Background Although the role of smoking as a risk factor for emphysema in α1-antitrypsin deficiency (AATD) is well known, never-smokers with severe AATD may also develop lung disease, ranging from mild asymptomatic disease to severe emphysema. Methods We performed a cross-sectional and observational study to analyse the characteristics of the population of never-smoker severe AATD (genotype) indiv

Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. Although biocatalysts are considered advantageous, since they operate under mild conditions regarding temperature and pH and e

Urban pluvial flooding threatens transport accessibility, yet the spatial factors such as elevation, vegetation, and road density associated with accessibility loss remain insufficiently understood. This study assessed changes in nearest-facility travel time to hospitals, clinics, schools, supermarkets, and fire stations under a 100-year return period flood scenario in Stockholm, Sweden, for both

Purpose: Right ventricular (RV) dysfunction is the key prognostic factor in pulmonary arterial hypertension (PAH). Progression to RV failure involves dilatation, systolic and diastolic impairment, fibrosis, and metabolic changes. Lung transplantation (LTx) normalizes RV afterload, but the extent of recovery and its relation to immunosuppressive therapy remain unclear. We aimed to assess RV functio

Background: Cardiac allograft vasculopathy (CAV) is one of the major long-term complications in patients after heart transplantation (HTx) limiting allograft function and longevity. CAV can be studied non-invasively by evaluating myocardial perfusion (MP). Aspirin is re--ed after Htx, but it is unclear whether it affects the development of CAV. The aim of this study was to investigate the associat

Objective A common threonine481serine polymorphism (T481S) has been shown in vitro to strongly activate the chloride channel Kb (CLC-Kb) expressed in the kidney, and the 481S allele has been associated with human hypertension. The study aim was to evaluate the association of the T481 S polymorphism with blood pressure (BP) levels and the BP progression rate in Swedes. Design and methods The cardio

Smooth muscle cell (SMC)-specific deletion of transforming growth factor beta (TGF-beta) signaling would help elucidate the mechanisms through which TGF-beta signaling contributes to vascular development and disease. We attempted to generate mice with SMC-specific deletion of TGF-beta signaling by mating mice with a conditional ("floxed") allele for the type 11 TGF-beta receptor (tgfbr2(flox)) to

A method to study total deposition of aerosol attached radon progeny in children and adults have been validated and used in home environments. Two persons, one child and one adult are tested simultaneously, thus inhaling from the same aerosol and allowing for a direct comparison. The aim of the study was to increase the knowledge of the lung deposition and thereby the knowledge of the radiation do

BACKGROUND: The transport of large proteins across the glomerular capillary wall (GCW) may increase several fold in glomerular diseases. The occurrence of IgM in urine is a consequence of the presence of large defects or shunts in the GCW, whereas albuminuria is probably a result of an altered charge- and size-selectivity of the GCW. In order to examine whether patho-morphological differences infl

Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females perfo

Objective The effect of salt restriction on blood pressure is under intense debate. We tested the effect of 100 mmol salt reduction on ambulatory blood pressure (ABP) in 46 Swedish individuals, 39 of whom completed the study, using a double-blind, placebo-controlled, crossover design. Furthermore, we tested whether the basal plasma concentration of renin or N-terminal atrial natriuretic peptide (N

Endoglucanases (EGI) (endo-1,4-β-d-glucan-4-glucanohydrolase, EC 3.2.1.4, Cel7B) of Trichoderma reesei are industrially important enzymes. Thus, there is a great need for development of a primary recovery method suitable for large-scale utilization. In this study we present a concept applicable for large-scale purification of an EGI fusion protein by one-step extraction in a poly(ethylene glycol)

Quadrivalent human papillomavirus (HPV) vaccine has been shown to provide protection from HPV 6/11/16/18-related cervical, vaginal, and vulvar disease through 3 years. We provide an update on the efficacy of the quadrivalent HPV vaccine against high-grade cervical, vaginal, and vulvar lesions based on end-of-study data from three clinical trials. Additionally, we stratify vaccine efficacy by sever

Direct electron transfer (DET) reactions of recombinant tobacco peroxidase (rTOP), namely direct electroreduction of Compound I/ Compound II and heme Fe3+/2+ conversion, were studied on gold electrodes. rTOP of wild type, non-glycosylated, was produced using, an Escherichia coli expression system. At pH 5.0, the redox potential for direct electrochemical transformation of the Fe3+/2+ of the peroxi

Aims: To genetically sub-type Campylobacter jejuni strains isolated from migratory birds, and to compare these with clinical strains collected in the same area and corresponding time period, with the aim to increase our knowledge on sub-types occurring among wild birds and their possible impact on human disease. Methods and Results: We sub-typed C. jejuni strains from migrating birds (n = 89) and

The apolipoprotein (apoE) epsilon4 allele was studied in fronto-temporal dementia (FTD), a diagnostic category including the specific disorders Pick's disease and frontal lobe degeneration of non-Alzheimer type (FLD). These dementing diseases have neuronal and synaptic degeneration in common with Alzheimer's disease (AD), for which the presence of the apoE epsilon4 allele is a known risk factor, a

OBJECTIVE: To determine if beneficial effects of a weight-management program could be sustained for up to 24 months in a randomized trial in an ethnically diverse obese population. PATIENTS AND METHODS: There were 209 obese children (BMI > 95th percentile), ages 8 to 16 of mixed ethnic backgrounds randomly assigned to the intensive lifestyle intervention or clinic control group. The control group

Many studies have found close relationships between accessibility and various socio-economic indicators. Yet, since accessibility tends to have differentiated effects, both socially and spatially, there is a need for a model which allows for a disaggregated analysis of accessibility. The model should be possible to use in areas where road network data is incomplete. In this paper such an accessibi

OBJECTIVES: To investigate whether the interleukin-1 receptor antagonist (Il-1ra) and interleukin-1beta (Il-1beta) can be detected in human carotid artery tissue, and whether their presence is related to evidence of Chlamydia pneumoniae infection, risk factors for atherosclerosis, and clinical data. SETTING: Departments of Vascular Diseases and Surgical Pathophysiology, University Hospital, Malmö,
