1单壁碳和多壁碳纳米管内多孔纤毛脉动诱导流体流动的熵分析(英文)显示文摘对均匀磁场和多孔介质作用下水平纤毛管内黏性纳米流体流动的热力学进行分析。另外,对存在内部热源和热辐射的情况也进行了能量分析。加入碳纳米管(CNTs)增强了基流水的热导率。通过公式转换得到一组非线性耦合偏微分方程。通过相似变量的转换,将控制微分系统转化为一个常微分系统。计算了温度、动量和压力梯度分布的封闭形式的精确解。本研究主要研究了碳纳米管的导电性,讨论了不同流线的模式。热力学分析表明,电流系统的熵随着Brinkmann 数、磁性参数、纳米粒子浓度参数和Darcy 数的增大而增大。Muhammad N ABRAR Muhammad SAGHEER Shafqat HUSSIAN 2019Journal of Central South University2019,26,8:3
2Pam3CSK4 enhances adaptive immune responses to recombinant Mycobacterium bovis bacille Calmette-Guérin expressing Plasmodium falciparum C-terminus merozoite surface protein-1显示文摘Objective: To determine the effects of toll-like receptor 2(TLR-2) agonist, Pam3 CSK4, on cellular and humoral immune response against recombinant Mycobacterium bovis bacille Calmette-Guérin(rBCG) expressing the C-terminus of merozoite surface protein-1 of Plasmodium falciparum.Methods: Six groups of mice(n=6 per group) received intraperitoneal phosphate buffered saline T80(PBS-T80), BCG or rBCG in the presence or absence of Pam3 CSK4. Enzymelinked immunosorbent assay was carried out to measure serum total IgG, IgG1, IgG2 a, and Ig G2 b production. Spleens were also harvested and splenocytes were co-cultured with rBCG antigen for in vitro determination of IL-4 and IFN-γ via enzyme-linked immunosorbent assay.Results: The production of total IgG and the isotype IgG1, IgG2 a and IgG2 b was significantly higher in rBCG-immunised mice than in the BCG and PBS-T80-immunised mice, and Pam3 CSK4 further enhanced their productions. A similar pattern was also observed in IFN-γ production. Moreover, there was no significant difference in IL-4 production in all groups either in the presence or absence of Pam3 CSK4.Conclusions: We present evidence of the adjuvant effects of TLR-2 agonist in enhancing the production of total IgG, IgG1, IgG2 a, IgG2 b, as well as IFN-γ in response to rBCG. However, the presence or absence of Pam3 CSK4 had no effect on IL-4 production.Mohamed H Abdikarim Muhammad A Abbas Munirah N Zakaria Robaiza Zakaria Rapeah Suppian 2019Asian Pacific Journal of Tropical Biomedicine2019,9,7:3

4Disparities in colorectal cancer in African-Americans vs Whites: Before and after diagnosis显示文摘There are differences between African-American and white patients with colorectal cancer, concerning their characteristics before and after diagnosis. Whites are more likely to adhere to screening guidelines. This is also the case among people with positive family history. Colorectal cancer is more frequent in Blacks. Studies have shown that that since 1985, colon cancer rates have dipped 20% to 25% for Whites, while rates have gone up for African-American men and stayed the same for African-American women. Overall, African-Americans are 38% to 43% more likely to die from colon cancer than are Whites. Furthermore, it seems that there is an African-American predominance in right-sited tumors. African Americans tend to be diagnosed at a later stage, to suffer from better differentiated tumors, and to have worse prognosis when compared with Whites. Moreover, less black patients receive adjuvant chemotherapy for resectable colorectal cancer or radiation therapy for rectal cancer. Caucasians seem to respond better to standard chemotherapy regimens than AfricanAmericans. Concerning toxicity, it appears that patients of African-American descent are more likely to develop 5-FU toxicity than Whites, possibly because of their different dihydropyridine dehydrogenase status. Last but not least, screening surveillance seems to be higher among white than among black long-term colorectal cancer survivors. Socioeconomic and educational status account for most of these differences whereas little evidence exists for a genetic contribution in racial disparity. Understanding the nature of racial differences in colorectal cancer allows tailoring of screening and treatment interventions.Anastasios Dimou Kostas N Syrigos Muhammad Wasif Saif 2009World Journal of Gastroenterology2009,15,30:2
5在周期性的 glucagonoma 的骨头损害: 一份案例报告和文学的评论显示文摘 Glucagonomas are rare neuroendocrine tumors that arise from cells of the pancreatic islets. Most of them are malignant and usually present as metastatic disease. Sites most commonly involved in metastases are the liver and regional lymph nodes. Bone metastases are rare events and only a few cases have been reported in the literature. We present the case of a 53-year-old male with a medical history of recurrent non-functioning glucagonoma. He presented 17 years after the initial diagnosis with new blastic bone lesions involving the T1 vertebra and the sacrum. Diagnostic steps and medical management in metastatic glucagonoma are also reviewed.Cristian Ghetie Daniel Cornfeld Vassilios S Ramfidis Kostas N Syrigos Muhammad W Saif 2012World Journal of Gastrointestinal Oncology2012,4,6:2

7Structural, electronic, and optical properties of ZnO_(1-x)Se_x alloys using first-principles calculations显示文摘The structural, electronic, and optical properties of binary ZnO, ZnSe compounds, and their ternary ZnO 1-x Se x alloys are computed using the accurate full potential linearized augmented plane wave plus local orbital (FP-LAPW + lo) method in the rocksalt (B1) and zincblende (B3) crystallographic phases. The electronic band structures, fundamental energy band gaps, and densities of states for ZnO 1-x Se x are evaluated in the range 0 ≤ x ≤ 1 using Wu-Cohen (WC) generalized gradient approximation (GGA) for the exchange-correlation potential. Our calculated results of lattice parameters and bulk modulus reveal a nonlinear variation for pseudo-binary and their ternary alloys in both phases and show a considerable deviation from Vegard's law. It is observed that the predicted lattice parameter and bulk modulus are in good agreement with the available experimental and theoretical data. We establish that the composition dependence of band gap is semi-metallic in B1 phase, while a direct band gap is observed in B3 phase. The calculated density of states is described by taking into account the contribution of Zn 3d, O2p, and Se 4s, and the optical properties are studied in terms of dielectric functions, refractive index, reflectivity, and energy loss function for the B3 phase and are compared with the available experimental data.Muhammad Rashid Fayyaz Hussain Muhammad Imran S A Ahmad N A Noor M U Sohaib S M Alay-e-Abbas 2013Chinese Physics B2013,22,8:2
