Oxidative damage has been proposed as one of the possible mechanism involved in the nephrotic syndrome. Strengthening the defense system by antioxidants may provide protection against oxidative damage. Therefore, this study was carried out to investigate oxidant and antioxidant status with copper, zinc and homocysteine in nephrotic syndrome patients and the effect of antioxidants, minerals and ...

It has been suggested that one risk factor in the development of hypertension and vascular disease may be abnormal copper and zinc metabolism. In the current study we tested the hypothesis that hypertension itself may result in alterations in the metabolism of these essential elements. Dahl salt-sensitive rats were fed diets containing 0.4 or 8.0% NaCl for 32 days. At the conclusion of the stud...

than 30pg/g fresh wt., only a small proportion of the zinc was associated with the lowmolecular-weight components of fraction 111. Increases in liver zinc concentration above this value were largely accounted for by an increase in the zinc content of this fraction. No similar modifications of the zinc content of the higher-molecular-weight components (fractions I and 11) occurred in response to...

Copper and zinc are essential trace elements which play an important role in various biological processes. Along with various cytokines, glucocorticoids, glucagon and insulin, the acute-phase protein metallothionein is involved in the regulation of immune cell functions. Metallothionein is the central protein regulating zinc concentration. Zinc deficiency is often found in patients with chronic...

BACKGROUND AND OBJECTIVES Biochemical derangements of microelements although reported in oral cancer is poorly understood in oral submucous fbrosis (OSMF). Hence, the present study was carried out to estimate and compare the serum copper and zinc levels among different histopathological stages of OSMF with that of healthy controls. MATERIALS AND METHODS Thirty histopathologically diagnosed ca...

The levels ofplasma zinc, copper, caeruloplasmin, and growth hormone were determined in a group of normal people and in four groups of patients who were suffering from carcinoma of the bronchus, other forms of malignancy, chest illnesses, and diseases other than chest illness or malignancy. The plasma zinc was higher, and the plasma copper lower, in people without malignancy below the age of 30...

the sorkheh deposit in northwestern iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (ssc) mineralization. it consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish miocene sandstone and shallow-water) that overlie a thick sequence of red beds (miocene upper red formation). the host gray be...

This study focused on the modelling and experimental investigation of Copper-Zinc alloy using Split-split plot design. The effects process parameters such as percentage by volume material, material type (copper zinc), pressure their interactions mechanical properties produced copper-zinc split-split design was investigated. examined in this include; tensile strength, modulus elasticity, shear h...

The immunomodulatory and antimicrobial properties of zinc and copper have long been appreciated. In addition, these metal ions are also essential for microbial growth and survival. This presents opportunities for the host to either harness their antimicrobial properties or limit their availability as defence strategies. Recent studies have shed some light on mechanisms by which copper and zinc ...
