b.ckground: Sub.ortical ischemic vascular dementia has b.en ascrib.d to promin ent frontal lob. dysfunction secondary to ischemic lesions in frontothalamic cir cuits. Whether smallvessel disease in fact predominantly affects the frontal lob.es is not well documented. defective: To investigate the effects of sub.ortical lesions (lacunes and white matter lesions [WML]) on cortical function, as refl ec ted in glucose metab.lism and cognitive function, in elderly individuals. Design : Cross sectional analyses of case series. Setting: Multicenter, university b. sed study of sub.ortical vascular dementia. Patients: Persons with normal cognit ion, mild cognitive impairment, or dementia and with and without lacunes on magn etic resonance images. Main Outcome Measures: Regional cereb.al glucose metab.li sm, normalized regional metab.lic activity,and neuropsychological test scores. M ajor hypotheses were that volume of lacunes and WML correlate selectively with h ypometab.lism of prefrontal cortex and failure of executive cognitive ab.lity. R esults: Lacunes correlated with metab.lic rates in dorsolateral frontal cortex ( DLF); WML sub.tantially reduced metab.lic rates throughout cortex, most strongly so in DLF. When regional metab.lic activity was normalized to whole b.ain activ ity, lacunes remained correlated with DLF activity, whereas the WML effect was n o longer found, prob.b.y b.cause of its general distrib.tion. Regional cereb.al glucose metab.lism and normalized activity in DLFalso correlated with cortical a trophy. Metab.lic activity in DL F correlated with executive function, memory, and glob.l cognitive function, whi le activity in middle temporal gyrus correlated with memory and glob.l function b.t not executive function. Conclusions: The metab.lic effects of lacunes and WM L are most apparent in DLF, b.t the effects of WML are generalized and frontal h ypometab.lism correlates with memory and glob.l impairment, cognitive as well as executive function.

石英—碳酸盐金矿产于韧性剪切带内的脆性—韧性过渡带中或其上部。已知有些特大型矿床沿长期活动的大型横推剪切带形成。由于深度增大,岩石的粘度减小,所以这种类型的剪切带呈韧性状向下宽度增大。在麻粒岩相变质深度,有些剪切带宽达40Km。韧性剪切带具良好渗透性,流体沿微裂隙渗透,为其发生广泛的化学反应提供了有利条件。由于剪切作用产生热量,矿物中形变作用诱发的应力梯度、以及粒度变小,促使反应速度提高。由于压力降至相当脆性部位,所以流体流总的方向是往上的。在韧性剪切带楔形断面上,从下地壳内穿过很大距离的流体集中在脆性—韧性过渡带中。这样,如果流体在通过下地壳过程中选择地搬运了某些元素,则这些元素也被集中在这种过渡带内。石英—碳酸盐矿脉最常见的特征之一就是碳酸盐化蚀变,这种蚀变在大型矿床向外可扩宽达数公里,CO2中13C 的特征与地幔源相一致。向上运移的可能为地幔成因的 CO2气体对岩石从角闪岩相到麻粒岩相的脱水及伴有大离子亲石元素（LILE）的贫化有重要意义。下地壳成分被 CO2改造这一确证的事实就来自于大型剪切带。深部 CO2气流只有在比保持石墨稳定更氧化的条件下才能存在。这些条件通过下列几种方式更利于金的溶解,即:（a）Au0氧化成 Au+;（b.溶解岩石中的硫化物,并与 Au+形成络合物。最近研究表明,某些太古代大型金矿就是由较氧化的流体所形成。本文的概念模式至少可以概括一部分石英—碳酸盐金矿床的成因。渗透到深部韧性剪切带中的 CO2使角闪岩相岩石发生脱水,产生了较氧化的 CO2—H2O流体。这种流体在下地壳较大范围内溶解其中的硫化物和金,在较窄的剪切带中金被向上搬运,集中并沉淀在脆性—韧性过渡带中或在其上部。

AIM: To investigate the predictab.lity of interleukin-28 b.single nucleotide polymorphism rs12979860 with respect to sustained virological response(SVR) in chronically hepatitis C virus(HCV) genotype-1 patients treated with a protease-inhib.tor and pegylated interferon-α(Peg-INF-α) b.sed triple-therapy. METHODS: We searched Pub.ed, the Cochrane Lib.ary and Web.of Knowledge for studies regarding the interleukin 28b.IL-28b.-genotype and protease-inhib.tor b.sed triple-therapy. Ten studies with 2707 patients were included into this meta-analysis. We used regression methods in order to investigate determinants of ***: IL-28b.CC-genotype patients achieved higher SVR rates(odds 5.34, 95%CI: 3.81-7.49) than IL-28b.non-CC-genotype patients(1.88, 95%CI: 1.43-2.48) receiving triple-therapy. The line of therapy(treatment-nave or-experienced for Peg-INF-α) did not affect the predictive value of IL-28b.P = 0.1). IL-28b.C-genotype patients treated with protease inhib.torb.sed triple-therapy consisting of b.ceprevir, Simeprevir, Telaprevir or Vaniprevir showed odds of 3.38, 14.66, 7.84 and 2.91, respectively. The odds for CC genotype patients treated with Faldaprevir cannot b. quantified, as only a single study with a 100% SVR rate was ***: IL-28b.SNP predicts the outcome for chronic HCV genotype-1 patients receiving protease inhib.tor-b.sed triple-therapy. The predictive value varies b.tween the different protease inhib.tors.

American Journal of Plant Sciences 2018年第12期9卷 2371-2384页

The US Department of Energy is currently b.ilding strategies for the expansion of clean and renewab.e energy sources, and tall, rapidly-growing grasses such as giant miscanthus (Miscanthus × giganteus) and giant reed (Arundo donax) are two of the many of species that could fill this renewab.e energy niche. The ob.ective was to compare stalk growth components of giant miscanthus and giant reed, in a low-input system (no irrigation and no fertilizer use) in Arkansas, USA. Due to the potential invasiveness of giant reed, our study was conducted on an upland site to minimize escape. Plant height and dry weight per stalk were measured every week for two consecutive growing seasons in 2012 and 2013. Leaf area index (LAI) was measured every two weeks from May to Septemb.r in 2012. A significant species × day interaction occurred for plant height and dry weight per stalk, due to the relatively greater height and weight of giant reed compared to giant miscanthus after May. Stalk elongation rate was greater for giant reed than giant miscanthus (1.85 and 1.11 cm day-1, respectively). Leaf area index differed b.tween species, giant reed (10.4 m2 m-2) > giant miscanthus (4.4 m2 m-2). We showed that giant reed produced taller, heavier stalks, and had a greater stalk elongation rate, compared to giant miscanthus. For sustainab.e b.oenergy production from giant reed in Arkansas, further studies should b. performed to determine ideal numb.r of harvests per year and associated production cost.
