Randomised controlled trial of a mobile phone infant resuscitation guide.

Aim: The aim of this study was to develop a mobile phone resuscitation guide (MPRG) and to evaluate its use during simulated resuscitation of a mannequin.

Methods: An MPRG was developed using EpiSurveyor. A randomised controlled trial was performed in school-going children aged 15-16 years.

TGF-beta1-Induced MAPK activation promotes collagen synthesis, nodule formation, redox stress and cellular senescence in porcine aortic valve interstitial cells.

Background And Aim Of The Study: Aortic valve stenosis is a major cause of valve replacement, particularly in the elderly. TGF-beta1 is upregulated in stenotic valves and induces calcification and collagen synthesis in cultured valve interstitial cells. It has been shown previously that TGF-beta1 increases reactive oxygen species (ROS) in these cells in association with calcifying nodule formation, but the cellular signaling pathways responsible for these TGF-beta1-induced effects are not well defined.

Three decades of quality improvement in electroconvulsive therapy: exploring the role of accreditation.

Objectives: This study aims to track electroconvulsive therapy (ECT) clinics' compliance with standards for the administration of ECT before and after the introduction of the Electroconvulsive Therapy Accreditation Service (ECTAS) in 2003.

Methods: Three audits on the practice of ECT were retrospectively analyzed, and ECTAS data from 2004 to 2011 were prospectively analyzed. Overall compliance with 10 ECT audit standards was presented in 2 ways: annually and for each of the 3 waves of accreditation.

Inhibition of calcifying nodule formation in cultured porcine aortic valve cells by nitric oxide donors.

Calcific aortic stenosis displays some similarities to atherosclerosis including evidence of endothelial dysfunction. Whether nitric oxide (NO), which is produced by valvular endothelium, has direct protective effects extending to calcification processes in aortic valve cells has not previously been examined. In vitro calcifying nodules in porcine aortic valve interstitial cell cultures, formed in response to transforming growth factor-beta1 (TGF-beta1) 5 ng/ml, were inhibited by NO donors DETA-NONOate 5-100 microM, and sodium nitroprusside (SNP) 3 microM.

Effect of the anti-anginal agent, perhexiline, on neutrophil, valvular and vascular superoxide formation.

The prophylactic anti-anginal agent, perhexiline, may also be effective in acute coronary syndromes and advanced aortic valvular stenosis, conditions associated with enhanced inflammation. Its potential effects on superoxide formation via NADPH oxidase were measured by lucigenin-mediated chemiluminescence. Perhexiline inhibited superoxide formation in intact neutrophils stimulated with formyl Met Leu Phe (fMLP) 4 muM or with phorbol myristate acetate (PMA) 162 nM - IC50 2.

Dissociation between metabolic and efficiency effects of perhexiline in normoxic rat myocardium.

The antianginal agent perhexiline inhibits rat cardiac carnitine palmitoyltransferase-1 (CPT-1) and CPT-2, key enzymes for mitochondrial transport of long-chain fatty acids. We tested the hypothesis that perhexiline, in therapeutic concentrations (2 microM), inhibits palmitate oxidation and enhances glucose oxidation in isolated rat cardiomyocytes and in the working rat heart, thereby increasing efficiency of oxygen utilization. In isolated cardiomyocytes, perhexiline (2 microM) exerted no acute effects on palmitate oxidation, but after 48 hours pre-exposure oxidation was inhibited by perhexiline (2 to 10 microM) by 15% to 35% (P < 0.

Differential production of adrenal steroids by purified cells of the human adrenal cortex is relative rather than absolute.

Objectives: The adrenal cortex produces aldosterone, cortisol and androgens in response to ACTH and angiotensin II. To define the differential response of morphologically distinct cells of the adrenal cortex, we examined the phenotypical and functional characteristics of human adrenocortical cells.

Results: Tumour growth factor-beta receptor-1 (TGFbeta-R1) and CYP-11 were found to be expressed predominantly in the zona fasciculata, whereas human leukocyte antigen (HLA-DR) and CYP-17 were localised to the zona reticularis.
