We report the structure of a novel tetrameric form of the lactose repressor (LacI) protein from Escherichia coli refined to 2.1 A resolution. The tetramer is bound to 1.6-hexanediol present in the crystallization solution and the final R(free) for the structure is 0.201. The structure confirms previously reported structures on the monomer level. However, the tetramer is much more densely packed. T

To support occupations outside the home for older people with functional limitations it is important to understand how the person, environment, and occupations influence performance. Therefore the purpose of this study was to describe how very old people experience occupational performance outside the home. Twenty-one single-living, very old persons, above 80 years, were strategically selected and

The objective was to examine the prevalence of HIV-1, HIV-2 and 10 other sexually transmitted infections (STIs), and to explore the relationship between HIV and those STIs in women attending two sexual health clinics in Bissau, Guinea-Bissau. In all, 711 women with urogenital problems were included. Clinical examination was performed and HIV-1, HIV-2, human T-cell lymphotropic virus (HTLV)-1, HTLV

A fiber optic based continous wave laser setup has been developed to record the 5-aminolevulinic (5-ALA) induced Protoporfyrin IX (PpIX) fluorescence signals from cerebral gliomas. To reduce the energy delivered to the tissue as well as suppression of the ambient lamp artifact from the recorded spectra, a pulsed laser setup has been developed and evaluated. This setup has been calibrated and first

BACKGROUND: Current health measurement instruments tend to measure aspects of ill-health rather than health in general. There is a need for a salutogenic perspective when describing health and developing a health measurement instrument. The aim of this article is to present the development process and quality assessment of a salutogenic health indicator scale. METHODS: A description of health, ema

Since Aerococcus sanguinicola was designated as a species in 2001, only a few cases of bacteremia have been reported. The aim with this study was to describe the clinical presentation of A sanguinicola bacteremia and to determine the antibiotic susceptibility and the capacity of the bacteria to form biofilm and to induce platelet aggregation.

The aim was to investigate the relationship between creativity and hemispheric asymmetry, as measured by regional cerebral blood ¯ow (rCBF). Two groups, each consisting of 12 healthy male subjects, who got either very high or low scores on a creativity test, were pre-selected for the rCBF investigation. rCBF was measured during rest and three verbal tasks: automatic speech (Auto), word ¯uency (FAS

OBJECTIVE: To estimate the incremental costs to public payers for patients with ankylosing spondylitis (AS) of working age compared with reference subjects from the general population. METHODS: We investigated total costs for 3 years (2005-2007) in 116 outpatients under 66 years of age with AS attending rheumatological care in Malmö, Sweden. Mean (SD) age was 46 (11) years and mean (SD) disease du

Functional coagulation analyses like Sonoclot and thromboelastography have not been evaluated during perioperative autotransfusion. We have prospectively studied three different transfusion regimes in 45 patients undergoing total hip arthroplasty. Blood losses were replaced either with heterologous erythrocyte concentrate (group I), intra- and postoperative autotransfusion of blood salvaged with c

PURPOSE: The purpose of this study was to identify genetic aberrations contributing to clinical aggressiveness of malignant peripheral nerve sheath tumors (MPNSTs). PATIENTS AND METHODS: Samples from 48 MPNSTs and 10 neurofibromas were collected from 51 patients with (n = 31) or without (n = 20) neurofibromatosis type 1 (NF1). Genome-wide DNA copy number changes were assessed by chromosomal and ar

Low aerobic fitness (maximum oxygen uptake (VO(2PEAK))) is predictive for poor health in adults. In a cross-sectional study, we assessed if VO(2PEAK) is related to a composite risk factor score for cardiovascular disease (CVD) in 243 children (136 boys and 107 girls) aged 8 to 11 years. VO(2PEAK) was assessed by indirect calorimetry during a maximal exercise test and scaled by body mass (millilite

ABSTRACT: INTRODUCTION: Aggrecanase cleavage at the 392Glu-393Ala bond in the interglobular domain (IGD) of aggrecan, releasing N-terminal 393ARGS fragments, is an early key event in arthritis and joint injuries. We determined whether synovial fluid (SF) levels of ARGS-aggrecan distinguish subjects with progressive radiographic knee osteoarthritis (ROA) from those with stable or no ROA. METHODS: W

Individual aspects of social capital have been shown to have significant associations with health outcomes. However, research has seldom tested different elements of social capital simultaneously, whilst also adjusting for other well-known health determinants over time. This longitudinal individual-level study investigates how temporal changes in social capital, together with changes in material c

Rationale, aims and objectives Studies have challenged the validity and underlying measurement model of the physical and mental component summary scores of the 36-item Short-Form Health Survey in, for example the elderly and people with neurological disorders. However, it is unclear to what extent these observations translate to physical and mental component summary scores derived from the 12-item

As a response against serious infection, there is often a need to produce more leukocytes to defend the organism against the infectious agent. In this issue of Cell Stem Cell, Goodell and colleagues (Feng et al., 2008) find a link between regulators of host defense and hematopoietic stem cells.
