Diário da Constituinte [gravação de vídeo] : [programa n. 120]

Representantes da Associação dos Delegados de Polícia (ADEPOL), reuniram-se com o Deputado João Natal (PMDB-GO) e apresentaram sugestões para a melhoria das condições de trabalho da classe. Na sessão O Povo Pergunta, cidadã indaga se a divisão dos Estados acarretará maior disponibilidade de verbas. Nabor Júnior (PMDB-AC) responde que é favorável, dentro das possibilidades econômicas do país, a redivisão territorial dos Estados e que o argumento de falta de recursos da União para custear a implantação desses novos Estados não tem consistência. Os deputados da Assembleia Legislativa da Bahia entregaram a Marcelo Cordeiro (PMDB-BA), 1º Secretário da Assembleia Nacional Constituinte (ANC), documento pedindo a preservação da unidade do território baiano. Coriolano Salles, Presidente da Assembleia, relata que o povo baiano deseja que a Bahia se mantenha íntegra, indivisível. Jorge Hage (PMDB-BA) afirma que não há razão para enfraquecer um Estado com as dimensões, perspectivas e potencial como o da Bahia e acredita que a Assembleia Nacional Constituinte não aprovará a divisão. Na questão da reforma tributária, os municipalistas começaram a agir junto a Comissão de Sistematização, no sentido de garantir os direitos dos municípios. Os Deputados Vivaldo Barbosa (PDT-RJ), Hélio Manhães (PMDB-ES) e Maguito Vilela (PMDB-GO), da bancada municipalista apoiam a descentralização da receita nacional.

Compact 120 TW Ti: sapphire laser system with a high gain final amplifier

A 120TW/36fs laser system based on Ti:sapphire chirped-pulse amplification (CPA) has been successfully established in our lab. The final four pass Ti:sapphire amplifier pumped by an energetic single-shot Nd:YAG-Nd:glass laser was designed and optimized. With 24J/8ns pump energy at 532 nm, 300 mJ/220 ps chirped pulse was amplified to 5.98 J in this amplifier, and a total saturated gain of similar to 20 was achieved. The focused intensity of compressed beam could reach to 10(20) W/cm(2) with the M-2 of similar to 2.0. (c) 2005 Elsevier Ltd. All rights reserved.

Comment on "Acoustic chaos in a duct with two separate sound sources" [J. Acoust. Soc. Am. 110, 120-126 (2001)] (L)

In a paper published in this journal in 2001 by Dong [W. G. Dong, X. Y. Huang, and Q. L. Wo, J. Acoust. Soc. Am. 110, 120-126 (2001)] it was claimed that acoustic chaos was obtained experimentally by the nonlinear interaction of two acoustic waves in a duct. In this comment a simple experimental setup and an analytical model is used to show that the dynamics of such systems corresponds to a quasiperiodic motion, and not to a chaotic one. © 2008 Acoustical Society of America.

天然产物及相关复方配伍的质谱及液相色谱研究

质谱技术以其灵敏度高、样品需求量少、快速准确的特点在生物大分子体系和天然产物的化学成分研究中起着极为重要的作用。特别是软电离质谱技术的发展，大大简化了化合物的测定过程，提高了分析研究速度，为分析植物及食物中的结构信息提供了快速便捷的方法。HPLC-ESI-MSn是90年代发展成熟的分析技术，它集液相色谱的高分离能力与质谱的高灵敏度和高专属性于一体，已成为包括药物微量杂质、药物降解产物、药代代谢动力学研究、组合化学合成产物高通量分析以及天然产物的化学筛选在内的现代药学研究领域最强有力的分析工具之一。本文首先采用电喷雾多级串联质谱技术，系统地研究了负离子条件下黄酮普元、黄酮醇普元以及二氢黄酮普元等化合物的特征质谱行为，并对中药黄芬中三种黄酮昔化合物进行了研究。利用这些特征碎片离子，可以简便快捷的区分结构类似的黄酮类化合物及其同分异构体。通过对黄酮C一昔类化合物的电喷雾串联质谱（ESI-MSn）研究，提出黄酮C-苷类化合物的特征碎裂规律，证明〔M-H-60］-，〔M-H-90］-，〔M-H-120〕-为黄酮C-苷类化合物的特征离子。为鉴定植物粗提物中黄酮类化合物奠定了基础。之后我们进一步采用高效液相色谱与电喷雾质谱联用技术，在线区分混合物中的黄酮类化合物的同分异构体。根据黄酮类化合物的电喷雾质谱规律以及化合物的色谱保留时间分析鉴定了黄答中的七种黄酮类化合物。建立了一种有效检测黄芩（Scutellariabaicalensis Georgi）中黄酮类化合物的快速灵敏的分析方法，为建立黄答药材的质量控制标准提供了借鉴。对于黄酮类化合物灵敏、快速和准确的分析方法的建立，不仅为黄酮类化合物的结构的快速鉴定提供了一定的依据，而且对生药的鉴别和制剂的质控起到重要的作用。利用电喷雾多级串联质谱技术，对化学结构相似的黄酮营、二氢黄酮营和黄酮醇昔类化合物进行了对比研究。并且首次利用高分辨质谱FTICR-MS及SORI-CID技术对naringin进行了质谱研究。利用其超高分辩率、准确质量确证了中性碎片丢失，进一步证明了我们对其碎裂机理的推断。之后，我们通过金属离子与黄酮昔溶液混合后，采用电喷雾串联质潜法进行测定。实验表明通过人为加入某些金属离子如Li+，Na+和K+，特别是Li＋可以提高黄酮昔类化合物分析灵敏度，从而提供较多结构信息。并且在串联质谱中表现不同的碎裂行为，为黄酮类化合物结构分析提供补充信息。研究表明结合〔M-H］-，〔M＋Na〕+，〔M＋Li〕+离子串联质潜提供的信息，能够有效的鉴定黄酮普的结构。本文通过电喷雾串联质谱（ESI-MSn）和液质联机技术（HPLC-ESI-MS／MS）研究了原小聚碱型生物碱。首次利用高分辨质谱FTICR-MS和SORI-CTD技术对原小桨碱型生物碱进行了高分辨质谱研究，提出了各种碎片离子的碎裂途径，并总结了原小聚碱型生物碱的质谱碎裂规律，为鉴定此类型的生物碱提供了依据。之后通过电喷雾串联质谱研究了四种生物碱化合物质谱行为。最后我们利用液质联机技术（HPLC-ESI-MSn），通过与标准品的液相保留时间对照及原小聚碱型生物碱的质谱碎裂规律，建立了分析鉴定常用中药中原小聚碱型生物碱的快捷方法。并通过选择离子监控技术（SIM）提高了对于同分异构体的分离鉴定。通过色谱UV吸收峰定量研究了这四种药用植物中小璧碱和巴马汀的含量，为临床应用提供一定的化学基础，为建立中药质量控制标准及植物分类学提供一定的依据。采用HPLC法考察了常见的黄连药对组合煎煮对黄连中小聚碱、巴马丁煎出量的影响。为制药工艺的优化奠定了基础。之后我们以中药理论为指导，按药物性味对改良半夏泻心汤中各药进行分组，利用高效液相色谱分析了不同配伍条件下小璧碱、巴马丁煎出量的变化。为组方的合理性和科学性提供了一定的化学物质基础依据。

Reconstruction of vertical thermal structure from several subsurface temperatures in the China Seas and adjacent waters

Empirical Orthogonal Function (EOF) analysis is used in this study to generate main eigenvector fields of historical temperature for the China Seas (here referring to Chinese marine territories) and adjacent waters from 1930 to 2002 (510 143 profiles). A good temperature profile is reconstructed based on several subsurface in situ temperature observations and the thermocline was estimated using the model. The results show that: 1) For the study area, the former four principal components can explain 95% of the overall variance, and the vertical distribution of temperature is most stable using the in situ temperature observations near the surface. 2) The model verifications based on the observed CTD data from the East China Sea (ECS), South China Sea (SCS) and the areas around Taiwan Island show that the reconstructed profiles have high correlation with the observed ones with the confidence level > 95%, especially to describe the characteristics of the thermocline well. The average errors between the reconstructed and observed profiles in these three areas are 0.69A degrees C, 0.52A degrees C and 1.18A degrees C respectively. It also shows the model RMS error is less than or close to the climatological error. The statistical model can be used to well estimate the temperature profile vertical structure. 3) Comparing the thermocline characteristics between the reconstructed and observed profiles, the results in the ECS show that the average absolute errors are 1.5m, 1.4 m and 0.17A degrees C/m, and the average relative errors are 24.7%, 8.9% and 22.6% for the upper, lower thermocline boundaries and the gradient, respectively. Although the relative errors are obvious, the absolute error is small. In the SCS, the average absolute errors are 4.1 m, 27.7 m and 0.007A degrees C/m, and the average relative errors are 16.1%, 16.8% and 9.5% for the upper, lower thermocline boundaries and the gradient, respectively. The average relative errors are all < 20%. Although the average absolute error of the lower thermocline boundary is considerable, but contrast to the spatial scale of average depth of the lower thermocline boundary (165 m), the average relative error is small (16.8%). Therefore the model can be used to well estimate the thermocline.

Characteristics of water exchange in the Luzon Strait during September 2006

The Luzon Strait is the only deep channel that connects the South China Sea (SCS) with the Pacific. The transport through the Luzon Strait is an important process influencing the circulation, heat and water budgets of the SCS. Early observations have suggested that water enters the SCS in winter but water inflow or outflow in summer is quite controversial. On the basis of hydrographic measurements from CTD along 120 degrees E in the Luzon Strait during the period from September 18 to 20 in 2006, the characteristics of temperature, salinity and density distributions are analyzed. The velocity and volume transport through the Luzon Strait are calculated using the method of dynamic calculation. The major observed results show that water exchanges are mainly from the Pacific to the South China Sea in the upper layer, and the flow is relatively weak and eastward in the deeper layer. The net volume transport of the Luzon Strait during the observation period is westward, amounts to about 3.25 Sv. This result is consistent with historical observations.

Ozonation of the purified hydrolyzed azo dye Reactive Red 120 (CI)

The combination of chemical and biological water treatment processes is a promising technique to reduce recalcitrant wastewater loads. The key to the efficiency of such a system is a better understanding of the mechanisms involved during the degradation processes. Ozonation has been applied to many fields in water and wastewater treatment. Especially for effluents of textile finishing industry ozonation can achieve high color removal, enhance biodegradability, destroy phenols and reduce the COD. However, little is known about the reaction intermediates and products formed during ozonation. This work focuses on the oxidative degradation of purified (>90%), hydrolyzed Reactive Red 120 (Color Index), a widely used azo dye in the textile finishing processes with two monochlorotriazine anchor groups. Ozonation of the dye in ultra pure water was performed in a laboratory scale cylindrical batch reactor. Decolorization, determined by measuring the light absorbance at the maximum wavelength in the visible range (53 5 nm), was almost complete after 150 min with an ozone concentration of 12.8 mg/l. The TOC/TOC0 ratio was about 74% and the COD was diminished to 46% of the initial value. The BOD5/COD ratio increased from 0.01 to 0.14. To obtain detailed information on the reaction processes during ozonation and the resulting oxidation products organic and inorganic anions were analyzed. Oxidation and cleavage of the azo group yielded nitrate. Cleavage of the sulfonic acid groups of aromatic rings caused an increase in the amount of sulfate. Formic acid and oxalic acid were identified as main oxidation products by high performance ion chromatography (HPIC). The concentrations of these major products were monitored at defined time intervals during ozonation.

Yeast screens identify the RNA polymerase II CTD and SPT5 as relevant targets of BRCA1 interaction.

BRCA1 has been implicated in numerous DNA repair pathways that maintain genome integrity, however the function responsible for its tumor suppressor activity in breast cancer remains obscure. To identify the most highly conserved of the many BRCA1 functions, we screened the evolutionarily distant eukaryote Saccharomyces cerevisiae for mutants that suppressed the G1 checkpoint arrest and lethality induced following heterologous BRCA1 expression. A genome-wide screen in the diploid deletion collection combined with a screen of ionizing radiation sensitive gene deletions identified mutants that permit growth in the presence of BRCA1. These genes delineate a metabolic mRNA pathway that temporally links transcription elongation (SPT4, SPT5, CTK1, DEF1) to nucleopore-mediated mRNA export (ASM4, MLP1, MLP2, NUP2, NUP53, NUP120, NUP133, NUP170, NUP188, POM34) and cytoplasmic mRNA decay at P-bodies (CCR4, DHH1). Strikingly, BRCA1 interacted with the phosphorylated RNA polymerase II (RNAPII) carboxy terminal domain (P-CTD), phosphorylated in the pattern specified by the CTDK-I kinase, to induce DEF1-dependent cleavage and accumulation of a RNAPII fragment containing the P-CTD. Significantly, breast cancer associated BRCT domain defects in BRCA1 that suppressed P-CTD cleavage and lethality in yeast also suppressed the physical interaction of BRCA1 with human SPT5 in breast epithelial cells, thus confirming SPT5 as a relevant target of BRCA1 interaction. Furthermore, enhanced P-CTD cleavage was observed in both yeast and human breast cells following UV-irradiation indicating a conserved eukaryotic damage response. Moreover, P-CTD cleavage in breast epithelial cells was BRCA1-dependent since damage-induced P-CTD cleavage was only observed in the mutant BRCA1 cell line HCC1937 following ectopic expression of wild type BRCA1. Finally, BRCA1, SPT5 and hyperphosphorylated RPB1 form a complex that was rapidly degraded following MMS treatment in wild type but not BRCA1 mutant breast cells. These results extend the mechanistic links between BRCA1 and transcriptional consequences in response to DNA damage and suggest an important role for RNAPII P-CTD cleavage in BRCA1-mediated cancer suppression.
