1黑龙江依兰地区蓝片岩的变质演化P-T-t轨迹显示文摘黑龙江省依兰地区出露了一套经高压变质形成的蓝片岩、云母片岩、长英质糜棱岩和少量超基性岩及大理岩并经历了强变形作用改造,一直被认为是佳木斯地块与其西侧松嫩地块碰撞拼贴所形成的缝合带产物。本次研究,通过岩相学与矿物化学分析,根据矿物组合的不同,识别出研究区内三种不同类型的蓝片岩;并获得了绿帘蓝闪石片岩(T=350~550℃,P=10~14kbar)、蓝闪霓辉石片岩(T=350~550℃,P=10~14kbar)和石榴石冻蓝闪石片岩(T=500~540℃,P=10~12kbar)的峰期变质温压条件。结合前人发表的地质年代学数据,建立了变质演化P-T-t轨迹。其中,绿帘蓝闪石片岩具"发卡式"变质演化P-T-t轨迹;而蓝闪霓辉石片岩与石榴石冻蓝闪石片岩具顺时针的演化轨迹。我们推测其成因可能为不同类型的蓝片岩形成于不同的俯冲阶段,由动力学机制的变化所造成。该研究成果为进一步探索佳木斯地块与松嫩地块碰撞拼贴的构造演化过程提供重要的依据。李伟民 刘永江 TAKASU Akira 赵英利 温泉波 郭新传 张丽 2014岩石学报2014,30,10:12
2长期冷冻脂肪的移植显示文摘目的自从脂肪抽吸术出现以来,脂肪移植便获得了广泛应用。对自体胶原和脂肪增加法进行了研究,并取得了良好效果。主张用冷冻脂肪而不用抽吸法进行反复注射。方法自1989年以来,有54例患者接受了胶原和脂肪注射。36例患者随后又接受了冷冻脂肪治疗。19例患者接受了一次注射,9例患者接受了3次注射,8例患者接受了3次以上注射。脂肪贮藏于-70℃冷冻箱中,重复注射的时间间隔为2个月至7年。结果虽然在前6周有30%~70%的再吸收,但这与新鲜脂肪的再吸收率并无差别。长期保留的脂肪已冷冻达7年之久。KATSUYA TAKASU MD SHIZU TAKASU MD 高景恒 2001实用美容整形外科杂志2001,12,6:8
3Blueschist from the Toudaoqiao Area, Inner Mongolia, NE China: Evidence for the Suture between the Ergun and the Xing'an Blocks显示文摘Blueschist accompanied by pelitic schist expose along the Xinlin-Xiguitu fault in the Toudaoqiao area, northeastern China. In this paper, the blueschist is systematically studied on the petrography and mineral chemistry. The amphiboles in the blueschist are zoned from winchite core to magnesioriebeckite/glaucophane rim to winchite outermost rim. The peak metamorphic conditions are defined by the mineral assemblage of magnesioriebeckite/glaucophane, epidote, high-Si phengite(Si<7.1), chlorite, albite, hematite and quartz, indicating an epidote-blueschist facies metamorphism. The P-T conditions are estimated as T=350–400 ℃ and P=10-12 kbar. The occurrence of the blueschist along the Xinlin-Xiguitu fault strongly suggests the fault is the suture between the Ergun and the Xing'an blocks situated in the eastern portions of the Central Asia Orogenic Belt(CAOB).Limin Zhao Akira Takasu Yongjiang Liu Weimin Li 2017Journal of Earth Science2017,28,2:5
4Zn-Rich Spinel in Association with Quartz in the Al-Rich Metapelites from the Mashan Khondalite Series, NE China显示文摘Al-rich metapelites from the Mashan khondalite series are characterized by the assemblage Spl+Grt+Sil+Crd+Bt+Pl(An72)+Kfs+Quartz+graphite. Large amounts of spinel+quartz assemblages occur as inclusions in garnet and prismatic sillimanite in the Al-rich metapelites of the Mashan complex, NE China. The chemical composition of spinel is characterized by Zn-rich(XZn=0.33–0.40. XZn=Zn/Zn+Mg+Fe*)(Fe*=Fe2++Fe3+) and Fe3+ rich(up to 0.31 p.f.u.). The characteristic chemical composition and the mineral association indicated that the formation of spinel and quartz assemblage may be due to the breakdown of Zn-rich staurolite. The geothermobarometers studies show that the peak temperature of the Mashan complex is around 820 ℃ and the peak pressures is 8.0 kbar. The Mashan complex shows a typical orogen style P-T path.Xinzhuan Guo Akira Takasu Yongjiang Liu Weimin Li 2014Journal of Earth Science2014,25,2:3
5Treatment with dimethyl fumarate ameliorates liver ischemia/reperfusion injury显示文摘AIM To investigate the hypothesis that treatment with dimethyl fumarate(D MF) mayame liorate liver ischemia/reperfusion injury(I/RI).METHODS Rats were divided into 3 groups: sham, control(CTL), and DMF. DMF(25 mg/kg, twice/d) was orally administered for 2 d before the procedure. The CTL and DMF rats were subjected to ischemia for 1 h and reperfusion for 2 h. The serum alanine aminotransferase(ALT) and malondialdehyde(MDA) levels, adenosine triphosphate(ATP), NO × metabolites, anti-oxidant enzyme expression level, antiinflammatory effect, and anti-apoptotic effect were determined.RESULTS Histological tissue damage was significantly reduced in the DMF group(Suzuki scores: sham: 0 ± 0; CTL: 9.3± 0.5; DMF: 2.5 ± 1.2; sham vs CTL, P < 0.0001; CTL vs DMF, P < 0.0001). This effect was associated with significantly lower serum ALT(DMF 5026 ± 2305 U/L vs CTL 10592 ± 1152 U/L, P = 0.04) and MDA(DMF 18.2 ± 1.4 μmol/L vs CTL 26.0 ± 1.0 μmol/L, P = 0.0009). DMF effectively improved the ATP content(DMF 20.3 ± 0.4 nmol/mg vs CTL 18.3 ± 0.6 nmol/mg, P = 0.02), myeloperoxidase activity(DMF 7.8 ± 0.4 m U/m L vs CTL 6.0 ± 0.5 m U/m L, P = 0.01) and level of endothelial nitric oxide synthase expression(DMF 0.38 ± 0.05-fold vs 0.17 ± 0.06-fold, P = 0.02). The higher expression levels of anti-oxidant enzymes(catalase and glutamatecysteine ligase modifier subunit and lower levels of key inflammatory mediators(nuclear factor-kappa B and cyclooxygenase-2 were confirmed in the DMF group.CONCLUSION DMF improved the liver function and the anti-oxidant and inflammation status following I/RI. Treatment with DMF could be a promising strategy in patients with liver I/RI.Chie Takasu Nosratola D Vaziri Shiri Li Lourdes Robles Kelly Vo Mizuki Takasu Christine Pham Seyed H Farzaneh Mitsuo Shimada Michael J Stamos Hirohito Ichii 2017World Journal of Gastroenterology2017,23,25:3
6日本梅花鹿与大丰麋鹿发情期反刍行为的差异显示文摘家养有蹄类动物的反刍行为已有大量研究,而受限于野外条件,野生有蹄类动物反刍行为的研究有限。以往研究认为,体型可能是影响动物反刍行为的重要因素。本研究以日本奈良公园日本梅花鹿Cervus nippon nippon和中国江苏大丰麋鹿Elaphurus davidianus为研究对象,观察记录并比较分析了发情期的日本梅花鹿与发情期的麋鹿在卧息时反刍行为的种内及种间差异。按照年龄性别差异,分5种类型(成年雄性、成年雌性、亚成雄性、亚成雌性和幼鹿)研究两物种食团咀嚼时间、咀嚼频率和咀嚼速率的差异。结果表明,1)日本梅花鹿的咀嚼速率和食团咀嚼时间受性别-年龄的显著影响:咀嚼速率为幼体>亚成雌性>亚成雄性>成年雌性>成年雄性,而食团咀嚼时间为成年雄性>亚成雄性>成年雌性>亚成雌性>幼体;2)性别-年龄对麋鹿咀嚼频率有显著的影响,成年雄性<成年雌性<亚成雄性<亚成雌性<幼体;3)两物种在咀嚼频率、食团咀嚼时间和咀嚼速率上的差异均有统计学意义,体型更大的麋鹿咀嚼速率更慢,食团咀嚼时间更长。与体型相关的性别及年龄显著影响了日本梅花鹿和麋鹿的反刍行为。张宜贵 Ullah Sana Takasu Fugo 李忠秋 2020四川动物2020,39,1:2
7Why cuckoos should parasitize parrotbills by laying eggs randomly rather than laying eggs matching the egg appearance of parrotbill hosts?显示文摘The coevolutionary interaction between cuckoos and their hosts has been studied for a long time, but to date some puzzles still remain unsolved. Whether cuckoos parasitize their hosts by laying eggs randomly or matching the egg morphs of their hosts is one of the mysteries of the cuckoo problem. Scientists tend to believe that cuckoos lay eggs matching the appearance of host eggs due to selection caused by the ability of the hosts to recognize their own eggs.In this paper, we first review previous empirical studies to test this mystery and found no studies have provided direct evidence of cuckoos choosing to parasitize host nests where egg color and pattern match. We then present examples of unmatched cuckoo eggs in host nests and key life history traits of cuckoos, e.g. secretive behavior and rapid egg-laying and link them to cuckoo egg laying behavior. Finally we develop a conceptual model to demonstrate the egg laying behaviour of cuckoos and propose an empirical test that can provide direct evidence of the egg-laying properties of female cuckoos. We speculate that the degree of egg matching between cuckoo eggs and those of the host as detected by humans is caused by the ability of the hosts to recognize their own eggs, rather than the selection of matching host eggs by cuckoos. The case of Common Cuckoos(Cuculus canorus) and their parrotbill hosts(Paradoxornis alphonsianus), where it has been shown that both have evolved polymorphic eggs(mainly blue and white), was used to develop a conceptual model to demonstrate why cuckoos should utilize parrotbill hosts by laying eggs randomly rather than laying eggs matching the appearance of host eggs.In conclusion, we found no evidence for the hypothesis that cuckoos lay eggs based on own egg color matching that of the parrotbill-cuckoo system. We argue theoretically that laying eggs matching those of the hosts in this system violates a key trait of the life history of cuckoos and therefore should be maladaptive.Canchao Yang Fugo Takasu Wei Liang Anders P Moller 2015Chinese Birds2015,,2:2
