In vivo "footprints" of the glnA regulatory region under activating conditions demonstrate that the three most upstream activator sequences bind the protein NRI in the cell. Together, protections at these sites span six of seven consecutive major grooves and lie on the same helix face. E sigma 54 protects two major grooves of DNA approximately 60 base pairs downstream at the glnAp2 promoter and...
The chemical oxidant permanganate (MnO(4)(-)) has been shown to effectively transform hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) at both the laboratory and field scales. We treated RDX with MnO(4)(-) with the objective of quantifying the effects of pH and temperature on destruction kinetics and determining reaction rates. A nitrogen mass balance and the distribution of reaction products were...
two rapid, simple, sensitive and cost-effective titrimetric and spectr-ophotometric methods are described for the determination of albendazole (alb) in bulk drug and in pharmaceuticals. in titrimetry (method a), alb is oxidized by a known excess of potassium permanganate (kmno 4 ) in h 2 so 4 medium followed by the determination of unreacted permanganate by titration with ferrous ammonium sulph...
The human epidermis has been studied by electron microscopy following osmium tetroxide and potassium permanganate fixation. An anatomically distinct cell in the human epidermis has been demonstrated with features similar to the melanocyte of the hair bulb described by Barnicot, Birbeck and Cuckow (3). It is dendritic in form and does not contain tonofilaments. "Intercellular bridges" are not fo...
