Management of commercial activities of a freight forwarding company in market conditions

At the beginning of 2020, problems arose that will affect the further development of the economy and transport, firstly, the withdrawal of Saudi Arabia and the United Arab Emirates from the OPEC deal, secondly, the fall in the price of Brent oil by more than 30%, thirdly, the outbreak of the coronavirus infection COVID-19, which has largely affected enterprises in all industries. The development of the country’s economy in the global world economy is characterized by volatility and the presence of risks associated with the presence in it of countries with different levels of economic development, economic structure, orientation of the economy, the social structure of society, and the quality of the labor force. The market of road transport services is characterized by a high level of competition in the market. This is due to the following factors: market saturation, the optimal level of tariffs, the volatility of the country’s market economy and the dependence of the transport services market on industrial production, namely on shippers and consignees. Commercial activity can be interpreted as part of entrepreneurial activity related to the sale of goods and services for profit. As the main directions for improving commercial activities, it is planned to integrate marketing and logistics services, which will reduce risks at the stages of movement and storage of products; optimization of business processes of the organization; increasing the company’s rating based on the choice of a reliable carrier; rational selection of a logistics operator

High genetic diversity of measles virus, World Health Organization European region, 2005-2006

During 2005-2006, nine measles virus (MV) genotypes were identified throughout the World Health Organization European Region. All major epidemics were associated with genotypes D4, D6, and B3. Other genotypes (B2, D5, D8, D9, G2, and H1) were only found in limited numbers of cases after importation from other continents. The genetic diversity of endemic D6 strains was low; genotypes C2 and D7, circulating in Europe until recent years, were no longer identified. The transmission chains of several indigenous MV strains may thus have been interrupted by enhanced vaccination. However, multiple importations from Africa and Asia and virus introduction into highly mobile and unvaccinated communities caused a massive spread of D4 and B3 strains throughout much of the region. Thus, despite the reduction of endemic MV circulation, importation of MV from other continents caused prolonged circulation and large outbreaks after their introduction into unvaccinated and highly mobile communities

Genetic variability and mRNA editing frequencies of the phosphoprotein genes of wild-type measles viruses.

The sequences of the nucleoprotein (N) and hemagglutinin (H) genes are routinely used for molecular epidemiologic studies of measles virus (MV). However, the amount of genetic diversity contained in other genes of MV has not been thoroughly evaluated. In this report, the nucleotide sequences of the phosphoprotein (P) genes from 34 wild-type strains representing 15 genotypes of MV were analyzed and found to be almost as variable as the H genes but less variable than the N genes. Deduced amino acid sequences of the three proteins encoded by the P gene, P, V and C, demonstrated considerably higher variability than the H proteins. Phylogenetic analysis showed the same tree topography for the P gene sequences as previously seen for the N and H genes. RNA editing of P gene transcripts affects the relative ratios of P and V proteins, which may have consequences for pathogenicity. Wild-type isolates produced more transcripts with more than one G insertion; however, there was no significant difference in the use of P and V open reading frames, suggesting that the relative amounts of P and V proteins in infected cells would be similar for both vaccine and wild-type strains

The first Russian strategic study of pharmacotherapy for rheumatoid arthritis (REMARCA)

The international recommendations «Treat to target» (T2T) underline the greatest importance of treatment strategy for the success of treating rheumatoid arthritis (RA). Evaluation of the efficiency of this approach obviously requires special strategic studies with an adaptive design, which substantially differ from classical randomized clinical trials and are much closer to clinical practice. To date, there are only single publications on the practical application of the T2T recommendations, there is a problem in the choice of effectiveness criteria and there are a number of other important problems associated with the introduction of these recommendations. The Russian study REMARCA is to answer these questions. Its design focuses on the practical adaptation of the T2T strategy to treat patients with earlyand extended-stage active RA who have poor prognostic factors, by using subcutaneous methotrexate and genetically engineered biological agents (GEBA). Preliminary analysis shows that therapy according to the REMARCA protocol is successful in the majority of patients. The high rate of low RA activity and remission has been achieved during subcutaneous methotrexate monotherapy. The patients who need GEBA to be incorporated may be initially more resistant to therapy. The patients with early RA have better chances of successful T2T therapy than those with extended-stage RA

Comparative analysis of Cd and Zn impacts on root distribution and morphology of Lolium perenne and Trifolium repens: implications for phytostabilization

Backgrounds and aims The phytostabilization potential of plants is a direct function of their root systems. An experimental design was developed to investigate the impact of Cd and Zn on the root distribution and morphology of Lolium perenne and Trifolium repens. Methods Seedlings were transplanted into columns filled with washed quartz and irrigated daily with Cdor Zn-containing nutrient solutions during 1 month. Root biomass, root length density (RLD) and diameter were subsequently quantified as a function of depth. Pot experiments were also performed to quantify metal, lignin and structural polysaccharides concentrations as well as cell viability. Results Lolium perenne accumulated Cd and Zn in the roots whereas T. repens was unable to restrict heavy metal translocation. Cadmium and Zn reduced rooting depth and RLDbut induced thick shoot-borne roots in L. perenne. Cd-induced root swelling was related to lignification occurring in the exodermis and parenchyma of central cylinder. Hemicelluloses and lignin did not play a key role in root metal retention. Cadmium slightly reduced mean root cell viability whereas Zn increased this parameter in comparison to Cd. Conclusions Even though plant species like Lolium perenne and Trifolium repens may appear suitable for a phytostabilization scheme based on their shoot metal tolerance, exposure to toxic heavy metals drastically impairs their root distribution. This could jeopardize the setting up of phytostabilization trials. The metal-induced alterations of root system properties are clearly metal- and speciesspecific. At sites polluted with multiple metals, it is therefore recommended to first test their impact on the root system of multiple plant species so as to select the most appropriate species for each site

Seed Priming of Trifolium repens L. Improved Germination and Early Seedling Growth on Heavy Metal-Contaminated Soil

Abstract Seed priming effects on Trifolium repens were analysed both in Petri dishes and in two soils (one unpolluted soil and a soil polluted with Cd and Zn). Priming treatments were performed with gibberellic acid 0.1 mM at 22 °C during 12 h or with polyethylene glycol (−6.7 MPa) at 10 °C during 72 h. Both priming treatments increased the germination speed and the final germination percentages in the presence of 100 μM CdCl2 or 1 mM ZnSO4. Flow cytometry analysis demonstrated that the positive effect of priming was not related with any advancement of the cell cycle in embryos. Seed imbibition occurred faster for primed seeds than for control seeds. X-ray and electronic microscopy analysis suggested that circular depressions on the seed coat, in addition to tissue detachments inside the seed, could be linked to the higher rate of imbibition. Priming treatments had no significant impact on the behaviour of seedlings cultivated on nonpolluted soil while they improved seedling emergence and growth on polluted soil. The two priming treatments reduced Zn accumulation. Priming with gibberellic acid increased Cd accumulation by young seedlings while priming with polyethylene glycol reduced it. Priming improved the light phase of photosynthesis and strengthened the antioxidant system of stressed seedlings. Optimal priming treatment may thus be recommended as efficient tools to facilitate revegetation of former mining area
