1An examination by GC×GC-TOFMS of organic molecules present inhighly degraded oils emerging from Caribbean terrestrial seeps of Cretaceous age显示文摘For our ancestors, oil seeps were both a fascination and a resource but as the planet's reserves of high quality low density oil becomes increasingly depleted, so there is now a renewed interest in heavier,biodegraded oils such as those encountered in terrestrial seeps. One such seep is Pitch Lake in the Caribbean island of Trinidad, which is the largest natural deposit of asphalt in the world. At the northern end of the Caribbean, oil emerges along a tectonic contact on the island on Cuba. The sources of the oils from these seeps are relatively recent and both are subject to intense weathering due to the tropical conditions. When analysed by gas chromatography(GC) both oils appear as unresolved complex mixtures(UCM) and show a very high degree of biodegradation thus presenting an analytical challenge. In this case study, these two Caribbean seep oils were analysed by comprehensive two dimensional GC with time of flight mass spectrometry(GC×GC-TOFMS) to expose many thousands of the individual compounds that comprise the UCM. The high chromatographic resolution of the GC×GC-TOFMS produced good quality mass spectra allowing many compounds including molecular fossil ‘biomarkers' to be identified. Compound classes included diamondoid hydrocarbons, demethylated hopanes and secohopanes, mono-and tri-aromatic steroids. D-ring aromatised structures of the 8,14-seco-hopanes,including demethylated forms were present in both oils but further demethylation, probably at position C-25 during biodegradation, was only observed in the Pitch Lake oil. Many polycyclic aromatic hydrocarbons(PAHs) were absent although the fungal-derived pentacyclic PAH perylene was present in both oils. The presence of the angiosperm biomarker lupane in the Pitch Lake oil constrained the age to the Late Cretaceous. The higher degree of biodegradation observed in the Cuban oil was likely due to relatively slow anaerobic processes whereas oil within Pitch Lake was probably subject to additional more rapid aerobic metabolism within the lake.Alan G.Scarlett Ana Ibis Despaigne-Diaz Simon A.Wilde Kliti Grice 2019Geoscience Frontiers2019,10,1:5

3A laboratory modification to testicular sperm preparation technique improves spermatogenic cell yield显示文摘阴囊的精子抽取是过去常与 nonobstructive 精子缺乏在人发现 spermatogenic 房间的一个普通过程。biopsied 处理阴囊的纸巾的实验室需要细致地被表现获得房间的高收益。在这研究,在阴囊的活体检视以后切碎纸巾的有效性用组织学的评估被估计,作为在密度坡度 centrifugation 期间是 spermatogenic 房间的迁居上的剩余织物的可能的不利效果。当与精子一起在密度坡度媒介上放了时,我们的结果显示那阴囊的剩余纸巾洗,妨碍 spermatogenic cells’在 centrifugation 期间形成一个小团,并且因此损害 intracytoplasmic 精子注射过程。而从精子的恢复房间的吝啬的数字与剩余织物洗媒介(SWM ) 是 39.435 ±24.849,它尤其是更高(60.189 ±28.214 个房间) 在没有切碎的纸巾的 SWM。留下的织物没在组织学的节包含功能的生精的小管或 spermatogenic 房间。在结论,在切碎阴囊的织物不增加的 biopsied 以后的留下的剩余织物对 spermatogenic 房间检索的任何功能或细胞的贡献;事实上,它可以阻止通过坡度层移居在 centrifugation 和 spermatogenic 房间的原因损失期间形成一个小团在伴随的房间暂停接近细胞的元素。Sinan Ozkavukcu Ebru Ibis Sule Kizil Suheyla Isbacar Kaan Aydos 2014Asian Journal of Andrology2014,16,6:2
