Abstract: The present disclosure provides a clamping assembly, a clamping device, a gimbal and a stabilizer. The clamping assembly (100) includes a supporting member (110), having a snap-fit groove (111); and a clamping member (160), configured to clamp the mobile device (500), wherein the clamping member (160) includes a snap-fit structure that is detachably snap-fitted with the snap-fit groove (111), the clamping member (160) is detachably connected with the supporting member (110), which is not only reliable in connection, but also does not require disassembly and assembly of screws, so that the stability of the clamping device for clamping the mobile device and the operation convenience can be improved.

Abstract: Human pluripotent stem cells (hPSCs) are promising cell source to produce therapeutic endocrine cells for diabetes treatment. A gel solution made by decellularized tissue-specific extracellular matrix (dpECM) significantly promotes three-dimensional (3D) islet-like organogenesis during induced hPSC differentiation into endocrine lineages. Islet organoids are self-organized even in a two-dimensional (2D) culture mode. Cells derived from hPSCs differentiated on such ECM coated substrates exhibit similar cellular composition to native pancreatic islets. These cells express islet signature markers insulin, PDX-1, C-peptide, MafA, glucagon, somatostatin, and pancreatic polypeptide, and secrete more insulin in response to glucose level compared to a traditional matrix substrate (Matrigel). The dpECM facilitates generating more C-peptide+/glucagon? cells rather than C-peptide+/glucagon+ cells. Remarkably, dpECM also facilitated intra-organoid vascularity by generating endothelial cells and pericytes.

Abstract: A cancer vaccine technology is provided which knocks out expression of cell surface immune checkpoint proteins, to facilitate their processing by immune cells, and optionally by knocking-in the expression of cytokines to boost immune response. Non-replicating tumor cells lacking cell surface CD47 are highly effective immunizing agents against subcutaneous mouse melanoma. Whole-cell vaccines inhibited tumor growth, and immunophenotyping showed a dramatic increase in activated effector cell subsets and M1-type macrophages aided by a significant reduction in the tumor-associated macrophage and myeloid derived suppressor cell compartments. A remarkable downregulation of cell surface CD47 was observed in the tumors that did escape after vaccination with genetically modified cells, suggesting the intricate involvement of CD47 in a prophylactic situation. An effective vaccination strategy to increase tumor-specific immune response in solid tumors is provided to improve the outcome of cancer immunotherapy.

Abstract: We describe here the development and optimization of an embodiment of a new serologic EIAV diagnostic ELISA assay to detect serum antibodies to the EIAV S2 protein that are produced in infected horses, but not in horses inoculated with the EIAVUK?S2 vaccine virus. An embodiment of the test S2 protein antigen was developed using the S2 gene sequence from the EIAVUK strain of virus and a series of modifications to facilitate production and purification of the diagnostic antigen, designated HS2G. Using this embodiment of an HS2G as antigen, we describe the development of an affinity ELISA (NN-ELISA) that provides a sensitive and specific detection of S2-specific serum antibodies in experimentally and field infected horses (22/24), without detectable reactivity with immune serum from uninfected (12/12) or vaccinated (29/29) horses.
