Biological and chemical pruning wound protectants reduce infection of grapevine trunk disease pathogens

fungal pathogens associated with grapevine trunk diseases in iran

during 2004–2007 various own rooted vineyards were inspected to study the fungi associated with vine trunk diseases in iran. samples from declining vines showing yellowing and reduced growth and different symptoms in wood, including browning of the wood, necrosis, brown and black streaking and white rot were collected. fungal isolations were made from affected tissues onto malt extract agar (me...

Diversity of Fungal Trunk Pathogens Associated with Grapevine Dieback of Grapevine in Algeria

A significant reduction in vine production has recently been recorded in several vine regions in Algeria due to the death (total or partial) of many vines and to the pulling of many vineyards that had showed too many symptoms of decline. This study was conducted during spring 2010 2012 to detect the responsible agents for this disease. Samples of grapevine wood were collected in five grapevine ...

Perioperative normothermia to reduce the incidence of surgical-wound infection and shorten hospitalization. Study of Wound Infection and Temperature Group.

BACKGROUND Mild perioperative hypothermia, which is common during major surgery, may promote surgical-wound infection by triggering thermoregulatory vasoconstriction, which decreases subcutaneous oxygen tension. Reduced levels of oxygen in tissue impair oxidative killing by neutrophils and decrease the strength of the healing wound by reducing the deposition of collagen. Hypothermia also direct...

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 ...
