nsP2 Protease Inhibitor Blocks the Replication of New World Alphaviruses and Offer Protection in Mice.

New World alphaviruses, including Venezuelan equine encephalitis virus (VEEV), eastern equine encephalitis virus (EEEV), and western equine encephalitis virus (WEEV), are mosquito-transmitted viruses that cause disease in humans. These viruses are endemic to the western hemisphere, and disease in humans may lead to encephalitis and long-term neurological sequelae. There are currently no FDA-approved vaccines or antiviral therapeutics available for the prevention or treatment of diseases caused by these viruses.

Host-Driven Ubiquitination Events in Vector-Transmitted RNA Virus Infections as Options for Broad-Spectrum Therapeutic Intervention Strategies.

Many vector-borne viruses are re-emerging as public health threats, yet our understanding of the virus-host interactions critical for productive infection remains limited. The ubiquitination of proteins, including host- and pathogen-derived proteins is a highly prominent and consistent post-translational modification that regulates protein function through signaling and degradation. Viral proteins are documented to hijack the host ubiquitination machinery to modulate multiple host processes including antiviral defense mechanisms.

Electrostatic capture of viruses on cationic biopolymer membranes for intra-oral disease sampling.

Naso- and oropharyngeal swabs are the Center for Disease Control and Prevention (CDC) -recommended disease sampling methods for respiratory viruses. The short swabbing time for sampling by these methods may lead to variability in test results. Further, these methods are mildly invasive and can cause discomfort, tearing or gag reflexes in tested individuals.

Electrical impedance characterization and modelling of Ti-Β implants.

Commercially pure titanium (c.p. Ti) and Ti6Al4V alloys are the most widely used metallic biomaterials in the biomedical sector.
