AIMS To assess and compare the self perceived work related stress among emergency department (ED) and general ward (GW) nurses, and to investigate its relation with salivary IgA and lysozyme. METHODS One hundred and thirty two of 208 (63.5%) registered female ED and GW nurses participated in the study. A modified mental health professional stress scale (PSS) was used to measure self perceived...

The plasticity region of Helicobacter pylori is a large chromosomal segment including isolate-specific open reading frames with characteristics of pathogenicity islands. It remains unclear whether genes in the plasticity region play a role in the pathogenesis of gastric mucosal inflammation and gastroduodenal disease. Our aim was to assess the role of selected genes in the plasticity region in ...

OBJECTIVE To assess use of stress ulcer prophylaxis in patients admitted to five pediatric intensive care units (PICUs) in Porto Alegre, Brazil. METHODS This was a multicenter, prospective, cross-sectional observational study. PICUs were visited on randomly defined days between April 2006 and February 2007, and the medical records of admitted patients were reviewed. Patients whose records had...

Gastric ulcer is a multifaceted, pluricausal illness. Knowledge of the pathophysiology of gastric ulcer disease remains incomplete. Current pharmacological management of gastric ulceration is directed primarily at the reduction or neutralization of gastric acid secretion despite evidence that patients with this disease often exhibit normal gastric secretory activity. Attempts have been made to ...

involvement in intestinal function is carried through two " Collateral Damage " in the other chapters in disparate areas of interest. One describes the role of cytokines in the IgA response, to Nervous System which much of the mucosal response is dedicated. N. Lycke presents a conceptually pleasing and logically In Defense of the Brain: Current Concepts in the Im-formatted discussion of the for...

Hazardous and unhealthy environmental changes are rising continuously in modern society due to rapid industrialization and urbanization. In addition to environmental contamination, interest on electromagnetic wave(EMF) is also increasing. EMF is reported in a lot of papers to cause DNA damage, infertility, oxidative stress, cell cycle change, apoptosis, gene expression abnormality, tumorigenesi...

Intestinal mucosal barrier, mainly consisting of the mucus layer and epithelium, functions in absorbing nutrition as well as prevention of the invasion of pathogenic microorganisms. Paneth cell, an important component of mucosal barrier, plays a vital role in maintaining the intestinal homeostasis by producing antimicrobial materials and controlling the host-commensal balance. Current evidence ...

Recent studies have suggested that dietary fiber exerts a therapeutic effect on inflammatory bowel disease patients. The aim of this study was to evaluate the effects of a dietary fiber, germinated barley foodstuff (GBF), derived from the aleurone and scutellum fraction of germinated barley against dextran sulfate sodium (DSS)-induced experimental colitis in rats. Sprague-Dawley rats were fed a...

BACKGROUND Critically ill patients in the intensive care unit (ICU) are at risk of clinically important gastrointestinal bleeding, and acid suppressants are frequently used prophylactically. However, stress ulcer prophylaxis may increase the risk of serious adverse events and, additionally, the quantity and quality of evidence supporting the use of stress ulcer prophylaxis is low. The aim of th...

BACKGROUND Dental procedures may cause stress and increase the salivary cortisol levels. It is important to known if apparently simple procedures such as professional dental prophylaxis at low speed (DP) are stressful for children with dental behaviour management problems (DBMP) to help with behaviour guidance strategies. This longitudinal study aimed to evaluate if DP changes a physiological m...
