The inhibitory effects of 250 KVP x-radiation on the electroretinographic response (ERG) of the rabbit were investigated. Rabbits were exposed (head only) to either a single dose ranging from 3,000 rad to 8,000 rad or to a fractionated dose, two doses of 3,000 rod each with an interval of 5 days. ERG responses of the dark adapted eyes of the rabbit were determined prior to exposure and at vario...

The mRNA expression of two activin growth factor subunits ( Aand C-activin), activin receptor subunits (ActRIIA, ActRIIB) and the activin-binding protein follistatin, and peptide expression of A-activin and C-activin subunits, were examined in regenerating rat liver after partial hepatectomy (PHx). Liver samples were collected from adult, male Sprague–Dawley rats, 12–240 h (n=3–5 rats per time ...

Alix is a cytosolic protein in mammalian cells that was originally identified on the basis of its association with pro-apoptotic signaling. More recent evidence has established that Alix has a hand in regulating other cellular mechanisms, including endocytic membrane trafficking and cell adhesion. Although Alix appears to participate directly in these various activities, the role it plays in ea...

The work presented here aims at understanding the nature, epigenesis and function of personality types (here called behavioral profiles) in birds, focusing on a wild bird species, the great tit (Parus major). Lines bidirectionally selected for exploration show a wide array of social and non-social behavioral differences, and also some differences in physiological parameters. Line differences in...

Sir William Osler (Figure 1) arrived in Britain in 1905 determined not only to guide Oxford medicine as its Regius Professor but also to improve the standard of postgraduate medicine throughout Britain. He felt that each county hospital should have a postgraduate department, using the argument that without postgraduate education a doctor was stale in five years, in the rut by ten years, and by ...

Controversy surrounds the contention that certain psychological factors correlate highly with cancer and coronary heart disease (CHD). This study provides further empirical evidence on this issue. Special consideration is given to GrossarthMaticek’s theory of personality types, according to which Type 1 personalities are more susceptible to cancer and Type 2 personalities to CHD. h total of 185...

Dynamic linear modeling (DLM) analysis was performed to identify the long-term temporal trends of two toxic components of the technical chlordane pesticide, aand g-chlordane, in skinless–boneless muscle tissues of a number of sport fish species in Lake Erie. Our analysis considers the fish length as a covariate of the chlordane concentrations. The a-chlordane models for the coho salmon, channel...
