On the basis of radioisotope-incorporation experiments it is suggested that acetyl-CoA, an obligatory intermediate in chloroplast terpenoid biosynthesis, may be formed inmaize from photosynthetically fixed carbon dioxide by the route carbon dioxide --> glycollate -÷ glyoxylate -* glycine --serine --> pyruvate -acetyl-CoA. The proposed route is supported by conventional radioisotope-dilution stu...

radioisotope scanning is very important in evaluation, diagnosis and proper treatment of urinary tract infection (uti) and vesicoureteral reflux (vur) because of high sensitivity of this technique and less radiation dose delivered to the patients. this is a descriptive cross-sectional study to determine the frequency vur in a group of children aged 28 days to 14 years referred to our department...
