Purpose: This study was designed to study the effect of early use of the King Airway (KA) and impedance threshold device (ITD) in out-of-hospital cardiac arrest on ETCO2 as a surrogate measure of circulation, survival, and cerebral performance category (CPC) scores. After analysis of the first 9 month active period the KA was relegated to rescue airway status. Methods: This was a prospective pre-post study design. Patients >18 years with out-of-hospital cardiac caused arrest were included. Three periods were compared. In the first “non active” period conventional AHA 30/2 compression/ventilation ratio CPR was done with bag mask ventilation (BMV). No ITD was used. After advanced airway placement the compression/ventilation ratio was 10/1. In the second period continuous compressions were done. Primary airway management was a KA with an ITD. After placement of the KA the compression/ventilation ratio was 10/1. In the third period CPR reverted to 30/2 ratio with a two hand seal BMV with ITD. CPR ratio was 10/1 post endotracheal intubation (ETI) or KA. The KA was only recommended for failed BMV and ETI. Results: Survival to hospital discharge was similar in all three study periods. In Period 2 there was a strong trend to CPC scores >2. The study group hypothesized that the KA interfered with cerebral blood flow. For that reason the KA was abandoned as a primary airway. Comparing Period 1 to Period 3 there was a trend to improved survival in the bystander witnessed shockable rhythm (Utstein) subgroup, particularly if a metronome was used. ETCO2 was significantly increased in Period 2 and trended up in Period 3 when compared to Period 1. Advanced airway intervention had a highly significant negative association with survival. Conclusion: The introduction of an ITD into our system did not result in a statistically significant improvement in survival. The study groups were somewhat dissimilar. ETCO2 trended up. When comparing Period 1 to Period 3, the bundle of care was ass

Nodulation Capacity of Argentinean Soybean (<i>Glycine max</i>L. Merr) Cultivars Inoculated with Commercial Strains of <i>Bradyrhizobium japonicum</i>

引用

American Journal of Plant Sciences 2012年第1期3卷 130-140页

作者： Rubén Darío salvucci Monica Aulicino Mariangela Hungria Pedro Alberto Balatti 不详

The purpose of this research was to evaluate the nodulation potential of 31 Argentinean soybean commercial cultivars. Those with the highest nodulation capacity response developed twice the amount of nodules than the low nodulating ones, which is the variation contained in soybean genotypes. Furthermore, this was not due to bacterial promiscuity, since the response was independent of the bradyrhizobia strain inoculated. The ability of cultivars to develop a larger number and biomass of nodules was unrelated with the maturity group they belong to and also was not a response to quorum sensing effects. Our results suggest that breeding programs can be aimed at improving the nodulation capacity of soybean and that cultivars from different maturity groups can be a source of nodulation QTLs.

磷营养对烟草植株生长和非结构碳水化合物积累的影响

低磷营养通常导致叶片中淀粉积累的增加。本研究的目的是要确定,从缺乏到超过最适量的磷营养怎样影响植株的生长、发育和植株叶片内的非结构碳水化合物的积累。烟草植株(红花烟草 KY14和 G28及黄花烟草 Pumila)在温室内生长,盆内土壤包含六个(试验一)或七个(试验二)磷养分水平(P1～P7,变幅为0～2150kg/ha)。随着磷水平升到 P4,烟株生长加快,而到 P3(134kgP/ha)或 P4(269kgP/ha)时,烟叶中磷的含量大致保持稳定,超过 P4则植株生长稳定而叶片中磷含量继续增加。在高磷营养条件下,增加的叶片磷不影响非结构碳水化合物的积累。低于 P4时光合能力降低,但不如生长发育降低得多。叶片中蔗糖含量不受供磷水平的影响。淀粉含量受供磷水平的影响因栽培品种而异。对于 G28和 Pumila,低供磷水平会导致淀粉积累的减少,而 KY14,低供磷水平导致淀粉积累的增加。二磷酸腺苷葡萄糖(ADPG)、焦磷酸化酶活性与淀粉积累无关。所有(试验用)遗传型的烟草,从 P1到 P4总糖的积累都增加。结果表明,低磷营养不一定导致烟草淀粉积累的增加,更确切地说,这种作用依赖于烟草的栽培品种或种类。

波多黎各于20世纪90年代初才开始发展城市轨道交通,但因为善于利用后发优势,通过产学研的结合,充分考虑了地铁工程的多学科特性,走出一条有波多黎各特色的道路,成为美国和国际公共交通领域技术交流的典范。主要介绍了其产学研的项目,它由负责地铁项目的政府主管部门、波多黎各大学和美国麻省理工学院共同组织实施,历经地铁前期规划、修建、调试、运营和政策分析等全部过程,共13年的时间。这种方式提高了工程的质量和施工效率,推动当地轨道交通辅助产业的发展,加快了新技术的应用及研究,培养了一大批轨道交通的规划运营人才,为拉丁美洲城市轨道交通建设提供了一个新模式。波多黎各的经验对于我国当前的城市轨道交通建设同样具有借鉴意义。
