[Development and evaluation of simulation methods for manual skills training in 'Removable dentures' module].

Unlabelled: To determine the effectiveness of a simulation method of teaching manual skills modulo 'removable dentures' in a clinical setting.

Material And Methods: The material 1 phase of the study were 82 people, students of 3 courses, divided into a control group where the training was conducted with the use of standard phantoms and group study which used a dental simulator CDS 100 of V generation. Material 2 stages presented 48 people who participated in phase 1 and divided into groups similar to the 1 stage, young professionals in 2016.

Preparation and synthetic applications of aryl tetraflates (ArOSO2CF2CF2H).

We have recently developed an improved synthetic route to 1,1,2,2-tetrafluoroethanesulfonic acid (HCF2CF2SO3H, TFESA) and explored the applications of this newly available superacid in catalysis. Low volatility, ease of handling, and a convenient 1H NMR handle make this acid an attractive alternative to triflic acid. TFESA can also be converted to several of its derivatives: anhydride, sulfonyl chloride, and sulfonyl fluoride, which provide a good entry point for the synthesis of aryl sulfonates.

Photoinduced charge transfer mediated by DNA-wrapped carbon nanotubes.

We report our observation of solution photochemical reactions catalyzed by carbon nanotubes. Addition of sub-millimolar Ag+ ions into a solution of DNA-wrapped carbon nanotubes (DNA-CNT) leads to a strong charge-transfer band in the UV region of the optical absorption spectrum. Light irradiation of the Ag+/DNA-CNT mixture results in reduction of Ag+ to Ag nanoparticles and concomitant oxidation of water.

Copper(I)-catalyzed synthesis of azoles. DFT study predicts unprecedented reactivity and intermediates.

Huisgen's 1,3-dipolar cycloadditions become nonconcerted when copper(I) acetylides react with azides and nitrile oxides, providing ready access to 1,4-disubstituted 1,2,3-triazoles and 3,4-disubstituted isoxazoles, respectively. The process is highly reliable and exhibits an unusually wide scope with respect to both components. Computational studies revealed a stepwise mechanism involving unprecedented metallacycle intermediates, which appear to be common for a variety of dipoles.

Structural and mechanistic investigations of the oxidation of dimethylplatinum(II) complexes by dioxygen.

The oxidation of (tmeda)Pt(II)(CH(3))(2) (1, tmeda = N,N,N',N'-tetramethylethylenediamine) to (tmeda)Pt(IV)(OH)(OCH(3))(CH(3))(2) (3) by dioxygen in methanol proceeds via a two-step mechanism. The initial reaction between (tmeda)Pt(CH(3))(2) and dioxygen yields a hydroperoxoplatinum(IV) intermediate, (tmeda)Pt(OOH)(OCH(3))(CH(3))(2) (2), which reacts with a second equivalent of (tmeda)Pt(CH(3))(2) to afford the final product 3. Both 2 and 3 have been fully characterized, including X-ray crystallographic structure determinations.

[Indirect electric stimulation of the auditory neural structures in the complex treatment of sensorineural hearing loss and subjective noise in the ears].

Indirect or transdermal electrostimulation (ES) was used in 62 patients suffering from neurosensory hypoacusis stage II-III. The procedure was conducted with the help of an +electric stimulator made on the country and a device providing an automatic change of the polarity. Disappearance of noise in the ears, better hearing, 10-15 dB shifts in auditory thresholds were achieved in 20 patients (32.

[The role of genetic factors in determining the ECG indicators].

ECG parameters were examined in 62 families with a history of arterial hypertension. A genetical-and-dispersion analysis of ECG parameters were made. There was a high genetic determination with X-chromosomal effect, R-R interval duration, and Makruse index values.

[New principles and technology in the management of medical research].

New principles of management, planning, and finance of medical science with the aim to increase its efficacy are discussed. The transfer from financing the scientific administration to financing research is taken into account. The technology of expert examination is analysed as this is a basis for adopting decisions in the management of medical science.

[Analysis of the indicators of central and peripheral hemodynamics in families with arterial hypertension].

Arterial pressure was studied by ++tacho-oscillography, and the central and peripheral hemodynamics were examined by tetrapolar rheography in members of 62 families with essential arterial hypertension. A geneticodispersion analysis was made of phenotypic dispersion of the parameters under study. The genetic determinant with an X-chromosome effect was established for minimal and lateral systolic pressure; that with a maternal effect for mean pressure.

[Semantics of genetic correlation analysis].

A theory of genetic-correlation analysis has been put forward on the basis of notions concerning general and special codispersions . The complete set of genetic-correlation indexes is received and their genetic-statistical meaning revealed. The models for genetical component analysis of general and special codispersions of correlative connections are constructed.
