Luminescence functionalization of the ordered mesoporous SBA-15 silica is realized by depositing a CeF3: Eu3+ phosphor layer on its surface (denoted as CeF3: Eu3+/SBA-15/IS, CeF3: Eu3+/SBA-15/SI and CeF3: Eu3+/SBA-15/SS) using three different methods, which are reaction in situ (I-S), solution impregnation (S-I) and solid phase grinding synthesis (S-S), respectively. The structure, morphology, ...
Antibacterial tests of Ag/SBA-15 from petung bamboo leaf ash against Escherichia coli were carried out. Modification SBA-15 with Ag was conducted using the wet impregnation method while antibacterial test out by well diffusion and disc various concentrations Ag/SBA-15. The has a surface area 143 m2/g, pore diameter 8.4 nm volume 0.35 cm3/g. SAXS pattern /SBA-15 showed 3 typical peaks in 0o -2...
Adolescent vaccination is now considered the key factor for offering direct protection against meningococcal disease but also for reducing carriage and transmission and, in this way, establishing herd protection. This study estimated age-dependent patterns in functional meningococcal serogroup C (MenC) antibody kinetics after primary MenC conjugate (MenCC) vaccination in adolescents. Serum samp...
The silylation of SBA-15 enhances the reducibility of cobalt oxides on a SBA-15 supported cobalt catalyst, and consequently increases the catalytic activity for Fischer-Tropsch synthesis of hydrocarbons from syngas and selectivity for longer chain products.
Encapsulated meningococci are complement sensitive only in the presence of bactericidal antibodies by yet-unexplored mechanisms. The objective of this study was to investigate the involvement of major bacterial surface constituents on complement activation and membrane attack complex (MAC) formation on serogroup B meningococci in the presence or absence of antibody-dependent serum bactericidal ...
OBJECTIVE The objective of this study was to seek validity evidence for simulation-based assessments (SBA) of paramedics by asking to what extent the measurements obtained in SBA of clinical competence are associated with measurements obtained in actual paramedic contexts, with real patients. METHODS This prospective observational study involved analyzing the assessment of paramedic trainees ...
A new selective group A streptococcus agar (ssA) (BBL Microbiology Systems, Cockeysville, Md.) was evaluated for the recovery and direct plate identification of group A beta-hemolytic streptococci (GABHS) in comparison with sheep blood agar (SBA). A total of 265 GABHS were recovered from 1,116 throat swab specimens on both media, with detection rates of 98.9 and 91.7% for ssA and SBA, respectiv...
BACKGROUND Following mass vaccination campaigns in the African meningitis belt with group A meningococcal conjugate vaccine, MenAfriVac (PsA-TT), disease due to group A meningococci has nearly disappeared. Antibody persistence in healthy African toddlers was investigated. METHODS African children vaccinated at 12-23 months of age with PsA-TT were followed for evaluation of antibody persistenc...
Composite molecular sieves, FAU/SBA-15, having core-shell structure were synthesized. The synthesized composite sieves were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), pyrolysis fourier transform infrared (Py-FTIR) spectroscopy, temperature programmed desorption spectra (NH3-...
BACKGROUND Antimicrobial susceptibility testing (AST) of Clostridium difficile is increasingly important because of the rise in resistant strains. The standard medium for the AST of C. difficile is supplemented Brucella agar (sBA), but we found that the growth of C. difficile on sBA was not optimal. Because active growth is critical for reliable AST, we developed a new, modified C. difficile (m...
