Vitellogenin, the precursor of egg yolk phosphoproteins, is synthesized in the liver of the laying hen but is not normally synthesized by roosters. Administration of 17/?estradiol to roosters induces the synthesis of large amounts of this protein and its messenger RNA. We have purified vitellogenin messenger RNA from the livers of estrogentreated roosters and have characterized it as follows: (...

Eight chlamydial isolates of ovine origin were tested in a plaque reduction system using homologous and heterologous rooster antisera. The eight isolates could be separated into two separate immunotypes. Type 1 included isolates associated with ovine abortion and one agent recovered from the feces of an apparently normal sheep. Type 2 isolates were associated with polyarthritis and conjunctivit...

Using data from the 1982-84 National Long-Term Care Channeling Demonstration, this study examines factors associated with long-term care service use by African American, Hispanic, and white frail elders living in the community. Findings indicate that in addition to predisposing, enabling, and need factors, race/ethnicity is a significant predictor of each type of service use.

In this paper we briefly describe the results of a 3 year project examining the use of Health Information Technologies (e.g., electronic patient record systems) to deliver integrated care. In particular, we focus on one group of patient (the frail elderly) and efforts to design an e-health supported healthcare pathway (the frail elderly pathway--FEP). The aim of FEP is to bring together clinici...

Health professionals and government policy-makers have realized the important contribution that family members make in caring for the frail elderly in the community. How can we best support them in this important role? One method of offering assistance to family caregivers is through groups to provide education and mutual support. Interestingly, evaluations of the benefits of these groups, usin...

BACKGROUND The number of elderly people persons suffering from dizziness is substantial, and dizziness is a risk factor for falls and fractures. Fall-related fractures represent a major public health issue. Longitudinal studies can help find ways of predicting fall-related fractures among frail elderly persons with multisensory dizziness. The aim of the present study was therefore to investigat...
