Enantioselective Catalytic Aldol Reactions in the Presence of Knoevenagel Nucleophiles: A Chemoselective Switch Optimized in Deep Eutectic Solvents Using Mechanochemistry.

In the presence of different nucleophilic Knoevenagel competitors, cyclic and acyclic ketones have been shown to undergo highly chemoselective aldol reactions with aldehydes. In doing so, the substrate breadth for this emerging methodology has been significantly broadened. The method is also no longer beholden to proline-based catalyst templates, , commercially available O--Bu-L-threonine is advantageous for acyclic ketones.

[Effect of complex generalized treatment using zinc electrophoresis and electromagnetic field of millimeter range waves on clinical, physiological and bacteriological indices in patients with chronic generalized periodontitis].

Total of 73 patients with chronic generalized periodontitis have been studied. Among them in 38 patients a light form of this pathology was observed, while in 35 - mean form. It has been established that a complex treatment with the usage of zinc electrophoresis and electromagnetic field of millimeter range waves evokes an improvement of the indices of stomatological status right up to normalization; increases partial pressure of oxygen tension in gums and has a bactericidal action on the microflora of parodontal pockets.

[The state of immune status in patients with chronic periodontitis before and after combined treatment with physical methods].

Total of 73 patients with chronic generalized periodontitis at the age from 20 to 62 years have been studied. In 38 patients severe form of pathology was observed, while in 35--an average form. At admission to hospital both general and local immunity disorders were observed in patients; changes in immunological indices progressed with the deterioration of pathology.

[Roentgenomorphological correlations in the diagnosis of pneumonias in patients with combined, craniocerebral, thermal injury and exogenous poisonings].

The clinical roentgenological and postmortem morphological data were analyzed and correlated in 219 patients with combined (60), craniocerebral (38), thermal (46) injury and exogenous poisonings (75), who developed pneumonias in the course of the treatment. All the patients underwent chest roentgenography in the anteroposterior projection and in the supine position. The rate of intravital identification of pneumonias accounted for 73.

[The x-ray picture of pulmonary circulation in the course of acute myocardial infarct].

A study was made of the time course of lesser circulation (LC) in 80 patients with acute transmural myocardial infarction and in 20 patients with chronic coronary heart disease with the help of chest x-ray. A possibility of preclinical detection of left ventricular insufficiency was confirmed. The capacity of roentgenography to reflect objectively the time course of LC disorder and its correlation with primary determination of a degree of changes, age, cardiac sizes, the expression of aortic atherosclerosis, pleurocardiac reactions and site of myocardial infarction were defined.
