SULTRY weather and the swaying of the train made Edouard Tourville’s head droop. His wife,Marie-Anne, dozed beside him. The tiny, gentle-voiced woman had seldom left the village during her more than sixty years there. When their Spartan existence on the small farm drove their only son, Paul, to the city, Marie-Anne (ounted the months like beads on her rosary for his return. But Paul had joined the Air Force and married just before the terrible flying accident that took his life. Because his attractive wire was on orphan, the Tourvilles brought her to live

A model of a fissioning nucleus that splits symmetrically both axially and equatorially is used to show how one can predict the presence of a fission barrier of several tens of MeV for nuclides of mass number A ~ 90 and of ~ 10 MeV for elements such as uranium. While the present model sacrifices some physical realism for the sake of analytic and programming simplicity, it does reproduce the general behavior of the run of fission barrier energy as a function of mass number as revealed by much more sophisticated models. Its intuitive appeal and tractability make it appropriate for presentation in a student-level “Modern Physics” class.

英国阿伯丁大学院院长R·cameron教授于1992年4月访中山大学,期间作了“理解因果性”、“行动的本性”、“当代西方哲学中的身心”三个学术报告。后一报告对特殊途径概念的强调、对心脑等同论的反驳、关于计算机不能思维以及意识相对于行为是多余的这些观点的阐述,引起听众的浓厚兴趣并提出了许多问题进行讨论。本文根据讲演稿译出,由于篇幅有限,译文有较大的删节,小标题作了相应的调整。

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is commonly used for refractory cardiac or respiratory failure. There are reported cases of successful use of ECMO in patients with septic shock;however, there is a lack of evidence to prove its overall efficacy. Thus, we conducted this study to analyze the relationship between sepsis and ECMO in our own patients. METHODS: 305 patients who were placed on ECMO between 2010 and 2020 were identified within an IRB-approved database. Their clinical outcomes were analyzed with a specific focus on patients who were septic before or during ECMO, defined as a positive blood culture. Group S was composed of patients with a positive blood culture before or during ECMO, while Group N was composed of all patients without a positive blood culture before or during ECMO. The primary outcome compared between groups was ECMO survival rate. RESULTS: Among the 305 patients on ECMO, 58 (19%) were in Group S and 247 (81%) were in Group N. ECMO survival rates were 45% in Group S and 62% in Group N (p = 0.017). CONCLUSION

Recommendations for probiotics are available in several regions. This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects,health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745(Sb) and Lactobacillus rhamnosus GG(LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of(with the indicated strains): antibiotic-associated diarrhea(LGG or Sb); Clostridium difficile-induced diarrhea(Sb); nosocomial diarrhea(LGG); infantile colic(L reuteri) and as adjunct treatment of Helicobacter pylori(Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological,socioeconomical and health system conditions,similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials.

Background Rev is necessary for exporting unspliced and incompletely spliced intron containing HIV mRNAs and for HIV replication. The aim of this study is to develop a kind of selective suicide construct that can specifically and directly induce HIV infected cells into apoptosis based on the high affinity of Rev and Rev response element （RRE）. Methods Molecular-cloning technique was used to synthesis Rev dependent TNF-R1 expression construct pDM128-TNF-R1 （pT128） that contains RRE and TNFR1 gene. Restriction digestion, Polymerase Chain Reaction （PCR） and DNA sequencing were processed and the exactness and correctness of the inserted TNF-R1 gene in pT128 were confirmed repeatedly. The expression of pT128 co-transfected with different combination of other plasmids by calcium phosphate-DNA co-precipitation in Helas and by gene gun transfection in keratinocytes was further tested by flow-cytometry and cell counted under microscope. Results The new plasmid specifically expressed TNF-R1 in Helas when co-transfected with pRev but did not when without pRev. Indirect expression of TNF-R1 from pT128 was slower than the direct expression of that from Hu p60 TNFR1 in pDC302 （pT60） , but all those pT60 or pT128 transfected cells showed apoptosis at last while TNF-R1 was sufficiently expressed. Other kinds of Rev expression construct such as pAD8 and a chimeric HIV vaccine also can switched on the selective expression of pT128. Not only Rev-dependent expression in Helas, pT128 also normally expressed its TNF-R1 in keratinocytes. Co-transfected with prey or pAD8 that expressed Rev, pT128 expressed TNF-R1 and induced apoptosis of green fluorescent keratinocytes in skin explant. The number of green fluorescent keratinocytes co-transfected by pT128 plus prey or pAD8 was gradually outnumbered by that co-transfected by pT128 only. The difference was more significant after culturing for 72 hours. Conclusions Rev dependent pT128 is able to selectively induce apoptosis of HIV-infect
