Hexagonally ordered mesoporous silica materials MCM-41 and SBA-15 have been synthesized and loaded with Ag nanoparticles, utilizing both chemical synthesis and ultrashort pulsed laser ablation in liquid. In laser ablation, a silver target, immersed in aqueous suspension of ordered mesoporous silica SBA-15, was irradiated by ultra-short laser pulses to generate silver nanoparticles. For comparis...

An inorganic-organic hybrid fluorescence chemosensor (DA/SBA-15) was prepared by covalent immobilization of a dansylamide derivative into the channels of mesoporous silica material SBA-15 via (3-aminopropyl)triethoxysilane (APTES) groups. The primary hexagonally ordered mesoporous structure of SBA-15 was preserved after the grafting procedure. Fluorescence characterization shows that the obtain...

A new selective medium (CNA-P) that reduces or eliminates the inhibitory activity of bacteriocin-producing Streptococcus salivarius against beta-hemolytic streptococci has been developed and compared with sheep blood agar (SBA) for the sensitive detection of small numbers of beta-hemolytic streptococci in clinical specimens. CNA-P has as its basis a commercial medium (Difco Columbia CNA agar) s...

In UK medical schools, five-option single-best answer (SBA) questions are the most widely accepted format of summative knowledge assessment. However, writing SBA questions with four effective incorrect options is difficult and time consuming, and consequently, many SBAs contain a high frequency of implausible distractors. Previous research has suggested that fewer than five-options could hence ...

BACKGROUND Availability of a Skilled Birth Attendant (SBA) during childbirth is a key indicator for MDG5 and a strategy for reducing maternal and neonatal mortality in Africa. There is limited information on how SBAs and their functions are defined. The aim of this study was to map the cadres of health providers considered SBAs in Sub Saharan Africa (SSA); to describe which signal functions of ...

Introduction Small bowel adenocarcinoma is a rare malignancy associated with a poor prognosis, and there is (removed ‘a’) weak evidence of effective treatment. Case presentation We report on a 72-year-old female who developed a peritoneal metastasis from recurrent small bowel adenocarcinoma after curative resection and adjuvant chemotherapy with S-1 and polysaccharide K. Subsequently, no sign o...

Hexagonal mesoporous silica (SBA-15) was prepared and then functionalized by(3-mercaptopropyl)trimethoxysilane. The obtained 3-mercaptopropyl functionalized SBA-15 (SBA-Pr-SH) was then oxidized using H2O2 in methanol under an acidic condition to give sulfonic acid functionalized mesoporous silica (SBA-Pr-SO3H). Th...
