Two separate species of Ureaplasma have been identified that infect humans: Ureaplasma parvum and Ureaplasma urealyticum. Most notably, these bacteria lack a cell wall and are the leading infectious organism associated with infection-related induction of preterm birth. Fourteen separate representative prototype bacterial strains, called serovars, are largely differentiated by the sequence of re...

Thirty-nine derivatives of 7,12-dimethylbenz(a)anthracene (DMBA) were tested for mutagenicity towards Salmonella typhimurium strain TA100 in the presence of activating enzymes. The compounds tested included four sets of 3,4-, 5,6-, 8,9-, and 10,11-diols: those of DMBA, its 7and 12-hydroxymethyl derivatives, and the 7,12-dihydroxymethyl derivative. Several phenolic derivatives and formyl and car...

The reaction of lead(II) acetate and 3-methyl-benzoic acid (MBA) in aqueous solution yielded the title polymer, [Pb(C(8)H(7)O(2))(2)(H(2)O)](n). The asymmetric unit contains two Pb(II) atoms, four MBA ligands and two water mol-ecules. Each Pb(II) cation is hepta-coordinated and chelated by four carboxyl-ate O atoms from two MBA ligands. The Pb atoms are bridged through the carboxyl-ate O atoms ...

Abstracts of invited talks blancos of invited talks blanco A moving balls approximation method for a class of smooth constrained minimization Alfred Auslender Université de Lyon, France We introduce a new algorithm for a class of smooth constrained minimization problems which is an iterative scheme that generates a sequence of feasible points that approximates the constraints set by a sequence ...

Some pH responsive polymeric matrix of Linseed (Linum usitatissimum), L. hydrogel (LSH) was prepared by free radical polymerization using potassium persulfate (KPS) as an initiator, N,N-methylene bisacrylamide (MBA) as a crosslinker, acrylic acid (AA) and methacrylic acid (MAA) as monomers; while ketoprofen was used as a model drug. Different formulations of LSH-co-AA and LSH-co-MAA were formul...
