UNLABELLED Age-related macular degeneration (AMD) is the leading cause of blindness in the Western world. AMD is a multifactorial disorder but complement-mediated inflammation at the level of the retina plays a pivotal role. Oral zinc supplementation can reduce the progression of AMD but the precise mechanism of this protective effect is as yet unclear. We investigated whether zinc supplementat...
BACKGROUND In developing countries, diarrhoea causes around 500,000 child deaths annually. Zinc supplementation during acute diarrhoea is currently recommended by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF). OBJECTIVES To evaluate oral zinc supplementation for treating children with acute or persistent diarrhoea. SEARCH METHODS We searched the Cochran...
To examine the association of intestinal barrier function with vitamin A deficiency and whether supplementation of micronutrients improves intestinal function and/or linear growth, height-for-age z-score (HAZ), concentrations of serum retinol and zinc, and intestinal permeability were determined in a cross-sectional sample of 75 children in northeastern Brazil. Effects of vitamin A and suppleme...
Background: Micronutrient deficiencies of zinc and selenium can lead to thyroid dysfunction. The objective of this study was to determine the effects of zinc and selenium supplementation on thyroid function of over-weight or obese hypothyroid female patients. Methods : This was a double-blind randomized clinical trial study. Sixty-eight over-weight or obese hypothyroid female patients rando...
Inadequate nutrition and acute lower respiratory infection (ALRI) are overlapping and interrelated health problems affecting children in developing countries. Based on a critical review of randomized trials of the effect of nutritional interventions on ALRI morbidity and mortality, we concluded that: (1) zinc supplementation in zinc-deficient populations prevents about one-quarter of episodes o...
Background: Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology of diverse male infertility types, including asthenospermia. The generation of reactive oxygen species (ROS) in the male reproductive tract has become an actual concern because of their probable noxious effects, at high levels, on physical properties of sperm ...
BACKGROUND Micronutrients play an important role in immune function. To our knowledge, there have been no comprehensive studies on the role of micronutrient supplementation in children with tuberculosis. OBJECTIVE We assessed the effect of micronutrient supplementation in children treated with antituberculosis therapy (ATT). DESIGN A randomized, double-blind, placebo-controlled trial that u...
Zinc supplementation (0.8 µg/ml) in in vitro maturation (IVM) medium significantly enhances oocyte quality. In this study, we compared the development of somatic cell nuclear transfer (SCNT) embryos produced from conventional IVM (control) and zinc-supplemented IVM oocytes. A total of 1206 and 890 SCNT embryos were produced using control and zinc-supplemented oocytes, respectively, and then wer...
Zinc is an essential mineral and deficiency results in abnormal immune function and higher rates of infectious diseases. Randomized controlled trials of zinc supplementation have been conducted in children in developing countries to determine effects on infectious disease morbidity and mortality. Zinc-supplemented children have been found to have lower rates of diarrhea, pneumonia and malaria i...
Objective: The aim of this study was to evaluate the effect of zinc and magnesium supplementation on glycemic control and serum insulin in type 2 diabetic patients. Materials and Methods: In this randomized clinical trial 70 diabetic patients who referred to Yazd Diabetes Center were selected. Subjects received 500 mg/day magnesium oxide or 100 mg/day zinc sulfate randomly for 8 weeks. At th...
