evidence suggests beta-hydroxy-beta-methylbutyrate's (HMB) positive effects on recovery following exercise-induced muscle damage (EIMD). However, findings vary substantially across studies.

Objective: A meta-analysis of randomized controlled trials was conducted to assess the effects of HMB supplementation on recovery following EIMD by assessing indirect markers of muscle damage, namely creatine kinase (CK) and lactate dehydrogenase (LDH) serum levels among healthy participants.

The Association Between Dietary Glycemic Index and Glycemic Load and a Body Shape and Fat Distribution Among Apparently Healthy Iranian Adults.

Objective: The role of dietary glycemic index (GI) and glycemic load (GL) in the development of obesity has been debated globally. The relationship with body shape and fat distribution was examined in this cross-sectional association study among apparently healthy Iranian adults.

Methods And Materials: A study population of 265 (126 males and 139 females) aged 18-55 years participated in this cross-sectional study from the communities of Tehran based on cluster sampling.

The Association between Fruit and Vegetable Intake and Liver Enzymes (Aspartate and Alanine Transaminases) in Tehran, Iran.

Background: Intake of fiber and antioxidants and following hypocaloric diets has beneficial effects on reduction of the liver enzymes. Fruits and vegetables are low in calorie and rich in fiber and antioxidants. There are few studies about special dietary effects on liver function.

Effect of whey protein supplementation on long and short term appetite: A meta-analysis of randomized controlled trials.

Specific components of dairy, such as whey proteins may have beneficial effects on body composition by suppressing appetite, although the findings of existing studies have been inconsistent. Therefore, a meta-analysis of randomized controlled trials was performed to investigate effect of whey protein supplementation on long and short term appetite. A systematic search was conducted to identify eligible publications.

Branched-chain amino acid supplementation and exercise-induced muscle damage in exercise recovery: A meta-analysis of randomized clinical trials.

Objective: Accumulating evidence suggests positive effects of branched-chain amino acids (BCAAs) on moderate muscle damage. However, findings vary substantially across studies. The aim of this review was to examine the effect of BCAAs on recovery following exercise-induced muscle damage.
