Coffee and tea contain numerous antimutagenic and antioxidant components and high levels of caffeine that may protect against colorectal cancer (CRC). We investigated the association between coffee and tea consumption and CRC risk and studied potential effect modification by CYP1A2 and NAT2 genotypes, enzymes involved in the metabolization of caffeine. Data from 477,071 participants (70.2% female)

This study examined how differences in visuo-perceptual patterns are related to psychopathology. Fifty-six patients (37 women, 19 men; M age = 43.8 yr., SD = 13.4) with a main diagnosis of unipolar depression and 42 patients (22 women, 20 men; M age = 42.0 yr., SD = 11.1) with a main diagnosis of somatoform disorder were compared. The duration and trend of a visual motion aftereffect were measured

To distinguish between natural and anthropogenic forcing, the supposedly ongoing global warming needs to be put in a longer, geological perspective. When the last ca. 20 000 yr of climate development is reviewed, including the climatically dramatic period when the Last Ice Age ended, the Last Termination, it appears that the last centuries of globally rising temperatures should be regarded as an a

Background: Dementia with Lewy bodies (DLB) accounts for 15-20%, of the millions of people worldwide with dementia. Accurate diagnosis is essential to avoid harm and optimize clinical management. There is therefore an urgent need to identify reliable biomarkers. Methods: Mass spectrometry was used to determine the specificity of antibody alpha-synuclein (211) for alpha-synuclein. Using gel electro

Six-membered cyclic carbonates are potential monomers for phosgene and/or isocyanate free polycarbonates and polyurethanes via ring-opening polymerization. A two-step process for their synthesis comprising lipase-catalyzed transesterificationofa polyol, trimethylolpropane(TMP) with dimethylcarbonate(DMC)in a solvent-free system followed by thermal cyclization was optimized to improve process effic

A modification of the Roe scheme called L2Roe for low dissipation low Mach Roe is presented. It reduces the dissipation of kinetic energy at the highest resolved wave numbers in a low Mach number test case of decaying isotropic turbulence. This is achieved by scaling the jumps in all discrete velocity components within the numerical flux function. An asymptotic analysis is used to show the correct

We start with two puzzles: first, how to explain the European Union (EU)'s decline as a climate change leader at the Copenhagen summit? Second, how to understand the partial revival of its leadership position at the Durban climate summit? We advance a twofold explanation, focusing on changes in relative power relations among major powers but also on negotiation strategies and coalition building. I

PURPOSE: Body mass index (BMI), waist-to-hip ratio (WHR), and tumor characteristics affect disease-free survival. Larger breast size may increase breast cancer risk, but its influence on disease-free survival is unclear. The purpose of this study was to elucidate whether breast size independently influenced disease-free survival in breast cancer patients. METHODS: Body measurements were obtain

Rare-variant association studies in common, complex diseases are customarily conducted under an additive risk model in both single-variant and burden testing. Here, we describe a method to improve detection of rare recessive variants in complex diseases termed RAFT (recessive-allele-frequency-based test). We found that RAFT outperforms existing approaches when the variant influences disease risk i

A method based on hollow-fibre liquid phase microextraction combined with gas chromatography was developed for determination of specific bile acids in caecal materials of rats. Nine unconjugated bile acids, including the primary bile acids (cholic acid, chenodeoxycholic acid and α-muricholic acid) and the secondary bile acids (lithocholic acid, deoxycholic acid, ursodeoxycholic acid, hyodeoxycholi

Lipotoxicity is a presumed pathogenetic process whereby elevated circulating and stored lipids in Type 2 Diabetes cause pancreatic β-cell failure. To resolve the underlying molecular mechanisms, we exposed clonal INS-1 832/13 β-cells to palmitate for 48 h. We observed elevated basal insulin secretion but impaired glucose-stimulated insulin secretion in palmitate-exposed cells. Glucose utilization

Increases in striatal activity have been suggested to mediate training-related improvements in working-memory ability. We investigated the temporal dynamics of changes in task-related brain activity following training of working memory. Participants in an experimental group and an active control group, trained on easier tasks of a constant difficulty in shorter sessions than the experimental group

Why do certain ministers remain in their post for years while others have their time in office cut short? Drawing on the broader literature on portfolio allocation, this article argues that the saliency of individual portfolios shapes ministerial turnover. The main argument is that ministerial dismissals are less likely to occur the higher the saliency attributed to the ministerial portfolio since

The role of nurses and technicians in the treatment of ST-elevation myocardial infarction (STEMI) by primary percutaneous coronary intervention (PPCI) is vital for the success of the multidisciplinary Heart Team. Several editorials have emphasised the importance of a holistic treatment which links each step of care to the next, a chain that is essential for quality and efficacy in the management o

The review essay compares two different positions on climate geoengineering, providing an overview of the authors' main points and a subsequent analysis of their arguments.

Flow characteristics and heat transfer performances of rectangular dimpled channels with secondary protrusions are numerically analyzed and compared in this research work. The special arrangement is a conventional dimpled cavity with a small-size secondary protrusion placed upstream of the dimple. The objective is to determine the most optimal configuration for augmenting heat transfer rates with

We present a systematic comparison of conventional small-angle X-ray scattering (SAXS) with the relatively new real-space technique, spin-echo small-angle neutron scattering (SESANS). We apply both techniques to colloidal suspensions where the particles interact as hard spheres, with electrostatic repulsions, or with polymer-induced depletion attractions. We successfully model the data sets with t

Cellobiose dehydrogenase (CDH) is a monomeric extracellular flavocytochrome composed of a catalytic dehydrogenase domain (DHCDH) containing flavin adenine dinucleotide (FAD), a cytochrome domain (CYTCDH) containing heme b, and a linker region connecting the two domains. In this work, the effect of deglycosylation on the electrochemical properties of CDH from Phanerochaete chrysosporium (PcCDH) and

Intact pharyngeal function and coordination of breathing and swallowing are essential for airway protection and to avoid respiratory complications. Postoperative pulmonary complications caused by residual effects of neuromuscular-blocking agents occur more frequently in the elderly. Moreover, elderly have altered pharyngeal function which is associated with increased risk of aspiration. The purpos

There are many instruments assessing the wellbeing of staff, but far from all have been psychometrically investigated. When evaluating supportive interventions directed toward nurse assistants in residential care, valid and reliable instruments are needed in order to detect possible changes. The aim of the study was to investigate validity in terms of data quality, construct validity, convergent a
