Nucleotides with a dye attached to the terminal phosphate with four or more phosphates (tetra- or pentaphosphates) are superior substrates than the corresponding triphosphates for DNA and RNA polymerases. When fluorogenic dyes are directly attached to the terminal phosphate, they can be released by the action of polymerase and alkaline phosphatase. The released dye changes color and fluorescenc...
Sensitized photooxidation of imidazoles in aqueous solution and in the presence of inorganic phosphate afforded organic phosphates with yields up to 30%. The major phosphorylated product of oxidation of 2-methylimidazole was isolated and identified as the monophosphate of 4,5-dihydroxy-2-methyl-imidazoline with pKa values of 2.0, 5.2, and 9.8. The compound is energy rich in aqueous solution and...
Studying soil phosphorus fractions is useful in understanding soil pedogenesis as well as soil fertility. In this reseach, 20 soil samples were taken from different depths of 0-30 and 30-60 cm of upper-slope, mid-slope and lower-slope positions of four toposequences in arid (Jei and Ziar in Isfahan) and semiarid (Farokhshahr and Shahrekord) regions. In each toposequence, the soil depth was re...
OBJECTIVE To determine the frequency of Osteomalacia and biochemical abnormalities in patients with hip fracture who presented at our Institution. METHODS All patients with operatively treated hip fractures (Aga Khan University Hospital, Karachi from June 1996 to June 2001) were included. The total number of patients was 168 with 59 males and 109 females. Eighty nine patients presented with i...
An improved technology for the local treatment of industrial wastewater a meat processing plant is proposed intensification cleaning processes and an increase in efficiency according to indicators: HSC, SPAR, phosphates, ammonium nitrogen, fats, obtaining purified water accordance with regulatory requirements at discharge into city sewer. According technology, after existing grease trap concent...
Zan lateritic horizon is located about 25 km southeast of Damavand, Tehran Province. This horizon developed as stratiform in lower part of shales and sandstones of Shemshak Formation (Jurassic). Mineralogical investigations show that diaspore, hematite, goethite, anatase, and kaolinite are the principal minerals of this horizon accompanied by lesser amounts of accessory minerals like boehmite, ...
Ceramides (Cer) comprise the major constituent of sphingolipids in the epidermis and are known to play diverse roles in the outermost layers of the skin including water retention and provision of a physical barrier. In addition, they can be hydrolyzed into free sphingoid bases such as C(18) sphingosine (SO) and C(18) sphinganine (SA) or can be further metabolized to C(18) So-1-phosphate (S1P) a...
Phosphorus (P) from biomass can cause operational problems in thermal conversion processes. In order to explore the release mechanism of P gas phase, carbothermic reduction meta-, pyro-, and orthophosphates ash elements commonly found biomass; sodium, potassium, magnesium, calcium was investigated. Mixtures each phosphate activated carbon were heated 1135 °C a laboratory-scale reactor, with CO ...
This study aims to quantify the synergistic effect of Ni2+ and Mn2+ ions on capacitive performance oxide, hydroxide phosphate electrodes in alkaline electrolytes. Three types phases containing both nickel manganese a ratio one-to-one were selected due their stability media: oxides with ilmenite spinel structures (NiMnO3 Ni1.5Mn1.5O4); hydroxides layered (?-Ni1/2Mn1/2(OH)2); phosphates olivine m...
