LanducciAbstractEthnopharmacological relevanceMikania glomerata Spreng. (MG) and Mikania laevigata Sch. Bip. ex Baker (ML), popularly known as guaco, are medicinal plants similar in morphology, chemical composition and medicinal uses. Both species are often used and sold without distinction; however, it is believed that their chemical composition is different.AimThus, the aim of this study is to investigate if the aqueous extract of MG and ML present similar anti-inflammatory activity to the point of being used interchangeably.Material and MethodsDifferent doses of both extracts and coumarin were given to rats in different experimental models to assess the anti-inflammatory activity between these two species. For this, the animals were submitted to paw edema, pleurisy and degranulation of peritoneal mast cell and the extracts were also characterized by Ultra High Efficiency Liquid Chromatography coupled to Mass Spectrometry (UHPLC-MS).ResultsThe chromatographic method showed that ML presents ten times more coumarin than MG. Oral administration of MG, ML and coumarin inhibited paw edema induced by carrageenan (400 mg/kg, 55% inhibition; 400 mg/kg, 57% inhibition; 75 mg/kg, 38% inhibition; p

KidderAbstractEpigenetic regulation of chromatin plays a critical role in controlling stem cell function and tumorigenesis. The histone lysine demethylase, KDM5B, which catalyzes the demethylation of histone 3 lysine 4 (H3K4), is important for embryonic stem (ES) cell differentiation, and is a critical regulator of the H3K4-methylome during early mouse embryonic pre-implantation stage development. KDM5B is also overexpressed, amplified, or mutated in many cancer types. In cancer cells, KDM5B regulates e...

Hodge, David Bosler, Lauren Rubinstein, Navid Sadri, Shashirekha ShettyAbstractThe inv(3)(q21q26.2) altering a single chromosome 3 homolog is an established myeloid malignancy-associated entity. Comparatively, double inv(3) cases involving both homologs are exceedingly rare with 13 reports across AML, CML and MDS. This scarcity was confirmed by finding only 2 new cases out of 34,898 bone marrows collected during a 55 year period at a large medical center (0.0005%). The double inv(3) was detected by karyotype and confirmed by FI...
