Progression to hormone-refractory growth of prostate cancer has been suggested to be mediated by androgen receptor (AR) gene alterations. We analyzed AR for mutations and amplifications in 21 locally recurrent prostate carcinomas treated with orchiectomy, estrogens, or a combination of orchiectomy and estramustine phosphate using fluorescence in situ hybridization, single-strand conformation polym
PURPOSE: To in a cross-sectional study population investigate concentrations of cartilage and bone markers, and pro-inflammatory cytokines in synovial fluid (SF) collected at different time-points from acutely injured knees with hemarthrosis and to compare these with SF concentrations of knees of age and gender-matched healthy reference subjects. METHODS: SF was aspirated from the acutely inju
Purpose - The purpose of this paper is to further build up the knowledge about reasons for small and mid-sized enterprises (SMEs) to adopt open source enterprise resource planning (ERP) systems. Design/methodology/approach - The paper presents and analyses findings in articles about proprietary ERPs and open source ERPs. In addition, a limited investigation of the distribution channel SourceForge
Review of Øystein Ekroll, “Med kleber og kalk. Norsk steinbyggig i mellomalderen 1050-1550" (Oslo 1997).
Background: An important aspect of physiotherapy professional autonomy is the ethical code of the profession, both collectively and for the individual member of the profession. The aim of this study is to explore and add additional insight into the nature and scope of ethical issues as they are understood and experienced by Danish physiotherapists in outpatient, private practice. Methods: A qu
PURPOSE:: To describe riboflavin and ultraviolet light (UV) collagen crosslinking as an effective treatment for infectious keratitis. METHODS:: A 25-year-old previously healthy female contact lens user was diagnosed with unilateral severe keratitis with unclear pathogenesis, although the clinical presentation suggested acanthamoeba as the infectious agent. A 4-mm diameter, annular, semi-opaque inf
BACKGROUND: Staurosporine is a therapeutic agent that inhibits tumor cell growth by inducing cell death via intrinsic apoptotic pathways. Our previous studies in clinical settings have suggested that certain subpopulations of patients with acute myeloid leukemia (AML) had poor response to chemotherapy. MATERIALS AND METHODS: The effect of staurosporine on apoptosis and cell cycle distribution in h
Introduction: Although numerous tumour markers are available for periampullary tumours, including pancreatic cancer, their specificity and sensitivity have been questioned.Materials and methods: To assess the diagnostic and prognostic values of tissue polypeptide specific antigen (TPS), carbohydrate antigen 19-9 (CA 19-9), vascular endothelial growth factor (VEGF-A), and carcinoembryonic antigen (
Phosphorylated tyrosine residues in receptor tyrosine kinases serve as binding sites for signal transduction molecules. We have identified two autophosphorylation sites, Tyr-988 and Tyr-1018, in the platelet-derived growth factor (PDGF) alpha-receptor carboxyl-terminal tail, which are involved in binding of phospholipase C-gamma (PLC-gamma). The capacities of the Y988F and Y1018F mutant PDGF alpha
Time-resolved x-ray diffraction with picosecond temporal resolution is used to observe scattering from impulsively generated coherent acoustic phonons in laser-excited InSb crystals. The observed frequencies and damping rates are in agreement with a model based on dynamical diffraction theory coupled to analytic solutions for the laser-induced strain profile. The results are consistent with a 12 p
PURPOSE: It is unknown whether childhood cancer and its treatment are associated with sperm DNA damage, which subsequently affects fertility and might be transmitted to the offspring. The aim of this study was to assess DNA fragmentation index (DFI) as an indicator of sperm DNA integrity in childhood cancer survivors (CCS), treatment regimen taken into account.EXPERIMENTAL DESIGN: In 99 CCS and 19
Concurrent testing of the cores in a core-based system- on-chip reduces the test application time but increases the test power consumption. Power models, test architecture design, and scheduling algorithms have been proposed to schedule the tests as concurrently as possible while respecting the power budget. The commonly used global peak power model, with a single value capturing the power dissipa
Background:No large cohort study has examined the risk of endometrial cancer in relation to sun exposure.Methods:A population-based cohort study of 29 508 women who answered a questionnaire in 1990-92, of whom 24 098 responded to a follow-up enquiry in 2000-02. They were followed for an average of 15.5 years.Results:Among the 17 822 postmenopausal women included, 166 cases of endometrial cancer we
Anecdotal evidence suggests that task-shifting or the redistribution of responsibilities from fully-trained surgeons to clinicians with fewer qualifications could become a major component of surgical care delivery in many low-income and middle-income countries (LMICs). Our goal was to summarise the scope of surgical task-shifting in LMICs through a systematic review of the medical literature.
Traumatic brain injury (TBI) is an important health problem, and a leading cause of death in children worldwide. Mitochondrial dysfunction is a critical component of the secondary TBI cascades. The response of mitochondria in the pediatric brain to injury has limited investigation, despite evidence that developing brain's response differs from the adult, especially in diffuse non-impact TBI. We pe
