Production of biphenomycin A by Streptomyces griseorubiginosus 43708 was stimulated by a mixed culture with a partner strain, Pseudomonas maltophilia 1928. This stimulatory effect on biphenomycin A accumulation by the mixed culture was caused by the enzyme activity which strain 1928 possessed. It is suggested that in a mixed culture strain 43708 produces a precursor of biphenomycin A in culture...

The relation between science and religion is often discussed in the media — what are your views? For the large majority of scientists, religion has no direct impact on their research and this is not an issue that concerns them. But I don’t believe that we should pretend that science and religion are ‘compatible’: they are actually diametrically opposed ways of thinking and acquiring knowledge. ...

IN previous work it has been shown that insulin, injected into the normal animal, reduces the amino-nitrogen content of the blood and tissues [Luck et al., 1928; Kiech and Luck, 1928], the latter even though hypoglyeaemia be prevented by the simultaneous administration of glucose [Luck and Spaulding, 1928-29]. The rate of urea formation is also increased. More and more we have come to believe t...

rofessor Werner Felix Dutz (Figure 1), an Austrian pathologist, joined the faculty of the School of Medicine of Shiraz University in southern Iran in 1959.

The pioneering cancer cytogeneticist, Peter C. Nowell, died on December 26, 2016, from complications of Alzheimer’s disease at the age of 88. His work laid the foundation for the recognition of the genetic basis of cancer that paved the way for modern targeted cancer therapeutics. Nowell’s observations of changes in chromosomal anatomy during progression of malignancies led him to predict that ...

Passé les récits épiques premiers héros l’aventure « », historiens se sont montrés plus critiques, circonspects, voire méfiants ou réprobateurs. Serions-nous face mythe construit toutes pièces Certes, l’unité d...
