First Measurement of Transverse-Spin-Dependent Azimuthal Asymmetries in the Drell-Yan Process.

The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190  GeV/c π^{-} beam and a transversely polarized ammonia target. Three azimuthal asymmetries giving access to different transverse-momentum-dependent (TMD) parton distribution functions (PDFs) are extracted using dimuon events with invariant mass between 4.

Electromechanical analysis of a symmetric piezoelectric/elastic laminate structure: theory and experiment.

The dynamic characteristics of a piezoelectric laminate cantilever structure treated as an actuator are analyzed by electroelasticity. General formulation of calculations for displacement sensitivity, electric current, electromechanical coupling coefficients, and results from parametric analyses are presented for axial expansion/contraction, transverse bending, and expansion/contraction-bending coupled motion. The frequency response of displacement and electrical current and the displacement sensitivity were experimentally measured.

Coronary endarterectomy during off-pump coronary artery bypass surgery.

Coronary endarterectomy (CEA) is often combined with coronary artery bypass grafting (CABG), which is performed on cardiopulmonary bypass (CPB). Recent advances in off-pump surgical technique and cardioanesthesiology, along with the increasing number of patients with high risk of CPB complications made it possible and desirable to execute CEA on a beating heart. Russian scientific literature lacks reports on these interventions.

Species, population and age diversity in cell resistance to adhesion of Neisseria meningitidis serogroups A, B and C.

The variation of cell adherence of meningococci serogroups A, B and C and influenza viruses was investigated in 11 animal species and in humans of different age groups (1st, 2nd, 3rd and 4th weeks; 2nd-3rd months; 4th-12th months, 2nd-3rd years; and 18th-60th years of life) as well as in women during pregnancy (17th-36th weeks) and childbirth. Red blood cells of all animals tested as well as of human newborns were absolutely resistant to attachment of meningococci. In neonatal and the later periods the human cells become far differently sensitive individually to meningococcal adhesion.

Comparative analysis of the molecular heterogeneity of ceruloplasmin from human blood and breast milk.

The content of ceruloplasmin (Cp) was determined in 96 samples of human breast milk using rocket immunoelectrophoresis and measurement of Cp oxidase activity. The concentration of immunoreactive Cp in milk decreased about 9 times during the first 20 days of lactation while the specific oxidase activity decreased only 4 times. Two-dimensional electrophoresis of purified milk Cp before and after its treatment with chelating agents showed that copper atoms in milk Cp are more sensitive to EDTA treatment that those in blood Cp.

[The ontogeny of the cell receptors of the adhesion of meningococci and influenza viruses].

Specific age and individual features of the adhesion of Neisseria meningitidis, groups A, B and C, and influenza viruses, types A and B, to red blood cells of humans aged 0-60 years were studied. The study revealed that the red blood cells of newborns, in contrast to those of persons of older age groups, are highly resistant to N. meningitidis adhesion, but highly sensitive to the adhesion of influenza viruses, though to a varying degree.

[The range of individual sensitivity to adhesion by Neisseria meningitidis serogroup B in young men].

5,340 young adult males, including 5,149 healthy persons, 141 N. meningitidis carriers, 25 patients with generalized meningococcal infection and 6 patients with nasopharyngitis of meningococcal etiology, were examined. The study revealed that red blood cells of 17.

[The adhesive properties of meningococci from serogroups A, B and C].

The adhesive properties of 261 meningococcal strains have been studied by the methods of the hemagglutination test, the test of adhesion on buccal epithelial cells and electron microscopy. The study has revealed that adhesive properties can be observed in the strains of all groups under study (A, B and C) isolated from patients and carriers, including those isolated from the nasopharynx, blood and liquor, adhesive properties occurring in newly isolated strains with greater frequency than in museum ones. The simultaneous use of all three above-mentioned methods increases the possibility of the detection of meningococcal strains with adhesive activity.

[The potentials of a unified polyclinic-hospital system in raising the quality of the diagnosis and the efficacy of the differentiated therapy of bronchial asthma patients].

The authors review potential approaches to the upgrading of the diagnosis at the out- and inpatient stages of the rendering medical assistance to patients suffering from bronchial asthma (BA). Show the necessity of the counselling specialized aid, additional studies of the signs of atopy, wise combination of non- and medicamentous treatment methods to enhance the efficacy of the treatment of BA patients. Provide evidence for the advisability of solving the organizational problems concerned with a closer interaction of the polyclinic and hospital with the leading medical institutions on the problem "Pathology of the Respiratory Organs".
