The determination of pyridoxal phosphate by the measurement of ¹⁴Co₂ enzymatically released from tyrosine-1-¹⁴C

Creator:: Woodring, Muriel Josepha
Abstract:: The increasing knowledge of the significance of vitamin B₆ in human metabolic processes has emphasized the importance of developing reliable means of assessing nutritional status with respect to this vitamin. One possible approach to this end is the measurement of pyridoxal phosphate in blood or plasma, particularly since this phosphorylated...

The site of action of radio-lethal compounds on Micrococcus radiodurans

Creator:: Manes, Jasper Damon, Jr.
Abstract:: Iodoacetic acid and diphenylamine were used in this study to elucidate the mechanisms of resistance of Micrococcus radiodurans to radiation. This organism, a gram positive, non-spore forming, salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in the absence of radio-modifying agents. M. radiodurans, when grown in media containing...

The effect of dimethyl sulfoxide (DMSO) on the radiosensitivity of the rough-skinned newt (Taricha granulosa)

Creator:: Lappenbusch, William L.
Abstract:: More than 2,000 male newts were collected during the summer and maintained unfed at 10°C both pre- and post-irradiation. Exposures ranging up to 30 kR were given with 300 kVp X-rays and ⁶⁰Co gamma rays. Half of the newts were injected (I. P.) with 15 g DMSO/kg (the maximum sublethal...

The uptake, retention, and distribution of ⁶⁰Co, ⁶⁵Zn, ⁸⁵Sr, and ¹³¹I in the rough-skinned newt (Taricha Granulosa) : A radio-ecological study

Creator:: Valett, Bryan Batson
Abstract:: The uptake, retention, and distribution of ⁶⁰Co, ⁶⁵Zn, ⁸⁵ Sr, and ¹³¹I was examined in the Rough-Skinned Newt (Taricha granulosa). Each of these radionuclides is a possible contaminant of the freshwater environment and, thus, is of importance in radioecology. The newts were maintained singly at 10° C in an unfed...

Radiotracer methodology in biological science

Creator:: Willis, David L.
Abstract:: The use of radioactive isotopes as tracers in biological systems has become widespread since the close of World War II. Proper use of radiotracers requires a fundamental understanding of the physical nature of radioactivity, the characteristics of ionizing radiation, and the various methods available for measuring radioactivity. More importantly, the...

Osmotic and ionic regulation in the North American crayfish Pacifastacus leniusculus (dana)

Creator:: Kerley, David Emmet
Abstract:: Osmotic and ionic regulation was studied in the North American crayfish Pacifastacus leniusculus (Dana), stepwise acclimated to increasing salinities. Stepwise acclimation involved transferring crayfish at 48 hour intervals from freshwater to 100% seawater in 20% increments. In experiments where 70% seawater was used, animals were moved directly from 40 to...
