BACKGROUND Overcommitment (OC) is a pattern of excessive striving. In reaction to work stress, OC has been associated with higher sympathetic nervous system activation and cortisol release, but data on neuroendocrine reactivity to standardized stressors are scarce. We investigated whether OC is associated with differential levels of the stress hormones norepinephrine and cortisol in response to...

Cognitive abilities, such as verbal fluency and mental rotation, are most sensitive to changes in sex steroids but poorly studied in the context of hormonal contraceptive usage. Therefore, we investigated the performance of mental rotation and verbal fluency in young (21.5±1.8 years) healthy oral contraceptive (OC) users (23 women) and non-users (20 women) during the follicular, ovulatory and l...

abstract in order to study the effects of soil texture and temperature on atrazine degradation, an experiment was conducted in completely randomized design with factorial arrangement and 3 replications. experimental factors included, soil texture (sandy loam and silty clay), temperature(10, 20 and 30 oc) and 4 incubation periods(0, 20, 40 and 60 days). soil was spiked with atrazine at a rate of...

abstract soil organic matter and its components are important factors in formation and stability of aggregates and subsequently soil structure. however data regarding organic matter distribution in soil aggregates is scarce, particularly in arid soils of central iran. the objective of this study was to investigate the distribution of organic carbon (oc), total nitrogen (tn), and carbohydrates i...

BACKGROUND: The aim of this study was first, to investigate whether women starting oral contraceptive (OC) use at a young age and before first birth have an increased risk for breast cancer and second, to report difficulties encountered in studying long-term health impacts of medical technologies. METHODS: Breast cancers occurring up until 1997 among 37153 Helsinki students born between 1946 an...

BACKGROUND AND AIMS This prospective trial was designed to compare the performance characteristics of five different screening tests in parallel for the detection of advanced colonic neoplasia: CT colonography (CTC), colonoscopy (OC), flexible sigmoidoscopy (FS), faecal immunochemical stool testing (FIT) and faecal occult blood testing (FOBT). METHODS Average risk adults provided stool specim...

Determination of crop water requirement is one the key parameters for precise irrigation scheduling, especially under limited resources, such as in Egypt. Hence, an accurate estimation reference evapotranspiration (ETo) a vital factor agriculture production, therefore objectives present study were to influence climate change on different seasons and comparing ETo estimations using Blany- Criddl...

BACKGROUND AND OBJECTIVES Fostamatinib is a spleen tyrosine kinase inhibitor that has been investigated as therapy for rheumatoid arthritis and immune thrombocytopenic purpura. The present studies assessed the potential for pharmacokinetic interaction between fostamatinib and the commonly prescribed medications oral contraceptive (OC), warfarin, and statins (rosuvastatin, simvastatin) in health...

Using enrichment procedures, 45 organic solvent-tolerant lipase producer bacterial strains were screened from areas contaminated by oil and organic solvents. Among the strains, 15 isolates exhibited extreme stability toward organic solvents and high lipolytic activity. The NEB-1 isolate which was later identified as Pseudomonas sp. strain NEB-1 by biochemical tests and 16S rDNA gene sequence an...

1. Serum folate level, packed cell volume and haemoglobin concentration of apparently healthy rural Sri Lankan women, between 20 and 45 years and earning up to Rs. 500 (Sri Lankan Rs. 35 u E l Sterling) per month, were estimated during pregnancy and when on oral contraceptive (OC) treatment with Ovulen 50 (ethinyl oestradiol 0.05 mg, ethinodiol diacetate 1 mg). 2. Ovulen 50 administration led t...
