The involvement of elements in the pathological process of primary hypertension has been established. The serum levels of copper, iron, zinc, sodium, potassium and calcium were studied by atomic absorption spectrophotometery and flame photometry in hypertensive and normal subjects. Serum copper and zinc levels were increased in hypertensive patients (25.5% and 14.7% respectively) as compar...

objective: considering the various evidences due to effects of trace elements on the outcome of pregnancy, we decided to assess the effect of these elements levels in maternal and cord serum on low birth weight. materials and methods: an analytical cross-sectional study was performed on 344 pregnant women in labour and their neonates in maryam, akbarabadi and vali-e-asr hospitals in tehran, ir...

background trace elements and lipids have an important role in the development of osteoporosis that is a major health problem of postmenopausal women. objectives the purpose of this study was to compare the serum levels of zinc (zn), copper (cu) and lipid profile between the postmenopausal women suffering from osteoporosis and the healthy controls. furthermore, we aimed to determine whether the...

background: pre-eclampsia along with its complications seems to be one of the major causes of maternal morbidity and mortality. despite numerous studies, the etiology of pre-eclampsia has not yet been fully elucidated. according to recent studies changes in the level of blood trace elements can be an adverse event in human and animal pregnancy. the present study determines whether maternal seru...

Electrocardiography (ECG) may be used to recognize cardiac disorders. Levels of milk production may change the serum electrolytes which its imbalance has a role in cardiac arrhythmia. Fifty high yielding and fifty low yielding Holstein dairy cows were used in this study. Electrocardiography was recorded by base-apex lead and blood samples were collected from jugular vein for measurement of seru...

background: the present study was performed to investigate the effects of trace elements particularity se, zn and cu on tumor genesis in breast cancer. methods: the inhibitory effect of se, zn and cu, on telomerase activity was analyzed in human breast tumor tissues and breast cancer (t47d) cells. tissue specimens from 24 women with benign breast disease and 32 women with breast cancer specimen...

Fingerprint signatures of circularly polarized luminescence (CPL) are observed from Staphylococcus aureus nuclease (SNase), bovine serum albumin (BSA), and insulin (Ins) labeled with europium(III) complexes containing a β-diketonate ligand, where SNase shows a virtually opposite CPL sign compared to those of BSA and Ins.

Magnesium and manganese have proved physically and functionally interchangeable in many isolated biological systems investigated in vitro. This lack of discrimination contrasts sharply with the high biological specificity exhibited by intact mammals under a large variety of conditions. The dichotomy between intact animals and their isolated systems might be due at least partially to presence vs...

Background: Psoriasis is a common and chronic inflammatory skin disease that has profound adverse effects on patients’ wellbeing. Trace elements are essential to biochemical processes in the body and are involved in immunological and inflammatory reactions such as keratinization and melanin formation. The aim of this study was to evaluate the essential metals in psoriasis in comparision with he...
