2不同发病年龄强迫症患者6种功能基因的分子遗传学研究显示文摘目的探讨与5-羟色胺和多巴胺递质系统有关的基因在强迫症发病中的作用。方法收集120个强迫症的核心家系,按患者的发病年龄分为≤16岁组和>16岁组,应用基因扩增的限制性片段长度多态和数目可变的顺向重复多态技术对强迫症核心家系在5-羟色胺2A受体基因、5-羟色胺转运体(5-HTT)基因、多巴胺D2受体(DRD2)基因、多巴胺D4受体(DRD4)基因、儿茶酚氧位甲基转移酶(C0MT)基因、单胺氧化酶A(MAO-A)基因等6个基因的7个位点进行传递不平衡检测和数量性状的传递不平衡检测以及DRD4基因的单体型分析。结果 (1)未发现6个功能基因与强迫症存在传递不平衡;(2)DRIY2-141C Del/Ins多态性与≤16岁组存在传递不平衡(X2=3.98,P=0.04),COMT-Val/Met多态性与>16岁组存在传递不平衡(X2=3.65,P=0.05),经相关分析,这两个位点与强迫症的发病年龄相关(DRD2:r=-0.29,P=0.002;COMT:r=-0.19,P=0.04)。结论DRD2基因和COMT基因可能与不同发病年龄的强迫症病因相关。张岚 刘协和 李涛 杨彦春 胡迅 David Collier 2004中华精神科杂志2004,37,4:4

17Estimating the subsolar magnetopause position from soft X-ray images using a low-pass image filter显示文摘The Lunar Environment heliospheric X-ray Imager(LEXI)and Solar wind Magnetosphere Ionosphere Link Explorer(SMILE)missions will image the Earth’s dayside magneto pause and cusps in soft X-rays after their respective launches in the near future,to specify glo bal magnetic reconnection modes for varying solar wind conditions.To suppo rt the success of these scientific missions,it is critical to develop techniques that extract the magnetopause locations from the observed soft X-ray images.In this research,we introduce a new geometric equation that calculates the subsolar magnetopause position(RS)from a satellite position,the look direction of the instrument,and the angle at which the X-ray emission is maximized.Two assumptions are used in this method:(1)The look direction where soft X-ray emissions are maximized lies tangent to the magnetopause,and(2)the magnetopause surface near the subsolar point is almost spherical and thus RSis nea rly equal to the radius of the magneto pause curvature.We create synthetic soft X-ray images by using the Open Geospace General Circulation Model(OpenGGCM)global magnetohydrodynamic model,the galactic background,the instrument point spread function,and Poisson noise.We then apply the fast Fourier transform and Gaussian low-pass filte rs to the synthetic images to re move noise and obtain accurate look angles for the soft X-ray pea ks.From the filte red images,we calculate RS and its accuracy for different LEXI locations,look directions,and solar wind densities by using the OpenGGCM subsolar magnetopause location as ground truth.Our method estimates RS with an accuracy of<0.3 RE when the solar wind density exceeds>10 cm-3.The accuracy improves for greater solar wind densities and during southward interplanetary magnetic fields.The method ca ptures the magnetopause motion during southwa rd interplaneta ry magnetic field turnings.Consequently,the technique will enable quantitative analysis of the magnetopause motion and help reveal the dayside reconnection modes for dynamic solar wind conditions.This technique will suppo rt the LEXI and SMILE missions in achieving their scientific o bjectives.Hyangpyo Kim Hyunju K.Connor Jaewoong Jung Brian M.Walsh David Sibeck Kip D.Kuntz Frederick S.Porter Catriana K.Paw U Rousseau A.Nutter Ramiz Qudsi Rumi Nakamura Michael Collier 2024Earth and Planetary Physics2024,8,1:1
