Dear Editor,Chromosomal translocations result from the interchange of geneticmaterial between non-homologous *** translocations are formed by erroneous repair of double-stranded breaks(DSBs)via non-homologous end joining(NHEJ)[1].Some genotoxic drugs produce DSBs and thus present a major risk factor for the development of oncogenic chromosomal *** risk factors that interfere with translocationprone DSB repair,once DSBs are already formed,are obscure,and potential effects of drugs on translocation formation during this step have never been explored.

Low temperature modification of barium borate, β-BaBO or BBO, is an exelent choice as an nonlinear optical crystal for harmonic generation in UV spectral range and construction of efficient optical parametric oscillators. The formation of finely polished surfaces is one from the key technology procedures in nonlinear device fabrication. The aim of present study is the complex analysis of structure and chemical composition of top layers of BBO optical surface prepared by mechanical polishing.
