    Notes: Abstract Social support research has been hampered by a lack of clarity both in the definitions of social support and in the conceptualization of its effects on health outcomes. The present study compared social network size and three types of perceived social support—tangible, emotional, and informational —in relation to stressful life events, psychological symptoms and morale, and physical health status in a sample of 100 persons 45–64 years old. Social network size was empirically separable from, though correlated with, perceived social support and had a weaker overall relationship to outcomes than did support. Low tangible support and emotional support, in addition to certain life events, were independently related to depression and negative morale; informational support was associated with positive morale. Neither social support nor stressful life events were associated with physical health. It was concluded that social support research would benefit from attention to the multidimensionality of support and greater specificity in hypotheses about the relationship between types of support and adaptational outcomes.

    Notes: Abstract The standard life events methodology for the prediction of psychological symptoms was compared with one focusing on relatively minor events, namely, the hassles and uplifts of everyday life. Hassles and Uplifts Scales were constructed and administered once a month for 10 consecutive months to a community sample of middle-aged adults. It was found that the Hassles Scale was a better predictor of concurrent and subsequent psychological symptoms than were the life events scores, and that the scale shared most of the variance in symptoms accounted for by life events. When the effects of life events scores were removed, hassles and symptoms remained significantly correlated. Uplifts were positively related to symptoms for women but not for men. Hassles and uplifts were also shown to be related, although only modestly so, to positive and negative affect, thus providing discriminate validation for hassles and uplifts in comparison to measures of emotion. It was concluded that the assessment of daily hassles and uplifts may be a better approach to the prediction of adaptational outcomes than the usual life events approach.

    Notes: The 13C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12,14-orthoacetate-3, 16-diacetate.

    Notes: Using the carbon assignments of bleomycin A2 as well as those of a series of model compounds, the 13C NMR assignments of the antitumor antibiotic tallysomycin (TLM) have been made. With the aid of the carbon assignments the metal binding properties of the new antibiotic toward Zn(II) have been investigated.

    Notes: Raman spectra have been obtained for bleomycin A2 and selected fragments. Virtually all of the features in the bleomycin Raman spectrum can be attributed to the preresonance enhanced vibrational transitions of the 2,4′-bithiazole moiety as determined by comparison to the Raman spectra of bithiazole fragments. The Raman spectrum of bleomycin is dominated by a very intense band at 1542 cm-1 that can be approximately assigned as a bithiazole ring stretching mode. This feature may serve as a probe of bithiazole environment in bleomysin -DNA interactions.
