CXC family of chemokines as prognostic or predictive biomarkers and possible drug targets in colorectal cancer

Colorectal cancer(CRC) is the third most common cancer in men and the second most common cancer in women,worldwide. In the early stages of the disease, biomarkers predicting early relapse would improve survival *** metastatic patients, the use of predictive biomarkers could potentially result in more personalized treatments and better outcomes. The CXC family of chemokines(CXCL1 to 17) are small(8 to 10 kDa) secreted proteins that attract neutrophils and lymphocytes. These chemokines signal through chemokine receptors(CXCR) 1 to *** studies have reported that these chemokines and receptors have a role in either the promotion or inhibition of cancer, depending on their capacity to suppress or stimulate the action of the immune system, *** general terms, activation of the CXCR1/CXCR2 pathway or the CXCR4/CXCR7 pathway is associated with tumor aggressiveness and poor prognosis; therefore,the specific inhibition of these receptors is a possible therapeutic strategy. On the other hand, the lesser known CXCR3 and CXCR5 axes are generally considered to be tumor suppressor signaling pathways, and their stimulation has been suggested as a way to fight *** pathways have been studied in tumor tissues(using immunohistochemistry or measuring mRNA levels)or serum [using enzyme-linked immuno sorbent assay(ELISA) or multiplexing techniques], among other sample types. Common variants in genes encoding for the CXC chemokines have also been investigated as possible biomarkers of the disease. This review summarizes themost recent findings on the role of CXC chemokines and their receptors in CRC and discusses their possible value as prognostic or predictive biomarkers as well as the possibility of targeting them as a therapeutic strategy.

The extractable hydrokinetic power from an oscillating membrane-based harvester

引用

Theoretical & Applied Mechanics Letters 2019年第2期9卷 66-70页

作者： Francisco J.Arias Salvador de las heras department of Fluid Mechanics University of Catalonia

The extractable hydrokinetic power from an oscillating membrane in standing motion and induced by a water flow and its possible significance with regard energy harvesting is *** main attractiveness of such an energy harvester lies in the possibility of an inexpensive technology able to be used in those water flows which either because limitation of space(narrow channels) or a limited differential pressure drop with the surrounding but yet with a non negligible velocity are not well suited to be turbined. Utilizing a simplified geometrical model, an estimate of the extractable output density power per area of membrane was derived. Preliminary experiments were performed using a rectangular thin rubber membrane and for a typical domestic water intake as source. The experimental data quantitatively agree very well with the theoretical prediction where it was found that for water flows around 2 m/s the output power density from the membrane may be around 30 mW/cm^2 of membrane. Additional research and development is required in order to arrive at a reliable practical and commercial design.

geochemistry of a Tidal Transgressive Heterolithic Succession: The Ituzaingó Formation (Middle Miocene), Argentina

引用

Chinese Journal Of geochemistry 2000年第1期19卷 52-57页

作者： ROBERTO TORRA (Centro de geociencias Aplicadas, Universidad Nacional del Nordeste. Avda. las heras 727, 3500, RESISTENCIA, Chaco, Argentina) Centro de geociencias Aplicadas Universidad National del Nordeste. Avda Resistencia Argentina

geochemical analysis by means of XRF and ICP\|AES was carried out on 35 selected samples. Major and trace elements were determined. They were: CaCO\-3, P\-2O\-5, Fe\-2O\-3, TiO\-2, SiO\-2, Al\-2O\-3, CaO, K\-2O, MnO, Rb, Cs, ga, Zr, Ta, Nb, Sr, Ba, Cr, Ni, Zn, Pb, Cu, V and B. The country rocks studied were of sandy\|muddy lithofacies, belonging to a typical tide marine transgressive heterolithic succession of Middle Miocene age. They are called the Ituzaingó Formation. The formation outcrops in northeastern Argentina on the left of the Paraná River Valley. The depositional setting largely depends on the outstanding internal structures and textures (i.e., herringbone cross stratification, tidal bundles, reactivation surfaces). In the study area, loessial friable sediment was used as geochemical background because it overlies shallow marine sediments. The results show significant differences. Boron is absent in loessial sediments. On the other hand, several trace elements such as vanadium and chromium are concentrated in the shallow marine sediments. These results may be useful to discern uncertain beds in the area studied.

EFFECT OF FOSSIL DIATOMS ON THE gROWTH OF TWO SYNgENEIC MURINE LEUKEMIAS

引用

Chinese Journal of Oceanology and Limnology 1984年第2期2卷 161-167页

作者： Oscar D. Bustuoabad and Alejandro M. S. Mayer(PLEX-CONICET, Institute de Investigaciones Hematoldgicas, Academia Nacional de Medicina, las heras 3092, 1425 Buenos Aires, Argentina) 1. Plex-Conicet Instituto de Investigaciones Hematológicas Academia Nacional de Medicina Las Heras 3092 1425 Buenos Aires Argentina

The effect of micronized frustules. of fossil diatoms (DS) on tumor growth and survival of mice receiving an ip inoculations of either a spontaneous lymphoblastic leukemia (LB) or P-388 lymphocyt-ic leukemia (P-388) was investigated. A multi-dose study was designed, mice receiving 1000,100,10 arid 1 μg of a suspension of DS, either ip or sc on day 1, 4 and 9 after tumor inoculation. With LB the best results were observed when DS were inoculated by the ip route, no effect being observed with the sc route. The best therapeutic effect resulted with 1 μg DS: 33 % of the mice were alive 24 days after tumor inoculation, when all the controls had died. With P-388, only a temporary effect with the 10 μg DS dose was. observed. In no case was it possible to prolong survival. It is concluded that at low doses of DS therapeutic effect is greatest, while toxicity due to SiO2 is greatly reduced.
