Objectives The aim of the present study was to test whether construction workers, who are known to have a relatively higher risk of cardiovascular disease (CVD), had higher concentrations of cortisol in saliva and a lower relative variability when compared with white-collar workers. Methods Data from two groups of male construction workers with physically demanding job assignments, with either reg

A microfabricated proteomic sample preparation and sample presentation device, Integrated Selective Enrichment Target, (ISET), comprising an array of 96 perforated nanovials is described. Each perforated nanovial can be filled with solid-phase extraction media for purification and concentration of peptides prior to matrix-assisted laser desorption/ionization mass spectrometry (MALDI IVIS). The val

Several previous studies have addressed pheromone communication in various flour beetles (Coleoptera: Tenebrionidae), including the confused flour beetle, Tribolium confusum (du Val). Different stereoisomers of 4,8-dimethyldecanal (DMD) were reported as the only components of an aggregation pheromone, but the behavioral activity of DMD is low. In the present study, additional previously reported s

To investigate potential associations between several autoimmune diseases and haematological malignancies, we studied 39,908 cases of leukaemia, Hodgkin's disease, non-Hodgkin's lymphoma and myeloma that occurred during 1987-1999 in Sweden, and 149,344 controls. Hospital discharge diagnoses of psoriasis, Sjogren's syndrome, autoimmune haemolytic anaemia, idiopathic thrombocytopenic purpura, pernic

In order to investigate the ability of the Vitreoscilla hemoglobin (VHb) to act as a peroxidase, the protein was overexpressed in Escerichia coli and purified using a 6xHis-tag. The peroxidase activity of VHb was studied using 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferrocene carboxylic acid (FcCOOH) dopamine and L-dopa as substrates. The effects of external agents such as pH

The aim of the present study was to evaluate the risk for vascular morbidity or death and retinopathy in relation to urinary albumin concentration. To that end, we performed a 5-year follow-up study of all type 2 diabetic patients attending the outpatient-clinic. A total of 444 (98.4%) out of 451 adult patients initially studied were evaluated for the degree of retinopathy and levels of HbA1c bloo

Objectives To evaluate the association of socioeconomic position with adenocarcinoma of the oesophagus and stomach. Methods The European Prospective Investigation into Cancer and Nutrition (EPIC) cohort comprises about 520000 participants mostly aged 35-70 years. Information on diet and lifestyle was collected at recruitment. After an average follow-up of 6.5 years, 268 cases with adenocarcinoma o

Maximal utility of accessible data is attractive to all partners in clinical research, whether it directly improves patient care or more accurately allows identification of the safety and efficacy of a new drug or procedure. The Food and Drug Administration (FDA) has presented a guideline draft addressing digitization of electrocardiogram (ECG) data in clinical trials to improve the standards for

The influence of gender, age, residential area, and socioeconomic status on the blood and serum levels of 13 trace elements was studied in boys and girls living in two Swedish cities with different socioeconomic and environmental characters. The same groups of adolescents were sampled twice, at ages 15 (n = 372) and 17 (n = 294) years. All the investigated factors were shown to be of importance. A

OBJECTIVE: To see if there is a relationship between clinical and laboratory tests of balance, muscular strength and gait in elderly women. DESIGN: A randomized population-based study. SETTINGS: Malmo, Sweden. METHODS: We investigated balance with a simple test of standing on one leg, as well as a computerized balance platform. Muscular strength was tested by computerized dynamometer. Extension an

We report here on a procedure to obtain large amounts of a chloroplast-localized heat shock protein (HSP21) with unknown structure and function, by using anEscherichia coliexpression system for the pea (Pisum sativum) protein and a purification procedure based on perfusion ion-exchange chromatography. After initial precipitation steps, the sample was applied to cation- and anion-exchange on two co

The effects of heavy-metal-containing sewage sludge on the soil microbial community were studied in two agricultural soils of different textures, which had been contaminated separately with three predominantly single metals (Cu, Zn, and Ni) at two different levels more than 20 years ago. We compared three community-based microbiological measurements, namely, phospholipid fatty acid (PLFA) analysis

In recent years, the renewed presence of religion in the European societies has inspired a number of intellectuals on a popular as well as academic level to critically engage with religion. The aim of this article is to give a contribution to this debate. In contrast to the rather reductive and objectifying accounts of religion offered in much of the contemporary critique, I argue that a relevant

For a concrete beam resting on a bed of sand, an analytical solution technique is derived by which the mobility can be identified. To achieve realistic predictions, significant damping in the bed needs to be introduced. The modest damping of the concrete has little effect on the mobility for small frequencies whereas it has a significant effect for higher frequencies. An imperfection in the bed in
