Transfistulous endoscopic sequestrectomy in the treatment of infected pancreatic necrosis.

Objective: To develop an effective minimally invasive method for the treatment of infected pancreatic necrosis.

Material And Methods: There were 168 patients with infected pancreatic necrosis who were treated at the Regional Clinical Hospital No. 2 between 2011 and 2018.

Superconducting Long-Range Proximity Effect through the Atomically Flat Interface of a BiTe Topological Insulator.

We report on structural and electronic properties of superconducting nanohybrids made of Pb grown in the ultrahigh vacuum on the atomically clean surface of single crystals of topological BiTe. In situ scanning tunneling microscopy and spectroscopy demonstrated that the resulting network is composed of Pb-nanoislands dispersed on the surface and linked together by an amorphous atomic layer of Pb, which wets BiTe. As a result, the superconducting state of the system is characterized by a thickness-dependent superconducting gap of Pb-islands and by a very unusual position-independent proximity gap between them.

Photon Transport in a Bose-Hubbard Chain of Superconducting Artificial Atoms.

We demonstrate nonequilibrium steady-state photon transport through a chain of five coupled artificial atoms simulating the driven-dissipative Bose-Hubbard model. Using transmission spectroscopy, we show that the system retains many-particle coherence despite being coupled strongly to two open spaces. We find that cross-Kerr interaction between system states allows high-contrast spectroscopic visualization of the emergent energy bands.

[Minimally invasive surgical interventions in the treatment of severe acute pancreatitis].

Objective: To improve the outcomes in patients with severe destructive pancreatitis undergoing minimally invasive surgery.

Material And Methods: There were 482 patients with acute destructive pancreatitis for the period from 2007 to 2016. Non-infected acute destructive pancreatitis was diagnosed in 58% (=280) of patients, infected pancreatic necrosis - in 42% (=202) of patients.

[CONTROL OF APPLICATION EFFICACY OF THE ASCENDING GAS--FLUID STREAM METHOD IN TREATMENT OF DIFFUSE PERITONITIS].

The ascending gas and fluid stream method was applied in 12 patients with repeated purulent diffuse peritonitis. The number of leukocytes was determined in lavage fluid in order to estimate the efficacy of the method. Dynamics of general laboratory and clinical indices was compared with dynamics of leukocytes quan- tity.

[Micromechanical characteristics of restoration stomatological materials and human dental enamel and dentin].

Polished sections of human teeth and 11 Russian and foreign restoration materials (silver amalgam, cements, and polymer-based materials) were studied with an MTI-3M microhardness meter. Microhardness immediately under loaded diamond indentor of the device, elastic and plastic deformations were evaluated. Dental enamel is characterized by the greatest microhardness.

Effect of equilibrium fluctuations on superfluid density in layered superconductors.

Using a phenomenological approach based on the fluctuation-dissipation theorem we calculate suppression of superconducting currents due to phase fluctuations and find that, in contrast to a recent prediction, the effect of thermal fluctuations cannot account for linear temperature dependence of the superfluid density in high-T(c) superconductors at low temperatures. Quantum fluctuations are found to dominate over thermal fluctuations at low temperatures. Near T(c) sizable thermal fluctuations are found to suppress the critical current in the stack direction stronger than in the direction along the layers.

[Clinical laboratory research on the properties of Aquafresh toothpaste].

The study of the teeth in 35 patients with chronic catarrhal generalized gingivitis and periodontitis of moderate severity using tooth paste Aquafresh for a months confirmed high cleansing, antiinflammatory and refreshing potential of the paste which, moreover, has a good taste and mint flavor. Laboratory tests showed low abrasibility of the paste, its ability to raise by 12.5% the resistance of the enamel to demineralizing action of the lemon juice.

[The characteristics of the development of caries in human dental fissures based on microhardness data. Its diagnosis, treatment and prevention].

Hygienic status of the teeth was assessed after Fyodorov-Volodkina and Green-Vermillion in 500 patients aged 26 to 68 consulted for caries, chronic and acute periodontitis. A good hygienic status of the teeth was observed in 70 subjects: the Fyodorov-Volodkina hygienic index was 1, the Green-Vermillion index O. The Fyodorov-Volodkina index from 1,7 to 5 in 430 patients, depending on the hygienic habits.

[The bone tissue of the jaws in congenital and acquired deformities].

Biophysical parameters of the jam bones were examined in patients with congenital and acquired deformations. Ash content, density, mineral content, and microhardness were estimated in 58 patients aged 17 to 28. The mean values of these characteristics were found to be unrelated to the individual features and the type of the changes in the bone tissue, associated with deformations of the jaws.

Wear resistance and microhardness of human teeth.

The dependence between the wear resistance and microhardness of the different tissues of human teeth has been studied. During these experiments the proportionality between the wear volume of the tissues under study and their microhardness (by indentation and scratching methods) has been observed.

[A comparative evaluation of the cleaning and anti-inflammatory actions of sample therapeutic-prophylactic toothpastes].

Therapeutic and preventive action of Lugela toothpaste was compared with similar salt-containing toothpastes manufactured in this country and abroad. Its anti-inflammatory and cleansing effects were found superior to those of similar pastes.

[The effect of toothbrushes on human dental enamel and dentin wear].

The authors compare the effects of natural (porcine) and synthetic (Toinex, USA, and Eschalon, France) bristle and rough toothbrushes on the tooth enamel and dentin in the course of toothbrushing. No abrasive effects were detected when brushing normal teeth in clear water. The rate of enamel and dentin abrasion in tooth powder or tooth paste suspension depended on the shape of bristle cut and particularly on the toothbrush roughness.

[Dependence of the dentinal abrasion of human teeth on their microhardness].

The dentin resistance against abrasion was studied as related to its microhardness. Sections of 15 intact teeth were investigated (central upper incisors). Water suspensions (40% weight-to weight) of dicalcium phosphate (DCP, FRG; and DKF-1 and DKF-2, USSR) were used as abrasives.
