Somatostatin receptor subtypes were labeled with the somatostatin analogs [125I]CGP 23996 and [125I]MK 678 and the distribution of these receptors in rat brain was investigated using quantitative autoradiographic techniques. [125I]CGP 23996 and [125I]MK 678 specifically label different populations of somatostatin receptors in rat brain. In a number of brain(More)
BACKGROUND A variety of definitions of evidence-based practice (EBP) exist. However, definitions are in themselves insufficient to explain the underlying processes of EBP and to differentiate between an evidence-based process and evidence-based outcome. There is a need for a clear statement of what Evidence-Based Practice (EBP) means, a description of the(More)
BACKGROUND The magnitude of risk of death related to surgery and anaesthesia is not well understood. We aimed to assess whether the risk of perioperative and anaesthetic-related mortality has decreased over the past five decades and whether rates of decline have been comparable in developed and developing countries. METHODS We did a systematic review to(More)
BACKGROUND There is growing evidence that better outcomes are achieved when anticoagulation is managed by anticoagulation clinics rather than by family physicians. We carried out a randomized controlled trial to evaluate these 2 models of anticoagulant care. METHODS We randomly allocated patients who were expected to require warfarin sodium for 3 months(More)
Jasmonic acid (JA) signalling can influence plant defense and the production of plant volatiles that mediate interactions with insects. Here, we tested whether a JA seed treatment could alter direct and indirect defenses. First, oviposition levels of herbivorous mites, Tetranychus urticae, on JA seed-treated and control tomato plants were compared. They(More)
Insect pheromones offer potential for managing pests of crop plants. Volatility and instability are problems for deployment in agriculture but could be solved by expressing genes for the biosynthesis of pheromones in the crop plants. This has now been achieved by genetically engineering a hexaploid variety of wheat to release (E)-β-farnesene (Eβf), the(More)
Insulin-like growth factor binding protein-3 (IGFBP-3) is a key regulatory molecule of the IGF axis and can function in a tissue-specific way as both a tumor suppressor and promoter. Triple-negative breast cancer (TNBC) has high tumor expression of IGFBP-3 associated with markers of poor prognosis and, although accounting for 15-20% of all breast cancers,(More)
The complex mechanisms that cells have evolved to meet the challenge of constant exposure to DNA-damaging stimuli, also serve to protect cancer cells from the cytotoxic effects of chemo- and radiotherapy. IGFBPs appear to be involved, directly or indirectly, in some of these protective mechanisms. Activation of p53 is an early response to genotoxic stress,(More)
We have examined the regulation of an insulin-like growth factor-binding protein-3 (IGFBP-3) protease secreted by MCF-7 human breast cancer cells using a ligand-binding assay that relies on the decrease in affinity for des(1-3)IGF-I that occurs when IGFBP-3 becomes proteolyzed. IGFBP-3 protease activity was not altered by treatment of MCF-7 cells with(More)
OBJECTIVES The clinical impact of preoperative physiotherapy on recovery after joint replacement remains controversial. This systematic review aimed to assess the clinical impact of prehabilitation before joint replacement. DESIGN We searched PubMed, Embase and Cochrane CENTRAL up to November 2015 for randomised controlled trials comparing prehabilitation(More)
