Developing translational nanoradiosensitizers with multiple activities in sensitizing tumor cells and re-shaping tumor immunosuppressive microenvironments are urgently desired for addressing the poor therapeutic efficacy of radiotherapy in clinic. Inspired by the anaerobic and immunoagonist properties of the probiotic (bifidobacterium longum, BL), herein, a biomimetic Selenium nanoradiosensitizer in situ-formed on the surface of the probiotic (BL@SeNPs) is developed in a facile method to potentiate radiotherapy. BL@SeNPs selectively target to hypoxia regions of tumors and then anchor on the surface of tumor cells to inhibit its proliferation.

Women-identifying and women+ gender faculty (hereto described as women+ faculty) face numerous barriers to career advancement in medicine and biomedical sciences. Despite accumulating evidence that career development programming for women+ is critical for professional advancement and well-being, accessibility of these programs is generally limited to small cohorts, only offered to specific disciplines, or otherwise entirely unavailable. Opportunities for additional, targeted career development activities are imperative in developing and retaining women+ faculty.

Group A basic leucine zipper (bZIP) transcription factors play critical roles in abscisic acid (ABA) signaling and plant development. In Arabidopsis thaliana, these factors are defined by a highly conserved core bZIP domain, and four conserved domains throughout their length: three at the N-terminus (C1 to C3) and a phosphorylatable C-terminal SAP motif located at the C4 domain. Initially, members such as ABI5 and ABFs were studied for their roles in ABA signaling during seed germination or stress responses.

A Japanese woman with Li-Fraumeni syndrome in her 40s underwent comprehensive genetic profiling accompanied by germline data using the Oncoguide NCC Oncopanel, but no germline pathogenic variants in the tumor suppressor gene TP53 were detected. However, careful examination of additional data in the report suggested the presence of a large TP53 deletion. Custom targeting next-generation sequencing and nanopore sequencing revealed a 3.

The three SDEs of CLas were expressed in citrus leaves by AuNPs-PEI mediated transient expression system, and promoted the proliferation of CLas and inhibited citrus immunity. Huanglongbing (HLB) is the most severe bacterial disease of citrus caused by Candidatus Liberibacter asiaticus (CLas). CLas suppress host immune responses and promote infection by sec-dependent effectors (SDEs), thus insight into HLB pathogenesis is urgently needed to develop effective management strategies.
