Lactobacillus reuteri is known to produce exopolysaccharides (EPS), which have the potential to be used as an alternative biothickener in the food industry. In this study, the effect of several environmental conditions on the growth and EPS production in the L. reuteri strain ATCC 55730 was determined. The expression of the corresponding reuteransucrase gene, gtfO, was investigated over time and t
The modernisation of Swedish households during the twentieth century prompted a considerable productivity growth in household production. This paper examines the association between this process and the allocation of female time in Swedish urban households during the period 1920-1990. Estimates presented in the paper suggest a minimum potential time reduction for a fixed volume of routine househol
We demonstrate a novel non-intrusive technique based on tunable diode laser absorption spectroscopy to investigate human maxillary sinuses in vivo. The technique relies on the fact that free gases have much sharper absorption features (typical a few GHz) than the surrounding tissue. Molecular oxygen was detected at 760 nm. Volunteers have been investigated by injecting near-infrared light fibre-op
Randomized clinical trials have established the role of third-generation aromatase inhibitors (AIs) (letrozole, anastrozole, and exemestane) as standard treatment for patients with hormone-sensitive metastatic breast cancer who have experienced disease progression with antiestrogen therapy. Significant gains in clinical efficacy and improved tolerability over progestins (megestrol acetate) and the
Rats housed in an enriched environment allowing both social interaction and physical activity improve more than rats housed in standard laboratory cages after focal brain ischemia. To determine the relative importance of social and physical activity, rats that sustained ligation of the middle cerebral artery were kept in an enriched environment with opportunities for various activities (group A),
Vacuum-assisted wound closure (VAC®) therapy is considered to be superior to conventional dressings in the treatment of peri-vascular groin infections after vascular surgery at our department. Therefore, we wanted to perform an early interim analysis of clinical outcome in these seriously ill patients at risk for amputation and death. Patients were randomised to either VAC® (n = 5) or Sorbalgon® (
Objective: To update evidence for available therapies in the treatment of hip and knee osteoarthritis (OA) and to examine whether research evidence has changed from 31 January 2006 to 31 January 2009. Methods: A systematic literature search was undertaken using MEDLINE, EMBASE, CINAHL, AMED, Science Citation Index and the Cochrane Library. The quality of studies was assessed. Effect sizes (ESs) an
Pulmonary infection is a common complication after lung transplantation, and early detection is crucial for outcome. However, the condition can be clinically difficult to diagnose and to distinguish from rejection. The aim of this prospective study was to evaluate heparin-binding protein (HBP), lysozyme, and the cytokines interleukin (IL)-1β, IL-6, IL-8, IL-10 and tumor necrosis factor (TNF) in br
A challenge in perishable food industry today is variable and unknown food quality caused by different temperature conditions. This sometimes leads to unreliable printed shelf lives (best before dates) and food waste. Hence, temperature monitoring and control along cold food supply chains (FSCs) are essential for maintaining food quality and safety of perishable food products. This paper evaluates
The use of fetal bovine serum hinders obtaining reproducible experimental results and should also be removed in hormone and growth factor studies. In particular hormones found in FBS act globally on cancer cell physiology and influence transcriptome and metabolome. The aim of our study was to develop a renal carcinoma serum free culture model optimized for (embryonal) renal cells in order to selec
Haemophilia A and B diagnosis and disease severity classification are determined on the basis of results from factor VIII (FVIII) and factor FIX (FIX) activity assays, respectively. These assays are also used for potency labelling, postinfusion monitoring of factor replacement products and testing for FVIII/FIX inhibitors. This review focuses on activated partial thromboplastin time (APTT)-based o
The inhibition of unproductive motor movements is regarded as a fundamental cognitive mechanism. Recently it has been shown that species with large absolute brain size or high numbers of pallial neurons, like great apes and corvids, show the highest performance on a task purportedly measuring this mechanism: the cylinder task. In this task the subject must detour a perpendicularly oriented transpa
Organisms that regularly encounter stressful environments are expected to use cues to develop an appropriate phenotype. Water fleas (Daphnia spp.) are exposed to toxic cyanobacteria during seasonal algal blooms, which reduce growth and reproductive investment. Because generation time is typically shorter than the exposure to cyanobacteria, maternal effects provide information about the local condi
Hemoglobin (Hb)-based oxygen carriers (HBOC) are modified extracellular proteins, designed to replace or augment the oxygen-carrying capacity of erythrocytes. However, clinical results have generally been disappointing due to adverse side effects, in part linked to the intrinsic oxidative toxicity of Hb. Previously a redox-active tyrosine residue was engineered into the Hb β subunit (βF41Y) to fac
Using classical design methods for tillage machines does not completely guarantee a safety and satisfactory performance, due in part to the randomness of tillage forces. This randomness is derived from the variability in soil engineering properties and the variations in tool design parameters and operational conditions. In this paper, a reliability-based design approach was developed, for the firs
Birds migrating between distant locations regularly perform long continuous flights lasting several days. What compass mechanism they use is still a mystery. Here, we use a novel approach, applying an individual-based model, taking compass mechanisms based on celestial and geomagnetic information and wind into account simultaneously, to investigate what compass mechanism likely is used during long
The Bridge is a television drama that is suggestive of the significance of place in understanding international formats. The specificity of place is built into the storytelling, as the format is located in the geo-cultural politics of border territories in three versions of the drama series set between Sweden and Denmark, Britain and France, and USA and Mexico (Filmlance International and Shine Gr
The thesis contains three papers that comprise studies of the dynamic behaviour of involute spur and helical gears, and one paper that describes a method to determine the influence of misalignment on the static helical gear tooth stress. In the first study, the influence of the contact ratio on the dynamic response of a spur gear was examined. The spur gear pair was modelled using a single degree
