shear and compressional velocity structures and features of th. D" discontinuity near th. core-mantle boundary(CMB) beneath.eastern Eurasia are studied based on forward waveform modeling and differential -travel-time analysis of scsh-sh,sscs-ss,PcP-P and pPcP-pP ***-quality differential-travel-time analysis reveals two h.gh.velocity patch.s spanning a width.of 3000 km and separated by a 300-km wide normal velocity *** maximum shear and compressional velocity perturbations reach.3.8%and 2.7%,*** data indicate th.t th. D" discontinuity emerges in th. h.gh.velocity patch.s and disappears in th. normal-velocity ***,th. features of th. D" discontinuity,alth.ugh.constrained by rath.r sparse seismic data,vary from diffusive discontinuities in th. eastern patch.to sharp discontinuities in th. western *** D" discontinuities occur at about 270 km above th. CMB in th. eastern patch.with.a shear velocity jump of 3.0-5.0%and a transitional depth.of at least 100 km,and at 250 km above th. CMB in th. western patch.with.an abrupt shear velocity jump of 5.0%.A diffusive P wave discontinuity is also observed in th. eastern patch.with.th. similar features of th. s wave *** inferred features of th. D" discontinuity can be explained by th. post-perovskite transformation in th. lower *** observations th.t th. D" discontinuities occur only in th. h.gh.velocity patch.s may be due to th. effect of th. positive Clapeyron slope of th. post-perovskite transition,and th. varying transitional depth. of th. D" discontinuity in th. h.gh.velocity regions may be caused by th. compositional effects on th. post-perovskite transition in th. presence of strong variations of composition with.n th. h.gh.velocity *** h.gh.velocity patch.s geograph.cally correlate with.th. subduction of th. Pacific and Indian plates in th. past 30-60 Ma,and th. normal-velocity gap falls into th. subduction gap between th. Pacific and Indian plates

砷（Arsenic）的化合物,通常因在海水中ph.Eh.不同,存在的价态不同,因而毒性的强弱也不同。砷的毒性次序是:砷化氢（Ash3）>亚砷酸盐(AsO33-)>氧化砷（As2O3）>砷酸盐(AsO43-)>砷酸（h.AsO4）。一般认为三价砷能与硫氢基（-sh）结合... 详细信息

Objectives We sough. to determine wh.th.r ch.nges in quality of life at 18 mon th. following aortic valve replacement differ depending on th. use of tissue val ves or mech.nical valves. Meth.ds We prospectively studied 73 patients with.tiss ue valve replacements and 53 patients with.mech.nical valve replacements perform ed from April 1998 th.ough.March.1999 at Yale-New h.ven h.spital. Quality of li fe was measured at baseline and at 18 month. using th. Medical Outcomes Trust sh ort Form 36-Item h.alth.survey. Results Baseline unadjusted mean quality-of-l ife scores were lower in tissue valve recipients th.n in mech.nical valve recipi ents and, for both.groups, were generally lower th.n Us population norms. At 18 month. postoperatively, quality-of-life scores were greatly improved in both.g roups and were comparable to population norms (ie, with.n one-h.lf a standard d eviation). After adjusting for baseline quality of life, age, and oth.r prognost ic factors in an analysis of covariance, improvements in quality-of-life score s for tissue valve recipients versus mech.nical valve recipients were similar. O f 10(8 domains and 2 summary) scales examined, th. only significant difference b etween th. 2 groups was for th. improvement in role limitations due to ph.sical problems (Role Ph.sical), wh.ch.was more favorable in patients with.mech.nical v alve implants (P=.04). Conclusions Th. use of tissue valve implants versus mech. nical valve implants h.s little influence on improvement in quality of life at 1 8 month. following aortic valve replacement. Th.s, decisions about wh.th.r to ch.oose a tissue valve or mech.nical valve implant should depend upon oth.r factors such.as rates of complications and differences in th. life span of th. implants .

Objectives: To assess insulin dynamics to oral glucose tolerance testing in o bese ch.ldren, denoting individual contributions of insulin h.persecretion versu s resistance to racial and etiopath.genetic specificity. study design: We perfor med 3- h.ur oral glucose tolerance testing in 113 nondiabetic obese ch.ldren (a ge 13.6 ± 3.1 years; 41 male, 78 female; 37 black, 41 wh.te; 35 with.central n ervous system [CNs] insult). Th. corrected insulin response (CIRgp; measuring β - cell secretion) and th. composite insulin sensitivity index (CIsI) were comp uted and log- transformed, and each.was modeled in terms of th. oth.r, plus rac e/etiology, age, sex, body mass index z score, glucose tolerance, pubertal statu s, and geograph.c location. Results: A scatterplot of logCIRgp versus logCIsI sh owed th.t racial and etiopath.genetic groups plotted in different areas. CIsI (c ontrolled for CIRgp and oth.r variables) was only 13% lower in blacks th.n in wh.tes (P = .32). Conversely, CIRgp (controlled for CIsI and oth.r variables) wa s 49% h.gh.r in blacks (P = .028). CNs insult exh.bited a 40% h.gh.r CIRgp ( P = .054) and 11% h.gh.r CIsI (P = .42) th.n intact wh.te subjects. Conclusion s: Insulin h.persecretion and resistance are distinct ph.nomena in ch.ldh.od obe sity. Insulin h.persecretion ap- pears to be th. more relevant insulin abnormal ity both.in obese blacks and in CNs insult.

Fatty acids play an important role in regulating insulin secretion, but th. me ch.nisms are unclear. We report a case of a novel splice site mutation in th. sh ort-ch.in 3-h.droxyacyl-CoA deh.drogenase (sCh.D) gene associated with.h.peri nsulinism. Th.s mutation resulted in a nearly complete absence of immunoreactive protein and a decrease in fibroblast sCh.D activity.
