[Bond strength of metal brackets to enamel with a Russian adhesive complex: an in vitro study].

Background: The era of using adhesives to fix brackets began in the 70s of the last century. There are eight generations of foreign-made adhesive systems for the restoration of teeth. However, until now, in orthodontics, the development of domestic adhesive systems with improved properties of adhesion of brackets to tooth enamel still important, especially in the posterior teeth.

Pain assessment following endodontic treatment using two automated systems compared to manual treatment in primary molars.

Background: Root canal treatment in primary teeth is quite difficult and time-consuming, especially canal preparation. Pain is the most common negative outcome following root canal treatment, occurring hours or days after treatment. It is an unpleasant experience for both the patient and the dentist.

[INFLUENCE OF BEVERAGES ON THE DENTOALVEOLAR SYSTEM (EXPERIMENTAL STUDY)].

The aim of the study was to determine the influence of various drinking liquids on an the dentoalveolar system in rats. The study was carried out on 25 white male rats from the nursery of Krolinfo branch of the Moscow region which were kept in standard vivarium conditions. Age of rats-3-6 months, weight - 150-200 grams.

[Evaluation of the effect of sodium hypochlorite gel on composite bonding strength to enamel of primary teeth after salivary contamination: in vitro study].

Objective: The study investigated the effect of 2%s odium hypochlorite gel application after post-etching salivary contamination on composite bonding strength to primary teeth enamel.

Material And Methods: The sample consisted of 79 primary human teeth that were extracted no more than one month ago. The sample was randomly divided into four groups: (1) the control group (A) comprised 10 primary teeth, and composites were applied in the traditional manner without any salivary contamination; (2) the second group (B) consisted of 23 primary teeth in which salivary contamination was conducted after etching followed by re-etching and follow-up; (3) the third group (C) comprised 23 primary teeth in which saliva contamination was done after etching followed by washing, drying, and follow-up; and (4) the fourth group (D) comprised 23 primary teeth, in which salivary contamination was conducted after etching followed by application of sodium hypochlorite gel and follow-up.

Geolocation data of irrigation network in water user association's operation area under community-based and provider-based network governance.

Massive irrigation development has influenced the way farmers govern water user associations (WUAs) in Klambu Wilalung Irrigation District in Central Java, Indonesia. Recently, farmers adopt community-based () and provider-based () network governance to manage the WUAs. The physical conditions of the irrigation network have become the primary driver of WUA's governance selection.

[Diagnosis and treatment of acute intestinal obstruction due to gall-stone].

Results of treatment of 43 patients with acute intestinal obstruction due to gall-stones are analyzed. Forty patients were operated, 3 patients were not because of extremely severe state. Enterolythotomy was performed in 27 cases, incision of intestinal wall was carried out directly above the stones (14 cases, group 1), above or below it (13 cases, group 2).

[Hormonal disorders in women with prosopalgia in osteochondrosis of the cervical spine and the possible means for their correction].

Radioimmunoassay was employed to determine basal levels of LH, FSH, prolactin, total testosterone and 17 beta-estradiol in plasma from 52 pre- or postmenopausal women with prosopalgia consequent to cervical osteochondrosis. The measurements were made before and after laser treatment. Different from the control, basal levels of the hormones and the trends in their changes due to laser therapy depended on the patients' age and the disease stage.

[Interstitial hyperthermia method in spontaneous tumors].

To induce hyperthermia of spontaneous tumors in dogs an interstitial method of heating was used: electrodes in the form of injection needles were implanted around tumors. Necessary temperature levels could not be attained in a dog with circumanal angiosarcoma because the tumor was well vascularized and had a considerable volume. No thermal damage of the animals' skin was observed during all sessions of hyperthermia.

[Model study of the structure of heat release when using interstitial hyperthermia on tumors].

Heat distribution structures are given with application of the interstitial method of heating with the 1.7 MHz frequency, 8 implanted needles arranged in 2 rows were used as electrodes. Heat distribution structures are obtained on the basis of the mathematical model which was constructed in the electrostatic approximation and with the investigation of the spatial distribution of temperatures in the tissue-equivalent phantom.

[Contibution of the X chromosme to the increased resistance of inbred Drosophila melanogaster hybrids to physical effects].

Effects of high sub-lethal temperature and UV-irradiation on surviving of inbred lines of Drosophila melanogaster and its F1 hybrids derived from reciprocal crosses between these lines are investigated. High resistance of F1 hybrids to these factors was observed as compared with that of parental inbred lines. D.
