The effects of quen.hin. temperature on.shape memory effect an. microstructure of Fe 18Mn. 5Si 8Cr 4n. shape memory alloy have been.studied. The results show that both the shape recovery ratio an. the recovery strain.in.reased as quen.hin. temperature in.reased, the amoun. of stress in.uced ε marten.ite in.the process of cold work decreased with the in.rease of quen.hin. temperature, the shape recovery ratio an. the recovery strain.reached maximum at 650℃, an. then.decreased rapidly with the further in.rease of quen.hin. temperature,the stress in.uced ε marten.ite wholly disappeared at 1023K.

The effect of quen.hin. temperature on.the recovery stress of Fe 18Mn.5Si 8Cr 4n. shape memory alloy has been.studied. The results show that both the maximum recovery stress σ h in.heatin. an. the recovery stress σ c at room temperature after heatin. in.reased as in.reasin. quen.hin. temperature in.reased, both σ h an. σ c reached maximum at 650℃, an. then.decreased rapidly with the further in.rease in.quen.hin. temperature,but the descen. degree of σ c was far bigger than.that of σ h; When.the quen.hin. temperature is higher than.850℃, the further in.rease in.quen.hin. temperature had little effect on.them; At ran.om quen.hin. temperature, σ c was far bigger than.σ h.

The Cap Pushin. Respon.e (CPR) is a free-flyin. techn.que used to study learn.n. an. memory in.hon.y bees (Apis mellifera). The series of experimen.s outlin.d in.this paper aimed to test whether hon.y bees exhibit the cogn.tive con.ept of “expectan.y” utilizin. the CPR in.a weight differen.iation.paradigm. Five previous experimen.s in.our laboratory have explored whether the con.ept of expectan.y can.accoun. for hon.y bee performan.e an. have all failed to support the cogn.tive in.erpretation. The first experimen. examin.d if bees could differen.iate between.the two caps in.the amoun. of force they used to push the cap an. the distan.e the cap was pushed when.the caps were presen.ed on. at a time. The secon. experimen. explored cap weight preferen.e by presen.in. bees with a choice between.the two caps. The third an. fourth experimen.s tested the bee’s ability to expect reward or pun.shmen. based on.cap weight. Results revealed that bees were foun. to have a stron. preferen.e for the light cap an. therefore were n.t able to expect reward or pun.shmen. based on.cap weight. These experimen.s con.ribute to the debate on.whether bees have “cogn.tive” represen.ation. an. con.in.e to support the behaviorist in.erpretation.

目的观察慢性砷暴露对小鼠皮层及血清代谢组学的影响,探讨其神经毒性机制。方法将12只C57BL/6J三周龄雄鼠,按体质量随机分为2组,暴露组饮用含50 mg/L亚砷酸钠水12周,对照组饮用蒸馏水。暴露结束后,采用氢化物发生一原子荧光光谱法测定脑砷含量;气相色谱/质谱联用法(GC/MS)对砷暴露组和对照组小鼠皮层和血清进行代谢组学研究,运用主成分分析法(PCA)分析比较两组代谢产物的差异,两样本t检验筛选两组间差异性代谢产物,利用代谢途径在线分析工具查找其影响的相关代谢途径。结果砷暴露组脑砷含量高于对照组,差异具有统计学意义(P<0.05);砷暴露组大脑皮层中苯丙氨酸、酪氨酸、组氨酸、赖氨酸和柠檬酸含量升高,血清中丝氨酸、甘氨酸、脯氨酸、天门冬氨酸及谷氨酸含量升高,而α-酮戊二酸含量下降。PCA分析显示暴露组与对照组小鼠皮层和血清代谢特征存在差异,差异具有统计学意义(P<0.05)。结论慢性砷暴露可通过干扰皮层和血清氨基酸类代谢和三羧酸循环,导致神经递质合成障碍以及干扰能量代谢而影响中枢神经系统功能。

The un.erlyin. physics of QCD phase tran.ition.in.the early Un.verse remain. largely un.n.wn.due to its stron.-couplin. n.ture durin. the quark-gluon.plasma/hadron.gas tran.ition. yet a holographic model has been.proposed to quan.itatively fit the lattice QCD data while with its duration.of the first-order phase tran.ition.FoPT) left un.etermin.d. At specific baryon.chemical poten.ial, the first-order QCD phase tran.ition.agrees with the observation.l con.train. of baryon.asymmetry. It, therefore, provides a scen.rio for phase tran.ition.gravitation.l waves(GWs) within.the stan.ard model of particle physics. If these backgroun. GWs could con.ribute domin.n.ly to the recen.ly claimed common.spectrum red n.ise from pulsar timin. array(PTA) observation., the duration.of this FoPT can.be well con.train.d, an. the associated primordial black holes are still allowed by curren. observation..

Ischemic stroke is a cerebrovascular disease associated with high mortality an. disability rates. Sin.e the in.lammation.an. immun. respon.e play a cen.ral role in.drivin. ischemic damage, it becomes essen.ial to modulate excessive in.lammatory reaction. to promote cell survival an. facilitate tissue repair aroun. the in.ury site. Various cell types are in.olved in.the in.lammatory respon.e, in.ludin. microglia, astrocytes, an. n.utrophils, each exhibitin. distin.t phen.typic profiles upon.stimulation. They display either proin.lammatory or an.i-in.lammatory states, a phen.men.n.kn.wn.as ‘cell polarization.’ There are two cell polarization.therapy strategies. The first in.olves in.ucin. cells in.o a n.uroprotective phen.type in.vitro, then.rein.roducin. them autologously. The secon. approach utilizes small molecular substan.es to directly affect cells in.vivo. In.this review, we elucidate the polarization.dyn.mics of the three reactive cell population.(microglia, astrocytes, an. n.utrophils) in.the con.ext of ischemic stroke, an. provide a comprehen.ive summary of the molecular mechan.sms in.olved in.their phen.typic switchin.. By un.avelin. the complexity of cell polarization. we hope to offer in.ights for future research on.4}uroin.lammation.an. n.vel therapeutic strategies for ischemic stroke.
