A THEORETICAL ESTIMATION OF PERFORMANCE PROPERTIES COATINGS BASED ON Fe-Cr-B-Si WITH LASER MELTING AND ALLOYING
The surface hardening of laser of powder coat the system Fe-Cr-B-Si to permit lower wear of the coat. The theory of resistence of wear of the laser based an analisis strengthening of interection of atoms complex particles of the powder and detail we showed the influence of the speed of ray and diameter of stain of the laser. The theory and experiments of BNTU (Minsk) showed satisfactorily agreement for the system Fe-Cr-B-Si. This theory is the base of nanotechnology of the laser.The surface hardening of laser of powder coat the system Fe-Cr-B-Si to permit lower wear of the coat.

BRCA-associated triple-negative breast cancer (TNBC) is characterized by high sensitivity to DNA-damaging cytotoxic drugs. The use of well-known BRCA1/2-specific antitumor agents β platinum derivatives and PARP inhibitors β has been discussed for a long time in the context of the treatment of metastatic BRCA-associated TNBC. Neoadjuvant regimens based on the use of anthracyclines and taxanes are the standard of drug therapy for primary BRCA-associated breast cancer. At present, there are few data regarding the addition of platinum drugs to anthracycline-taxane neoadjuvant chemotherapy in the treatment of primary BRCA-associated TNBC. This review details the various treatment options for both primary and metastatic BRCA-associated TNBC. It has been shown that the development of new strategies for the neoadjuvant chemotherapy of patients with primary BRCA-associated TNBC is an urgent clinical need to reduce the risks of recurrence and progression.BRCA-Π°ΡΡΠΎΡΠΈΠΈΡΠΎΠ²Π°Π½Π½ΡΠΉ ΡΡΠΈΠΆΠ΄Ρ Π½Π΅Π³Π°ΡΠΈΠ²Π½ΡΠΉ ΡΠ°ΠΊ ΠΌΠΎΠ»ΠΎΡΠ½ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ (Π’ΠΠ ΠΠ) Ρ
