Five viruses, unrelated to bovine ephemeral fever virus (BEFV), were isolated from Culicoides biting-midges collected during the summer months of the years 1968-69 and 1969-70 near a cattle herd in which cases of BEF occurred and at an open horse stable at Onderstepoort. These viruses were investigated by means of serological, electron-microscopical and physicochemical tests. It was established...

AIMS The chemokine stromal cell-derived factor-1 (SDF-1) and its receptor (CXCR4, CXC chemokine receptor 4) play a critical role in the process of post-natal neovascularization. Here, we investigated the role of CXCR4(+) bone marrow cells (BMCs) in neovascularization in a murine hindlimb ischaemia model. METHODS AND RESULTS We found that the expression of CXCR4 in BMCs was specifically upregu...

BACKGROUND The initiation of a cleavage furrow is essential to separate cells during cytokinesis, but little is known about the mechanisms controlling this actin-driven process. Previous studies in C. elegans embryos revealed that inactivation of the CUL-3-based E3 ligase activator rfl-1 results in an aberrant microtubule network, ectopic furrowing during pronuclear migration, and defects durin...

UNLABELLED The aim of this study was to compare, prospectively, traditional pervaginal cul-de-sac aspiration cytology with an ultrasonographic-guided aspirate in the detection of residual or recurrent ovarian carcinoma. PATIENTS AND METHODS Fifty-one patients with ovarian carcinoma were monitored during chemotherapy (21 patients) or follow-up (30 patients) after first-line treatment. All pati...

[CuX(/i-pydz)] 1 3 (X = Cl, Br, I; pydz = pyrid­ azine) may be prepared by self-assembly in acetonitrile solution at 120 °C (1) or room temper­ ature (2, 3). Individual chains contain (CuX)2 rings and dimeric [Cu(^-pydz) ] 2 substr...

Background: The SYNergy between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery (SYNTAX) score is a scoring system that helps to decide on surgery or percutaneous coronary intervention (PCI) in patients acute myocardial infarction (MI), studies are showing the prognostic value of this both AMI artery disease undergoing PCI. In syndrome (ACS) patients, infarct-related complexit...

Oxovanadium(IV), manganese(II) and copper(II) complexes of a Schiff base ligand derived from 2,4-dihydroxyacetophenone and 1,2-diaminocyclohexane have been encapsulated in the nanocavity of zeolite-Y by flexible ligand method and characterized by metal analysis, IR spectroscopic studies and X-ray diffraction patterns. The encapsulated complexes abbreviated here as CuL-Y, MnL-Y and VOL-Y catalyz...

A major adaptive pathway for hypoxia is hypoxic preconditioning (HPC), a form of endogenous protection that renders cells tolerant to severe challenges of hypoxia. We sought to define the antiinflammatory properties of HPC. cDNA microarray analysis of lung tissue from mice subjected to hypoxia or HPC identified a cluster of NF-kappaB-regulated genes whose expression is attenuated by HPC.
