The proposal that diastolic coronary flow is regulated by an intramyocardial "back-pressure" that substantially exceeds coronary venous and ventricular diastolic pressures has been examined in an open-chest canine preparation in which instantaneous left circumflex pressure and flow could be followed to cessation of inflow during prolonged diastoles. Despite(More)
The molecular structure of EPO has been discussed, and the gradual emergence of information about EPO has been reviewed. The importance of certain regions of the molecule and of glycosylation to EPO's structure and function are clear. Although its nucleotide and amino acid sequences are known, its tertiary structure remains elusive. Antipeptide antibody and(More)
The binding of erythropoietin (Epo) to its plasma membrane receptor activates signal pathways that result in erythroid cell proliferation and differentiation. To elucidate the structural features of the receptor that are important for hormone binding and signaling, we have developed a series of site-specific antibody probes. These antibodies were raised(More)

The authors propose that the process of psychic change involves the 'working through' of mourning for the loss of 'theories of life' that are based on narcissistic omnipotent beliefs. These theories need to be changed by other more realistic ones regarding how to resolve the inherent and natural problems of existence. Questioning the 'truth' of these(More)
