Epstein-Barr virus-specific cytotoxic T lymphocyte clones were shown to be an effective target for their own lysis when incubated in the presence of their specific epitopes but not in the presence of irrelevant epitopes. The mode of cell killing appeared to be by apoptosis and was prevented by previously described inhibitors of the process. Degranulation, as measured by serine esterase activity...

Background and Purpose: Annually affecting millions of women, vulvovaginal candidiasis (VVC) is commonly described by signs and symptoms of vulvovaginal inflammation in the presence of Candida species. Today, the detection of the virulence factors plays a major role in the understanding of pathogenesis of candidiasis and helps produce new anticandidial drugs to improve its treatment efficiency....

Bile salt-stimulated cholesterol esterase is synthesized in the pancreatic acinar cells and is released into the intestinal lumen where it catalyzes cholesterol absorption. In the current study, Caco-2 cells were used as an in vitro model to study the interaction between the pancreatic cholesterol esterase with intestinal cells. Results showed that addition of increasing concentrations of chole...

HE existence in natural populations of a protein polymorphism involving Ttwo forms of a nonspecific esterase has been established in Drosophila mlamgaster (WRIGHT 1961, 1963). The two forms of the esterase, Esterase 6, are distinguishable by their different electrophoretic mobilities in starch gel, Esterase 6" migrating more rapidly toward the anode than Esterase 6s. The inheritance of these tw...

Objective: Alcea genus belongs to Malvaceae family and this is represented by 85 taxa in the world 21 Flora of Turkey.The flowers contain plenty mucilage are used for treatment respiratory diseases such as asthma cough.Alcea dissecta known ‘Govik, Hiro, Hero’ Turkey, leaves species have been asthma,injury, colds, gastrointestinal Turkey. To best our knowledge, there no report on effect extracti...

A comparison was made of the esterase and activator activities of the various activated forms of human plasminogen and their streptokinase complexes with Nalpha-Cbz-L-lysine-p-nitrophenyl ester as the substrate. The steady state kinetic properties of Glu- and Lys-plasmins, and Glu- and Lys-plasminogen-streptokinase complexes were identical, while the Lys-plasmin-streptokinase complex showed a 2...

The simultaneous extraction and enzymatic hydrolysis of sinapine from a mustard residue was designed for the recovery sinapic acid, high value-added phenolic acid. An initial screening allowed identification sinapoyl esterase activities in commercial cocktails (Depol 740 L, Ultraflo XL, Deltazym VR AC-100, Pectinase-PL “Amano”) mono-enzymatic solution rumen feruloyl esterase. These were not ver...

Interest in the distribution of choline esterase activity between the cells and plasma dates back a dozen years or more, but relatively little investigation has been carried out. In 1928 Galehr and Plattner (1), using a biological assay method, found that there was more choline esterase activity in human blood cells than in serum, and their finding was confirmed by Matthes (2) in 1930. The este...

1. Liver tissue showing fatty degeneration obtained from animals poisoned with phosphorus or chloroform contains a decreased amount of esterase. 2. The serum of animals poisoned with phosphorus or chloroform has a high esterase activity. 3. The increased amount of esterase in the serum is not derived from the disintegrating liver cells as the esterase in the blood of the hepatic vein is less th...
