Tumor-protein 53(p53)is a transcription factor(TF)encoded by TP53(Trp53 in mice)and is a master regulator of tumor-suppressive programs'.Importantly,TP53 is the most frequently mutated gene in human cancer,and its loss of function contributes to tumor development,exemplified by variable p53 mutations detected in 50%-75%of pancreatic cancers.2 From these perceptions,a number of targets transcribed by p53 that confer tumor suppression have been ***,our understanding of how p53 prevents normal cells from initiating tumorigenesis is still *** complement this limitation,herein,we established a new approach to identify underlying effectors transcribed by p53 in normal physiology.

Background: Fetal Alcohol Spectrum Disorders (FASDs) are a global public health concern with lifelong consequences for affected individuals. Recent prevalence studies suggest FASD prevalence rates range from 1-5% among school age children. Most people with FASD are not correctly diagnosed and inadequate screening to identify patients with increased risk may contribute to under-diagnosis. This study developed a 10-item screening tool for FASD and examined its feasibility. Methods: The sample consisted of 355 children who had been evaluated at an FASD clinic. Data from the 33-item Alcohol Related Neurodevelopmental Disorder Behavioral Checklist was used to develop a brief FASD screen by comparing the changes in Cronbach’s alpha for different combinations of items. The validity of the brief scale was then further examined using receiving operating characteristic analyses. Results: The 10-item screen demonstrated acceptable sensitivity, specificity, and accuracy to identify children at high risk for FASD. The percentage correctly classified was 91.3 and the area under the receiving operating characteristic curve was 0.971. Conclusions: This feasibility study demonstrated that a screen for FASD consisting of 10 items with yes or no responses can be completed in 3 - 4 minutes. The tool is brief, with a low administration burden and has acceptable epidemiologic performance characteristics including accuracy. Future research should examine the performance of this tool when used in larger, community-based populations where screening for FASD would be appropriate.

Stomatal movements are critical in regulating gas exchange for photosynthesis and water balance between plant tissues and the atmosphere. The plant hormone abscisic acid （ABA） plays key roles in regulating stomatal closure under various abiotic stresses. In this study, we revealed a novel role of BAKI in guard cell ABA signaling. We found that the brassinosteroid （BR） signaling mutant bakl lost more water than wild- type plants and showed ABA insensitivity in stomatal closure. ABA-induced OST1 expression and reactive oxygen species （ROS） production were also impaired in bakl. Unlike direct treatment with H202, overex-pression of OST1 did not completely rescue the insensitivity of bakl to ABA. We demonstrated that BAK1 forms a complex with OST1 near the plasma membrane and that the BAKI/OST1 complex is increased in response to ABA in planta. Brassinolide, the most active BR, exerted a negative effect on ABA-induced formation of the BAK1/OST1 complex and OST1 expression. Moreover, we found that BAK1 and ABI1 oppositely regulate OST1 phosphorylation in vitro, and that ABI1 interacts with BAK1 and inhibits the interaction of BAK1 and OST1. Taken together, our results suggest that BAK1 regulates ABA-induced stomatal closure in guard cells.

Kinetics model was developed for the mixed （steam and dry） reforming of methane, which is useful for the control of H2/CO ratio. The equilibrium constants of reaction rate were determined using the experimental equilibrium data at different reaction temperatures, while the forward reaction rate constants were estimated using the experimental data under non-equilibrium （high inert fraction and high space velocity） conditions. The comparison between calculated and experimental data clearly showed that the developed model described satisfactorily, and further analysis using the parametric sensitivity determined the wall temperature and CO2 fraction in the feed gas as effective parameters for the manipulation of CH4 conversion and H2/CO ratio of synthesis gas under the equilibrium condition. Meanwhile, the inert fraction, rather than the residence time, was selected as additional parameter under non-equilibrium condition.
