https://www.selleckchem.com/products/Fulvestrant.html The analysis of current data concerning the use of oral nutrition supplements (ONS) in cancer patients has been performed. The aim of the research is improving the effectiveness of medical nutrition in cancer patients by clarifying terms, definitions, developing an applied classification of ONS formulas and outlining the basic approaches for their use. MATERIAL AND METHODS Using the keywords «cancer», «oral nutritional supplements», and «siping», the literature was searched in such databases as eLIBRARY (elibrary.ru) and MEDLINE (ncbi.nlm.nih.gov) in Russian and English. RESULTS AND DISCUSSION The definition of this type of nutritional support has been given. The applied classification of ONS formulas has been made. Depending on the energy and protein content, presence of some specific nutrients, osmolarity, nitrogen/non-protein kilocalories ratio and viscosity, they were divided into 3 groups. For the initial assessment of nutritional status of the cancer patient, the European society for medical oncology scale (ESMO, 2008) is the most appropriate. Emphasis is placed on the importance of maintaining physical activity. CONCLUSION An approximate algorithm of ONS prescribing in oncology has been formulated.

The aim was to obtain and characterize in vitro food protein hydrolysates to evaluate their use in specialized foods with reduced potential allergenicity. MATERIAL AND METHODS Whey protein concentrate (WPC) and chicken egg protein (CEP) and enzymes such as pancreatin and alkalase have been used. Proteolysis of proteins was carried out in an FA-10 fermenter for 3 hours at an enzyme substrate ratio of 150 in dry matter, at optimal pH and temperature for pancreatin and alkalase. Enzymes were inactivated
