Alcohol dehydrogenases and aldehyde dehydrogenases.
T h e structure, function and evolution of alcohol dehydrogenases and aldehyde dehydrogenases have been studied for several years. Recent progress o n these aspects has been considerable and allows extensive conclusions to be drawn about the relationships and properties of these enzymes. Further aspects have also become available for study, such as the regulation of enzyme expression and the an...
متن کاملFunctional specialization of maize mitochondrial aldehyde dehydrogenases.
The maize (Zea mays) rf2a and rf2b genes both encode homotetrameric aldehyde dehydrogenases (ALDHs). The RF2A protein was shown previously to accumulate in the mitochondria. In vitro import experiments and ALDH assays on mitochondrial extracts from rf2a mutant plants established that the RF2B protein also accumulates in the mitochondria. RNA gel-blot analyses and immunohistolocation experiments...
متن کاملProtection against solar ultraviolet radiation in childhood.
In the last decade, awareness of the harmful effects of solar ultraviolet radiation has increased. Modern lifestyles, outdoor occupations, sports and other activities make total sun avoidance impossible. Children spend more time outdoors than adults and there is compelling evidence that childhood is a particularly vulnerable time for the photocarcinogenic effects of the sun. Sun exposure among ...
متن کاملProtection of DNA during preparative agarose gel electrophoresis against damage induced by ultraviolet light.
Preparative gel electrophoresis of double-stranded DNA usually includes staining the gel with ethidium bromide followed by illumination with ultraviolet (UV-B) light. In this report, DNA isolated from agarose gels was found to be a poor substrate for in vitro transcription, transformation of E. coli and PCR. Inhibition was not caused by enzyme-inhibiting impurities in the agarose gel, but was i...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
