If a second dose of varicella vaccine were to be recommended, MMRV could be used to administer a routine second dose of M-M-RII with the added advantage of boosting varicella-zoster virus (VZV) antibody titers. Subjects 12-23 months of age received a single injection of 1 of 3 lots of an MMRV vaccine (ProQuad) containing high, middle or low VZV potency, or VARIVAX given concomitantly with M-M-RII. Recipients of MMRV received a second injection of MMRV approximately 90 days later. We enrolled 1559 subjects in the study. Antibody response rates to VZV 6 weeks after 1 injection of high potency MMRV (88.6%) or 2 injections of MMRV of any varicella potency (99.7-100%) were similar to the response rates after concomitant administration of M-M-RII and VARIVAX (93.1%). The second injection of MMRV boosted VZV antibody titers. Antibody responses to measles, mumps and rubella were >or=98%, similar to the control, after 1 or 2 injections of MMRV. MMRV was generally well-tolerated during the 42 days after vaccination. One injection of high potency MMRV resulted in antibody responses to the 4 vaccine components equivalent to those found after concomitant administration of M-M-RII and VARIVAX. A second injection of MMRV resulted in a significant boost in VZV antibody. This boost may translate into enhanced immunogenicity against varicella, which is known to correlate with increased protection.

Healthy 2-month-old infants (N=1008) were randomized to the two groups. Following dose 1, there was no significant difference between the groups in the incidence of fever >101.3 degrees F. After each dose, the incidence of any fever (> or =100.4 degrees F) was significantly higher in the Combination Vaccine Group. The rate of fever >103.1 degrees F was < or =1.4% in both groups after any of the doses. Medical advice visits for fever were infrequent in both groups (< or =1.2%). DTaP-HepB-IPV was safe and well tolerated when coadministered with PCV and Hib.

ABSTRACT The monovalent rhenium compounds ReBr(CO)3(3,3′-dimethyl-2,2′-biquinoline) (I) and ReBr(... more ABSTRACT The monovalent rhenium compounds ReBr(CO)3(3,3′-dimethyl-2,2′-biquinoline) (I) and ReBr(CO)5 (II) could be used as catalysts in styrene polymerization after activation with diphenylzinc (Ph2Zn) and methylaluminoxane (MAO). The catalytic activity shown by the I-Ph2Zn-MAO system was dependent on the molar ratio between the components and the temperature of polymerization. Non stereoregular polystyrene (PS) was obtained under all experimental conditions. The resulting PS gave multimodal GPC traces suggesting the presence of different species capable of polymerizing styrene, possibly species resulting from MAO alone, I-Ph2Zn and I-Ph2Zn-MAO systems.

The X-ray diffraction shows an irregular tetrahedral coordination around of metal in both monometallic complexes with little differences in Cu–N distances and N–Cu–N bite angles than involved the indazole ligand between two complexes. The proton spectra show a different variation in chemical shift relative to free ligand, which was discussed by steric and magnetic current effects of another coordinated ligand. The differences in the energy of metal-to ligand-charge-transfer (MLCT) and in redox potentials to CuII/CuI process in both complexes show the notorious influence of the phosphine which by back-donating effect, modified the energy of HOMO orbital centered in Cu atom. The coordinative and redox stability in solution was established for several days in non-coordinating solvent. However in acetonitrile the ligand substitution is very fast.

The compounds were characterized physically and spectroscopically (Elemental Analysis, Conductivity, Cyclic Voltammetry, IR-FT, RMN-H and UV-Visible.) the results are consistent with the [Re(CO)32,2´-biquinoline)(4,4´-bipiridine](CF3SO3) and RuCl(CO)2(2,2´-biquinoline) formulation for the monometallic precursor complexes and with the [(CO)3(2,2´-biquinoline)Re(4,4´-bipiridine)RuCl(CO)2(2,2´-biquinoline)](CF3SO3)2formulation for the bimetallic complexe.
