The STRATAFORM program sponsored by the Office of Naval Research (Nittrouer and Kravitz, 1996, this issue) seeks to understand how sedimentary processes lead to the formation of the stratigraphic sequ...
Paratetramitus jugosus, a vahlkampfiid amoebomastigote, was isolated into monoprotist/monobacterial (Bacillus sp.), cultures from laminated microbial mats (Laguna Figueroa, Baja California Norte, Mexi...

At the end of their life cycle, American eel (Anguilla rostrata) migrate to the Sargasso Sea from freshwater habitats along the east coast of North America in order to spawn planktonic eggs. The eggs...
This study was conducted to re-evaluate the dietary vitamin C requirement in juvenile eel, Anguilla japonica by using L-ascorbyl-2-monophosphate (AMP) as the vitamin C source. Five semi-purified exper...
This study was conducted to evaluate the effects of dietary arachidonic acid (AA, 20:4n-6) levels on growth performance and body composition in juvenile eel, Anguilla japonica. Six semi-purified exper...
Eels are submitted to hydrostatic pressure (HP) during their spawning migration (about 6000 Km). Before migration, they change from the yellow to the silver stage (silvering process). The effects of H...
Aerobic metabolism which is required for long swimming activities during the eel's spawning migration at depth, is a potential target for pressure effects due to its components located in the inner mi...
We performed a multibeam survey of Eel Canyon, offshore northern California. The survey revealed a signifi cant bend in the canyon that appears to be due to the oblique compressional tectonics of the ...
摘要冰冻海洋中生存的南极eel pout( Lycodichthys dearborni)体内能合成高浓度的Ⅲ型抗冻蛋白(AFP Ⅲ)。为了寻找新的AFP Ⅲ基因,构建了L.dearborni肝脏cDNA文库。通过斑点杂交筛选此文库,发现一个2.87 kb的cDNA克隆,LD12。序列分析采用DNAssist2.0和ClustalX 1.8软件。结果显示,LD12分子由12个串联重复的片段构成,每...
摘要 采用高密点阵技术从黄鳝雄性性腺cDNA文库中获得8个克隆,序列分析和BLAST结果显示它们编码的蛋白质分别与40S核糖体蛋白S4,S9,S16,S17,S20和60S核糖体蛋白L7, L18a,L29高度同源。 根据黄鳝RP蛋白序列和其他物种的相应同源序列构建ML系统发生树,显示核糖体蛋白基因在进化中高度保守。核糖体蛋白基因不仅可作为分子进化分析的有利工具,而且从它们的表达模式显示RP基因...
摘要动物脂肪组织中的甘油三酯在数量上是最重要的储存能源。Hsl基因所编码的激素敏感性脂肪酶是一种多功能酶。它通过催化水解储存在脂肪组织中的甘油三酯,以及卵巢、肾上腺、睾丸和胎盘中的胆固醇酯,在机体能量供应和类固醇生成作用中发挥重要作用。本研究以放射性同位素和地高辛标记重组质粒pBS中所含猪Hsl基因作为探针,分别与Pst Ⅰ酶切的黄鳝基因组总DNA和有丝分裂染色体标本进行Southern杂交和荧光...
