Organ Specific Tumor Markers: What’s New?

Tumor markers are molecules produced in the body in response to cancer. An ideal tumor marker should have high sensitivity and specificity, should be cheap, and should be easily detected in body fluids. Identification of novel markers is important and it is expected that with the advent of newer technologies, more reliable markers will be discovered. This review discusses the currently available tumor markers for different malignancies.

应用烃类流体包裹体GOI和成分研究凝析气藏成藏过程：以准噶尔盆地莫索湾地区为例

The Grains containing Oil Inclusions （GOI） data in currently gas/condensate-beating Jurassic and Cretaceous reservoir sandstones of Well Pen 5 （the Mosuowan area of central Junggar Basin, NW China） are generally greater than the empirical threshold line of 5%. This is consistent with the gas-condensate section originally containing a palaeo-oil column. In order to assess the origin of the oil trapped in the oil inclusion and its relationship to the free oil/gas-condensate, a detailed molecular geochemical study was carried out for correlation between the free and inclusion oils. The paleo oil is most likely sourced from the Lower Permian Fengcheng Formation, which generated hydrocarbons primarily during Late Triassic and the oils were later secondarily altered and dysmigrated along faults likely during Late Jurassic-Early Cretaceous. In contrast, the current reservoired oil/gas-condensate mainly derived from the Middle Permian Lower Wuerhe Formation, whose peak generation time last from Late Cretaceous even to the present. This paper showed that integrated oil-bearing fluid inclusion analyses have likely allowed a complex multi-phase charge history to be recognized and resolved with a high degree of confidence.
