    Sexuality and aging in male veterans: A cross-sectional study of interest, ability, and activity (1991)

    Notizen: Abstract To gather data on sexuality, specifically in male veterans, and to test the hypothesis that aged males remain interested in sexual intercourse yet suffer from erectile failure, veterans age 30 to 99 were surveyed. The mailed survey had 88 questions and was pretested on young potent males and aged impotent males. From 1031 randomly selected subjects, there were 806 replies: 427 completed surveys, 247 refusals, and 132 who were too ill to participate (225 failed to reply). Among responders, sexual interest declined from a mean of 4.4/5 (4 = very interested, 5 = extremely interested) in men age 30–39 years to 2.0/5 (2 = slightly interested) in men age 90–99 (p 〈 0.0001). Vaginal intercourse was consistently the preferred sexual activity; however, intercourse frequency was diminished from a mean of once per week in 30- to 39-year-olds to once per year in 90- to 99-year-olds (p 〈 0.0001). Frequency, rigidity, and duration of erections were less in aged compared to younger cohorts (p 〈 0.0001). With these facts in mind, further research to bridge the libido-potency gap is warranted.

    Combined gas chromatography-infra-red spectroscopy for the determination of propanediol in acyclovir cream (1996)
    Springer
    Chromatographia 42 (1996), S. 305-308 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Gas chromatography-IR spectroscopy ; Propanediol ; Acyclovir

    Thema: Chemie und Pharmazie
    Notizen: Summary A simple procedure is described for the determination of the 1,2-propanediol (propylene glycol) content of cream formulations containing the antiviral drug Acyclovir. Analysis of a solvent extract by gas chromatography coupled to an infra-red spectrometer enables the target analyte to be positively identified and an estimate of its concentration to be made. This application utilises the newer Tracer cryogenic deposition interface for gas chromatography and infra-red spectroscopy. This offers an alternative and complementary analytical strategy to gas chromatography coupled to mass spectrometry.
