[Prediction of the effectiveness of a health care organization system for Muscovites in case of scab].

The present paper gives data on prediction of the number of Muscovites and homeless individuals who suffered from scab in 1998-2005. As of 2005, the difference in the expected and actual number of scab patients among the Muscovites and the homeless was 4.3 and 13% less than the expected values, respectively.

[Nonchemical methods of modifying substrates for studying biopolymers with atomic force microscopy].

Two simple procedures of DNA molecule fixation on mica for following imaging by the atomic force microscopy were developed. The distinctive features of the procedures are their simplicity, absence of chemical modification stages, and the possibility to obtain the images in air under relative high humidity. Comparison of the features of the images obtained indicated that the procedures developed were competitive with the procedures earlier suggested.
