PURPOSE Milk contains free and bound oligo- and heteropolisaccharides, which protect newborns against pathogens and have nutritional value. N-acetyl-beta-D-hexosaminidase (HEX), the most active lysosomal exoglycosidase, modify and degrade oligo- and heteropolysaccharides. The objective of our study was to determine HEX activity and isoenzymes A and B in the progression of lactation. MATERIAL ...

Since the discovery that bovine prothrombin when dissolved in 25% sodium citrate is autocatalytically converted to thrombin (2), several reviews have appeared which summarize the many chemical and biological changes occurring during this transformation (3-5). Recently the findings that poly-L-lysine, as well as a number of polyamino acids, initiates prothrombin activation (6) have suggested the...

ed sulfur radical cation (SETA)(S.-.S)+ was observed after pulse irradiation of solutions contain1 50K ing high concentration of SETA at pH 6. This reveals another interesting feature that indicates that hydroxysulfuranyl radicals (SETA)>S--OHare not converted efficiently into (SETA)(S.. S)+ but they would rather convert into the 380(-nm species. The intensity of absorption bands and the decay ...

PURPOSE It is a known fact that age is a strong predictor of adverse events in acute coronary syndrome (ACS). In this context, the main risk factor in elderly patients, ie, frailty syndrome, gains special importance. The availability of tools to identify frail people is relevant for both research and clinical purposes. The purpose of this study was to investigate the correlation of a scale for ...

This paper is an extension of the talk I gave at the International Conference on Non-Commutative Rings, Group Rings, Diagram Algebras and Applications at the University of Madras in December 2006. It discusses certain techniques used to prove the existence of free subgroups in linear groups and in the unit group of integral group rings of finite groups. Its main focus is recent joint work with ...
