Numerous studies have indicated that low levels of serum adiponectin are linked with the development of various chronic diseases. While some recent research has suggested that soy has a positive impact on serum adiponectin levels, the results are inconsistent. Therefore, we aim to conduct a thorough systematic review and meta-analysis of randomized controlled trials (RCTs) that investigate the effects of soy on serum adiponectin levels in adults.

Proper nutrition plays a vital role in modulating oxidative status. There is an increasing popularity of plant-based dietary patterns among athletes. Therefore, the present study aimed to determine the plant-based diet index (PDI) score among male footballers and their non-athlete controls, as well as its relationship with oxidative biomarkers by evaluating the urinary excretion of F-isoprostane (F-IP) and 8-hydroxy-2'-deoxyguanosine (8-OHdG).

We aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to examine the effect of cumin supplementation on markers of glycemic control in adults. A comprehensive literature search was conducted up from inception to November 2020 on PubMed, Scopus, Web of Sciences, and Cochrane electronic databases. Studies that compared the effect of cumin with placebo on fasting blood sugar (FBS), serum insulin, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) index in adults were considered eligible.

This meta-analysis was designed to determine the effect of quinoa seed on cardiovascular disease (CVD) risk factors in adults. PubMed, Scopus, ISI Web of Science, and Cochrane library were searched electronically from their inception to February 2020 to identify eligible RCTs. We calculated the pooled estimates of weighted mean differences (WMDs) and their 95% confidence intervals (CIs) by using random-effects models.

Article Synopsis
  • Colorectal cancer (CRC) is a significant global health issue, and certain amino acids, particularly arginine, may have a positive impact on improving CRC and its related complications.
  • In a systematic review of nine human studies from various databases, most findings indicated that higher arginine intake is linked to better outcomes in CRC.
  • The suggested mechanism behind these benefits includes increased nitric oxide production from arginine, which may help reduce tumor cell proliferation and enhance immune function post-surgery, although further well-designed research is needed for conclusive evidence.

Background And Objectives: The impetus for the current study was to evaluate the efficacy of propolis supplementation on markers of glycemic status in adults with type 2 diabetes mellitus (T2DM).

Methods: A comprehensive search was conducted in PubMed, Scopus, Cochrane Library, Web of Science, and Google Scholar up to August 2018, identifying randomized controlled trials investigating the effect of propolis supplementation on glycemic markers in adults with T2DM. Cochrane Collaboration tool was used to evaluate the risk of bias assessment.

Background: Restless leg syndrome prevalence is high among the patients undergoing hemodialysis. Due to several side effects of medicational treatments, the patients prefer non-medicational methods. Therefore, the present study aimed to investigate the effects of two methods of reflexology and stretching exercises on the severity of restless leg syndrome among patients undergoing hemodialysis.

Background: It is well accepted that skeletal muscle conforms to exercise stimulus by increasing capillary density and angiogenesis, but there is less evidence regarding the effect of resistance training on capillary density in flexor hallucis longus (FHL) and soleus muscle.

Objectives: In this study, we evaluated the effect of resistance training on capillary density around soleus and FHL muscles in type 1 diabetic rats.

Materials And Methods: Thirty-six male rats were divided into four groups: (1) control; (2) diabetic; (3) diabetic trained and (4) control trained (n = 9 each).

Background: Spiritual well-being is well-recognized as a factor that affects cancer patients' quality of life, quality of care, and satisfaction. There is evidence that supports the fact that patients' spiritual needs are associated with better quality of care, higher hospice utilization, and less aggressive care at the end of life. However, few studies have examined the Spiritual well-being (SWB) in cancer patients.

Background: Athletes use flavonoids as antioxidant to enhance endurance and physical performance. In vitro data indicate flavonoids have antioxidative and antiinflammatory functions but data in human studies are limited. The aim of this study was to determine the effects of a 2-month flavonoid quercetin supplementation on oxidative stress and inflammatory biomarkers in nonprofessional athletes with regular exercise.

Background: Asymmetric dimethylarginine (ADMA) has a predominant role in progression of some cardiovascular diseases, including diabetes. It interferes with L-arginine in production of nitric oxide (NO) by inhibition of NO synthase. The purpose of this study was to evaluate the effect of resistance training on plasma NO and ADMA concentrations in type 1 diabetic male rats.

Background: Flavonoids comprise a large group of plant metabolites, 6,000 of which have been identified to date. Some studies have shown the increased aerobic performance and maximal oxygen consumption (VO(2max)) and therefore fitness following quercetin intake as a result of elevated number of intracellular mitochondria caused by the flavonoid.

Methods: This double-blind clinical trial comprised 60 male students having an athletic history of at least 3 years.
