OBJECTIVE: To study the variation of HCV 5'-NCR and core gene in serial sera collected from patients with HCV infection. METHODS: Serial sera were collected from 4 plasma-donors with HCV infection. 5'-NCR and core gene were amplified, sequenced and analyzed using software. RESULTS: All the sequences obtained from the serial sera of patients with HCV infection were 1b and 2a subtypes. The variation

Surgery for Hirschsprung's disease is often complicated by post-operative bowel motility disorders. The impact of intestinal neural histology on the surgical outcome has been previously studied, but no information is available concerning the influence of the distribution of interstitial cells of Cajal (ICC) on these complications. These cells are considered to be pacemakers in the gastrointestinal

The finite element method is applied to solve coupled steady-state fluid flow and heat transfer problems in insulated pipes of district heating networks. The main advantage of the finite element method involved here is the standard discretization and solution technique for both coupling of temperature-dependent physical properties in the thermo-hydraulic flow and for description of the multilayere

OBJECTIVE: To study the temporal relation between vascular inflammatory activity and synovial hyperplasia during the development of methylated bovine serum albumin (mBSA) antigen induced arthritis (AIA) in the rat, and to correlate these variables to changes in knee diameter. The influence of a single dose of indomethacin and methotrexate (MTX) on these measures was also determined. METHODS: Vascu

Kinetic measurements at low temperatures (310-360 K) using gas chromatography (GC) for benzene hydrogenation on Pt(100) and Pt(111) single crystal surfaces have been carried out at Torr pressures. These kinetic measurements demonstrated a linear compensation effect for the production of cyclohexane. A detailed application of the model of selective energy transfer to the experimentally obtained res

Both members of the diploid-tetraploid species pair Anthericum ramosum L. and Anthericum liliago L. occur as geographically disjunct isolates on the margins of their northern range in Scandinavia. Variation in floral morphology was studied in 33 populations of A. ramosum from four geographic regions and 25 populations of A. liliago from seven regions in Scandinavia. Tepal shape was characterized w

A few tens of millions of years after the intrusion of the Early Svecofennian (similar to1.87-1.85 Ma) granitoids in central Sweden, a renewed magmatic activity resulted in the emplacement of the Late Svecofennian granites, the tectonic setting of which remains obscure. S-type granites dominate this group, but both I-type and transitional granites are common. This study deals with one of these int

BACKGROUND: Although the true benefits and disadvantages of prostate cancer screening are still not known, the analysis of fatal cases is important for increasing knowledge of the effects of prostate cancer screening on mortality. Who dies from prostate cancer despite participation in a population-based prostate-specific antigen (PSA) screening program? METHODS: From the Goteborg branch of the Eur

A diffusion flame of dimethyl ether (DME) and air in a counterflow burner has been investigated experimentally by means of different laser-based methods. Quantitative measurements of temperature, O-2 concentration, and OH concentration have been carried out using dual broadband rotational coherent anti-Stokes Raman Spectroscopy (CARS), Rayleigh scattering and laser-induced fluorescence (LIF). Furt

Transvaginal ultrasound plays a pivotal role in the management of non-pregnant women with abnormal vaginal bleeding. No other imaging technique has a role in the triage of these women. In women with postmenopausal bleeding, ultrasound is used to categorise women as at low or high risk of endometrial cancer, and the result of the ultrasound examination is the basis for further management. In women

People with mobility disability are more often overweight or obese and have lower social capital than people without mobility disability. It is unclear whether having a combination of mobility disability and overweight or obesity furthers negative development of social capital over time.

Alterations in cell cycle pathways and retinoic acid signaling are implicated in leukemogenesis. However, little is known about the roles of cyclin-dependent kinases (CDKs) in treatment response of leukemia. In this study, we observed that CDK1 expression was significantly higher in bone marrow from 42 patients with acute myeloid leukemia (AML) at recurrence than that at first diagnosis (p = 0.04)

Introduction: Breast cancer is a profoundly heterogeneous disease with respect to biologic and clinical behavior. Gene-expression profiling has been used to dissect this complexity and to stratify tumors into intrinsic gene-expression subtypes, associated with distinct biology, patient outcome, and genomic alterations. Additionally, breast tumors occurring in individuals with germline BRCA1 or BRC

Phenotypic variability is well recognized in severe hemophilia A. A few studies, mainly in adults treated lifelong on demand, suggest that bleeding phenotype correlates with factor VIII gene (F8) mutation type. Because treatment regimens influence outcomes to a large extent, examining bleeding phenotype during the first years of life may be the most suitable way to define this variability. We set

The addition of crop residues is a common farming practice to increase the organic carbon content of agricultural soils with particular importance in organically managed crops. Residues can be added either from the crop plant itself or from other plants and the type of litter may differentially affect decomposer populations. Effects of litter addition may cascade up to affect generalist predators

Bengt Johannisson received the International Award for Entrepreneurship and Small Business Research in 2008. In this essay we present and evaluate his work over the last four decades in three of its dimensions: pioneering, provocative and participative. While his research interests and themes range widely, early on he resisted the individualization of entrepreneurship studies and instead emphasize
