Milk as an Essential Source of Iodine in Latvian Population
2017
Abstract Milk and dairy products are studied as alternative iodine sources, because salt iodisation is controversial due to high salt consumption leading to cardiovascular diseases. However, the iodine concentration in milk markedly varies. This study evaluated the iodine concentration in cow’s milk available in the Latvian market. Iodine and fat concentration was analysed with a spectrophotometer “Varian Cary 50” based ISO 2446:2008 in 20 milk samples. Data from the Central Statistical Bureau and survey among pregnant women were used to analyse milk product consumption and its impact on iodine status. Average iodine concentration in milk samples was 457.6 (179.6) μg/L, winter samples had a…
MEASURING REGIONAL CONVERGENCE - AN APPLICATION TO THE EUROPEAN UNION AND ROMANIA
2012
Attention of regional economic convergence has a great place in economics literature. The application of spatially explicit methods of data analysis to the convergence question has yielded important insights on regional economic growth. The literature on regional income inequality, although somewhat older than the convergence literature, has been slower to adopt new spatially explicit methods of data analysis. Application of recently developed methods of spatial econometrics to the question of regional convergence has yielded a more comprehensive and multidimensional view of regional economic growth. This article aims to identify the techniques and methods use for regional convergence and i…
Joda deficīts grūtniecēm teritoriālā griezumā un tā ietekme uz intelektuālo attīstību bērniem Latvijā
2015
Latvijā ilgstoši pastāv joda deficīts, kas ir bīstams sabiedrības veselībai un intelektuālajai attīstībai. Pat neliels joda deficīts grūtniecības periodā izraisa bērna IQ pazemināšanos, līdz ar to vēlāk arī iespējamu valsts IKP per capita samazināšanos. Uzdevumi: izvērtēt joda pietiekamību Latvijas grūtniecēm reģionālā griezumā, sakarības ar saistītiem faktoriem, kā arī censties identificēt sakarību starp joda koncentrāciju urīnā (JU) skolēniem un atzīmēm valsts eksāmenos. Visos Latvijas reģionos grūtniecēm konstatēts joda deficīts (mediānā JU 64.5-89.9 µg/g Cr). Starp grūtnieču JU un jodu saturošu vitamīnu lietošanu statistiski ticama sakarība atrasta tikai Zemgalē, bet ar jodsāls lietošan…
EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE
2009
The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…
An Approach to Delineate Groundwater Bodies at Risk: Seawater Intrusion in Liepāja (Latvia)
2018
Groundwater quality in coastal areas is frequently affected by seawater intrusion as a consequence of intensive water consumption. To achieve “good chemical status” of a groundwater body according to Water Framework Directive the effects of saline or other intrusions should not be observed. Groundwater pumping in former decades has caused a significant seawater intrusion into confined aquifer in Liepāja and has led to deterioration of relatively wide coastal area of the third largest city in Latvia. However, the area affected by seawater intrusion is a small part of groundwater body F1 which overall chemical status is good. Thus, no specific management measures have been applied to explore …

Una poética de las ruinas. Testimonio y alegoría de Aníbal Quijada
2009
El texto de Aníbal Quijada Cerco de púas ejemplifica la doble vinculación de los testimonios del exilio chileno. Por una parte, éstos debieron inscribirse en las estrategias internacionales de denuncia contra la dictadura militar y, por otra, la comunidad cultural latinoamericana hizo de los testimonios un elemento esencial para la redefinición del concepto mismo de lo literario. El testimonio de Quijada desarrolla, en ese contexto, unas estrategias narrativas y de representación que alejan su textura de la mayoría de los testimonios de la época.The text of Aníbal Quijada Cerco de púas, is a good example of the double filiation of the testimonies of Chilean exile. In one hand these testimon…
Ruta chalepensis L. (Rutaceae) leaf extract: chemical composition, antioxidant and hypoglicaemic activities.
2017
Ruta chalepensis L. (Rutaceae) leaf extract was investigated for its chemical profile and antioxidant and hypoglycaemic properties. The antioxidant effects were investigated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), Chi-carotene bleaching, and metal chelating activity assays. The carbohydrate-hydrolysing enzymes inhibition assay was used to test the hypoglycaemic potential. R. chalepensis showed a high content of hesperidin and rutin with values of 591.9 and 266.7 mg/g dry extract, respectively. The extract exhibited a promising protection of lipid peroxidation (IC50 value of 16.9 mu g/mL) and inhibited both alpha-amylase and alpha-glucosidase enzymes in a concentration-dependent manner. The…
Jurisdiction in cases of divorce, legal separation or marriage annulment
2021
The subject of coordination is fundamental for the functioning of jurisdictional rules of the Regulation n.2016/1103 on matrimonial property regimes and Regulation n.2016/1104 on the property consequences of registered partnerships. Both Property Regimes Regulations have the purpose of gathering litigation before the courts of one Member State and have the related procedures managed by the courts of the same Member State. Recital 34 of Regulation No. 2016/1103 specifies that matters of matrimonial property regime related to proceedings pending before the court of a member state hearing an application for divorce, legal separation or marriage annulment should be dealt with by the courts of t…
A minireview on NHE1 inhibitors. A rediscovered hope in oncohematology.
2015
Background: Na+/H+ exchanger-1 (NHE-1) is involved in pH regulation and is up-regulated in different malignancies. Activation of NHE-1 is one way for allowing cells to avoid intracellular acidification and protect them against apoptosis. Inhibitors of NHE-1 are able to decrease intracellular pH and induce apoptosis. Some statins can also act by partial inhibition of NHE-1. This review presents progress in understanding the mechanisms of action of these inhibitors, connections with certain genetic mutations and acquired treatment resistance, as well as new patents on them. Methods: A MEDLINE search for original and review articles using key terms, Na+/H+ exchanger, leukemia, cariporide, and …
