Studies on trehalose phosphate synthetase in Mycobacterium smegmatis
The biosynthesis of trehalose phosphate occurs by two reactions which utilize different sugar nucleotides, UDP-glucose or GDP-glucose. Cell free extracts of several mycobacteria catalyzed the synthesis of trehalose phosphate ...
Some effects of light intensity and oxygen concentration of Chlorella sorokiniana and an oxygen resistant strain
Experiments were carried out to compare the thermotolerant unicellular green alga Chlorella sorokiniana and an oxygen resistant strain isolated from the species. Studies were made at 39°C over a range of light intensities ...
Hormonal and radiation effects on osteoclastic proliferation
The past century of research on bone physiology has established that the osteoclast is involved in the resorption of bone. The presence of parathyroid hormone in the circulating body fluids causes the calcium concentration ...
Some aspects of sulfur metabolism in the lugworm, Arenicola cristata Stimpson
Among the published reports on invertebrate biochemistry is a study by Robin (1954) using Arenicola marina L. Robin hypothesized that taurocyamine, a sulfur-containing guanidine derivative, was formed from taurine. Although ...
A cytological study of the hypodermis of the parasitic nematode, Capillaria hepatica
Both electron microscopy and light microscope histochemistry have been used to describe the cytology of the hypodermis of the parasitic nematode, Capillaria hepatica. The hypodermis of the mid portion of the body of this ...
Quantitative relationship of osteoclasts to parathyroid function
Over the last decade the tempo of research on the parathyroid gland and its relationship to metabolism has increased rapidly. As new advances in our knowledge of calcium and phosphorus metabolism are made, old ideas and ...
Mammalian amino acid decarboxylases
Abstract Not Available.
Studies on the absorption of methionine by the rat cestode, Hymenolepis diminuta
The number of species of tapeworms readily available for laboratory control is quite limited. Two species in particular seem best suited for testing the interesting hypothesis propounded by Read, Simmons, Campbell and ...
