The team developed a siRNA product that specifically blocks the transcription of the gene that codes for IL-8, thereby blocking production of this protein, and encases it in a liposome delivery system. In mouse studies, this product showed activity against 2 ovarian cancer cell lines, both when used alone and when used in combination with docetaxel. In addition, the mouse studies revealed that the product was decreasing tumor growth through anti-angiogenic mechanisms — the treated tumors showed a lower microvessel density, the researchers report. This product was "highly effective in our preclinical studies and may merit clinical development," they write. However, they also caution that the cell lines used to create the mouse models might not accurately reflect the heterogeneity seen in human tumors.

In chapter two,based on the ultraviolet/infrared scale separation of the connection decomposition variables,we proposed that at the classic level the strong-coupling limit of the Yang-Mills theory vacuum behaves as a black hole with regard to colors.With this idea,we prove that there exists a dual superconductor solution for the strongly-coupled Yang-Mills theory,whose vacuum is made up of a many-body system of magnetic charges. A dual Abelian-Higgs model,with a Higgs vacuum constant added has been derived from the gluonic field part of SU(2)QCD based on the Faddeev-Niemi decomposition and random-order assumptions.The scale potential Vhas the Mexico-hat form.

Reefs, reef-mounds and lime mud mounds are all carbonate buildups, and the reefs and banks are important targets for petroleum exploration The reefs, banks and mounds should be divided from each other not only in theory, but also in exploration practice, because of so many differences in sedimentary compositions, fabrics, environments, distribution in time and space, and the characteristics of petroleum geology If the original reef or bank itself was fine reservoir rocks, then it would become a better reservoir after the reservoirconstructive diagenesis The formation of a high quality carbonate reservoir is controlled by two factors: the sedimentary microfacies and the reservoirconstructive diagenesis The first is the basis for the formation of a high quality reservoir, and with the high energy reefbank facies as the best; the latter includes the cataclasis, the dolomitization and the karstification The dolomitization and karstification are the best for the formation of a high quality reservoir The karstification has the widest distribution, profoundest effect, and plays a vital role in the high quality reservoir forming The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, penesedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir The formation mechanism of synsedimentary karst and penesedimentary karst is related to the short time exposing and leaching of the cyclical highfrequency shallowupward sequence when the reefs or banks are forming The supergene karst is controlled by the exposing and leaching of tertiary cyclic sequence type I interface after the reefs or banks forming Thus, there developed a great deal of secondary corrosion pores, corrosion fractures and huge caves besides some original pores remained in the reef and bank reservoir Scarcely there are any original effective pores in reefmounds and lime mud mounds, especially in senkes among mounds, but secondary pores could be formed by karstification, and there would likely develop source rocks with high organic abundance
礁、礁丘、丘同属碳酸盐建隆,礁、滩是重要勘探目的层。但各自在沉积组分、组构、环境和时空分布,以及油气地质条件上迥然不同,因而无论从理论还是勘探实践上,都有必要将其各成体系划分开来。礁滩自身为好储集岩,当建设性成岩作用叠加后可形成好的储层。碳酸盐岩优质储层形成,主要受沉积微相与建设性成岩作用两大因素控制。前者是基础,并以高能的礁滩相带为最好;后者主要包括破裂、白云石化和溶蚀三大类,并以白云石化或溶蚀为最优,其中的溶蚀分布最广泛、影响最深刻而对优质储层形成起决定性作用。礁滩储层中的古岩溶类型最为丰富多彩,包括同生期、准同生期、表生期和埋藏期热流体岩溶的所有类型,白云岩化礁滩体也不例外。其中,同生准同生期岩溶的形成机制与礁滩沉积时高频层序旋回向上变浅序列的短暂暴露淋溶有关,表生期岩溶则受控于礁滩沉积后三级层序旋回Ⅰ型界面的暴露淋溶。由此,导致礁滩储层中除了可以也是唯一保存原生孔隙外,还发育了次生溶蚀孔洞缝和大型溶洞。礁丘、灰泥丘尤其是丘间洼地中发育高有机质丰度烃源岩;它们自身没有有效的原生孔隙,但岩溶作用可以形成次生孔隙。

In chapter 4, the plane-radial and plane-parallel flows for Newtonian fluid in fractal porous media are analyzed. Based on the same assumption as that in chapter 3, the expressions for porosity, flow rate, velocity and permeability for both radial and parallel flows are developed. The proposed expressions are expressed as a function of tortuosity, fractal dimension, maximum and minimum pore diameters, and there are no empirical constant and every parameter has clear physical meaning in the proposed expressions.
