Journal ArticleDOI
Distribution of polychlorinated biphenyls, organochlorine pesticides and polybrominated diphenyl ethers in human umbilical cord serum, maternal serum and milk from Wielkopolska region, Poland
Kamila Jaraczewska,Janina Lulek,Adrian Covaci,Stefan Voorspoels,Agnieszka Kaluba-Skotarczak,Krzysztof Drews,Paul Schepens +6 more
TL;DR: Results found in the investigated group are at the low end of the concentration range measured in Europe, with BDE 47 being always the most abundant PBDE congener and, together with Bde 153, being present in all samples.
Journal ArticleDOI
Folic acid-conjugated core/shell ZnS:Mn/ZnS quantum dots as targeted probes for two photon fluorescence imaging of cancer cells.
Malgorzata Geszke,Marek Murias,Lavinia Balan,Ghouti Medjahdi,Jarosław Korczyński,Michał Moritz,Janina Lulek,Raphaël Schneider +7 more
TL;DR: The folate receptor-mediated delivery of folic acid-conjugated ZnS:Mn/ZnS QDs was demonstrated using confocal microscopy with biphotonic excitation, and Bare and folate- Conjugated QDs exhibit only weak cytotoxicity towards folate receptors-positive T47D cancer cells and MCF-7 cells, used as a reference, after 72h incubation.
Journal ArticleDOI
Copper- or manganese-doped ZnS quantum dots as fluorescent probes for detecting folic acid in aqueous media
Małgorzata Geszke-Moritz,Małgorzata Geszke-Moritz,Gilles Clavier,Janina Lulek,Raphaël Schneider +4 more
TL;DR: In this paper, a quenching mechanism was proposed to detect folic acid concentrations as low as 11μm, thus affording a very sensitive system for the sensing of this biologically active molecule in aqueous solution.
Journal ArticleDOI
Thioglycerol-capped Mn-doped ZnS quantum dot bioconjugates as efficient two-photon fluorescent nano-probes for bioimaging
Małgorzata Geszke-Moritz,Małgorzata Geszke-Moritz,Hanna Piotrowska,Marek Murias,Lavinia Balan,Michał Moritz,Janina Lulek,Raphaël Schneider +7 more
TL;DR: Water-dispersible 1-thioglycerol (TG)-capped Mn-doped ZnS quantum dots were prepared in aqueous solution using the nucleation-doping strategy and folate receptor mediated cellular uptake of FA-functionalized dots is proven via confocal and two-photon imaging.
Journal ArticleDOI
Recent progress in continuous and semi-continuous processing of solid oral dosage forms: a review
TL;DR: The attempt to connect the primary and secondary production steps proves that development of continuously operating lines is possible and a mind-set change is needed to be able to face, and fully assess, the advantages and disadvantages of switching from batch to continuous mode production.
