Human ACE2 transgenic pigs are susceptible to SARS-CoV-2 and develop COVID-19-like disease.

Animal models that accurately reflect COVID-19 are vital for understanding mechanisms of disease and advancing development of improved vaccines and therapeutics. Pigs are increasingly recognized as valuable models for human disease due to their genetic, anatomical, physiological, and immunological similarities to humans, and they present a more ethically viable alternative to non-human primates. However, pigs are not susceptible to SARS-CoV-2 infection which limits their utility as a model.

Client experiences of a task-shifting supported self-management intervention for depression in Vietnam.

Background: The global burden of mental illness is substantial, with depression impacting close to 300 million people worldwide. This has been exacerbated within the context of the COVID-19 pandemic. Yet, in many low- and middle-income countries including Vietnam, there is a substantial treatment gap, with many requiring mental health care unable to access it.

Waveguide-Enhanced Nanoplasmonic Biosensor for Ultrasensitive and Rapid DNA Detection.

DNA is fundamental for storing and transmitting genetic information. Analyzing DNA or RNA base sequences enables the identification of genetic disorders, monitoring gene expression, and detecting pathogens. Traditional detection techniques like polymerase chain reaction (PCR) and next-generation sequencing (NGS) have limitations, including complexity, high cost, and the need for advanced computational skills.
