Automated de novo phasing and model building of coiled-coil proteins.

Models generated by de novo structure prediction can be very useful starting points for molecular replacement for systems where suitable structural homologues cannot be readily identified. Protein-protein complexes and de novo-designed proteins are examples of systems that can be challenging to phase. In this study, the potential of de novo models of protein complexes for use as starting points fo

Adnexal masses difficult to classify as benign or malignant using subjective assessment of gray scale and Doppler ultrasound findings: logistic regression models do not help.

AIM: To develop a logistic regression model that can discriminate between benign and malignant adnexal masses perceived to be difficult to classify by subjective evaluation of gray scale and Doppler ultrasound findings (subjective assessment) and to compare its diagnostic performance with that of subjective assessment, serum CA 125 and the risk of malignancy index (RMI). METHODS: We used the 3511

Microclimate in Hot Dry Damascus: The Influence of the Urban Environment on Human Perception

There is a broad recognition that microclimatic conditions contribute to the quality of life in cities. A favorable microclimate has a positive influence on both commercial and social activities. The aim of this study is to investigate the relationship between the human being and the surrounding thermal environment in terms of thermal acceptability, physical quality of the place, emotional state a

Team Interactions in Specialized Palliative Care Teams: A Qualitative Study

Background: Teamwork is a standard of care in palliative care and that is emphasized by leading organizations. When interdisciplinary teams communicate their varied assessments, outcomes may be more than additive due to the synthesis of information. Interprofessionality does not guarantee multidimensionality in health care interventions, however, and that interprofessional teams promote collaborat

Daily life and life quality 3 years following prostate cancer treatment.

Knowledge of experiences from prostate cancer is sparse in a longitudinal perspective. From a nursing perspective, results from combined qualitative and quantitative studies are lacking however would present the broadest knowledge base for best practice. Present descriptions of medical-physical symptoms such as urinary, bowel and sexual dysfunction from quantitative inquiries need be complemented

A New Model for Assessment of Change in Visual Function in Diabetes

The purpose of this thesis was to determine whether perimetry using a new model to interpret deterioration or improvement in the visual field can be employed to assess change in visual function over time in diabetes. Diabetic retinopathy has long been considered a microvascular disease, but it is still a matter of debate to what extent diabetes also affects retinal neurons. Visual acuity is routi

Weight loss after stroke: a population-based study from the Lund Stroke Register.

BACKGROUND AND PURPOSE: Data on the prevalence and indicators of weight loss in population-based groups of stroke survivors are scarce. We aimed to find the predictors and indicators of weight loss >3 kg as a possible marker of malnutrition after stroke. METHODS: We registered weight at baseline, after 4 months, and 1 year later in 305 survivors from a population-based cohort of first-ever st

Modifications of Hippocampal Circuits and Early Disruption of Adult Neurogenesis in the Tg2576 Mouse Model of Alzheimer's Disease

At advanced stages of Alzheimer's disease, cognitive dysfunction is accompanied by severe alterations of hippocampal circuits that may largely underlie memory impairments. However, it is likely that anatomical remodeling in the hippocampus may start long before any cognitive alteration is detected. Using the well-described Tg2576 mouse model of Alzheimer's disease that develops progressive age-dep

Self-energy and spectral function of Ce within the GW approximation

To investigate how far the GW approximation can treat systems with strong on-site correlations, we perform calculations of the self-energies and spectral functions of alpha-and gamma-Ce within the GW approximation. For this strongly correlated material, the screened interaction exhibits a complex and rich structure which is attributed to strong particle-hole transitions involving localized 4f stat

Both Low and High Serum IGF-1 Levels Associate With Increased Risk of Cardiovascular Events in Elderly Men

Context: Most previous prospective studies suggest that low serum IGF-1 associates with increased risk of cardiovascular disease (CVD) events whereas other studies suggest that high serum IGF-1 associates with increased risk of CVD events. Objective: We tested the hypothesis that not only low, but also high serum IGF-1 levels associate with increased risk of CVD events in elderly men. Setting and

Contextual and Analytic Qualities of Research Methods Exemplified in Research on Teaching

The aim of the present article is to discuss contextual and analytic qualities of research methods. The arguments are specified in relation to research on teaching. A specific investigation is used as an example to illustrate the general methodological approach. It is argued that research methods should be carefully grounded in an understanding of the nature of the investigated phenomena. This mak

Optimal Policies for Inventory Systems with Lateral Transshipments

Using lateral transshipments can be beneficial in order to improve service levels and to reduce system costs. This paper deals with a single-echelon inventory system with two identical locations. Demands are generated by stationary and independent Poisson processes. In general, if a demand occurs at a location and there is no stock on hand, the demand is assumed to be backordered or lost. However,

Death causes in breast cancer patients

Background: Due to improved outcomes in breast cancer (BCa), the proportion of affected women dying of other causes has increased. Thus, a better survival of BCa requires knowledge of other causes of death. Materials and methods: Data on the population, cancers, and causes of death were gathered from the nationwide Swedish Family-Cancer Database, enrolling similar to 3.68 million Swedish women. A

Mice expressing L345P mutant desmin exhibit morphological and functional changes of skeletal and cardiac mitochondria

Desmin mutations underlie inherited myopathies/cardiomyopathies with varying severity and involvement of the skeletal and cardiac muscles. We developed a transgenic mouse model expressing low level of the L345P desmin mutation (DESMUT mice) in order to uncover changes in skeletal and cardiac muscles caused by this mutation. The most striking ultrastructural changes in muscle from DESMUT mice were

On the Reliability of Mapping Studies in Software Engineering

Background: Systematic literature reviews and systematic mapping studies are becoming increasingly common in software engineering, and hence it becomes even more important to better understand the reliability of such studies. Objective: This paper presents a study of two systematic mapping studies to evaluate the reliability of mapping studies and point out some challenges related to this type of
