OBJECTIVE: The reason that only a minority of smokers develop chronic obstructive pulmonary disease (COPD) is still largely unknown. Glycosylation defects are involved in the pathological mechanisms in cystic fibrosis (CF), where chronic progressive obstructive lung disease dominates the clinical picture. Whether defects of protein glycosylation occur in COPD has not previously been examined. Incr

Three experiments were conducted to study on a more fine-grained level how processing a picture facilitates learning from text. In Experiment 1 (N = 85), results from a drawing task revealed that the global spatial structure of a pulley system picture was extracted even from its brief inspection (for 600 ms, 2 s). In Experiment 2 (N = 105), students who initially inspected the pulley system pictur

Aims: Multiple lines of evidence have implicated beta-amyloid (A beta) in the pathogenesis of Alzheimer's disease (AD). However, the mechanism(s) whereby A beta is involved in the disease process remains unclear. The dominant hypothesis in AD has been that A beta initiates the disease via toxicity from secreted, extracellular A beta aggregates. More recently, an alternative hypothesis has emerged

Women in the UK prefer the faces of men with low levels of the stress hormone cortisol, and the relationship is moderated by the sex hormone testosterone. In a Latvian sample, however, women's preferences were not affected by cortisol, and the interaction with testosterone differed from that of the UK. To further explore cross-cultural variation in preferences for facial cues to sex- and stress-ho

Ultrasound reflection and backscatter parameters are related to mechanical and structural properties of bone in vitro. However, the potential of ultrasound reflection and backscatter measurements has not been tested with intact human proximal femurs ex vivo. We hypothesize that ultrasound backscatter can be measured from intact femurs and that the measured backscattered signal is associated with c

This review paper addresses the role of green roofs in urban drainage considering both management of water quantity and quality. Results from investigation of full scale installations as well as from laboratory models are reviewed. The following factors affecting runoff dynamics from green roofs are discussed: type of green roof and its geometrical properties (slope): soil moisture characteristics

The coordination environment of uranyl in water has been studied using a combined quantum mechanical and molecular dynamics approach. Multiconfigurational wave function calculations have been performed to generate pair potentials between uranyl and water. The quantum chemically determined energies have been used to fit parameters in a polarizable force field with an added charge transfer term. Mol

Bygg rätt från början är ett centralt motto om man vill bygga ett sunt hus. Fuktdimensionering är en hjälp för att lyckas med detta. Fukt orsakar ofta dålig innemiljö och kostnaden för att åtgärda fuktskador uppgår till miljardbelopp årligen. Genom att använda den kunskap som finns skulle de vanligaste fuktproblemen kunna undvikas. Kunskapen finns dokumenterad bl a i serien Fuktsäkerhet i byggnade

Popular Abstract in Swedish Prostatacancer är den bland män vanligast förekommande cancerformen i Sverige. Under 2003 diagnostiserades 9882 nya fall. Sjukdomen drabbar framför allt äldre individer; många män är 70 år gamla eller äldre när de får diagnosen. Sjukdomsförloppet kan vara mycket varierande. Hos många är tumörtillväxten långsam, men sjukdomen kan också utvecklas snabbt. Många patienter lConcentrations of prostate-specific antigen (PSA) and human kallikrein 2 (hK2) were investigated in blood samples that had been obtained from men who were diagnosed with prostate cancer (PCa) decades later. The studies were based on a cohort comprising 22,444 men who, in 1974?1986, were early middle aged and represented a non-PCa-screened population. The results clearly demonstrate a very strong c

Neutrophils are involved in development of acute pancreatitis (AP), but it is not clear how neutrophil-induced tissue damage is regulated. In addition to secreting antimicrobial compounds, activated neutrophils eliminate invading microorganisms by expelling nuclear DNA and histones to form extracellular web-like structures called neutrophil extracellular traps (NETs). However, NETs have been repor

This article complements existing studies on the incumbency effects of conditional cash transfers (CCTs) by analysing the principal mechanisms by which Mi Familia Progresa (MIFAPRO) in Guatemala became increasingly politicised through clientelistic vote buying and threats of programme expulsion in case of non-electoral support. It finds that MIFAPRO constitutes an emblematic case with mixed effect

Salvage hypospadias surgery is performed after failed primary reconstruction. Several treatment strategies have been suggested, all with pros and cons. The aim of this study was to evaluate our treatment algorithm for primary hypospadias repair applied to secondary cases in which a salvage procedure is indicated and, most importantly, local tissue is present. The algorithm was applied to 36 consec

Popular Abstract in Swedish Denna rättssociologiska studie handlar om tvångsomhändertagna missbrukares rättssäkerhet under tiden i vård. Författaren undersöker begreppet rättssäkerhet i förhållande till tvångsvårdens verkställighet på så kallade LVM-hem i syfte att finna en begreppsdefinition som är operationaliserbar vid studier av rättssäkerhetens upprätthållande. Med utgångspunkt i resultaten Compulsory treatment and care is regulated by the Care of Alcoholics and Drug abusers Act (Lag (1988:870) om vård av missbrukare i vissa fall, LVM). The regulation's main purpose is to motivate persons with addictive problems to voluntarily participate in the treatment of their problems. The compulsory care shall continue for a maximum period of six months in special treatment centres (the so-call

Quantitative structural information about epitaxial arrays of nanowires are reported for a InAs/InP longitudinal heterostructure grown by chemical beam epitaxy on an InAs (111)(B) substrate. Grazing incidence X-ray diffraction allows the separation of the nanowire contribution from the substrate overgrowth and gives averaged information about crystallographic phases, epitaxial relationships (with
