We have performed a systematic study of the entropy term in the MM/GBSA (molecular Mechanics combined with generalized Born and surface area solvation) approach to calculate ligand-binding affinities The entropies are calculated by a normal mode analysis of harmonic frequencies from minimized snapshots of molecular dynamics simulations. For computational reasons, these calculations have normally b
Cell immortalization is regarded as an early and pre-requisite step in tumor development. Defining the specific genetic events involved in cell immortalization may provide insights into the early events of carcinogenesis. Nasopharyngeal carcinoma is common among the Southern Chinese population. Epstein-Barr virus (EBV) infection is associated closely with nasopharyngeal carcinoma. The involvement
Sex determination is a fundamental biological process, yet its mechanisms are remarkably diverse(1,2). In vertebrates, sex can be determined by inherited genetic factors or by the temperature experienced during embryonic development(2,3). However, the evolutionary causes of this diversity remain unknown. Here we show that live-bearing lizards at different climatic extremes of the species' distribu
Several substances, including glutamine and propionic acid but in particular butyric acid, have been proposed to be important for colonic health. β-Glucans lead to the formation of comparatively high amounts of butyric acid, and germinated barley foodstuff obtained from brewer's spent grain (BSG), containing high amounts of β-glucans and glutamine, has been reported to reduce the inflammatory resp
The article discusses influences from the Book of Isaiah upon the concluding hymn of Poimandres (Corpus Hermeticum I) and uses religio-historical information gleaned from this comparison as a basis for defending a reconstruction of this text based on Papyrus Berolinensis 9794. Various epithets and descriptions of the divine occurring in the hymn are argued to be dependent upon the titulature of YH
Abstract Background: Empowerment is essential in the rehabilitation process for people with psychiatric disabilities and knowledge about factors that may play a key role within this process would be valuable for further development of the day centre services. Objective: The present study investigates day centre attendees' perceptions of empowerment. The aim was to investigate which factors show th
Study Design. Multi-center case-control studyObjective. To investigate the prevalence of back problems in adults with idiopathic scoliosis.Summary of Background Data. Information on the prevalence of back problems in adults with idiopathic scoliosis is scarce, especially in untreated individuals, males and individuals with an age at onset of the scoliosis of less than 10 years.Methods. 1069 indivi
The role of the microbial processes governing methane emissions from tundra ecosystems is receiving increasing attention. Recently, cooperation between methanotrophic bacteria and submerged Sphagnum was shown to reduce methane emissions but also to supply CO2 for photosynthesis for the plant. Although this process was shown to be important in the laboratory, the differences that exist in methane e
Satellite observations have shown that the Asian Summer Monsoon strongly influences the upper troposphere and lower stratosphere (UTLS) aerosol morphology through its role in the formation of the Asian Tropopause Aerosol Layer (ATAL). Stratospheric Aerosol and Gas Experiment II solar occultation and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) lidar observations show
Aim: Negative Pressure Wound Therapy (NPWT) has become widely adopted over the last 15 years and over 1000 peer-reviewed publications are available describing its use. Despite this, there remains uncertainty regarding several aspects of usage. In order to respond to this gap a global expert panel was convened to develop evidence-based recommendations describing the use of NPWT. In this communicati
This paper examines the value of reducing foodborne risk. Previous research on the valuation of health risk has been dominated by the study of mortality risk. However, in most cases foodborne illnesses are non-fatal, so we focus on individuals' preferences for reducing morbidity risk, while also including a realistic, if remote, chance of death. We use a contingent valuation method on a Swedish sa
Neighborhood socioeconomic disadvantage is associated to increased individual risk of ischemic heart disease (IHD). However, the value of this association for causal inference is uncertain. Moreover, neighborhoods are often defined by available administrative boundaries without evaluating in which degree these boundaries embrace a relevant socio-geographical context that condition individual diffe
New Zealand is often seen as a leader when it comes to environmental policies, but it needs to do much more to reduce its greenhouse gas emissions.
Methods: The study population of healthy adult volunteers was divided into a sample for development of a prediction model (n = 63) and a testing sample (n = 30). Magnetic resonance imaging data were used to assess anatomical characteristics of the left ventricle: the angle between papillary muscles (PMA), the length of the left ventricle (LVL) and left ventricular mass (LVM). Twelve-lead electroca
Leukocyte telomere length (LTL) is associated with the aging process and may be related to cognitive aging. Previous studies have shown conflicting results whether LTL is affected in patients with Alzheimer's disease (AD). In this pilot study, we investigated LTL in a well-defined homogeneous mono-center population. Sixty consecutive patients admitted for cognitive impairment to a memory clinic we
Objective. This study evaluated the impact of hospital volume on local recurrence and distant metastasis in a population-based series of radical cystectomy patients in Sweden. Material and methods. All patients who underwent cystectomy for bladder cancer in 1997-2002 in Sweden and were reported to the National Bladder Cancer Registry were included. A high-volume hospital (HVH) was defined as one w
During the radiation survey of a reinstalled 10-MV linear accelerator in an old radiation treatment facility, high dose rates of neutrons were observed. The area outside the maze entrance is used as a waiting room where patients, their relatives and staff other than those involved in the actual treatment can freely pass. High fluence rates of neutrons would cause an unnecessary high effective dose
The paper aims to provide a systematic overview of the drivers and barriers for food retailers to implement corporate supply chain responsibility. The research is based on a literature analysis and semi-structured interviews with food retailers, with primary focus on Swedish conventional supermarket chains. The paper contributes to the existing body of research by providing the food retailers’ own
