The demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. A thin film containing pn-junction nanowires can convert light with an efficiency comparable to traditional planar cells, while using a fraction of the material, and thus reduce costs.

Autochthonous blockfield mantles may indicate alpine surfaces that have not been glacially eroded. These surfaces may therefore serve as markers against which to determine Quaternary erosion volumes in adjacent glacially eroded sectors. To explore these potential utilities, chemical weathering features, erosion rates, and regolith residence durations of mountain blockfields are investigated in the

ABSTRACT: BACKGROUND: The two-step dilute acid hydrolysis (DAH) of softwood is costly in energy demands and capital costs. However, it has the advantage that hydrolysis and subsequent removal of hemicellulose-derived sugars can be carried out under conditions of low severity, resulting in a reduction in the level of sugar degradation products during the more severe subsequent steps of cellulose hy

Objective To compare drug survival on adalimumab, etanercept and infliximab in patients with rheumatoid arthritis (RA). Methods Patients with RA (n=9139; 76% women; mean age 56 years) starting their first tumour necrosis factor (TNF) inhibitor between 2003 and 2011 were identified in the Swedish Biologics Register (ARTIS). Data were collected through 31 December 2011. Drug survival over up to 5 ye

Objective. Helicobacter pylori infection is an established risk factor for non-cardia gastric adenocarcinoma. Infection with H. pylori strains harbouring the cagA pathology island may augment this association. H. pylori infection may at the same time reduce the risk for oesophageal carcinoma. However, prospective data on the association between CagA seropositivity and gastric or oesophageal carcin

BACKGROUND: Reduced lung function has been associated with increased rates of myocardial infarction. Whether the occurrence and prognostic significance of ventricular arrhythmia is related to lung function is largely unknown. METHODS AND RESULTS: We performed a population-based study of 68-year-old men without a history of stroke or myocardial infarction; 402 men participated. Mortality and corona

Objective: The concentration of the complex between activated protein C (APC) and protein C inhibitor (PCI) is a measure of thrombin generation. We studied whether it can provide information useful for the diagnosis and treatment of arterial vascular disease. Methods: Blood was obtained from 429 vascular patients admitted consecutively during September 2004 to March 2005. The APC-PCI complex was m

Popular Abstract in Swedish Missbrukande kvinnor och mammor har ofta fördömts av samhället och av människor i sin omgivning. De har setts som ansvarslösa kvinnor och olämpliga mammor utifrån en samhällssyn, att barn och missbruk inte går ihop. De livshistoriska intervjuerna med missbrukande kvinnor och mammor, som avhandlingen bygger på visar, att kvinnorna både vill vara respektabla och ta väl haThe aim of the dissertation is to describe the conditions under which substance abusing women live with regard to their families, the substance abuse and treatment. The interaction between the substance abusing women and the institutional expectations is analysed from gender and class perspective. The dissertation is based on interviews with two groups of substance abusing women: 12 mothers, livin

In an attempt to identify novel susceptibility genes predisposing to early-onset diabetes (EOD), we performed a genome-wide scan using 433 markers in 222 individuals (119 with diabetes) from 29 Scandinavian families with ≥2 members with onset of diabetes ≤45 years. The highest nonparametric linkage (NPL) score, 2.7 (P < 0.01), was observed on chromosome 1p (D1S473/D1S438). Six other regions on chr

Purpose: To examine whether panretinal photocoagulation for severe non-proliferative retinopathy in type 1 diabetes patients could halt the progression of retinopathy with subsequent vitreous haemorrhages and visual impairment. Methods: During a 10-year follow-up study period of 344 type 1 diabetes patients, 81 subjects went through panretinal photocoagulation. Forty patients were treated for sev

OBJECTIVES: To clarify whether the intensity of exposure to organic acid anhydrides (OAAs) is associated with the risk of sensitisation to these allergens. METHODS: The investigations were carried out in three different manufacturing plants (A, B, and C) where OAAs were used in the production of epoxy resins. Methyltetrahydrophthalic acid anhydride (MTHPA) was used in all three plants. The exposur

Objectives To describe the endosonographic image of the anal sphincter 2-7 days after delivery in women who had undergone a primary repair of an obstetric sphincter tear. Methods Forty-eight women who had suffered a third- or fourth-degree sphincter tear at delivery and had undergone primary sphincter repair were examined with endoanal sonography 2-7 days after delivery. A score from 0 to 16 was

Leptin is a key biological marker related to energy balance and development of diabetes and cardiovascular diseases. Its levels are increased in populations with a high degree of the metabolic syndrome. Life history of evolution has, however, largely taken place under the ecological context of hunting and gathering. In this study, we explored whether the first steps of transition to sedentary agri

OBJECTIVE—To examine the effects of dipeptidyl peptidase-IV (DPP-4) inhibition on meal-related β-cell function and insulin sensitivity over 52 weeks in type 2 diabetes. RESEARCH DESIGN AND METHODS—In a 12-week core study, placebo (n = 51) or vildagliptin (n = 56; 50 mg OD) was added to metformin treatment (1.5–3.0 mg/day). A 40-week extension followed in 71 patients. Meal tests were performed at

OBJECTIVE Patients with latent autoimmune diabetes in adults (LADA) express autoantibodies against the 65-kDa isoform of GAD (GADA). Intervention with recombinant human GAD65 formulated with aluminium hydroxide (GAD-alum) given twice subcutaneously to LADA patients at intervals of 4 weeks was safe and did not compromise beta-cell function in a Phase II clinical trial. GADA affinity has been shown

Background: Frontotemporal dementia (FTD) is recognised as a clinically and morphologically heterogeneous group of interrelated neurodegenerative conditions. One of the subtypes within this disease spectrum is the behavioural variant FTD (bvFTD). This is known to be a varied disorder with a mixture of tau-positive and tau-negative underlying pathologies. The other subtypes include semantic dementi

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen i världen bland kvinnor och bara i Sverige insjuknar varje år runt 7000 personer. Vi vet att omkring 10-15% av fallen troligen beror på ärftliga faktorer och det har under senare tid gjorts stora insatser för att klargöra exakt vilka arvsanlag som har betydelse för utveckling av sjukdomen. Under början av 90-talet identifieradeHereditary breast cancer constitutes a considerable fraction of the total number of breast cancer cases occurring each year. Up until recently very few breast cancer predisposing genes were known, but many new common polymorphisms contributing to increased cancer susceptibility are continuously being identified. This thesis has focused on familial breast cancer and identifying as well as investi

Background: High expression of the polymeric immunoglobulin receptor (PIGR) has previously been associated with a favourable prognosis in a few cancer forms, but its expression and relationship with clinical outcome in epithelial ovarian cancer (EOC) has not yet been reported. The aim of this study was therefore to examine the clinicopathological correlates and prognostic significance of PIGR expr

Background: Metabolic syndrome (MetS) remains a controversial entity. Specific clusters of MetS components - rather than MetS per se - are associated with accelerated arterial ageing and with cardiovascular (CV) events. To investigate whether the distribution of clusters of MetS components differed cross-culturally, we studied 34,821 subjects from 12 cohorts from 10 European countries and one coho
