[SURGICALLY CAUSED INJURY AND WOUND-HEALING PROPERTIES OF BETULIN (EXPERIMENTAL STUDY)].

According to the experimental data a triterpene alcohol betulin have anti-inflammatory, wound- and burn-healing activity. Previous data reports, that betulin was used in not less than 5% concentrations. That is why studying less concentrations is of major interest.

Pattern of clinically relevant mutations in consecutive series of Russian colorectal cancer patients.

One hundred and ninety-five consecutive surgically treated Russian colorectal cancer (CRC) patients were retrospectively analyzed for the presence of mutations in KRAS, NRAS, BRAF and PIK3CA genes as well as for the microsatellite instability status. Comparison between high-resolution melting analysis, co-amplification at lower denaturation temperature PCR, DNA sequencing and allele-specific PCR for the detection of KRAS codon 12/13 mutations revealed that none of these methods alone provided satisfactory results in 100 % of the analyzed cases; this experience supports the use of more than one mutation-detecting technique at least in some circumstances. KRAS codon 12/13 substitutions were detected in 70 (35.
