Матриксины 2, 7 и 9 при раке молочной железы: выяснение возможной связи с концентрацией белка HER-2/neu

The comparative analysis of the quantity of matrix metalloproteinases (MMP) 2,7 and 9 in breast cancer is carried out; the concentration of sex hormones receptors and protein HER-2/neu are determined. Authentically high values MMP-2 and MMP-7 are found in a tumor tissue in contrast to the normal one. The elevated concentration of ММР-2 in a tumor is connected with receptor status (p < 0,05). The highest values of concentration ММР-7 and ММP- 9 are found at RE-, RP- and HER-2/neu + tumors, and also in the tumors with the size more than 4,0 cm.Проведен сравнительный анализ содержания матриксных металлопротеиназ (ММП) 2,7 и 9 в опухолевых тканях молочной железы и гистологически неизмененной ткани, определено содержание рецепторов половых гормонов, белка her-2/neu. Достоверно высокие значения ММП-2 и -7 обнаружены в ткани опухоли по сравнению с гистологически неизмененной тканью. Повышение концентраций ММР 2 в опухоли связано с рецепторным статусом опухоли (p < 0,05). Наиболее высокие значения концентраций ММР-7 и ММР-9 обнаружены при РЭ-, РП- и HER-2/neu+ опухолях, а также в новообразованиях размером более 4,0 см

One particle spectral weight of the three dimensional single band Hubbard model

Dynamic properties of the three-dimensional single-band Hubbard model are studied using Quantum Monte Carlo combined with the maximum entropy technique. At half-filling, there is a clear gap in the density of states and well-defined quasiparticle peaks at the top (bottom) of the lower (upper) Hubbard band. We find an antiferromagnetically induced weight above the naive Fermi momentum. Upon hole doping, the chemical potential moves to the top of the lower band where a robust peak is observed. Results are compared with spin-density-wave (SDW) mean-field and self consistent Born approximation results, and also with the infinite dimensional Hubbard model, and experimental photoemission (PES) for three dimensional transition-metal oxides.Comment: 11 pages, REVTeX, 16 figures included using psfig.sty.
