BACKGROUND If brief and easy to use self report screening tools are available to identify frail elderly, this may avoid costs and unnecessary assessment of healthy people. This study investigates the predictive validity of three self-report instruments for identifying community-dwelling frail elderly. METHODS This is a prospective study with 1-year follow-up among community-dwelling elderly a...

In the second half of the 19th century, medical researchers paid increasing attention to the so-called ductless (endocrine) glands. In 1848, German physiologist Arnold Berthold provided the first evidence that one of these glands could secrete a physiologically active substance directly into the bloodstream. A castrated rooster normally exhibited a shrinking of its comb, but Berthold showed tha...

Previous research has shown that the sperm quality index (SQI) of rooster semen is indicative of overall semen quality. The objectives of the present experiments were to determine the correlation of the SQI with semen characteristics and fertility and to determine if selection of young males for the SQI would improve fertility. In Experiment 1 semen was collected from 35 Peterson males and was ...
