چکیده
Addition of the four deoxyribonucleosides in vitro to 6C3HED mouse ascites tumor stimulates 32P incorporation into DNA and depresses incorporation into RNA at concentrations greater than 10~4 M. The four ribonucleosides stimulate incorporation into both DNA and RNA. Hydroxyurea blocks the ribonucleoside stimulation of 32P incorporation into DNA but not RNA. The inhibition of 32P incorporation into DNA by hydroxyurea

Background Nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. Although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. In the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase acti...
متن کاملMechanism of Calf thymus DNA radioprotection by sucrose: A combined effect of scavenging action and altered water
Background: Development of safe radioprotector is a challenging task. In this study radioprotective effect of sucrose has been demonstrated in calf thymus DNA (CtDNA). Sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around DNA and effects of radiation on DNA. Hoechst 33258 was used to probe the possible alteration in physicochemical p...

In this study, an organic compound inhibitor, namely N-benzyl-N-(4-chlorophenyl)-1H-tetrazole-5-amine (NBTA), was synthesized and the role of this inhibitor for corrosion protection of stainless steel (SS) exposed to 0.5 M H2SO4 was investigated using electrochemical, and quantum analysis. By taking advantage of potentiodynamic polarization, the inhibitory action of NBTA was found t...
متن کاملFipronil: mechanisms of action on various organisms and future relevance for animal models studies
Because insects had developed resistance to several insecticides, today, neonicotinoids and fiproles are used to combat pests. The difference between this two classes of insecticides is that fipronil acts by inhibiting the receptors of nervous cells, while neonicotinoids perturbs the neuronal transmission. The suitable properties of fipronil make that its use to be more obvious on the pesticide...
