Puzzled by recent reports of differences in specific ligand binding to muscle Ca2+ channels, we quantitatively compared the flux of Ca2+ release from the sarcoplasmic reticulum (SR) in skeletal muscle fibers of an amphibian (frog) and a mammal (rat), voltage clamped in a double Vaseline gap chamber. The determinations of release flux were carried out by the(More)
OBJECTIVES To identify factors associated with good and poor recruitment to multicentre trials. DATA SOURCES Part A: database of trials started in or after 1994 and were due to end before 2003 held by the Medical Research Council and Health Technology Assessment Programmes. Part B: interviews with people playing a wide range of roles within four trials(More)
A systematic review was conducted to examine the barriers to, and facilitators of, healthy eating among young people (11-16 years). The review focused on the wider determinants of health, examining community- and society-level interventions. Seven outcome evaluations and eight studies of young people's views were included. The effectiveness of the(More)
In regulating the internal homeostatic environment mammals, by necessity, employ behavioral strategies that differ from the tactics used in coping with contingencies in the external environment. When an animal consumes a meal, the palatability of that meal is automatically adjusted in accordance with the ultimate internal effects of that meal. If the meal(More)
Endometrial carcinoma (EC) is the most common gynecological malignancy in the western world. A widely accepted dualistic model, which has been established on a morphological basis, differentiates EC into two broad categories: Type I oestrogen-dependent adenocarcinoma with an endometrioid morphology and Type II non-oestrogen-dependent EC with a serous(More)
A wealth of indirect data suggest that the H218/AGR16/Edg-5/LP(B2) sphingosine 1-phosphate (S1P) receptor plays important roles in development. In vitro, it activates several forms of development-related signal transduction and regulates cellular proliferation, differentiation and survival. It is expressed during embryogenesis, and mutation of an H218-like(More)
We present a preliminary analysis of 1,771 confirmed cases of influenza A(H1N1)v reported in Peru by 17 July including the frequency of the clinical characteristics, the spatial and age distribution of the cases and the estimate of the transmission potential. Age-specific frequency of cases was highest among school age children and young adults, with the(More)
Human T cells expressing CD161 and an invariant T-cell receptor (TCR) alpha-chain (Valpha24invt T cells) specifically recognize CD1d and appear to have immunoregulatory functions. However, the physiological target cells for this T-cell population, and whether alterations in CD1d expression contribute to the regulation of Valpha24invt T-cell responses,(More)
Randomized controlled trials (RCTs) are widely accepted by the scientific community as the most rigorous way of evaluating interventions in health care. Although their central feature, random allocation of treatment, is generally seen as methodologically appropriate, its application has caused much debate amongst health professionals and ethicists. This(More)
BACKGROUND The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. METHODS Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting(More)
