This paper describes the information that permits one to determine the origin of the legend that there were 6000 books in D.M. Golitsyn's library. Fragmentary information was found using the Internet directly on sites, in digitized book editions and the descriptions of archival file, as well as in printed publications, whose bibliographic descriptions were found on the Internet. An attempt was made to determine the possible size of D.M. Golitsyn's library. The article describes how the Internet was used to reveal little-known information from the history of Russian private libraries while subsequently gaining new information on them by complex data analysis.

We measured the level of cardiac markers (high-sensitivity troponin T and MB fraction of creatine kinase) in children of the first year of life with congenital heart disease in the perioperative period. After cardiac surgery, plasma levels of the above markers exceed the reference limits in the examined children. The diagnosis of myocardial ischemia using biochemical markers in the postoperative period is possible only by dynamic monitoring of the cardiac marker level. The preoperative concentration of high-sensitivity troponin T in children of the first year of life with congenital heart disease can be regarded as a predictor of postoperative complications.

This paper describes information on the libraries of A.P. Volynskii and his adherents, which was gained from interactive sources and some printed publications. It reveals the disagreement in the data from the chronicle of the LAS and other information sources, as well as that between different printed and electronic sources. Web sites, electronic copies of books by S.A. Belokurov, D.A. Korsakov, and V.S. Ikonnikov, the fourth volume of Materials on the History of the Imperial Academy of Sciences, electronic documents, and indices of stocks for the Russian State Archive of Ancient Acts and the St. Petersburg Department of the Archive of the RAS were used as information sources from the Internet. A part of the cited data was obtained using the "Search for Books. Browsing a Fragment" Google DB subsystem.

Additional information obtained by means of the Rambler, Yandex, and Google web search engines is added to the data on the collection formation of the Library of the Russian Academy of Sciences from 1714 to 1736, which was published in LRAS Chronicles, vol. 1. The significance of the private libraries that formed the basis for the formation of the collection of BAN until 1737 is characterized. Printed and electronic scientific publications, which may serve as information sources on this topic, are presented.

We present the results of treatment of chronic ischemia of the lower extremities (distal form) with angiogenesis stimulators, autologous endothelioblast precursors (CD133+) and gene preparation of vascular endothelial growth factor VEGF165 (angiostimulin). Good clinical effect was attained in all patients, which was confirmed instrumentally 1, 3, and 6 months after administration of the stimulant: transcutaneous oxygen tension on the foot, index of malleolar pressure, and walking duration increased, parameters of microcirculation improved, the number of newly formed collateral arteries increased (angiography findings), quality of life improved (SF 36 questionnaire), and parameters of coagulogram also improved. The maximum positive dynamics was observed by month 3 of the study.

A comparative characteristic of the rheological properties of blood and the state of peripheral blood flow in patients with hypertrophic obstructive cardiomyopathy is presented. 48% of the patients had marked disturbances of the rheological properties of blood. It is shown that disturbances of microcirculation are in many respects due to the changes in the viscosity indices of erythrocytes and plasma.

A new cardioplegic solution based on three natural dipeptides was developed and introduced at the Laboratory of Cardioplegia, A. N. Bakulev Research Center of Cardiovascular Surgery. The electrolyte composition of the solution corresponded to the category of intracellular cardioplegic solutions. The results of 60 experiments on isolated rat hearts were analyzed for choosing the optimal concentration of sodium ions (35, 60, or 80 mmol/liter). The composition of the studied cardioplegic solutions was selected by ion concentrations in the intra- and extracellular fluid. Earlier and most effective recovery of cardiac function with minimum rhythm and conductivity disorders was observed in the group treated with cardioplegic solution with sodium ion concentration of 60 mmol/liter.
