Schlievert et al. recently reported that the increased number of cases of toxic shock syndrome (TSS) observed by their surveillance group over the last 4 years in the Minneapolis-St. Paul metropolitan area is consistent with Centers for Disease Control and Prevention findings of an 18% increase in the incidence of TSS from 2002 to 2003 (3). He wisely cautioned medical practitioners and women us...

Nanoscale dynamic heterogeneities in synthetic polymer solutions are detected using super-resolution optical microscopy. To this end, we map concentration fluctuations in polystyrene-toluene solutions with spatial resolution below the diffraction limit, focusing on critical fluctuations near the polymer overlap concentration, c*. Two-photon super-resolution microscopy was adapted to be applicab...

The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...

The aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates SPION and Gemcitabine in PLGA±PEG to form multifunctional drug delivery system. For this aim, super paramagnetic iron oxide nanoparticles (SPIONs) were synthesized and encapsulated simultaneously with Gemcitabine (Gem) in PLGA±PEG copolymers via W/O/W double emulsification method. Optimum size and enca...

Electrically conducting super-macroporous polymer/carbon nanotubes (CNTs) composites have been fabricated with the aid of cryogenic treatment. CNTs are selectively deposited onto the inner surface of interconnected polymer walls surrounding large air-filled pores. The present concept provides highly conducting nanocomposites at a very low nanotubes content.
