  abstract  = {This paper seeks to unify two major theories of moral judgment: Kohlberg's stage theory and Anderson's moral information integration theory. Subjects were told about thoughts of actors in Kohlberg's classic altruistic Heinz dilemma and in a new egoistical dilemma. These actors's thoughts represented Kohlberg's stages I (Personal Risk) and IV (Societal Risk) and had three levels, High, Medium, and Low. They were presented singly and in a 3 x 3 integration design. Subjects judged how many months of prison the actor deserved. The data supported the averaging model of moral integration theory, whereas Kohlberg's theory has no way to handle the integration problem. Following this, subjects ranked statements related to Kohlberg's first four stages in a procedure similar to that of Rest (1975). Higher score went with larger effect of Societal Risk as predicted by Kohlberg's theory. But contrary to Kohlberg's theory, no age trends were found. Also strongly contrary to Kohlberg's theory, effects of Personal Risk (Stage I) and Societal Risk (Stage IV) correlated positively.},

  abstract  = {Mittels Laserblitz-Photolyse wurden die Triplettlebenszeiten sowie die L{\"o}schraten der Triplettzust{\"a}nde verschiedener Acetophenonderivate durch dG, 8-oxodG, DNA, molekularen Sauerstoff und die Ketone selbst bestimmt. F{\"u}r AP-OAc, AP und BP wurden Triplettlebensdauern von 7-9 µs gemessen, w{\"a}hrend die Triplettzust{\"a}nde von AP-OH und AP-OtBu aufgrund alpha Spaltung deutlich kurzlebiger waren (ca. 1 µs); die alpha Spaltung konnte EPR-spektroskopisch durch Spinabfangexperimente mit DMPO und TEMPO belegt werden. Im Fall von AP-OMe wurde weder dessen Triplettzustand noch die Bildung von Radikalen detektiert, was auf einer schnell ablaufenden Norrish-Typ-II-Spaltung beruht. Aufgrund dieses photochemischen Verhaltens wurden die Ketone (mit Ausnahme von AP-OMe) in zwei Gruppen klassifiziert, n{\"a}mlich die „Gruppe A"-Ketone (keine Radikalbildung) und die „Gruppe B"-Ketone (Radikalbildner). W{\"a}hrend die „Gruppe A"-Ketone gegen{\"u}ber niedrigen Konzentrationen von DNA (62.5 µM) inaktiv waren, verursachten die bei der Bestrahlung der „Gruppe B"-Ketone generierten Peroxylradikale, neben wenigen direkt induzierten Strangbr{\"u}chen, haupts{\"a}chlich die Guaninoxidationsprodukte 8-oxoGua und guanidinfreisetzende Produkte (GRP). Erst wenn die DNA-Konzentration zehnfach erh{\"o}ht wird (625 µM), tritt bei der Photolyse der „Gruppe A"-Ketone auch DNA-Oxidation durch einen Elektronentransfer von der Guaninbase auf das angeregte Keton ein. Ein analoger Konzentrationseffekt wurde auch in der dG-Oxidation beobachtet, bei niedrigen Substratkonzentrationen sind nur die radikalbildenden „Gruppe B"-Ketone aktiv. Die Tatsache, dass in der dG-Oxidation durch die „Gruppe A"-Ketone kein 8-oxodG detektiert wurde, wurde auf dessen effiziente Oxidation durch dG•+-Radikalkationen zur{\"u}ckgef{\"u}hrt. Die „Gruppe B"-Ketone sind in Abwesenheit von O2 gegen{\"u}ber dG und DNA oxidativ inaktiv, da die in der alpha Spaltung generierten kohlenstoffzentrierten Radikale keine Peroxylradikale bilden k{\"o}nnen. Die „Gruppe A"-Ketone sind gegen{\"u}ber DNA in Abwesenheit wie auch in Anwesenheit von Sauerstoff genauso reaktiv, da der Elektronentransfer von DNA zum Keton unabh{\"a}ngig von Sauerstoff ist. Um mechanistische Einblicke in die oxidative DNA-Sch{\"a}digung zu erlangen, wurden photochemische Modellstudien mit dem Nukleosid dG sowie 8-oxodG durchgef{\"u}hrt, wobei zus{\"a}tzlich Spiroiminodihydantoin gebildet wird. Bis vor kurzem wurde die Struktur dieses Oxidationsproduktes als 4-HO-8-oxodG angenommen, dass zuerst in der dG Oxidation mit Singulettsauerstoff (1O2) beobachtet wurde. Weder Spiroiminodihydantoin noch 4 HO-8-oxodG sind als authentische Verbindungen bekannt, so dass eine zweifelsfreie Strukturaufkl{\"a}rung die Bestimmung der Konnektivit{\"a}t der markierten Positionen erforderte. Diese Zuordnung erfolgte mittels eines SELINQUATE-NMR Spektrums, mit dem schl{\"u}ssig die 4 HO-8-oxodG-Struktur ausgeschlossen wurde. Wie alle „Gruppe B"-Ketone sind auch alle „Gruppe A"-Ketone in Abwesenheit von O2 mit Ausnahme von AP-OAc gegen{\"u}ber dG inert. Dies ist ein Beleg daf{\"u}r, dass der Elektronentransferschritt von dG zum Keton in Abwesenheit von Sauerstoff (im Gegensatz zur DNA-Oxidation) reversibel ist und daher keine Oxidation m{\"o}glich ist, wenn die Ketylradikale nicht durch O2 abgefangen werden. Das aus AP-OAc gebildete Ketylradikal besitzt als einziges einen effektiven unimolekularen Deaktivierungsweg, n{\"a}mlich die Acetation-abspaltung, so dass die Reversibilit{\"a}t nicht mehr m{\"o}glich ist.},

  abstract  = {Since the first description of a systematic mis-reaching by Balint in 1909, a reasonable number of patients showing a similar phenomenology, later termed optic ataxia (OA), has been described. However, there is surprising inconsistency regarding the behavioral measures that are used to detect OA in experimental and clinical reports, if the respective measures are reported at all. A typical screening method that was presumably used by most researchers and clinicians, reaching for a target object in the peripheral visual space, has never been evaluated. We developed a set of instructions and evaluation criteria for the scoring of a semi-standardized version of this reaching task. We tested 36 healthy participants, a group of 52 acute and chronic stroke patients, and 24 patients suffering from cerebellar ataxia. We found a high interrater reliability and a moderate test-retest reliability comparable to other clinical instruments in the stroke sample. The calculation of cut-off thresholds based on healthy control and cerebellar patient data showed an unexpected high number of false positives in these samples due to individual outliers that made a considerable number of errors in peripheral reaching. This study provides first empirical data from large control and patient groups for a screening procedure that seems to be widely used but rarely explicitly reported and prepares the grounds for its use as a standard tool for the description of patients who are included in single case or group studies addressing optic ataxia similar to the use of neglect, extinction, or apraxia screening tools.},

  abstract  = {Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose polymerase), and both BRCA1 and BRCA2. In the present study, we have performed a comprehensive analysis of 18 genes involved in BER using a tagging SNP approach in a large series of BRCA1 and BRCA2 mutation carriers. 144 SNPs were analyzed in a two stage study involving 23,463 carriers from the CIMBA consortium (the Consortium of Investigators of Modifiers of BRCA1 and BRCA2). Eleven SNPs showed evidence of association with breast and/or ovarian cancer at p<0.05 in the combined analysis. Four of the five genes for which strongest evidence of association was observed were DNA glycosylases. The strongest evidence was for rs1466785 in the NEIL2 (endonuclease VIII-like 2) gene (HR: 1.09, 95\% CI (1.03-1.16), p = 2.7x10(-3)) for association with breast cancer risk in BRCA2 mutation carriers, and rs2304277 in the OGG1 (8-guanine DNA glycosylase) gene, with ovarian cancer risk in BRCA1 mutation carriers (HR: 1.12 95\% CI: 1.03-1.21, p = 4.8x10(-3)). DNA glycosylases involved in the first steps of the BER pathway may be associated with cancer risk in BRCA1/2 mutation carriers and should be more comprehensively studied.},

  abstract  = {p53 protects us from cancer by transcriptionally regulating tumor suppressive programs designed to either prevent the development or clonal expansion of malignant cells. How p53 selects target genes in the genome in a context-and tissue-specific manner remains largely obscure. There is growing evidence that the ability of p53 to bind DNA in a cooperative manner prominently influences target gene selection with activation of the apoptosis program being completely dependent on DNA binding cooperativity. Here, we used ChIP-seq to comprehensively profile the cistrome of p53 mutants with reduced or increased cooperativity. The analysis highlighted a particular relevance of cooperativity for extending the p53 cistrome to non-canonical binding sequences characterized by deletions, spacer insertions and base mismatches. Furthermore, it revealed a striking functional separation of the cistrome on the basis of cooperativity; with low cooperativity genes being significantly enriched for cell cycle and high cooperativity genes for apoptotic functions. Importantly, expression of high but not low cooperativity genes was correlated with superior survival in breast cancer patients. Interestingly, in contrast to most p53-activated genes, p53-repressed genes did not commonly contain p53 binding elements. Nevertheless, both the degree of gene activation and repression were cooperativity-dependent, suggesting that p53-mediated gene repression is largely indirect and mediated by cooperativity-dependently transactivated gene products such as CDKN1A, E2F7 and non-coding RNAs. Since both activation of apoptosis genes with non-canonical response elements and repression of pro-survival genes are crucial for p53's apoptotic activity, the cistrome analysis comprehensively explains why p53-induced apoptosis, but not cell cycle arrest, strongly depends on the intermolecular cooperation of p53 molecules as a possible safeguard mechanism protecting from accidental cell killing.},

  abstract  = {DNA double strand break (DSB) formation induced by ionizing radiation exposure is indicated by the DSB biomarkers \(\gamma\)-H2AX and 53BP1. Knowledge about DSB foci formation in-vitro after internal irradiation of whole blood samples with radionuclides in solution will help us to gain detailed insights about dose-response relationships in patients after molecular radiotherapy (MRT). Therefore, we studied the induction of radiation-induced co-localizing \(\gamma\)-H2AX and 53BP1 foci as surrogate markers for DSBs in-vitro, and correlated the obtained foci per cell values with the in-vitro absorbed doses to the blood for the two most frequently used radionuclides in MRT (I-131 and Lu-177). This approach led to an in-vitro calibration curve. Overall, 55 blood samples of three healthy volunteers were analyzed. For each experiment several vials containing a mixture of whole blood and radioactive solutions with different concentrations of isotonic NaCl-diluted radionuclides with known activities were prepared. Leukocytes were recovered by density centrifugation after incubation and constant blending for 1 h at 37°C. After ethanol fixation they were subjected to two-color immunofluorescence staining and the average frequencies of the co-localizing \(\gamma\)-H2AX and 53BP1 foci/nucleus were determined using a fluorescence microscope equipped with a red/green double band pass filter. The exact activity was determined in parallel in each blood sample by calibrated germanium detector measurements. The absorbed dose rates to the blood per nuclear disintegrations occurring in 1 ml of blood were calculated for both isotopes by a Monte Carlo simulation. The measured blood doses in our samples ranged from 6 to 95 mGy. A linear relationship was found between the number of DSB-marking foci/nucleus and the absorbed dose to the blood for both radionuclides studied. There were only minor nuclide-specific intra-and inter-subject deviations.},
