Introduction: Zinc deficiency is a health problem in many communities, especially among children because of growth spurt. Zinc deficiency can causegrowth limitation, delay in sexuel maturity, behavior disorders and abnormalities of immune system,susceptibility to respiratory and gasterointestinal infections and impairment of taste and smell perception. Material and Method: One of the methods ...
OBJECT Recent evidence suggests that a glioma stem cell subpopulation may determine the biological behavior of tumors, including resistance to therapy. To investigate this hypothesis, the authors examined varying grades of gliomas for stem cell marker expressions and histopathological changes between primary and recurrent tumors. METHODS Tumor samples were collected during surgery from 70 pat...

Introduction: Meningioma is usually a benign brain tumor, but sometimes with aggressive course. The aim of this study was to assess the ability of 201Tl Brain SPECT to differentiate the pathologic grade of meningioma preoperatively. Methods: Thirty lesions in 28 patients were evaluated in this study. Early (20 minutes) and late (3 hours) brain SPECT images were performed and early u...
Bioreduction of ferric iron-rich wastes is a rapidly emerging technology for the extraction/ recovery of metals from low-grade ores and metallurgical wastes. However, despite studies being successful, they have only been demonstrated at laboratory scale and issues relating to economic, industrial scale application have yet to be studied. Using bioreduction as a pre-treatment to increase recover...
le mythe gémellaire a pour fonction de montrer la dualité dans l’homme. dualité qui est la conséquence de rivalité, de jalousie, d’amour et de haine, mais cette dualité constitue les notions de la mortalité et l’immortalité. michel tournier actualise le thème de la dualité et lui procure un contenu nouveau. prise dans les paradigmes astreignants, l’histoire de jean-paul commençait par de sombre...
In both cow's milk and human milk, zinc was associated with proteins of high molecular weight (greater than 100 000), as judged by analysis with Sephadex G-75. Precipitation of the casein at pH 4.6 and filtration of the resultant acid whey on Sephadex G-25 led, however, to the recovery of about 90% of the zinc as a compound of low molecular weight, which was tentatively identified as zinc citra...
Background: Zinc has significant effects on structural and functional activities of many proteins and enzymes involved in biological activities, especially the regulation of immune-system. Symptoms of zinc toxicity include nausea/vomiting, fever, cough, diarrhea, fatigue, neuropathy, and dehydration. Further signs include growth retardation, altered iron function, anemia, copper deficiency, ...
Jachymski [ Proc. Amer. Math. Soc., 136 (2008), 1359-1373] gave modified version of a Banach fixed point theorem on a metric space endowed with a graph. In the present paper, (G, Φ)-graphic contractions have been de ned by using a comparison function and studied the existence of fixed points. Also, Hardy-Rogers G-contraction have been introduced and some fixed point theorems have been proved. S...
