According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields. Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low ...
background: the human body contains of different tissues and cavities with different physical and radiological properties. most important among these are tissues and cavities that are radiologically different from water, including lungs, sinuses and bones. gel dosimetry provides a unique feature to display dose distributions occurring in clinical radiation therapy in three dimensions. materials...
the non-enzymatic carbamylation of low density lipoprotein (ldl) is a naturally occurring chemical modification of apolipoprotein b as a result of condensation between lysine residues and cyanate derived from urea. carbamylated ldl is poorly recognized by ldl receptors and initiates different processes that can be considered proatherogenic. thus, ldl carbamylation may contribute to the increase...
the oxidative modification of low density lipoprotein (ldl) may play an important role in atherogenesis. antioxidants that can prevent ldl oxidation may act as antiatherogens. our understanding of the mechanism of ldl oxidation and factors that determine its susceptibility to oxidation is still incomplete. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper...
background: it is well established that oxidative modification of low density lipoprotein (ldl) plays a causal role in human atherogenesis and the risk of atherosclerosis is increased in patients with diabetes mellitus. we examined the in vitro effect of glucose on native and glycated ldl oxidation using copper ion dependent oxidation system. methods: in this study, ldl was isolated from plasma...
Transplantation of eelgrass Zostera marina has become a promising restoration tool since natural recolonisation during the last century failed after massive mortality, due to a combination of a wasting disease outbreak and a sequence of human impacts. We studied the interactive effects of planting density and hydrodynamic exposure on the survival of transplants of an annual population of intert...
the seasonal diversity and distribution of microphytes and macrophytes in 40 artificial irrigationponds constructed in a semi-arid region, and the most suitable conditions to maintain these enclaves asbiodiversity spots were studied for the first time. a total of 104 species were detected. bacillariophyta,cyanobacteria and chlorophyta dominated both pelagic and benthic microphytic communities, ...
A comparison was made of the hardness of Z250 and Esthet-X composites light cured with different light sources. Cavities (3 mm diameter x 6 mm deep) were prepared in 240 bovine incisors. The composite was bulk inserted and light-cured using halogen light, LED or xenon plasma arc (PAC) with different irradiances and exposure times, maintaining the same energy density. The specimens were stored i...
Proprotein convertase subtilisin/kexin type 9 (PCSK9) has emerged as an attractive therapeutic target for cardiovascular disease. Monoclonal antibodies (mAbs) that bind PCSK9 and prevent PCSK9:low-density lipoprotein receptor complex formation reduce serum low-density lipoprotein-cholesterol (LDL-C) in vivo. PCSK9mediated lysosomal degradation of bound mAb, however, dramatically reduces mAb exp...
