Basic management principles of the formation of consumer loyalty to brands of regional companies

The problem of forming of consumer loyalty to companies that implement market activity in the regions of the Russian Federation on the scale of small and medium business is investigated. Due to the fact that such business structures do not have the opportunity to compete with large international corporations, they should identify their vector of development with a focus on the consumer, understanding that the formation of loyalty is a very important element of ensuring a stable market position. It is noted that the managers need to work towards improving the quality of not only products, but also implemented management measures in a number of areas. The customer satisfaction is an indicator of achieving a match between the subjectively expected value of the product to the potential consumer and the actual value obtained as a result of the experience of its acquisition and consumption. Thus, only in the case of positive consumer experience can the formation of loyal attitude. A list of basic practice-oriented principles that allow to attract customers, to form a loyal attitude to the company and products has been presented. It is determined that the formation of loyalty is not a one-time marketing campaign, but a complex work of a cohesive team of employees under the guidance of an effective manager. Their effective work, implemented on a permanent basis, will ensure the strengthening of the market position of the brand of the regional business structure. The presented principles will help managers working on the scale of small and medium-sized businesses to form and implement their own strategies to ensure the competitiveness of the company and the demand for products in modern turbulent times, which in turn will contribute to a positive impact on the development of the regional economy of our country

Influence of single amino acid substitutions in the hemagglutinin on the antigenic and receptor-binding properties of influenza virus B/Florida/04/2006 of Yamagata-like evolutionary lineage

Influenza A and B viruses use sialylated oligosaccharide chains expressed on the surface of a host cell as the cell entry receptors. The type of the bond between sialic acid (SA) and the neighboring galactose residue (Gal) is one of the main characteristics that define the type of receptor. Influenza viruses recognize SAα2-3Gal- or SAα2-6Gal-structures on the surface of the cells. Influenza A viruses of avian origin bind α2-3-sialylated glycans, while the human strains bind preferentially α2-6-sialylated ones. However, the receptor-binding specificity of influenza B viruses has not been characterized sufficiently so far. In this study, we selected the escape mutants of influenza B/Florida/04/2006 strain (Yamagata-like lineage) using monoclonal antibodies (mAb) to hemagglutinin (HA). The analysis of the amino acid sequences of mAb-induced escape mutants revealed the single amino acid substitutions 40Tyr→His, 85His→Tyr, 202Asn→Lys and 242Ser→Arg in 10F4-, 8Н11-, 8Н3- and 9А3-induced HA variants, correspondingly. It was shown that the single amino acid substitutions 202Asn→Lys and 242Ser→Arg alter the receptor-binding specificity of the influenza B virus. These findings are important for the understanding of the influence of individual amino acid residues in HA on the receptor-binding properties of influenza B Yamagata-like lineage viruses and allow us to predict the possible ways of their evolution.Influenza A and B viruses use sialylated oligosaccharide chains expressed on the surface of a host cell as the cell entry receptors.

Retrospective trial of long acting analogues detemir and degludec usage in children and adolescents to overcome glucose variability caused by dawn phenomenon and reverse dawn phenomenon

Backgraund: Children with type 1 diabetes mellitus (T1DM) need more insulin late in the evening (reverse dawn phenomenon (RDP)), and adolescents need more insulin yearly in the morning (dawn phenomenon (DP)); these cause blood glucose variability. Modern long acting insulin analogues allow to achieve satisfactory glycemic control.Aims: To study the characteristics of insulin therapy in children and adolescents with T1DM using insulin analogues detemir and degludec to overcome blood glucose variability caused by DP and RDP in different age periods.Materials and methods: We analyzed medical documents of 200 patients using detemir, admitted to pediatric endocrinology department in 2013–2019, at mean age 9.0 years (5.4; 13.0), with T1DM for 1.3 years (0.5; 3.0); and medical documents of 50 patients switched to degludec in 2018–2019 at mean age 12.0 years (10.5; 14.5) with T1DM for 3.0 years (1.5; 6.0). Before degludec they were on intensive insulin therapy with glargine (22), detemir (26), or insulin pump (2); 16 patients (32%) presented with clinical characteristics of DP, and 5 (10%) — RDP.Results: 67 children of 108 (62%) aged 1–9 years had redistribution of detemir doses to daytime; 58 adolescents of 92 (63%) aged 10–17 лет — to nighttime. Patients switched to degludec demonstrated decrease in HbA1с from 8.7% (7.8; 9.9) to 8.0% (7.4; 9.0) (р<0.001); fasting blood glucose from 9.8 mmol/l (7.4; 11.7) to 7.7 mmol/l (6.4; 8.6) (р<0.001); within-day variability from 35.2% (31.6; 40.9) to 23.5% (19.7; 28.6) (р<0.001); daily insulin dose from 0.98 U/kg/day (0.82; 1.14) to 0.87 U/kg/day (0.75; 1.07) (р=0.002). Sub-groups of patients with DP and RDP demonstrated decrease in fasting blood glucose (from 11.5 mmol/l (9.8; 13.8) to 7.5 mmol/l (6.6; 9.1) (р<0.001)), and late evening blood glucose (from 11.0 mmol/l (10.2; 11.2) to 8.0 mmol/l (6.7; 9.5) (р= 0.03)) correspondently. Achieved levels of glycemic control did not differ between sub-groups of patients initially using glargine or detemir.Conclusions: Compensation of T1DM may be complicated due to DP and RDP. Switching to degludec allowed to achieve better glycemic control and lowering of blood glucose variability caused by DP and DRP

Dual tRNA mimicry in the Cricket Paralysis Virus IRES uncovers an unexpected similarity with the Hepatitis C Virus IRES

Co-opting the cellular machinery for protein production is a compulsory requirement for viruses. The Cricket Paralysis Virus employs an Internal Ribosomal Entry Site (CrPV-IRES) to express its structural genes in the late stage of infection. Ribosome hijacking is achieved by a sophisticated use of molecular mimicry to tRNA and mRNA, employed to manipulate intrinsically dynamic components of the ribosome. Binding and translocation through the ribosome is required for this IRES to initiate translation. We report two structures, solved by single particle electron cryo-microscopy (cryoEM), of a double translocated CrPV-IRES with aminoacyl-tRNA in the peptidyl site (P site) of the ribosome. CrPV-IRES adopts a previously unseen conformation, mimicking the acceptor stem of a canonical E site tRNA. The structures suggest a mechanism for the positioning of the first aminoacyl-tRNA shared with the distantly related Hepatitis C Virus IRES

Development of the cell-ELISA test for the subtype identification of circulating influenza A(H1) and A(H3) viruses

The sensitive version of cell-ELISA was developed for the subtype-specific differentiation of current influenza A(H1N1)pdm09 and A(H3N2) viruses that are circulating in the human population. This method is based on the estimation of virus reproduction in infected MDCK cells. The detection step of this method is an interaction of the subtype-specific monoclonal antibodies (mAbs) with the viral hemagglutinin (НА) molecule. The influenza A virus strains, isolated in the 2014 epidemic season, were used to validate this method.It was shown that when using mAbs # 1/ # 2 or # 4 at a concentration of 10-15 µg/ml, the developed variant of cell-ELISA was able to detect НА protein synthesized in the infected cells of influenza A(H3N2) and A(H1N1)pdm09 viruses, respectively.The developed method can be used for the identification of modern influenza A viruses with low hemagglutination activity, which is not possible by the conventional hemagglutination inhibition test.The sensitive version of cell-ELISA was developed for the subtype-specific differentiation of current influenza A(H1N1)pdm09 and A(H3N2) viruses that are circulating in the human population.
