MedicalResearch.com: What is the background for this study?
Response: We’ve long known that maternal stress during pregnancy can affect her baby’s development, but the molecular mechanisms behind this remained unclear. In our study, we explored how psychosocial stress experienced by the mother in late pregnancy influences tiny molecular fragments in the newborn’s blood. These fragments, called transfer RNA fragments or tRFs, were considered for many years to be disposable, but have recently been shown to have important biological functions.

MedicalResearch.com: What is the background for this study?
Response: In the early stages of the COVID-19 pandemic, contact and droplet transmission were considered the main routes of infection. However, it was later demonstrated that airborne transmission is an important route. Therefore, accumulating real-world data on airborne transmission was deemed crucial.

MedicalResearch.com: What is the background for this study?
Response: When the Covid-19 virus infects cells, it takes over and redirects our cells resources towards the projection of virus building blocks and new viruses. Building blocks include large amounts of RNAs that encode for the viral proteins, much as the mRNA vaccines direct our bodies to make the spike protein. We wondered how the virus changes cell metabolism in order to support the synthesis of vast amounts of viral RNAs within hours of infection.
