Professionalizing Healthcare Management: A Descriptive Case Study

Despite international recognition of the importance of healthcare management in the development of high-performing systems, the path by which countries may develop and sustain a professional healthcare management workforce has not been articulated. Accordingly, we sought to identify a set of common themes in the establishment of a professional workforce of healthcare managers in low- and middle...

Food and Its Relation to Public Health *

The human embryo is provided with the predigested food of the mother by means of the fetal circulation. After birth provision has been made for another highly nutritious and readily available source of food to the infant through the mammary gland of the mother. Normal infants under the usual conditions survive this period fairly well. Most of the trouble from food comes after the infant has bee...

Origin of Myeloschisis in Chick Embryos Infected with Influenza-A Virus ‡

Nucleic Acid and Protein Changes During Embryonic Organ Development in the Chick †

The rapid acceleration of an embryo into an increasingly heterogeneous organism begins early in development with a flood of biochemical changes that accompanies the appearance and growth of organs. The nucleic acids, particularly the ribonucleic acids (RNA), are involved in these profuse changes although the manner of their involvement is only partly understood. We are attempting to define furt...
