    Notes: Summary Bilateral lesions were induced in the entopeduncular nuclei of eight treadmill-trained cats. The pre- and postoperative locomotor performances of these cats were then compared, with no notable differences being apparent. This finding is discussed in relation to phylogenetic differences in the neural control of locomotor behavior.

    Description / Table of Contents: Summary In the Berlin Aging Study (BASE) an age and gender stratified sample of 516 persons aged 70 to over 100 was assessed by means of the semi-structured GMS-A interview, the CES-D-self-rating scale and the Hamiltion-Depression-observer-rating scale. Prevalence rates were 4,8% for Major Depression, 9,1% for all DSM III-R specified depressive disorders and 26,9% of subthreshold depression was included. There was no increase in prevalence rates with age but an increase in scores on the self rating CES-D. The prevalence rates for DSM III-R specified depression in females was 10,3% and almost double that of men (5,6%). Depressed persons do not show significant cognitive impairment as measured with the MMSE in comparison to controls. As compared to the total sample higher prevalence rates of overall depression were seen in persons with multimorbidity (36,8%) and lower rates in married persons. 13,2% of the elderly talked about feeling tired with life, 7,9% had thoughts about death and 1,2% reported suicidal ideation, which was closely linked to depressive disorders. In 44% of depressed cases undertreatment was observed. Only 6% got Antidepressants but 40% benzodiazepines.
    Notes: Zusammenfassung In der Berliner Altersstudie (BASE) wurde eine nach Alter und Geschlecht geschichtete Stichprobe von 516 Studienteilnehmern im Alter von 70 bis über 100 Jahren untersucht. Zur Diagnostik von depressiven Erkrankungen wurde neben den Fremd- und Selbstratingskalen (HAMD und CES-D) das halbstrukturierte GMS-A-Interview eingesetzt, auf dessen Basis Diagnosen nach DSM III-R erstellt wurden. Es fand sich eine Prävalenz von 9,1% für alle nach DSM III-R spezifizierten depressiven Störungen, wovon 4,8% Major Depression waren. Bei Hinzunahme von nach klinischer Einschätzung krankheitswertigen Depressionen, welche die Kriterien für eine spezifizierte DSM III-R-Diagnose jedoch nicht erfüllten, steigt die Depressionsprävalenz auf 26,9% an. Die Häufigkeiten in den verschiedenen Altersgruppen unterscheiden sich mit Ausnahme bei der CES-D nicht signifikant. Die Depressionsprävalenz für spezifizierte DSM III-R-Diagnosen ist bei Frauen mit 10,3% etwa doppelt so hoch wie bei Männern (5,6%). Depressive Patienten zeigen im Vergleich zu Kontrollpersonen keine signifikant schlechteren Werte im MMSE. Eine signifikant erhöhte Depressionsprävalenz findet sich im Vergleich zur Gesamtstichprobe bei Personen mit Multimorbidität (36,8%). Verheiratete Studienteilnehmer zeigen seltener eine depressive Erkrankung (14,9%). 13,2% der alten Menschen sprechen von Lebensüberdruß, 7,9% äußern einen Todeswunsch und 1,2% Suizidgedanken. Es besteht eine enge Beziehung zwischen Suizidalität und depressiven Erkrankungen. Im Bezug auf die Behandlung depressiver Störungen fand sich in 44% eine unzureichende Therapie. 6% der depressiven Studienteilnehmer wurden mit Antidepressiva behandelt, während 40% nur Benzodiazepine bekamen.

    Description / Table of Contents: Summary We investigated time use of persons assigned to seven groups on the basis of psychiatric diagnoses: (a) no dementia or depression symptoms, (b) individuals with dementia symptoms but no DSM-III-R-diagnosis, (c) individuals with dementia according to DSM-III-R, (d) individuals with depression symptoms but no diagnosis, (e) individuals with depression not further specified (NFS), (f) individuals with depression according to DSM-III-R, and (g) individuals with symptoms of both dementia and depression. In general, time-use parameters were similar across the groups. As expected, however, we found differences in specific dimensions. Demented and depressed individuals differed from others with respect to the duration of pas- sive phases and receptive leisure. Instrumental activities, active leisure, length of the waking day, and time spent alone were indicators with differential validity regarding dementia diagnoses – partly even after controlling for physical morbidity. Moreover, we were able to differentiate between dementia and depression on the basis of instrumental activities after controlling for physical morbidity.
    Notes: Zusammenfassung Wir haben die Zeitverwendung von Personen in 7 aus der psychiatrischen Diagnostik resultierenden Gruppen verglichen: a) Probanden ohne dementielle oder depressive Symptome, b) Probanden mit einzelnen Demenz-Symptomen ohne Krankheitswert, c) Probanden mit Demenz nach DSM-III-R, d) Probanden mit depressiven Symptomen ohne Krankheitswert, e) Probanden mit Depression NNB, f) Probanden mit Depression nach DSM-III-R und g) Probanden, bei denen es (mindestens) Symptome beider Erkrankungen gab. Generell erwies sich die Gestaltung des Tages in den Gruppen als ähnlich. Wie erwartet konnten jedoch in spezifischen Dimensionen Unterschiede ausgemacht werden. Demente und depressive Probanden unterschieden sich hinsichtlich der Dauer von Ruhezeiten und der „rezeptiven Freizeit” gleichsinnig von den übrigen Personen. Instrumentelle Aktivitäten, aktive Freizeit, Ta- geslänge und allein verbrachte Zeit besaßen differentielle Validität hinsichtlich Demenz-Diagnosen, z.T. auch nach Berücksichtigung körperlicher Morbidität. Die Berücksichtigung körperlicher Morbidität ermöglichte auch, auf der Basis der instrumentellen Aktivitäten Demenz- und Depressions-Diagnosen voneinander zu differenzieren.

    Notes: Abstract Supported vanadium oxide catalysts are prepared by adsorption and subsequent calcination of the vanadyl acetylacetonate complex on silica by liquid phase and gas phase modification. The influence of the pretreatment temperature and the effect of the solvent in the liquid phase are discussed. Two types of gas phase deposition processes are used: flow-type reactions and vacuum deposition. The bonding mechanism, the influence of pretreatment temperature of the support and the influence of the reaction temperature are investigated by FTIR, XRD, TGA and chemical analysis. After calcination the obtained vanadium oxide layer is characterized by XRD and UV-Vis diffuse reflectance spectroscopy. The gas phase modification enables the creation of well dispersed supported VOx catalysts. Loadings up to 1.4 mmol g-1 (7 wt% V) without the formation of a crystalline fraction can be achieved. The selective oxidation of methanol to formaldehyde is used as a probe reaction to assess the catalytic activity and selectivity of the catalysts. It is shown that not the concentration of vanadium species, but their surface configuration is the determining factor in catalytic reactions.
