CD47 regulates collagen I-induced cyclooxygenase-2 expression and intestinal epithelial cell migration.

Increased epithelial cell expression of the cyclooxygenase-2 (COX-2) enzyme is a characteristic event of both inflammatory bowel disease and colon cancer. We here report the novel findings that collagen I-induced de novo synthesis of COX-2 in intestinal epithelial cells is inhibited by pertussis toxin (PTX) and by an inhibitory peptide selective for the heterotrimeric G alpha(i3)-protein. These fi

Use of a T cell interferon gamma release assay in the investigation for suspected active tuberculosis in a low prevalence area.

BACKGROUND: In settings with low background prevalence of tuberculosis (TB) infection, interferon-gamma release assays (IGRA) could be useful for diagnosing active TB. This study aims to evaluate the performance of QuantiFERON-TB Gold (QFT-G) in the investigation for suspected active TB, with particular attention to patients originating in high-incidence countries. Furthermore, factors associated

HAMLET Treatment Delays Bladder Cancer Development.

PURPOSE: HAMLET is a protein-lipid complex that kills different types of cancer cells. Recently we observed a rapid reduction in human bladder cancer size after intravesical HAMLET treatment. In this study we evaluated the therapeutic effect of HAMLET in the mouse MB49 bladder carcinoma model. MATERIALS AND METHODS: Bladder tumors were established by intravesical injection of MB49 cells into poly

Distinct roles for laminin globular domains in laminin alpha1 chain mediated rescue of murine laminin alpha2 chain deficiency.

BACKGROUND: Laminin alpha2 chain mutations cause congenital muscular dystrophy with dysmyelination neuropathy (MDC1A). Previously, we demonstrated that laminin alpha1 chain ameliorates the disease in mice. Dystroglycan and integrins are major laminin receptors. Unlike laminin alpha2 chain, alpha1 chain binds the receptors by separate domains; laminin globular (LG) domains 4 and LG1-3, respectively

En princip om internationell öppenhet – 1 kap. 10 § regeringsformen och socialförsäkringsrätten

Artikeln undersöker vad bestämmelsen om Sveriges EU-medlemskap och om internationellt samarbete i 1 kap. 10 § regeringsformen betyder rättsligt för den offentliga förvaltningen, särskilt avseende socialförsäkringsrätten och Försäkringskassan. En bakgrund till bestämmelsen är internationaliseringen av den offentliga rätten. Utvecklingen har inneburit att en stor del av de normer som svenska myndigh

’Treating Threats - the Ethical Dilemmas of Treating Threatening Patients

This paper considers the impact of threats on professional service workers, especially as these emerge in healthcare services. Based on interviews with healthcare professionals and prison guards, this paper discusses the ethical dilemmas inherent in viewing the doctor-patient relationship from a solely rule-based ethical approach when threatening behaviour is involved. It is argued that under thre
