Carney, S. A., Lawrence, J. C., and Ricketts, C. R. (1970). Brit. J. industr. Med., 27, 72-76. Effect of microwaves at X-band on guinea-pig skin in tissue culture. 3. Effect of pulsed microwaves on skin respiration and biochemistry. Small pieces of guinea-pig skin were exposed to known power densities of pulsed microwaves at X-band (9-6 GHz). The pulse duration was 0 25 microsecond and the puls...

The central role that phosphates play in biological systems, suggests they also played an important role in the emergence of life on Earth. In recent years, numerous important advances have been made towards understanding the influence that phosphates may have had on prebiotic chemistry, and here, we highlight two important aspects of prebiotic phosphate chemistry. Firstly, we discuss prebiotic...

Problems of lignin formation have long occupied the attention of investigators, however, neither the physiological nor chemical mechanisms involved in lignification is known in detail. Nevertheless, a considerable body of knowledge has accumulated through the investigations of Freudenberg, Nord, Brown, Wardrop, and others (4, 5, 6, 10, 13, 15, 23), especially on the biochemistry, histochemistry...

Chalcogen-nitrogen chemistry deals with systems in which sulfur, selenium, or tellurium is linked to a nitrogen nucleus. This chemical motif key component of different functional structures, ranging from inorganic materials and polymers, rationally designed catalysts, bioinspired molecules enzymes. The formation selenium–nitrogen bond, typically occurring upon condensation an amine the unstable...

Alkaline phosphatase (AP) enzymes are of broad interest in fields ranging from biochemistry and medicine to biotechnology nanotechnology. Characterising the catalytic activity AP is typically realised by either employing non-natural signal-generating substrates that detectable absorbance fluorescence spectroscopy or quantifying release inorganic phosphate classic malachite green assay. The latt...
