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
In this work, we present a ridged, microfabricated, force sensor that can be used to investigate mechanical interactions between cells exhibiting contact guidance and the underlying cell culture substrate, and a proof-of-function evaluation of the force sensor performance. The substrates contain arrays of vertical pillars between solid ridges that were microfabricated in silicon wafers using photo
We show that the boundary conditions entering in the definition of the self-adjoint operator Delta(A,B) describing the Laplacian plus afinite number of point interactions are local if and only if the corresponding wave equation phi = Delta(A,B)phi has finite speed of propagation.
Multiconfiguration Hartree-Fock (MCHF) calculations of hyperfine constants for the 2s2p 3P states of beryllium and the ground states of boron and carbon are reported. The capacity of a recently developed configuration-interaction program [Froese Fischer and Tong (unpublished); Stathopoulos and Froese Fischer (unpublished)], allowing for large configuration expansions, is explored. Using a systemat
Between 1999 and 2005, 10 264 patients who had undergone total hip replacement (THR) for subcapital fracture of the hip were compared with 76 520 in whom THR had been performed for other reasons. All the cases were identified through the Swedish Hip Arthroplasty Register. The THRs performed as primary treatment for fracture were also compared with those done after failure of internal fixation. Aft
Proteome analysis involves many steps that generate large quantities of data in different formats. This creates a need for automatic data merging and extraction of important features from data. Furthermore, metadata need to be collected and reported to enable critical evaluation of results. Many data analysis tools are developed locally in research laboratories and are nontrivial to adapt for othe
BACKGROUND: Several surveys show that patients with chronic heart failure (CHF) are sub-optimally managed and treatment guidelines are not implemented in clinical practice. AIMS: To investigate awareness and perceptions of the 2005 European Society of Cardiology (ESC) guidelines for CHF. METHODS: 467 cardiologists from seven European countries completed an on-line interview using a validated, semi
Close to 50 genetic loci have been associated with type 2 diabetes (T2D), but they explain only 15% of the heritability. In an attempt to identify additional T2D genes, we analyzed global gene expression in human islets from 63 donors. Using 48 genes located near T2D risk variants, we identified gene coexpression and protein-protein interaction networks that were strongly associated with islet ins
As breast volume may be associated with heart cancer risk, we studied the relationship between breast volume, CYP1A2*1F and coffee intake. Among healthy premenopausal non-hormone users, 3+ cups per day was associated with lower volume only in C-allele carriers (P(interaction)=0.02), which is consistent with reports that coffee protects only C-allele carriers against breast cancer.British Journal o
Dermatan sulfate is a highly sulfated polysaccharide and has a variety of biological functions in development and disease. Iduronic acid domains in dermatan sulfate, which are formed by the action of two DS-epimerases, have a key role in mediating these functions. We have identified the catalytic site and three putative catalytic residues in DS-epimerase 1, His205, Tyr261 and His450, by tertiary s
A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test
Background People applying for a housing adaptation (HA) grant are at great risk of participation restrictions due to declining capacity and environmental barriers. Aim To investigate the association of person-, environment-, and activity-related factors with participation frequency and satisfaction among people applying for a housing adaptation grant. Material and methods Baseline cross-sectional
BACKGROUND:: Few and inconclusive results have been presented regarding the influence of human T-lymphotropic virus 1 (HTLV-1) infection on the risk of acquiring tuberculosis (TB). METHODS:: In 1994-1997, we performed a prospective study on hospitalized adult patients with pulmonary TB in Guinea-Bissau and compared the clinical outcome in HIV-2 and HIV-negative patients. We determined the prevalen
The main purpose of this study was to investigate whether the outcome obtained at the end of a work rehabilitation programme for people with various disabilities were stable in a one-year perspective. An additional aim was to explore which factors influenced the outcome upon completion of work rehabilitation and at the one-year follow-up. The study used information from a database and comprised 29
The aim of this study was to validate the Edholm scale (Edholm, 1966) and the ISO 8996 standard (International Organization for Standardization [ISO], 1990) by comparing the metabolic rates estimated for both methods with the actual measured metabolic rate (MMeas) in 6 manual material handling tasks simulated under laboratory conditions. The metabolic rate was calculated from oxygen consumption VO
Objective: Compare perioperative course and long-term mortality after liver resection for colorectal cancer (CRC) metastases between patients who had preoperative treatment with portal vein embolization (PVE) and chemotherapy or chemotherapy alone. Methods: Among patients undergoing liver resection for CRC metastases following preoperative chemotherapy treatment, 17 patients who had received pre
