| 1 | Imaging evaluation of hemoptysis in children显示文摘Hemoptysis is an uncommon but distressing symptom in children. It poses a diagnostic challenge as it is difficult to elicit a clear history and perform thorough physical examination in a child. The cause of hemoptysis in children can vary with the child's age. It can range from infection, milk protein allergy and congenital heart disease in early childhood, to vasculitis, bronchial tumor and bronchiectasis in older children. Acute lower respiratory tract infections are the most common cause of pediatric hemoptysis. The objective of imaging is to identify the source of bleeding, underlying primary cause, and serve as a roadmap for invasive procedures. Hemoptysis originates primarily from the bronchial arteries. The imaging modalities available for the diagnostic evaluation of hemoptysis include chest radiography, multi-detector computed tomography(MDCT), magnetic resonance imaging(MRI) and catheter angiography. Chest radiography is the initial screening tool. It can help in lateralizing the bleeding with high degree of accuracy and can detect several parenchymal and pleural abnormalities. However, it may be normal in up to 30% cases. MDCT is a rapid, non-invasive multiplanar imaging modality. It aids in evaluation of hemoptysis by depiction of underlying disease, assessment of consequences of hemorrhage and provides panoramic view of the thoracic vasculature. The various structures which need to be assessed carefully include the pulmonary parenchyma, tracheobronchial tree, pulmonary arteries, bronchial arteries and non-bronchial systemic arteries. Since the use of MDCT entails radiation exposure, optimal low dose protocols should be used so as to keep radiation dose as low as reasonably achievable. MRI and catheter angiography have limited application. | Divya Singh Ashu Seith Bhalla Prasad Thotton Veedu Arundeep Arora | 2013 | World Journal of Clinical Pediatrics2013，2，4： | 12 |
| 2 | CT patterns of nodal disease in pediatric chest tuberculosis显示文摘AIM:To highlight various patterns of nodal involvement and post treatment changes in pediatric chest tuberculosis based on contrast enhanced computed tomography(CECT) scans of chest.METHODS:This was a retrospective study consisting of 91 patients aged less than 17 years,who attended Paediatrics OPD of All India Institute of Medical Sciences with clinically diagnosed tuberculosis or with chest radiographs suggestive of chest tuberculosis.These patients had an initial chest radiograph as well as CECT of the chest and follow up imaging after 6 mo,and in some cases 9 mo,of completion of anti-tubercular treatment(ATT).CECT of these patients was reviewed for the location and extent of nodal involvement along with determination of site,size,enhancement pattern and calcification.RESULTS:Enlargement of mediastinal or hilar lymph nodes was found in 88/91 patients(96.7%),with the most common locations being paratracheal(84.1%),and subcarinal(76.1%).The most common pattern of enhancement was found to be inhomogenous.The nodes were conglomerate in 56.8% and discrete in 43.2%.In addition,perinodal fat was obscured in 84.1% of patients.In the post-treatment scan,there was 87.4% reduction in the size of the nodes.All nodes post-treatment were discrete and homogenous with perinodal fat present.Calcification was found both pre-and post-treatment,but there was an increase in incidence after treatment(41.7%).There was hence a reduction in size,change in enhancement pattern,and appearance of perinodal fat with treatment.CONCLUSION:Tubercular nodes have varied appearance and enhancement pattern.Conglomeration and obscuration of perinodal fat suggest activity.In residual nodes decision to continue ATT requires clinical correlation. | Amar Mukund Rashmi Khurana Ashu S Bhalla Arun K Gupta Sushil K Kabra | 2011 | World Journal of Radiology2011，3，1： | 5 |
| 3 | Pediatric vs adult pulmonary tuberculosis:A retrospective computed tomography study显示文摘AIM: To compare the manifestations of chest tuberculosis(TB) in pediatric and adult patients based on contrast enhanced computed tomography of chest.METHODS: This was a retrospective study consisting of 152 patients of chest TB including 48 children and 104 adults who had undergone contrast enhanced computed tomography of chest prior to treatment. The patterns and severity of parenchymal, mediastinal and pleural manifestations were analyzed and compared among different age groups.RESULTS: Parenchymal changes observed include consolidation, air space nodules, miliary TB, cavitation, bronchiectasis and fibrosis and these were noted in 60% of children, 71% of adolescents and 76.9% of adults. These changes were more common in right upper lobe in all age groups. There was no significant difference in the frequency of these changes(except nodules) in different age groups. Centrilobular nodules were seen less commonly in children less than 10 years(P = 0.028). Pleural effusion was noted in 28(18.42%) patients and pericardial effusion in 8(5.3%) patients. No significant difference in the serosal involvement is seen among children and adults. Mediastinal adenopathy was seen 70% of children, 76.3% adolescents and 76.9% of adults and paratracheal nodes were seen most frequently. Nodes had similar features(except matting) among all age groups. Matting of nodes was seen more commonly in children(P = 0.014). CONCLUSION: Pediatric chest tuberculosis can have severe parenchymal lesions and nodal involvement similar to adults. The destructive lung changes observed in children needs immediate attention in view of the longer life span they have and hence in formulating optimal treatment strategies. | Prasad Thotton Veedu Ashu Seith Bhalla Sreenivas Vishnubhatla Sushil Kumar Kabra Arundeep Arora Divya Singh Arun Kumar Gupta | 2013 | World Journal of Clinical Pediatrics2013，2，4： | 2 |
| 4 | 预热辅助搅拌摩擦焊AA6061-T6和AA7075-T651合金的冶金性能和振声信号变化(英文)显示文摘研究AA6061-T6和AA7075-T651合金在搅拌摩擦焊接(FSW)过程中搅拌头形状(圆柱形和方形)、圆柱形搅拌头偏心距(0.5 mm和1mm)和预热(二次加热)对合金冶金性能、振声信号波形变化和接头强度的影响。观察到偏心针能提供良好的流动性和异种金属间的混合,增大搅拌区尺寸,细化搅拌区晶粒尺寸。当轴肩突然插入时,振声信号强度增加;当轴肩到达所需深度时,信号强度减小。与搅拌头插入过程相比,在焊接过程中产生的信号强度更高,这是由于搅拌头在沿焊接轨道运动过程中会不断吸收新的材料。在搅拌针插入前和焊接过程中对工件进行预热可显著影响焊料流动行为和混合形式。与未预热的样品相比,预热后样品中搅拌区的晶粒更粗大,且预热后信号强度明显下降。采用额外加热后,焊接接头的拉伸强度和抗弯强度略有提高。 | Ashu GARG Madhav RATURI Anirban BHATTACHARYA | 2019 | Transactions of Nonferrous Metals Society of China2019，29，8： | 2 |

| 9 | Intraparotid facial nerve schwannoma: A case report显示文摘Facial nerve schwannoma occurring within the parotid gland is a rare tumour. We report a case of schwannoma within the parotid gland in a young female patient, who underwent ultrasound and magnetic resonanceimaging(MRI) and subsequent surgical excision of the lesion. The lesion showed hyperintensity on T2-weighted and diffusion-weighted MRI. There was no adjacent lymphadenopathy. Although hyperintensity on diffusionweighted MRI could suggest malignant tumours, the characteristic 'string sign' provided the clue for the diagnosis of schwannoma. | Abhishek Jaiswal Asit Ranjan Mridha Devajit Nath Ashu Seith Bhalla Alok Thakkar | 2015 | World Journal of Clinical Cases2015，3，3： | 1 |

| 14 | Tracing the impact of stack configuration on interface resistances in reverse electrodialysis by in situ electrochemical impedance spectroscopy显示文摘Reverse electrodialysis(RED)is an emerging membrane-based technology for the production of renewable energy from mixing waters with different salinities.Herein,the impact of the stack configuration on the Ohmic and non-Ohmic resistances as well as the performance of RED were systematically studied by using in situ electrochemical impedance spectroscopy(EIS).Three different parameters(membrane type,number of cell pairs and spacer design)were controlled.The Ohmic and non-Ohmic resistances were evaluated for RED stacks equipped with two types of commercial membranes(Type I and Type II)supplied by Fujifilm Manufacturing Europe B.V:Type I Fuji membranes displayed higher Ohmic and non-Ohmic resistances than Type II membranes,which was mainly attributed to the difference in fixed charge density.The output power of the stack was observed to decrease with the increasing number of cell pairs mainly due to the increase in ionic shortcut currents.With the reduction in spacer thickness from 750 to 200μm,the permselectivity of membranes in the stack decreased from 0.86 to 0.79 whereas the energy efificiency losses increased from 31%to 49%.Overall,the output of the present study provides a basis for understanding the impact of stack design on internal losses during the scaling-up of RED. | Wenjuan Zhang Bo Han Ramato Ashu Tufa Chuyang Tang Xunuo Liu Ge Zhang Jing Chang Rui Zhang Rong Mu Caihong Liu Dan Song Junjing Li Jun Ma Yufeng Zhang | 2022 | Frontiers of Environmental Science & Engineering2022，16，4： | 1 |
