Ammonia Sensing and Cytotoxicity of the Biosynthesized Silver Nanoparticle by Arabic Gum (AG).

Background: The green synthesizing procedure of Silver nanoparticles (AgNPs) has been performed through the usage of a natural polysaccharide; Arabic gum (AG) as a stabilizing/ capping agent. For characterization of AgNPs, TEM, particle size analyzer and UV-Vis were used.

Methods: The aim of our project was to identify biosynthesized AgNPs for sensing ammonia and to explore its toxicity on Neuro-2A cells.

Vitamin D status in female students and its relation to calcium metabolism markers, lifestyles, and polymorphism in vitamin D receptor.

Background: Vitamin D is essential for maintiiining bone health and growth throughout life. Vitamin D deficiency not only leads to bone metabolic diseases in children and adults but may increase the risk of many chronic diseases. The aim of this study was to evaluate the prevalence of vitamin D deficiency and its relation with vitamin D receptor (VDR) gene polymorphism.

Effects of body electroacupuncture on plasma leptin concentrations in obese and overweight people in Iran: a randomized controlled trial.

Background: The prevalence of obesity, a major public health problem, is increasing in many countries, including Iran. Leptin, a peptide hormone that is released from adipocytes, is a major factor in appetite regulation. Levels of plasma leptin increase with increased body fat mass (BFM).

Effects of auricular acupressure combined with low-calorie diet on the leptin hormone in obese and overweight Iranian individuals.

Background: Human leptin is a peptide hormone that is released from white adipocytes. The absence of leptin or its receptor leads to uncontrolled food intake, leading to obesity. In the present work, the effects of auricular acupressure combined with low-calorie diet on the leptin hormone level were investigated.
