This paper reports a method to produce a solvent-free extract from green tea leaves with high content of catechins and low content of caffeine, in two steps and using only "green" solvents. The method is based on the pressurized liquid extraction (PLE) of the green tea leaves using ethyl lactate as solvent, followed by a selective precipitation procedure using the supercritical carbon dioxide (SCC

Given the anthropometric differences between men and women and previous evidence of sex-difference in genetic effects, we conducted a genome-wide search for sexually dimorphic associations with height, weight, body mass index, waist circumference, hip circumference, and waist-to-hip-ratio (133,723 individuals) and took forward 348 SNPs into follow-up (additional 137,052 individuals) in a total of

Numerical properties of the smooth particle mesh Ewald (SPME) sum [U. Essmann, L. Perera, M. L. Berkowitz, T. Darden, H. Lee, and L. G. Pedersen, J. Chem. Phys. 103, 8577 (1995)] have been investigated by molecular dynamics simulation of ionic solutions and dipolar fluids. Scaling dependence of execution time on the number of particles at optimal performance have been determined and compared with

Purpose. Patients with soft tissue sarcomas (STS) are at increased risk of second primary malignancies, including a second STS, but distinction between metastases and a second primary STS is difficult. Patients and Methods. Array-based comparative genomic hybridization (aCGH) was applied to 30 multiple STS of the extremities and the trunk wall from 13 patients. Different histotypes were present wi

A new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. Today this level is about 80%. The growing car disassembly industry was chosen as the study object of this thesis. Due to the increased demands on recycling, the disassembly industry is expected to undergo comprehensive

The pioneer microbiota of the neonate may affect future actions of the immune system. This study aimed to map the pioneer microbiota in healthy neonates vaginally born at term. A subgroup of neonates born large for gestational age (LGA) was compared with the neonates appropriate for gestational age (AGA). Fecal samples were collected, within 48 hours after birth, from 79 neonates. Quantitative pol

Total antioxidant capacity (TAC), total phenolic compounds (TPH), total flavonoids (TF) and the amounts of individual phenolic compounds were assessed in Bolivian potato cultivars (various Solanum species) before, during and after the traditional freezing and sun-drying of potatoes known as chunos. The TAC of chunos ranged from 0.4 to 2.7 mu mol Trolox equivalents/g dry matter using 2,2'-azino-bis

Speed and accuracy are crucial prerequisites in the application of proteomic methods to clinical medicine. We describe a microfluidic-based nanovial array for rapid proteolytic processing linked to MALDI-TOF MS. This microscale format consumes only minute amounts of sample, and it is compatible with rapid bioanalytical protocols and high-sensitivity readouts. Arrays of vials (300 mu m in diameter

A new, cyclodextrin glycosyltransferase (CGTase) from an alkaliphilic B. agaradhaerens strain LS-3C, isolated front an Ethiopian soda lake. was purified up to 43-fold by starch adsorption with a yield of 50%. The enzyme was a monomer with an estimated molecular weight of 110 kDa, representing the largest Bacillus CGTase reported so far. The isoelectric point (pI) of the enzyme was 6.9. The CGTase

OBJECTIVE: To measure intracellular and tissue pH in periarticular soft tissue during different phases of antigen induced arthritis in the rat. METHODS: pH was calculated using the following values: (1) the distribution of [14C]-dimethyl-oxazolidinedione; (2) the total tissue water and the extracellular space water volume, which was measured as [14C]-sucrose distribution in nephrectomized rats. Ex

Parasol is a computer program for calculating the solar and thermal properties of windows with sunshades and the energy demands of a room with a window/shading system. The program has three main features. One of them is a calculation of g, T and U for normal incidence of beam irradiation, which is performed as soon as a window or an internal/interpane sunshade is selected. The other two are based

Popular Abstract in Swedish I Sverige har andelen förtidspensionärer ökat under lång tid och uppgick år 1998 till 7.6% av befolkningen i arbetsför ålder (16-64 år). Den vanligaste orsaken till att en individ förtidspensioneras är reducerad arbetsförmåga till följd av problem i rörelseorganen. Kunskaperna om förtidspensionärers livskvalitet är bristfälliga. Syftet med denna studie var att studera lThe starting-point of this thesis was the high rate of disability pensioners in Sweden and the lack of knowledge about what a disability pension entails for quality of life (QL). The aim of the study was to gain knowledge about QL among disability retirees with musculoskeletal disorders (ERPs). A questionnaire was sent in 1992 to 450 ERPs in Kristianstad Municipality, Sweden, granted their disabil

The adsorption of methylene blue (MB) onto zirconium phosphate (ZrP) was studied and the adsorption capacity value and isotherms were determined. The adsorption capacity of ZrP was increased after being exposed to gas phase n-butyl amine. The adsorbed MB on ZrP was used as a modifier material in carbon paste electrode (MCPE), which in turn was used in voltammetric investigations and flow injection

In this study we investigated if smoking subjects with a normal or slightly decreased lung function differ in the lymphocyte pattern compared to never-smokers. In a group of 'healthy' smokers (n = 58) and never-smokers (n = 34) 60 years old, we investigated the lymphocyte pattern in both BAL (n = 30 and n = 18 respectively), bronchial epithelium and lamina propria (n = 14 and n = 10 respectively)

The long-lived, light-induced radical Y-D(.) of the Tyr161 residue in the D2 protein of Photosystem 11 (PSII) is known to magnetically interact with the CaMn4 cluster, situated similar to 30 angstrom away. In this study we report a transient step-change increase in YD EPR intensity upon the application of a single laser flash to S, state-synchronised PSII-enriched membranes from spinach. This tran

Background: Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a social and not a biologic construct.Methods: We developed new eGFR equations without race using data from two development data sets: 10 studies (8254 participants, 31.5% Black) for serum c

This study investigated the tolerance and safety of pasteurized donor human milk (PDHM) given either alone or together with commercially-used supplements in a porcine model of premature infants. A porcine model, mimicking human neonates at 30-32 weeks of gestational age, was used. The 7-day experiment was performed on 20 piglets. After birth, the piglets were infused with porcine immunoglobulins v

Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all f

Reduced chemical kinetic mechanisms are essential for atmospheric chemistry modeling where the use of explicit kinetic schemes is too computationally demanding. By tailoring mechanisms to specific cases, the size of the mechanism can be kept small, without significant loss of accuracy in predictions of selected species’ concentrations. In the present work, we present small kinetic mechanisms tailo
