*FREE* Four billion people in low- and middle-income countries lack safe drinking water

A new geospatial analysis reveals that only one-third of the world's population in low- and middle-income countries has access to safe drinking water, with fecal contamination affecting almost half. The study emphasizes the need for improved water quality monitoring and infrastructure investments to address this critical human right.

Researchers uncover a mechanism for propagation of flaviviruses

A recent study identified a protein named importin-7 (IPO7) as a carrier that transports flavivirus core proteins into host cell nuclei. The study found that IPO7 plays a crucial role in the efficient production of viral particles, even though initial replication was comparable between two cell types. Blocking this transport mechanism ...

Enhanced expression of two ISGs as potential biomarkers of prognosis in HIV-infected immunological non-responders

Researchers found that HIV-infected individuals with impaired immune recovery (INRs) have significantly higher expression of IFI27 and IFI6 in their peripheral blood compared to those who recovered well (IRs). A predictive model using these genes, along with age and CD4+ T/CD8+ T ratio, accurately identified INRs. These findings sugges...
