Formation of a photorespiration-based CO2-concentrating mechanism in C3-C4 intermediate plants is seen as a prerequisite for the evolution of C4 photosynthesis, but it is not known how efficient this mechanism is. Here, using in vivo Rubisco carboxylation-to-oxygenation ratios as a proxy to assess relative intraplastidial CO2 levels is suggested. Such ratios were determined for the C3-C4 interm...
Hepatocytes which had been isolated from the livers of Charles River rats were cultured in vitro. The cells were shown to synthesize albumin and the complement components C4, C2, C3 and B. Pulse-label studies with [35S]methionine showed that C4 and C3 were synthesized as single polypeptide chains. Pro-C4 did not appear to be converted into the plasma form of C4 intracellularly, whereas cell lys...
C4 photosynthesis affords higher photosynthetic carbon conversion efficiency than C3 photosynthesis and it therefore represents an attractive target for engineering efforts aiming to improve crop productivity. To this end, blueprints are required that reflect C4 metabolism as closely as possible. Such blueprints have been derived from comparative transcriptome analyses of C3 species with relate...
Background: Exercise training is associated with improved health outcomes in many populations. It is assumed that exercise activities in the rheumatoid arthritis (RA) population may be reduced as a result of symptoms of the disease. The purpose of this study is survey of long-term effect of regular exercise on inflammatory changes in the RA population. Methods: In a randomized control trial, 30...
The human hepatoma-derived cell line, HepG2, synthesized and secreted functional complement proteins C1r, C1s, C2, C3, C4, C5, factor B, C1 inhibitor, C3b inactivator, a small amount of C6, and trace amounts of C8; but failed to produce detectable C1q, C7, or C9. Immunochemically, C2, C3, C4, C5, and B were isolated from culture medium as proteins with molecular sizes and subunit structures ide...
زمینه و هدف: هدف از مطالعه حاضر بررسی تأثیر شنیدن دو نوع تلاوت قرآن به روش ترتیل یا مجلسی بر مقدارفاکتور های سیستم ایمنی مثلiga, igm, igg, c3, c4 ,wbc در انسان بود. مواد و روش ها : این مطالعه نیمه تجربی روی 60 نفر دانشجوی داوطلب در دانشگاه علوم پزشکی سبزوار انجام گرفت. افراد به طور تصادفی به دو گروه تقسیم شدند. گروه اوّل به تلاوت نوع ترتیل و گروه دوم به تلاوت نوع مجلسی به مدّت 20 دقیقه گوش دادند...
background: idiopathic anterior uveitis is an anterior segment inflammation in which a detailed medical history, general and ocular physical examination is not associated with any defined clinical syndrome. alterations in immune system parameters have been reported in patients with idiopathic posterior uveitis; however no data on the role of immune system in idiopathic anterior uveitis has yet ...
Leaves of C4 crops usually have higher radiation, water and nitrogen use efficiencies compared to the C3 species. Engineering C4 traits into C3 crops has been proposed as one of the most promising ways to repeal the biomass yield ceiling. To better understand the function of C4 photosynthesis, and to identify candidate genes that are associated with the C4 pathways, a comparative transcription ...
