BACKGROUND A truly noninvasive glucose-sensing device could revolutionalize diabetes treatment by leading to improved compliance with recommended glucose levels, thus reducing the long-term complications and cost of diabetes. Herein, we present the technology and evaluate the efficacy of a truly noninvasive device for continuous blood glucose monitoring,… (More)
The elasticity modulus of Escherichia coli cell walls was found to change in the course of growth of the culture. It decreased in the middle of the exponential phase, apparently as a result of intensification of biosynthetic and related to them transport processes at this period. If the cells were treated with EDTA, their elasticity modulus was lower, by an… (More)
Vesicular bodies are observed during enzymatic degradation of the yeast cell wall and in the course of wall regeneration. In both cases various types of vesicles are formed and exocytated by different mechanisms. They are characterized cytochemically and their possible role in cell wall regeneration is discussed.
The interaction of a parasite with a host was studied in the two-membered bacterial system, Bdellovibrio bacteriovorus 109D and Escherichia coli B, immobilised in polyacrylamide gel (PAAG). The parasite localised inside the host cells was found to be more resistant to the toxic action of PAAG components than free B. bacteriovorus. The latter lost its… (More)
The effect of the bacteriolytic preparation "Lysoamidase" on Staphylococcus aureus 299 P was studied. The maximum activity of the preparation was observed at pH 8.0 ionic strength 0.01-0.02 M and 50-60 degrees of the incubation medium. The electron microscopic examination revealed that "Lysoamidase" hydrolyzed the cell wall in one or several points with the… (More)
As was demonstrated using the Con-A polymer, membranous fractions prepared by various cell disintegration procedures are a heterogeneous population. The population includes right side out vesicles and inside out vesicles whose proportion depends on the procedure of disintegration. The orientation of these vesicles was studied by electron microscopy, their… (More)
