Metabolic syndrome is a complex disorder with high socioeconomic costs and a high global prevalence. The serum concentrations of some trace elements are higher in people with metabolic syndrome compared to normal individuals. Curcumin is derived from turmeric and has antioxidant and anti-inflammatory properties. Curcumin may therefore have a potential role in the management of cardiovascular risk. The aim of this study was to investigate the effects of curcumin on serum copper (Cu), zinc (Zn), and Zn/Cu ratio levels in patients with metabolic syndrome...

Osteoporosis is one of the major health problems worldwide. It is characterized by increased bone fragility and loss of bone matter due to the action of osteoclast cells, which are associated with modified hormone levels and factors such as aging. Bisphosphonates are the primary treatment for osteoporosis. Apart from bisphosphonates, hormone therapy, calcitonin treatment, selective estrogen receptor modulators (SERMs), and strontium ranelate (SR) are some of the other treatments available for osteoporosis. However, these treatments have some side effects, such as oily skin, fluid retention, nausea, long-term toxicity, and even prostate cancer in males, and thus natural therapies that incur fewer side effects are sought...

Glutamine and alanine are lipogenic and could prevent the effects of resistance training (RT) in reducing adiposity and modulating lipid profile. Thus, we aimed to investigate the effects of RT and glutamine and alanine supplementation, in their free or conjugated form, on relative epididymal adipose tissue (EAT) and brown adipose tissue (BAT) weight, plasma lipid profile, and adipokines in EAT. Thirty Wistar rats, aged two months, were distributed into five groups: control (CTRL), trained (TRN), trained and supplemented with alanine (ALA), glutamine and alanine in their free form (GLN+ALA), or L-alanyl-L-glutamine (DIP)...

Type 2 diabetes (T2D) is characterized by insufficient insulin secretion by the pancreatic beta cells and insulin resistance in liver, skeletal muscle, and white adipose tissue. Adipose tissue plays a major role in glucose homeostasis and lipid metabolism. Dietary antioxidants such as resveratrol and mangiferin may offer some protection against the early stage of diabetes mellitus. Therefore, an attempt has been made to investigate the effects of resveratrol and mangiferin on biochemical parameters and molecular mechanism of PPARγ and FALDH gene expression in adipose tissue of streptozotocin- (STZ-) nicotinamide- (NA-) induced diabetic rats...

Parkinson's disease (PD) is the second-most common neurodegenerative disorder and is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta. Oxidative stress has also been linked with the progression of PD, hence the involvement of a natural plant product could offer neuroprotection. The present study deals with the effect of genistein on the transgenic flies expressing normal human alpha synuclein panneurally. The PD flies were exposed to 10, 20, 30, and 40 µM of genistein (mixed in diet) for 24 days...

The objective of this review is to summarize the effect of commonly used mushrooms (particularly Pleurotus ostreatus or oyster mushroom, Agaricus bisporus or Button mushroom, Lentimula edodes or shiitake mushroom, and Ganoderma lucidum or reishi mushroom) in poultry diets on performance of broilers and layers. It can be concluded from different studies that mushrooms and their polysaccharides can play important roles in poultry production: (1) Polysaccharides in mushrooms may act as immune enhancers or immunomodulators and show antibacterial, antiviral, antiparasitic bioactivities; (2) phenolic compounds of mushrooms may act as antioxidants; (3) mushrooms in broiler's diet may be used as growth promoters as an alternative to antibiotics; (4) mushrooms in the diet may improve egg production and quality; (5) mushrooms may be used as a safe and effective alternative for inducing molt, enhancing immunity, reducing Salmonella growth, and returning to egg production...

The present study aimed to evaluate the protective effect of fresh fruit juice of Opuntia dillenii Haw. (FJOD) on acetic acid-induced ulcerative colitis in rats. Fresh FJOD (2.5 and 5 ml/kg) and sulfasalazine (100 mg/kg) were given orally for seven consecutive days prior to colitis induction on the eighth day by intrarectal acetic acid (4% v/v) administration. Macroscopic, clinical activity scoring, biochemical, and histopathological examinations of colon were used to assess colonic damage. FJOD and sulfasalazine treatment significantly attenuated the macroscopic damage, clinical activity score, and wet weight of the colon when compared to disease control and further showed significantly reduced levels of myeloperoxidase, malondialdehyde, and serum lactate dehydrogenase and enhanced colonic levels of reduced glutathione...

Metabolic syndrome (MetS) is associated with an increased risk of cardiovascular disease and diabetes mellitus. Inflammation and oxidant stress are features of MetS that can enhance the expression and release of heat shock proteins (Hsps), including the small heat shock protein, Hsp 27, and that may subsequently lead to the production of Hsp27 antibodies (anti-Hsp 27). Curcumin is an anti-inflammatory and antioxidant phytochemical that may ameliorate these features of MetS. We investigated the effects of unformulated curcumin and phospholipidated curcumin on antibody titers to heat shock protein 27 (anti-Hsp 27) in patients with MetS...

Tuberculosis (TB) has become the most important infectious disease to see resurgence worldwide. In 2014, there were 9.6 million documented cases worldwide with a mortality of almost 1.5 million (Global Tuberculosis Report 2014). One of the Millennium Development Goals set by the United Nations was the reversal of the TB epidemic, which has been achieved worldwide with an 18% lower incidence of TB globally compared to the incidence in the year 2000. Though efficient intervention has brought down the relative incidence and mortality of TB globally, the fact remains that one third of the world population has latent TB infection, and 10% of people with latent TB infection develop active TB at some point in their life (The Facts about Tuberculosis 1995)...

Excessive calorie intake is generally accepted as a primary cause of metabolic syndrome, and therefore a well-balanced diet and moderate exercise can be expected to be the most effective measures to avoid the disorder of energy utilization and storage. Furthermore, as any other way to improve the disorder of energy balance, it may be effective to delay and lower the digestion and/or absorption of energy sources, lipids, and carbohydrates. As a primary screening of effective substances to delay and lower the digestion and absorption processes among natural materials, the protein-deprived extract was prepared from blue-green algae Spirulina platensis, and the effect of this extract on lipase and α-glucosidase activities was examined...

Cycloferin is an extract of the chemicals from the Cyclopia species, which grows only in small areas in the southwest and southeast of South Africa and has been consumed traditionally as a nourishing tea to treat numerous health issues and illnesses. Previous studies report that some of the active compounds in Cycloferin, such as pinitol (a modified sugar) and mangiferin (a glucoside), may reduce blood sugar levels and therefore may be used as a treatment for diabetes. Mangiferin, in particular, has been shown to stimulate carbohydrate oxidation and alleviate some effects of insulin resistance and hyperglycemia...
