Course timetabling is a typical problem that all universities around the world have to face every semester. There exist a number of variants of this problem, depending on the specific requirements of the institution involved [13]. Thanks also to the international timetabling competition ITC-2007 [11], two formulations have, to some extent, lifted up to the status of “standard”. These are the so...

BACKGROUND In areas with high clarithromycin resistance, bismuth quadruple therapy (BQT) is recommended instead of clarithromycin triple therapy (CTT) as the first-line treatment for Helicobacter pylori eradication. METHODS Randomized clinical trials (RCTs) comparing BQT to CTT were identified through electronic and manual searches. A meta-analysis was performed to compare the efficacy and to...

INTRODUCTION Overexpression of matrix metalloproteinases (MMPs), particularly MMP-2 and MMP-9, has been correlated with poor prognosis in several cancer types including lung, colon and breast. Noninvasive detection of MMP expression might allow physicians to better determine when more aggressive cancer therapy is appropriate. The peptide CTT (CTTHWGFTLC) was identified as a selective inhibitor ...

Abstract Determination of accurate anti-A/-B titers is important for treatment selection in ABO-incompatible stem cell and solid-organ transplants. The standard method ABO antibody titration the conventional tube test (CTT). Dithiothreitol (DTT) commonly used to inactivate IgM component. aim this study was compare six different methods observe effectiveness DTT on estimation. A total 90 healthy...

Colon transit time measurement with radio-opaque markers is a method of studying the passage of luminal contents throughout the colon. Overall colonic transit time (CTT), as well as segmental transit times [right (RTT), left (LTT) and rectosigmoid (RSTT)], can be calculated. We hypothesize that CTT is influenced by faecal impaction when the rectum is emptied infrequently. The aim of this study ...

Gottlob, (1993, in \Proceedings, 34th IEEE Symp. on Found. Comput. Sci.," pp. 42{ 51), showed that any set recognized by polynomial-size, log-depth trees with queries to SAT is p tt-reducible to NP. Based on his technique, it is shown for any set A and any k 1, that NC k (A) AC k?1 (R NP ctt (A)), where R NP ctt (A) is the NP ctt-closure of A. As a consequence, it is shown for any class C that ...

The human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) pandemic is amongst the most important current worldwide public health threats. While much research has been focused on AIDS vaccines that target the surface viral envelope (Env) protein, including gp120 and the gp41 ectodomain, the C-terminal tail (CTT) of gp41 has received relatively little attention. Despite...
