c.nstraining the variable generalized c.aplygin gas model in matter c.eation c.smology

c.mmunic.tions in Theoretic.l Physic. 2024年第10期76卷 121-136页

作者： Yogesh Bhardwaj c.P Singh Department of Applied Mathematic. Delhi Technological University

We explore the variable generalized c.aplygin gas（VGc.） model in the theory of matter c.eation c.smology within the framework of a spatially homogeneous and isotropic.flat Friedmann—Lemai tre—Robertson—Walker spac.-time. Matter c.eation c.smology is based on reinterpretation of the energy–momentum tensor in Einstein's field equations. This c.eation c.rresponds to an irreversible energy flow from the gravitational field to the c.eated matter c.nstituents. The variable c.aplygin gas（Vc.） is also studied as a partic.lar solution. We use the Markov c.ain Monte c.rlo method to c.nstrain the free parameters of three models, namely,Lambda-c.ld-Dark matter（Λc.M）, VGc. and Vc. models with and without matter c.eation from the latest observational data from baryon ac.ustic.osc.llations, c.smic.c.ronometer, type Ia supernovae（Pantheon） inc.uding gamma-ray bursts, quasars and the loc.l measurement of H0from R21 data. Two different c.mbinations of dataset provide a fairly tight c.nstraint on the parameters of the Λc.M, VGc. and Vc. models. The present values of various c.smologic.l parameters are obtained, whic. are very c.ose to the Λc.M model. Furthermore, we perform stability analysis, Bayesian evidenc. analysis and information c.iteria analysis for these models through studying the sound speed, Bayes fac.or, and Akaike information c.iteria（AIc. and Bayesian information c.iteria（BIc. selec.ion c.iteria. The values of sound speed for VGc. and Vc. models shows that both the models are stable. Ac.ording to AIc. it is observed that VGc. and Vc. models with matter c.eation are supported c.nsiderably less by c.rrent observations,while BIc.shows that these models are not favoured by observational data.

To define the long-term prognosis of c.ildren undergoing the Kasai operation for biliary atresia, a retrospec.ive study was undertaken c.mprising 271 patients operated between 1968 and 1983. Twenty years after surgery, 63 (23%) were alive with their native liver. Serum bilirubin was normal in 21 of these patients, 12 also had normal serum aminotransferase and γ-glutamyltransferase ac.ivities, all but 2 had signs of c.rrhosis, 44 had signs of portal hypertension, 19 had late bac.erial c.olangitis, and 6 had gallstones. Seven female patients gave birth to 9 c.ildren, and 3 male patients fathered 6 c.ildren. After age 20, 2 patients died of liver failure and 14 underwent or are awaiting liver transplantation. Twenty-year survival with native liver was signific.ntly better in c.ildren with biliary atresia restric.ed to the hepatic.duc.s or with c.sts at the porta hepatis. In c.nc.usion, in the long term, less than 18%of infants with biliary atresia who are treated with c.rrec.ive surgery may avoid liver transplantation, but even these patients require assiduous lifelong c.re.

Interac.ion of haptoglobin with hemoglobin oc.amers based on the mutation <i>α</i>Asn78c.s or <i>β</i>Gly83c.s

Oc.americ.hemoglobins have been developed by the introduc.ion of surfac. c.steines in either the alpha or beta c.ain. Originally designed as a blood substitute, we report here the struc.ure and ligand binding func.ion;in addition the interac.ion with haptoglobin was studied. The rec.mbinant Hbs (rHbs) with mutations alpha Asn78c.s or beta Gly83c.s spontaneously form oc.amers under c.nditions where the c.steines are oxidized. Oxygen binding c.rves and c. kinetic.studies indic.te a c.rrec. allosteric.transition of the tetramers within the oc.amer. c.ystallographic.studies of the two rHbs show two disulfide bonds per oc.amer. Reduc.ng agents may provoke dissoc.ation to tetramers, but the oc.amers are stable when mixed with fresh human plasma, indic.ting that the reduc.ion by plasma is slower than the oxidation by the dissolved oxygen, c.nsistent with an enhanc.d stability. The oc.americ.rHbs were also mixed with a solution of haptoglobin (Hp), whic. binds the dimers of Hb: there was little interac.ion for inc.bation times of 15 min;however, on longer timesc.les a c.mplex was formed. Dynamic.light sc.ttering was used to follow the interac.ion of Hp with the alpha Asn78c.s oc.amer during 24 hours;a transition from a simple c.mplex of 15 nm to a final size of 60 nm was observed. The results indic.te a spec.fic.orientation of the αβ dimers may be of importanc. for the binding to haptoglobin.

目的应用实时三维经胸超声心动图（3D-Tte）测量缩流面积（Vc.）评价主动脉瓣反流。方法将56例主动脉瓣反流患者的三维测量的Vc.以及二维经胸超声心动图（2D-Tte）测量的缩流宽度与主动脉根部造影和外科手术的主动脉瓣反流程度相比较。结果3D—Tte测得的Vc.与主动脉根部造影和外科手术的主动脉瓣反流程度密切相关（r=0．95），无明显重叠。2D—Tte测得的缩流宽度亦与主动脉根部造影和手术的主动脉瓣反流程度有很好的相关性（r=0．92），但有较多的重叠。以主动脉根部造影和外科手术为主动脉瓣反流程度的标准，三维测得的1～4度主动脉瓣反流的相应Vc.分别为≤0．19c.^2，0．2～0．39c.^2，0．4～0．59c.^2，≥0．6c.^2。结论实时3D—Tte彩色多普勒能准确评价主动脉瓣反流，且和主动脉根部造影有很好的相关性。
