Disease relevance of Oxybispropanol

• Hydrophobic interaction chromatography of Chromobacterium viscosum lipase on polypropylene glycol immobilised on Sepharose [1].
• Previous work has shown that when the bacterium Stenotrophomonas maltophilia is grown on polypropylene glycol, different dye-linked polypropylene glycol dehydrogenase (PPG-DH) activities are induced during growth [2].
• Contact sensitization to dipropylene glycol in an eczema population [3].
• Occupational allergic contact dermatitis from UV-cured lacquer containing dipropylene glycol diacrylate [4].
• Three of them (Sphingobium sp. strain EK-1, Sphingopyxis macrogoltabida strain EY-1, and Pseudomonas sp. strain PE-2) utilized both PEG and polypropylene glycol (PPG) as a sole carbon source [5].

High impact information on Oxybispropanol

• We have engineered two related sphingomonads, the dioxin-degrading S. wittichii RW1 and the polypropylene glycol-degrading S. subarctica IFO 16058(T), to incorporate this superchannel into their cell membranes [6].
• Glutamine synthetase from nodule cytosol has been purified by a procedure involving fractionation with protamine sulphate, ammonium sulphate and polypropylene glycol, chromatography on DEAE-Bio-Gel A and Bio-Gel A-5m and affinity chromatography on glutamate-agarose columns [7].
• The porous layer adsorbent is formed on capillary walls by the hydrolysis of aluminum alkoxide in the presence of polypropylene glycol (PPG) and HCl [8].
• The chromatographic purification of Chromobacterium viscosum lipase by hydrophobic interaction chromatography on Sepharose CL-6B modified by covalent immobilisation of 1,4-butanediol diglycidyl ether, polyethylene glycol and polypropylene glycol was also compared [1].
• MDI is an industrial chemical for which skin decontamination, using traditional soap and water and nontraditional polypropylene glycol, a polyglycol-based cleanser (PG-C), and corn oil were all tried in vivo on the rhesus monkey, over 8 h [9].

Biological context of Oxybispropanol

• The PPG/PGPMS networks exhibit low fibrinogen adsorption and low platelet activation [10].
• Toxicology and carcinogenesis studies of dipropylene glycol in rats and mice [11].
• Whether PPG dehydrogenase (PPG-DH) has wide stereo- and enantioselective substrate specificity towards PPG isomers or not must await further purification [12].
• Dipropylene glycol monomethyl ether: a 13-week inhalation toxicity study in rats and rabbits [13].

Anatomical context of Oxybispropanol

• Hydrophobic interactions contributed to the retention of the blood cells on the PPG-bonded agarose columns [14].
• The affinity of surface blood cells to bonded PEG and PPG stationary phases is apparently selective, and granulocytes and lymphocytes are more strongly retained on the column than erythrocytes and platelets [14].
• METHOD: Primary and permanent teeth with dentin caries were stained with Caries Check (CC), containing 1% acid red in polypropylene glycol (MW=300) or Caries Detector (CD), containing 1% acid red in propylene glycol (MW=76) [15].
• The hydrophobic interactions between the hydrophobic region on the cell surface membrane and the bonded PEG, PPG phases is probably the main factor affecting the retention of lymphocytes and granulocytes [16].

Associations of Oxybispropanol with other chemical compounds

• This review describes the surface-affinity chromatography of human peripheral blood cells on polyethylene glycol (PEG) and polypropylene glycol (PPG) chemically bonded columns [14].
• The relaxation dynamics of dipropylene glycol and tripropylene glycol (nPG-n=2,3) water solutions on the nPG-rich side has been studied by broadband dielectric spectroscopy and differential scanning calorimetry in the temperature range of 130-280 K [17].
• Best results were obtained with a polymer formulation containing a high molecular weight fatty acid and 3 microcapsule formulations containing lanolin, gum arabic, gelatin, tannic acid, stearic acid, polypropylene glycol, water, and a commercial lotion in the microcapsule and carrier fractions [18].

Gene context of Oxybispropanol

• Broadband dielectric measurements of polypropylene glycol of molecular weight M(w)=400 g / mol (PPG 400) were carried out at ambient pressure over the wide temperature range from 123 to 353 K [19].

Analytical, diagnostic and therapeutic context of Oxybispropanol

• Using 15O-butanol positron emission tomography (PET), we measured regional cerebral blood flow changes in five healthy young women during exposure to androstadienone, a putative human pheromone, as well as pleasant (gamma-methyl-ionone), unpleasant (methyl-thio-butanoate), and neutral (dipropylene glycol; vehicle compound) odours [20].
• An irritancy patch test was performed on 56 controls, using BIT in concentrations of 0.002% and 0.05% in aqueous dipropylene glycol (Proxel GXL) and 0.1% in pet [21].
