λ5-Phosphorus-Containing α-Diazo Compounds: A Valuable Tool for Accessing Phosphorus-Functionalized Molecules

Phosphorus compounds in animal tissues; the distribution of nucleic acids and other phosphorus-containing compounds in normal and malignant tissues.

Malignant tissues are distinguished from other types of tissues by their capacity for relatively unlimited and uncontrolled growth in the organism. The reason why neoplastic tissues grow continually, in contrast to embryonic tissues which grow only up to a certain point before they begin to differentiate, is a fundamental problem of cancer research. A study of the synthetic mechanisms of the ce...

Biocompatible Phosphorus Containing Photopolymers

Radical photopolymerization is the key technique to prepare films and coatings in an environmentally friendly way within the fraction of a second. During the last decade this technique has found access to many other categories, as for example rapid prototyping, manufacturing of printed circuits boards, dental filling materials and other biomedical applications. Photopolymers display several adv...

Catalytic decomposition of phosphorus compounds to produce phosphorus atoms

Phosphorus Compounds in Animal Tissues

The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...

Phosphorus Compounds in the Cell

In the first paper in this series (Davidson, Frazer & Hutchison, 1951) it was emphasized that in experiments on the incorporation of radioactive phosphorus (32p) into the nucleic acids and their derivatives in the cell, it was essential, in order to obtain true specific activities, to separate the nucleotide fractions in a form free from all traces of highly active contaminants. The procedure o...
