Abstract Objective. To assess the impact of increased use of low-dose aspirin, other non-steroidal anti-inflammatory drugs (NSAIDs), warfarin, corticosteroids and selective serotonin re-uptake inhibitors (SSRIs) on the site and outcome of non-variceal gastrointestinal (GI) bleeds. Methods. Retrospective review of 731 patients with peptic ulcer bleeds (PUBs), non-ulcer, non-variceal upper (NUUPGIBs

The article investigates the potential existence of an order founded by Hedvig Nordenflycht.

Projektet har haft som mål att i samarbete med människor med funktionsnedsättning utvärdera en navigationstjänst baserad på vänskap, personkännedom, mobiltelefoni, GPS och digitala kartor. Med navigation menas att transportera sig till ett avsett mål. I

Mobile telephone calls in public places often entail the revelation of intimate details about the caller's life to strangers. This article reports some results of the authors eavesdropping on mobile phone calls in public places and also takes the first step into analysis of the fascinating mix of visibility and inaccessibility, intimacy and alienation that is the mobile telephone call in a public

This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. The details of the duct geometry were as follows: the cros

The reasons for loss of credibility are first scientism and evasion, which feed oversimplification and confusion as the primary reasons. A case study from central Sudan is used to illustrate of these issues. Credibility has drained away with the deflection of focus from matters that are patently “ desertification” ; and with the deployment of confusing science. The choice to emphasize land degrada

Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be

Background and Objective: Laser-induced fluorescence was studied in normal and tumour tissue of rat after intravenous injection of delta-amino levulinic acid (ALA). The aim of the study was to investigate the protoporphyrin IX accumulation in different tissue types in rat after systemically administered ALA. Study Design/Material and Methods: A malignant rat tumour and normal tissue from 13 differ

The pathophysiology of myocardial infarction (MI) may differ depending on whether it occurs early or late in life. We tested the hypothesis that risk factor pattern differs according to the age at MI.
