Nucleosides and Nucleotides are polydentate ligands, offering potential binding sites for metal ions. Energy interaction parameters: Slater Condon Fk (cm-1), Spin Orbit interaction ξ4f? (cm-1), Nephelauxetic Ratio (β), Bonding (b1/2) and Covalency (δ) parameter for the interaction of Pr(III) with Nucleoside and Nucleotide are evaluated to study the mode of binding of the Nucleic Acid Components (Guanosine and Guanosine Triphosphate) with Pr(III). Further Intensity Parameters like Oscillation Strength and Judd Ofelt Parameter (T2, T4, T6) have been evaluated to investigate degree of inner or outer sphere co-ordination of Pr(III) with Nucliec Acid ligands. Comperative Absorption Spectra in different solvents substantiate the informations, gathered from the evaluated values of both energy interaction and intensity parameters. Further evaluation of Thermodynamic parameters (ΔG, ΔH and ΔS) through Kinetic studies enable to provide the detailed information about the reaction pathways and thermodynamic behavour of the complexation process of neucleosides and nucleotides with Pr(III) and Ca2+.

OBJECTIVES: We evaluated the accuracy of a new 64- slice computed tomography(CT) scanner, compared with intravascular ultrasound, to visualize atherosclerosis in the proximal coronary system. BACKGROUND: Noninvasive determination of plaque composition and plaque burden may be important to improve risk stratification. mETHODS: In 20 patients, a 64- slice CT scan(Sensation 64, Siemens medical Solutions, Forchheim, Germany) and an intravascular ultrasound investigation of vessels without stenosis >50% was performed. Diagnostic image quality with 64- slice CT was obtained in 36 vessels in 19 patients. RESULTS: In these vessels, which were divided in 3- mm sections, 64- slice CT enabled a correct detection of plaque in 54 of 65(83% ) sections containing noncalcified plaques, 50 of 53(94% ) sections containing mixed plaques, and 41 of 43(95% ) sections containing calcified plaques. In 192 of 204(94% ) sections, atherosclerotic lesions were excluded correctly. In addition, 64- slice CT enabled the visualization of 7 of 10(70% ) sections revealing a lipid pool and could identify a spotty calcification pattern in 27 of 30(90% ) sections. The correlation coefficient to determine plaque volumes per vessel was r2=0.69(pmation of mixed and noncalcified plaque volumes(pmate calcified plaque volumes by 64- slice CT. The interobserver variability to determine plaque volumes was 37% . Interobserver agreement to identify atherosclerotic sections was good(Cohen’ s kappa coefficient=0.75). CONCLUSIONS:We conclude that 64- slice CT reveals encouraging results to noninvasively detect different types of coronary plaques located in the proximal coronary system. The ability to determine plaque burden currently is hampered by mainly an insufficient reproducibility.

摘要美国放射学委员会(ABR)提供放射诊断医师、专业及亚专业诊断专家的资质认证的历史已超过75年。资质认证过程是切实体现平衡专业利益与公众利益的社会合约的制定过程。一方面要保证医务人员在执业过程中有一定的自主权,另一方面要约束其执业时把病人的利益放第一位,还要保证执业者具有专业技能,并能够保障公众健康。ABR实现这一职责的首要工具是制定各类监督考查的基本标准。

Laparoscopic surgery is a new abdominal surgical procedure which helps the patients in many ways like less hospital stay, faster recovery and reduced pain. The main disadvantage in this surgical procedure is the reduced haptic perception by the surgeons due to the usage of laparoscopic instrument to handle tissues which in turn cause damage of it as compared to an open surgery. The primary aim of this investigation was to compare the pinch force applied during two different methods of laparoscopic grasping: Finger and Palm grasp. A low cost force sensing resistor tailor made for the grasper tip was designed and fabricated for quantifying the grasper tip force in the study. The results indicate more pinch force was applied during palm grasp as compared to finger grasp so as to prevent the slippage of the tissues from the jaws of the laparoscopic graspers.

1968年IgA肾病首次被描述，最初称为Berger病。先证者为法国患儿，表现为急性上呼吸道感染数天后出现无症状肉眼血尿。肾活检显示系膜区显著扩大、IgA沉积，因此被命名为IgA肾病。此后40年临床治疗实践中，对该病自然病程了解逐渐增多，但对其发病机制知之甚少。20世纪80年代，D，Amico和其他学者已经认识到IgA肾病是世界上最常见的肾小球肾炎。因此，Julian等指出该病对1％以上的人口有影响。

A strange phenomenon of fire taking place at Arruhban area west Bahr-Al Najaf area in Iraq was noticed in 2010 and smoke continued many months;this phenomenon reappeared many years later. This site is part of Bahr-Al Najaf-Iraq NE Arabian plate, located in flat area near an archeological site of christian temple called Tel Arruhban. To understand the causes for this fire in a non-residential area, field observations from repeated visits between 2010 and 2018 and on-site excavation operations were conducted. The results of analysis of soil samples, and on-site detection for gases and vapors showed that the phenomenon of burning and smoke generated at this site was due to external influences and that the presence of soil rich with organic materials helped to the existence of this phenomenon.

应用多层螺旋CT（mDCT）基于cT值的拓扑学提出一个新的、强有力的算法，用于肺组织的分类，并与密度测量法得到的结果比较。21例有或无肺部病变者（肺气肿，纤维化）行mDCT胸部检查（各项同性的体素大小，边长0．6mm），获得了275个立方感兴趣区（VOI，边长40个像素）。2名放射医师对所有的VOI进行观察，并作一致分类，分别以minkowski函数值（mF）及CT密度值判定组织特征。
