A series of bismuth complexes were synthesized and characterized, and most of them exhibited inhibition against the SARS coronavirus helicase ATPase and duplex-unwinding activities at micromolar concentrations.
Background: The negative impacts of the Coronavirus Disease 2019 (COVID-19)outbreak on public mental health are enhancing the number of individuals requiring psychotherapy. Besides, anxiety is becoming more frequent than any other mental health issue among individuals. Similar to other anxiety types, coronavirus anxiety is associated with elevated attentional bias. The present study aimed to ex...
Background: Organizational success depends on leadership style. Leadership style probably affects coronavirus anxiety and workers’ safety behavior at work. This study aims to examine the structural association between leadership style and coronavirus anxiety with safety behavior among workers in the sanitary products industry in Qom Province. Materials & Methods: This descriptive-correlative s...
Members of the family Coronaviridae have the largest genomes of all RNA viruses, typically in the region of 30 kilobases. Several coronaviruses, such as Severe acute respiratory syndrome-related coronavirus (SARS-CoV) and Middle East respiratory syndrome-related coronavirus (MERS-CoV), are of medical importance, with high mortality rates and, in the case of SARS-CoV, significant pandemic potent...
Viral infections have caused various diseases and deaths worldwide. In recent years, the emergence of the coronavirus has caused severe respiratory tract infections and led to a global concern. This study aims to investigate the effectiveness of various disinfectants that have been used to control the coronavirus. Methods: The present study is a systematic review. Data was collected through sea...
The N7-methylguanosine (m7G) cap is the defining structural feature of eukaryotic mRNAs. Most eukaryotic viruses that replicate in the cytoplasm, including coronaviruses, have evolved strategies to cap their RNAs. In this report, we used a yeast genetic system to functionally screen for the cap-forming enzymes encoded by severe acute respiratory syndrome (SARS) coronavirus and identified the no...
BACKGROUND The widespread threat of severe acute respiratory syndrome (SARS) to human life has spawned challenges to develop fast and accurate analytical methods for its early diagnosis and to create a safe antiviral vaccine for preventive use. Consequently, we thoroughly investigated the immunoreactivities with patient sera of a series of synthesized peptides from SARS-coronavirus structural p...
This is the first report of the isolation of a coronavirus from elk calves. Two fecal samples from elk calves with diarrhea were shown to be positive for coronavirus-like particles by electron microscopy, and the particles were propagated in the human rectal tumor-18 cell line. After 24 h, syncytia were observed, and cell culture supernatants from both samples showed hemagglutinating activity w...
Coronaviruses raise serious concerns as emerging zoonotic viruses without specific antiviral drugs available. Here we screened a collection of 16671 diverse compounds for anti-human coronavirus 229E activity and identified an inhibitor, designated K22, that specifically targets membrane-bound coronaviral RNA synthesis. K22 exerts most potent antiviral activity after virus entry during an early ...
BACKGROUND A new betacoronavirus-Middle East respiratory syndrome coronavirus (MERS-CoV)-has been identified in patients with severe acute respiratory infection. Although related viruses infect bats, molecular clock analyses have been unable to identify direct ancestors of MERS-CoV. Anecdotal exposure histories suggest that patients had been in contact with dromedary camels or goats. We investi...
