Two techniques for increasing adsorption of SARS-CoV-2 spike protein to nonwoven polypropylene used in over-the-counter face masks.

Severe acute respiratory syndrome (SARS) is a serious and fatal infectious disease caused by SARS coronavirus (SARS-Cov), a novel human coronavirus. SARS-Cov infection stimulates cytokines (e.g., IL-10, IFN-gamma, IL-1, etc.) expression dramatically, and T lymphocytes and their subsets CD4(+) and CD8(+) T cells are decreased after onset of the disease. SARS-specific IgG antibody is generated in...

BACKGROUND Bovine coronavirus is a primary cause of neonatal calf diarrhea worldwide, and is also associated with acute diarrhea in adult cattle during the winter season. There are no reports on molecular characterization of bovine coronavirus in Ireland, and little data exists apart from serological studies. FINDINGS In this study, 11 neonatal (mean age 9 days) calf BCoV strains from the sou...

Severe acute respiratory syndrome (SARS) is a deadly form of pneumonia caused by a novel coronavirus, a viral family responsible for mild respiratory tract infections in a wide variety of animals including humans, pigs, cows, mice, cats, and birds. Analyses to date have been unable to identify the precise origin of the SARS coronavirus. We used Bayesian, neighbor-joining, and split decompositio...

The recombinant antibodies AQ806, AS739, AT693, AU197 and AU734 detect by flow cytometry the spike S protein from SARS-CoV-2.

Using COVID-19 viral mimicking particles, researchers determine temperature does not impact the spike protein structure or interaction with lung cells

Evolutionary Analysis of Mammalian ACE2 and the Key Residues Involved in Binding to Spike Protein Revealed Potential SARS-CoV-2 Hosts

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...
