Coronary artery bypass grafting (CABG) remains one of the most common procedures worldwide, and remains the gold standard therapy for symptomatic coronary artery disease (CAD) that involves the left main coronary artery, triple vessel CAD with or without left ventricular dysfunction, and other complex coronary CAD not amenable to percutaneous intervention, especially in diabetic patients or tho...

A 63-year old woman diagnosed in September 2001 with a typical bronchial carcinoid of the left upper lobe bronchus extending into the left main stem bronchus is presented. The patient was unsuitable for standard surgical treatment, and the topography was not amenable for a parenchyma-saving bronchoplastic procedure. Two cycles of bronchoscopic photodynamic therapy (PDT) were undertaken at 6 mon...

in this paper we study the relation between module amenability of θ - lau product a×θb and that of banach algebras a, b. we also discuss module biprojectivity of a×θb. as a consequent we will see that for an inverse semigroup s, l 1 (s) ×θ l 1 (s) is module amenable if and only if s is amenable.

Since 1929 when von Neumann [vN29] introduced the notion of an invariant mean on a group (and more generally on a G-set) there is a permanent interest in the study of the phenomenon known as amenability. Amenable objects like groups, semigroups, algebras, graphs, metric spaces, operator algebras etc. play an important role in different areas of mathematics. A big progress in understanding of th...

In this paper we describe proofs of the pointwise ergodic theorem and Shannon-McMillan-Breiman theorem for discrete amenable groups, along Følner sequences that obey some restrictions. These restrictions are mild enough so that such sequences exist for all amenable groups.

we study topological von neumann regularity and principal von neumann regularity of banach algebras. our main objective is comparing these two types of banach algebras and some other known banach algebras with one another. in particular, we show that the class of topologically von neumann regular banach algebras contains all $c^*$-algebras, group algebras of compact abelian groups and cer...

Let $A$ be a Banach algebra and $E$ be a Banach $A$-bimodule then $S = A oplus E$, the $l^1$-direct sum of $A$ and $E$ becomes a module extension Banach algebra when equipped with the algebras product $(a,x).(a^prime,x^prime)= (aa^prime, a.x^prime+ x.a^prime)$. In this paper, we investigate $triangle$-amenability for these Banach algebras and we show that for discrete inverse semigroup $S$ with...

OBJECTIVE To investigate comparative national trends in mortality from conditions amenable to timely, appropriate medical care and from those considered not to be amenable to such care. DESIGN Analysis of trends in direct age standardised mortality from the 1950s to 1987. SETTING Four eastern European nations (Hungary, Czechoslovakia, Poland, the German Democratic Republic) and two western ...
