BACKGROUND Mild hyperhomocysteinaemia is a cardiovascular risk factor in patients with type 2 diabetes mellitus. Homocysteine may exert its detrimental effects through induction of endothelial dysfunction and/or chronic inflammation. In this study, we examined the effects of homocysteine-lowering therapy with folic acid on biochemical markers of endothelial dysfunction and low-grade inflammatio...

The Australian Government intends to mandate filtering at the Internet Service Provider (ISP) level to provide a “clean feed” to all subscribers. It claims the current arrangement that includes optional filtering at the Personal Computer (PC) level has failed to protect children from unsuitable Internet content. This paper addresses three key questions that are relevant to IT professionals ever...

The initiation of protein synthesis by Streptococcus faecalis R grown in folate-free culture occurs without N-formylation or N-acylation of methionyl-tRNA(f) (Met). Methionyl-tRNA synthetase and methionyl-tRNA formyltransferase were partially purified from S. faecalis grown under normal culture conditions in the presence of folate (plus-folate); the general properties of the enzymes were determ...

Let H+n(R) be the cone of all positive semidefinite n x real matrices. Two best known partial orders that were mostly studied on subsets square complex matrices are L?wner and minus orders. Motivated by applications in statistics we study these H+ (R). We describe form surjective maps (R), > 1, preserve order both directions. present an equivalent definition (R) also characterize surjective,...

Fluxes of ions and water across the short-circuited, excised bullfrog lung were determined by radioisotope techniques. The unidirectional flows of Na+, K+, Ca++, TcO4 minus, HCO3 minus, gluconate, rho-aminohippurate, dinitrophenolate, SO4 equal to, and water were symmetrical. Both HCO3 minus fluxes were reduced by acetazolamide. In contrast, Cl minus, Br minus I minus, and SCN minus movement fr...

A function f : V (G) → {−1, 0, 1} is a minus dominating function if for every vertex v ∈ V (G), ∑ u∈N [v] f(u) ≥ 1. A minus dominating function f of G is called a global minus dominating function if f is also a minus dominating function of the complement G of G. The global minus domination number γ− g (G) of G is defined as γ − g (G) = min{ ∑ v∈V (G) f(v) | f is a global minus dominating functi...

Let K be an imaginary quadratic field where p splits. We study signed Selmer groups for non-ordinary modular forms over the anticyclotomic ℤ -extension of K, showing that one inclusion Iwasawa main conjecture involving p-adic L-function Bertolini–Darmon–Prasanna implies their μ-invariants vanish. This gives alternative method to reprove a recent result Matar on vanishing plus and minus elliptic...
