1Use of a combination strategy to improve neuroprotection and neuroregeneration in a rat model of acute spinal cord injury显示文摘Spinal cord injury is a very common pathological event that has devastating functional consequences in patients. In recent years, several research groups are trying to find an effective therapy that could be applied in clinical practice. In this study, we analyzed the combination of different strategies as a potential therapy for spinal cord injury. Immunization with neural derived peptides(INDP), inhibition of glial scar formation(dipyridyl: DPY), as well as the use of biocompatible matrix(fibrin glue: FG) impregnated with bone marrow mesenchymal stem cells(MSCs) were combined and then its beneficial effects were evaluated in the induction of neuroprotection and neuroregeneration after acute SCI. Sprague-Dawley female rats were subjected to a moderate spinal cord injury and then randomly allocated into five groups: 1) phosphate buffered saline; 2) DPY; 3) INDP + DPY; 4) DPY+ FG; 5) INDP + DPY + FG + MSCs. In all rats, intervention was performed 72 hours after spinal cord injury. Locomotor and sensibility recovery was assessed in all rats. At 60 days after treatment, histological examinations of the spinal cord(hematoxylin-eosin and Bielschowsky staining) were performed. Our results showed that the combination therapy(DPY+ INDP + FG+ MSCs) was the best strategy to promote motor and sensibility recovery. In addition, significant increases in tissue preservation and axonal density were observed in the combination therapy group. Findings from this study suggest that the combination theapy(DPY+ INDP + FG + MSCs) exhibits potential effects on the protection and regeneration of neural tissue after acute spinal cord injury. All procedures were approved by the Animal Bioethics and Welfare Committee(approval No. 178544; CSNBTBIBAJ 090812960)on August 15, 2016.Elisa García Roxana Rodríguez-Barrera Vinnitsa Buzoianu-Anguiano Adrian Flores-Romero Emanuel Malagón-Axotla Marco Guerrero-Godinez Estefanía De la Cruz-Castillo Laura Castillo-Carvajal Monserrat Rivas-Gonzalez Paola Santiago-Tovar Ivis Morales Cesar Borlongan Antonio Ibarra 2019Neural Regeneration Research2019,14,6:6
2针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) 2020英国医学杂志中文版2020,23,9:5
3Sustaining the gains made in malaria control and elimination显示文摘Significant progress has been made in the last 25 years to reduce the malaria burden,but considerable challenges remain.These gains have resulted from large investments in a range of control measures targeting malaria.Fana and co-authors find a strong relationship between education level and net usage with malaria parasitemia in pregnant women,suggesting the need for targeted control strategies.Mayala and co-workers find important links between agriculture and malaria with implications for inter-sectoral collaboration for malaria control.Randall A Kramer Adriane Lesser 2015Infectious Diseases of Poverty2015,4,1:4
4Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim 2009World Journal of Gastroenterology2009,15,11:4
5A techno-economic and life cycle assessment for the production of green methanol from CO_(2): catalyst and process bottlenecks显示文摘The success of catalytic schemes for the large-scale valorization of CO_(2) does not only depend on the development of active,selective and stable catalytic materials but also on the overall process design.Here we present a multidisciplinary study(from catalyst to plant and techno-economic/lifecycle analysis)for the production of green methanol from renewable H2 and CO_(2).We combine an in-depth kinetic analysis of one of the most promising recently reported methanol-synthesis catalysts(InCo)with a thorough process simulation and techno-economic assessment.We then perform a life cycle assessment of the simulated process to gauge the real environmental impact of green methanol production from CO_(2).Our results indicate that up to 1.75 ton of CO_(2) can be abated per ton of produced methanol only if renewable energy is used to run the process,while the sensitivity analysis suggest that either rock-bottom H2 prices(1.5$kg1)or severe CO_(2) taxation(300$per ton)are needed for a profitable methanol plant.Besides,we herein highlight and analyze some critical bottlenecks of the process.Especial attention has been paid to the contribution of H2 to the overall plant costs,CH4 trace formation,and purity and costs of raw gases.In addition to providing important information for policy makers and industrialists,directions for catalyst(and therefore process)improvements are outlined.Tomas Cordero-Lanzac Adrian Ramirez Alberto Navajas Lieven Gevers Sirio Brunialti Luis MGandía Andrés T.Aguayo S.Mani Sarathy Jorge Gascon 2022Journal of Energy Chemistry2022,31,5:3
6Is there a role for systemic targeted therapy after surgical treatment for metastases of renal cell carcinoma?显示文摘Metastatic renal cell carcinoma(m RCC) is a challenging disease. Despite the new targeted therapies, complete remissions occur only in 1%-3% of the cases, and the most effective first-line treatment drugs have reached a ceiling in overall survival(ranging from 9 to 49 mo). Metastasectomy remains to be the only curative option in most patients with m RCC. Prognostic nomograms have been recently published, so we have tools to classify patients in risk groups, allowing us to detect the cases with the higher risk of recurrence after metastasectomy. Although sparse, there is some evidence of effectiveness of neoadjuvant targeted therapy before metastasectomy; but with an increase in surgical complications due to the effects of these new drugs in tissue healing. We have aimed to answer the question: Is there a role for systemic targeted therapy after surgical treatment for metastases of renal cell carcinoma? We have made a search in Pubmed database. As far as we know, evidence is low and it's based in case reports and small series of patients treated with adjuvant drugs after neoadjuvant therapy plus metastasectomy in cases of partial response to initial systemic treatment. Despite the limitations and high risk of bias, promising results and cases with longterm survival with this approach have been described. Two ongoing clinical trials may answer the question that concerns us.Adrian Husillos Alonso Manuel Carbonero García Carmen González Enguita 2015World Journal of Nephrology2015,4,2:3

11Interaction between castanospermine an immunosuppressant and cyclosporin A in rat cardiac transplantation显示文摘AIM: To investigate the interaction between castanospermine and cyclosporin A(Cs A) and to provide an explanation for it.METHODS: The alkaloid castanospermine was prepared from the seeds of Castanospermum austral consistently achieving purity. Rat heterotopic cardiac transplantation and mixed lymphocyte reactivity were done using genetically inbred strains of PVG(donor) and DA(recipient). For the mixed lymphocyte reaction stimulator cells were irradiated with 3000 rads using a linear accelerator. Cyclosporin A was administered by gavage and venous blood collected 2 h later(C_2). The blood levels of Cs A(Neoral) were measured by immunoassay which consisted of a homogeneous enzyme assay(EMIT) on Cobas Mira. Statistical analyses of interactions were done by an acceleratedfailure time model with Weibull distribution for allograft survival and logistic regression for the mixed lymphocyte reactivity.RESULTS: Castanospermine prolonged transplant survival times as a function of dose even at relatively low doses. Cyclosporin A also prolonged transplant survival times as a function of dose particularly at doses above 2 mg/kg. There were synergistic interactions between castanospermine and Cs A in the prolongation of cardiac allograft survival for dose ranges of Cs A by castanospermine of(0 to 2) mg/kg by(0 to 200) mg/kg(HR = 0.986; 95%CI: 0.981-0.992; P < 0.001) and(0 to 3) mg/kg by(0 to 100) mg/kg(HR = 0.986; 95%CI: 0.981-0.992; P < 0.001) respectively. The addition of castanospermine did not significantly increase the levels of cyclosporin A on day 3 or day 6 for all doses of Cs A. On the contrary, cessation of castanospermine in the presence of Cs A at 2 mg/kg significantly increased the Cs A level(P = 0.002). Castanospermine inhibited mixed lymphocyte reactivity in a dose dependent manner but without synergistic interaction. CONCLUSION: There is synergistic interaction between castanospermine and Cs A in rat cardiac transplantation. Neither the mixed lymphocyte reaction nor the metabolism of Cs A provides an explanation.Adrian D Hibberd David A Clark Paul R Trevillian Patrick Mcelduff 2016World Journal of Transplantation2016,6,1:2
