Introduction: In recent years the relationship between electromagnetic fields and coronary artery disease is attracted a considerable attention. Low density lipoprotein (LDL) oxidation is the initial step in the development of atherosclerosis. Paraoxonase1 (PON1) protects LDL and High density lipoprotein (HDL) against oxidative processes, thus preventing the formation of atherogenic (oxidized-L...

In this paper we propose a new adaptation technique for improved text-independent speaker verification with limited amounts of training data using Gaussian mixture models (GMMs). The technique, referred to as probabilistic subspace adaptation (PSA), employs a probabilistic subspace description of how a client’s parametric representation (i.e. GMM) is allowed to vary. Our technique is compared t...

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...
