Post-Communist Russia: Emerging Political Forces And Their Coalition Patterns

Melville,Andrei,Fedorov,Yuri 서울대학교 러시아연구소 1993 러시아연구 Vol.3 No.-

Формирование новых политических сил и динамику их коаличий в посткоммунистической россии нельзя понять по прямой аналогии с политическими процессами, характерными для других стран, в том числе для (классических) (латиноамериканских и южноевропейских случаев становления демократических режимов. То, что происходнт сегодня в России, никак не укладывается не только в саму схему перехода от авторитарнзма к демократии, но и в традиционные категории (либерализма) и (консерватизма), (левых) и (правых) и т.п. Уяснение сути процессов формирования и динамики политических сил и их коалиций в России на нынешнем витке её исторических обстоятельств и социальных условий, в которых происходят эти процессы, культурных, национальных и иных тралиций, влияющих на них, словом - всего того уникального конктекста, который и формирует сегодняшнюю российскую политику.

Butyric acid and prospects for creation of new medicines based on its derivatives: a literature review

Lyudmila K. Gerunova,Taras V. Gerunov,Lydia G. P'yanova,Alexander V. Lavrenov,Anna V. Sedanova,Maria S. Delyagina,Yuri N. Fedorov,Natalia V. Kornienko,Yana O. Kryuchek,Anna A. Tarasenko The Korean Society of Veterinary Science 2024 Journal of Veterinary Science Vol.25 No.2

The widespread use of antimicrobials causes antibiotic resistance in bacteria. The use of butyric acid and its derivatives is an alternative tactic. This review summarizes the literature on the role of butyric acid in the body and provides further prospects for the clinical use of its derivatives and delivery methods to the animal body. Thus far, there is evidence confirming the vital role of butyric acid in the body and the effectiveness of its derivatives when used as animal medicines and growth stimulants. Butyric acid salts stimulate immunomodulatory activity by reducing microbial colonization of the intestine and suppressing inflammation. Extraintestinal effects occur against the background of hemoglobinopathy, hypercholesterolemia, insulin resistance, and cerebral ischemia. Butyric acid derivatives inhibit histone deacetylase. Aberrant histone deacetylase activity is associated with the development of certain types of cancer in humans. Feed additives containing butyric acid salts or tributyrin are used widely in animal husbandry. They improve the functional status of the intestine and accelerate animal growth and development. On the other hand, high concentrations of butyric acid stimulate the apoptosis of epithelial cells and disrupt the intestinal barrier function. This review highlights the biological activity and the mechanism of action of butyric acid, its salts, and esters, revealing their role in the treatment of various animal and human diseases. This paper also discussed the possibility of using butyric acid and its derivatives as surface modifiers of enterosorbents to obtain new drugs with bifunctional action.
