乙烯调节着高等植物的许多生理和发育过程,包括果实成熟、叶脱落、衰老和伤反应.虽然在果实成熟和叶片衰老过程中,mRNA的积累与乙烯的产量以及感量相关,但控制乙烯合成的调节机制以及乙烯促进基因表达的机理并不清楚.此前我们曾报告,互补DNA pTOM13与某种mRNA的作用相同,而这种mRNA的合成与趋熟果实及受伤叶片中乙烯的合成相关.pTOM13 mRNA编码一种相对分子量约35 000的蛋白.对cDNA和兰个相关基因的克隆以及测序已经完成,但该蛋白质的作用尚未知道.我们认为,应用pTOM13时,反义RNA降低了乙烯的生物合成,降低程度与反义RNA量的多少相关,而反义RNA以前仅用于抑制已知功能的基因表述.对这些新型突变体进行的分析表明,pTOM13编码一种多肽,该多肽包含在乙烯合成酶(Acc氧化酶)所催化的1-氨基环丙烷-1-羧酸转化为乙烯的过程中.

本文是对国际糖尿病足工作组(IWGDF)2019年指南的更新,针对在日常临床工作中使用的糖尿病伴足溃疡的分类提出了新指南。本指南基于对现有文献的系统综述,确定了149篇文献中涉及的28种分类,随后使用推荐、评估、发展和评价分级(GRADE)方法获取了专家意见。首先,我们通过对诊断试验的判断总结,制定了一份可能适合在临床实践中使用的分类系统的清单,重点关注每个系统在预测溃疡相关并发症的可用性、准确性和可靠性以及资源可及性。其次,经过小组讨论和共识研讨,我们确定了哪些分类系统应该用于特定的临床场景。总之,对于糖尿病合并足溃疡患者,我们推荐:①医务人员之间的沟通:使用部位、缺血、神经病变、细菌感染、溃疡面积、溃疡深度(SINBAD)分类(第一选择)或考虑使用创面、缺血、足感染(WIfI)分类系统(替代选择,当具备所需的设备和专业水平,并且具有可行性时),针对每例患者,应具体描述组成分类系统的每个变量而不是仅仅报告总分;②不推荐任何现有分类系统用以预测特定个体的具体的溃疡结局;③对于描述有感染的溃疡患者的特征:使用美国感染性疾病学会(IDSA)/IWGDF(第一选择)分类或考虑使用WIfI系统(替代选择,当具备所需的设备和专业水平,并且具有可行性时);④对于描述周围动脉病变患者的特征:考虑使用WIfI系统作为对愈合可能性和截肢风险进行分层的手段;⑤对于人群结果的稽查:使用SINBAD评分。基于GRADE分级,本文提出的所有推荐,证据的可信度是低的。然而,基于对当前数据的合理应用,本文的推荐具有临床应用价值。

Sm-Nd年龄测定方法的新近应用,导致对许多太古宙变火成岩岩套已成功又合理地测定出火成岩结晶作用的精确时间。在火成岩处于亚固相蚀变和变质作用过程中,Sm和Nd似乎并未出现不稳定性状,而对这些岩石采用Rb-Sr法和Pb-Pb法测定年代往往是无效的。皮尔巴拉地块太古宙花岗岩-绿岩岩层的下部变质火山岩系(瓦拉沃纳 Warrawoona群)近来首次得出确实的年龄为34.52±16(2σ)Ma,它是由Pidgeon(1978)测定

BACKGROUND: Ultrasonography use is increasing in emergency departments, and ultrasound education is now recommended in resident training. Ultrasound phantoms are used in many institutions for training purposes. The purpose of this study is to describe an inexpensive and simple method to create ultrasound-imaging models for the purpose of education and practice using clear ballistic ***: Clear ballistic gel is used to simulate tissue for firing practice and other military ***: The transparent and durable ultrasound phantom we produced was clear and contained four vessel lumens. The images obtained using the phantom were of high quality and compared well to normal sonographic ***: The clear ballistic brand gel is unique because it is inexpensive, does not dry out, does not decay, is odorless, and is reusable. The ultrasound images obtained using the phantom are realistic and useful for ultrasound education.

High spin states in neutron-rich 110Ru nucleus have been investigated by measuring high-fold prompt γ-ray coincidence events of the spontaneous fission of 252Cf with the Gammasphere detector array. The ground-state band and the γ-vibrational band have been confirmed and extended with spin up to 18 and 13, respectively. The other three side bands, two proposed as two-quasiparticle bands and one proposed as a four-quasiparticle band, have been observed for the first time. The possible configurations for the quasi-particle bands are discussed. The cranked shell model calculations show that 110Ru nucleus may have oblate triaxial deformation with parameters β2 = -0.30 and γ = 24°, and the band crossing in the yrast band is due to the alignment of a pair of h11/2 neutrons.

The rotational bands up to a spin of 16 in the neutron-rich 106Mo nucleus have been investigated by measuring high-fold prompt γ-ray coincidence events following spontaneous fission of 252Cf with a Gammasphere detector array. The ground-state band, the one-phonon and two-phonon γ-vibrational bands, as well as a quasi-particle band have been confirmed and expanded. The other four collective rotational bands, three proposed as two-quasi-particle bands and one proposed as a β-vibrational band, have been newly observed. The characteristics of these collective bands and the possible configurations for the quasi-particle bands are discussed.
