Himalayan Species

In 2014 Sukhorukov & Kushunina taxonomically restored the forgotten name Chenopodium pallidum applicable to a Himalayan taxon and designated its lectotype (a specimen in P) and also an epitype (in MW). However, in 2015 they published a correction to their article and demonstrated that the lectotype of C. pallidum in fact belongs to Atriplex and is most probably conspecific with A. schugnanica. The new combination Atriplex pallida was proposed, with A. schugnanica cited in its synonymy. The species of Chenopodium accepted by Sukhorukov & Kushunina in 2014 as C. pallidum was described in 2015 as C. harae Sukhor. (as “harai”), with its holotype in MW being the same specimen as the epitype of C. pallidum. However, when introducing these nomenclatural novelties, the authors did not apply properly the provisions of the ICN, according to which the rejection of an epitype (as long as its supported type retains its status) is extremely complicated, or almost impossible without conservation. Moreover, the application of a name is ultimately established by its epitype, not by the type the epitype supports (in this case, the lectotype). Following the relevant articles of the ICN, it is concluded that (1) Chenopodium pallidum, by its epitypification (but not lectotypification), is the correct name for a Himalayan species of Chenopodium (despite the fact that its lectotype in P belongs to Atriplex), (2) C. harae and Atriplex pallida are homotypic synonyms of C. pallidum; and (3) Atriplex schugnanica (if taxonomically accepted) is the correct name for a species of Atriplex from the Pamir, Karakoram, and Himalayas. It is concluded that plant taxonomists, in order to avoid nomenclatural confusion, should be extremely careful with epitypifications and should not propose epitypes without the utmost necessity. A proposal to amend the Code aimed at better regulation of the existing procedure of epitypification is desirable.

Himalayan Species

Senecio pentanthus (Asteraceae, Senecioneae) has been previously placed in synonymy with Synotis triligulata. Our critical examination of herbarium specimens (including type material) and living plants of S. pentanthus demonstrates that it can be easily distinguished from Syn. triligulata by the leaf serration and the number of phyllaries and florets. We therefore reinstate the independent specific status of S. pentanthus and propose a new combination, i.e. Syn. pentantha. Lectotypification is made for Syn. pentantha herein. A key to all the known species in Syn. ser. Microglossae and Syn. vagans, a species placed in Syn. ser. Erectae but actually more closely similar to those in the former series, is provided.

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.

Main Factors

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.
