Endoscopy revealed haemorrhagic gastritis. Laboratory evidence of influenza A(H1N1) virus infection was present. Two children died as a result of their illness. The association of(More)
When two strains of phage T5 (heat-susceptible form T5st(+) and its heat-resistant mutant T5st) were placed in solutions containing various high concentrations of chelating agents (sodium citrate and ethylenediaminetetraacetic acid) at room temperature, they could be effectively inactivated by rapid dilution in distilled water of relatively low temperatures(More)
The present study of a typical proteolytic enzyme extends the quantitative investigations previously reported from this laboratory on the effects of pressure on protein systems in viva (1) and in vitro (2). This paper presents new data on the self-digestion of trypsin and the digestion of casein by trypsin; a forthcoming paper will discuss the effects of(More)
