The inherent noise in positron emission tomography (PET) leads to the instability of quantitative indicators, which may affect the diagnostic accuracy for differentiating malignant and benign lesions in the management of lung cancer. In this paper, the reliability of retention index (RI) is systematically investigated by using computer simulation for the dual-time-point imaging protocol. The area under the receiver operating characteristic (ROC) curve is used to evaluate the optimal protocol. Results demonstrate that the reliability of RI is affected by several factors including noise level, lesion type, and imaging schedule. The ris with small absolute values suffer from worse reliability than those larger ones. The results of ROC curves show that over delayed second scan cannot help to improve the diagnostic performance further, while an early first scan is expected. The method of optimization based on ROC analysis can be easily extended to comprise as many lesions as possible.

以扬稻6号为试验对象,通过在人工气候箱中进行高温处理,研究抽穗期高温胁迫对水稻剑叶生理特性的影响,旨在深入探讨高温对水稻的伤害机理。研究表明:高温胁迫加速剑叶叶绿素丧失,使超氧化物歧化酶(SOD)活性以及抗坏血酸(ASA)、还原型谷胱甘肽(GSH)、脯氨酸(Pro)、可溶性蛋白质和可溶性糖含量明显降低,并使细胞膜透性和丙二醛(MDA)含量显著增加。说明高温可加速叶片衰老,并影响植物体其他内源物质的变化,且有可能进一步降低作物光合能力。

High spin states of the odd proton nucleus 123I have been populated in the reaction 116Cd(14N, 5n2p) at a beam energy of 65MeV. Two previously known positive-parity ΔI = 2 sequences have been extended up to 31/2+ and 41/2+. In addition, a number of ΔI = 1 transitions linking the two ΔI = 2 sequences have been observed. It is suggested that both the ΔI = 2 sequences are built upon the oblate πg7/2[404]7/2+ Nilsson configuration.

The primary objective of this paper was to identify flood-prone areas in Southeast of Louisiana to help decision-makers to develop appropriate adaptation strategies and flood prediction, and mitigation of the effects on the community. In doing so, the paper uses satellite remote sensing and Geographic Information System (GIS) data for this purpose. Elevation data was obtained from the National Elevation Dataset (NED) produced by the United States Geological Survey (USGS) seamless data warehouse. Satellite data was also acquired from USGS Earth explorer website. Topographical information on runoff characteristics such as slope, aspect and the digital elevation model was generated. Grid interpolation TIN (triangulated irregular network) was carried from the digital elevation model (DEM) to create slope map. Image Drape was performed using ERDAS IMAGINE Virtual GIS. The output image was then draped over the NED elevation data for visualization purposes with vertical exaggeration of 16 feet. Results of the study revealed that majority of the study area lies in low-lying and very low-lying terrain below sea level. Policy recommendation in the form of the need to design and build a comprehensive Regional Information Systems (ris) in the form of periodic inventorying, monitoring and evaluation with full support of the governments was made for the study area.

To assess the role of cardiovascular morbidity, its risk factors, and microalb uminuria in the development of inflammatory cystoid macular edema (CME). A match ed case-control study. study population: We included 24 consecutive patients wi th uveitis and CME. Twenty four uveitis patients without CME, matched for age an d duration of uveitis served as controls. intervention and observation procedure s: Patients and controls were interviewed for the presence of cardiovascular ris k factors and cardiovascular morbidity. All medications were registered. Morning urinary albumin concentration was measured, as well as blood pressure, C-react ive protein, and creatinine in blood. Patients suffering from diabetes mellitus were excluded from this study. main outcome measures: The presence of cardiovasc ular morbidity and its risk factors and microalbuminuria in uveitis patients wit h and without CME. We found a positive association between trace-and/or microal buminuria and inflammatory CME (P=. 001; odds ratio 13.0, 95%CI 2.5 to 68.1 and P=. 015; odds ratio 5.9, 95%CI 1.6 to 22.6), but no relation between CME and c ardiovascular morbidity or its risk factors. No additional association between t race-and/or any microalbuminuria and general characteristics of patients, speci fic factors related to general disease as a cause of ocular inflammation, locati on of uveitis, duration of uveitis, and medication was found. The presence of tr ace-and/or microalbuminuria in inflammatory CME might indicate the presence of early systemic vascular disease and carry the risk of developing CME. This findi ng brings new insight into the pathogenesis of CME and could open up new avenues for the treatment of CME.

De barsy综合征

世界核心医学期刊文摘（皮肤病学分册） 2005年第2期1卷 47-47页

作者： Guerra D. Fornieri C. bacchelli b. 崔荣 Department of biomedical Sciences Univ. of Modena and Reggio Emilia Via Campi 287 41100-Modena Italy Dr.

background: In 1968, De barsy reported on a girl exhibiting an aged aspect, ’dwarfism, oligophrenia, and degeneration of the elastic tissue in cornea and skin’. The disorder was recognized as a subgroup of cutis laxa syndrome and termed De barsy-Moens-Dierckx syndrome. The pathogenesis of the disorder is unknown. Methods: To improve the comprehension of the pathogenetic mechanisms involved in the De barsy syndrome, we performed an ultrastructural, morphometric, immunocytochemical study on a skin biopsy of a boy with the De barsy phenotype, who has been clinically followed for 12 years from birth. Moreover, the lysyl oxidase activity was measured on skin fibroblasts cultured in vitro. Results: Light and electron microscopy, morphometry, and immunocytochemical observations showed a significant reduction of the elastic fibers in the papillary and in the reticular dermis of patient compared to an age-matched control (P by contrast, the collagen structure, content, and the distribution were normal, as well as lysyl oxidase activity in the medium of in vitro fibroblasts (12,323 DPM/106 cells). The immunoreaction for antibodies recognizing fibrillin-1, neutrophilic elastase, and tumor necrosis factor-αwas stronger, whereas that for antibodies against transforming growth factor-βwas less pronounced in the dermis of the De barsy boy compared to control. Conclusions: Clinical, phenotypic, and structural data were consistent with the diagnosis of De barsy syndrome. This is the first case described in Italy. Clinical and structural data confirm that the elastic component is mostly affected in this disorder. Moreover, ultrastructural and immunochemical findings suggest that both elastic fiber degradative and very likely synthetic processes are involved.
