Abstract
In the course of the study it was formed a scientifically based concept of an objective assessment of human spatial orientation during performing of complex locomotion. This approach is to perform remote monitoring of cyclic locomotion of step motion «walking on the spot» in terms of the surrounding space. During the test is carried out the spectral evaluation of the acceleration values of the lower extremities in the band from 1 to 10 Hz. It was found that the frequency spectrum reflects the processes of qualitative implementation of spatial orientation. This indicator can be used to objectively assess bio-kinematic stabilize the body in space. The developed technology is innovative and can be used as a rapid method for diagnostic motor and coordinative disorders of various origins.

Abstract
The trace element composition of the hair using X-ray fluorescence analysis in individuals of different sexes over 18 years, suffering from diffuse alopecia (ALD) is studied. It was found that women with ALD had a deficit of trace elements such as sulfur ( p = 0.0001), iron ( p = 0.0052), potassium ( P = 0.0012), chromium ( p = 0.0016), selenium ( p = 0.0192) and manganese ( p = 0.0342). men with ALD had calcium deficiency ( p = 0.0000), sulfur ( p = 0.0014) and zinc ( p = 0.0003).

Abstract
The experimental determination and justification of optimal exposure parameters for the high-intensity pulsed magnetic field (HIPMF) has been made. The technique for the high-intensity magnetotherapy was developed. Preclinical and clinical trials were made. The study allowed authors to give proof of the HIPMF effectiveness in the medical treatment and rehabilitation of the sportsmen with the locomotor apparatus traumas. The technique demonstrated evident miostimulating, anti-inflammatory and anti-edematous actions to promote rehabilitation potential and somatic mobilization of sportsmen.

Abstract
The possibility of using biosensors (live bacteria) for revealing and visualization of molecular clusters which form in fluid water was shown by the example of the effect of laser irradiation on the water structure. The transverse dimensions of these clusters were also defined.

Abstract
A mathematical model of brain water metabolism is presented. The model takes into account the latest clinical and experimental data on cerebral fluid exchange. The model makes it possible to assess, on quantitative bases, the cerebral water metabolism and its conclusions might have clinical implications.

Abstract
There were analyzed 745 cards outpatient dental health of children from 3 to 14 years. Subjected to expert analysis of 270 cases of surgical treatment of periodontitis temporary molars. Analysis of the data showed that 62.2 % of the removal of first and second molars temporary exacerbation occurred as a result of chronic inflammation. The greatest number of deletions from the ages of 6 to 8 years is 38.4 %. During the period of physiological change of teeth in 56.6 % removal cases of temporary molars diagnosis followed by the chronic apical periodontitis and periapical abscess.

Abstract
It was aimed to evaluate safety and adverse effects of rhythmic transcranial magnetic stimulation (rTMS) in patients with muscular dystonia (MD). There were treated 163 patients. It was proved that the use of low-frequency rTMS is well tolerated. The obtained results allows to recommend rTMS in the complex system of treatment and rehabilitation of patients with MD.

Abstract
A method of treating fully edentulous mandible with removable designs of dentures relying on dental implants is described. Data from the literature over the past 10 years is studied. After learning deficiencies a new method for fixing the total denture mandible implant is proposed. This method will increase the effectiveness of treatment fully edentulous mandible.

Abstract
The objective of the research was to develop a method for the assessment of balance impairment in Parkinson's disease, based on videomotion analysis. The developed method for the assessment of balance function in the patients with Parkinson's disease does not require expensive equipment, and may be utilized while pre- and postoperative examination of patients with Parkinson's disease.

Abstract
Today, using of nanostructured materials in microelectromechanical systems (MEMS) is very perspective. One of such materials is anodic aluminum oxide that has electrical and mechanical properties not worse than other materials that are currently used in manufacturing of MEMS devices. This article presents the results of research in methodology and measurement of Young's modulus of free aluminum oxide films.

Abstract
Comparative analysis of the X-ray examination methods revealed the higher informational content of the cone-beam computed tomography up to 5,51±0,61% than the orthopantomography in the diagnosis of endoperiodontitis in patients aged 35-44 years with periodontal diseases. It has been proved that the cone-beam computed tomography gave the possibility to visualize the main pathways interconnecting the endodontium and periodontium, which has been an important step in the endoperiodontitis diagnosis.
