Let n and q be given integers and X a finite set with n elements. The following theorem is proved for n > n0(q). The family of all q-element subsets of X can be partitioned into disjoint pairs (except possibly one if (n q ) is odd), so that |A1∩A2|+ |B1 ∩B2| ≤ q, |A1 ∩B2|+ |B1 ∩A2| ≤ q holds for any two such pairs {A1, B1} and {A2, B2}. This is a sharpening of a theorem in [2]. It is also shown...

The physiologic activator of factor X consists of a complex of factor IXa, factor VIIIa, Ca(2+) and a suitable phospholipid surface. In one study, helix 330 (162 in chymotrypsin) of the protease domain of factor IXa was implicated in binding to factor VIIIa. In another study, residues 558-565 of the A2 subunit of factor VIIIa were implicated in binding to factor IXa. We now provide data, which ...

Abstract New three iterative methods in order to solve non-linear problems for PV cell equations with various data of R (load resistance) have been investigated. A series hybrid algorithms Newton’s, Predictor-Corrector Type (A1), (A2) and Dekker’s are implemented obtain approximate solutions functions. The purpose the present paper is analysis on numerical comparison between standard Newton’s a...

T he properties of large conductance C a2+-dependent K + channels in smooth muscle cells (smc) isolated from norm al and atherosclerotic hum an aorta were studied using the patch-clam p technique. It was shown tha t smc from norm al hum an aorta possess a homogeneous population of norm al C a2+-dependent K + channels. In atherosclerotic aorta two kinetically different types of these channels co...

Thromboxane A2 (TBXA2) is a potent vasoconstrictor in cerebral circulation and is a known contributor to the pathogenesis of cerebral infarction. Thromboxane A2 synthase 1 (TBXAS1) and thromboxane A2 receptors (TBXA2R) are key components in TBXA2 function. We examined whether genetic variants in TBXA2R and TBXAS1 are risk factors for cerebral infarction by genotyping 453 Korean patients with no...

Phospholipase A2 (EC 3.1.1.4) is a key enzyme in inflammation and is thought to play an important part in inflammatory diseases of the gastrointestinal tract. To investigate the nature and regulation of phospholipase A2 activity in the gastrointestinal mucosa, the distribution of messenger ribonucleic acid (mRNA) for group II phospholipase A2 in various parts of the rat gastrointestinal tract w...

Manin’s conjecture is proved for a split del Pezzo surface of degree 5 with a singularity of type A2.

Vancomycin-resistant Enterococcus faecium (VREF) in human infections mostly belong to the high-risk, epidemic, clonal complex-17 (CC17) group. Treatment limitation and high conjugation frequency makes it dominant in hospitals worldwide. We investigated positive cultures by Pulse-field gel electrophoresis (PFGE), multi locus sequence typing (MLST). DNA of two strains (A2 and C) appeared to be cl...

A cytotoxic T lymphocyte (CTL) clone generated in vitro from the peripheral blood of a healthy HLA-A2-positive individual against a synthetic p53 protein-derived wild-type peptide (L9V) was shown to kill squamous carcinoma cell lines derived from two head and neck carcinomas, which expressed mutant p53 genes, in a L9V/HLA-A2 specific and restricted fashion. Thus, the normal tolerance against en...
