UNLABELLED The aim of our study was to investigate the effects of atorvastatin on serum levels of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (apoA1), apolipoprotein B (apoB) and lipoprotein (a) in patients with primary hyperlipidemia and established coronary heart disease. MATERIAL AND METHODS A group of 96 patients (pts), of both ...

Measurement of serum alanine aminotransferase (ALT) is a common, readily available, and inexpensive laboratory assay in clinical practice. ALT activity is not only measured to detect liver disease, but also to monitor overall health. ALT activity is influenced by various factors, including viral hepatitis, alcohol consumption, and medication. Recently, the impact of metabolic abnormalities on A...

The genomic organisation of two abundant larval transcript (alt) genes from the filarial nematode Brugia malayi has been defined. The products of these genes are 78% identical in amino acid sequence, and are highly expressed in a stage-specific manner by mosquito-borne infective larvae. alt-1 is present as two near-identical copies organised in an inverted repeat of approximately 7.6 kb, occupy...

In this thesis, we study the preprocessing phase of the ALT algorithm. ALT is a well known preprocessing-based speed-up technique for Dijkstra’s algorithm, which allows fast computations of shortest paths in large scale road networks. The preprocessing of the ALT algorithm has some degree of freedom, in that it must select a subset of nodes in the graph, called landmarks, that fulfill a special...

Telomeres protect chromosome termini to maintain genomic stability and regulate cellular lifespan. Maintenance of telomere length is required for neoplastic cells after the acquisition of mutations that deregulate cell cycle control and increase cellular proliferation, and can occur through expression of the enzyme telomerase or in a telomerase-independent manner termed alternative lengthening ...

Human cancer cells maintain telomeres by telomerase activity (TA) or by alternative lengthening of telomeres (ALT). We proposed to define the prevalence of the two telomere maintenance mechanisms (TMM), to assess their association with histology, and to compare their prognostic relevance in a series of 93 patients with liposarcoma. ALT was detected by assaying ALT-associated promyelocytic leuke...

The unlimited proliferation of cancer cells requires a mechanism to prevent telomere shortening. Alternative Lengthening of Telomeres (ALT) is an homologous recombination-mediated mechanism of telomere elongation used in tumors, including osteosarcomas, soft tissue sarcoma subtypes, and glial brain tumors. Mutations in the ATRX/DAXX chromatin remodeling complex have been reported in tumors and ...

Significant liver disease has been reported in chronic hepatitis B patients with normal alanine aminotransferase (ALT) but most studies performed biopsies on selected patients only. The aims of this study were to determine the rate of liver biopsy, characteristics of patients who underwent a biopsy and factors associated with significant liver disease in a cohort of such patients. Records of pa...

In this study, a miniaturized biosensor based on permselective polymer layers (overoxidized polypyrrole (Ppy) and Nafion(®)) modified and enzyme (glutamate oxidase (GlutOx)) immobilized micro-platinum wire electrode for the detection of alanine aminotransferase (ALT) was fabricated. The proposed ALT biosensor was measured electrochemically by constant potential amperometry at +0.7 V vs. Ag/AgCl...
