Background : ghrelin is a 28 - amino acid endogenous peptide recently identified in the secretory granules of x / a - like cells in the rat stomach, which can act on the growth hormone secretagogue receptor to accelerate the secretion of growth hormone. it was identified that ghrelin - immunoreactive cell and its receptor localize in areas of brain, such as hypothalamus ( pvn, arc ), hippocampus, adenohypophysis and so on. motilin is a 22 - amino acid peptide secreted from the upper part of the small intestine, which regulates the interdigestive motility of gastric
背景資料: ghrelin是新發現的由28個氨基酸組成的內源性腦腸肽,由胃部泌酸腺x / a樣內分泌細胞分泌, ghrelin免疫活性神經元及其受體在中樞神經系統中如下丘腦室旁核( paraventricularneucleus , pvn ) 、弓狀核( arcuatenucleus , arc ) 、海馬區及腺垂體等均有不同濃度的分佈,可與生長素促泌物受體( growthhormonesecretagoguereceptor , ghsr )結合促進生長素( growthhormone , gh )分泌。But in contrast of the research of chemical weathering of other rocks, such as granites and basalts, the research of chemical weathering of black shales both in width and depth still remains much to advance. after reading and investigating widely, we selected lower - cambrian black shales and their weathering profiles in hunan province as research objects of our work at first. then, based on field investigation of weathering status of lower - cambrian black shales and it ' s relationship with soil composition and human activities in hunan, we studied changes of chemical composition such as major and trace elements before and after weathering of black shales by comparison
根據文獻閱讀和野外調查,本文選擇了湖南安化、桃江、望城等地下寒武統黑色頁巖及有關風化剖面作為研究對象,並在查明湖南下寒武統黑色頁巖的風化現狀及其與土壤組成、人類活動的關系的基礎上,對比研究了黑色頁巖風化前後主量和微量元素等化學組成的變化,探討了元素的富集和遷移轉化機制以及黑色頁巖風化與區域環境質量的關系,得出了如下幾點主要成果和認識: ( 1 ) ti是黑色頁巖風化過程中的「不活動」元素,可作為參照元素,對其它元素的活動性進行質量平衡計算。In the light of tectonic evolution stage and metallogenesis, these metallogenic system ( assemblage ) could be classified as follows : ( 1 ) the pre - divergent metallogenic system in the southwest margin of north china paleocontinent in the archean - meso proterozoic : dongdashan iron, jinchuan nickel - copper. ( 2 ) the divergent metallogenic system in the northern margin of the qaidam paleoplate in the middle - late proterozoic : huashugou - liugouxia iron. ( 3 ) the metallogenic system in the active margin in the early paleozoic : the metallogenic assemblage in the island arc - rift in the early stage ( baiyinchang - qingshuigou copper - polymetallic ) ; the metallogenic assemblage in island arc in the middle - late stage ( honggou - jiaolongzhang copper - polymetallic ) ; the back - arc extensional basin ( zhuzhuiyaba - jiugequan - shijuli copper ) ; the metallogenic assemblage in connection with subduction and magmatic - hydatogenesis ( taergou - xiaoliugou wolfram ; huashugou - liugouxia copper ; dadonggou - diaodaban lead - zinc ) ; the metallogenic assemblage is related to the oceanic crustal shards ( dadaoerji chromite ; yushigou chromite ). ( 4 ) the metallogenic system has something to do with collision - type orogeny : the metallogenic assemblage in foreland basin ( tianlu copper ) ; the metallogenic assemblage with the intracontinental orogeny and ductile shear ( hanshan - yingzhuishan gold )
根據構造發展階段和成礦作用特點,確定本區成礦系統及組合如下: ( 1 )華北板塊西南邊緣太古宙中元古代裂解期前成礦系統:東大山鐵成礦組合,金川鎳銅成礦組合; ( 2 )柴達木板塊北緣中、新元古代裂解成礦系統:樺樹溝柳溝峽鐵成礦組合; ( 3 )加里東期活動大陸邊緣成礦系統:早期島弧裂谷成礦組合(白銀廠清水溝銅及多金屬成礦組合) ,中、晚期島弧成礦組合(紅溝蛟龍掌銅及多金屬成礦組合) ,弧后擴張盆地成礦組合(豬咀啞巴九個泉石居里銅及多金屬成礦組合) ,與俯沖作用有關的巖漿熱液成礦組合(塔爾溝小柳溝鎢成礦組合,樺樹溝柳溝峽銅成礦組合,大東溝吊大坂鉛鋅成礦組合) ,洋殼殘片成礦組合(大道爾吉鉻成礦組合,玉石溝鉻成礦組合) ; ( 4 )碰撞造山成礦系統:前陸盆地成礦組合(天鹿銅成礦組合) ,陸內造山韌性剪切成礦組合(寒山鷹咀山金成礦組合) 。Compared with farmland, the spatial distribution of orchard expressed very different characteristics. under continuous scale, distribution of orchard showed a regular pattern such as unevenness small scale : side length of the box was shorter than 8 cells - evenness small and moderate scale : the length was among 8 and 50 cells - unevenness moderate scale : the length was among 50 and 200 cells - evenness moderate and large scale : the length was longer than 200 cells ; human landscape transformation was the major impact factor of landscape changing, and a kind of moderate scale impact factor. the terrain was only a background impact factor ; during domestic landscape transforming in the working area, because the ecological maintenance value of two agricultural elements were not considered, their structural and functional equilibrium decreased gradually
果園在中尺度區間的空間分佈與農田相比表現出顯著的差異,連續尺度的空間分佈表現出不均勻小尺度:滑箱邊長小於8個像元均勻中小尺度:邊長在850個像元之間不均勻中尺度:邊長在50200個像元之間均勻中大尺度:邊長大於200個像元的變化規律4人為改造作用是景觀動態變化的主要驅動力來源,並且表現為一種中尺度影響過程,地形因子則為背景性影響因素5景觀改造活動由於未能兼顧農業組分在區域生態穩定性維護方面的價值,兩種組分的整體結構和功能穩定性有所降低。Histochemical gus assay showed that the gus staining was observed only in the mature pollen and germination pollen tube. there is no detectable gus activity in other floral organs, leaves and stems. these results suggested that st901 is a novel pollen - specific gene and the 288bp promoter fragment ( - 297 ? xfrom the translation start codon atg ) is sufficient for pollen - specific expression and os - element regulatory of st901 promoter was possibly concentrated in the region - 297 to - 9
通過對gus酶活性的組織化學定位分析,表明, st901基因啟動子驅動gus基因特異地在成熟花粉和花粉管中表達, st901基因具有花粉表達特性;且288bp ( - 297至- 9 ) ( atg定為+ 1 )的啟動子區段足以驅動gus基因在花粉中的特異表達, st901基因啟動子的花粉順式表達元件可能位於- 297至- 9之間。分享友人
