2Significance of endothelial dysfunction in the pathogenesis of early and delayed radiation enteropathy显示文摘This review summarizes the current state of knowledge regarding the role of endothelial dysfunction in the pathogenesis of early and delayed intestinal radiation toxicity and discusses various endothelial-oriented interventions aimed at reducing the risk of radiation enteropathy. Studies published in the biomedical literature during the past four decades and cited in PubMed, as well as clinical and laboratory data from our own research program are reviewed. The risk of injury to normal tissues limits the cancer cure rates that can be achieved with radiation therapy. During treatment of abdominal and pelvic tumors, the intestine is frequently a major dose-limiting factor. Microvascular injury is a prominent feature of both early (inflammatory), as well as delayed (fibroproliferative) radiation injuries in the intestine and in many other normal tissues. Evidence from our and other laboratories suggests that endothelial dysfunction, notably a deficiency of endothelial thrombomodulin, plays a key role in the pathogenesis of these radiation responses. Deficient levels of thrombomodulin cause loss of vascular thromboresistance, excessive activation of cellular thrombin receptors by thrombin, and insufficient activation of protein C, a plasma protein with anticoagulant, anti-inflammatory, and cytoprotective properties. These changes are presumed to be critically involved in many aspects of early intestinal radiation toxicity and may sustain the fi broproliferative processes that lead to delayed intestinal dysfunction, fi brosis, and clinical complications. In conclusion, injury of vascular endothelium is important in the pathogenesis of the intestinal radiation response. Endothelial-oriented interventions are appealing strategies to prevent or treat normal tissue toxicity associated with radiation treatment of cancer.Junru Wang Marian Boerma Qiang Fu Martin Hauer-Jensen 2007World Journal of Gastroenterology2007,13,22:20

5Mitochondrial protection by low doses of insulin-like growth factor-Ⅰin experimental cirrhosis显示文摘AIM: To characterize the mitochondrial dysfunction in experimental cirrhosis and to study whether insulin-like growth factor-Ⅰ(IGF-Ⅰ) therapy (4 wk) is able to induce beneficial effects on damaged mitochondria leading to cellular protection. METHODS: Wistar rats were divided into three groups: Control group, untreated cirrhotic rats and cirrhotic rats treated with IGF-Ⅰtreatment (2 μg/100 g bw/d). Mitochondrial function was analyzed by flow cytometry in isolated hepatic mitochondria, caspase 3 activation was assessed by Western blot and apoptosis by TUNEL in the three experimental groups. RESULTS: Untreated cirrhotic rats showed a mitochon- drial dysfunction characterized by a significant reduction of mitochondrial membrane potential (in status 4 and 3); an increase of intramitochondrial reactive oxigen species (ROS) generation and a significant reduction of ATPase activity. IGF-Ⅰtherapy normalized mitochondrial func-tion by increasing the membrane potential and ATPase activity and reducing the intramitochondrial free radical production. Activity of the electron transport complexes Ⅰand Ⅲ was increased in both cirrhotic groups. In addition, untreated cirrhotic rats showed an increase of caspase 3 activation and apoptosis. IGF-Ⅰtherapy reduced the expression of the active peptide of caspase 3 and resulted in reduced apoptosis.Raquel Pérez María García-Fernández Matías Díaz-Sánchez Juan E Puche Gloria Delgado Marian Conchillo Jordi Muntané Inma Castilla-Cortázar 2008World Journal of Gastroenterology2008,14,17:11
6高温胁迫下不同热敏感性小麦光化学活性和能量分配差异显示文摘利用叶绿素荧光技术,研究高温胁迫下不同热敏感性小麦品种光化学活性和能量分配的差异。结果表明:在37.5℃以上的高温胁迫下,与热敏感的小麦品种‘Torysa’相比,耐热品种‘Ilona’通过保持高的PSII最大光化学效率(φPo)、捕获的能量向电子传递链传递的效率(ψo)以及用于电子传递的量子产额(φEo)使更多的能量被反应中心捕获并进入电子传递链,而热敏感品种‘Torysa’中较高的用于热耗散的量子比率(φDo)表明其更多的能量用于热耗散,从而使得‘Ilona’中光化学反应可以利用的能量多于‘Tor ysa’。与此同时,‘Ilona’还有相对更多的PSI参与环式电子传递,耗散多余的能量,从而减少活性氧的产生。因而在高温胁迫下,‘Ilona’能够维持较高的光化学效率,降低光抑制,具有更好的耐热性。张会玲 Marian Brestic Katarina Olsovska 李刚 孟庆伟 杨兴洪 2015植物生理学报2015,51,7:10
7丫环的诱惑——白薇对宝玉访晴雯的颓废主义叙述显示文摘白薇是中国颓废主义创作阶段的代表作家之一。论文以白薇的坎坷人生经历为切入点,深刻分析了其颓废主义创作手法形成的原因及发展过程。从白薇的第一部剧作《琳丽》开始,美与爱的主题就开始显现。到了《访雯》,白薇就达到了颓废主义创作的顶峰。《访雯》与意大利文学家加百列·邓南遮的《死城》有着众多相似之处。爱、死和美是两部剧作中共同关心的主题;宝玉跟晴雯的绵绵爱意与里奥纳多跟妹妹玛丽亚之间的爱情都属非比寻常的兄妹之恋;两部剧都注重了对场景和情节的刻画,反映出颓废主义的精神特征。但是,如果从女性解放的角度分析,白薇笔下晴雯的形象已经超越了邓南遮的玛丽亚;同时,宝玉的形象又为亚莱桑特罗这个人物所不及。总之,白薇《访雯》的创作源头很可能来自邓南遮的《死城》,并且在一定程度上有所超越,因而备受关注。马利安.高利克(Marian Galik) 李燕 2004海南师范学院学报(社会科学版)2004,17,5:9
8常压等离子体退除PVA浆料机理探讨显示文摘通过常压等离子体处理进行PVA失重、PVA浆料在水中溶解率的变化、等离子体处理与常规H2O2退浆比较分析以及PVA薄膜的XPS和FT-IR分析,讨论常压等离子体对PVA作用的机理。结果表明,常压等离子体作用使部分PVA大分子氧化成小分子如CO2、H2O而直接消失在空气中,另一部分PVA大分子被氧化降解成分子链较短的分子,提高了其在水中的溶胀、溶解性。蔡再生 邱夷平 Marian McCord 2005纺织学报2005,26,6:8

11Diagnosing physical conditions near the flare energy-release sites from observations of solar microwave typeⅢbursts显示文摘In the physics of solar flares, it is crucial to diagnose the physical conditions near the flare energyrelease sites. However, so far it is unclear how to diagnose these physical conditions. A solar microwave type Ⅲ burst is believed to be a sensitive signature of primary energy release and electron accelerations in solar flares. This work takes into account the effect of the magnetic field on the plasma density and develops a set of formulas which can be used to estimate the plasma density, temperature, magnetic field near the magnetic reconnection site and particle acceleration region, and the velocity and energy of electron beams.We apply these formulas to three groups of microwave type Ⅲ pairs in an X-class flare, and obtained some reasonable and interesting results. This method can be applied to other microwave type Ⅲ bursts to diagnose the physical conditions of source regions, and provide some basic information to understand the intrinsic nature and fundamental processes occurring near the flare energy-release sites.Bao-Lin Tan Marian Karlicky Hana Mészárosová Guang-Li Huang 2016Research in Astronomy and Astrophysics2016,16,5:5

13Complete and phase synchronization in a heterogeneous small-world neuronal network显示文摘Synchronous firing of neurons is thought to be important for information communication in neuronal networks. This paper investigates the complete and phase synchronization in a heterogeneous small-world chaotic Hindmarsh- Rose neuronal network. The effects of various network parameters on synchronization behaviour are discussed with some biological explanations. Complete synchronization of small-world neuronal networks is studied theoretically by the master stability function method. It is shown that the coupling strength necessary for complete or phase synchronization decreases with the neuron number, the node degree and the connection density are increased. The effect of heterogeneity of neuronal networks is also considered and it is found that the network heterogeneity has an adverse effect on synchrony.韩芳 陆启韶 Wiercigroch Marian 季全宝 2009Chinese Physics B2009,18,2:5
14银杏叶提取物联合糖皮质激素对变应性鼻炎小鼠嗅觉功能及炎症因子的影响显示文摘目的:研究银杏叶提取物联合糖皮质激素是否可以显著改善变应性鼻炎伴嗅觉障碍小鼠嗅黏膜的炎症反应,对变应性鼻炎所致嗅觉障碍起到治疗作用。方法:利用卵清蛋白对实验组小鼠进行造模,选取变应性鼻炎伴嗅觉障碍的30只小鼠分为3组:组1给予地塞米松和大剂量银杏叶提取物(n=10);组2给予地塞米松和小剂量银杏叶提取物(n=10);组3仅给予地塞米松(n=10)。连续给药两周。观察嗅黏膜形态结构的改变,比较小鼠血清中细胞因子IL-4、IFN-γ、caspase-1的检测结果。结果:治疗后,组1小鼠嗅觉显著强于组3小鼠(P<0.05)。各组caspase-1水平第2周较第1周均有显著提高。各组小鼠IFN-γ水平第2周较第1周均有显著降低。组1及组2小鼠IL-4水平第2周较第1周明显降低。各组IFN-γ/IL-4水平第2周较第1周均有显著降低。结论:与单纯应用糖皮质激素治疗相比,糖皮质激素联合银杏叶提取物具有更好的抗炎作用,可以在一定程度上提高变应性鼻炎所致嗅觉障碍的治疗效果。吴婵 魏永祥 PINTO Jayant Marian 田俊 袁先道 占小俊 2018临床耳鼻咽喉头颈外科杂志2018,32,2:5
15Soil Stabilizing Capability of Three Plant Species Growing on the Three Gorges Reservoir Riverside显示文摘Plant regrowth capacity and soil protection were investigated using three flooding-tolerant Yangtze River riverside species (Arundinella anomala, Hemartria compressa and Cynodon dactylon). The root and leaf surface growth, the plant regrowth capacity and the mitigation of soil runoff were analyzed using potted plants that were covered with 5, 10 and 18 cm new sediments, respectively. A. anomala reacted most slowly to the recovery from new sediments, while H. compressa had the highest recovery rates. The latter could produce 24 times the initial root length and 41 times its original leaf surface during the growth period of 12 weeks. C. dactylon showed no significant change in growth in relation to the rising sediment thickness, which means that even 18 cm of new sediments were tolerated by C. dactylon. Erosion tests showed that all three plant species can reduce the soil runoff by more than 63%. Compared to other species, A. anomala was less capable of stabilizing new sediments. The soil protecting abilities of H. compressa decreased after more than 10 cm of new sediments. C. dactylon showed the best soil retention compared to the other species examined, since it could reduce the soil runoff up to 87%. Consequently, C. dactylon was found to be significantly better for soil-protection plant species than A. anomala and H. compressa given the conditions at the Three Gorges Reservoir.Norbert Tenten 曾波 Marian Kazda 2010Journal of Earth Science2010,21,6:4

17A novel smooth and discontinuous oscillator with strong irrational nonlinearities显示文摘In this paper,we propose a novel nonlinear oscillator with strong irrational nonlinearities having smooth and discontinuous characteristics depending on the values of a smoothness parameter.The oscillator is similar to the SD oscillator,originally introduced in Phys Rev E 69(2006).The equilibrium stability and the complex bifurcations of the unperturbed system are investigated.The bifurcation sets of the equilibria in parameter space are constructed to demonstrate transitions in the multiple well dynamics for both smooth and discontinuous regimes.The Melnikov method is employed to obtain the analytical criteria of chaotic thresholds for the singular closed orbits of homoclinic,homo-heteroclinic,cuspidal heteroclinic and tangent homoclinic orbits of the perturbed system.HAN YanWei CAO QingJie CHEN YuShu WIERCIGROCH Marian 2012Science China(Physics,Mechanics & Astronomy)2012,55,10:4
18电化学氢压缩和纯化与竞争技术的对比:Ⅱ.电催化的挑战显示文摘在未来的几十年里,氢将成为世界能源政策的基础,因为它的脱碳性质,至少在可再生能源生产时是如此.目前,氢基本上仍然是从化石原料中生产出来的(在某种程度上来自于生物质);因此,目前市场上的氢气含有不可忽略的杂质,这些杂质阻碍了氢气立即用于特殊化学或作为燃料电池的能量载体,例如在运输应用(汽车、公共汽车、火车、船只等)中逐渐扩散到地球上.因此,氢气必须具有足够的纯度,但也必须充分压缩(在高压下,通常为70 MPa),这使得氢气循环中不可避免存在净化和压缩步骤.如本文第一部分'电化学氢压缩和净化与竞争技术的对比--第一部分:优缺点'所示,电化学氢压缩机(EHCs)能够实现氢净化和压缩,具有比它们相应的机械设备更多的理论(热力学)和实际(动力学)的优越性.然而,为了具有竞争力, EHCs必须在非常密集的条件下运行(高电流密度和低电池电压),只有在其核心材料(如膜和电极/电催化剂)经过优化后才能达到.本文将特别关注电催化剂在EHCs中必须表现出的特性:在杂质存在的情况下它们应促进(非常)快速的氢氧化反应(HOR),这意味着它们对毒物也具有(非常)耐受性.这包括操作氢气净化压缩所用的EHC阳极的先决条件,而大量低温燃料电池文献中为耐受毒性而开发的材料可能并不总是满足这两个标准,正如本综述所阐述的.Marine Tregaro Maha Rhandi Florence Druart Jonathan Deseure Marian Chatenet 2020Chinese Journal of Catalysis2020,41,5:4
19Intestinal pseudo-obstruction caused by herpes zoster:Case report and pathophysiology显示文摘Herpes zoster(HZ) infection occurs in approximately 10% to 30% of individuals. Visceral neuropathies secondary to HZ can cause cystitis and urinary retention. But colonic pseudo-obstruction can also occur. Peripheral neuropathy may reveal segmental motor paresis of either upper or lower limbs, the abdominal muscles or the diaphragm. We report the case of a 62-year-old male patient who presented with abdominal distention and cutaneous vesicular eruption on the left side of the abdominal wall. Plain X-rays and computed tomography scan showed distended small bowel. A diagnosis of intestinal pseudo-obstruction was made secondary to segmental paresis of the small intestine and visceral neuropathy. Conservative management was successful and the patient was discharged uneventfully. Intestinal pseudo-obstruction ought to be consideredwhen dealing with non-obstructive(adynamic) conditions of the digestive tract associated with HZ infection; since early recognition may help to avoid unnecessary surgery.Roberto Anaya-Prado José V Pérez-Navarro Ana Corona-Nakamura Michelle M Anaya-Fernández Roberto Anaya-Fernández Marian Eliza Izaguirre-Pérez 2018World Journal of Clinical Cases2018,6,6:4
