This is the fourth of a series of yearly conferences on the physiology of prematurity, which are attended by 25 invited persons of varied disciplines. These bring their different approaches to bear in the discussions which center about an informally presented topic on a given day in which one or two of the guests are featured. This conference was built around three topics: heat regulation (pres...

‘The study of nutrition and the study of enzymes represent two sides of the same coin’ (Green, 1946). This statement is specially applicable in cases of nutritional oedema and kwashiorkor, both being states of protein malnutrition. Since enzymes are protein in nature it is to be expected that protein malnutrition will lead to a diminution in the quantity of enzymes. Acute starvation in rats pro...

An analysis of the type presented is highly unusual, but most timely in view of the rapid changes occurring in this and other branches of applied biology. Mammary physiology is here interpreted broadly to include cognate sciences, fundamental and applied aspects, and both medical and dairying contexts, though references to the latter predominate. To aid discussion, ‘validity’ is considered unde...

I t has been claimed by a number of workers that handling rats during the early part of their lives makes them grow faster (Weininger, 1954, 1956; Weininger, McClelland & Arima 1954; Ruegamer, Bernstein & Benjamin, 1954; Ruegamer & Silverman, 1956; McClelland, 1956; Levine, 1957; Mogenson, McMurray & Jaques, 1957; Levine & Otis, 1958), though others have not invariably obtained this result (Sco...

We have seen personally more than IOO cases of rickets and osteomalacia in Asian immigrant patients during the past 6-8 years and we are satisfied that they arise simply on a basis of vitamin D deficiency. The present report is concerned principally with a more detailed study of thirtysne patients, aged 11-54 years. Our patients have been adult women, often pregnant at the time of diagnosis, an...

Introduction In 1963 Dr L. J. Harris, the first secretary of the Nutrition Society, wrote a brief history of the Society on the occasion of the 6th International Congress of Nutrition held in Edinburgh. He declared his intention of filling in the facts of the intriguing early history of the Society and also of its later affairs. However, he did not find time to do this and it is the loss of the...

In the comparatively short history of Antarctic exploration the scourges of scurvy and semi-starvation have played as important a part in the success or failure of expeditions as have the hazards of exposure and accident. Studies have recently been made of the mechanisms that might be involved in man's physiological response to polar conditions (Lewis & Masterton, 1963). These have included rou...

Humans intensely use southern California rocky shores for recreational activities such as fishing, exploration, wallung, enjoyment of the out-of-doors, and educational field trips. People also collect intertidal organisms for consumption, fish bait, home aquariums, and other purposes. In Orange County, visitors concentrate their activities on a few rocky headlands and reefs. Many of these shore...
