To understanding the epidemiological role of camels in the transmission of MERS-CoV, we utilized an iterative empiri...
Chapter 4 Molecular Modeling of Major Structural Protein Genes of Avian Coronavirus: Infectious Bronchitis Virus Mass H120 and Italy02 Strains
Abstract In Morocco, the epidemiological situation of infectious bronchitis virus (IBV) is very complex, because of the antigenic diversity associated with the emergence of new serotypes/genotypes and variants. The IBV strains circulating in poultry farms are serotypes/genotypes Italy02 and Massachusetts (Mass) identif...
10 “C” in COVID19
World war “C”(1) has set in against an invisible virus. The routes of transmission include *Contact of contaminated objects,*Circulating droplets in the air called aerosols disseminated through *Cough, sneeze, ocular secretions(2) from an infected individual.
SARS-CoV-2 and SARS-CoV Spike-RBD Structure and Receptor Binding Comparison and Potential Implications on Neutralizing Antibody and Vaccine Development
SARS-CoV-2 and SARS-CoV share a common human receptor ACE2. Protein-protein interaction structure modeling indicates that spike-RBD of the two viruses also has similar overall binding conformation and binding free energy to ACE2. In vitro assays using recombinant ACE2 proteins and ACE2 expressing cells confirmed the tw...
Reshaping ophthalmology training after COVID-19 pandemic
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on practical activities and didactic teaching of residents and fellows. This survey aimed to propose long-term changes for ophthalmology training based on the changes experienced by trainees and their perception of new training op...
Differential proteomic analysis of virus-enriched fractions obtained from plasma pools of patients with dengue fever or severe dengue
BACKGROUND: Dengue is the most widespread mosquito-borne viral disease of public health concern. In some patients, endothelial cell and platelet dysfunction lead to life-threatening hemorrhagic dengue fever or dengue shock syndrome. Prognostication of disease severity is urgently required to improve patient management....
