Roles of flavonoids against coronavirus infection

Chemico-Biological Interactions, 2020
In terms of public health, the 21st century has been characterized by coronavirus pandemics: in 2002-03 the virus SARS-CoV caused SARS; in 2012 MERS-CoV emerged and in 2019 a new human betacoronavirus strain, called SARS-CoV-2, caused the unprecedented COVID-19 outbreak.

Single‐Layer Radially Compartmentalized Paper Chip (RCP‐Chip) for Rapid Isothermal Multiplex Detection of SARS‐CoV‐2 Gene Targets

Advanced Sensor Research, EarlyView.
The single‐layer RCP‐Chip enables rapid, multiplexed detection of SARS‐CoV‐2 RNA using RT‐LAMP and gold nanoparticle‐enhanced colorimetric readouts. After sample loading, amplification occurs within radially arranged chambers, allowing simultaneous detection of E and N genes.

On a quarantine model of coronavirus infection and data analysis [PDF]

arXiv, 2020
Attempts to curb the spread of coronavirus by introducing strict quarantine measures apparently have different effect in different countries: while the number of new cases has reportedly decreased in China and South Korea, it still exhibit significant growth in Italy and other countries across Europe.

DOPE: D-Optimal Pooling Experimental design with application for SARS-CoV-2 screening [PDF]

arXiv, 2021
Testing individuals for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen causing the coronavirus disease 2019 (COVID-19), is crucial for curtailing transmission chains. Moreover, rapidly testing many potentially infected individuals is often a limiting factor in controlling COVID-19 outbreaks.

Dual‐Locking the SARS‐CoV‐2 Spike Trimer: An Amphipathic Molecular “Bolt” Stabilizes Conserved Druggable Interfaces for Coronavirus Inhibition

Advanced Science, EarlyView.
A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.

Predicting potential SARS-CoV-2 spillover and spillback in animals [PDF]

Journal of Microbiology Immunology and Infection, Vol. 57, No. 2, pp. 225-237, 2024
The COVID-19 pandemic is spreading rapidly around the world, causing countries to impose lockdowns and efforts to develop vaccines on a global scale. However, human-to-animal and animal-to-human transmission cannot be ignored, as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread rapidly in farmed and wild animals.

Potent Cross‐neutralizing Antibodies Reveal Vulnerabilities of Henipavirus Fusion Glycoprotein

Advanced Science, EarlyView.
Hendra and Nipah viruses (HNVs) pose significant threats to global health. This work reports potent cross‐neutralizing antibodies targeting the fusion glycoprotein (F) and reveals shared features of these antibodies and vulnerabilities of F, thereby guiding the rational design of countermeasures against HNVs and similar pathogens.

Mercaptophenylboronic Acid‐Mediated Nanozyme Immunochromatographic Assay for Simultaneous Detection of Respiratory Bacteria and Virus

Advanced Science, EarlyView.
This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...

Pyroptosis: Physiological roles in viral infection [PDF]

arXiv, 2020
The current review focuses on important aspects of pyroptosis, such as morphological features of inflammasomes, as well as on knowledge about coronavirus infection mechanisms and the association between SARS-CoV-2 infection and cell pyroptosis. The application of immunomodulation therapies to Covid-19 patients is the most promising treatment under ...

Coronavirus HKU1 Infection in the United States [PDF]

Emerging Infectious Diseases, 2006
In 2005, a new human coronavirus, HCoV-HKU1, was identified in Hong Kong. We screened respiratory specimens collected from December 16, 2001, to December 15, 2002, from children
