Stipa ×fallax nothosp. nov. (Poaceae), from western Pamir Alai Mts (Tajikistan), is described and illustrated. Field observation, numerical analyses of morphology, and pollen grain viability data show that it originated from hybridization between S. drobovii and S. macroglossa subsp. macroglossa, species representing sections Smirnovia and Stipa, respectively. Stipa ×fallax is morphologically close to S. ×alaica and S. ×hissarica, but is distinguished by its shortly pilose lower part of the awn and densely pubescent leaves. Characters distinguishing S. ×fallax from its parental species as well as similar hybrid taxa in section Smirnovia that also grow in Central Asia are presented. The micromorphology of lemmas and leaves of S. ×fallax and its parental species was examined by scanning electron microscopy. We also propose the new combination Stipa drobovii var. iskanderkulica (Tzvelev) M.Nobis & A.Nowak.

We describe and illustrate a new nothospecies in the genus Laelia: L. × meavei Cetzal & E.A. Pérez-García. This new taxon is most likely the result of the introgression between Laelia rubescens fo. peduncularis and L. dawsonii fo. dawsonii. The description of L. × meavei is based on cultivated plants coming from a single locality: Sola de Vega, Oaxaca, on Mexico’s Sierra Madre del Sur. One of the putative parents, L. dawsonii fo. dawsonii, is widely cultivated in the region and known in the wild, but current wild populations are small and scattered. In turn, L. rubescens is typically a lowland species, but in this region it is known to grow at higher elevations and these populations are referable to L. rubescens fo. peduncularis. Flowers of Laelia × meavei are similar to those of L. rubescens, but they are larger and longer lasting, whereas the plants look more like a small L. dawsonii fo. dawsonii. Furthermore, to be consistent with the broad circumscription of Laelia followed here, we provide a new combination for the recently described Encarbacenia perezgarciae Archila & Szlachetko. Finally, the following new combination is proposed, L. dawsonii fo. chilapensis (Soto-Arenas) E.A. Pérez-García & Cetzal.

The size, shape and surface morphology of human erythrocytes (RBC) were examined by scanning electron microscopy (SEM), of the fixed material directly and by transmission electron microscopy (TEM) of surface replicas to compare the relative merits of these two observational procedures for this type specimen.A sample of human blood was fixed in glutaraldehyde and washed in distilled water by centrifugation. The washed RBC's were spread on freshly cleaved mica and on aluminum coated microscope slides and then air dried at room temperature. The SEM specimens were rotary coated with 150Å of 60:40- gold:palladium alloy in a vacuum evaporator using a new combination spinning and tilting device. The TEM specimens were preshadowed with platinum and then rotary coated with carbon in the same device. After stripping the RBC-Pt-C composite film, the RBC's were dissolved in 2.5N HNO3 followed by 0.2N NaOH leaving the preshadowed surface replicas showing positive topography.

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

Relevance. Empirical treatment of vaginitis is indicated due to its polymicrobial etiology and limited microbiological analysis. The aim of the study was to study the combination of ornidazoleneomycinprednisoloneeconazole (ONPE, Elzhina) as a first-line drug for local treatment of patients with various forms of non-specific vaginitis. Materials and methods. The study included 55 non-pregnant women aged 18 to 50 years (381.5 years) who had clinical and laboratory signs of acute vaginitis. Results. All patients at the initial treatment complained of pathological discharge, 47 (85.5%) noted itching, burning, pain in the genital area of various degrees of severity, 17 (30.9%) discomfort when urinating, 9 (16.4%) unpleasant smell, 8 (14.5%) dyspareunia, 4 (2.2%) complained of sensations of a foreign body in the vagina. The clinical and laboratory effectiveness of treatment was 89.1% (49). In 6 (10.9%) patients, clinical improvement was noted, with the remaining laboratory signs of aerobic vaginitis. Conclusion. The new combination of ornidazoleneomycinprednisoloneeconazole (ONPE, Elzhina ) has a good efficacy and safety profile and can be used to initiate empirical treatment of non-specific inflammatory diseases of the lower genital tract.
