Gastrointestinal bacteria growth inhibition by a toilet sanitary good for disaster shelter.

Japan has experienced several large earthquakes in the past 30 years. Emergency evacuation shelters become overcrowded immediately after disasters. Deteriorating sanitary conditions in toilets are associated with a higher risk of infectious pathogen transmission.

Antibody Responses and Infection Prevention following the Sixth Vaccination using the BA.1 bivalent COVID-19 vaccine among Healthcare workers during the XBB variant Dominance in Japan.

The effect of antibodies elicited by bivalent mRNA vaccines (original and omicron BA.1) on preventing coronavirus disease 2019 (COVID-19) onset in the presence of the XBB variant remains unknown. A prospective cohort study conducted at Chiba University Hospital examined healthcare workers who received their sixth vaccination with the Pfizer-BioNTech COVID-19 bivalent mRNA vaccine (original and omicron BA.

Dynamic diversity of SARS-CoV-2 genetic mutations in a lung transplantation patient with persistent COVID-19.

Numerous SARS-CoV-2 variant strains with altered characteristics have emerged since the onset of the COVID-19 pandemic. Remdesivir (RDV), a ribonucleotide analogue inhibitor of viral RNA polymerase, has become a valuable therapeutic agent. However, immunosuppressed hosts may respond inadequately to RDV and develop chronic persistent infections.

PKR-NF-κB Pathway Upstream of IFN-β Induction Is Dysregulated in Oncolytic Sindbis Virus-infected HeLa Cells.

Background/aim: Sindbis virus (SINV) is a naturally occurring oncolytic virus that kills cancer cells and is less harmful to normal cells. In this study, a recombinant SINV, which expressed green and blue fluorescent proteins, was used to precisely analyze SINV infection and replication.

Materials And Methods: Antiviral responses, including IFN-β mRNA, protein kinase R (PKR), NF-B, and caspase 3/7, were analyzed in SINV-infected cancerous HeLa cells and normal human fibroblast TIG-1-20 cells.

Molecular detection of dengue virus in patients suspected of Ebola virus disease in Ghana.

Dengue fever is known to be one of the most common arthropod-borne viral infectious diseases of public health importance. The disease is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, Southeast Asia and the Western Pacific with an estimated two fifths of the world's population being at risk. The notable endemic viral hemorrhagic fevers (VHFs) found in West Africa, including yellow fever, Lassa fever, Rift Valley fever, dengue fever and until recently Ebola have been responsible for most outbreaks with fatal consequences.
