AIM To observe changes in gastric biomarker levels with age and effects of Helicobacter pylori (H. pylori) infection in a healthy population, and explore factors associated with gastric biomarkers. METHODS Three hundred and ninety-five subjects were selected and underwent physical examinations, biochemical tests, and measurement of serum pepsinogen (PG) I and II, gastrin-17 (G-17) and H. pylo...

The inhibition of prostaglandin (PG) synthesis is at the center of current anti-inflammatory therapies. Because cyclooxygenase-2 (COX-2) inhibitors and nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the formation of multiple PGs, there is currently a strong focus on characterizing the role of the different PGs in the inflammation process and development of arthritis. Evidence to date sug...

PURPOSE/OBJECTIVES To evaluate psychometric properties of an instrument designed to measure individualized health-related quality of life (HRQOL). DESIGN Repeated measures of self-reported quality of life. SETTING An outpatient radiation therapy department in the western part of the United States. SAMPLE 86 adults with cancer receiving their first course of radiation therapy. METHODS Th...

Disruption of microfilaments in human umbilical vein endothelial cells (HUVEC) with cytochalasin D (cytD) or latrunculin A (latA) resulted in a 3.3- to 5.7-fold increase in total synthesis of prostaglandin E(2) (PGE(2)) and a 3.4- to 6.5-fold increase in prostacyclin (PGI(2)) compared with control cells. Disruption of the microtubule network with nocodazole or colchicine increased synthesis of ...

The endothelium comprises a cellular barrier between the circulation and tissues. We have previously shown that activation of protease-activated receptor 1 (PAR-1) and PAR-2 on the surface of human coronary artery endothelial cells by tryptase or thrombin increases group VIA phospholipase A(2) (iPLA(2)β) activity and results in production of multiple phospholipid-derived inflammatory metabolite...

In honeybee flight muscle, there are close matches between physiological flux rates and the maximal activities (Vmax; determined using crude homogenates) of key enzymes catalyzing non-equilibrium reactions in carbohydrate oxidation. In contrast, phosphoglucose isomerase (PGI), which catalyzes a reaction believed to be close to equilibrium, occurs at Vmax values greatly in excess of glycolytic f...

BACKGROUND Helicobacter pylori infection and subsequent gastric inflammation have been proposed as risk factors for the development of insulin resistance and cardiovascular disease. In this study we assessed the possible association of H. pylori bacterial load, and serum biomarker of gastric inflammation with cardiometabolic risk factors in diabetic patients. METHODS In this cross-sectional s...

INTRODUCTION: Costa Rica has among the highest mortality rates from gastric cancer in world, largely due to late detection. It is therefore important that economically and logistically sustainable screening implemented order detect risk of developing cancer. We have previously shown low pepsinogen (PG) values infection with Helicobacter pylori-CagA+ are associated atrophy Rican populations. OBJ...

Abstract Introduction Mazindol is the first partial orexin 2 receptor agonist and triple monoamine reuptake inhibitor in development for treatment of narcolepsy. Clinician Patient Global Impression (CGI PGI, respectively) cataplexy excessive daytime sleepiness were assessed as secondary endpoints phase (POLARIS, NLS-1021) multicenter study mazindol ER adult participants with narcolepsy type 1 (...

BACKGROUND Currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. The purpose of this study was to evaluate the value of serological parameters including serum pepsinogen I (PGI), pepsinogen II (PGII) and pepsinogen I: II ratio for the screening atrophic gastritis and gastric cancer. METHODS The study population consisted of 132 dyspeptic patients who...
