[Are we ready for the growing threat of virus dependent cervical cancer and the initiation of screening in conditions of insurance medicine?].

The dynamics is presented of the rates of virus dependent diseases, in particular cervical cancer (CC), which are directly connected with the level of organization of screening and subsequent treatment of cancer. It is shown that in conditions of insurance medicine a reduction of examination rooms and female enrollment in cytology screening is observed. As a result, over the past 5 years, CC incidence in the Novgorod region increased 1.

[Biosynthesis of arachidonic acid by micromycetes (review)].

Arachidonic acid (ARA, 5,8,11,14-cis-eicosatetraenoic acid) is widely used in medicine, pharmaceutics, cosmetics, dietary nutrition, agriculture, and other fields. Microbiological production of ARA is of increased interest since the natural sources (pig liver, adrenal glands, and egg-yolk) cannot satisfy its growing requirements. Mechanisms for ARA biosynthesis as well as the regulation of enzymes involved in this process are considered.

[Mammographic screening: results and perspectives in evaluation of reproductive health and prevention of cancer].

8542 local women, aged over 40, were screened using digital high-sensitivity equipment. High incidence of hormonal dysfunction of the breast and other breast diseases in healthy subjects were reported (60.1% +/- 9.

[Bacterial strain characterizing by EDTA requirement].

A novel strain of bacteria (LPM-4) was isolated that is characterized by a unique EDTA requirement for cell growth. Suspensions of washed cells of strain LPM-4 degrated EDTA complexes with Ba2+, Mg 2+, Ca2+, and Mn2+ at constant rates (0.310-0.

[Bacterial degradation of EDTA].

Degradation of EDTA (ethylenediaminetetraacetic acid) or metal-EDTA complexes by cell suspensions of the bacterial strain DSM 9103 was studied. The activity of EDTA degradation was the highest in the phase of active cell growth and decreased considerably in the stationary phase, after substrate depletion in the medium. Exponential-phase cells were incubated in HEPES buffer (pH 7.
