Explants of rabbit lung parenchyma maintained in serumfree medium incorporate I 14Clproline and I Wllysine into collagen as I “Clhydroxyproline and I Wlhydroxylysine at a constant rate for at least 24 h. Evaluation of the size distribution of the [14Clhydroxyproline and [‘4Clhydroxylysine containing peptides within the explants demonstrated that 20 to 40% of the LY chains of newly synthesized c...

A guinea pig skin assay was developed as a measure of ileal loop fluid-inducing factor in the rabbit and possibly of the causative principle of Bacillus cereus food poisoning. A green or bloody necrotic reaction was produced in the guinea pig skin by injection of culture filtrates from 21 of 24 B. cereus strains tested, and by no other Bacillus species tested except for the closely related B. t...

A system is introduced that allows a string player to control a synthesis engine with the gestural skills he is used to. The implemented system is based on an electric viola and a synthesis engine that is directly controlled by the unanalysed audio signal of the instrument and indirectly by control parameters mapped to the synthesis engine. This method offers a highly string-specific playabilit...

Linear Predictive Coding (LPC) is a basic method used in speech signal processing. The purpose of this work is to implement a real-time LPC vocoder on a TMS320C6455 DSP board to assess the effect of the number of coefficients on sound quality for human voice, and bird and vehicle sounds. The experimental results show that there exists a threshold at which the sound quality is degraded. The thre...

much higher compared to hexokinase12. Although Lau et al. have provided convincing evidence for this switching effect in cells, its effect within whole organisms is not yet known. The switching hypothesis may open a new avenue for the understanding of growth factor receptor signaling by metabolic flux by way of the hexosamine pathway. The lattice model provided by Lau et al.1 is also intriguing...
