Here, three isomeric methylpyridinium alkynylanthracenes 1op were evaluated as sensitizers for PDT. Upon irradiation with blue or green light, all three compounds show the ability to initiate strand breaks of plasmid DNA. The mayor species responsible for cleavage is singlet oxygen (O-1(2)) as confirmed by scavenging reagents. Only isomers 1m and 1p can be incorporated into HeLa cells, whereas isomer 1o cannot permeate through the membrane. While isomer 1m targets the cell nucleus, isomer 1p assembles in the cellular cytoplasm and impacts the cellular integrity. This is in accordance with a moderate toxicity of 1p in the dark, whereas 1m exhibits no dark toxicity. Both isomers are suitable as PDT reagents, with a CC50 of 3 mu m and 75 nm, for 1p and 1m, respectively. Thus, derivative 1m, which can be easily synthesized, becomes an interesting candidate for cancer therapy.}, language = {en} } @article{RoggenbuckGoihlHanacketal.2017, author = {Roggenbuck, Dirk and Goihl, Alexander and Hanack, Katja and Holzloehner, Pamela and Hentschel, Christian and Veiczi, Miklos and Schierack, Peter and Reinhold, Dirk and Schulz, Hans-Ulrich}, title = {Serological diagnosis and prognosis of severe acute pancreatitis by analysis of serum glycoprotein 2}, series = {Clinical chemistry and laboratory medicine : journal of the Forum of the European Societies of Clinical Chemistry - the European Branch of the International Federation of Clinical Chemistry and Laboratory Medicine}, volume = {55}, journal = {Clinical chemistry and laboratory medicine : journal of the Forum of the European Societies of Clinical Chemistry - the European Branch of the International Federation of Clinical Chemistry and Laboratory Medicine}, publisher = {De Gruyter}, address = {Berlin}, issn = {1434-6621}, doi = {10.1515/cclm-2016-0797}, pages = {854 -- 864}, year = {2017}, abstract = {To better understand emerging adults' perceptions of family interactions and value transmission to the next generation, we examined Hmong American emerging adults' reflections on their parents' parenting. Participants discussed what parenting practices they would do differently and others they hoped to emulate with their future adolescent children. Thirty Hmong American emerging adults (18-25 years; M = 21.2 years; 50\% female) participated in interviews that focused retrospectively on the parent-adolescent relationship. Results revealed that emerging adults wanted to parent differently in three ways: less pressure about education, fewer restrictions, and more open communication. Emerging adults imagined being a similar parent in four ways: promoting education, promoting life values, giving guidance, and offering love and support. The findings highlight parenting practices that Hmong American emerging adults plan on transmitting (and not transmitting) to their own children, offering a glimpse into the type of parents the emerging adults may become.}, language = {en} }
