从2013年开始,作者团队使用自主研发电化学原理臭氧探空仪在华北平原北京地区进行每周一次观测.本研究首次使用2013-2019年期间北京地区臭氧探空数据评估Aqua卫星搭载大气红外探测仪(AIRS)和Aura卫星搭载微波临边探测器(MLS)反演垂直臭氧廓线,并对比臭氧探空,AIRS和Aura卫星搭载臭氧监测仪(OMI)臭氧柱总量结果.尽管臭氧探空与卫星反演垂直臭氧廓线在局部高度处差异较大,但整体来说两者较为接近(相对偏差大多<10%).臭氧探空,AIRS和OMI三种仪器测量臭氧柱总量的年变化特征较为一致,其年均臭氧柱总量分别为351.8±18.4 DU,348.8±19.5 DU和336.9±14.2 DU.后续对国内多站点观测数据分析将有助于进一步理解臭氧探空与卫星反演臭氧资料在不同区域的一致性.

Vaginal Birth after Cesarean after Zavanelli Maneuver: A Woman’s Right to Choose

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 1091-1095页

作者： Nicole Jenkins Gregory Vurture Jonathan D. baum Department of Obstetrics and Gynecology Jersey Shore University Medical Center Neptune NJ USA

Introduction: Vaginal birth after cesarean (VBAC) plays an essential role in lowering cesarean rates. Despite endorsement, trial of labor after cesarean (TOLAC) attempt rates remain low, in part due to fear of lawsuits. Zavanelli maneuver is a last resort procedure in the management of shoulder dystocia. We discuss a case of a woman determined to have a vaginal birth after her prior birth was complicated by shoulder dystocia requiring a Zavanelli maneuver. Her physicians were reluctant to allow her a TOLAC given her prior obstetric history. Case: A 34-year-old para 1 with prior cesarean delivery due to shoulder dystocia that required Zavanelli maneuver presents determined to pursue VBAC in her current pregnancy. She considered her delivery route options and addressed her modifiable risk factors. She consulted with multiple perinatologists who agreed that a TOLAC was reasonable, however she had to travel more than 70 miles (from Pennsylvania to New Jersey) to find an obstetrical practice and hospital willing to consider VBAC. She transferred care and the remainder of her prenatal course was uncomplicated. She went into labor at 41 weeks and had a successful VBAC without complication. In a thank you letter to her obstetrician, she described her birth experience as euphoric. Conclusion: This case illustrates how a woman’s choice of delivery route may be impacted by fear of litigation. Local providers focused on her prior delivery instead of her overall improved risk profile. Delivery route decisions should be based on a thorough evaluation of all risk factors and individualized to meet the reproductive goals of each woman. .

Synopsis of Leymus Hochst.(Triticeae:Poaceae)

引用

Journal of Systematics and Evolution 2009年第1期47卷 67-86页

作者： Bernard R.baum Eastern Cereals and Oilseeds Research Centre Agriculture and Agri-Food CanadaCentral Experimental Farm

Leymus is a genus in the Triticeae tribe, Poaceae. The taxa of this genus are allopolyploid species which possess the Ns and Xm genomes. According to cytological, cytogenetic and molecular genetic analyses, some species of Hystrix and Elymus ought to be transferred to this genus. A world revision of the genus Leymus is needed. In this paper we summarize experimental results, provide a key to sections, species and varieties, and list all the taxa we recognize in Leymus with their synonyms. This synopsis is a new taxonomic system to be used for the revision of Leymus.
