متن کاملRegulation of oxidative stress and lipid peroxidation in PTU induced mice, treated with Pyrroloquinoline quinone (PQQ)
Hitherto unknown effects of Pyrroloquinoline quinone (PQQ) in 6-n-propyl-2-thiouracil (PTU)induced oxidative stress and lipid peroxidation were investigated in adult mice. Animals received either PTU (0.05% in drinking water) alone for 5 weeks or PTU + three different concentrations of PQQ, after which alterations in tissue lipid peroxidation (LPO) and in enzymatic activities of superoxide dism...
متن کاملOne-electron Reduction of Pyrroloquinoline Quinone (pqq), in Aqueous Solutions: a Pulse Radiolysis Study
One electron reduction of Pyrroloquinoline quinone (PQQ) was studied using pulse radiolysis technique. Reactions of hydrated electron, H atom, radical and superoxide radicals produced very similar transient species. The radicals did not show decay in few milliseconds. The one-electron reduction potential of PQQ was determined at pH 7 using both methyl viologen and benzyl viologen couples and wa...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
The Life History of Pyrroloquinoline Quinone (PQQ): A Versatile Molecule with Novel Impacts on Living Systems
Pyrroloquinoline quinone (4, 5-dihydro(4), 5-dioxo(1) H-pyrroloquinoline-2,7, 9 tricarboxylic acid) being a three ortho cyclic quinone substitutes the role of a redox-cofactor for various bacterial dehydrogenases such as methanol, ethanol and glucose dehydrogenases [1-6] also termed as methotaxin [7]. PQQ structure prediction shows that it has been originated from tyrosine and Glutamic-acid [8]...
