Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a burden to the global healthcare system. Locally, the prevalence of MRSA in New Zealand has increased significantly over the last 10 years underscoring the urgency to control the colonisation and spread of MRSA. Following on from a previous multi-centre study looking at MRSA colonisation in the nares and throats of a New Zealan...

This research was carried out in order to evaluate the presence and distribution of viral infections causing severe disease eggplant plants collected from different districts Bekaa valley, Lebanon. Most infected showed virus-like symptoms consisting predominantly leaf blotch, mottling chlorotic ring spots; twisting plant dwarf were also observed visited fields. Symptomatic asymptomatic screened...

Adenylate kinase (hereinafter referred to as AK) catalyzes a reversible high-energy phosphoryl transfer reaction between adenine nucleotides. The enzyme contributes to the homeostasis of cellular adenine nucleotide composition in addition to the nucleotide biosynthesis. So far, six AK isozymes, AK1, AK2, AK3, AK4, AK5, and AK6, were identified. AK1 is localized in neuronal processes, sperm tail...

We investigated the mechanisms underlying bradykinin (BK)-induced rise in intracellular Ca++ concentration [Ca++]i and insulin secretion using clonal beta cell line RINm5F. Incubation with a range of concentrations of BK increased in concentration-dependent manners both insulin secretion (BK of 10 nM to 10 microM) and [Ca++]i (BK of 100 nM to 100 microM). In Ca++-containing medium, BK (1 microM...

There is a growing body of evidence to implicate reversible tyrosine phosphorylation as an important mechanism in the control of the adhesive function of cadherins. We previously demonstrated that the receptor protein tyrosine phosphatase PTP m associates with the cadherin–catenin complex in various tissues and cells and, therefore, may be a component of such a regulatory mechanism (Brady-Kalna...

We consider the solution of singular perturbation delay di erential equations (SPDDEs) by using boundary value methods (BVMs). These methods require the solution of some nonsymmetric, large and sparse linear systems. The GMRES method with the Strang-type block-circulant preconditioner is proposed for solving these linear systems. We prove that if an Ak1 ; k2 -stable BVM is used for solving a sy...
