A novel environment-friendly system is proposed to fabricate polymer brush, which has the advantages including non-toxic and inexpensive initiator （eosin Y）, visible-light exposure （λ = 515 nm）, water medium and ambient environment. The experimental results from UV-Vis spectroscopy, AFM-based single molecule force spectroscopy （SMFS） and other measurements indicate that a polymer brush with a living nature is fabricated via free radical polymerization. This polymer brush may find applications in coatings, bio-interfaces and so forth.

目的比较不同低阶像差矫正方式对双通道视觉质量分析系统测量结果影响,并分析影响其测量的相关因素。方法在无其他眼病的67例单纯性屈光不正志愿者左右眼中随机选择一眼共67眼,分别使用传统框架眼镜矫正与双通道客观成像质量分析系统内置矫正方法进行光学成像质量和散射情况测量。比较两者MTF截止空间频率(MTF cutoff)、斯特列尔比值(strehl ratio,SR)、客观散射指数(objective scattering index,OSI)值差异,并分析造成两者测量差异原因。结果传统框架眼镜矫正法与OQAS仪器内置矫正法测得的MTFcutoff值分别为(39.83±9.11)c·deg-1、(40.34±10.02)c·deg-1(t=-0.59,P=0.56);SR值分别为(0.22±0.06)c·deg-1、(0.22±0.06)c·deg-1(t=-0.90,P=0.37);OSI值分别为(0.50±0.06)c·deg-1、(0.40±0.05)c·deg-1(t=-2.96,P=0.004);两种矫正方法的最佳聚焦点等效球镜差值为(0.02±0.39)D,等效球镜度数符合率(相差≤0.50D)为91%(61/67)。OSI差值与最佳聚焦点等效球镜差值存在负相关关系(r=-0.38,P<0.05)。MTFcutoff差值与最佳聚焦点等效球镜差值存在正相关关系(r=0.54,P<0.05)。结论双通道客观视觉质量分析系统内置的低阶像差矫正技术不影响光学质量评价,是一种临床上准确、可靠的视觉质量评估方法。

The infiltration of glioblastoma multiforme(GBM) is predominantly characterized by diffuse spread, contributing significantly to therapy resistance and recurrence of GBM. In this study, we reveal that microtubule deacetylation, mediated through the downregulation of fibronectin type III and SPRY domain-containing 1(FSD1), plays a pivotal role in promoting GBM diffuse infiltration. FSD1 directly interacts with histone deacetylase 6(HDAC6) at its second catalytic domain, thereby impeding its deacetylase activity on α-tubulin and preventing microtubule deacetylation and depolymerization. This inhibitory interaction is disrupted upon phosphorylation of FSD1 at its Ser317 and Ser324 residues by activated CDK5, leading to FSD1 dissociation from microtubules and facilitating HDAC6-mediated α-tubulin deacetylation. Furthermore, increased expression of FSD1 or interference with FSD1 phosphorylation reduces microtubule deacetylation, suppresses invasion of GBM stem cells, and ultimately mitigates tumor infiltration in orthotopic GBM xenografts. Importantly, GBM tissues exhibit diminished levels of FSD1 expression, correlating with microtubule deacetylation and unfavorable clinical outcomes in GBM patients. These findings elucidate the mechanistic involvement of microtubule deacetylation in driving GBM cell invasion and offer potential avenues for managing GBM infiltration.

Fast beam range measurements are required to maximize the time available for patient treatment, given that the beam range requires verification with respect to quality assurance to maintain accelerator commissioning standards and ensure patient safety. A novel beam range monitor based on a plastic scintillator and multi-pixel photon counter (MPPC) arrays is therefore proposed in this paper. The monitor was constructed using 128 plastic scintillator films with a thickness of 1 mm and an active area of 50 × 50 mm^(2). A customized MPPC array read the scintillation light of each film. The advantage of dividing the active detector volume into films is that it intercepts the particle beam and enables direct differential light yield measurement in each film, in addition to depth-light curve generation without the need for image analysis A GEANT4 simulation, including scintillator quenching effects, was implemented, and the results revealed that Birks’ law exhibited a slight little influence on the position of the beam range, only changing the shape and absolute normalization of the Bragg curve, which is appropriate for the calculation of the beam range using the depth-light curve. The performance of the monitor was evaluated using a heavy-ion medical machine in Wuwei City, Gansu Province, China. The beam range measurement accuracy of the monitor was 1 mm, and the maximum difference between the measured and reference ranges was less than0.2%, thus indicating that the monitor can meet clinica carbon ion therapy requirements.

人眼眩光一般是指由于从外界进入眼内的迷乱光线抑制了正常光线在视网膜上的成像而形成的不舒适感觉。其在不同的领域及专业中涵义均有所不同。尽管目前眩光测量方法众多，但尚无统一的评价标准。在临床及研究工作中需谨慎甄别不同眩光定义及测量方法对患者视觉质量评估造成的偏倚。由于眩光研究受到其复杂的发生机制和缺乏跨学科交流的影响，目前尚无一种方法能全面有效地防治眩光。本文通过回顾分析眩光在眼科、照明工程、神经学以及其他相关学科的出版物及研究报道，对临床上常见的眩光类型如失能眩光、幻影眩光、不舒适眩光和畏光的发生机制、测量手段和解决方法的研究现状进行综述。

Self-supervised graph representation learning has recently shown considerable promise in a range of fields, including bioinformatics and social networks. A large number of graph contrastive learning approaches have shown promising performance for representation learning on graphs, which train models by maximizing agreement between original graphs and their augmented views(i.e., positive views). Unfortunately, these methods usually involve pre-defined augmentation strategies based on the knowledge of human experts. Moreover, these strategies may fail to generate challenging positive views to provide sufficient supervision signals. In this paper, we present a novel approach named graph pooling contrast(GPS) to address these *** by the fact that graph pooling can adaptively coarsen the graph with the removal of redundancy, we rethink graph pooling and leverage it to automatically generate multi-scale positive views with varying emphasis on providing challenging positives and preserving semantics, i.e., strongly-augmented view and weakly-augmented view. Then, we incorporate both views into a joint contrastive learning framework with similarity learning and consistency learning, where our pooling module is adversarially trained with respect to the encoder for adversarial robustness. Experiments on twelve datasets on both graph classification and transfer learning tasks verify the superiority of the proposed method over its counterparts.

Enhancing thermal conductivity coefficient (λ) of liquid crystal polyesters would further widen their application in electronics and electricals. In this work, a kind of biphenyl-based dihydroxy monomer is synthesized using 4, 4’-biphenyl (BP) and triethylene glycol (TEG) as raw material, which further reacts with three different dicarboxylic acids (succinic acid, p-phenylenediacetic acid, and terephthalic acid, respectively) by melt polycondensation to prepare intrinsically highly thermally conductive poly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p-hydroxybiphenyl) succinate (PEOS), poly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p-hydroxybiphenyl) p-phenyldiacetate (PEOP) and poly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p-hydroxybiphenyl) terephthalate (PEOT), collectively called biphenyl-based liquid crystal polyesters (B-LCPE). The results show that B-LCPE possess the desired molecular structure, exhibit smectic phase in liquid crystal range and semicrystalline polymers at room temperature, and possess excellent intrinsic thermal conductivities, thermal stabilities, and mechanical properties. λ of PEOT is 0.51 W/(m·K), significantly exceeds that of polyethylene terephthalate (0.15 W/(m·K)) which has similar molecular structure with PEOT, and also higher than that of PEOS (0.32 W/(m·K)) and PEOP (0.38 W/(m·K)). The corresponding heat resistance index (THRI), elasticity modulus, and hardness of PEOT are 174.6℃, 3.6 GPa, and 154.5 MPa, respectively, and also higher than those of PEOS (162.2℃, 1.8 GPa, and 83.4 MPa) and PEOP (171.8℃, 2.3 GPa, and 149.6 MPa).
