background: helicobacter pylori (hp) is a gram negative, spiral shaped bacterium which colonizes the gastric mucosa and induces gastroduodenal complications varying from mild gastritis with no clinical complications to peptic ulcer diseases and even gastric malignancies. the rate of hp infection is 30-50% in developed countries whereas it has been rated up to 80% of the adult population in deve...

BACKGROUND Disadvantaged groups are often not reached by mainstream health promotion interventions. Implementing health promotion (HP) interventions in social economy companies, can be an opportunity to reach those people. The implementation of these interventions in social economy companies was studied. Factors that could be related to the implementation of HP and being supportive towards impl...

54 patients (22 females, 32 males, age 21-79, mean 45 years) referred for upper gastrointestinal endoscopy were investigated. Helicobacter pylori (HP) infection was determined using histology (H&E and Giemsa stain), rapid urease test (CLO) and serology (Cobas Core Anti-H. pylori EIA). Density of HP colonization was determined in gastric antral (3 biopsy specimens) and body mucosa (2 biopsy spec...

AIM To determine gastric tissue lactoferrin (Lf) levels of Helicobacter pylori- (Hp-) positive and -negative patients and its effect on anemia. METHODS Cases in which initial presentation was of abdominal pain and that were Hp-positive at endoscopy were included. Hp-positive cases and -negative controls were divided into two groups. RESULTS The study included 64 cases (average: 10.2 ± 0.4 y...

Haptoglobin is a plasma hemoglobin-binding protein that limits iron loss during normal erythrocyte turnover and hemolysis, thereby preventing oxidative damage mediated by iron excess in the circulation. Haptoglobin polymorphism in humans, characterized by the Hp(*1) and Hp (*2) alleles, results in distinct phenotypes known as Hp1-1, Hp2-1 and Hp2-2, whose frequencies vary according to the ethni...

Hippocampal injury in the Alzheimer's disease (AD) pathological process is region-specific and magnetic resonance imaging (MRI)-based measures of localized hippocampus (HP) atrophy are known to detect region-specific changes associated with clinical AD, but it is unclear whether these measures provide information that is independent of that already provided by measures of total HP volume. There...

Heparin (HP) inhibits the proliferation of bovine pulmonary artery smooth muscle cells (BPASMC's), among other cell types in vitro. In order to develop a potential therapeutic agent to reverse vascular remodeling, we are involved in deciphering the relationship between the native HP structure and its antiproliferative potency. We have previously reported the influence of the molecular size and ...

Hypoxic preconditioning (HP) is a rapid and reversible proadaptive response to mild hypoxic exposure with such a response protecting cells from subsequent hypoxic or ischemic insult. HP mechanisms are of great interest because of their therapeutic potential and insight into metabolic adaptation and cell death. HP has been widely demonstrated in the vertebrate subphylum but not in invertebrates....

Sciatic nerve injury (SNI) results in neuropathic pain, which is characterized by the excessive Ca2+ entry, reactive oxygen species (ROS) and apoptosis processes although involvement of antioxidant Hypericum perforatum (HP) through TRPM2 and TRPV1 activation has not been clarified on the processes in SNI-induced rat, yet. We investigated the protective property of HP on the processes in the sci...
