Background: Among the alleles of the ABO system, cisAB and B(A) are the most intriguing due to their ability to encode a glycosyltransferase that can synthesize both A and B antigens. This dual activity leads to the formation of the AB phenotype, even in the presence of the O allele; resolution is achieved by molecular analyses.
Case Presentation And Methods: We describe herein a Brazilian family in which the mother (M42.
Human osteosarcoma (OS) is a rare tumor predominantly affecting long bones and characterized by a poor prognosis. Currently, the first line of intervention consists of the surgical resection of primary tumors combined with radiotherapy and chemotherapy, with a profound impact on the patient's life. Since the surgical removal of OS frequently results in a large resection of bones, the use of biomaterials to sustain the stability of the remaining tissue and to stimulate bone regeneration is challenging.

The chosen study area is Sicily (Italy), a region characterized by significant lithological heterogeneity. Eighty-three topsoil samples were collected at several sites away from potential anthropogenic pollution sources.
View Article and Find Full Text PDFA novel oxygen evolution reaction (OER) electrocatalyst was prepared by a synthesis strategy consisting of the solvothermal growth of NiS nanostructures on Ni foam, followed by hydrothermal incorporation of Fe species (Fe-NiS/Ni foam). This electrocatalyst displayed a low OER overpotential of 230 mV at 100 mA·cm, a low Tafel slope of 43 mV·dec, and constant performance at an industrially relevant current density (500 mA·cm) over 100 h in a 1.0 M KOH electrolyte, despite a minor loss of Fe in the process.
