The Biological Threat Reduction Program, part of the Nunn-Lugar Cooperative Threat Reduction Program since 1991, is mandated by the US Congress to regularly provide public reporting as part of its accountability. The Biological Threat Reduction Program recently designed a metrics and evaluation framework to measure its impact and effectiveness in partner countries. The framework focuses on capacity and capability strengthening related to biosafety, biosecurity, and biosurveillance. This is a marked shift from the previous approach, which relied on more tangible outcomes such as the elimination of weapons of mass destruction production assets, delivery devices, munitions, and construction activities. The new metrics and evaluation framework tracks the program's impact across 24 biosafety, biosecurity, and biosurveillance metrics and numerous capability, capacity, sustainability, and regional leadership indicators for human and animal health systems. The framework uses quantitative and qualitative inputs to generate measurement scores for program investment in partner countries. Overall, the framework provides a robust feedback loop between requirements, plans, and implementation processes throughout each step of the program's annual management lifecycle.

Unlabelled: Avian leukosis virus subgroup J (ALV-J) poses a significant threat to the poultry industry; yet, our understanding of its replication and pathogenic mechanisms is limited. The Ten-Eleven Translocation 2 (TET2) is an indispensable regulatory factor in active DNA demethylation and immune response regulation. This study reports a significant and time-dependent decrease in TET2 levels following ALV-J infection and shows that the reduction of TET2 protein is mediated by the autophagy pathway.

Engineered monoclonal antibodies have proven to be highly effective therapeutics in recent viral outbreaks. However, despite technical advancements, an ability to rapidly adapt or increase antibody affinity and by extension, therapeutic efficacy, has yet to be fully realized. We endeavored to stand-up such a pipeline using molecular modeling combined with experimental library screening to increase the affinity of F5, a monoclonal antibody with potent neutralizing activity against Venezuelan Equine Encephalitis Virus (VEEV), to recombinant VEEV (IAB) E1E2 antigen.

Acinetobacter baumannii stands out for its antimicrobial resistance and high capacity to cause hospital infections, posing a severe threat to global public health. Thus, there is an urgent need for new therapeutic strategies. This work applied photodynamic therapy (PDT) with curcumin to Acinetobacter baumannii, and bacterial cell viability was assessed.

Fungal infections caused by yeast have increased in recent decades, becoming a major threat to public health. Antifungal therapy represents a challenging problem because, in addition to presenting many side effects, fungal resistance has been increasing in recent years. As a result, the search for new therapeutic agents has advanced with the use of new technologies such as nanoparticles (NPs).

The natural vibrational frequencies of biological particles such as viruses and bacteria encode critical information about their mechanical and biological states as they interact with their local environment and undergo structural evolution. However, detecting and tracking these vibrations within a biological context at the single particle level has remained elusive. In this study, we track the vibrational motions of single, unlabeled virus particles under ambient conditions using ultrafast spectroscopy.
