In vitro susceptibility of 120 strains of Neisseria gonorrhoeae isolated in Kyrghyzstan.
BACKGROUND: The World Health Organization has established a worldwide program for gonococcal antimicrobial surveillance, but so far no data on gonococcal susceptibility in Central Asia are available. GOAL: The need for biological data on the susceptibility of Neisseria gonorrhoeae in Kyrghyzstan, to enable adaptation of the national treatment protocol for gonococcal infections, led Médecins Sans Frontières and Epicentre to conduct a survey in collaboration with the Alfred Fournier Institute in Paris and the health authorities in Bishkek. STUDY DESIGN: In vitro susceptibility of N gonorrhoeae strains was determined with use of the reference agar-plate dilution technique. RESULTS: Results for 11 antibiotics tested on 120 strains of gonococci showed a low proportion (11.7%) of penicillinase-producing N gonorrhoeae and high proportions of intermediate or resistant strains to the majority of the antibiotics tested, including fluoroquinolones (>or=25% of strains resistant). All the strains were susceptible to spectinomycin, and only two strains had decreased susceptibility to cefixime. CONCLUSION: The therapeutic choices available in Kyrghyzstan appear to be limited to cephalosporins and spectinomycin
Metabolic cardioprotection: new concepts in implementation of cardioprotective effects of meldonium
Recent studies confirm the need to find means to correct ischemic / reperfusion injury due to the hemodynamic medicine, which are already known do not have the proper cardioprotective effects. Key issue is the possibility of drug effects on the mitochondria of cardiomyocytes that controls the aerobic metabolism and maintenance of ATP admission into cardiomyocyte
Social and psychological features of inter-cultural adaptation of Russian students in different universities
Modern globalisation processes, the rapid entry of Russia into the world community, have given more opportunities to interact with various ethnic groups ranging from short-term tourist and business contacts to complex processes of migration and emigration. Migrants and visitors have different goals for staying in a new country, meanwhile the researchers note a lot in common within the adaptation processes of both groups. In particular, tension, stresses and experience of cultural shock during adaptation are observed. Therefore, it is necessary to conduct psychological studies not only of migrants who come for a long time to a new country, but also of visitors, i.e., interns, students who come to study in foreign universitie
Spectral multiplicity for powers of weakly mixing automorphisms
We study the behavior of maximal multiplicities for the powers of
a weakly mixing automorphism . For some special infinite set we show the
existence of a weakly mixing rank-one automorphism such that
and for all . Moreover, the cardinality
of the set of spectral multiplicities for is not bounded. We have
and , , . We
also construct another weakly mixing automorphism with the following
properties: for but ,
all powers have homogeneous spectrum, and the set of limit points of
the sequence is infinite

Physical properties of thermoelectric zinc antimonide using first-principles calculations
We report first principles calculations of the structural, electronic,
elastic and vibrational properties of the semiconducting orthorhombic ZnSb
compound. We study also the intrinsic point defects in order to eventually
improve the thermoelectric properties of this already very promising
thermoelectric material. Concerning the electronic properties, in addition to
the band structure, we show that the Zn (Sb) crystallographically equivalent
atoms are not exactly equivalent from the electronic point of view. Lattice
dynamics, elastic and thermodynamic properties are found to be in good
agreement with experiments and they confirm the non equivalency of the zinc and
antimony atoms from the vibrational point of view. The calculated elastic
properties show a relatively weak anisotropy and the hardest direction is the y
direction. We observe the presence of low energy modes involving both Zn and Sb
atoms at about 5-6 meV, similarly to what has been found in Zn4Sb3 and we
suggest that the interactions of these modes with acoustic phonons could
explain the relatively low thermal conductivity of ZnSb. Zinc vacancies are the
most stable defects and this explains the intrinsic p-type conductivity of
ZnSb.Comment: 33 pages, 8 figure
