Methyl and Ethyl Ethers of Glycerol as Potential Green Low-Melting Technical Fluids.

The study is dedicated to the consideration of lower alkyl ethers of glycerol as potential components of low-melting technical fluids (e.g., heat transfer fluids, hydraulic fluids, aircraft de-icing fluids, etc.

In Situ-Generated, Dispersed Cu Catalysts for the Catalytic Hydrogenolysis of Glycerol.

The present study is dedicated to the experimental verification of a concept for the hydrogenolysis of glycerol over in situ-generated Cu dispersed particles (Cu-DP). The Cu-DP were generated by in situ reduction of a precursor salt (Cu(OAc), CuSO, CuCl) in the presence of KOH and were active in glycerol conversion under hydrogen (T = 200-220 °C, p(H) = 1-4 MPa), where 1,2-propylene glycol (PG) and lactic acid (LA) were detected to be the main products. The influence of the reaction conditions (temperature, hydrogen pressure, reaction time, catalyst-to-feed ratio and the KOH/Cu ratio) on the yields of the products is described.

[Lung Hyperinflation in Chronic Obstructive Pulmonary Disease and Long-Term Outcomes of Percutaneous Coronary Intervention].

Objective: to assess the effect of lung hyperinflation (LHI) in patients with chronic obstructive pulmonary disease (COPD) on longterm outcomes of percutaneous coronary intervention (PCI).

Materials And Methods: Patients with COPD who suffered stable ischemic heart disease and underwent PCI (n=135) were included in a prospective cohort study. LHI was found in 60 patients, while 75 patients had no LHI.

[Ability to Overcome the Thrombocyte Resistance to Acetylsalicylic Acid in Patients With Coronary Artery Disease After Myocardial Revascularization With Coronary Stenting].

Resistance to acetylsalicylic acid (ASA) in patients with coronary artery disease is a poor predictor for the development of atherothrombotic complications. In 277 patients with coronary artery disease suffered uncomplicated coronary angioplasty with stent implantation, we was estimated arachidon-induced platelet aggregation during treatment with acetylsalicylic acid by bedside VerifyNow Assay test at 28-90 days after the intervention. It was found that 18.

[Comparative evaluation of efficacy of histological and cytological methods of H. pylori primary diagnosis in pyloroduodenal ulcer complicated by hemorrhage].

In 48 patients, suffering gastroduodenal ulcer disease, complicated by hemorrhage, cytological and histological investigations were conducted to reveal helicobacter infection. There was established, that sensitivity, specificity and accuracy of smears--the gastric mucosa imprints--cytological investigation exceeds such of histological investigation of biopsies. In more than 80% patients, in whom pyloroduodenal ulcer, complicated by hemorrhage, was diagnosed, Helicobacter pylori (H.
