have rendered a fine service in presenting us with such a carefully prepared resume of Starling's work and their devoted work will receive wide acclamation. The reviewer's only criticism is the lack of more biographical information on the main characters in this drama of experimental investigation. Sidney Patterson for example was working as a general practitioner in a small wheat town in Austr...

Diaminopimelic acid, which is widely distributed in bacteria, is converted into lysine by a specific decarboxylase (Work & Dewey, 1953; Dewey, Hoare & Work, 1954; Antia, Hoare & Work, 1957), and it has been suggested as an immediate precursor of lysine in some bacteria. A mutant of Escherichia coli deficient in the decarboxylase requires lysine for growth and accumulates diaminopimelic acid in ...

need financial support because both his mother and father had died when he was an undergraduate leaving him financially independent. As a Quaker and conscientious objector he was exempted from military service and could begin research immediately, even though the country was at war. He studied the metabolism of lysine under the direction of Albert Neuberger. Fred had a very high regard for Neub...

The Strangeways Research Laboratory, Cambridge, an independent research institution of world-wide renown, was founded as the Cambridge Research Hospital in 1905. The Contemporary Medical Archives Centre at the Wellcome Institute holds the important archive of the Strangeways itself (which includes papers of its founder, Thomas Strangeways Pigg Strangeways, 1866-1926), and also the papers of the...

We report on an interferometry-based measurement of the phase and group velocities of optical Bessel beams, providing confirmation of their superluminal character in the non-diffractive region. The measurements were performed in free space with a continuous wave laser and femtosecond pulses for phase and group velocities respectively. The Bessel beams were produced using a conical mirror. Einst...

Background In these days when it is extremely important to use resources efficiently, ways reduce the cost caused by low back and neck pain are sought. Investigating architectural features of muscles around spine also an part this search [1]. It a rational approach prevent spinal problems before they occur, rather than treat them. addition, very for prevention health that approaches can be offe...

FOR some years we have been engaged on the problem of extracting enzymes from micro-organisms. It is well known that most bacteria and yeasts carry out oxidations and metabolic processes at a rate incomparably higher than that of animal tissues. The peculiar virtue of micro-organisms as the source of enzymes is therefore self-evident. A certain amount of success has been attained in extracting ...

WHILE the rat has been used in recent years with great success in nutritional studies, the results obtained have proved to be misleading in the investigation of pellagra. Goldberger and his co-workers discovered that rats ceased to thrive, became ill and developed a symmetrical dermatitis when deprived of the heatstable portion of the B vitamin complex contained in yeast and concluded that this...
