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).…

Power training in young athletes: Is it all in the genes?
2018
Introduction. The aim of the study was to evaluate the effects of plyometric and isometric training protocol on power in 46 team sports (basketball: n = 23; volleyball: n = 23) players, also in relation to genetic background (i.e., ACE and PPARA genes polymorphisms). Methods. The following tests were administered: squat jump (SJ), countermovement jump (CMJ), drop jump (dJ), sprint, handgrip, and agility test. Genetic analysis was based on saliva samples. Results. The training protocol proved to be effective in improving jump performance in basketball players and volleyball players, respectively: 25-meter sprint test (p = 0.006; p = 0.008); agility test (p = 0.000; p = 0.000); SJ test (p = 0…
Regards croisés sur la méthodologie de l'écrit 1. De l'intérêt du compte-rendu de lecture
2018
Aux concours du CAPEPS et de l'Agrégation d'EPS, la première épreuve écrite d'admissibilité consiste en une dissertation portant sur les fondements sociohistoriques et épistémologiques de l'éducation physique et sportive. Les rapports de jury insistent sur la nécessité d'adopter une démarche critique et engagée. Ils déplorent, en revanche, des difficultés d'ordre méthodologique dans l'usage de la citation mise en exergue des sujets. Ce double constat interroge les pratiques en formation. Entremêlant les points de vue d'un formateur et d'un étudiant admis à la dernière session de l'Agrégation, cet article propose de discuter l'intérêt du compte-rendu de lecture, avec la volonté d'en démêler …
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 …
Activities of some peptidases and proteinases in germinating kidney bean, Phaseolus vulgaris
1986
The activities of aminopeptidase (EC 3.4.11), dipeptidase (EC 3.4.13), carboxypeptidase (EC 3.4.16), naphthylamidase (EC 3.4.11) and proteinases (EC 3.4.21) were assayed in extracts from the cotyledons and the axial tissues of resting and germinating kidney beans (Phaseolus vulgaris L. cv. Processor). The activities of the alkaline peptidases (aminopeptidase hydrolyzing Leu-Tyr at pH 9.2 and dipeptidase acting on Ala-Gly at pH 8.5) and naphthylamidases (hydrolyzing Leu-β-naphthylamide at pH 6.4) were high in the cotyledons of resting seeds, but decreased during germination. This decrease was faster than the loss of the total nitrogen. On the contrary, the activities of carboxypeptidase (hyd…
Characterization of HLA-DR- and TCR-binding residues of an immunodominant and genetically permissive peptide of the 16-kDa protein of Mycobacterium t…
2004
The 16-kDa protein of Mycobacterium tuberculosis represents an important antigenic target during bacillary latency and, consequently, should be considered as candidate subunit vaccine component. In this study, we have used CD4 T cell clones that recognize the peptide p91-110, an immunodominant and genetically permissive epitope, in the context of five different HLA-DR molecules and truncated and substituted variants of this peptide, to identify the minimal binding sequence (HLA-DR-binding core) and the minimal stimulatory sequence (TCR-binding core), as well as the residues that contact HLA-DR molecules and the TCR. We have found a common 9-mer sequence, spanning amino acids 93-101, as the …
Mapping antigenic epitopes of potato virus Y with antibodies affinity-purified by using overlapping synthetic peptides
1994
Synthetic, overlapping peptides representing the entire amino acid sequence of potato virus Y (PVY) coat protein were used to affinity-purify antibodies from polyclonal antisera to PVY. In testing the binding of the purified antibodies to PVY particles, antigenic epitopes were identified. The N-terminal and C-terminal regions of the PVY coat protein were found to contain most of the antigenic epitopes. The results will facilitate the development of detection methods for PVY based on synthetic peptides.
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…

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…
