Bioaccessibility of inorganic arsenic species in raw and cookedHizikia fusiformeseaweed
2004
Samples of Hizikia fusiforme edible seaweed, a commercially available dried food with high concentrations of total arsenic (t-As) and inorganic arsenic (i-As), both raw and cooked (boiling at 100 °C, 20 min), were selected for the bioaccessibility study. Cooking caused a significant reduction in the concentrations of t-As (30–43%) and i-As (46–50%), despite which the i-As contents in the cooked product were high (42.7–44.6 µg g−1 seaweed). An in vitro gastrointestinal digestion (pepsin, pH 2, and pancreatin–bile extract, pH 7) was applied to the seaweed to estimate arsenic bioaccessibility (maximum soluble concentration in gastrointestinal medium) of t-As, i-As, arsenic(III) and arsenic(V).…

Helicobacter pylori infekcijas un atrofiskā gastrīta izplatības analīze Kazahstānas populācijā
2019
Ievads. Neskatoties uz to, ka Kazahstānā ir augsta kuņģa vēža incidence, ir ierobežojami dati, kas informētu par H. pylori un kuņģa atrofiskā gastrīta izplatību šajā valstī. Darba mērķis. Noteikt un izanalizēt H. pylori infekcijas un atrofiskā gastrīta izplatību asimptomātiskiem 40 – 64 gadus jauniem Kazahstānas iedzīvotājiem. Materiāli un metodes. Dalībniekiem noteica anti-H. pylori IgG ≥10 U/mL un PGI, PGII ar lateksa-aglutinācijas metodi. Tika analizētas divas PG robežvērtības: PGI ≤ 70 ng/mL un PGI/II ≤ 3 un PGI ≤ 30 ng/mL un PGI/II ≤ 2. Darbā tika pielietota aprakstošā statistikas metode, secinošas statistikas metodes (T-tests, Hī kvadrāta tests). Par svarīgu statistisko nozīmību tika …
Biomarķieru metode kuņģa gļotādas atrofijas noteikšanai
2014
Promocijas darba „Biomarķieru metode kuņģa gļotādas atrofijas noteikšanai” anotācija latviešu valodā Pētījumā tika veikta kuņģa biomarķieru metodes validācija, salīdzinot metodes rezultātus ar standartizēti veiktiem morfoloģijas izmeklējumu rezultātiem. Iegūtie dati parāda labu korelāciju starp PGI/II attiecību un kuņģa korpusa daļas atrofiju (p<0.0001) ar jutību (83.3%), kopējo precizitāti (86.7%). Biomarķieru samazinājums PGI un PGI/II tika noteikts atbilstoši paaugstinoties OLGA gastrīta stadijām. Mazāk pieņemama bija samazinātās sG-17 vērtības uzrādīja labu korelāciju ar kuņģa vārtnieka daļas atrofiju (p=0.007), neskatoties uz jutību, kas bija ievērojami zema (36.8%). Samazinātām G-17 u…
Trial profile: pilot study of the multicentre randomised trial of H. pylori eradication and pepsinogen testing for prevention of gastric cancer morta…
2019
Purpose: The GISTAR Pilot study is part of a large multi-centre randomised trial conducted in Latvia with the main aim to evaluate preventive strategies to decrease mortality from gastric cancer in high-risk areas, especially in the Baltic States and Eastern Europe. Participants: A total of 3,447 apparently healthy, asymptomatic participants (40-64 y/o) were recruited between 2013 and 2015 for the GISTAR pilot study. Participants were interviewed for socio-economic status, lifestyle, environmental and occupational exposures, medical history, family history of diseases, and dietary habits. Participants were randomly assigned to either Intervention (n=1,724) or Control (n=1,723) group. The in…
Zinc acexamate inhibits gastric acid and pepsinogen secretion in the rat.
1990
Abstract Pretreatment with zinc acexamate (25–100 mg kg−1 i.p.) inhibited acid and pepsinogen secretion in the pylorus-ligated rat. Zinc acexamate (5–50 mg kg−1 p.o.) also inhibited the increases in acid secretion induced by carbachol (10 μg kg−1) and 2-deoxy-D-glucose (200 mg kg−1) in the perfused stomach of the anaesthetized rat. A delayed antisecretory effect was observed with this drug on histamine induced responses. High concentrations of zinc acexamate (10−5-10−2 M) did not modify the in-vitro activity of pepsin. Administration of zinc acexamate resulted in an increase in the presence of pepsinogen at the mucosal level. A morphological examination of the gastric mucosa confirmed an ac…
Helicobacter pyloriand Non-malignant Diseases
2008
In 2007 Helicobacter pylori research continued to deal with some controversies raised in the last decade. The main problems remain unsolved: peptic ulcer disease negative for H. pylori, synergism of H. pylori infection and aspirin and other nonsteroidal anti-inflammatory drugs or cyclooxygenase 2 specific inhibitors, the role of H. pylori eradication in uninvestigated and nonulcer dyspepsia, and the possible protective effect of H. pylori infection against gastroesophageal reflux disease and its complications such as Barrett's esophagus and adenocarcinoma. The incidence and prevalence of peptic ulcer disease as well as ulcer-related mortality are continuing to decline all over the world. Th…
Non-Invasive Diagnosis of Gastroesophageal Reflux Disease Using Gastrin- and Pepsinogen-Based Tests
2018
Abstract Gastrin-17 (G-17), pepsinogen-1 (Pg1) and pepsinogen-2 (Pg2) reflect the functional state of gastric mucosa and are used for non-invasive diagnosis and screening of atrophic gastritis. The aim of the study was to clarify if erosive reflux disease (ERD) or non-ERD (NERD) can be distinguished from other dyspeptic conditions in patients, in a non-invasive manner using specific biomarkers. Levels of G-17, Pg1, and Pg2 were measured in 141 ERD patients (median age 48 years, males — 68), 122 NERD patients (median age 45 years, males — 32) and 410 control patients (median age 50 years, males — 97). Levels of biomarkers in ERD and NERD groups were compared to controls. Median levels of G-1…
T1078 The Validity of a Biomarker Method for Indirect Detection of Gastric Mucosal Atrophy Versus Standard Histopathology
2008
Background Atrophy of the stomach mucosa is considered to be premalignant lesion for gastric cancer development; easy identification of this condition from a blood-sample would allow identifying the group of individuals at increased risk for cancer development.
Markers for gastric cancer premalignant lesions: where do we go?
2012
Only a small proportion of patients infected with <i>Helicobacter pylori</i> develop gastric cancer during their lifetime. At the same time, this type of cancer remains an important cause of mortality globally. The current interventional strategies have not been successful in decreasing the global burden of the disease; therefore, biomarkers for the identification of the individuals at high risk as well as those in the early stage of the disease is of high importance. In addition, predicting the point of no return for the development of the malignancy is of particular interest; whether atrophy, intestinal or spasmolytic polypeptide-expressing metaplasia, or some of their subtype…
