金融发展研究 2016年第4期 31-33页

作者：珍妮特.耶伦王宇中国人民银行研究局

美国国内经济虽然存在波动,但仍然比较稳固。但全球经济和金融市场的不确定性增加令美国经济面临的风险增加,美联储应结合经济数据,审慎地进行加息。美联储可能会在必要时实施"非常规政策",引导长期利率下行。

目的脑卒中后抑郁状态是常见的精神卫生问题,应引起临床医护人员的关注。本文旨在探讨影响首次卒中患者出现卒中后抑郁的相关因素。方法采用6个月纵向研究设计,共选定两个观察时间点:T1,入住康复病房后的48h内;T2,相距T1后的第6个月。数据收集均于受试者当时的居住地进行。纳入居住在香港特别行政区首次患脑中卒的患者(除外伴有意识障碍或失语症)。结果T1和T2时卒中后抑郁的发生率分别为69%和48%。向后线性回归分析发现,共有5个变量可解释T2时卒中后抑郁55%的差异。其相关因素包括:在T1时抑郁症状的水平(P<0.001)、患者社会角色在病前为居家主妇(P=0.039)、在T2时的功能残疾水平(P<0.001)、获得的信息支持(P=0.025)及朋辈间的交谊支持(P=0.001)。结论本研究的结果表明,卒中后抑郁可以是因卒中致残及家庭角色改变而出现的一种精神卫生问题。心理及社会支持是照顾护理脑卒中患者时不可或缺的一部份。

In vitro eval.ation of a new resil.ent, hard-carbon, thin-fil. coating as a bearing material.for ventricul.r assist devices ——In Vitro Bearing Eval.ation of BioMedFl.x

引用

Journal.of Biomedical.Science and Engineering 2010年第5期3卷 525-528页

作者： Nicol. A. Miel.e Al.x l. Massiel.o David J. Horvath Stephen M. Benefit Darren Burgess leonard A. R. Gol.ing Kiyotaka Fukamachi 不详

Our aim was to eval.ate the potential.use of BioMedFl.x? (BMF), a new resil.ent, hard-carbon, thin- fil. coating, as a bl.od journal.bearing material.in Cl.vel.nd Heart’s continuous-fl.w l.ft and right ven- tricul.r assist devices (VADs). BMF is not cl.ssified as a diamond-l.ke carbon (Dl.) and differs from other thin-fil. carbon coatings by its high fl.xural.strength, radiopacity, and wear resistance. A 2- to 4-μm-thick BMF adhesion l.yer was deposited on the VAD journal.bearing surfaces. A commercial.Dl. coating used in other cl.nical.bl.od pump appl.cations was used as a control. Durabil.ty and rel.abil.ty of the BMF coating was verified in severe pump start/stop testing using 20 BMF-coated journal.bearing pairs. The BMF-coated surfaces showed no coating fail.res, whereas 57% of the Dl. bearing pairs devel.ped scratches through the carbon coating, documenting that BMF can provide a durabl. coating in our bl.od journal.bearing appl.cation. In concl.sion, BMF has shown qual.ties that support its significant advantages as an al.ernative journal.bea- ring material.in Cl.vel.nd Heart pumps. Our pl.n incl.des biocompatibil.ty testing with ongoing animal.studies, endurance testing with submerged pumps running in sal.ne, and assessment of batch coating processing capabil.ty.

Transformation Semigroup of Al.ernating Nonnegative Integers

引用

Advances in Pure Mathematics 2022年第11期12卷 614-623页

作者： Adenike Ol.sol. Adeniji janet Ifiok Obafemi Department of Mathematics Faculty of Science University of Abuja Abuja Nigeria

Set of integers, Zn is spl.t into even-odd parts. The even part is arranged in ways, whil. the odd part fixes one point at a time to compl.ment the even part thereby forming the semigroup, AZn. Thus, -spaces are fil.ed choosing maximum of two even points at a time. Green’s rel.tions have formed important structures that enhance the al.ebraic study of transformation semigroups. The semigroup of Al.ernating Nonnegative Integers for n-even (AZn-even) is shown to have onl. two D-cl.sses, and there are -cl.sses for n≥4. The cardinal.ty of l.cl.sses is constant. Certain cardinal.ties and some other properties were derived. The coefficients of the zigzag tripl.s obtained are 1, and . The second and third coefficients can be obtained by zigzag addition.

阿育吠陀被认为是世界上最古老的医学体系之一,在这个神奇又神秘的医学体系中,还有许多智慧未被挖掘出来。世界上存在着许多种传统医学体系,不同传统医学体系的交融可为草药医学的发展带来新的契机。而目前,人们缺乏对传统医学体系间相似性和差异性的理解,导致融合出现障碍。拟阐述阿育吠陀医学的古老历史和基本准则,以期帮助学者、研究人员和行医者更加深刻地了解传统医学体系,进而使阿育吠陀医学与其他传统医学体系之间求同存异,克服障碍,获得全球的认可和相互和谐共存。

Al.el.pathic Potential. of Some Crop Residues on the Germination and Seedl.ng Growth of Chromol.ena Odoratum l.

作者： Modupe janet Ayeni Joshua Kayode Department of Pl.nt Science University of Ado-Ekiti Ado-Ekiti 361010 Nigeria

The al.el.pathic effects of aqueous extracts of rice husk （Orza sativa l.） and sorghum stem （Sorghum bicol.r l.） on the germination and seedl.ng growth of Chromol.ena odoratum l. were investigated. The extracts of the two crop residues exhibited inhibitory effects on the germination and seedl.ng growth of Chromol.ena odoratum l. The degree of retardation demonstrated in both extracts was concentration dependent. However the resul.s obtained reveal.d that the retardation was more pronounced in the rice husk extract-treated seeds. However statistical.anal.sis （P 〈 0.05% l.vel. reveal.d that the degrees of inhibition of radicl. and pl.mul. obtained from various extracts treated seeds of both extracts were not significantl. different when compared to those obtained from the control.experiments as wel. as those obtained from the varying extract concentrations.

Treg cel.s in pancreatic l.mph nodes： the possibl. rol. in diabetogenesis and βcel. regeneration in a TID model

引用

Cel.ul.r & Mol.cul.r Immunol.gy 2012年第6期9卷 455-463页

作者： Benjamin K Nti janet l.Markman Suzanne Bertera Al.xis J Styche Robert J l.komy Vl.dimir M Subbotin Massimo Trucco Tatiana D Zorina Indiana University School.of Medicine Indianapolis IN USA Cedars-Sinai Medical.Center Los Angeles CA USA Division of Irnmunogenetics Children's Hospital of Pittsburgh University of Pittsburgh School of Medicine Pittsburgh PA USA Independent investigator 602 Samuel.Dr. Madison Wl USA Department of Bioscience Technol.gies Jefferson School of Health Professions Thomas Jefferson University Philadelphia PA USA

Previousl., we establ.shed a model.in which physiol.gical.y adequate function of the autol.gous β cel.s was recovered in non-obese diabetic （NOD） mice after the onset of hypergl.cemia by rendering them hemopoietic chimera. These mice were termed antea-diabetic. In the current study, we addressed the rol. of T regul.tory （Treg） cel.s in the mechanisms mediating the restoration of eugl.cemia in the antea-diabetic NOD model. The data generated in this study demonstrated that the numbers of Treg cel.s were decreased in unmanipul.ted NOD mice, with the most profound deficiency detected in the pancreatic l.mph nodes （Pl.s）. The impaired retention of the Treg cel.s in the Pl.s correl.ted with the l.cal.y compromised profil. of the chemokines invol.ed in their trafficking, with the most prominent decrease observed in SDF-1. The amel.oration of autoimmunity and restoration of eugl.cemia observed in the antea-diabetic mice was associated with restoration of the Treg cel. popul.tion in the Pl.s. These data indicate that the function of the SDF-1/CXCR4 axis and the retention of Treg cel.s in the Pl.s have a potential.rol. in diabetogenesis and in the amel.oration of autoimmunity and β cel. regeneration in the antea-diabetic model. We have demonstrated in the antea-diabetic mouse model.that l.fel.ng recovery of the β cel.s has a strong correl.tion with normal.zation of the Treg cel. popul.tion in the Pl.s. This finding offers new opportunities for testing the immunomodul.tory regimens that promote accumul.tion of Treg cel.s in the Pl.s as a therapeutic approach for type 1 diabetes （TID）.
