Angiosarcoma of the colon is rare, as is colonic amyloidosis.To our knowledge, there have been no reported cases of angiosarcoma arising in association with amyloid deposition.Herein, we described a case of 77-year-old man who presented with hematochezia, and a sigmoid mass was found on colonoscopy.Histologic examination of the Round Dining Table r
Four colonies of the stingless bee Partamona cupira (Hymenoptera: Apidae) were cytogenetically analyzed using conventional staining and the fluorochromes Toy Trains CMA3 e DAPI.The females have 2n = 34 chromosomes (2K=32+2).Some females, however, presented an additional large B acrocentric chromosome, to a total of 2n = 35.Chromosome B and the chro
Materials capable of circularly polarized luminescence (CPL) have attracted considerable attention for their promising potential applications.Bacterial cellulose (BC) was characterized as having a stable right-handed twist, which makes it a potential chiral host to endow luminophores with CPL.Then, the CPL-active BC composite film was constructed b
