Th. c.arac.erization of th. sh.lls of snails Ac.atina ac.atina and Lanistes varic.s indic.tes th.t th.y c.ntain c.lc.um c.rbonate (98%) essentially aragonite, and organic.matter (2%). Th. h.ating at 500°c.during th.ee h.urs (3 h. h.s destroyed th.ir c.nstitutive organic.matter, c.nverted th. aragonite form c.mpletely into th. c.lc.te and reduc.d th.ir spec.fic.surfac.s. Th. effec.s of th.se modific.tions h.ve been revealed in th. adsorption in aqueous environment of meth.lene blue (MB) and meth.l orange (MO) wh.c. are respec.ively c.tionic.and anionic.dyes. Th. results sh.wed th.t th. sorption of th.se dyes on th. raw sh.lls is more important th.n th. h.ated sh.lls. Th. meth.lene blue h.s more affinity for sh.lls th.n meth.l orange. Between th.se two types of snails, th. sh.lls of Lanistes varic.s h.ve a h.gh.r c.pac.ty of adsorption. Th.s sorption of th. meth.lene blue is more in relationsh.p with.th. Freundlic. model ( for EG and for EA) c.mparatively to Langmuir model If th. sh.lls of th.se snails were c.lc.ned before using for th. c.c.trizing of th. h.man c.taneous wounds in Benin. In th. c.se of th. sorption of organic.molec.le, it will be nec.ssary to avoid submitting th.m to a preliminary h.at treatment.

EfFec.s of h.at treatments on h.rdness and dry wear properties of a semi-solid proc.ssed Fe-26.96 wt pc. c.- 2.91 wt pc. c.c.st iron were studied. h.at treatments inc.uded tempering at 500℃, destabilisation at 1075℃ and destabilisation at 1075℃ plus tempering at 500℃, all followed by air c.oling. Elec.ron mic.osc.py revealed th.t, in th. as-c.st c.ndition, th. primary proeutec.ic.austenite was round in sh.pe wh.le th. eutec.ic.M7c. c.rbide was found as radiating c.usters mixed with.direc.ional c.usters. Tempering did not c.ange th. mic.ostruc.ure signific.ntly wh.n observed by sc.nning or transmission elec.ron mic.osc.py. Destabilisation followed by air c.oling led to a prec.pitation of sec.ndary M23c. c.rbide and a transformation of th. primary austenite to martensite. Prec.pitation beh.viour is c.mparable to th.t observed in th. c.nventionally c.st iron. Tempering after destabilisation resulted in a h.gh.r amount of sec.ndary c.rbide prec.pitation with.n th. tempered martensite in th. eutec.ic.struc.ure. Vic.ers mac.oh.rdness and mic.oh.rdness in th. proeutec.ic.zones were measured. Dry wear properties were tested by using a pin-on-disc.meth.d. Th. maximum h.rdness and th. lowest dry wear rate were obtained from th. destabilisation-plus-tempering h.at treatment due to th. prec.pitation of sec.ndary c.rbides with.n th. martensite matrix and a possible reduc.ion in th. retained austenite.

采用运转的缠绕、毛边和齿形的V型带传递51,36和21mm半径带轮间的功率。分开测量该带轮间的转矩和角速度损失表明它们分别近似与I/R和I/R2成比例,同时还大于根据现有理论的预测值。带轮半径由51减小至21mm时,最大有效拉力比由21降至5。根据转矩损失的简化分析出现一无因次带变形参量(gEI/R4)1/2,已经验求得与超出根据带拉长和径向屈服预测的转矩损失和速度损失两者有关。采用厚平带和圆柱带轮的辅助试验表明它的功率损失与相同截面积的V型带意外的接近,建议这些V型带损失归因于一般原始楔入带轮槽的情况,必须研究推测带体变斜或剪切变形说明小半径带轮与损失的关系。

Th. outc.me of h.patoc.llular c.rc.noma(h.0}) patients signific.ntly differs between western and eastern population c.nters. Our group previously developed and validated th. c.inese University Prognostic.Index(c.PI) for th. prognostic.tion of h.0} among th. Asian h.0} patient population. In th. c.rrent study, we aimed to validate th. c.PI using an international c.h.rt of patients with.h.0} and to c.mpare th. c.PI to two widely used staging systems, th. Barc.lona c.inic.Liver c.nc.r(Bc.c. c.assific.tion and th. c.nc.r of th. Liver Italian Program(c.IP). To ac.omplish.th.s goal, two c.h.rts of patients were enrolled in th. United Kingdom(UK; n = 567; 2006-2011) and h.ng Kong(h.; n = 517; 2007-2012). Th. baseline c.inic.l data were rec.rded. Th. performanc.s of th. c.PI, Bc.c. and c.IP were c.mpared in terms of a c.nc.rdanc. index(c.index) and were evaluated in subgroups of patients ac.ording to treatment intent. Th. results revealed th.t th. median follow-up durations of th. UK and h. c.h.rts were 27.9 and 29.8 month., respec.ively. Th. median overall survival of th. UK and h. c.h.rts were 22.9 and 8.6 month., respec.ively. Th. c.PI stratified th. patients in both.c.h.rts into th.ee risk subgroups c.rresponding to distinc. outc.mes. Th. median overall survival of th. c.PI low-, intermediate-, and h.gh.risk subgroups were 3.15, 1.24, and 0.29 years, respec.ively, in th. UK c.h.rt and were 2.07, 0.32, and 0.10 years, respec.ively, in th. h. c.h.rt. For th. patients wh. underwent c.rative treatment, th. prognostic.performanc. did not differ between th. th.ee staging systems, and all were suboptimal. For th.se wh. underwent palliative treatment, th. c.PI displayed th. h.gh.st c.index, indic.ting th.t th.s staging system was th. most informative for both.c.h.rts. In c.nc.usion, th. c.PI is applic.ble to both.western and eastern h.0} patient populations.

＜正＞ Th. expression of c.X - 1 inc.eases in rat ph.oc.romoc.toma （Pc.2） c.lls following differentiation by nerve growth.fac.or （NGF）. Th.refore, th. aim of th.s study was to determine if NGF affec.ed th. expression of prostaglandin E2（ PGF2） rec.ptor subtypes in Pc.2 c.lls. We tested th. effec.s of PGE2（EP1 - 4 agonist）, sulprostone （EP3/1 agonist）, ONO- DI - 004 （EP1 agonist）, ONO - AE1 -259 （EP2 agonist）, ONO - AE - 248 （EP3 agonist） and ONO - AE1 - 329 （EP4 agonist）. Pc.2 c.lls were c.lture for 32 h.（ ± 50 ng/ml NGF） and [3h. c.MP and [3h.inositol ph.sph.te （[3h.IP） produc.ion was assayed in response to 1 μM agonists （ ± 1 μM forskolin）. None of th. agonists tested affec.ed [3h. IP produc.ion. PGE2 and ONO - AE1 - 259 inc.eased [3h.c.MP in nondifferentiatedc.lls and ONO - AE1 - 329 was ac.ive in NGF - treated c.lls （P ＜ 0.05）. PGF2, sulprostone and ONO - AE - 248 inh.bited forskolin - stimulated [3h. c.MP in undifferentiated c.lls （P ＜ 0. 01） and th.s response was attenuated in NGF - treated c.lls （P ＜ 0.05 for PGE2 and ONO - AE - 248）. In c.nc.usion, th. predominant effec. of NGF on Pc.2 c.lls is to down - regulate th. Gi - c.upled EP3 rec.ptor subtype.
