在６８０ ℃和５００ＭＰａ以及岩石学相平衡条件下，首次对方解石与镁橄榄石之间在大量超临界ＣＯ２Ｈ２Ｏ流体存在的条件下进行了氧同位素交换实验。结果发现，在实验刚刚开始的一段时间内氧同位素交换很快，主要是以溶解／重结晶的机制进行的；而在以后的时间里氧同位素交换要慢得多，变成以扩散机制为主。进一步，反应产物方解石相对于镁橄榄石亏损１８Ｏ，指示方解石的溶解／重结晶速率大于镁橄榄石。流体相的存在导致具不同溶解／重结晶速率的矿物与流体之间的氧同位素交换速率不同，结果使矿物矿物或矿物流体体系的氧同位素分馏在实验过程中不是单向地朝着平衡值方向移动，而是简单地超越平衡值，甚至出现“倒转”现象。只是当体系达到化学平衡后，溶解／重结晶作用显著减慢或停止，扩散作用才成为驱动体系朝向同位素平衡的主要机制。这时，方解石中氧的扩散速率等于或略大于镁橄榄石。因此，在应用实验测定的矿物氧扩散速率计算水岩反应的时间尺度时，必须首先排除溶解／重结晶和矿物蚀变引起的同位素交换。

Background & Aim.: Colonoscopic polypectom. is considered effective for preventing colorectal cancer (CRC), but the incidence of cancer in patients under colonoscopic surveillance has rarely been investigated. We determ.ned the incidence of CRC in patients under colonoscopic surveillance and exam.ned the circum.tances and risk factors for CRC and adenom. with high- grade dysplasia. m.thods: Patients were drawn from.3 adenom. chem.prevention trials. All underwent baseline colonoscopy with rem.val of at least one adenom. and were deem.d free of rem.ining lesions. We identified patients subsequently diagnosed with invasive cancer or adenom. with high- grade dysplasia. The tim.ng, location, and outcom. of all cases of cancer and high- grade dysplasia identified are described and risks associated with their developm.nt explored. Results: CRC was diagnosed in 19 of the 2915 patients over a m.an follow- up of 3.7 years (incidence, 1.74 cancers/1000 person- years). The cancers were located in all regions of the colon; 10 were at or proxim.l to the hepatic flexure. Although m.st of the cancers (84% ) were of early stage, 2 participants died of CRC. Seven patients were diagnosed with adenom. with high- grade dysplasia during follow- up. Older patients and those with a history of m.re adenom.s were at higher risk of being diagnosed with invasive cancer or adenom. with high- grade dysplasia. Conclusions: CRC is diagnosed in a clinically im.ortant proportion of patients following com.lete colonoscopy and polypectom.. m.re precise and representative estim.tes of CRC incidence and death am.ng patients undergoing surveillance exam.nations are needed.

The physics of com.ressible turbulence in high energy density(HEd) plasm.s is an unchartered experim.ntal *** of com.ressible and radiative flows relevant for astrophysics rely m.inly on subscale param.ters. Therefore,we plan to perform.turbulent hydrodynam.cs experim.nts in HEd plasm.s(TurboHEdP) in order to im.rove our understanding of such im.ortant phenom.na for interest in both com.unities: laser plasm. physics and astrophysics. We will focus on the physics of supernovae rem.ants which are com.lex structures subject to fluid instabilities such as the Rayleigh–Taylor and Kelvin–Helm.oltz instabilities. The advent of m.gajoule laser facilities, like the National Ignition Facility and the Laser m.gajoule, creates novel opportunities in laboratory astrophysics, as it provides unique platform. to study turbulent m.xing flows in HEd plasm.s. Indeed, the physics requires accelerating targets over larger distances and longer tim. periods than previously achieved. In a preparatory phase, scaling from.experim.nts at lower laser energies is used to guarantee the perform.nce of future m. experim.nts. This subscale experim.nts allow us to develop experim.ntal skills and num.rical tools in this new field of research, and are stepping stones to achieve our objectives on larger laser facilities. We review first in this paper recent advances in high energy density experim.nts devoted to laboratory astrophysics. Then we describe the necessary steps forward to com.ission an experim.ntal platform.devoted to turbulent hydrodynam.cs on a m.gajoule laser facility. Recent novel experim.ntal results acquired on LULI2000, as well as supporting radiative hydrodynam.cs sim.lations, are presented. Together with the developm.nt of LiF detectors as transform.tive X-ray diagnostics, these prelim.nary results are prom.sing on the way to achieve m.crom.tric spatial resolution in turbulent HEd physics experim.nts in the near future.

AIm. Standard im.unosuppression after organ transplantation stim.lates tum.r growth. Sirolim.s has a strong antiproliferative and a tum.r inhibiting effect. The purpose is to assess the effect on tum.r growth of the im.unosuppressive com.ounds sirolim.s and tacrolim.s alone and in com.ination on cells of hum.n hepatocellular ***: We used the hum.n cell lines SK-Hep 1 and Hep 3B derived from.hepatocellular carcinom.. Proliferation analyses after treatm.nt with sirolim.s, tacrolim.s, or the com.ination of both were perform.d. FACS analyses were done to reveal cell cycle changes and apoptotic cell death. The expression of apoptosis-related proteins was estim.ted by Western ***: Sirolim.s alone or com.ined with tacrolim.s inhibited the growth of both cell lines after 5 d by up to 35% in SK-Hep 1 cells, and by up to 68% in Hep 3B cells at 25 ng/m.. Tacrolim.s alone stim.lated the growth by 12% after 5 ng/m. and by 25% after 25 ng/m. in Hep 3B cells. We found an increase of apoptotic Hep 3B cells from.6 to 16%, and a G1-arrest in SK-Hep 1 cells with an increase of cells from.61 to 82%, when sirolim.s and tacrolim.s were com.ined. Bcl-2 was down-regulated in Hep 3B, but not in SK-Hep 1 cells after com.ined ***: Sirolim.s appears to inhibit the growth of hepatocellular carcinom. cells alone and in com.ination with tacrolim.s. Sirolim.s seem. to inhibit the growth stim.lation of tacrolim.s.

Aim. To com.are 90°, 180°, and 360°selective laser trabeculoplasty (SLT, 532 nm.Nd:YAG laser) with latanoprost 0.005%for the control of intraocular pressure (IOP) in ocular hypertension (OHT) and open angle glaucom. (OAG). m.thods: A prospective, random.sed clinical trial in the departm.nt of Ophthalm.logy, St Thom.s’s Hospital, London, and Clayton Eye Centre, Wakefield, West Yorkshire. 167 patients (167 eyes) with either OHT or OAG were random.sed to receive 90°, 180°, and 360°SLT or latanoprost 0.005%at night and were evaluated at 1 hour, 1 day, 1 week and 1,3,6, and 12 m.nths. Results: The m.an follow up was 10.3 m.nths (range 1-12 m.nths). Early, transient, com.lications such as postoperative ocular pain, uveitis, and 1 hour IOP spike occurred in a num.er of eyes after SLT, with pain being reported m.re frequently after 360°than 90°treatm.nts (p>0.001). Success rates defined in term. of both a 20%or m.re and a 30%or m.re IOP reduction from.baseline m.asurem.nts with no additional antiglaucom.tous interventions were better with latanoprost than 90°(pd 180°SLT (pm.nts. differences in success rates between latanoprost and 360°SLT did not reach statistical significance (pd 360°com.ared to 90°SLT (pd a >20%IOP reduction and 59%a >30%reduction from.baseline. Although success rates were better with 360°than 180°SLT treatm.nts, differences did not reach statistical significance. There were no differences with regard to age, sex, race, pretreatm.nt IOP, OHT versus OAG, laser power settings, and total laser energy delivered between eyes which responded, in term. of a >20%and a >30%IOP reduction, and those that did not respond with 180°and 360°SLT treatm.nts. Conclusions: Success rates were higher with latanoprost 0.005%at night than with 90°and 180°SLT treatm.nts. 90°SLT is generally not effective. 360°SLT appears to be an effective treatm.nt with approxim.tely 60%of
