1产妇月子行为和传统习惯及其影响因素显示文摘目的:探讨产妇月子传统习惯及其影响因素。方法:问卷调查与定性研究结合,对本市区产后42天左右的产妇776例问卷调查;定性研究采用半结构性访谈、关键人物访谈及专题小组讨论共调查63人次,其中半结构性访谈有产妇及其家人(丈夫、婆婆或母亲)36人,关键人物访谈有社区产后访视人员4人、中医4人,专题小组讨论有从事或负责社区产后访视工作的护理保健人员及中医19人。结果:776例产妇中,月子期间不洗头洗澡的有54.9%、不刷牙的有36.3%、不吃蔬菜的有19.3%、不吃水果的有36.1%,活动范围只能局限在居室内走动的为100%。主要是长辈的意愿及其传统观念起主导作用;产后访视次数对吃蔬菜的影响有显著性;产妇的文化程度和保健知识掌握程度与月子健康行为呈正相关。结论:从孕期、住院分娩、直至产后1个月内的家庭访视,要不断地向产妇及其婆婆、妈妈、丈夫等负责照顾产妇的家庭成员进行健康宣教,使保健知识不断得到强化,确立并形成产妇坐月子的健康行为,以利母婴身心健康。陈起燕 陈烈平 Joanna Raven 张荣莲 杨闽燕 2008中国妇幼保健2008,23,26:21
25-Azacytidine induces changes in electrophysiological properties of human mesenchymal stem cells显示文摘以前,导出髓的干细胞(MSC ) 与不确定的脱氧核糖核酸甲基转移酶禁止者 5-azacytidine 对待的老鼠骨头被报导区分 intocardiomyocytes。现在的学习的目的是在从健康骨髓施主获得的人的单音的原子房间调查类似的区别策略的效率。After1-3 段落,文化为 24 h 暴露于到 6 星期进一步的文化跟随的 5-azacytidine (3 mciroM ) 。药处理没导致 myogenic 标记 MyoD 或心脏的 markersNkx2.5 和 GATA-4 的表示并且没在后续期间产出跳动的房间。在补丁夹钳实验,近似 10-15% 对待,未经治疗的房间展出了 L 类型 Ca (2+) 水流。几乎所有房间表面地出现了修正快速或慢的激活动力学的 K (+) 水流。在与匹配时间的控制相比在 6 星期处理以后加倍的 +60 mV 意味着当前的振幅。对待的房间的 Membranecapacitance 比在在处理以后的 controls2 星期内显著地大并且在 6 个星期以后仍然保持高。为 K (+) 隧道 Kv1.1, Kv1.5, Kv2.1, Kv4.3 和 KCNMA1 并且为 Ca (2+) 隧道 Ca (v) 的 mRNAs 的表示层次 1.2 没被 5-azacytidine 影响。在以前显示出禁止 hMSC 的快速或慢慢地激活的 K (+) 水流的集中的 Treatmentwith 钾隧道块 ers tetraethylammonium 和 clofilium 禁止了这些房间的增长。我们的结果建议尽管有进 cardiomyocytes 的 hMSC 的区别的缺席,有 5-azacytidine 的处理在当前的密度引起了深刻变化。Bartosz Balanal Cecilia Nicoletti Ihor Zahanich Eva M Graf Torsten Christ Sabine Boxberger Ursula Ravens 2006Cell Research2006,16,12:20
3Maintaining biodiversity will define our long-term success显示文摘Human beings are not only a part of our planet's ecosystems,but also,they are massively overusing them.This makes ecosystem protection,including biodiversity preservation,vital for humanity's future.The speed and scale of the threat are unprecedented in human history.The long arch of evolution has been confronted with such a high level of human impact,that we are now facing the sixth mass extinction event,66 million years after the last one.This threat heightens the imperative for bold human intervention.Our paper identifies three strategies for such an intervention.First,and possibly most challenging,human demand needs to be curbed so it fits within the bounds of what Earth's ecosystems can renew.Without meeting this quantitative goal,biodiversity preservation efforts will not be able to get scaled.Second,in the transition time,we must focus on those locations and areas where most biodiversity is concentrated.Such a focus on‘hotspots’will help safeguard the largest portion of biodiversity with least effort.Third,to direct biodiversity preservation strategies,we need to much better document the existence and distribution of biodiversity around the globe.New information technologies could help with this critical effort.In conclusion,biodiversity preservation is no longer just a concern for specialized biologist but is becoming a societal necessity if humanity wants to have a stable future.Peter Raven Mathis Wackernagel 2020Plant Diversity2020,42,4:3

6Low serum neutralizing anti-SARS-CoV-2 S antibody levels in mildly affected COVID-19 convalescent patients revealed by two different detection methods显示文摘Neutralizing antibodies targeting the receptor-binding domain(RBD)of the SARS-CoV-2 spike(S)block severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)entry into cells via surface-expressed angiotensin-converting enzyme 2(ACE2).We used a surrogate virus neutralization test(sVNT)and SARS-CoV-2 S protein-pseudotyped vesicular stomatitis virus(VSV)vector-based neutralization assay(pVNT)to assess the degree to which serum antibodies from coronavirus disease 2019(COVID-19)convalescent patients interfere with the binding of SARS-CoV-2 S to ACE2.Both tests revealed neutralizing anti-SARS-CoV-2 S antibodies in the sera of ~90% of mildly and 100% of severely affected COVID-19 convalescent patients.Importantly,sVNT and pVNT results correlated strongly with each other and to the levels of anti-SARS-CoV-2 S1 IgG and IgA antibodies.Moreover,levels of neutralizing antibodies correlated with the duration and severity of clinical symptoms but not with patient age.Compared to pVNT,sVNT is less sophisticated and does not require any biosafety labs.Since this assay is also much faster and cheaper,sVNT will not only be important for evaluating the prevalence of neutralizing antibodies in a population but also for identifying promising plasma donors for successful passive antibody therapy.Berislav Bosnjak Saskia Catherina Stein Stefanie Willenzon Anne Katrin Cordes Wolfram Puppe Gunter Bernhardt Inga Ravens Christiane Ritter Christian R.Schultze-Florey Nina Godecke Jorg Martens Hannah Kleine-Weber Markus Hoffmann Anne Cossmann Mustafa Yilmaz Isabelle Pink Marius M.Hoeper Georg M.N.Behrens Stefan Pohlm ann Rainer Blasczyk Thomas F.Schulz Reinhold Forster 2021Cellular & Molecular Immunology2021,18,4:2
