A homogeneously translucent titanate nanobelt (TNB) suspension was prepared through facile surface modification of pristine TNBs by polymer wrapping with poly(allylamine hydrochloride). The resultant TNB aqueous suspension was found to remain stable for months. The nonlinear optical (NLO) and optical limiting (OL) properties of the TNB suspension were then investigated. We found that the TNB su...

Transfection of suspension cells has proven to be very difficult using conventional methods. Here, we present a simple and time-saving new transfection protocol wherein cell culture plates coated with chicken egg white are seeded with suspension cells prior to transfection. Our results demonstrate that coupling egg white coatings with commercially available transfection reagents leads to high t...

Hydatid disease caused by tapeworm is an increasing public health and socioeconomic concern. In order to enhance the therapeutic efficacy of praziquantel (PZQ) against tapeworm, PZQ-loaded hydrogenated castor oil solid lipid nanoparticle (PZQ-HCO-SLN) suspension was prepared by a hot homogenization and ultrasonication method. The stability of the suspension at 4°C and room temperature was evalu...

In this work, we show a simple experimental procedure to obtain CdTe/CdS (diameterZ3–7 nm) core shell nanocrystals in colloidal suspension. The nanocrystals were characterized by transmission electronic microscopy and powder X-ray diffraction analysis. The optical properties were determined by electronic absorption, excitation and emission spectroscopies and are discussed in terms of chemical c...

We compared nebulised beclomethasone dipropionate suspension against placebo in 16 children with moderately severe asthma in double blind crossover fashion. Three children withdrew due to deterioration while on placebo. Of the remaining 13, eight were better on beclomethasone and five on placebo. These trends in favour of nebulised beclomethasone were not significant and do not suggest that the...

For a 1-connected spectrum E, we study the moduli space of suspension spectra which come equipped with a weak equivalence to E. We construct a spectral sequence converging to the homotopy of the moduli space in positive degrees. In the metastable range, we get a complete homotopical classification of the path components of the moduli space. Our main tool is Goodwillie’s calculus of homotopy fun...

Streptococcus Pneumoniae suspension preparation S. Pneumoniae capsular type 6A (DBL6A) was previously described as a virulent strain (Briles et al., 1992). Hemoculture of mouse second passage isolates were provided by Dr. Denis Martin (ID Biomedical, Quebec, Canada) and a suspension of the provided culture in Todd Hewitt medium supplemented with 0.5% yeast extract (THY) was incubated at 37 o C ...

Film formation of particle/binder/solvent system is of importance in various applications to produce battery, display, electronic components and so on. Because dispersion stability is a crucial issue for defect-free final products, many attempts have been carried out to analyze and control the microstructure of the suspension. In this study, The effect of polymers on dispersion stability and fi...

We conducted an in vivo study to evaluate the anticancer effect and toxicity of fine-powder cisplatin suspended in lipiodol (fCDDP/LPD suspension) after a single administration of three different doses to rats via the intrahepatic artery after transplantation of rat ascites hepatoma cells. The toxicity of the fCDDP/LPD suspension was also assessed in the same protocol in noncancer-bearing rats ...

While posaconazole prophylaxis decreases the risk of invasive fungal infection compared to fluconazole, low bioavailability of the oral-suspension formulation limits its efficacy. A new delayed-release tablet formulation demonstrated an improved pharmacokinetic profile in healthy volunteers. However, serum levels for the two formulations have not been compared in clinical practice. This study c...
