Mechanical strength and corrosion resistance are needed for Mg based BMs in the application of biomedical fields.In the present study, a high-strength biodegradable Mg-Gd alloys with an ultrafine microstructure successfully were prepared by equal channel angular pressing (ECAP).The high tensile strength of ECAPed Mg-Gd alloys was attributed to ultr
Campylobacter jejuni (C.jejuni) is considered as an opportunistic zoonotic pathogen that may cause gastroenteritis in humans and other Vacuum Bags animals.Wild birds may be as potential vectors of C.jejuni around urban and suburban areas.Here, 520 samples were collected from 33 wild bird species in urban and suburban areas, Beijing.In total 57 C.je
B cells surveil the body for foreign matter using their surface-expressed B cell antigen receptor (BCR), a tetrameric complex comprising a membrane-tethered antibody (mIg) that binds antigens and a signaling dimer (CD79AB) that conveys this interaction to the B cell.Recent cryogenic electron microscopy (cryo-EM) structures of IgM and IgG isotype BC
