In 310 patients with carotid territory stroke, we investigated whether a history of cardiac disease was more frequent among those with major stroke (n = 169) than among those with minor stroke (n = 141), and whether the two groups differed in values for blood variables directly or indirectly associated with stroke, each variable being adjusted for age and sex. A history of angina pectoris was more
Decreased cerebellar volume is associated with intraventricular hemorrhage (IVH) in very preterm infants and may be a principal component in neurodevelopmental impairment. Cerebellar deposition of blood products from the subarachnoid space has been suggested as a causal mechanism in cerebellar underdevelopment following IVH. Using the preterm rabbit pup IVH model, we evaluated the effects of IVH i
BACKGROUND: Many clinical trials have evaluated the benefit of long-term use of antiplatelet drugs in reducing the risk of clinical thrombotic events. Aspirin and ticlopidine have been shown to be effective, but both have potentially serious adverse effects. Clopidogrel, a new thienopyridine derivative similar to ticlopidine, is an inhibitor of platelet aggregation induced by adenosine diphosphate
Glutathione transferases play an important role in the detoxification of many different endogeneous and exogenous compounds such as metabolites of polycyclic aromatic hydrocarbons (PAH) of cigarette tar. There is evidence that PAH may be atherogenic. The glutathione transferase activity towards trans-stilbene oxide (GST-tSBO) can be separated in blood in GST-positive and GST-negative phenotypes. W
Plasma concentrations of adrenaline, noradrenaline, aldosterone and plasma renin activity were determined in a selected group of 80-year-old men (N = 41) in good health without clinical signs of cardiovascular disease, and were compared to levels in young healthy males (N = 20, 24-28 years). Plasma adrenaline and noradrenaline concentrations were higher (0.24 median; 25th-75th percentiles 0.16-0.3
Eighty-year-old male residents in the community of Malmö were questioned about smoking habits and the occurrence of cardiovascular disease (CVD). Of 1,280 subjects, 122 were selected for further studies and allocated into 4 groups: 1) no CVD, non-smokers; 2) no CVD, smokers; 3) CVD, smokers; and 4) CVD, non-smokers. The smokers had consumed on the average 13 g of tobacco daily for 59 years. Lean b
Background: Although ranibizumab has been used for the treatment of wet age-related macular degeneration (AMD) since 2007, real-world studies still report undertreatment resulting in a less favorable visual outcome. In this study, two different time cohorts of patients treated with ranibizumab for wet AMD in routine care were analyzed to observe whether there was a change over time regarding visua
Glutathione transferases (GST) are detoxifying enzymes who act with many endogenous and exogenous substances such as polycyclic aromatic hydrocarbons (PAH). The GST activity towards trans-stilbene oxide (GST-tSBO) is inherited in an autosomal dominant fashion and can be separated in high (GST-positive) and low (GST-negative) phenotypes when measured in blood. Human fibroblast cultures were establi
Dimethylsulfoxide-soluble particles (DSP) from cigarette smoke and ultraviolet light caused a low degree (cell death less than 30%) and high degree (cell death 60-90%) injury to bovine arterial endothelial cells and smooth muscle cells in culture. Conditioned medium from low degree injured endothelial cells and smooth muscle cells generally inhibited DNA synthesis in new smooth muscle cells or end
The release of prostacyclin by endothelial cells (EC) in culture was studied after exposure to two toxic stimuli (UV light or dimethylsulfoxide-soluble smoke particles (DSP)) or to medium conditioned by smooth muscle cells (SMC), basically or after injury to the SMC. An activity stimulating the release of prostacyclin was found together with growth inhibiting activity from arterial SMC, but dissoc
Polycyclic aromatic hydrocarbons of cigarette smoke have been suggested to be involved in atherogenesis. After being converted to epoxides by monooxidases in the arterial wall the hydrocarbons may exert toxic or mutagenic effects on the smooth muscle cells (SMC). In a previous study we found that dimethylbenzanthracene (DMBA), an inducer of arylhydrocarbonhydroxylase (AHH), increased SMC prolifera
A total of 1280 80-year-old men were invited to a medical examination to study common risk indicators for cardiovascular disease (CVD) in the elderly. From the pool of 811 responders (63.3%), all 122 individuals who fulfilled our inclusion criteria were assigned to one of four groups: (1) no CVD, non-smokers; (2) no CVD, smokers; (3) CVD, smokers; (4) CVD, non-smokers. A telephone interview with 7
A total of 1280 80-year-old men in the community of Malmö were questioned about smoking habits and the occurrence of cardiovascular disease (CVD). After a careful medical and duplex ultrasound examination, four groups were selected for further studies: (1) no CVD, non-smokers: (2) no CVD, smokers: (3) CVD, smokers: (4) CVD, non-smokers. In total 122 individuals participated. The average tobacco co
Glutathione transferase activity towards trans-stilbene oxide (GT-tSBO), an enzyme involved in the detoxification of many substances such as polycyclic aromatic hydrocarbons, was studied in 77 consecutive patients operated with coronary bypass, 73 patients with intermittent claudication, 78 healthy smokers and in 38 healthy non-smokers. The mean ages of these groups were similar. Lack of GT-tSBO w
PURPOSE: To implement an aggregation method in Matlab for generating ActiGraph counts from raw acceleration recorded with an alternative accelerometer device and to investigate the validity of the method. METHODS: The aggregation method including the frequency band-pass filter was implemented and optimized based on standardized sinusoidal acceleration signals generated in Matlab and processed in t
Previous reports have suggested a role for polycyclic aromatic hydrocarbons in the pathogenesis of atherosclerosis. Therefore, the effects of benzpyren (BP) and dimethylbenzanthracene (DMBA) on the arterial smooth muscle cell (SMC) in culture were studied. DMBA increased the proliferation of bovine and rabbit SMC but not of human embryonal fibroblasts or human SMC. BP did not significantly influen
Aims/hypothesis: The aims of this study were to evaluate systematically the predictive power of comprehensive metabolomics profiles in predicting the future risk of type 2 diabetes, and to identify a panel of the most predictive metabolic markers. Methods: We applied an unbiased systems medicine approach to mine metabolite combinations that provide added value in predicting the future incidence of
BACKGROUND Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediatethickness melanomas (1.2 to 3.5 mm). The value of completion lymph-node dissection for patients with sentinel-node metastases is not clear. METHODS In an international trial, we randomly assigned patients with sentine
