Alwafi1,2, Scott Panther2, Angela Lo2, Edwin H. Yen2, Bingshuang Zou2 1Department of Dental Public Health, Faculty of Dentistry, King Abdulaziz University, 2Department of Oral Health Science, Faculty of Dentistry, University of British Columbia This manuscript presents a comprehensive protocol to evaluate the three-dimensional (3D) movement of maxillary posterior teeth with clear aligners using digital model superimposition, an invaluable tool in orthodontics and dentofacial orthopedics. Medicine Comparing Bibliometric Analysis Using PubMed, Scopus, and Web of Science Databases Saif Aldeen S. AlRyalat1, Lna W. Malkawi2, Shaher M. Momani3,4 1Department of Ophthalmology, University of Jordan, 2Department of Radiology and Nuclear Medicine, University of Jordan, 3Dean of Scientific Research, University of Jordan, 4Nonlinear Analysis and Applied Mathematics (NAAM) Research Group, Faculty of Science, King Abdulaziz University Literature databases are commonly used to assess publications in a certain subject, discipline, country, or region of the world, a practice known as bibliometric analysis. The current protocol details how to use PubMed, Scopus, and Web of Science databases to do bibliometric analysis. Engineering Enhanced Electron Injection and Exciton Confinement for Pure Blue Quantum-Dot Light-Emitting Diodes by Introducing Partially Oxidized Aluminum Cathode Zhibin Wang1, Tai Cheng1, Fuzhi Wang1, Yiming Bai1, Xingming Bian1, Bing Zhang1, Tasawar Hayat2,3, Ahmed Alsaedi3, Zhan'ao Tan1 1State Key Laboratory of Alternate Electrical Power System with Renewable Energy Sources, North China Electric Power University, 2Department of Mathematics, Quaid-I-Azam University, 3NAAM Research Group, Faculty of Science, King Abdulaziz University A protocol is presented for fabricating high-performance, pure blue ZnCdS/ZnS-based quantum dots light-emitting diodes by employing an autoxidized aluminum cathode. Immunology and Infection Development of an in vitro model system for studying the interaction of Equus caballus IgE with its high-affinity receptor FcεRI Sari Sabban1, Hongtu Ye2, Birgit Helm2 1Biological Department, King Abdulaziz University, 2The Krebs Institute for Biomolecular Research, Department of Molecular Biology and Biotechnology, The University of Sheffield The current study describes the development and applications of a genetically engineered assay system based on the transfection of rat basophilic leukemia cells with the equine FcεRIα gene. Transfected cells express a functional receptor where the release of mediators of the allergic response can be activated by IgE and antigen. Chemistry Synthesis and Characterization of Functionalized Metal-organic Frameworks Olga Karagiaridi1, Wojciech Bury1,2, Amy A. Sarjeant1, Joseph T. Hupp1, Omar K. Farha1,3 1Department of Chemistry, Northwestern University, 2Department of Chemistry, Warsaw University of Technology, 3Department of Chemistry, Faculty of Science, King Abdulaziz University Synthesis, activation, and characterization of intentionally designed metal-organic framework materials is challenging, especially when building blocks are incompatible or unwanted polymorphs are thermodynamically favored over desired forms. We describe how applications of solvent-assisted linker exchange, powder X-ray diffraction in capillaries and activation via supercritical CO2 drying, can address some of these challenges. Immunology and Infection Quantitative Analyses of all Influenza Type A Viral Hemagglutinins and Neuraminidases using Universal Antibodies in Simple Slot Blot Assays Caroline Gravel*1, Changgui Li*2, Junzhi Wang2, Anwar M Hashem1,3,4, Bozena Jaentschke1, Gary Van Domselaar5, Runtao He5, Xuguang Li1,3 1Centre for Vaccine Evaluation, Biologics and Genetic Therapies Directorate, HPFB, Health canada, 2National Institute for the Control of Pharmaceutical and Biological Products, The State Food and Drug Administration, Beijing, 3Department of Biochemistry, Microbiology and Immunology, University of Ottawa, 4Microbiology Department, Faculty of Medicine, King Abdulaziz University, 5National Microbiology Laboratory, Public Health Agency of Canada A simple slot blot method was developed for the quantification of influenza viral hemagglutinin and neuraminidase using universal antibodies targeting their most conserved sequences identified through bioinformatics analyses. This innovative approach may provide a useful alternative to quantitative determination of all viral hemagglutinin and neuraminidase.
