    Notes: Zusammenfassung 1. Es wird eine maßanalytische Methode zur Bestimmung des Berylliums in Anwesenheit von Fluor beschrieben. Die Methode besteht darin, daß Berylliumsalzlösungen, die keine freie Säure enthalten, mit einer eingestellten Alkalilösung (frei von CO2) titriert werden, nachdem man vorher einen überschuß von neutralisierter CaCl2-Lösung zwecks Zerstörung des Komplexes Na2(BeF4) zugegeben hat. Das Titrieren wird mit Phenolphthalein als Indikator ausgeführt in einer Lösung, die zum Schluß beinahe bis zum Sieden erhitzt wird. 2. Unbedeutende Beimengungen von Aluminium- und Eisensalzen haben wenig Einwirkung auf die Ergebnisse der Titration. 3. Der Vorzug der Methode besteht in ihrer Schnelligkeit. Das ist besonders wichtig deswegen, weil die Bestimmung des Berylliums auf gewichtsanalytischem Weg mit einem zeitraubenden Eindampfen mit konzentrierter Schwefelsäure, zwecks Entfernung des Fluors, verbunden ist. 4. Die Methode kann zur Produktionskontrolle empfohlen werden.

    Mapping of obesity QTLs in a cross between mouse lines divergently selected on fat content (2000)

    Notes: Abstract. A genome-wide quantitative trait locus (QTL) analysis was performed in a polygenic obesity mouse model resulting from a long-term selection experiment. The parental lines were outbred lines divergently selected for 53 generations for high-fat (fat, F line) or low-fat (lean, L line) percentage (fat%) that differed fivefold in fat% at 14 weeks of age. An F2 population of 436 mice was used for the QTL analysis with 71 markers distributed across the genome. The analysis revealed significant QTLs Fob1 (for F-line obesity QTL 1), Fob2, Fob3, and Fob4, on Chromosomes (Chrs) 2, 12, 15, and X, respectively. None of these QTLs map to regions of known single gene obesity mutations (Lep ob , Lepr db , Cpe fat , A y , tub), though they map to regions of previously described obesity QTLs and candidate genes. The effects of Fob1, Fob3, Fob4 were additive, and that of Fob2 was dominant. Fob2 also showed a significant female-specific effect. Fob1, Fob2, Fob3, and Fob4 explained 4.9%, 19.5%, 14.4%, and 7.3% of the F2 phenotypic variance for fat%, respectively. This study identified four loci that contributed to the response to divergent selection and control a significant proportion of the difference in obesity between the F and L lines.

    A novel method for investigating the uptake and distribution of radiolabelled imazethapyr in potato tubers (2000)

    Notes: Summary The use of imazethapyr as a sprout suppressant in potatoes has been investigated. Novel radionuclide techniques were developed to establish the patterns of uptake and movement of imazethapyr in potatoes. Protocols for tissue analysis were established to homogenise potato tuber tissue samples, enabling radiolabel recovery by liquid scintillation counting to approach 100%. The movement of imazethapyr was also examined in the presence of an acidic formulation of thiabendazole which caused increased uptake. The movement of imazethapyr within the tuber was also influenced by pH and ion trapping.

    Development of a Cervical Cancer Control Intervention Program for Cambodian American Women (2000)

    Notes: Abstract Southeast Asian immigrants have lower levels of Pap testing than any other racial/ethnic group in the US, and are particularly unfamiliar with western culture and biomedical concepts of prevention. We completed an ethnographic study (N = 42) focusing on cervical cancer screening among Cambodian American women. We also conducted a community-based survey (N = 413) to examine the generalizability of our qualitative results. This report summarizes the results, and describes how we used our findings to influence the content of a multifaceted intervention program targeting Cambodian immigrants. The following constructs were found to be barriers to cervical cancer control: a traditional orientation to the prevention, causation, and treatment of disease; lack of familiarity with western early detection concepts; low levels of knowledge about cervical cancer; concerns about the Pap testing procedure; and health care access issues. In general, the quantitative results confirmed our ethnographic findings. The intervention program, which is delivered by bicultural outreach workers, includes home visits, presentations at small group meetings, barrier-specific counseling, use of a Khmer-language video, and tailored logistic assistance (e.g., transportation and medical interpretation). Both the video and presentation provide cultural context while simultaneously addressing multiple barriers to screening (e.g., women's fear of surgery and preference for female providers). Outreach workers are trained to counsel women about 10 potential barriers including avoidance of biomedicine, perceptions that gynecologic exams are embarrassing, and lack of English proficiency. Our results reinforce the importance of considering health problems within the context of a population's traditional belief systems and daily routines.

    Serum Cholesterol Concentrations and Mood States in Violent Psychiatric Patients: An Experience Sampling Study (2000)

    Notes: Abstract The well-documented negative association between serum cholesterol and aggressive behavior has led Kaplan to propose a cholesterol–serotonin hypothesis of aggression. According to this hypothesis, low dietary cholesterol intake leads to depressed central serotonergic activity, which itself has been reported in numerous studies of violent individuals. In the present study, 25 violent psychiatric patients participated in a microbehavioral experience sampling procedure to examine differences in self-reports of affective and cognitive experiences as a function of serum cholesterol concentrations. For 7 days, they wore signaling devices that emitted an average of seven signals a day. Following each signal, patients filled out a mood questionnaire. Total serum cholesterol (TSC) concentration was positively associated with measures of affect, cognitive efficiency, activation, and sociability, suggesting a link between low TSC and dysphoria. These findings are consistent with the cholesterol–serotonin hypothesis and with the substantive literature linking both aggression and depression to depressed central serotonergic activity.
