DIAGNOSTICS ALGORITHM OF DIABETIC POLYNEUROPATHY IN PREDICTION OF CLINICAL COURSE.

AIM: To estimate the importance of new algorithm introducing of PDP diagnostics in practice of NEFU medical institute Clinic in detection of severity level and predicting of clinical course. MATERIALS AND METHODS: 50 people with sensory-motor PDP form among patients with 2 type diabetes were examined on the basis of Clinic of NEFU medical institute. Patients have been divided into 2 groups by disease duration: the first groups were patients with duration of disease till 10 years, the second group--more than 10 years. Diagnostics methods: clinical neurologic, neurophysiological. RESULTS: Patients underwent polymodal sensitivity analysis, computer pallesteziometry, stabilometry, electroneuromyography. The dependence of clinical neurophysiological PDP parametres from severity of the duration of type 2 diabetes has been revealed. CONCLUSION: Thus, dependence of clinical-neurophysiological parametres of PDP severity from the duration of 2 type diabetes has been revealed. The new algorithm raised efficacy of clinical-neurophysiological PDP diagnostics and helped the predicting of the clinical course.

[Sociological analysis of healthcare delivery in Russia regions with inclement natural conditions (in case of the Republic of Altai)].

The paper describes the results of a sociological study of delivery of healthcare in the Republic of Altai to search for ways to improve its quality and to provide access to the local population. Analysis was made with regard to an interdisciplinary, comprehensive approach to considering the range of problems associated with not only the health of local residents and identifying risk factors leading to diseases, but also by determining the possibilities that could promote the minimization of causes that have a considerable impact on the occurrence of diseases and also hamper healthcare delivery in the human settlements of Gornyi Altai, which are difficult of access. The investigation has used sociological and statistical methods. It has been ascertained that the available healthcare forces and means should be today employed at the regional level, by applying the principles of necessary sufficiency in conjunction with the local population's social motivation to be involved in the activity associated with the rendering of medical services. In addition, it is necessary to systemically use mobile medical units as a significant factor for the optimization of medical care to the population living in Russia's regions which are difficult of access.

Phase sensitive shot noise in an Andreev interferometer.

We investigate nonequilibrium noise in a diffusive Andreev interferometer, in which currents emerging from two normal metal/superconductor (N-S) interfaces can interfere. We observe a modulation of the shot noise when the phase difference between the two N-S interfaces is varied by a magnetic flux. This is the signature of phase-sensitive fluctuations in the normal metal. The effective charge inferred from the shot noise measurement is close to q(eff) = 2e but shows phase-dependent deviations from 2e at finite energy, which we interpret as being due to pair correlations. Experimental data are in good agreement with predictions based on an extended Keldysh Green's function approach.

Observation of the Cabibbo-Suppressed Decay Ξ_{c}

We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ_{c}^{+}→pK^{-}π^{+}. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600 GeV/c Σ^{-} beam. The branching fractions of the decay relative to the Cabibbo-favored Ξ_{c}^{+}→Σ^{+}K^{-}π^{+} and Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+} are measured to be B(Ξ_{c}^{+}→pK^{-}π^{+})/B(Ξ_{c}^{+}→Σ^{+}K^{-}π^{+})=0.22±0.06±0.03 and B(Ξ_{c}^{+}→pK^{-}π^{+})/B(Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+})=0.20±0.04±0.02, respectively.

[Blood flow in a renal artery with a deformed vessel wall]. / Techenie krovi v pochechnoi arterii s deformirovannoi sosudistoi stenkoi

Blood flow in a vessel of the kidney arterium type with a deformed vascular wall in the form of stenosis or atherosclerotic patches is described. Rate fields and pressure distribution in the vessel are described. Conclusions are made concerning the behaviour of blood forming elements. Tension of the vascular wall depending on its deformation and blood current parameters are evaluated. The calculation results are in a good agreement with the experimental data.
