Metabolism of estrone sulfate by normal breast tissue : Influence of menopausal status and oral contraceptives

The metabolism of [ 3 H]estrone sulfate ([ 3 H]E 1 S) was studied in normal breast tissue from 10 premenopausal women without oral contraceptives (OC), in 12 OC users and in 9 untreated postmenopausal women. [ 3 H]E 1 S was converted into estrone ([ 3 H]E 1 ) and estradiol-17β ([ 3 H]E 2 ) by tissue samples from all three groups of women, with only minor formation of other unconjugated compounds.

papiNet - A vehicle for supply chain standardization and integratior

The Paper and Plastics Education and Research Insitute at the University of North Florida and NPTA have taken an initiative to adopt and implement the papiNet standards for supply chain standardization and integration. papiNet can be described as a global standard for the paper and forest industries. The companies, which want to adopt papiNet, are required to follow the standards developed by the

Interesterification of phosphatidylcholine with lipases in organic media

Lipases were investigated with respect to their ability to catalyse the incorporation of fatty acids into phosphatidylcholine (PC) by interesterification reactions. The enzymes were dried onto solid support materials and the conversions were carried out in water-saturated toluene. Three lipases (two fungal and one plant enzyme) had the desired activity; immobilized lipase from Mucor miehei (Lipozy

Optimization of galactooligosaccharide production from lactose using β-glycosidases from hyperthermophiles

The maximal production of galactooligosaccharides (GOS) from lactose by (β-glycosidases from the hyperthermophilic archaea, Sulfolobus solfataricus (LacS) (derived from lacS gene) and Pyrococcus furiosus (CelB) (derived from celB gene) was optimized. The performance of these enzymes under extreme reaction conditions, temperatures up to 95°C and lactose concentrations up to 90% (w/v), were studied.

Does the bile salt stimulated lipase of human milk have a role in the use of the milk long-chain polyunsaturated fatty acids?

Long-chain polyunsaturated (LCP) fatty acids derived from linoleic (18:2 n-6) and alpha-linolenic (18:3 n-3) acids are considered essential nutrients in preterm infants. The efficiency by which such fatty acids are released as absorbable products from triacylglycerol was explored in vitro using rat chylomicron triacylglycerol as substrate. When incubated with purified human pancreatic colipase-depLong-chain polyunsaturated (LCP) fatty acids derived from linoleic (18:2 n-6) and alpha-linolenic (18:3 n-3) acids are considered essential nutrients in preterm infants.

Drell-Yan, ZZ, W+W- production in SM & ADD model to NLO+PS accuracy at the LHC

In this paper, we present the next-to-leading order QCD corrections for di-lepton, di-electroweak boson (ZZ, W+W-) production in both the SM and the ADD model, matched to the HERWIG parton shower using the aMC@NLO framework. A selection of results at the 8 TeV LHC, which exhibit deviations from the SM as a result of the large extra-dimension scenario, are presented.

Prognostic implications of cytogenetic findings in kidney cancer

Objective. To evaluate the prognostic impact of cytogenetic findings in renal cell carcinoma (RCC). Patients and methods. Tumour cytogenetics, histomorphology, DNA ploidy and S-phase fraction, stage, size, and grade were related to survival in 50 consecutive patients with RCC. The mean follow-up was 3.9 years (median 4.2. range 0-8.8). Results. The predictive probability for recurrence-free surviv

Strukturell hjärnavbildning kan förbättra diagnostiken vid demens

New guidelines on care in dementia from the Swedish National Board of Health and Welfare emphasize that brain imaging should be included in the standard diagnostic evaluation. Evidence supports the importance of regional/global atrophy and white matter changes in dementia. However, the use of imaging in dementia evaluation is often sub-optimal, urging optimization of clinical imaging practice. Ima

Within-Host Adaptation Mediated by Intergenic Evolution in Pseudomonas aeruginosa

Bacterial pathogens evolve during the course of infection as they adapt to the selective pressures that confront them inside the host. Identification of adaptive mutations and their contributions to pathogen fitness remains a central challenge. Although mutations can either target intergenic or coding regions in the pathogen genome, studies of host adaptation have focused predominantly on molecula

A prospective study of orthostatic blood pressure in diabetic patients

To clarify whether orthostatic blood pressure is affected by the type of diabetes, cardiac autonomic neuropathy, and the duration of diabetes, orthostatic blood pressure (passive 90°tilt) was evaluated in 102 patients with insulin dependent diabetes mellitus (IDDM), 51 patients with non-insulin dependent diabetes mellitus (NIDDM), and in 238 control subjects in a first study followed up after 8 to

Bias in diet assessment methods - Consequences of collinearity and measurement errors on power and observed relative risks

Background. If several risk factors for disease are considered in a regression model and these factors are affected by measurement errors, the observed relative risk will be attenuated. In nutritional epidemiology, several nutrient variables show strong correlation, described as collinearity. The observed relative risk will then depend not only on the validity of the chosen diet assessment method

Malnutrition in geriatric patients : A neglected problem?

The nutrient intake in geriatric long-stay patients and the mortality risk associated with low energy intake were studied in 61 patients, 43 women and 18 men, with a mean age of 87 years, at a geriatric long-stay care hospital during a 6-month follow-up. Dietary intake was assessed with a 9-day dietary record. Energy expenditure was calculated assuming a physical activity level of 1.33 × basal met
