آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولBrief Communication: French Maritime Pine Bark Extract (Pinus Pinaster) and Its Ophthalmic Use
Bark extract of Pinus pinaster has a long history of medicinal use and is available commercially as herbal dietary supplement with proprietary name pycnogenol. It is used as a food supplement to overcome many degenerative conditions and has been ascribed a very diverse clinical pharmacology [1]. Although there are many potential uses for Pycnogenol, the well-studied use is for improving vascula...
متن کاملEffective gene dispersal and female reproductive success in Mediterranean maritime pine (Pinus pinaster Aiton).
Understanding population-scale processes that affect allele frequency changes across generations is a long-standing interest in genetic, ecological and evolutionary research. In particular, individual differences in female reproductive success and the spatial scale of gene flow considerably affect evolutionary change and patterns of local selection. In this study, a recently developed maximum-l...
متن کاملPhenolic content and antioxidant property of the bark extracts of Ziziphus mucronata Willd. subsp. mucronata Willd
BACKGROUND Several plants traditionally used in treatment of a variety of infections in South Africa are reported in ethnobotanical surveys. Many of these plants including Ziziphus mucronata subsp. mucronata lack scientific reports to support their medicinal importance. METHODS The antioxidant activities and phenolic contents of the acetone, ethanol and aqueous extracts of the stems of Z. muc...
متن کاملThe Role of Population Origin and Microenvironment in Seedling Emergence and Early Survival in Mediterranean Maritime Pine (Pinus pinaster Aiton)
Understanding tree recruitment is needed to forecast future forest distribution. Many studies have reported the relevant ecological factors that affect recruitment success in trees, but the potential for genetic-based differences in recruitment has often been neglected. In this study, we established a semi-natural reciprocal sowing experiment to test for local adaptation and microenvironment ef...
