Paediatric flexible bronchoscopy (F.B.) with bronchoalveolar lavage (B.A.L.) is an increasingly important investigation. Retrospective review of 180 FB performed over a 5 year period by a single operator was undertaken. Common indications included recurrent lower respiratory tract infections (n = 92, 51%), persistent atelectasis (n = 43, 24%), persistent infiltrates (n = 18, 10%) and persistent...

The aim of this study is to determine miR-22 expression levels in peripheral blood mononuclear cells (PBMCs) of patients with coronary artery disease (CAD) and to investigate whether MCP-1 expression is regulated by miR-22. miR-22 expression in PBMCs from 60 CAD patients including stable angina pectoris (SAP) (n = 29), unstable angina pectoris (UAP) or non-ST elevation myocardial infarction (NS...

A well-constituted plant or animal cell is most certainly equipped with a functional, regulated organization of its impressive array of molecules, and there is no reason to suppose that the coenocytic hypha of a watermold is constructed differently from the cells of other eukaryotes in this regard. Unfortunately, there is a vexatious shortcoming to the collection of facts surrounding the biolog...

The primal-dual method increases the dual variables gradually until some dual constraint becomes tight. Then, the primal variable corresponding to the tight dual constraint is ‘bought’ (or selected), and the process continues till we get a feasible primal solution. Next, we compare the value of the primal solution to the value of the dual solution to get an appropriate approximation factor (or ...

Consider a 3-uniform hypergraph of order n with clique number k such that the intersection all its k-cliques is empty. Szemerédi and Petruska proved n?8m2+3m, for fixed m=n?k, they conjectured sharp bound n?(m+22). This problem known to be equivalent determining maximum ?-critical transversal m (details may also found in companion paper by Kézdy Lehel). The best bound, n?34m2+m+1, was obtained ...
