Emergence of human immunodeficiency virus type 1 (HIV-1) populations that switch or broaden coreceptor usage from CCR5 to CXCR4 is intimately coupled to CD4(+) cell depletion and disease progression toward AIDS. To better understand the molecular mechanisms involved in the coreceptor switch, we determined the nucleotide sequences of 253 V1 to V3 env clones from 27 sequential HIV-1 subtype B isolat
Aim: To identify maternal prenatal and postnatal smoking as risk factors for psychosocial behaviour problems in Swedish preschool children. Methods: This prospective, longitudinal population study compared mothers' self-reported smoking during pregnancy and when the child was 3 mo old with behaviour problems according to Achenbach's Child Behavior Checklist at 3 y ( 1428 children) and 5.5 y of age
There are several approaches to using nonstiff implicit linear multistep methods for solving certain classes of semi-explicit index 2 DAEs. Using β-blocked discretizations (Arevalo et al., 1996) Adams-Moulton methods up to order 4 and difference corrected BDF (Soderlind, 1989) methods up to order 7 can be stabilized. As no extra matrix computations are required, this approach is an alternative to
Neuroblastoma is a childhood tumor derived from precursor or immature cells of the sympathetic nervous system. Neuroblastomas show a tremendous clinical heterogeneity, encompassing truly benign as well as extremely aggressive forms. In vivo as well as in vitro data have shown that the degree of sympathetic neuronal tumor cell differentiation influences patient outcome. Unraveling mechanisms govern
Antibody response to Campylobacter jejuni/coli (CJC) was investigated, using an enzyme-linked immunosorbent assay, ELISA. With a mixture of lipopolysaccharide from two CJC strains as antigen in ELISA, all 24 tested rabbit anti-CJC sera showed high antibody levels. However, only 70% of sera from patients with Campylobacter enteritis demonstrated an antibody response against the combined LPS antigen
The clinical importance of asymptomatic proximal and distal deep vein thrombosis (DVT) remains uncertain and controversial. The aim of this retrospective, post-hoc analysis was to examine mortality and risk factors for development of proximal DVT in hospitalized patients with acute medical illness who were recruited into a randomized, prospective clinical trial of thromboprophylaxis with daltepari
The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create gen
Popular Abstract in Swedish Avhandlingen är en granskning av ett antal psykologiska metoder i syfte att förbättra bedömning/diagnostik av två olika tillstånd förknippade med kontakt med kemikalier: (1) kronisk nedsättning av hjärnfunktion till följd av långvarig kontakt med lösningsmedel i yrket (toxisk encefalopati, förkortat TE), och (2) överkänslighet för kemikalielukter av okända orsaker (eng.The dissertation deals with psychological methods aimed at improving the understanding and assessment of two disorders related to contact with chemicals: solvent-induced chronic toxic encephalopathy (TE) and multiple chemical sensitivity (MCS). The main aim of Paper I was to study whether the addition of some newer psychological tests of complex attention and executive functions to a traditional
Packaging and the role it plays in supply chain efficiency is overlooked in most design and development research. An opportunity exists to meet the needs of supply chains to increase efficiency. This research presents three propositions on how to reduce the gap between supply chain needs and satisfaction in interaction with the product and packaging system. It also proposes a supply chain focused
Popular Abstract in Swedish Med dagens alla transporter finns det ett mycket stort behov av tillgång till billigt och miljövänligt drivmedel. Det bränsle som används i särklass mest är bensin framställd från råolja. Ett problem med bensinen är att den inte tillverkas från förnyelsebara råvarukällor. Detta innebär att när oljan tar slut så går det inte att tillverka mer bensin. Däremot är det idag In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. Several of these compounds might act as inhibitors during the fermentation of the sugars to ethanol. Thus, in order to obtain high etha
During recent years we have seen several large-scale crises. The 9/11 terror attacks, tsunamis, storms, floods and bombings have all caused a great deal of damage. A common factor in these crises has been the need for information and one important source of information is usually Web sites. In this work we investigate and design an overload control system for Web sites that are vital in crises. Th
In very-large multiple-input multiple-output (MIMO) systems, the BS (base station) is equipped with very large number of antennas as compared to previously considered systems. There are various advantages of increasing the number of antennas, and some schemes would require handling large matrices for joint processing (pre-coding) at the base station. The dirty paper coding (DPC) is an optimal pre-
