Evaluation of chromosomal abnormalities by cIg-FISH and association with proliferative and apoptotic indexes in multiple myeloma

Eighty-six newly diagnosed multiple myeloma (MM) patients from a public hospital of São Paulo (Brazil) were evaluated by cIg-FISH for the presence of del(13)(q14), t(4;14)(p16.3;q32) and del(17)(p13). These abnormalities were observed in 46.5, 9.3, and 7.0% of the patients, respectively. In order to identify the possible role of del(13)(q14) in the physiopathology of MM, we investigated the association between this abnormality and the proliferative and apoptotic indexes of plasma cells. When cases demonstrating t(4;14)(p16.3;q32) and del(17)(p13) were excluded from the analysis, we observed a trend towards a positive correlation between the proportion of cells carrying del(13)(q14) and plasma cell proliferation, determined by Ki-67 expression (r = 0.23, P = 0.06). On the other hand, no correlation between the proportion of cells carrying del(13)(q14) and apoptosis, determined by annexin-V staining, was detected (r = 0.05, P = 0.69). In general, patients carrying del(13)(q14) did not have lower survival than patients without del(13)(q14) (P = 0.15), but patients with more than 80% of cells carrying del(13)(q14) showed a lower overall survival (P = 0.033). These results suggest that, when del(13)(q14) is observed in a high proportion of malignant cells, it may have a role in determining MM prognosis. Another finding was a statistically significant lower overall survival of patients with t(4;14)(p16.3;q32) (P = 0.026). In the present study, almost half the patients with t(4;14)(p16.3;q32) died just after diagnosis, before starting treatment. This fact suggests that, in São Paulo, there may be even more patients with this chromosomal abnormality, but they probably die before being diagnosed due to unfavorable socioeconomic conditions. This could explain the low prevalence of this chromosomal abnormality observed in the present study.

Dashboards in performance management: The foundations and research opportunities for their effective use

When designed effectively dashboards are expected to reduce information overload and improve performance management. Hence, interest in dashboards has increased recently,which is also evident from the proliferation of dashboard solution providers in the market. Despite dashboards popularity, little is known about the extent of their effectiveness in organizations. Dashboards draw from multiple disciplines but ultimately use visualization to communicate important information to stakeholders. Thus,a better understanding of visualization can improve the design and use of dashboards. This paper reviews the foundations and roles of dashboards in performance management and proposes a framework for future research, which can enhance dashboard design and perceived usefulness depending on the fit between the features of the dashboard and the characteristics of the users.

Quantum stochastic calculus associated with quadratic quantum noises

We first study a class of fundamental quantum stochastic processes induced by the generators of a six dimensional non-solvable Lie dagger-algebra consisting of all linear combinations of the generalized Gross Laplacian and its adjoint, annihilation operator, creation operator, conservation, and time, and then we study the quantum stochastic integrals associated with the class of fundamental quantum stochastic processes, and the quantum Ito formula is revisited. The existence and uniqueness of solution of a quantum stochastic differential equation is proved. The unitarity conditions of solutions of quantum stochastic differential equations associated with the fundamental processes are examined. The quantum stochastic calculus extends the Hudson-Parthasarathy quantum stochastic calculus. (C) 2016 AIP Publishing LLC.

Computational information geometry and its applications

Digitization is the main feature of modern Information Science. Conjoining the digits and the coordinates, the relation between Information Science and high-dimensional space is consanguineous, and the information issues are transformed to the geometry problems in some high-dimensional spaces. From this basic idea, we propose Computational Information Geometry (CIG) to make information analysis and processing. Two kinds of applications of CIG are given, which are blurred image restoration and pattern recognition. Experimental results are satisfying. And in this paper, how to combine with groups of simple operators in some 2D planes to implement the geometrical computations in high-dimensional space is also introduced. Lots of the algorithms have been realized using software.

由二酐的异构体合成的聚酰亚胺

聚酰亚胺是一类综合性能优异的重要耐热高分子材料，它在航空，航天工业，微电子工业等诸多领域获得了广泛的应用。异构的聚酰亚胺是近几年新兴起的结构材料之一，与传统结构的聚酰亚胺比较，具有更高的玻璃化温度，良好的溶解性能，低的熔融粘度，宽的加工窗口，和相当的机械性能和热稳定性，是一种较有发展前景的结构材料；同时异构的二酐单体又可以用来合成芳香环状聚酰亚胺，对这些十分稳定又具有很好溶解性能的环状齐聚体的研究还刚刚开始。为此，本论文主要就以下方面开展研究工作：1，以环己烯为原料，经六步，高收率地合成了PMDA的异构体，MPDA。发现MPDA在室温下同甲醇和苯胺的开环选择反应分别得到了不对称的酷化产物和对称的酞化产物，这种开环选择的差别可归结于在酞化反应过程中形成了环状氢键中间体。通过MPDA和苯胺的亚胺化反应研究，发现在DMAc中热环化得到单亚胺化合物和双亚胺化合物的混合物，而在对氯酚中热环化或者在DMAc中化学环化均只得到唯一双亚胺化合物。单晶X-Ray衍射证实了单亚胺化合物的结构。发现在DMAc中热环化时单亚胺化合物和双亚胺化合物可以相互转化，而在氮气或者真空高温条件下单亚胺化合物不能转化成双亚胺化合物，从而提出了反应机制，即少量DMAc中的水分可以影响生成单亚胺化合物。发现MPDA和ODA或者MDA聚合时有很大的生成环状聚酰亚胺的倾向，它们的环状性质由IR，MALDI-TOF-MS，和NMR所证实。发现环状聚酰胺酸放置时，不同的环之间可以发生转换，从而可以提高受热力学控制的环的收率。用溶剂萃取和重结晶的方法分离得到了环状聚酰亚胺二聚体，用单晶X-Ray衍射的方法表征了二聚体包容不同溶剂时的分子结构，从分子水平的角度研究了环状聚酞亚胺的结构和性能的关系。除了MPDA得到的聚酞亚胺有较高的g值外，异构体聚酰亚胺的其它性能如力学性能、热稳定性能、溶解度性能、形态结构性能等差别不大。2．以2，3-二甲基苯胺为原料，经四步，高收率地得到了3,3'-BTDA。发现螺双内酚在乙酸配中回流可以直接有效地转化成二配3,3'-BTDA，并提出了转化机制。单晶X-Ray衍射表明3,3'-BTDA和3,4'-BTDA都有非共平面的分子结构。通过研究异构的BTDA得到的聚酞亚胺，发现并表征了3,3'-BTDA和ODA聚合时有很大的生成环状聚酞亚胺的倾向。异构化BTDA得到的聚酞亚胺的Tg值规律：3,3'-BTDA＞3,4'-BTDA＞4,4'-BTDA；溶解性能规律：3,3'-BTDA＞3,4'-BTDA＞4,4'-BTDAA；融体粘度规律：3,3'-BTDA＞4,4'-BTDAA3,4'-BTDA；热机械性能规律：4,4'-BTDA澎3,4'-BTDA＞3,3'-BTDA。可以看出3,4'-BTDAA得到的聚酰亚胺既有良好的加工性能，又能保持材料的热机械性能。由DSC测得的异构模型化合物的Tm，△Hm，和△Sm数据可以有效地解释异构聚酰亚胺的Tg规律。3．合成了cis-1,2,3,4-CHDA，发现在一定条件下可以转化成它的异构体trans-1,2,3,4-CHDA，1HNMR直接跟踪热异构化反应的进程，并提出了转化机制。单晶X-Ray衍射确定了两个二配异构体的绝对构型。发现在用trans-1,2,3,4-CHDA制备聚酞亚胺时无论用两步法或者一步法，均能很容易地得到高分子量的聚合物。而它的异构体cig-1,2,3,4-CHDA在制备聚酞亚胺时，由于形成环状聚酞亚胺，用传统的方法得不到高分子量的聚合物，增加单体的浓度可以有效制得高分子量的聚合物。发现顺式聚合物的溶解性能比反式异构体的好，Tg值比相应反式异构体的高，其它如热氧化稳定性，机械性能，光学性能，异构体间没有明显的差别。但是，两个异构体都可以制得坚韧的透明薄膜。

Indicadores de sostenibilidad ambiental en el periurbano de la ciudad de Mar del Plata, Argentina

Los indicadores de sostenibilidad conforman herramientas útiles para la toma de decisiones. Las ciudades latinoamericanas, y especialmente las áreas de expansión sin planificación adecuada, enfrentan desafíos cada vez mayores para revertir problemáticas que amenazan su sostenibilidad. El presente trabajo evalúa de manera preliminar, la sostenibilidad ambiental del periurbano de Mar del Plata (Argentina) tomando como referencia algunos de los indicadores propuestos por el modelo del Banco Interamericano de Desarrollo en la Iniciativa Ciudades Emergentes y Sostenibles. Se construyó un índice sintético (Índice de Sostenibilidad Ambiental, ISA) que integra trece indicadores agrupados en ocho temas. Las situaciones más críticas (ISA: 0,45-0,558) se identifican fundamentalmente en zonas en las que se desarrollan actividades rurales y en las que se localizan asentamientos de carácter precario. El estudio realizado profundiza en el conocimiento de la dimensión ambiental de la sostenibilidad, enfatizando en el análisis de los contrastes internos del periurbano marplatense.

E-Cigarettes: A Review of New Trends in Cannabis Use.

The emergence of electronic cigarettes (e-cigs) has given cannabis smokers a new method of inhaling cannabinoids. E-cigs differ from traditional marijuana cigarettes in several respects. First, it is assumed that vaporizing cannabinoids at lower temperatures is safer because it produces smaller amounts of toxic substances than the hot combustion of a marijuana cigarette. Recreational cannabis users can discretely "vape" deodorized cannabis extracts with minimal annoyance to the people around them and less chance of detection. There are nevertheless several drawbacks worth mentioning: although manufacturing commercial (or homemade) cannabinoid-enriched electronic liquids (e-liquids) requires lengthy, complex processing, some are readily on the Internet despite their lack of quality control, expiry date, and conditions of preservation and, above all, any toxicological and clinical assessment. Besides these safety problems, the regulatory situation surrounding e-liquids is often unclear. More simply ground cannabis flowering heads or concentrated, oily THC extracts (such as butane honey oil or BHO) can be vaped in specially designed, pen-sized marijuana vaporizers. Analysis of a commercial e-liquid rich in cannabidiol showed that it contained a smaller dose of active ingredient than advertised; testing our laboratory-made, purified BHO, however, confirmed that it could be vaped in an e-cig to deliver a psychoactive dose of THC. The health consequences specific to vaping these cannabis preparations remain largely unknown and speculative due to the absence of comprehensive, robust scientific studies. The most significant health concerns involve the vaping of cannabinoids by children and teenagers. E-cigs could provide an alternative gateway to cannabis use for young people. Furthermore, vaping cannabinoids could lead to environmental and passive contamination.

Analisis de la politica exterior de Francia y Alemania frente a la Constitucion Europea de 2004, Bajo la Logica de la Nueva Razon de Estado

El Tratado que establece una Constitución para Europa (CNE) de 2004 fue el resultado de una serie de debates que iniciaron en el seno del eje franco-alemán, y se fueron expandiendo a los otros Estados miembro y Estados candidatos de Europa Central y Oriental (PECO¿s) de la UE. A través de la Convención Europea (CVE) se creó un borrador del tratado constitucional y posteriormente, en la CIG se negoció y firmó por los Jefes de Estado y de Gobierno de dichos Estados. La presente monografía pretende explicar y analizar las diferentes posturas que tuvieron Francia y Alemania, respecto al debate, la negociación, y la ratificación de la CNE.
