The paper describes the experiments conducted to create shape controllable preparations of submicronic cad- mium tetrazole-based MOFs. In order to prepare the submicron sized blocks and tubes of bis[5-（2-pyridyltetrazo- lato）]diaquacadmium（II） [（2-PTZ）2Cd（H20）2] MOFs both solvothermal and microwave augmented reaction proce- dures have been followed. Cadmium nitrate tetrahydrate, cyanopyridine and sodium azide were used as reactants in both the conditions without any surfactants or modulators. Subsequently, IR spectroscopy and single-crystal X-ray crystallographic studies were performed on the prepared MOFs. Examinations using scanning electron microscopy and X-ray powder diffraction of the products made by the microwave method showed formation of bundles of reg- ular submicrotubes, as opposed to the submicron-sized irregular blocks of the Cd-MOF obtained through the sol- vothermal method. The fluorescence peak of the sub-microtube MOF was found at 460 nm while the irregu- lar-blocks emitted at 442 nm indicating a red shift for the former. In addition, the relative intensity of the peak at 460 nm was higher in the former, indicating a decrease in the crystallite size. Band gaps of the MOFs calculated by using the Tauc plots were 2.87 and 2.73 eV, respectively. Their photocatalytic performances using methylene blue under UV-vis irradiation have been investigated.

In the present work, dense perovskite ceramics were successfully prepared from a series of La1-xBaxCoO3 solid solutions in the range of substitution 0 ≤ x ≤ 0.75 using solid state reaction and conventional sintering. Structural properties of La1-xBaxCoO3 were systematically investigated and thermoelectric properties were measured in the temperature range of 330–1000 K. The results show that the thermoelectric properties of Ba-substituted LaCoO3 depend on x. Indeed, at 330 K, electrical conductivity presents an optimum value for x = 0.25 with a value of σmax ≈ 2.2×105 S·m–1 whereas the Seebeck coefficient decreases when x and/or the temperature increases. The Ba-substituted LaCoO3 samples exhibit p-type semiconducting behaviour. The best power factor value found is 3.4×10–4 W·m–1·K–2 at 330 K for x = 0.075, which is 10% higher than the optimum value measured in La1–xSrxCoO3 for x = 0.05. The thermal diffusivity and thermal conductivity increase with increasing temperature and Ba concentration. La1-xBaxCoO3 shows a maximum figure of merit(ZT = 0.048) for x = 0.05 at 330 K, 25% higher than the best value in La1–xSrxCoO3 compounds.

Normalization Using Weighted Negative Second Order Exponential Error Functions(NeONORM) Provides Robustness Against Asym-metries in Comparative Transcriptome Profiles and Avoids False Calls

引用

Genomics, Proteomics & Bioinformatics 2006年第2期4卷 90-109页

作者： Sebastian Noth guillaume Brysbaert Arndt Benecke Systems Epigenomics Group Institut des Hautes Etudes Scientifiques/Institut de Recherches InterdisciplinairesCNRS/INSERM 91440 Bures sur Yvette France.

Studies on high-throughput global gene expression using microarray technology have generated ever larger amounts of systematic transcriptome data. A major challenge in exploiting these heterogeneous datasets is how to normalize the expression profiles by inter-assay methods. Different non-linear and linear normalization methods have been developed, which essentially rely on the hypothesis that the true or perceived logarithmic fold-change distributions between two different assays are symmetric in nature. However, asymmetric gene expression changes are frequently observed, leading to suboptimal normalization results and in consequence potentially to thousands of false calls. Therefore, we have specifically investigated asymmetric comparative transcriptome profiles and developed the normalization using weighted negative second order exponential error functions （NeONORM） for robust and global inter-assay normalization. NeONORM efficiently damps true gene regulatory events in order to minimize their misleading impact on the norrealization process. We evaluated NeONORM＇s applicability using artificial and true experimental datasets, both of which demonstrated that NeONORM could be systematically applied to inter-assay and inter-condition comparisons.

Generation of Synthetic Transcriptome Data with Defined Statistical Properties for the Development and Testing of New Analysis Methods

引用

Genomics, Proteomics & Bioinformatics 2007年第1期5卷 45-52页

作者： guillaume Brysbaert Sebastian Noth Arndt Benecke Systems Epigenomics Group Institut des Hautes Etudes Scientifiques/Institut de Recherches InterdisciplinairesCNRS/INSERM 91440 Bures sur Yvette France

We have previously developed a combined signal/variance distribution model that accounts for the particular statistical properties of datasets generated on the Applied Biosystems AB1700 transcriptome system. Here we show that this model can be efficiently used to generate synthetic datasets with statistical properties virtually identical to those of the actual data by aid of the JAVA application *** creator 1.0 that we have developed. The fundamentally different structure of AB1700 transcriptome profiles requires re-evaluation, adaptation, or even redevelopment of many of the standard microarray analysis methods in order to avoid misinterpretation of the data on the one hand, and to draw full benefit from their increased specificity and sensitivity on the other hand. Our composite data model and the *** creator 1.0 application thereby not only present proof of the correctness of our parameter estimation, but also provide a tool for the generation of synthetic test data that will be useful for further development and testing of analysis methods.

Background: Psychological stress and recovery monitoring is a key issue for increasing athletes' health, well-being, and performance. This multistudy report examined changes and the doseàresponse relationships between recoveryàstress psychological states, training load(TL), heart rate(HR), heart rate recovery(HRR), and heart rate variability(HRV) while providing evidence for the factorial validity of a short French version of the RecoveryàStress Questionnaire for Athletes(RESTQ-36-R-Sport).Methods: Four hundred and seventy-three university athletes(Study 1), 72 full expert swimmers(Study 2), and 11 national to international swimmers(Study 3) participated in the study. Data were analyzed through confirmatory factor analyses(Study 1), repeated ANOVAs and correlational analyses(Study 2), t tests and correlational analyses(Study 3).Results: Multiple-group confirmatory factor analyses showed that the RESTQ-36-R-Sport scores were partially invariant across gender, type of sport, and practice level(Study 1). A doseàresponse relationship was performed between TL and RESTQ-36-R-Sport scores during an ecological training program(Study 2). Finally, relationships were found between physiological(HRR) and psychological(RESTQ-36-R-Sport) states during an ecological tapering period leading to a national championship(Study 3).Conclusion: As a whole, these findings provided evidence for the usefulness of the short version of the RESTQ-36-R-Sport for regular monitoring to prevent potential maladaptation due to intensive competitive sport practice.

Iron deficiency without anemia and iron deficiency anemia are common and frequently overlooked complications of inflammatory bowel disease. Despite the frequency and impact of iron deficiency in inflammatory bowel disease, there are gaps in our understanding about its incidence, prevalence and natural history and, consequently, patients may be undertreated. Medical registries have a key role in collecting data on the disease's natural history, the safety and effectiveness of drugs in routine clinical practice, and the quality of care delivered by healthcare services. Even though iron deficiency impacts inflammatory bowel disease patients and healthcare systems substantially, none of the established European inflammatory bowel disease registries systematically collects information on iron parameters and related outcomes. Collection of robust iron parameter data from patient registries is one way to heighten awareness about the importance of iron deficiency in this disease and to generate data to improve the quality of patient care, patient outcomes, and thus quality of life. This objective could be achieved through collection of specific laboratory, clinical, and patientreported measurements that could be incorporated into existing registries. This review describes the status of current European inflammatory bowel disease registries and the data they generate, in order to highlight their potential role in collecting iron data, to discuss how such information gathering could contribute to our understanding of iron deficiency anemia, and to provide practical information in regard to the incorporation of accumulated iron parameter data into registries.
