Crystalline and nanostructured cobalt （CoFe2O4）, nickel （NiFe2O4）, zinc （ZnFe2O4） and manganese （MnFe2O4） spinel ferrites are synthesized with high yields, crystallinity and purity through an easy, quick, reproducible and low-temperature hydrothermal assisted route starting from an aqueous suspension of copredpitated metal oxalates. The use of water as a reaction medium is a further advantage of the chosen protocol. Additionally, the zinc spinel is also prepared through an alternative route combining copredpitation of oxalates from an aqueous solution with thermal decomposition under reflux conditions. The nanocrystalline powders are obtained as a pure crystalline phase already at the extremely low tem- perature of 75 ℃ and no further thermal treatment is needed. The structure and microstructure of the prepared materials is investigated by means of X-ray powder diffraction （XRPD）, while X-ray photoelectron spectroscopy （XPS） and inductively coupled plasma-atomic emission spectroscopy （ICP-AES） analyses are used to gain information about the surface and bulk composition of the samples, respectively, confirming the expected stoichiometry. To investigate the effect of the synthesis protocol on the morphology of the obtained ferrites, transmission electron microscopy （TEM） observations are performed on selected samples. The magnetic properties of the cobalt and manganese spinels are also investigated using a superconducting quantum device magnetometer （SQUID） revealing hard and soft ferrimagnetic behavior, respectively.

The Quantum Lattice Boltzmann Equation:Recent Developments

Communications in Computational Physics 2008年第10期4卷 980-1007页

作者： silvia Palpacelli Sauro Succi Dipartimento di Matematica Universit`a Roma TreLargo San Leonardo Murialdo 100146RomaItaly Istituto Applicazioni del Calcolo Viale Policlinico 13700161 RomaItaly

The derivation of the quantum lattice Boltzmann model is reviewed with special emphasis on recent developments of the model,namely,the extension to a multi-dimensional formulation and the application to the computation of the ground state of the gross-Pitaevskii equation(GPE).Numerical results for the linear and nonlinear Schr odinger equation and for the ground state solution of the GPE are also presented and validated against analytical results or other classical schemes such as Crank-Nicholson.

Background/Aim: To assess safety of hypo-fractionated radiotherapy( HyRT) followed by low dose radiation therapy( LD-FRT) plus Temozolomide( TMZ) in naive unresectable Glioblastoma. Methods: Patients( ECOG 18) undergone to biopsy or with gross residual tumor after surgery were enrolled. HyRT( 30 Gy in ten fraction) plus TMZ was administered. From the second adjuvant cycle of TMZ,patients received LD-FRT( 0. 40 Gy twice daily over 5 days,every 28 days) for two cycles. The primary endpoints were safety and toxicity. Moreover we analyzed response,overall survival( OS) and progression-free survival( PFS). Results: Twenty patients were enrolled. Median dose of LD-FRT was 12 Gy. All toxicities were reversible. Four out of 20 patients had Partial Response( PR)and 6 experienced a stable disease( SD). Median OS and PFS were 14 and 11 months,***: HyRT followed by LD-FRT plus TMZ is safe and shows good clinical outcomes. A new study is ongoing.

小胶质细胞是调节大脑突触发育和可塑性的重要细胞类型,但其影响突触的正常功能的机制尚不清楚。在本研究中,我们通过PLX5622造成小胶质细胞耗竭,并观察其对成年野生型小鼠海马CA3-CA1突触的影响。在小胶质细胞耗竭后,与树突棘密度降低相关的自发和诱发谷氨酸能活动的减少,出现未成熟突触特征以及突触的可塑性提高。小胶质细胞耗竭的小鼠在新物体识别任务的获取方面表现出缺陷。海马星形胶质细胞出现增生,但并没有神经炎症反应。在Cx3cr1-/-小鼠中,PLX不能导致海马出现上述改变。这说明CX3CL1/CX3CR1轴在小胶质细胞对突触功能的控制中有重要作用。PLX5622停用后,小胶质细胞的重新增殖,海马突触恢复,小鼠的学习功能也出现恢复。综上所述,小胶质细胞对维持成人大脑的突触的正常功能用重要的作用,去除小胶质细胞会导致谷氨酸能突触组织和活动的可逆变化。
