چکیده

A globulin fraction, isolated from black beans (Phaseolus vulgaris), was resistant to hydrolysis by pepsin, trypsin, chymotrypsin, papain, ficin, hurain, and subtilisin. After denaturation of the globulin by heat or urea, only slight hydrolysis by enzymes could be detected. The activity of all seven proteinases on their respective substrates was inhibited by the bean globulin. Preincubation of enzyme and globulin enhanced the inhibitory effect. When heat denatured, insoluble globulin was stirred with papain, proteolytic activity was diminished.

Measuring Economic Efficiency of Kidney Bean Production using Non-Discretionary Data Envelopment Analysis

Efficient use of assets in agriculture is a goal for policy-makers and farmers. Agricultural input resources are scarce therefore optimum use of inputs in different agricultural operations is important. Mathematical programming technique such as data envelopment analysis (DEA) is a well-known approach for estimation efficiency of agricultural DMUs. In this study, efficiency of kidney bean produ...

Relationship between post-transplant lymphoproliferative disorder and Anti-Thymocyte Globulin or Anti-Lymphocyte Globulin

 Abstract Background: Lymphoproliferative disorders are among the most serious and potentially fatal complications of chronic immunosuppression in kidney transplant recipients. The principle risk factors for development of PTLD are the degree of overall immunosuppression and the EBV serostatus of the recipient. In this study, the risk of PTLD in kidney transplant recipients who received Anti- L...
