disodium glycyrrhetinic acid hemiphthalaic (gap) was evaluated for developmental toxicity in pregnant nmri mice. gap was administered intrapcritoneally on days s, 9, 10, of gestation at doses of 0, 25, 50 and 75 mg/kg/dav. on gestation day of is, after operational delivery, the fetuses were examined for soft tissue, external and skeletal defects. increased absorptions, dead fetuses, and reduce ...

Choline dihydrogen phosphate has previously been shown to be a good ionic conductor as well as an excellent host for acid doping, leading to high proton conductivities required for e.g., electrochemical devices including proton membrane fuel cells and sensors. A combination of variable-temperature (1)H solid-state NMR and 2D NMR pulse sequences, including (31)P and (13)C CODEX and (1)H BaBa, sh...

Abstract Most soils contain Phosphorus (P) in insoluble compounds as organic and inorganic forms which is unavailable to plants. Furthermore, phosphate solubilizing bacteria (PSB) play an important role converting P a bioavailable form through mineralizing or P. Therefore, this study aims determine the ability of isolate bacterium (PSB), Stenotrophomonas maltophilia solubilize The was isolated ...

: World population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. In recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. In this study, single cell protein production was studied in a batch submerged culture using Aspergillus niger PTCC5012. Experimental design was ...

Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...

By SANFORD LEIKIN AND SAMUEL P. BESSMAN D ISODIUM ETHYLEXEDIAMINE TETRAACETATE (EDTA) has beets known for some time to prolong coagulation in vitro.’3 During the course of treatment of seven patiemits for lead ititoxication with disodium calcium EDTA, we noted mio hemorrhagic mamiifestations.4’ However, Wishimisky6 described hypoprothrombimsemia appearing its a patiemit treated with disodium ca...

Enzymes of the reductive pentose phosphate cycle including ribulose-diphosphate carboxylase, ribulose-5-phosphate kinase, ribose-5-phosphate isomerase, aldolase, glyceraldehyde-3-phosphate dehydrogenase and alkaline fructose-1,6-diphos-phatase were shown to be present in autotrophically grown Rhodospirillum rubrum. Enzyme levels were measured in this organism grown photo- and dark heterotrophic...

Glycerol is one of the few carbon sources that can be utilized by Mycoplasma pneumoniae. Glycerol metabolism involves uptake by facilitated diffusion, phosphorylation, and the oxidation of glycerol 3-phosphate to dihydroxyacetone phosphate, a glycolytic intermediate. We have analyzed the expression of the genes involved in glycerol metabolism and observed constitutive expression irrespective of...

Per(6-guanidino-6-deoxy)-cyclodextrins , and are novel derivatives, resulting from homogeneous introduction of the guanidino group at the primary side of alpha-, beta- and gamma-cyclodextrins. The products were obtained from the corresponding amino derivatives, as direct guanidinylation of the known bromo-cyclodextrins provided mixtures. The new compounds were fully characterized by NMR spectro...
