Presented is a low noise interface circuit that is tuned to the needs of self-assembly monolayers biosensor SoC. The correlated double sampling(CDS) unit of the readout circuit can reduce 1/f noise, KTC noise and fixed noise of micro arrays effectively. The circuit is simulated in a 0.6 μm/level 7 standard CMOS process, and the simulated results show the output voltage has a good linearity with the transducing current of the micro arrays. This is a novel circuit including four amplifiers sharing a common half-circuit and the noise reducing CDS unit. It could be widely used for micro array biosensors.

目的:观察大豆异黄酮改善母鼠抑郁样行为的作用及其与血清雌二醇(E 2)、多巴胺(DA)及脑区雌激素受体β(ERβ)关系。方法:将产后2 d的母鼠随机分为:对照组和长期分离模型组,对照组不给予任何刺激,长期分离模型组母鼠给予每天3 h分离建立产后抑郁母鼠模型,10 d后,将造模成功的母鼠再分为:模型组、低浓度组和高浓度组,每组10只,加上对照组,共4组。模型组、低浓度组和高浓度组分别灌胃蒸馏水、15 mg/kg·d-1和30 mg/kg·d-1大豆异黄酮10 d,之后观察强迫游泳和悬尾实验中挣扎的时间、频次和静止的时间、频次,取血检测血清E 2和DA浓度,取脑免疫组化检测杏仁内侧核(MeA)、终纹床核(BNST)和中视前区(mPOA)ERβ的表达。结果:与对照组比较,模型组和低浓度组小鼠在强迫游泳和悬尾实验中的运动时间和频次明显降低,血清中的DA、ERβ浓度明显降低(P<0.05或P<0.01),模型组、低浓度和高浓度的E 2均明显降低(P<0.01);与模型组比较,低浓度组小鼠在强迫游泳和悬尾实验中运动时间、mPOA内ERβ表达显著升高(P<0.05),高浓度组小鼠在强迫游泳和悬尾实验中运动时间和频次、血清DA浓度和ERβ表达均明显升高(P<0.05或P<0.01);与低浓度组比较,高浓度组在强迫游泳和悬尾实验中运动时间和频次、血清DA浓度和ERβ表达均明显升高(P<0.05或P<0.01)。结论:大豆异黄酮可减少母鼠的抑郁样行为,尤其是较高浓度大豆异黄酮减少更为明显,而抑郁样行为的减少可能与大豆异黄酮使血清多巴胺和雌激素受体β水平升高有关。

目的探讨母婴分离对母亲焦虑样行为的影响以及与雌激素受体α(ERα)和β(ERβ)相关的机制。方法将30只C57BL/6 J母鼠分为对照组(CG,10只,不分离组)、短暂分离组(SG,10只,从分娩第2天~第10天母婴每天分离15 min)及长期分离组(LG,10只,从分娩第2天~第10天,母婴每天分离3 h)。通过旷场实验(OF)和高架十字实验(EPM)检测动物是否有焦虑样行为;通过免疫组织化学方法检测中脑区内侧视前区(m POA)、下丘脑腹内侧核(VMH)和杏仁内侧核(MeA)ERα和ERβ免疫反应神经元(ERα-IRs和ERβ-IRs)的变化。结果在OF中,LG组与CG组和SG组相比在旷场中心活动时间、穿格次数和总距离减少具有极显著性意义(P0.05)。在EPM中,LG组在开臂中活动时间占总时间百分比和运动距离极明显少于CG组和SG组(P<0.001),运动的总距离也比CG组和SG组明显减少(P<0.001)。免疫组织化学实验结果显示,LG组在m POA、VMH和MeA 3个区域中ERα-IRs和ERβ-IRs明显低于CG组和SG组(P<0.001)。结论母婴长期分离可能使母鼠产生焦虑样行为,而这一行为的产生可能与脑区ERα和ERβ显著减少有关。

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
