| 1 | 北喜马拉雅萨迦穹窿中苦堆和萨迦淡色花岗岩的U-Pb年龄及其地质意义显示文摘利用TIMS方法,对产于北喜马拉雅萨迦穹窿中的苦堆和萨迦淡色花岗岩锆石、独居石和磷钇矿进行了U-Pb定年.结果表明,苦堆淡色花岗岩的岩浆结晶年龄为27.5±0.5Ma,而萨迦淡色花岗岩的岩浆结晶年龄为14.4±0.2Ma,因此将北喜马拉雅淡色花岗岩形成的时间跨度从原有的15~10Ma扩展到27.5~10Ma,并据此对北喜马拉雅淡色花岗岩的成因机制进行了年代学制约,指出北喜马拉雅淡色花岗岩有着多样的成因机制. | 张宏飞 N.Harris R.Parrish 张利 赵志丹 | 2004 | 科学通报2004,49,20: | 33 |
| 2 | Evidence and explanation for the involvement of the nucleus accumbens in pain processing显示文摘The nucleus accumbens(NAc)is a subcortical brain structure known primarily for its roles in pleasure,reward,and addiction.Despite less focus on the NAc in pain research,it also plays a large role in the mediation of pain and is effective as a source of analgesia.Evidence for this involvement lies in the NAc’s cortical connections,functions,pharmacology,and therapeutic targeting.The NAc projects to and receives information from notable pain structures,such as the prefrontal cortex,anterior cingulate cortex,periaqueductal gray,habenula,thalamus,etc.Additionally,the NAc and other pain-modulating structures share functions involving opioid regulation and motivational and emotional processing,which each work beyond simply the rewarding experience of pain offset.Pharmacologically speaking,the NAc responds heavily to painful stimuli,due to its high density ofμopioid receptors and the activation of several different neurotransmitter systems in the NAc,such as opioids,dopamine,calcitonin gene-related peptide,γ-aminobutyric acid,glutamate,and substance P,each of which have been shown to elicit analgesic effects.In both preclinical and clinical models,deep brain stimulation of the NAc has elicited successful analgesia.The multi-functional NAc is important in motivational behavior,and the motivation for avoiding pain is just as important to survival as the motivation for seeking pleasure.It is possible,then,that the NAc must be involved in both pleasure and pain in order to help determine the motivational salience of positive and negative events. | Haley N.Harris Yuan B.Peng | 2020 | Neural Regeneration Research2020,15,4: | 3 |

| 5 | Rootstock effects on scion phenotypes in a‘Chambourcin’experimental vineyard显示文摘Understanding how root systems modulate shoot system phenotypes is a fundamental question in plant biology and will be useful in developing resilient agricultural crops.Grafting is a common horticultural practice that joins the roots(rootstock)of one plant to the shoot(scion)of another,providing an excellent method for investigating how these two organ systems affect each other.In this study,we used the French-American hybrid grapevine‘Chambourcin’(Vitis L.)as a model to explore the rootstock–scion relationship.We examined leaf shape,ion concentrations,and gene expression in‘Chambourcin’grown ungrafted as well as grafted to three different rootstocks(‘SO4’,‘1103P’and‘3309C’)across 2 years and three different irrigation treatments.We found that a significant amount of the variation in leaf shape could be explained by the interaction between rootstock and irrigation.For ion concentrations,the primary source of variation identified was the position of a leaf in a shoot,although rootstock and rootstock by irrigation interaction also explained a significant amount of variation for most ions.Lastly,we found rootstock-specific patterns of gene expression in grafted plants when compared to ungrafted vines.Thus,our work reveals the subtle and complex effect of grafting on‘Chambourcin’leaf morphology,ionomics,and gene expression. | ZoëMigicovsky Zachary N.Harris Laura LKlein Mao Li Adam McDermaid Daniel H.Chitwood Anne Fennell Laszlo G.Kovacs Misha Kwasniewski Jason P.Londo Qin Ma Allison J.Miller | 2019 | Horticulture Research2019,6,1: | 1 |
