Human immunodeficiency virus type-2 (HIV-2) infected individuals develop immunodeficiency with a considerable delay and transmit the virus at a lower rate as compared to HIV-1 infected. Conceivably, comparative studies on immune responsiveness of the HIV-1 and HIV-2 infected hosts may help to explain differences in pathogenesis and transmission between the two types of infection. Previous studies

This study addresses the question of whether Vietnamese L1 speakers make an adequate distinction in tonal patterns when producing two tonal accent words in their L2, Swedish. Both languages use tonal features to distinguish lexical meaning. Some previous studies suggest that a lexical tonal L1 may provide L2 learners an advantage in perceptually discriminating between different tones in another to
Objectives. The low molecular weight heparin, Dalteparin, shortens human labor time. The aim of this study was to investigate if the mechanism behind this effect involves myometrial contractility and cervical ripening and if the anticoagulative activity is necessary for its effect. Design. Experimental in vitro study. Setting. Lund University and Karolinska Institute, Sweden. Methods. The effect o
We assessed the role of vegetation and hydrology in the Si cycle in the Okavango Delta. Our results show a large storage of biogenic Si (BSi) in vegetation and the sediments. The biological storage is among the highest observed so far for any ecosystem worldwide. Floodplain vegetation accumulates similar amounts of BSi in both the temporary floodplains and the permanent floodplains, with most valu
The literature on the relationship between the size of government and economic growth is full of seemingly contradictory findings. This conflict is largely explained by variations in definitions and the countries studied. An alternative approach – of limiting the focus to studies of the relationship in rich countries, measuring government size as total taxes or total expenditure relative to GDP an
The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic respons
The high-spin rotational bands in Hf-168 and the triaxial bands in Lu nuclei are analyzed using the configuration-constrained cranked Nilsson-Strutinsky (CNS) model. Special attention is given to the up-sloping extruder orbitals. The relative alignment between the bands which appear to correspond to triaxial shape is also considered, including the yrast ultrahigh-spin band in Er-158. This comparis
The Swedish teaching profession, Nazism and Soviet Communism from 1933 to 1945 The “Democratic School” was a concept that Swedish teachers used regularly to describe the school that they had participated in building up. In the interwarperiod, the Democratic School was confronted with two major challenges, i.e. German Nazism and Soviet Communism. This thesis has, in a comparative form, investigate
This study investigated genetic causes of Parkinson's disease (PD) and parkinsonism in southern Sweden. The extensive Lister Family with parkinsonism caused by duplications and triplications of the gene for alpha-synuclein (SNCA) was studied. Clinical, genetic and genealogical data were compiled and evaluated. Thirty-five family members with parkinsonism were identified. They share a characteristi
We calculate potential-energy surfaces as functions of spheroidal (epsilon(2)), hexadecapole (epsilon(4)), and axial-asymmetry (gamma) shape coordinates for 7206 nuclei from A = 31 to A = 290. We tabulate the deformations and energies of all minima deeper than 0.2 MeV and of the saddles between all pairs of minima. The tabulation is terminated at N = 160. Our study is based on the FRLDM macroscopi
The influence of Thermomyces lanuginosus lipase (TLL) on the phase behaviour of liquid-crystalline phases of aqueous phytantriol as well as conformational changes of TLL entrapped in the cubic Q(230) phase have been studied by small angle X-ray diffraction (SAXD), FT-Raman, and FT-IR techniques. It was found that the lipidic Q(230) Phase is able to accommodate up to 10 wt.% of TLL, and the tempera
Popular Abstract in Swedish En av de största orsakerna till svårt handikapp och död i västvärlden är traumatisk hjärnskada som uppstår till följd av våld mot huvudet. Utav vuxna och barn är det generellt sett barn som klarar sig bättre efter våld mot huvudet men det är ändå till stor del barn som söker akutmottagning p.g.a. skallskada. De flesta av barnen har en så kallad lätt skallskada (ca 90 %)Traumatic head injury is one of the leading causes to severe morbidity and death among children. Specific and national management guidelines for pediatric head injuries are lacking in Sweden, and management routines are consequently based on adult guidelines or local guidelines. The objectives of this thesis were to investigate the current management of pediatric head injury in Sweden and to explo
OBJECTIVE: To describe the frequency of symptoms and associated conditions among screening-detected celiac disease (CD) cases and non-CD children and to evaluate questionnaire-based case-finding targeting the general population. METHODS: In a population-based CD screening of 12-year-olds, children and their parents completed questionnaires on CD-associated symptoms and conditions before knowledge
Background and purpose The Scandinavian Sarcoma Group (SSG) XIV protocol was based upon the organisations experience from 3 previous osteosarcoma trials and was considered best standard of care for patients with extremity localised, non-metastatic osteosarcoma. We report the outcome of this protocol. Patients and methods From March 2001 to April 2005, 63 patients recruited from 10 centres in Finla
Sub-Sahara Africa is considered to be most vulnerable to climate variability including flooding. The frequency and severity of floods in Northern Ghana over the last decade has increased considerably. Through qualitative modelling the paper explores the impact of floods on natural resource dependent communities in Northern Ghana. Simplified causal loop diagrams are used to conceptualise flood-indu
Purpose of this paper The purpose of this paper is to propose a framework for describing and analyzing misalignments in supply chain management related to changes in supply chain structures, processes, and management components. Design/methodology/approach Based on the systems approach, a single-case study including several embedded cases from the same supply chain was deployed. This was done acc
Equinatoxin II (EqtII), a eukaryotic pore-forming toxin, lyses cell membranes through a mechanism involving the insertion of its N-terminal α-helix into the membrane. EqtII pore formation is dependent on sphingomyelin (SM), although cholesterol (Chol) and membrane microdomains have also been suggested to enhance its activity. We have investigated the mechanism of EqtII binding and insertion by usi
