Large deviations for random evolutions with independent increments in a scheme of Levy approximation
Asymptotic analysis of the problem of large deviations for random evolutions with independent increments in the circuit of the L´evy approximation is carried out. Large deviations for random evolutions in the circuit of the L´evy approximation are determined by the exponential generator for a jump process with independent increments

The article deals with the experience of organizing
theoretical and practical training for intern-doctors,
which were studied in the therapeutic dentistry department.
Effectiveness of the intern-doctors training is
determined by a quality of education at the university,
innovative technologies usage and working on the
therapeutic basis. Acquisition of skills should be
achieved through the independent work with literature
sources, self- education, diagnostic and therapeutic
tasks solution, participation in educational games, and
presentation of reports at the clinical conferences.
Such activities provide a high level of professional
training for the intern-doctors and determine their
readiness to independent professional activity
On random flights with non-uniformly distributed directions
This paper deals with a new class of random flights defined in the real space characterized
by non-uniform probability distributions on the multidimensional sphere. These
random motions differ from similar models appeared in literature which take
directions according to the uniform law. The family of angular probability
distributions introduced in this paper depends on a parameter which
gives the level of drift of the motion. Furthermore, we assume that the number
of changes of direction performed by the random flight is fixed. The time
lengths between two consecutive changes of orientation have joint probability
distribution given by a Dirichlet density function.
The analysis of is not an easy task, because it
involves the calculation of integrals which are not always solvable. Therefore,
we analyze the random flight obtained as
projection onto the lower spaces of the original random
motion in . Then we get the probability distribution of
Although, in its general framework, the analysis of is very complicated, for some values of , we can provide
some results on the process. Indeed, for , we obtain the characteristic
function of the random flight moving in . Furthermore, by
inverting the characteristic function, we are able to give the analytic form
(up to some constants) of the probability distribution of Comment: 28 pages, 3 figure
Integral Representation of Hyperparabolic Equation
In this work, for functions that satisfy a Cauchy problem for hyperparabolic equations, we write
integral equations and solve them using the method of successive approximations
THE DIAGNOSTIC MARKERS’ APPLICATION OF THE ORAL LIQUID IN THE EARLY DIAGNOSTICS OF THE DENTAL MOBIDITY IN THE STAFF OF THE STEEL-MANUFACTURING ENTERPRISES’ EMPLOYEES
The dental health of the industrial enterprises’ workers has specific differences from the average indicators of the epidemiological examinations, which is associated with a negative effect on the tissue and oral cavity of the working zone’s atmosphere. Under prolonged exposure of the low concentrations of harmful substances, i.e, due to the chronic intoxication in the oral cavity can occur as a disease of the mucous membrane, as well as the disease of hard tissues of the teeth. Despite the presence of measures on the occupational safety and accident prevention protection, the industrial environment of the enterprises is an extreme condition for workers, which requires the further development of effective comprehensive methods of the prevention and the treatment of the major dental diseases.
The aim of the work is to carry out the analysis of the specialized scientific literature for the data generalization about modern looks to the use of biological markers for early diagnostics of dental diseases in workers with harmful working conditions.
Materials and methods. We have analyzed and studied the available scientific literature in the last years, which is devoted to the peculiarities of the dental diseases’ spread among the workers of the enterprises with harmful working conditions and the biological markers’ use for their early diagnostics.
Up until recently the use of mouthwash in diagnostic aims was complicated, that is explained by the following: a barrier of hematosalivation, low level of determination, complication of exposure, it is studied not enough, the indexes got not always correlate with such in plasma of blood, and also absence of attention to methodology of collection and storage of tests of this material to realization of analysis. These problems were largely removed as a result of careful study of physiology of salivary glands, development of sensible methods of amplification, methodology of separation and treatment of standards. The last achievements in diagnostics were conditioned by new molecular approaches.
The development of new therapeutic methods is impossible without the establishment of the diagnostic monitoring system to determine the predictors of the disease, its biological markers, criteria for assessing its course, prediction of the possible outcomes and the effectiveness of the therapeutic measures.
Researches are actively conducted the last decades in relation to character of content of markers of bone fabric, oxidative and nitrosative stresses, proteins of endogenous cytoprotection cytoprotection (HSP -, HIF, squirrel Klotho), markers of inflammation in a mouthwash at various stomatological diseases. It is known that 99% of organic molecules, that circulate in plasma, identified in saliva and represent the "regional orientation" of pathobiochemical processes.
Conclusions. Thus, the analysis of literary data showed possibility of biological markers, using in Dentistry as minimum aggressive, informing diagnostic method and screening of dental efficiency of treatment.
Improving the list of saliva biomarkers depends on their stability and accuracy of detection, including the sensitivity and reproducibility of the analyzes, their simplicity of the execution, high sensitivity and specificity
Cytokine levels in the vaginal secretions of healthy and herpes simplex virus-infected women in different phases of menstrual cycle
The role of estrogens in regulating the T-cell immune response and in changing the cytokine profile in biological fluids is well known. The authors monitored the activity of cytokines and interferons in the vaginal swabs of clinically healthy and herpes simplex virus (HSV)-infected women in different phases of the menstrual cycle. Differences were found in cytokine concentrations in the ovulatory and progesterone phases of the cycle. Thus, the HSV-infected women had impaired cytokine balance towards the enhanced activity of proinflammatory interleukins in the ovulatory phase of the cycle and that of anti-inflammatory interleukins in its progesterone phase. This tends to reduce a protective T-cell immune response in the virus-infected women and to maintain chronic virus infection. © 2012
