Background: Infection with human immune deficiency virus (HIV) or hepatitis B virus (HBV) is one of the health problems in blood transfusion science. This study was conducted in shiraz for determination of the rate of HIV positivity in blood donors during the years 1998-2002. Materials and Methods: This cross-sectional descriptive study was conducted on 615790 blood donors. All samples were scr...
Abstract Background and objectives: Hepatitis C virus (HCV), Human immuno deficiency virus (HIV) and Hepatitis B Virus (HBV) are the three main agents of Communicable disorders transmitted by blood transfusion. The survey of these virus-caused infections in Blood donors can display epidemiology of infections in province and be useful for evaluating donors’ health. The aim of this study wa...
Sharing structural and mechanistic properties with the dinitrogen-fixing enzyme nitrogenase, dark-operative protochlorophyllide oxidoreductase (DPOR) participates in biosynthesis of bacteriochlorophyll, subsequently enabling photosynthesis by photosynthetic bacteria. In contrast to light-dependent POR, electron transfer DPOR is coupled hydrolysis adenosine triphosphate for two-electron stereose...
Anammox coupling with nitrate reduction under various electron donors was studied using sludge acclimatized to have anammox and denitrification activities. Due to a deficiency in electron donors for NO(3)(-) reduction, anammox activity in an inorganic medium containing NO(3)(-) and NH(4)(+) was lower than that in NO(2)(-) and NH(4)(+). Anammox could use NO(2)(-) competitively against denitrifie...
