glucose-6-phosphate dehydrogenase is an essential enzyme to cell growth. its deficiency of enzyme plays an important role in senescence and death signaling. also, it is actually the most common clinically important enzyme defect, not only in hematology, but also among all human known diseases. clinical consequences of enzyme deficiency are: neonatal hyperbilirubinemia, acute hemolytic anemia, a...

A rapid electrochemical technique was developed to determine 8-Hydroxyquinoline (8HQ). In the current study, the anionic surfactant Sodium lauryl sulfate (SLS) was immobilized on the multi-walled carbon nanotube (MWCNT) paste surface for the fabrication of electrode to detect 8HQ in phosphate buffer solution (PBS) of pH 7.0. The response of SLS modified carbon nanotube paste electrode (SLSMCNTP...

Space is an unforgiving environment – one of harshest known to mankind. Yet, space is far less understood than other service environments in which DOD systems operate. It has been known to limit the useful life of satellites, with 20 to 25% of all mission failures being attributed to the effects of the space environment.[1] Since access to space is so costly, materials and components must funct...

background colorectal cancer (crc) is the third most common cancer in iran and its early detection is necessary. this study is based on perception of people in the east of iran toward crc screening.   methods in a cross-sectional study, 1060 randomly selected individuals who referred to razavi hospital of mashhad, iran, between september the 1st, 2012 and february the 28th, 2013 as patients or ...

This paper gives a comprehensive review about the most recent progress in graphene and graphene oxide based electrochemical sensors and biosensors.  Graphene, emerging as a true 2-dimensional material, has received increasing attention due to its unique physicochemical properties (high surface area, excellent conductivity, high mechanical strength, and ease of functionalization and mass product...
