In the Swedish Knee Arthroplasty Study, all 699 Oxford meniscal bearing cemented unicompartmental prostheses (Biomet, Bridgend, UK) were identified and analyzed regarding failure pattern and compared with all Marmor prostheses (Smith & Nephew Richards, Orthez, France) and with a time-, age-, and sex-matched subset of Marmor prostheses using survival statistics expressed as cumulative revision
M1 aminopeptidases comprise a large family of biologically important zinc enzymes. We show that peptide turnover by the M1 prototype, leukotriene A4 hydrolase/aminopeptidase, involves a shift in substrate position associated with exchange of zinc coordinating groups, while maintaining the overall coordination geometry. The transition state is stabilized by residues conserved among M1 members and i
Children with acute lymphoblastic leukemia (ALL) have been shown to develop changes on computed tomography (CT) scans of the brain. These changes are seen both during and after therapy. Some of the results have been contradictory. Nine children with ALL were examined by CT of the brain during induction therapy. All children showed normal CT scans on the day of diagnosis. One month later all had di
A new type of liposomal liver-specific contrast medium was studied in an experimental tumour model. Rabbits were inoculated with VX2-carcinoma directly in the liver of laparotomy. CT studies were carried out 14 days after inoculation. The liver-specific contrast medium consisted of a suspension of liposomes in a 100 mg I/ml iodixanol solution, with equal amounts of encapsulated and nonencapsulated
Complement, which bridges innate and adaptive immune responses as well as Immoral and cell-mediated immunity, is antiviral. Kaposi's sarcoma-associated herpesvirus (KSHV) encodes a lytic cycle protein called KSHV complement control protein (KCP) that inhibits activation of the complement cascade. It does so by regulating C3 convertases, accelerating their decay, and acting as a cofactor for factor
A Swedish translation of the Barrow Neurological Institute Screen for Higher Cerebral Functions was administered to 52 normal control subjects and 36 patients with well-documented brain dysfunction. Findings replicated those reported in American samples. Level of performance was strikingly similar between Swedish controls and American controls, especially in individuals between 15 and 39 years. Sw
We have previously shown that porcine aortic endothelial cells expressing the Y934F platelet-derived growth factor (PDGF) beta-receptor mutant respond to PDGF-BB in a chemotaxis assay at about 100-fold lower concentration than do wild-type PDGF beta-receptor-expressing cells (Hansen, K., Johnell, M., Siegbahn, A. , Rorsman, C., Engstrom, U., Wernstedt, C., Heldin, C.-H., and Ronnstrand, L. (1996)
When a society plans the upbringing and education of its members, irrespective of age and level, one absolute requirement must be that it develops their ability of self-determination. A psycho-ecological approach to a study of the individual’s self-cognition (perception and evaluation) and self-determination (i.e. development of plans of action) focuses on the mutual relations existing between the
The aim of this study was to evaluate the ability of intravascular ultrasound to diagnose tumor involvement of the portal and the superior mesenteric veins using the preoperative percutaneous, transhepatic approach, and to compare the findings with those made at concomitant direct portography, surgery, and histopathological examination. Ten patients with a preoperative diagnosis of a resectable tu
The inflammatory mediator leukotriene B(4) (LTB(4)) binds to and activates a G-protein-coupled receptor named BLT(1). We have previously produced two monoclonal antibodies, named 7B1 and 14F11, that bind specifically to this receptor. Using a HeLa cell line expressing human BLT(1), we find that both antibodies inhibit LTB(4)-induced calcium release, and activation of a MAP-kinase-sensitive lucifer
This study was aimed at investigating the psychometric properties of the Interview Schedule for Social Interaction (ISSI), in terms of construct and discriminant validity and unidimensionality, in three psychiatric samples with varying prerequisites for social interaction: 1) an outpatient sample of working age with mixed diagnoses, 2) an outpatient sample with schizophrenia, and 3) an inpatient s
Arsenic enrichment of groundwater in the Red River (Song Hong) delta in Vietnam was discovered in 1998. Several studies performed in this area found concentrations of As exceeding the WHO-guideline of 10 lg/L. This study focuses on an area south of Hanoi city, Nam Du, where a new well field came into operation in 2004. The new well field is situated on the bank along the Red River in order to faci
Previous studies suggested a link between the use of G-CSF and increased incidence of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) after immunosuppressive therapy (IST) for severe aplastic anemia (SAA). This European survey included 840 patients who received a first-line IST with (43%) or without (57%) G-CSF. The incidences of MDS/AML in patients who did or did not receive G-CSF
Aim: Negative Pressure Wound Therapy (NPWT) has become widely adopted over the last 15 years and over 1000 peer-reviewed publications are available describing its use. Despite this, there remains uncertainty regarding several aspects of usage. In order to respond to this gap a global expert panel was convened to develop evidence-based recommendations describing the use of NPWT. In this communicati
