Metallothioneins (MTs) are low weight proteins involved in several key cellular processes such as metal ions homeostasis, detoxification and scavenging of free radicals. Four groups of MTs are distinguished: MT-1, MT-2, MT-3 and MT-4. Regardless of the type, MTs are characterized by high content of cysteine, responsible for their biological properties such as binding of relevant zinc and copper...

Objective: Study was conducted to observe the relationship of ions with lipid profile and protein content of hypertensive patients. Methods: Lipid profile, ions and serum and urinary proteins were studied in patients with hypertension and compared with normal subjects. Results: Serum cholesterol, triglyceride and LDL-chol were significantly increased, whereas the level of HDL-cholesterol was si...

This work deals with geopolymers based on local Jordanian resources, namely, kaolin and zeoltitic (phillipsite) tuff. The geopolymers were prepared from these two materials by a reaction with an alkali solution at 80oC. The research group of the present work has demonstrated in previous work that addition of zeolitic tuff to kaolin based-geopolymers increases the adsorption capacity toward Cu(I...
