Synthesis and enhanced room-temperature thermoelectric properties of CuO-MWCNT hybrid nanostructured composites.

This work presents the synthesis of novel copper oxide-multiwalled carbon nanotube (CuO-MWCNT) hybrid nanostructured composites and a systematic study of their thermoelectric performance at near-room temperatures as a function of MWCNT wt% in the composite. The CuO-MWCNT hybrid nanostructured composites were synthesized by thermal oxidation of a thin metallic Cu layer pre-deposited on the MWCNT network. This resulted in the complete incorporation of MWCNTs in the nanostructured CuO matrix.

Association of elevated vitamin B with oncohematological diseases in a cohort of 79,524 patients from Latvia.

Aim: Currently there are some large-scale studies of elevated total vitamin B in relation to diseases and their prognosis. Aim of this retrospective study was to determine association of increased B as an additional diagnostic marker of oncohematological diseases by a statistical analysis of clinical data of 79,524 patients.

Materials And Methods: Overall Latvian population representative data on B  testing in 79,524 patients were obtained from laboratory database.

Iodine deficiency during pregnancy: a national cross-sectional survey in Latvia.

Objective: Low iodine intake during pregnancy may cause thyroid dysfunction, which results in inadequate fetal brain development. In the absence of a universal salt iodization programme, we conducted a nationwide survey of iodine deficiency in pregnant women in Latvia.

Design: A countrywide twenty-cluster survey, with at least twenty women per cluster.

Changing patterns of serological testing for celiac disease in Latvia.

Background And Aims: A number of recent guidelines have discouraged the use of the old anti-gliadin tests for the detection of celiac disease; tissue transglutaminase IgA (tTGA) and anti-endomysial (EMA) tests are recommended instead. Our aim was to evaluate how the current recommendations have been applied in real practice. The secondary aim was to evaluate the positivity rates provided by different test types.
