objective(s): first, 10-bromodecanoic acid was covalently attached to all available surface primary amines of ppi g2 and g3 to increase their lipophilicity. in the subsequent step, ppis were conjugated to the alkylcarboxylate groups of alkylcarboxylate-ppi derivatives to increase the number of surface primary amines. physicochemical properties of modified ppis were determined. transfection expe...

objective: to evaluate the effect of honey supplemented to cryoprotectant medium on post-thaw sperm motility, concentration, morphology and agglutination. materials and methods: thirty semen samples were collected from 30 infertile patients. after assessment of semen analysis, semen samples were divided into 3 aliquots (0.7ml for each) and mixed with 1 ml of cryopreservation solution (g1, contr...

Nearly all the cationic molecules tested so far have been shown to reversibly block K⁺ current through the cation-selective PA63 channels of anthrax toxin in a wide nM-mM range of effective concentrations. A significant increase in channel-blocking activity of the cationic compounds was achieved when multiple copies of positively charged ligands were covalently linked to multivalent scaffolds, ...

Objective(s): First, 10-bromodecanoic acid was covalently attached to all available surface primary amines of PPI G2 and G3 to increase their lipophilicity. In the subsequent step, PPIs were conjugated to the alkylcarboxylate groups of alkylcarboxylate-PPI derivatives to increase the number of surface primary amines. Physicochemical properties of modified PPIs were determined. Transfection expe...

Given two graphs G1 and G2, the planar Ramsey number PR(G1, G2) is the smallest integer n such that every planar graph on n vertices either contains a copy of G1 or its complement contains a copy of G2. So far, the planar Ramsey numbers have been determined, when both, G1 and G2 are complete graphs or both are cycles. By combining computer search with some theoretical results, in this paper we ...

We prove that the strong product G1 G2 of G1 and G2 is Z3-flow contractible if and only if G1 G2 is not T K2, where T is a tree (we call T K2 a K4-tree). It follows that G1 G2 admits an NZ 3-flow unless G1 G2 is a K4-tree. We also give a constructive proof that yields a polynomial algorithm whose output is an NZ 3-flow if G1 G2 is not a K4-tree, and an NZ 4-flow otherwise. 2009 Wiley Periodical...

Cyclin G2 (CCNG2) is an atypical cyclin that functions to inhibit cell cycle progression and is often dysregulated in human cancers. We have previously shown that cyclin G2 is highly unstable and can be degraded through the ubiquitin/proteasome pathway. Furthermore, cyclin G2 contains a PEST domain, which has been suggested to act as a signal for degradation by multiple proteases. In this study...

OBJECTIVES Diabetes negatively affects the outcome of patients undergoing percutaneous transluminal coronary angioplasty (PTCA) or coronary surgery. However, data are lacking with respect to the impact of arterial revascularization in the diabetic population. METHODS Between 1999 and 2003, 100 of 491 diabetics underwent coronary artery bypass graft surgery (CABG) with total arterial grafting ...
