Background: Between smokers matched for daily tobacco consumption there are marked variations of the cardiovascular risk. This follow up of the population based cohort “Men born in 1914” from Malmö, Sweden, explored whether this is accounted for by the levels of carbon monoxide (CO). Methods: Three hundred and sixty-five men without history of cardiovascular disease (CVD) were followed over 27

The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity). Estimation of hydraulic conductivity in vivo with the CFC method has therefore been performed under conditions of unchanged vascular tone and metabolic influence. There are studies, however, that did n

Objective: To evaluate how often low 5-min Apgar scores (AS(5-min)) at term are associated with asphyxia. Study design: A cohort- and case-control study, including all 183 term infants with AS(5-min) below 7 born at Lund University Hospital during 1993-2002, antepartum deaths excluded. The control group included 183 randomly selected term newborns with AS(5-min) 9-10. Cardiotocography (CTG) traces

A key unanswered question in smooth muscle biology is whether phosphorylation of the myosin regulatory light chain (RLC) is sufficient for regulation of contraction, or if thin-filament-based regulatory systems also contribute to this process. To address this issue, the endogenous RLC was extracted from single smooth muscle cells and replaced with either a thiophosphorylated RLC or a mutant RLC (T

Skeletal muscle trauma and myocardial infarction both increase the serum values of the creatine kinase isoenzyme MB (CK-MB) which may render the diagnosis of perioperative myocardial infarction in major orthopaedic surgery more difficult. The significance of postoperative changes in CK-MB was studied in 30 patients subjected to total hip replacement (THR), and the results were compared to CK-MB in

Defensins represent an evolutionarily conserved group of small peptides with potent antibacterial activities. We report here that extracellular proteinases secreted by the human pathogens Pseudomonas aeruginosa, Enterococcus faecalis and Streptococcus pyogenes release dermatan sulphate by degrading dermatan sulphate-containing proteoglycans, such as decorin. Dermatan sulphate was found to bind to

In the present study, we have investigated whether changes in vascular reactivity in congestive heart failure (CHF) patients can be detected in the cutaneous microvessels and whether these changes are due to endothelial dysfunction, are affected by increasing age and related to an ongoing inflammation. The responses to local warming and iontophoretically administered endothelium-dependent and -ind

BACKGROUND: Cardiac surgery places extensive stress on spouses who often are more worried than the patients themselves. Spouses can experience difficult and demanding situations when the partner becomes critically ill. OBJECTIVES: To identify, describe, and conceptualize the individual needs of spouses of patients with complications of heart failure after cardiac surgery. METHODS: Grounded theory

Studies on 3,4-methylenedioxymethamphetamine ("ecstasy")-induced neurotoxicity mainly focus on damage of serotonergic terminals. Less attention has been given to neuronal cell death produced by 3,4-methylenedioxymethamphetamine and other amphetamines in areas including the cortex, striatum and thalamus. In the present study we investigated 3,4-methylenedioxymethamphetamine-induced neurotoxicity in

This study investigated the profile of long-term blood pressure (BP)-lowering medication in a population-based cohort, and whether treatment effects on BP control or risk of cardiovascular disease (CVD) differed between the types or patterns of BP-lowering regimes. In treated hypertensive patients, only 11.3% had a BP < 140/90 mm Hg. Inadequate drug combination and underestimation of global risk s

Human myxoid liposarcoma contains a characteristic t(12;16) chromosomal translocation that results in fusion of the N-terminal domain of the translocated in liposarcoma (TLS) protein to the C/EBP homologous protein (CHOP). TLS possesses structural motifs that suggest it may participate in RNA processing. We demonstrate that in human myxoid liposarcoma cells, wild-type TLS binds to RNA polymerase I

The amyloid-beta precursor protein (APP) and its pathogenic byproduct beta-amyloid peptide (Abeta) play central roles in the pathogenesis of Alzheimer's disease (AD). Reduction in levels of the potentially toxic Abeta is one of the most important therapeutic goals in AD. Recent studies have shown that bivalent metals such as iron, copper, and zinc are involved in APP expression, Abeta deposition,
