Some Trace Elements' Level in Alopecia Areata

Background : Alopecia areata (AA) is a non-scarring, inflammatory, hair loss disease with an unpredictable course. It is commonly manifested by patchy areas of complete hair loss on the scalp and other hair-bearing areas in the body that can progress to complete loss of all body hair. AA is a T-cell-mediated autoimmune condition that is most likely to occur in genetically predisposed individual...

Instrumental Neutron Activation Analysis of Trace Elements in Some Food Spices Consumed In Tehran, Iran

Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA) was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human healt...

Synthesis of Hydroxyapatite Containing some Trace Amounts Elements in Simulated Body Fluids

Spherical-like hydroxyapatite (HA, Ca10(PO4)6(OH)2) particles were prepared by the co-precipitation method in a simulated physiological environment. The effect of calcining temperature, calcining time and the Ca/P ratio of the initial feeding on the morphology and crystallinity of HA were investigated in detail. Interestingly, wh...

The status of antioxidants, malondialdehyde and some trace elements in serum of patients with breast cancer

Background: There are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. The aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. Methods: Fifty-eight breast cancers patients par...
