acquired bilateral longitudinal true leukonychia is a rare disorder. we present a case of a 35‑year‑old healthy woman presented with this unusual and rare manifestation. she mentioned a history of unprotected exposure to detergents and bleaching chemical agents. considering her low zinc level, she was prescribed with zinc capsules and recommended to avoid chemical substances for 6 months. durin...

Renal anemia is one of the most important complication as a cause of cardiovascular event in patients with chronic kidney disease (CKD). The status of renal anemia has been ameliorated by using recombinant human erythropoietin (EPO), however, the EPO resistant anemia is sometimes seen in high stage CKD patients. Heavy metal deficiency including zinc deficiency is one of the cause of EPO resista...

This study investigated if a marginal zinc deficiency during gestation in rats could affect fetal neural progenitor cell (NPC) proliferation through a down-regulation of the extracellular signal-regulated kinase (ERK1/2) signaling pathway. Rats were fed a marginally zinc-deficient or adequate diet from the beginning of gestation until embryonic day (E)19. The proportion of proliferating cells i...

Maternal zinc deficiency during pregnancy has been related to adverse effects on progeny, and there are data showing that mild to moderate zinc deficiency (as assessed by available indicators) is quite common in the developing world. Observational data relating zinc deficiency to adverse fetal outcome have produced conflicting results, mainly because of the lack of a valid indicator of zinc def...

Trace element deficiencies commonly encountered in Japanese infants and children are discussed. Premature birth infants have a high likelihood of developing deficiency of trace elements such as iron, zinc, and selenium, during the period of rapid growth from 2 months to 6 months of age. Breast-fed infants, in particular, are prone to develop trace element deficiency, and alopecia and dermatitis...

zink deficiency in calcareous soils of arid and semi-arid regions is a limiting factor for crop yield. bean is considered as one of sensitive plants to zinc (zn) deficiency. to study the responses of various bean genotypes to soil zinc deficiency, a greenhouse experiment was carried out. a factorial completely randomized design with three replications was conducted. the first factor was two lev...

ZINC IMBALANCE AND THE OPPORTUNITY OF ZINC SUPPLEMENTATION IN ALCOHOLICS AND DRUG USERS (Abstract): Zinc deficiency is well-documented to be associated with alcoholism, being considered a consequence of unbalanced eating habits in such patients. The present review focuses on zinc imbalance in drug addicts and on the po ssible beneficial role of zinc administration as dietary supplement. All rel...

BACKGROUND Zinc deficiency is an important problem in children, especially in developing countries. Zinc supplements have beneficial effects on multiple factors, including treatment of growth retardation and hypogonadism, and they can be used as therapeutic and prophylactic agents against infection in children. OBJECTIVE To determine the prevalence of zinc deficiency in 6-month to 12-year-old...

Zinc is a key element for growth and development. In this narrative review, we focus on the role of dietary zinc in early life (including embryo, fetus and preterm neonate), analyzing consequences of zinc deficiency and adequacy of current recommendations on dietary zinc. We performed a systematic search of articles on the role of zinc in early life. We selected and analyzed 81 studies. Results...

Zinc deficiency is an important cause of morbidity in developing countries, particularly among young children, yet little information is available on the global prevalence of zinc deficiency. A working group meeting was convened by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the International Atomic Energy Agency (IAEA), and the International Zinc Nutrition...
