Analysis of hemocyte parameters in Pacific oysters, Crassostrea gigas, reared in the field — Comparison of hatchery diploids and diploids from natural beds
Provedor de dados: 5

Internal defence mechanisms of bivalves include the hemocytes which assume several functions. Relationships exist between environmental factors, physiological state of oysters, defence system and pathogens. Hatchery oysters are more and more produced and reared in the field. The characteristics and particularly the defence system of these animals are poorly documented. In this context, two field trials were carried out from May to September 2002 and from April to July 2003 in order to monitor hemocyte parameters of diploid oysters from natural beds and hatchery-produced diploid oysters using flow cytometry. Several hemocyte parameters (cell mortality, granulocyte percentage, phagocytosis, esterase and peroxidase activities) were monitored. For both oyster...

Differential esterase activity in aerial and root tissues from 6as DHR wheat lines after phytohormonal treatments
Provedor de dados: 46
Autores: Tacaliti,M.S; Tocho,E; Castro,A.M.
Activity of aerial and root esterases in wheat DHR lines of chromosome 6AS was tested. Different patterns were found after applying phytohormone treatments that mimic stress conditions. Ethylene treated plants showed the lowest aerial and root weights; also, the smallest foliar area, in conjunction with absence of esterase activity in more than half of the lines, was observed. Additional studies will contribute to clarify the key role of ET in the expression of defense related genes.

Isolation of natural inhibitors of papain obtained from Carica papaya latex
Provedor de dados: 52
Autores: Monti,Rubens; Contiero,Jonas; Goulart,Antonio José.
Studies were carried out to natural papain inhibitor from papaya latex. Fresh latex from green fruits of Carica papaya was collected and immediately transported in ice bath to the lab, from which three fractions with inhibitor effect of esterase papain activity were isolated by latex dialysis, Sephadex G-25 gel filtration and ionic exchange chromatography in SP-Sephadex C-25. The isolated fractions, identified as inhibitors I and II, showed a negative reaction with ninhydrin; however, the fraction identified as P-III showed positive reaction with ninhydrin. Kinetics data showed non-competitive inhibition (inhibitor I) and uncompetitive (inhibitors II and P-III).
