  A European Perspective on Depression in the Community: The DEPRES Study

  摘要：

  摘要抑郁症是普通人群中最常见的疾病之一，会造成个人和社会的残疾和损伤。对抑郁症的诊断和管理进行评估的主要研究表明，抑郁症往往诊断不足、治疗不力。本文报告了一项泛欧研究，旨在评估六个不同国家抑郁症的程度和后果。研究分析了不同类型的抑郁症，并对其各自的治疗方法进行了比较。文章强调了改进抑郁症诊断和治疗的重要性。抑郁症的适当治疗取决于患者对抑郁症状的认识、他们寻求治疗的可能性以及初级保健医生识别疾病和开具适当药物的能力。所有这些领域都需要改进。

• Phase and Microstructural Development of Sol-gel-derived Strontium Barium Niobate Thin Films

  日期：2000.6

  Microstructural changes in sol-gel-derived Sr_xBa_1−xNb₂O₆ (SBN) thin films were monitored as a function of Ba-to-Sr ratio (from x = 0 to x = 1), choice of substrate (Si or MgO), and processing variations. Sols were created using Ba, Sr, and Nb alkoxides dissolved in acetic acid. The relatively high decomposition temperature for the organics led to a tendency to form defects, but careful control of thermal process parameters could be used to produce a uniform film microstructure. An unexpected phase, interpreted as a hexagonal (pseudo-orthorhombic) variant of hexagonal BaNb₂O₆, was encountered in Ba-rich sol-gel-derived SBN powders and thin films annealed at 750 °C. Increased (001) orientation was observed for SBN thin films deposited on (100) MgO when fast thermal processing was used.

• The β Effect of Silicon in Phenyl Cations

  Irradiation of chloroanisoles, phenols, and N,N-dimethylanilines bearing a trimethylsilyl (TMS) group in the ortho position with respect to the chlorine atom caused photoheterolysis of the Ar-Cl bond and formation of the corresponding ortho-trimethylsilylphenyl cations in the triplet state. The beta effect of silicon on these intermediates has been studied by comparing the resulting chemistry in alcoholic solvents with that of the silicon-free analogues and by computational analysis (at the UB3LYP/6-311+G(2d,p) level in MeOH). TMS groups little affect the photophysics and the photocleavage of the starting phenyl chlorides, while stabilizing the phenyl cations, both in the triplet (ca. 4 kcal/mol per group) and, dramatically, in the singlet state (9 kcal/mol). As a result, although triplet phenyl cations are the first formed species, intersystem crossing to the more stable singlets is favored with chloroanisoles and phenols. Indeed, with these compounds, solvent addition to give aryl ethers (from the singlet) competed efficiently with reduction or arylation (from the triplet). In the case of the silylated 4-chloro-NN-dimethylaniline, the triplet cation remained in the ground state and trapping by pi nucleophiles remained efficient, though slowed by the steric bulk of the TMS group. In alcohols, the silyl group was eliminated via a photoinduced protiodesilylation during the irradiation. Thus, the silyl group could be considered as a directing, photoremovable group that allowed shifting to the singlet phenyl cation chemistry and was smoothly eliminated in the same one-pot procedure.
