Role of p190RhoGAP in beta(2) integrin regulation of RhoA in human neutrophils

We found that engagement of beta (2) integrins on human neutrophils induced activation of RhoA, as indicated by the increased ratio of GTP:GTP + GDP recovered on RhoA and translocation of RhoA to a membrane fraction. The clustering of beta (2) integrins also induced a time-dependent increase in GDP bound to RhoA, which correlated with beta (2) integrin-induced activation of p190RhoGAP. The activat

Oil-continuous microemulsions mixed with an amphiphilic graft copolymer or with the parent homopolymer - Polymer-droplet interactions as revealed by phase behavior

Polymer-droplet interactions have been Studied in AOT/water/isooctane oil-continuous microemulsions mixed with an amphiphilic graft copolymer. or with the parent homopolymer (AOT = sodium bis(2-ethylhexyl) sulfosuccinate). The graft copolymer has an oil-soluble poly(dodecyl methacrylate) backbone and water-soluble poly(ethylene glycol) side chains. Pseudo-ternary polymer/droplet/isooctane phase di

Hepatitis C virus transmission, 1988-1991, via blood components from donors subsequently found to be anti-HCV-positive

The recipients of blood components, from the first 12 anti-hepatitis C virus (HCV) positive donors identified by blood donor screening, 1985-1991, were traced retrospectively and tested to assess the HCV transmission rate, HCV genotypes and disease severity. Three enzyme-linked immunosorbent assay (ELISA) positive but RIBA-indeterminate and HCV RNA-negative donors did not transmit HCV to their 9 t

Prognostic potential of flow cytometric S-phase and ploidy prospectively determined in primary breast carcinomas

In a prospective study of a consecutive breast cancer series accumulated in the period 1978-82, the S-phase fraction (SPF) and ploidy status were determined by flow cytometry performed on cell nuclei derived from samples of 580 primary tumors. Sixty percent of the tumors were non-diploid. After correction for debris the median SPF values were 7.3% overall, 12% for non-diploid tumors, and 2.9% for

Precision lifetime measurement of the 2p P-2(3/2) level for Li-like Ni by beam-foil spectroscopy

In this paper we present a precise and reliable measurement of the 1s(2)2p P-2(3/2) lifetime for Li-like Ni. The measurement was done using the technique of beam-foil spectroscopy employing a beam of 5.9 MeV/u Ni from the UNILAC accelerator at GSI. Special attention was taken concerning satellite blending and foil-ageing problems to justify the reliability of the lifetime value extracted from the

The use of national health registers for studying environmental causes of congenital defects

This review summarizes and discusses the use of central health registers in studies of causes of congenital malformations. The review is illustrated using data from the Swedish Medical Birth Register with adjacent registers and gives examples of different methods to identify environmental exposures. The review stresses the usefulness of this approach but also the inherent problems of which the res

Older people's views of prioritisation and resource allocation in health care

Popular Abstract in Swedish Prioriteringar av olika slag har alltid genomförts inom hälso- och sjukvård, vilket har inneburit att vissa verksamheter och patienter har prioriterats och andra har valts bort. Tidigare studier som har varit fokuserade på allmänhetens syn på vem eller vilka som ska prioriteras, har framförallt varit riktade till yngre och medelålders personer. I dessa studier framkommeThe aim of this thesis was to investigate older people's views and experience of prioritisation and resource allocation in health care, which is important because older people are the group that use public health care and service most. The aim was also to investigate differences in the view of prioritisation and resource allocation in relation to age, gender, housing, health-related quality of lif

Pearl and Contemplative Writing

This dissertation places Pearl in the context of works by the English fourteenth-century contemplative writers (‘mystics’), as well as of patristic and other theological treatises, focusing on the theme of comprehending and speaking about a transcendent divine dimension. The purpose is to show that Pearl and the works of Julian of Norwich, Margery Kempe, Walter Hilton, Richard Rolle and the author

Enhancing material and biological properties of calcium phosphate bone substitute

Calcium phosphate materials (CaPs) have proven biocompatible and useful in clinical situations. One CaP showing promise in the clinic is alpha phase tricalcium phosphate ([alpha]-TCP). [alpha]-TCP in powder form can be hydrated and undergoes a reaction resulting in calcium deficient hydroxyapatite (CDHA). The similarity of CDHA and human bone makes [alpha]-TCP a very viable material for applicatio
