A scalable data transmission scheme for implantable optogenetic visual prostheses.

Objective: This work described a video information processing scheme for optogenetic forms of visual cortical prosthetics.

Approach: The architecture is designed to perform a processing sequence: Initially simplifying the scene, followed by a pragmatic visual encoding scheme which assumes that initially optical stimulation will be stimulating bulk neural tissue rather than driving individual phosphenes. We demonstrate an optical encoder, combined with what we called a zero-run length encoding (zRLE) video compression and decompression scheme-to wirelessly transfer information to an implantable unit in an efficient manner.

[Modern strategies for cardiac rehabilitation after myocardial infarction and percutaneous coronary intervention].

Modern cardiac rehabilitation represents a structured, multicomponent program, which includes physical activity, education of the patient, modification of the health behavior, and psychological and social support. In EU countries, only 44.8% of patients with ischemic heart disease receive a recommendation to participate in any form of rehabilitation, and only 36.

Observational study of nasopharyngeal carriage of Neisseria meningitidis in applicants to a military academy in the Russian Federation.

Objective: To determine the carriage and the serogroup distribution of Neisseria meningitidis in military academy applicants in the Russian Federation.

Design: This was a prospective, observational study of adults aged >18years from a military academy; applicants who had samples taken on arrival (Day 1), and applicants who had samples taken after passing exams (Day 30) and 60days after arrival. N.

[Harmonic imaging analysis for assessment of morphological changes in mini-pig alveolar bone by normal and increased functional load].

The aim of the study was to reveal the mastication forces effect on the microstructure of mandible bone tissue of mini-pigs by Fouirier harmonic imaging analysis of bone sections images of back scattered electrons and assessment of calcium and phosphorous distribution maps obtained by roentgenofluorescence technique. The results showed that by higher functional loads not only the total content of mineral elements in the bone matrix increased but also the of the low-frequency harmonics in the image spectrum indicating structural heterogeneity decrease in bone mineralization.

[Use of Fourier analysis in hystomorphometry].

The mandible alveolar bone tissue of mini-pig was evaluated by means of radiospectral analysis. Fourier analysis of mineral content distribution in bone slices showed that loss of masticatory load leads to focal demineralization. With time the demineralization foci increased in amount, not in size.

CK2 phosphorylation of an acidic Ser/Thr di-isoleucine motif in the Na+/H+ exchanger NHE5 isoform promotes association with beta-arrestin2 and endocytosis.

Internalization of the Na(+)/H(+) exchanger NHE5 into recycling endosomes is enhanced by the endocytic adaptor proteins β-arrestin1 and -2, best known for their preferential recognition of ligand-activated G protein-coupled receptors (GPCRs). However, the mechanism underlying their atypical association with non-GPCRs, such as NHE5, is unknown. In this study, we identified a highly acidic, serine/threonine-rich, di-isoleucine motif (amino acids 697-723) in the cytoplasmic C terminus of NHE5 that is recognized by β-arrestin2.

[Experimental substantiation of parameters and strength characteristics of new endodontic-endoosseous implant construction].

Postoperative tooth stump is not able to endure usual functional loads adequately that leads to enhanced resorption of bone tissues surrounding root and loss of the tooth. Based on math computer simulation of mode of deformation of biomechanical model "metal-ceramic construction--endodontic-endoosseous implant (EEI)--stump of operated tooth--bone tissue of the jaw" new domestic EEI parameters were elaborated which improved greatly biomechanical properties of tooth with operated roots. Strength characteristics of new EEI were studied.

[Evaluation of the effectiveness of anecaine in central segmental blockades in orthopedic-traumatologic interventions].

Efficacy of anecaine (A) (bupivacaine, Pliva) and marcaine (M) (bupivacaine, Astra) in central neuroaxial block combined with sedation is compared. In the group with epidural block (n = 167, ASA I-III), 102 patients were given anecaine and 65 marcaine in equivalent doses. In the group with spinal block (n = 82, ASA I-III), anecaine was administered to 52 and marcaine to 30 patients.

Temperature dependence of laser-induced fluorescence of nitric oxide in laminar premixed atmospheric-pressure flames.

The temperature dependence of laser-induced NO A (2)?(+)-X (2)? fluorescence in the hot gases of natural gas-air flames, seeded with known quantities of NO, has been determined experimentally by means of a difference method. The flame temperature at three fixed equivalence ratios was changed when the mixture velocity was varied through a water-cooled, flat-flame burner and was measured by coherent anti-Stokes Raman spectroscopy. When the possible reburning of part of the seeded NO is allowed for, the results in the range 1700-2150 K are best described by the temperature dependence obtained from a model in which quenching corrections are neglected, as in the case of a saturated two-level system, when millijoule pulse energies are used.

Analysis of laser-induced-fluorescence carbon monoxide measurements in turbulent nonpremixed flames.

The influence of fluctuating concentrations and temperature on the laser-induced-fluorescence (LIF) measurement of CO in turbulent flames is described, under conditions in which the fluorescence and the temperature are measured independently. The analysis shows that correlations between CO concentration and temperature can bias the averaged mole fraction extracted from LIF measurements. The magnitude of the bias can exceed the order of the average CO mole fraction.
