1Teleconnections of Inter-Annual Streamflow Fluctuation in Slovakia with Arctic Oscillation,North Atlantic Oscillation,Southern Oscillation,and Quasi-Biennial Oscillation Phenomena显示文摘纸的目的是分析伪二年的摆动( QBO )的一个可能的电视连接,南部的摆动(那么),诺思大西洋摆动( NAO ),并且有 Bela 河( 1895-2004 )和 Cierny Hron 河( 1931-2004 )(中央斯洛伐克)的长期的流速及流水量变化的北极摆动( AO )现象。同质,长期的趋势,以及内部年度的干燥、湿的周期在 Bela 河的全部 1895-2004 时间序列并且在 Cierny Hron 河的 1931-2004 时间序列被分析。内部年度的变化湿并且干燥期用光谱分析被识别。最重要的时期是 3.6 年的。另外的重要时期是 2.35 年, 13.5 年,和 21 年的那些。自从这些,时期在世界的另外的河里,以及在被发现那么, NAO,和 AO 现象,他们能被看作关于地球的一般整齐。Pavla PEKAROVA Jan PEKAR 2007Advances in Atmospheric Sciences2007,24,4:8
2Wheat streak mosaic virus: incidence in field crops, potential reservoir within grass species and uptake in winter wheat cultivars显示文摘Wheat streak mosaic virus(WSMV)has become a re-emerging pathogen in cereal crops in the Czech Republic.WSMV was first reported in the former Czechoslovakia in the early 1980s,and then no record of the virus was documented until 2009.The incidence of the virus was recorded in recent years in several winter wheat fields and many grass species.Here,we surveyed the incidence of WSMV in cereal crops.The results demonstrated the existence of the virus in winter wheat and volunteer wheat during each year of the monitoring period,which spanned from 2013–2016.Although the range of infected samples was low(6.4%of the total tested samples),a high incidence of well-distributed virus was recorded.In at least six fields,the virus reached severe and potentially epidemic levels.In accordance with our previous report detailing WSMV infection of native grasses,we tested several grass species commonly grown in the Czech Republic.We found that some grass species acted as experimental hosts and possible reservoirs of the virus;these included Anthoxanthum odoratum(sweet vernal grass),Arrhenatherum elatius(false oat-grass),Lolium multiflorum(Italian rye-grass),Bromus japonicus(Japanese chess),Echinochloa crus-galli(barnyard grass),Holcus lanatus(meadow soft grass)and Holcus mollis(creeping soft grass).Some of these grass species are also important weeds of cereals,which may be the potential source of WSMV infection in cereal crops.Several widely used winter wheat cultivars were tested in the field after artificial inoculation with WSMV to evaluate virus titre by RT-qPCR.Overall,the tested cultivars had a low virus titre,which is associated with mild disease symptoms and may provide a good level of crop resistance to WSMV.Jana Chalupniková Jiban Kumar Kundu Khushwant Singh Pavla Bartaková Eva Beoni 2017Journal of Integrative Agriculture2017,16,3:4

4Does combined therapy of curcumin and epigallocatechin gallate have a synergistic neuroprotective effect against spinal cord injury?显示文摘Systematic inflammatory response after spinal cord injury(SCI) is one of the factors leading to lesion development and a profound degree of functional loss. Anti-inflammatory compounds, such as curcumin and epigallocatechin gallate(EGCG) are known for their neuroprotective effects. In this study, we investigated the effect of combined therapy of curcumin and EGCG in a rat model of acute SCI induced by balloon compression. Immediately after SCI, rats received curcumin, EGCG, curcumin + EGCG or saline [daily intraperitoneal doses(curcumin, 6 mg/kg; EGCG 17 mg/kg)] and weekly intramuscular doses(curcumin, 60 mg/kg; EGCG 17 mg/kg)] for 28 days. Rats were evaluated using behavioral tests(the Basso, Beattie, and Bresnahan(BBB) open-field locomotor test, flat beam test). Spinal cord tissue was analyzed using histological methods(Luxol Blue-cresyl violet staining) and immunohistochemistry(anti-glial fibrillary acidic protein, anti-growth associated protein 43). Cytokine levels(interleukin-1β, interleukin-4, interleukin-2, interleukin-6, macrophage inflammatory protein 1-alpha, and RANTES) were measured using Luminex assay. Quantitative polymerase chain reaction was performed to determine the relative expression of genes(Sort1, Fgf2, Irf5, Mrc1, Olig2, Casp3, Gap43, Gfap, Vegf, NfκB, Cntf) related to regenerative processes in injured spinal cord. We found that all treatments displayed significant behavioral recovery, with no obvious synergistic effect after combined therapy of curcumin and ECGC. Curcumin and EGCG alone or in combination increased axonal sprouting, decreased glial scar formation, and altered the levels of macrophage inflammatory protein 1-alpha, interleukin-1β, interleukin-4 and interleukin-6 cytokines. These results imply that although the expected synergistic response of this combined therapy was less obvious, aspects of tissue regeneration and immune responses in severe SCI were evident.Jiri Ruzicka Lucia Machova Urdzikova Barbora Svobodova Anubhav G.
