Humic-Based Polyelectrolyte Complexes for Dust Suppression.

The present study proposes a novel application of humic substance-aminosilsesquioxane polyelectrolyte complexes (HS-ASQ) as dust suppressants. These complexes are synthesized through the reaction between humic substances (HS) and 3-aminopropyltriethoxysilane (APTES) in aqueous solution, resulting in the formation of active silanol groups that can bind to mineral surfaces and condense, forming gels. The HS-ASQ compositions were found to have a high sorption capacity for dust particles and could form coatings on their surface without cementing the dust, making them potentially useful for environmental applications.

[Predictors for development of major cardiovascular events in elderly patients with severe and extremely severe chronic obstructive pulmonary disease in combination with early stages of chronic kidney disease].

Unlabelled: The aim of the study was to evaluate efficacy, safety and treatment compliance for different ASA forms (Aspirin Cardio, Cardiomagnyl and Trombo Ass) in a 6-month study.

Materials And Methods: A prospective 6-month open, comparative study originally included 600 patients with IHD and stable angina who received chronic therapy with different forms of aspirin. In the prospective part of the study, these patients were subdivided into four groups: group 1 consisted of 200 patients switched to Aspirin Cardio; group 2 - 200 pa - tients receiving chronic therapy with this drug; group 3 - 100 patients continuing on the Trombo Ass treatment; and group 4 - 100 pa - tients who had been treated with Cardiomagnyl for a long time.

[Safety and efficacy of long-term treatment with different ASA forms in patients with stable IHD and a high risk for development of gastropathy by data from a cross-sectionals study].

Aim: To study indexes of efficacy, safety and compliance for different ASA forms (Aspirin-Cardio, Cardiomagnyl, Thrombo ASS) used in stable IHD.

Materials And Methods: An open, cross-sectional study compared three groups of patients consisting of 200 patients each who had stable IHD and a high risk of gastrointestinal disorders and who received a long-term antiaggregant monotherapy with one of ASA drugs (group 1, Aspirin Cardio; group 2, Thrombo ASS; group 3, Cardiomagnyl). Efficacy, safety and compliance with the treatment were evaluated using standard tests and analogue scales; dyspepsia symptoms were evaluated using a special, additionally developed questionnaire.

[Heart failure with preserved and slightly impaired ejection fraction and cardiovascular events: Pathogenetic interrelations as a part of the cardiovascular continuum].

Aim: To evaluate the effect of decompensated HF with preserved or slightly impaired EF on the risk of cardiovascular complications during a 5‑year follow-up.

Materials And Methods: 33 patients with arterial hypertension and HF with preserved or slightly impaired EF (NT-proBNP ≥125 pg/ml, mean, 500.1±590.

[Secondary flowering: the induction and development abnormalities].

Time of flowering substantially determines a level of reproductive success of populations. As a rule, plants of a seasonal climate blossom once a year, during period which is optimal for successful pollination and the subsequent maturing of fruits (seeds). However, secondary flowering is registered for many species.
