in this study, isophthalic acid-zirconium(iv) nanocomposite has been prepared from zirconyl nitrate pentahydrate and potassium iodide, with isophthalic acid, (c8h6o4=benzene-1,3-dicarboxylic acid) as a ligand, via sonochemical method in ethylene glycol and methanol as solvents. the crystalline tetragonal zro2 has been produced by thermal decomposition of isophthalic acid-zirconium(iv) nanocompo...

background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...

background: precursor b-acute lymphoblastic leukemia (precursor b-all) oc-curs due to the uncontrolled proliferation of b-lymphoid precursors arrested at a par-ticular stage of b-cell development. precursor-b-all is classified mainly into pro-b-all, common-all and pre-b-all. the common acute lymphoblastic antigen cd10 is the marker for common-all. objective: this study was aimed to examine the ...

Aluminosilicate gel precursor having mullite composition was synthesized from inorganic salts of aluminum and silicon by employing the sol-gel method. Chemical analysis, surface area and bulk density measurements were performed to characterize the dried gel. The course of the mullitization was examined by FT-IR analysis which confirmed the diphasic nature of the gel. ...

Surface ozone (Surface O3)is a secondary pollutant and there are only limited studies on ozone in South India. Studies have revealed a strong correlation between higher ozone levels and warmer days. Surface O3 along with its precursors like NO2, CO and CH4 are being measured at Kanyakumari (8.0780° N, 77.5410° E), TamilNadu, India and in this paper we present the summer time variation of ozone ...

1. Staphylococci activated by rapid growth in the presence of excess O(2) and subsequently brought to a resting state by storage in Locke's solution at 5 degrees C. produce a significant rise in [phage] when added to phage-containing solutions. 2. For satisfactory activation the staphylococci require a period of active growth in the presence of oxygen. Activation proceeds best on the acid side ...
