Antibiotics and evolution: food for thought
The role of secondary metabolites in effecting and modulating reactions during early biochemical evolution has been largely unappreciated. It is possible that low molecular weight effectors were gradually repl...

Antibiotic resistance in microbes
The treatment of infectious disease is compromised by the development of antibiotic-resistant strains of microbial pathogens. A variety of biochemical processes are involved that may keep antibiotics out of t...

Improvement of Barley and Wheat Quality by Genetic Engineering
Although the mature cereal grain consists predominately of starch with only about 10–15% of protein, it is the protein fraction which is largely responsible for quality. In the case of wheat the quality for br...

Evidence for a diurnal horizontal migration in Daphnia hyalina lacustris Sars
Diurnal sampling of a transect across a shallow, eutrophic gravel pit suggested that a diurnal horizontal migration was present in Daphnia hyalina lacustris, in which it remained in the littoral zone during the d...

Decay rates and nitrogen dynamics of decomposing watercress (Nasturtium officinale R.Br.)
We examined the decomposition of watercress in the laboratory at 10° and 20 °C, and in the field. Rates varied from 0.058 g g−1 day−1 in the laboratory to 0.115 g g−1 day−1 in the field. There was a rapid generat...

Recent Advances in the Pharmacology of Excitatory Amino Acids in the Mammalian Central Nervous System
Current ideas are described on the classification of excitatory amino acid receptors in the mammalian central nervous system. The actions of some new agonists and antagonists for NMA receptors and non-NMA rece...

Effects of D-α-aminoadipate on physiologically evoked responses of cat dorsal horn neurones
Microelectrophoretic administration of D-α-aminoadipate reversibly reduced excitatory responses of cat dorsal horn neurones evoked by iontophoretic glutamate and non-noxious peripheral stimuli but did not infl...

A genetic and biochemical study of streptomycin-and spectinomycin-resistance in Salmonella typhimurium
In Salmonella typhimurium, streptomycin resistance can occur by mutation at the strA or the strB mutants have altered ribosomes which are refractory to the drug in cell-free amino acid incorporation systems, and ...
