Background and aim: Deficiency of zinc -as a necessary trace element-causes exacerbation of acne and development of acne lesions. Also zinc has been used in acne treatment. In this study serum zinc level was evaluated in severe acne cases. Materials and methods: Severe acne cases as well as sex and age matched controls were selected from dermatology clinics of Imam Reza and Qaem Hospitals durin...

This study was conducted to determine the serum concentration of zinc in children with acute pyelonephritis. Serum zinc levels of 60 children with acute pyelonephritis and 60 healthy children were compared. Acute pyelonephritis was diagnosed using Tc-99m dimercaptosuccinic acid (DMSA) renal scan. Serum zinc levels were measured by the atomic absorption flame spectrophotometry. The levels in que...

a novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. the nanocomposite was prepared using a domestic microwave oven. the prepared nanocomposites have been characterized by fourier transform infrared (ftir) spectroscopy, x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and uv- visible spectroscopy. the crystalline properties...

AIM This study evaluated serum levels of zinc in patient with CD compare to healthy subjects. BACKGROUND Celiac disease (CD) is characterized by small intestinal malabsorption of nutrients as a consequence of ingestion of wheat gluten. Zinc is an essential trace element that it has vital biological functions. PATIENTS AND METHODS Sera of 30 celiac cases and 30 healthy normal cohorts as cont...

The crystal structure of human endostatin reveals a zinc-binding site. Atomic absorption spectroscopy indicates that zinc is a constituent of both human and murine endostatin in solution. The human endostatin zinc site is formed by three histidines at the N terminus, residues 1, 3, and, 11, and an aspartic acid at residue 76. The N-terminal loop ordered around the zinc makes a dimeric contact i...

Because trace minerals are important not only for human nutrition but for plant nutrition as well, plant breeding holds great promise for making a significant, sustainable, low-cost contribution to the reduction of micronutrient deficiencies in humans. It may also have important spinoff effects for increasing farm productivity in developing countries in an environmentally beneficial way. This a...

PROJECT Data about the influence of aging on urinary excretion of iron and zinc are scarce. The objective of the present study was to compare the concentration of zinc and iron in the urine of healthy elderly subjects and younger adults. PROCEDURE Seven healthy elderly subjects and seven younger adults were selected and submitted to biochemical, clinical, and nutritional tests. After a fastin...

background: there have been very few studies, with contradictory results, on the zinc status of children and adolescents with type-1 diabetes mellitus. the objective of this cross-sectional study was to determine zinc status based on the serum zinc concentration in type-1 diabetic children and adolescents and compare it with that of healthy controls. methods: thirty children and adolescents wit...

introduction: neonatal jaundice is the most common cause of hospitalization.animal study demonstrated a decrease in serum bililrubin level after zinc treatment in hyperbilirubinemic rats. the objective of this study was the investigation of serum zinc level in the neonates with idiopatic .   materials and methods: a case-control study was undertaken on 263 neonates in a neonatal intensive care ...
