| 1 | Perfusion computed tomography in renal cell carcinoma显示文摘Various imaging modalities are available for the diagnosis, staging and response evaluation of patients with renal cell carcinoma(RCC). While contrast enhanced computed tomography(CT) is used as the standard of imaging for size, morphological evaluation and response assessment in RCC, a new functional imaging technique like perfusion CT(p CT), goes down to the molecular level and provides new perspectives in imaging of RCC. p CT depicts regional tumor perfusion and vascular permeability which are indirect parameters of tumor angiogenesis and thereby provides vital information regarding tumor microenvironment. Also response evaluation using p CT may predate the size criteria used in Response Evaluation Criteria in Solid Tumors, as changes in the perfusion occurs earlier following tissue kinase inhibitors before any actual change in size. This may potentially help in predicting prognosis, better selection of therapy and more accurate and better response evaluation in patients with RCC. This article describes the techniques and role of p CT in staging and response assessment in patients with RCCs. | Chandan J Das Usha Thingujam Ananya Panda Sanjay Sharma Arun Kumar Gupta | 2015 | World Journal of Radiology2015，7，7： | 8 |
| 2 | 环鸟苷酸依赖的蛋白激酶对心血管功能的调节作用显示文摘环鸟苷酸(cGMP)依赖的蛋白激酶(PKG)是一氧化氮-cGMP的主要细胞内受体,在哺乳动物细胞中分为PKG-I和PKG-II两型。在PKG介导的血管平滑肌舒张作用中,其主要通过活化细胞膜上的钙活化的钾通道(BK通道),磷酸化肌质网上的受磷蛋白(phospholamban,PLB)和三磷酸肌醇受体相关的PKG-I底物(IP3receptor-associated PKG-I substrate,IRAG),降低细胞内Ca2+浓度。PKG还可通过活化肌球蛋白轻链磷酸酶及抑制Rho激酶降低肌球蛋白对Ca2+敏感性。PKG调节血管平滑肌细胞的基因表达和表型调变,调节细胞增生。PKG活化以后还具有抑制血小板聚集,抑制心肌细胞肥大等功能。最近的研究证明,PKG的表达水平和活性改变与动脉粥样硬化和再狭窄、高血压、糖尿病心血管病变以及硝酸盐耐受等的发病机制有密切关系。 | 王晓华 童梅 窦豆 Usha J Raj 高远生 | 2005 | 生理科学进展2005，36，4： | 7 |

| 10 | Local sum uncertainty relations for angular momentum operators of bipartite permutation symmetric systems显示文摘We show that violation of the variance based local sum uncertainty relation(LSUR)for angular momentum operators of a bipartite system,proposed by Hofmann and Takeuchi[Phys.Rev.A 68032103(2003)],reflects entanglement in the equal bipartitions of an N-qubit symmetric state with even qubits.We establish the one-to-one connection with the violation of LSUR with negativity of covariance matrix[Phys.Lett.A 364203(2007)]of the two-qubit reduced system of a permutation symmetric N-qubit state. | I Reena H S Karthik J Prabhu Tej Sudha A R Usha Devi A K Rajagopal | 2022 | Chinese Physics B2022，31，6： | 1 |
