Mesoporous silica SBA-15 was synthesized using P123 as surfactant and functionalized with (3-chloropropyl) triethoxysilane. For the first time, the composite of THPP-SBA-15 was prepared using incorporation of tetrakis(4-hydroxyphenyl)porphyrin in functionalized SBA-15. The materials were characterized by BET, SEM, XRD, FT-IR, DRS, and UV–Vis spectroscopy techniques. The synthesized composite wa...

BACKGROUND The fifth Millennium Development Goal target for 90% of births in low and middle income countries to have a skilled birth attendant (SBA) by 2015 will not be met. In response to this, policy has focused on increasing SBA access. However, reducing maternal mortality also requires policies to prevent deaths among women giving birth unattended. We aimed to generate estimates of the abso...

Novel organic-inorganic mesoporous luminescent hybrid material N, N'-bis(salicylidene)-thiocarbohydrazide (BSTC-SBA-15) has been obtained by co-condensation of tetraethyl orthosilicate and the organosilane in the presence of Pluronic P123 surfactant as a template. N,N'-bis(salicylidene)-thiocarbohydrazide (BSTC) grafted to the coupling agent 3-(triethoxysilyl)-propyl isocyanate (TESPIC) was use...

Suprapubic bladder aspiration (SBA) has proved to be a useful and safe method in avoiding contamination when urine samples are taken from children. The following complications have been reported: suprapubic haematoma (Nelson and Peters, 1965), haematuria (Lanier and Daeschner, 1971), and suprapubic abscess (Polnay et al., 1975). A 4i-month-old boy developed a suprapubic abscess after an unsucce...

The amount of soybean agglutinin (SBA) detectable by radioimmunoassay in seeds of resistant cultivars to Phytophthora megasperma var. sojae was approximately twice that of susceptible cultivars. SBA was preferentially released at earlier times (6-9 hours) and in higher amounts in the imbibate from resistant cultivars as compared to susceptible cultivars. The lectin in the imbibate was immunolog...

The voltammetric detection of soybean agglutinin (SBA) was investigated on the basis of an interaction between the lectin and a sugar. Because galactose and lactose combined with SBA, the sugars were labeled by a Schiff base with an electroactive daunomycin. After the labeled sugar and SBA were mixed, measurements were carried out by voltammetry. When SBA-sugar binding occurs, a part of daunomy...

This study was developed to provide further information on the intestinal barrier permeability and the tight junction protein expression in weaned piglets fed with different levels of soybean agglutinin (SBA). Twenty-five weaned crossbred barrows (Duroc × Landrace × Yorkshire) were selected and randomly allotted to five groups, each group with five replicates. The piglets in the control group w...

BACKGROUND Antibodies to factor H (fH)-binding protein (fHBP), a meningococcal vaccine antigen, activate classical complement pathway serum bactericidal activity (SBA) and block binding of the complement inhibitor fH. METHODS To understand these 2 functions in protection, we investigated the interactions of human complement and 2 anti-fHBP monoclonal antibodies (MAbs) with encapsulated Neisse...

We report the first synthesis of titanium nitride (TiN) nanoparticles inside the nanoscale channels of mesoporous silica SBA-15. The TiN precursor, Ti(NMe(2))(4) in toluene, was incorporated into the methyl group-modified channels of the SBA-15 powder. The functionalization of pore surfaces with methyl groups generates hydrophobic surfaces that facilitate impregnation with Ti(NMe(2))(4) and min...
