The phase behavior over the entire concentration range for the system didodecyldimethylammonium bromide (DDAB)-sodium taurodeoxycholate (STDC)-water, at 25 degrees C, has been investigated, with emphasis on the DDAB-rich part. Polarizing microscopy, SAXS, H-2 NMR and H-1 self-diffusion NMR have been used in combination as probing techniques for phase behavior and microstructure. The system forms f
In this study we have investigated whether the carbon isotopic signature differs between different groups and species of marine phytoplankton depending on growth phase, nutrient conditions and salinity. The 15 investigated algal species, representing the Bacillariophyceae, Chlorophyceae, Cryptophyceae, Cyanophyceae, Dinophyceae and Haptophyceae classes were grown in batch monocultures and analysed
Background: Cancer of unknown primary (CUP) is a fatal cancer, accounting for 3-5% of all diagnosed cancers. Finding the primary site is important for therapeutic choices and we believe that the organ which is designated as the cause of death may give clues about the primary site. Methods: A total of 20,570 patients with CUP were identified from the Swedish Family-Cancer Database. Causes of death
Background: Although advances in the treatment of myeloid neoplasms have led to improved patient survival, this improvement has been accompanied by an increased risk of second primary cancer (ie, the risk of another cancer after myeloid neoplasia). We aimed to assess bi-directional associations between myeloid cancers and other cancers—ie, development of second primary cancer in patients who have
Investigations of host preferences in haematophagous insects, including Culicoides biting midges (Diptera: Ceratopogonidae), are critical in order to assess transmission routes of vector-borne diseases. In this study, we collected and morphologically identified 164 blood-engorged Culicoides females caught in both light traps and permanent 12-m high suction traps during 2008-2010 in Sweden. Molecul
Objectives: The aims of this study were to evaluate the community-based prevalence of atrial fibrillation (AF) in a western society using a geographically well-defined population in the northern part of Sweden as a reference and to estimate the proportion of patients eligible for oral anticoagulation (OAC) prophylactic therapy according to the stroke risk indices CHADS(2) and CHA(2) DS(2) -VASc.

Let $\scr H$ denote a Hilbert space consisting of functions analytic on a bounded, open, connected subset $\Omega$ of the complex plane. Given certain natural hypotheses on $\scr H$, the author characterizes the finite-codimensional subspaces of $\scr H$ that are invariant under multiplication by $z$, showing that all such subspaces have the form $(p\scr H)^-$, where $p$ is a polynomial whose zero
This study aimed to compare the duration of protection against exercise-induced bronchoconstriction (EIB) after inhalation of formoterol (Oxis) Turbuhaler with that of terbutaline Turbuhaler and placebo Turbuhaler in asthmatic patients treated regularly with formoterol Turbuhaler 9 microg b.i.d. and inhaled steroids. The study. performed at three centres (Goteborg and Lund, Sweden, and Trondheim,
The aims of this study were to describe which self-care, productivity, and leisure occupations individuals with multiple sclerosis (MS) perceive as difficult to perform on admission to rehabilitation and the individuals' own perception of the importance of, performance of, and satisfaction with these occupations. Whether the reported self-care, productivity, and leisure occupations were related to
Background: It has been suggested that exhaled breath temperature (EBT) is increased in asthmatic subjects. Objectives: Our aim was to investigate EBT in asthmatics compared to healthy controls before and after eucapnic voluntary hyperventilation (EVH) and a methacholine challenge test (MCT). Methods: A total of 26 asthmatics and 29 healthy controls were included. Forced expiratory volume in 1 s (
Two variants of the thermostable beta-glucosidase TnBgl1A (wt and N221S/P342L) from Thermotoga neapolitana were immobilized on acrylic supports (Eupergit (R) C, Eupergit (R) C250L, and cryogel) and evaluated at conditions close to the boiling point of water. Thermo-gravimetric analysis showed the supports to be stable <250 degrees C. Both wt and N221S/P342L were covalently bound to oxirane-groups
Background and purpose As much as one-third of all total hip arthroplasties in patients younger than 60 years may be a consequence of developmental dysplasia of the hip (DDH). Screening and early treatment of neonatal instability of the hip (NIH) reduces the incidence of DDH. We examined the radiographic outcome at 1 year in children undergoing early treatment for NIH. Subjects and methods All chi
Aim: The objective of this study was to describe patients who experienced an out-of-hospital cardiac arrest (OHCA) by age group. Methods: All patients who suffered from an OHCA between 1990 and 2005 and are included in the Swedish Cardiac Arrest Registry (n = 40,503) were classified into the following age groups: neonates, younger than 1 year; young children, between 1 and 4 years; older children,
Background: Data regarding the association between lipoprotein-associated phospholipase A2 (Lp-PLA(2)) level and incidence of cardiovascular (CV) events are conflicting. This prospective urban population-based study explored the relationship between baseline Lp-PLA(2) activity and mass, respectively, levels and incidence of first coronary heart disease (CHD) and ischemic stroke, respectively. Meth
Human galectins have functionally divergent roles, although most of the members of the galectin family bind weakly to the simple disaccharide lactose (Galss1-4Glc). To assess galectin-glycan interactions in more detail, we explored the binding of several important galectins (Gal-1, Gal-2, and Gal-3) on a glycan microarray containing hundreds of structurally diverse glycans. All three galectins exh
Study Objective: To understand young women's experiences of receiving a diagnosis related to diverse sex development.Design: A qualitative narrative analysis of interviews.Setting: Karolinska University Hospital.Participants: Nine women (aged 20-26 years) with complete androgen insensitivity syndrome, XY or XX gonadal dysgenesis.Interventions: Semistructured interviews.Main Outcome Measures: A nar
A multicentre study was performed at four oncology centres in Sweden, in 160 chemotherapy-naive women, primarily with ovarian or endometrial carcinomas. Abdominal surgery preceded chemotherapy in 146 (91%) women, and another 39 (24%) women had a history of radiotherapy. The chemotherapy regimens contained cisplatin (50-100 mg/m2), in combination with a variety of other agents. In Course 1, all pat
Objectives: To determine the intra- and inter-observer agreement of erosions detected and scored with cone-beam computed tomography (CBCT) of bones in the hands and feet, and to compare CBCT with conventional radiography (CR) for assessment of bone erosions in patients with long-standing rheumatoid arthritis (RA). Method: Thirty patients with long-standing RA from the Better Anti-Rheumatic Pharmac
Wastewater sludge represents an important resource for reuse in agriculture. However, potentially harmful pathogens are a main threat in this context. Thus, the aim of this study was to examine the presence of helminth ova and protozoan cysts in dried sewage sludge samples collected from ten wastewater treatment plants (WWTPs) located in eight governorates in Tunisia. Based on morphological criter
