RESTRICTION of locomotor activity is one of several techniques used to produce ulcers in experimental animals such as the white rat. This method of ulcer production has been particularly useful as a tool for the investigation of the effect of various factors on ulceration severity. For example, certain drugs, genetic factors, and cyclic activity levels have been shown to influence ulceration ra...

BACKGROUND Studies investigating the nutritional status of patients with leprosy and plantar ulcers are sparse. Therefore, the objective of this study was to describe the protein profile of leprosy patients with plantar ulcers from the Eastern Amazon region. METHODS A case record form was created for 75 patients with leprosy (31 with plantar ulcers and 44 without plantar ulcers) with the foll...

Background: Hemiscorpius lepturus is one of the dangerous scorpions in the world and also in Iran. This kind of scorpion in southern provinces, especially in Khoozestan, has been responsible for stinging a lot of people that resulted in long-standing and dangerous side effects and sometimes mortality. As the study of the effects of this scorpion venom on some laboratory animals can determine th...

A quality of care debate centers on whether pressure ulcers result from factors largely dependent on caregivers, or whether pressure ulcers result from factors associated with patient morbidity. A reduction in incidence, defined as the development of a new pressure ulcer, is the focus of prevention strategies. Yet epidemiological data demonstrates a stability in the incidence of pressure ulcers...

Peptic ulcer predicts gastric cancer. It is controversial if peptic ulcers predict other gastrointestinal cancers, potentially related to Helicobacter pylori or shared lifestyle factors. We hypothesized that gastric and duodenal ulcers may have different impact on the risk of gastrointestinal cancers. In a nationwide cohort study using Danish medical databases 1994-2013, we quantified the risk ...
