Influence of Storage Conditions on the Stability of Lactide

The objective following of the present study was to investigate the effect of different storage time and conditions on the stability of lactide. In this study the samples of lactide with different purities were stored under three various storage conditions and the compound integration was monitored for a period of 2 weeks. The storage conditions selected were (1) in the desiccator, (2) in the glove box under argon and (3) under ambient atmosphere. The purity of samples was performed on HPLC and Karl Fischer titration during all period of storage. It was shown that the initial purity of the lactide has a significant bearing on the lactide degradation

АКТИВНОСТЬ ПРЕПАРАТА ВЕТОМ 1.23 ПО ОТНОШЕНИЮ К BHV-1 В УСЛОВИЯХ IN VITRO

The search for new preparations effective against viral causative agents in cattle infections is the most important objective of the modern veterinary pharmachology. The virus of infectious bovine rhinotracheitis is widespread on the farms of Siberian region and plays an important part in animal pathology causing big economic losses in the modern livestock-breeding. Antiviral activity of the preparations referred to the group of probiotics is little studied. The antiviral activity of vetom 1.23 against BHV-1 is determined in vitro. The antiviral activity was assessed by reduction of the virus; the assessment was conducted after the virus’s having interacted with vetom 1.23. Graft cell culture of MDBK calf’s kidney was used in the experiment. Avirulent strain ТК-А was used as the virus-test. vetom 1.23 was introduced in the maximal tolerant concentration (62.5 mm3 / cm3 ). The experimental outcomes showed that vetom 1.23 at the dose recommended for the examination and introduced (maximal tolerant concentration) appeared to be little effective against BHV-1, it was poor inhibition in virus multiplication that was observed; the virus titer went down by 0.13–0.5 log10. However, the preparation manifested expressed antivirus effect in higher concentrations.Поиск новых препаратов, эффективных в отношении возбудителей вирусных инфекций крупного рогатого скота, является важной задачей современной ветеринарной фармакологии. Вирус инфекционного ринотрахеита крупного рогатого скота широко распространен в хозяйствах региона Сибири и играет важную роль в патологии животных, причиняя большой экономический ущерб современному животноводству. Противовирусная активность препаратов, относящихся к группе пробиотиков, мало изучена. Определена противовирусная активность ветома 1.23 в отношении BHV-1 in vitro. Оценку противовирусной активности проводили по редукции вируса после его взаимодействия с ветомом 1.23. В эксперименте использовали перевиваемую культуру клеток почки теленка MDBK. В качестве тест-вируса был использован авирулентный штамм ТК-А вируса. Ветом 1.23 вносили в максимальной переносимой концентрации (62,5 мм 3 / см 3 ). Результаты эксперимента показали, что при внесении в рекомендуемой к исследованию дозе (максимальной переносимой концентрации) ветом 1.23 оказался малоэффективным в отношении BHV-1, наблюдалось только слабое ингибирование размножения вируса, титр вируса снижался на 0,13–0,5 log10. Однако в более высоких концентрациях препарат проявлял выраженное противовирусное действие

THE INFLUENCE OF SOCIO-ECONOMIC FACTORS ON THE DEVELOPMENT OF RESIDENTIAL MORTGAGE LENDING (CASE STUDY OF THE ALTAI TERRITORY)

Nowadays the residential mortgage lending is a matter of great importance for the socio-economic development of Russia in the context of providing the majority of people with owner-occupied homes. The problem can be solved by increasing the availability of housing in which case the state support can be hardly overestimated. The paper analyzes the conditions for the organization of the mortgage lending system at the federal and regional levels (by the case study of the Altai Territory). The research findings made it possible to identify the main factors hampering the mortgage development: limited effective demand of the population, high housing prices, low volumes of new housing supply in federal subjects of the Russian Federation, inability to confirm incomes, economic instability, high interest rates, imperfect legislation. Taking into account the obtained results, the authors propose measures aimed at further development of the residential mortgage lending system. Besides, there is a need to raise the awareness of potential borrowers about the possibilities of mortgage programs through awareness-raising activity, publication of interviews with bank executives and the release of methodological literature. The findings concerning the influence of socio-economic factors on the development of the mortgage lending system can be used in the practice of credit institutions to increase the availability of residential mortgage loans
