Accumulation, functional and antioxidant responses to acute exposure to Di(2-ethylhexyl)phthalate (DEHP) in Mytilus galloprovincialis.

Mussels were exposed to di-(2-ethylhexyl) phthalate (DEHP) (0.4 mg L and 4.0 mg L) for 24 h and 48 h and its effect on hemocyte cellular composition and spontaneous reactive oxygen production (ROS) levels in hemocytes were evaluated.

Deletions in Mitochondrial DNA from the Peripheral Blood of Mayak PA Workers Exposed to Long-Term Ionizing Radiation.

The number of large deletions of mitochondrial DNA in whole peripheral blood of the former Mayak PA workers occupationally exposed to prolonged γ-radiation has been determined in the long term period after irradiation (mean cumulative dose 135.40 ± 22.03 cGy, age range at the time of blood sampling 67-76 years) and compared with the number of deletions in groups of "young" (19-33 years) and "adult" (66-73 years) individuals who had no contact with radiation sources.

[Microbial Processes and Genesis of Methane Gas Jets in the Coastal Areas of the Crimea Peninsula].

Hydroasoustic techniques were used for detection and mapping of gas jet areas in the coastal regions of the Crimean peninsula. Gas seep areas in the bays Laspi, Khersones, and Kazach'ya were chosen for detailed microbiological investigation. The first type of gas jets, observed in the Laspi Bay, was probably associated with discarge of deep thermogenic methane along the faults.

[Sulfate reduction and microbial processes of the methane cycle in the sediments of the Sevastopol bay].

The rates of microbial processes of sulfate reduction and of the methane cycle were measured in the bottom sediments of the Sevastopol basin, where seeps of gaseous methane have been previously found. Typically for marine environments, sulfate reduction played the major role in the terminal phase of decomposition of organic matter (OM) in reduced sediments of this area. The rate of this process depended on the amount of available OM.

[Specialized software product for comparative analysis of multicomponent DNA fingerprints].

"GelAnalyzer" software, which is used to identify and correctly compare DNA fingerprints consisting of a large number of discrete bands, has been developed by the project to study the quantitative changes in DNA polymorphism patterns in animals and humans exposed to gamma radiation. The actual capabilities of this program are much broader and include the possibility to analyze the images of any multicomponent gels containing fragments of DNA, RNA, and proteins. This software product runs on Windows.
