Plasmid-mediated and inducible cephalosporinase DHA-2 from Klebsiella pneumoniae.
A Klebsiella pneumoniae strain resistant to cefoxitin and oxyimino-cephalosporins was cultured from a child hospitalized in Paris, France, in 1992. This isolate harboured a beta-lactamase gene located on an approximately 200 kb non-self-transferable plasmid. The beta-lactamase identified, DHA-2, shared 99% amino acid identity with the AmpC enzyme of Morganella morganii. DHA-2 was a point-mutant...
متن کاملC]DHA in phosphatidylcholine
The amount and distribution of [ 13 C]docosahexaenoic acid (DHA) in plasma, platelet, and erythrocyte lipid classes were followed as a function of time (1 to 72 h) in young adults after ingestion of a single dose of [ 13 C]DHA esterified in a phosphatidylcholine (PC), in using gas chromatography combustion–isotope ratio mass spectrometry. [ 13 C]DHA first appeared in plasma non-esterified fatty...
متن کاملDocosahexaenoic Acid (DHA)
Handling & Preparation Instructions This purified fatty acid is liquid at room temperature (oil) and not soluble in water. The product is supplied sterile. It can be solubilized in undiluted serum, ethanol or DMSO. The solubility of Docosahexaenoic acid in ethanol is at least 100 mg/ml. Docosahexaenoic acid has a solubility of 1 mg/ml in a solution of 0.15 M Tris-HCL (pH 8.5). We strongly recom...
متن کاملDoxorubicin Efficacy and Dha
Polyunsaturated fatty acids have been reported to enhance the cytotoxic activity of several anticancer drugs. In the present study, we observed that doxorubicin chemosensitization of breast cancer cell lines by docosahexaenoic acid (DHA, a long chain omega-3 polyunsaturated fatty acid) was cell-line selective, affecting MDA-MB-231 and MCF-7dox (a doxorubicin resistant cell line) but not the par...
متن کاملA maternal erythrocyte DHA content of approximately 6 g% is the DHA status at which intrauterine DHA biomagnifications turns into bioattenuation and postnatal infant DHA equilibrium is reached
PURPOSE Higher long-chain polyunsaturated fatty acids (LCP) in infant compared with maternal lipids at delivery is named biomagnification. The decline of infant and maternal docosahexaenoic acid (DHA) status during lactation in Western countries suggests maternal depletion. We investigated whether biomagnification persists at lifelong high fish intakes and whether the latter prevents a postpart...
