During co-incubation of human inter-alpha-inhibitor (IalphaI) and human tumor necrosis factor-stimulated gene 6 protein (TSG-6) SDS-stable interactions are formed between the two proteins. We have analyzed the products of this reaction and characterized the mechanism of complex formation. Following the incubation seven new bands not previously identified were apparent in SDS-PAGE. Three of these b
A palaeomagnetic study of samples from dykes in the Protogine Zone (PZ) south of Lake Vattern has yielded two characteristic magnetic components, A and B. A comparison with previous data and the Sveconorwegian Loop of the Fennoscandian Apparent Polar Wander Path (APWP) make it possible to estimate the age of the corresponding palaeomagnetic poles. They are situated close to the "Loop", which indic
It is well established that fibroblasts play a crucial role in pathophysiological extracellular matrix remodelling. The aim of this project is to elucidate their role in normal physiological remodelling. Specifically, the remodelling of the human cervix during pregnancy, resulting in an enabled passage of the child, is used as the model system. Fibroblast cultures were established from cervices of
The aim of the present study was to investigate whether current smoking, ex-smoking, or amount of current smoking among postmenopausal women was associated with plasma levels of testosterone, and rostenedione, and DHEAs. About 65,000 women in Sweden have participated in two population-based prospective cohort studies where blood samples were collected at baseline, and information on life-style, re
We compare Forward Error Correction (FEC) and frame AC-Cumulation (ACC) to see which of the two schemes most effectively reduce frame loss rate for an aggregate of VoIP flows, sharing a network bottleneck. We model this bottleneck by a M/M/1/K queue and we analytically show that given certain assumptions, FEC is the best choice for low initial load at the bottleneck. Then, as the initial load incr
In an attempt to elucidate the effect of mixing on the rate and extent of enzymatic hydrolysis of cellulosic substrates, alpha -cellulose was hydrolysed using a commercial cellulase preparation at varying levels of substrate concentration (2.5,5 and 7.5% (w/v)) and by using three shaking regimes: continuous at low-speed (25 rpm), continuous at high-speed (150 rpm) and an intermittent regime compri
OBJECTIVE: In acute respiratory distress syndrome, the relationships between changes in the elastic behavior of the respiratory system and biological markers of extra-cellular matrix or surfactant turn-over could give some insights into its pathophysiological determinants. DESIGN AND MEASUREMENTS: In 17 patients with acute respiratory distress syndrome, we assessed the relationship between chord c
Time-resolved and spatially resolved measurements of the diffuse reflectance from biological tissue are two well-established techniques for extracting the reduced scattering and absorption coefficients. We have performed a comparison study of the performance of a spatially resolved and a time-resolved instrument at wavelengths 660 and 785 nm and also of an integrating-sphere setup at 550-800 nm. T
Important characters in the classification of the lichenized familyAlectoriaceae (Lecanorales) are discussed and evaluated. A few associated genera presently accommodated in the familyParmeliaceae (Lecanorales) are also discussed. Characters in the asci and hamathecium are of major importance, but structural characters such as general thallus organization and anatomy of cortical layers must also b
In this study the aim was, through interviews, to disclose 13 nurses' personal knowledge about the patients, themselves, and care provision, using a phenomenological-hermeneutic analysing method. Caring for people with severe dementia meant an intertwined life world emanating from making and doing together and the delicate interpretative work that the care provision required. The intertwined life
This paper examines current perceptions within international aid agencies regarding the existing and potential roles of housing and urban development planning as a tool for reducing urban disaster risk in developing countries. It is mainly based on interviews with more than 50 professionals from international agencies and a review of documents on planning and risk reduction. The paper analyses t
A new particulate magnetic resonance (MR) contrast agent was prepared by controlled precipitation of iron oxide in an aqueous starch solution. The potential of the magnetic starch microspheres (MSM) as a hepatosplenic contrast enhancer was studied by MR spectroscopy and MR imaging. Intravascular administration of MSM to rodents showed an effective blood clearance and a tissue-specific localization
The purpose of this study was to investigate the relationship between student influence, students' strategic approaches to studying and academic achievement, and to examine differences between students in a Master's programme in Engineering with conventional teaching and one based on problem-based learning in a sample of 268 students. A version of the Approaches and Study Skills Inventory for Stud
The impact of the optical properties on the annual performance of flat plate collectors in a Swedish climate has been estimated with the MINSUN program. The collector parameters were determined with a theoretically based calculation program verified from laboratory measurements. The importance of changes in solar absorptance and thermal emittance of the absorber, the addition of a teflon film or a
A high-spin rotational cascade of six gamma rays has been observed in Zn-62. The quadrupole moment of 2.7(-0.5)(+0.7) e b measured for this band corresponds to a deformation beta(2) = 0.45(-0.07)(+0.10). The properties of this band are in excellent agreement with calculations that predict high-spin superdeformed bands in Zn-62 with deformations beta(2) = 0.41-0.49. These results establish a new re
Background: This study examined the natural course of patients following surgery for small bowel obstruction (SBO) caused by abdominal adhesions. In addition, a cost analysis was performed. Methods: A retrospective analysis was undertaken of 102 patients who underwent surgery between 1987 and 1992 for intestinal obstruction due to abdominal adhesions. Results: Median follow-up was 14 years. The 10
Mass, heat and momentum transport processes are coupled with catalytic chemical reactions in a methane steam reforming duct. it is often found that endothermic and exothermic reactions in the ducts are strongly integrated by heat transfer from adjacent catalytic combustion ducts. In this paper, a three-dimensional calculation method is developed to simulate and analyze reforming reactions of metha
