Objective. The aim of this study was to evaluate enterocystometry, voiding pattern and urine leakage of four types of orthotopic bladder substitute. Material and methods. At eight urological departments, 78 consecutive men were studied: 66 with an ileal neobladder [30 Studer pouches (S), 24 Hautmann pouches (H) and 12 T-pouches (T)] and 12 with a right colonic [Goldwasser type (G)] neobladder. Ent
Background: Women with germline BRCA1 or BRCA2 (BRCA1/BRCA2) mutations are at very high risk of developing breast cancer, including asynchronous contralateral breast cancer (CBC). BRCA1/BRCA2 genes help maintain genome stability and assist in DNA repair. We examined whether the risk of CBC associated with radiation treatment was higher among women with germline BRCA1/BRCA2 mutations than among non
Low levels of vitamin D may play a role in psychiatric disorders, as cross-sectional studies show an association between vitamin D deficiency and depression, schizophrenia and psychotic symptoms. The underlying mechanisms are not well understood, although vitamin D is known to influence the immune system to promote a T helper (Th)-2 phenotype. At the same time, increased inflammation might be of i
Folding of the ribosomal protein S6 is a malleable process controlled by two competing, and partly overlapping, folding nuclei. Together, these nuclei extend over most of the S6 structure, except the edge strand beta 2, which is consistently missing in the folding transition states; despite being part of the S6 four-stranded sheet, beta 2 seems not to be part of the cooperative unit of the protein
Aims: The NAB2-STAT6 fusion was recently identified as a consistent finding in solitary fibrous tumour (SFT), resulting in nuclear expression of the C-terminal part of STAT6. Gene expression studies of SFT revealed high expression of the GRIA2 gene. The aim of this study was to examine GRIA2 expression in SFTs and other soft tissue tumours to evaluate its diagnostic utility. Methods and results: I
P>1. Sex ratios in unisexual bryophytes are most often female biased, whereas male-biased sex ratios predominate in unisexual seed plants. This 'bryophyte paradox', i.e. that sex ratios are biased in favour of the sex associated with the highest reproductive costs, has remained unexplained. 2. Analysis of sex-ratio patterns via the influence of sex distribution on population growth rates (lambda)
BACKGROUND: According to previous studies, foreign travellers and backpackers are at increased risk of sexually transmitted infections (STI). Concurrently, STI incidence, especially Chlamydia, is increasing among young Swedes. Our objective was to investigate Swedish backpackers' own view of sexual health and risks while travelling, with the purpose to identify hypotheses for further, more extensi
Although plesiosaurs and mosasaurs co-existed for about 35 million years at the end of the Cretaceous, the fossil record documenting interactions between these two groups of marine reptiles is meagre. The discovery of deeply incised scars on a limb bone of an immature polycotylid plesiosaur from the latest early Campanian (in the European two-fold division of the Campanian Stage) of the Kristianst
This paper presents a flow that is suitable to estimate energy dissipation of digital standard-cell based designs which are determined to be operated in the sub-threshold regime. The flow is applicable on gate-level netlists, where back-annotated toggle information is used to find the minimum energy operation point, corresponding maximum clock frequency, as well as the dissipated energy per clock
Objective: To develop a working model so that dispensing pharmacists, patients and medical staff can work together to identify, solve and prevent problems associated with discharge prescriptions. Method: A routine was developed for communication between pharmacists, patients and medical staff and for dispensing drugs at the bedside. Hospital medication lists and prescriptions from the pharmacy a
To evaluate the natural history of untreated complete or partial scapholunate (SL) ligament tears associated with displaced distal radius fractures.
Two differently charged polypeptides, α-poly-L-lysine and poly-L-glutamate, have previ- ously been shown to effectively reduce postoperative intraabdominal adhesions. Though α-poly-L-lysine showed toxicity in doses too close to the lowest the-rapeutic dose, the aim in the present study was to investigate the possible antiadhesive effect of another four cationic polypeptides.
Recent climate change predictions suggest altered patterns of winter precipitation across the Arctic. It has been suggested that the presence, timing and quantity of snow all affect microbial activity, thus influencing CO2 production in soil. In this study annual and seasonal emissions of CO2 were estimated in High-Arctic Adventdalen, Svalbard, and sub-Arctic Latnjajaure, Sweden, using a new trace
Self-pressurization in a cylindrical ribbed tank which is partially filled with liquid hydrogen is investigated numerically under different rib spacing-to-height ratios. The Volume of Fluid (VOF) method is employed as well as a phase change model. Appropriate models are incorporated into the Ansys Fluent by the user-defined functions to carry out the computations. The ribbed surface is modeled as
Arctic waders are well known for their impressive long-distance migrations between their high northerly breeding grounds and wintering areas in the Southern hemisphere. Performing such long migrations requires precise orientation mechanisms. We conducted orientation cage experiments with juvenile sharp-tailed sandpipers (Calidris acuminata) to investigate what cues they rely on when departing from
BACKGROUND: Human herpesvirus 6 (HHV-6) is an important cause of fulminant or acute viral myocarditis. However, insufficiency of standard antiviral treatment against HHV-6 is an emerging problem. OBJECTIVES: To describe the case of child with HHV-6 myocarditis who was treated by unloading with a left ventricular assist device and Artesunate. STUDY DESIGN: Case report supported by histological and
A highly thermostable recombinant xylanase from Thermotoga neapolitana was used as a catalyst for single-step synthesis of n-octyl xylobioside and n-octyl xylotrioside from xylan and n-octanol. Effect of xylan concentration, enzyme dose, reaction water content, reaction temperature and initial pH on the yield of these surfactants has been studied. The optimal conditions for n-octyl xylobioside and
The influence on the crack growth behaviour of a short edge crack under fatigue due to different configurations of a nearby located low angle grain boundary is investigated under quasi-static and plane strain conditions. The geometry is modelled by distributed dislocation dipole elements in a boundary element method approach, and the plasticity is described by discrete dislocations, located along
Abstract in Undetermined ABSTRACT. Optical techniques for tissue diagnostics currently are experiencing tremendous growth in biomedical applications, mainly due to their noninvasive, inexpensive, and real-time functionality. Here, we demonstrate a hand-held fiber optic probe instrument based on fluorescence/reflectance spectroscopy for precise tumor delineation. It is mainly aimed for brain tumor
