The aim of this research was to analyze the effects and the modes of action of elemental sulfur (So) in bioluminescence and respiration of Vibrio fischeri cells and the enzymes crude luciferase, pure catalase, and alcohol dehydrogenase (ADH). Metallic copper removed sulfur and reduced the toxicity of acetone extracts of sediment samples analyzed in the bioluminescence test. The sulfur inhibition o
PURPOSE: The aim of this study was to define the scales and test the validity, reliability, and sensitivity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-H&N35, a questionnaire designed to assess the quality of life of head and neck (H&N) cancer patients in conjunction with the general cancer-specific EORTC QLQ-C30. PATIENTS AND
A case study is presented that evaluates the impact of partial automation strategies on productivity and ergonomics. A company partly automated its assembly and transportation functions while moving from a parallel-batch to a serial line-based production system. Data obtained from company records and key informants were combined with detailed video analysis, biomechanical modelling data and field
The aim of this study was to investigate how overall health, participation in physical activities, self-esteem, and social and financial resources are related to life satisfaction among people aged 65 and older with reduced activities of daily living (ADL) capacity in 6 European countries. A subsample of the European Study of Adults’ Well-Being (ESAW), consisting of 2,195 people with reduced ADL c
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
