4Thermal and Transmission Properties of UV Nonlinear Optical Material——ZnCd(SCN)_4 Crystal显示文摘Zinc cadmium thiocyanate(ZCTC), ZnCd(SCN) 4, has been discovered as a UV second order nonlinear optical coordination crystal. Its thermal and transmission properties are reported. The thermal decomposition is characterized by using the X ray powder diffraction (XRPD) and infrared (IR) spectroscopy at room temperature. The absorptions of intrinsic ions and ZCTC in a solution state are discussed as well as transmission properties of the ZCTC crystal. An effective method of reducing the surface reflection loss of ZCTC crystal is introduced.NING H X, XU D, WANG X Q, CHENG X F, YANG Z H (Institute of Cryst. Mater. and State Key Lab. of Cryst.

5Differentiation renders susceptibility to excitotoxicity in HT22 neurons显示文摘HT22 is an immortalized mouse hippocampal neuronal cell line that does not express cholinergic and glutamate receptors like mature hippocampal neurons in vivo.This in part prevents its use as a model for mature hippocampal neurons in memory-related studies.We now report that HT22 cells were appropriately induced to differentiate and possess properties similar to those of mature hippocampal neurons in vivo,such as becoming more glutamate-receptive and excitatory.Results showed that sensitivity of HT22 cells to glutamate-induced toxicity changed dramatically when comparing undifferentiated with differentiated cells,with the half-effective concentration for differentiated cells reducing approximately two orders of magnitude.Moreover,glutamate-induced toxicity in differentiated cells,but not undifferentiated cells,was inhibited by the N-methyl-Daspartate receptor antagonists MK-801 and memantine.Evidently,differentiated HT22 cells expressed N-methyl-D-aspartate receptors,while undifferentiated cells did not.Our experimental findings indicated that differentiation is important for immortalized cell lines to render post-mitotic neuronal properties,and that differentiated HT22 neurons represent a better model of hippocampal neurons than undifferentiated cells.Minchao He Jun Liu haowu Cheng Yigang Xing William Z Suo 2013Neural Regeneration Research2013,8,14:3
6Is tenecteplase ready to replace alteplase to treat acute ischaemic stroke? The knowns and unknowns显示文摘Tenecteplase(TNKase,TNK-tPA or TNK)is a thrombolytic agent derived from the tissue plasminogen activator(tPA).It is a 527-amino acid glycoprotein developed by replacing three amino acids at the T,N and K positions of the glycoprotein structure of tPA under genetic recombinant technology.After replacing threonine 103 with asparagine,asparagine 117 with glutamine and a tetra-alanine at amino acids 296–299,TNK is about eightfold more potent in dissolving clot,80-fold higher resistance to plasminogen activator inhibitor-1 and 14-fold enhanced relative fibrin specificity,and with a longer half-life(20 min).1 Hence,TNK is administered as a single intravenous bolus.Yi Dong Yi Sui Xin Cheng David Z Wang 2022Stroke & Vascular Neurology2022,7,1:3
