Seven strains of Pseudomona aeruginosa isolated from hospital environmental surfaces were characterized in order to test their ability to produce to different antibiotic resistance and heavy metal concentration, biosurfactants, pyocyanin, biofilms, as well as to measure their tolerance, growth on various carbon sources, antimicrobial resistance and resistance to heavy metals. hemolytic profile, all strains produced mono and dirhamnolipids. When using the method known as Kirby Bauer, strains showed resistance to antibiotic (ampicillin, amoxicillin, cefotaxime, ceftazidime, amikacin and imipenem).

DNMT3B modulates the expression of cancer-related genes and downregulates the expression of the gene VAV3 via methylation Peralta Arrieta, Irlanda; Hernández Sotelo, Daniel; Castro Coronel, Yaneth; Leyva Vázquez, Marco Antonio; Illades Aguiar, Berenice (American Journal of Cancer Research, 2017)Altered promoter DNA methylation is one of the most important epigenetic abnormalities in human cancer. DNMT3B, de novo methyltransferase, is clearly related to abnormal methylation of tumour suppressor genes, DNA repair ...
