Groundwater is an indispensable resource for humankind and sustainable biomes functioning. Anthropogenic disturbance threatens groundwater ecosystems globally, but to which extent organisms respond stressors remains poorly understood. animals are rare, with small populations, difficult find breed in the lab, poses a main challenge assessment of their responses pollutants. Despite difficulties, ...

Copper-ion conducting gel polymer electrolyte (GPE) systems based on poly(vinyl alcohol) (PVA) and copper sulphate salt doped with glycerin as plasticizer have been synthesized by using solution casting technique. Differential scanning calorimetry (DSC) is used to examine the thermal effect of a electrolyte. With addition various quantities glycerin, in pure PVA + 20 wt% CuSO4 shows decrease va...

Though most of the metallic ions are spermicidal in action, the present investigation emphasises the spermicidal activity of anions. Among the inorganic compounds screened at 4 concentrations (0.01%, 0.1%, 1% and 5%) halides are mainly spermicidal, except NaCl, KCl & CsCl which are spermiostatic; sulphates and nitrates are mainly spermiostatic except ZnSO4 at 1% concentration and above; CuSO4, ...

BACKGROUND Scavenger receptors are thought to be involved in the recognition of oxidized low-density lipoprotein (oxLDL) and oxidized erythrocyte (oxRBC). However, there are controversies about the kind of receptors and ligands related to the binding. Macrophages lacking class A scavenger receptor show identical binding of oxRBC with wild-type ones. METHODS RBCs were oxidized with ascorbic ac...

We describe a system for gene expression in plants based on the regulation mechanism of the yeast metallothionein (MT) gene. The system consists of two elements: (i) the yeast ace1 (activating copper-MT expression) gene encoding a transcription factor under control of the cauliflower mosaic virus (CaMV) 35S RNA promoter, and (ii) a gene of interest under control of a chimeric promoter consistin...

Iron and copper, the essential trace elements accomplish their numerous relevant metabolic functions appropriately in the body. Hepcidin, ferroportin-1 and transferrin are associated with iron metabolism and their expression can be affected under different physiological or pathological conditions. The aim of the current study was to investigate the changes in hepatic gene expression of these ir...
