Neuroendocrine-specific protein (NSP) -reticulons are endoplasmic reticulum-associated protein complexes, which are localized in the endoplasmic reticulum (ER) and identified as markers for neuroendocrine differentiation. In the present study, human reticulon 3 gene (hRTN3) was cloned and its expression pattern in a variety of tissues was investigated. Truncated hRTN3s corresponding to the C-terminal (hRTN3-C) domain were expressed and purified. hRTN3 mRNA was down-regulated during the differentiation of human neuroblastoma cell line SH-SY5Y induced by all-trans-retinoic acid (RA), which suggests that, like other members of the reticulon family, hRTN3 is a potential marker for neuroendocrine differentiation.

Implanted biomaterials have transformed healthcare and the treatment of injury and disease,but their infuence on the local immune landscape remains *** we discovered that degradation-resistant titanium-based implants establish an immunosuppressive microenvironment by recruiting myeloid cells,including monocytes,macrophages,neutrophils,and myeloid-lineage dendritic *** normal tissues,the tissues nearby implants exhibit an chronic inflamed and immunosuppressive status characterised by myeloid-rich,T cell-exhaustion gene signature by single-cell RNA *** C treatment provides an effective strategy to rescue the immunosuppressive microenvironment,which can be used as a regular supplement to reduce the risk of malignant cell survival around the implants.

The effect of Sn concentration on the superconducting properties and structure of YBa_(2)Cu_(3-x)Sn_(x)O_(7-y) system were systematically *** zero resistance temperature was found to be above 90K as z ranges from 0 to *** x>1.3,the system exhibited no superconducting properties at liquid nitrogen *** results of X-ray diffraction showed a regular pattern of mixed structures of 123 phase and a new phase in the system with the increase of Sn *** analysis suggested that the new phase might be BaSnO3 with deformed perovskite structure and about 6% of Cu were substituted by Sn in the 123 phase at x=*** is therefore likely that the new phase modulates the structure of 123 phase and stabilize the 123 *** the Sn atoms enter 123 phase and occupy the Cu sites in the Cu-O chain and break the chain,the system remains with Tc>***,the Cu-O chain plays a less important role in the high-Tc superconductivity.

Background L-shaped incision of pronator quadratus （PQ） muscle along its radial and distal borders was always taken for distal radius fractures reduction and internal *** of the PQ muscle was always recommended at the end of operation for some instructive *** repair of PQ is not satisfied because of poor quality of muscle and fascial tissues which may cause pain or impede forearm pronation and supination for post-operative scarring around *** the locking palmar plate to pass under the pronator quadratus muscle and the locking screws are inserted through miniincisions in pronator quadratus in some patients with distal radius fractures is a reasonable technique which can preserve the pronator *** purpose of this study was to evaluate and compare the clinical effects after volar plating of the distal radius fractures while preserving the pronator quadratus and pronator quadratus *** Between September 2010 and April 2012,65 patients （42 males and 23 females; aged 20-68 years and a mean age of 42.5 years） with distal radius fracture underwent open reduction and internal fixation using the volar locking palmar plates （Depuy or Smith companies）.The patients were classified as 23A-2 through 23C-3 according to the Orthopaedic Trauma Association （OTA） *** surgeries were completed by the same trained *** volar locking palmar plates of distal radius performed with preserving pronator quadratus group involved 30 patients including 19 males and 11 females and performed with pronator quadratus repair group involved 35 patients including 23 males and 12 *** compared the two groups for wrist pain,forearm range of motion,grip strength,pedoperative complications and wrist functional recovery *** The minimum follow-up for the whole cohort was one *** differences between the two groups were significant with regard to wrist pain,forearm range of motion,grip strength and wrist function at 1,2,and
