The recent introduction of entry inhibitors in the clinic as components of antiretroviral treatment has heightened the interest in coreceptor use of human immunodeficiency virus type 1 (HIV-1). Viruses using CCR5 as coreceptor (R5 viruses) are generally present over the entire course of infection whereas viruses using the CXCR4 coreceptor (R5X4/X4 viruses) emerge in about 50% of infected individua

Cardiovascular disease remains as the leading cause of death in the developed world. However, there is limited knowledge about how cardiovascular risk factors actually cause vascular disease. Traditional cardiovascular risk factors include increased circulating levels of low-density lipoproteins, cigarette smoking and hypertension (both strongly related to arterial wall injury), inflammation and a

Multiple sequence alignment (MSA) is an essential prerequisite for many sequence analysis methods and valuable tool itself for describing relationships between protein sequences. Since the success of the sequence analysis is highly dependent on the reliability of alignments, measures for assessing the quality of alignments are highly requisite.

Abstract in Undetermined Bone is dynamic tissue undergoing changes in its composition, structure and functional properties during growth. It has been proposed that especially changes in the collagen phase of bone are responsible for making the bone more fragile, and potentially less viscoelastic with age. Hence, robust methods to measure viscoelasticitiy are needed. This study aimed to characteriz

Abstract While outcome studies in pediatric obesity have received considerable attention, research on different components of effective interventions remains limited. Little is known which psychological method (i.e., behavior modification, cognitive behavior therapy and family therapy) is most useful or how the choice of program delivery (group/individual) influences the intervention outcomes. Gro

Objective Cognitive dysfunction is common in multiple sclerosis (MS), but long-term data on cognition in patients with clinically isolated syndromes are sparse. Methods We determined cognitive functions in 22 patients 44-75 years old diagnosed with optic neuritis 24-31 years earlier but had no further clinical bouts and had not progressed clinically to MS. We used a neuropsychological test battery

Background: Previous studies on associations between reduced lung function and cardiovascular disease (CVD) have mainly been based on forced expiratory volume in 1-s (FEV(1) ) and vital capacity (VC). This study examined potential associations between five different lung function variables and plaques in the internal carotid artery (ICA). Methods: Subjects (n = 450) from a previous population-base

The assessment of residue conservation in a multiple sequence alignment is a central issue in bioinformatics. Conserved residues and regions are used to determine structural and functional motifs or evolutionary relationships between the sequences of a multiple sequence alignment. For this reason, residue conservation is a valuable measure for database and motif search or for estimating the qualit

OBJECTIVE: This study was undertaken to study the association between the times spent on sports activities and leisure time physical activity in the first and early second trimester of pregnancy and the risk of preterm delivery. STUDY DESIGN: Population-based follow-up study of 5749 healthy pregnant women who delivered in Aarhus University Hospital, Denmark. RESULTS: Women who practiced more than

OBJECTIVE: To determine whether perturbations of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) were associated with the presence of chronic widespread pain (CWP) in men. METHODS: The European Male Ageing Study (EMAS) is an 8-center population-based study of men aged 40-79 years recruited from population registers. A questionnaire asked about the presence and duration of

There are ethnic differences in the incidence of venous thromboembolism. This is the first nationwide study to examine whether there is an association between country of birth in first-generation immigrants and first hospitalisation for venous thrombosis (VT) and pulmonary embolism (PE), and to study whether a similar association exists in second-generation immigrants.

Reading comprehension and three aspects of working memory—general, visuospatial and phonological—was assessed in 41 children with hearing loss: 23 with cochlear implants and 18 with hearing aids. Performance on these tests was compared between the two groups of children with hearing loss and also related to that of 55 children with typical hearing. All children were between 6 and 14 years of age.

A survey, admittedly selective and personal, of the literature of research into various aspects of the history of the book in Sweden from 1990. With bibliographical notes.
