Relation between Self-Organization and Wear Mechanisms of Diamond Films.

The study deals with tribological properties of diamond films that were tested under reciprocal sliding conditions against SiN balls. Adhesive and abrasive wear are explained in terms of nonequilibrium thermodynamic model of friction and wear. Surface roughness alteration and film deformation induce instabilities in the tribological system, therefore self-organization can occur.

DNA adducts as biomarkers for oxidative and genotoxic stress from pesticides in crop plants.

Plant studies have been carried out to identify the nature and extent of the formation of adducts with DNA bases when treated with pesticide formulations. DNA extracted from crop plants after treatment with pesticide formulations has yielded evidence of adduct formation. The extent of DNA modification has been established by (32)P postlabeling studies.

Effect of high-frequency low-intensity irradiation on reproductive function in C57Bl/6 and randombred mice.

The effect of high-frequency low-intensity radiation on reproductive function was studied on C57Bl/6 and randombred mice. We revealed a progressive decrease in the number of offspring, prevalence of males over females in all generations, and the appearance of stillbirths. The decrease in the number of offspring was probably related to increased number of homozygotes and decreased number of heterozygotes in the population under the influence of nonthermal radiation.

Regulation of proteolytic activity of pepsin in rats [correction of mice] by rotating electromagnetic field.

In experiments on Wistar rats we studied the effect of low-frequency electromagnetic field rotating in either right-handed or a left-handed sense on proteolytic activity of pepsin. The right-handed rotating field increased, while left-handed rotating field decreased pepsin activity. Possible mechanisms of these changes in pepsin activity are discussed.

Exposure to low-intensive superhigh frequency electromagnetic field as a factor of carcinogenesis in experimental animals.

Inbred albino mice and C57Bl/6 mice were exposed to nonthermal radiation of 37 GHz frequency in order to detect delayed effects caused by repeated irradiation. The detected pathomorphological changes and the dynamics of their formation suggest that these factors are responsible for delayed formation of immunodeficiency provoking mutagenic and carcinogenic effects.
