    Abstract Background: The human chromosome 19q13.32 is a gene rich region and has been associated with multiple phenotypes, including late onset Alzheimer's disease (LOAD) and other age-related conditions.
    Objective: Here we developed the first humanized mouse model that contains the entire TOMM40 and APOE genes with all intronic and intergenic sequences including the upstream and downstream regions. Thus, the mouse model carries the human TOMM40 and APOE genes and their intact regulatory sequences.
    Methods: We generated the APOE-TOMM40 humanized mouse model in which the entire mouse region was replaced with the human (h)APOE-TOMM40 loci including their upstream and downstream flanking regulatory sequences using recombineering technologies. We then measured the expression of the human TOMM40 and APOE genes in the mice brain, liver, and spleen tissues using TaqMan based mRNA expression assays.
    Results: We investigated the effects of the '523' polyT genotype (S/S or VL/VL), sex, and age on the human TOMM40- and APOE-mRNAs expression levels using our new humanized mouse model. The analysis revealed tissue specific and shared effects of the '523' polyT genotype, sex, and age on the regulation of the human TOMM40 and APOE genes. Noteworthy, the regulatory effect of the '523' polyT genotype was observed for all studied organs.
    Conclusion: The model offers new opportunities for basic science, translational, and preclinical drug discovery studies focused on the APOE genomic region in relation to LOAD and other conditions in adulthood.

    Abstract Das Projekt Gruene Chemie zielt darauf ab, bereits SchuelerInnen fuer eine neue 'gruene Chemie' im Hinblick auf umweltvertraegliche und nachhaltige Produktionsverfahren zu begeistern, indem sie in aktuelle wissenschaftliche Arbeiten an der TU Wien eingebunden werden sollen. Ziel ist es, sie nachhaltig fuer Naturwissenschaften im Allgemeinen und chemische Disziplinen im Speziellen gewinnen zu koennen. Dazu ist ein umfassendes Programm aus experimentellen Arbeiten, Auswertung der Versuche, Verfassung von Berichten und schliesslich Kommunikation der Resultate und Themenfelder geplant. Dabei sollen insbesondere auch LehrerInnen eingebunden werden, um die neuen Entwicklungen spaeter im eigenen Lehrbetrieb weitervermitteln zu koennen. Die einzelnen Individualprojekte sind thematisch zwischen mehreren beteiligten Forschungsgruppen angesiedelt und sollen kooperativ betreut werden.

    Abstract We perform a systematic study of the α-particle excitation from its ground state 0_{1}^{+} to the 0_{2}^{+} resonance. The so-called monopole transition form factor is investigated via an electron scattering experiment in a broad Q^{2} range (from 0.5 to 5.0  fm^{-2}). The precision of the new data dramatically supersedes that of older sets of data, each covering only a portion of the Q^{2} range. The new data allow the determination of two coefficients in a low-momentum expansion, leading to a new puzzle. By confronting experiment to state-of-the-art theoretical calculations, we observe that modern nuclear forces, including those derived within chiral effective field theory that are well tested on a variety of observables, fail to reproduce the excitation of the α particle.

    Abstract Transcriptional and immunocytological characterization of thymic epithelial (TE) cell line TE750 shows that these cells, like primary TE cell cultures, transcribe alpha-3, alpha-5 and beta-4 acetylcholine receptor (AcChR) subunit genes while expressing cortical, medullary and epithelial differentiation thymic markers. Incubation of TE750 cells with nicotine decreases cell adherence and growth as measured through direct cytological observation and nucleic acid quantification, respectively. Physostigmine, a traditional cholinesterase inhibitor that also activates nicotinic AcChRs, reproduces the effects of nicotine. Strengthening the hypothesis that cholinergic receptors mediate the effects of physostigmine, acetylcholinesterase (AcChase) activity is not detected in TE750 cells. Also, like thymocytes, TE750 cells express choline acetyltransferase (ChAT), indicating that the natural transmitter AcCh can be produced locally within the thymic parenchyma. Taken together these findings indicate that TE750 cells in culture represent a suitable in vitro system for the analysis of cholinergic mechanisms operational in the thymic epithelium.

    Abstract A solid-state nanopore can electrophoretically capture a DNA molecule and pull it through in a folded configuration. The resulting ionic current signal indicates where along its length the DNA was captured. A statistical study using an 8-nm-wide nanopore reveals a strong bias favoring the capture of molecules near their ends. A theoretical model shows that bias to be a consequence of configurational entropy rather than a search by the polymer for an energetically favorable configuration. We also quantified the fluctuations and length dependence of the speed of simultaneously translocating polymer segments from our study of folded DNA configurations.
