Metastable Austenitic Steel Structure and Mechanical Properties Evolution in the Process of Cold Radial Forging.

The article presents the influence of structure formation on the properties of 321 metastable austenitic stainless steel in the process of cold radial forging (CRF). The steel under study after austenitization was subjected to CRF at room temperature with degrees of true strain (e) 0.26, 0.

[Selective adsorption of endotoxin in the complex treatment of patients with severe sepsis].

Severe sepsis and septic shock remain the most serious problem of critical care medicine today with a mortality of 25-80%. Bacterial endotoxin is of considerable importance in the pathogenesis of sepsis. A selective hemosorbent in which endotoxin adsorption is accomplished via its binding to a synthetic peptide (LPS-A) has been recently designed in Sweden.

[Disturbances of bone tissue metabolism in elderly and senile patients after stomach resection].

The authors have examined 104 elderly patients after one of operations on the stomach. The mineral metabolism, biochemical and X-ray findings were investigated. Osteoporosis was observed more often in patients after Billroth-II resection of the stomach, rarer after Billroth-I operation and more rarely in patients after pylorus-saving resection of the stomach.

[High homology of plasmids carrying class II restriction modification systems, EcoRV isoschizomers, and their prevalence in natural Escherichia coli strains].

Screening of 660 clinical Enterbacteriaceae strains from the collection of L. V. Gromashevsky Kiev Institute of Epidemiology and Infectious Diseases for specific endonuclear activity revealed site-specific endonucleases, EcoRV isoschizomers in 6 E.
