| 1 | The Turbulent Schmidt Number for Transient Contaminant Dispersion in a Large Ventilated Room Using a Realizable k-εModel显示文摘Buildings with large open spaces in which chemicals are handled are often exposed to the risk of explosions.Computational fluid dynamics is a useful and convenient way to investigate contaminant dispersion in such large spaces.The turbulent Schmidt number(Sct)concept has typically been used in this regard,and most studies have adopted a default value.We studied the concentration distribution for sulfur hexafluoride(SF6)assuming different emission rates and considering the effect of Sct.Then we examined the same problem for a light gas by assuming hydrogen gas(H2)as the contaminant.When SF6 was considered as the contaminant gas,a variation in the emission rate completely changed the concentration distribution.When the emission rate was low,the gravitational effect did not take place.For both low and high emission rates,an increase in Sct accelerated the transport rate of SF6.In contrast,for H2 as the contaminant gas,a larger Sct could induce a decrease in the H2 transport rate. | Fei Wang Qinpeng Meng Jinchi Zhao Xin Wang Yuhong Liu Qianru Zhang | 2024 | Fluid Dynamics & Materials Processing2024，20，4： | 0 |
| 2 | Spatial Distribution of Parvalbumin-Positive Fibers in the Mouse Brain and Their Alterations in Mouse Models of Temporal Lobe Epilepsy and Parkinson’s Disease显示文摘Parvalbumin interneurons belong to the major types of GABAergic interneurons.Although the distribution and pathological alterations of parvalbumin interneuron somata have been widely studied,the distribution and vulnerability of the neurites and fibers extending from parvalbumin interneurons have not been detailly interrogated.Through the Cre recombinase-reporter system,we visualized parvalbumin-positive fibers and thoroughly investigated their spatial distribution in the mouse brain.We found that parvalbumin fibers are widely distributed in the brain with specific morphological characteristics in different regions,among which the cortex and thalamus exhibited the most intense parvalbumin signals.In regions such as the striatum and optic tract,even long-range thick parvalbumin projections were detected.Furthermore,in mouse models of temporal lobe epilepsy and Parkinson’s disease,parvalbumin fibers suffered both massive and subtle morphological alterations.Our study provides an overview of parvalbumin fibers in the brain and emphasizes the potential pathological implications of parvalbumin fiber alterations. | Changgeng Song Yan Zhao Jiajia Zhang Ziyi Dong Xin Kang Yuqi Pan Jinle Du Yiting Gao Haifeng Zhang Ye Xi Hui Ding Fang Kuang Wenting Wang Ceng Luo Zhengping Zhang Qinpeng Zhao Jiazhou Yang Wen Jiang Shengxi Wu Fang Gao | 2023 | Neuroscience Bulletin2023，39，11： | 0 |

| 4 | Spontaneous fusion after cervical disc arthroplasty:A case report and literature review显示文摘Objective:To report a rare case of spontaneous fusion(SF)following cervical disc arthroplasty(CDA),to review the related literature,and to propose a new measure to prevent it.Methods:The course of a patient with SF is described here.The potential causes,risk factors,and preventive measure of SF after CDA published in previous studies have also been reviewed and discussed.Results:A 63-year-old man presented with a 6-month history of progressive neck pain and developed left C-7 radiculopathy 4 years ago.Magnetic resonance imaging revealed disc herniation at the C6-C7 levels resulting in compression of the left C-7 nerve root.The patient underwent CDA at the C6-C7 levels,during which a PRESTIGE cervical disc device was implanted.He failed to follow up regularly as recommended postoperatively because he was completely free from the pain in his neck and left upper limb.Four years later,he was readmitted with a 2-month history of occasional neck stiffness.Plain radiographs indicated complete radiographic fusion of the C6-C7 levels with trabecular bone bridging surrounding the cervical disc prosthesis,and dynamic imaging showed no motion.He was seen at regular follow-up visits for up to 60 months without special treatment,as his symptoms of neck stiffness were minor and his symptom has not worsened since then.Conclusion:SF after CDA is a rare condition that can be attributed to patient-or prosthesis-related causes,and its risk factors are diverse.SF after CDA did not affect the patient’s clinical outcome,and no special treatment was required for it.Practitioners should be aware of this rare complication and advise patients of the risks before performing CDA. | 葛朝元 汪静 张斌飞 Hui Hao Shan Lequn Zhao Qinpeng Hao Dingjun | 2021 | 美中国际创伤杂志2021，20，2： | 0 |
