Development of a water-dispersible antimicrobial lipid mixture to inhibit African swine fever virus and other enveloped viruses.

Medium-chain antimicrobial lipids are promising antiviral agents to inhibit membrane-enveloped viruses such as African swine fever virus (ASFV) and influenza A virus (IAV) in livestock applications. However, current uses are limited to feed pathogen mitigation due to low aqueous solubility and the development of water-dispersible lipid formulations is needed for broader application usage. In this study, we report a water-dispersible antimicrobial lipid mixture of monoglycerides and lactylates that can inhibit ASFV and IAV and exhibits antiviral properties in drinking water and feed matrices.

Accelerating evidence generation: Addressing critical challenges and charting a path forward.

Efficient evidence generation to assess the clinical and economic impact of medical therapies is critical amid rising healthcare costs and aging populations. However, drug development and clinical trials remain far too expensive and inefficient for all stakeholders. On October 25-26, 2023, the Duke Clinical Research Institute brought together leaders from academia, industry, government agencies, patient advocacy, and nonprofit organizations to explore how different entities and influencers in drug development and healthcare can realign incentive structures to efficiently accelerate evidence generation that addresses the highest public health needs.

IFN-γ and IL-10 Immunosensor with Vertically Aligned Carbon Nanotube Interdigitated Electrodes toward Pen-Side Cattle Paratuberculosis Monitoring.

Highly sensitive vertically aligned carbon nanotube arrays (VANTAs) interdigitated electrode (IDE) arrays are developed for electrochemical biosensing of two cytokines (i.e., interleukin-10 (IL-10) and interferon-gamma (IFN-γ)) that are useful for early detection Johne's disease (Bovine Paratuberculosis) in cattle.

Thg1 family 3'-5' RNA polymerases as tools for targeted RNA synthesis.

Members of the 3'-5' RNA polymerase family, comprised of tRNA guanylyltransferase (Thg1) and Thg1-like proteins (TLPs), catalyze templated synthesis of RNA in the reverse direction to all other known 5'-3' RNA and DNA polymerases. The discovery of enzymes capable of this reaction raised the possibility of exploiting 3'-5' polymerases for posttranscriptional incorporation of nucleotides to the 5'-end of nucleic acids without ligation, and instead by templated polymerase addition. To date, studies of these enzymes have focused on nucleotide addition to highly structured RNAs, such as tRNA and other noncoding RNAs.

Hepato-pancreato-biliary surgery in West Africa: a timely capacity assessment.

Background: West Africa has among the highest rates of hepato-pancreato-biliary (HPB) malignancies in the world. Although surgery is critical for treatment, the availability of HPB surgery in Africa is unknown. This cross-sectional study investigated the current HPB surgical capacity of West African hospitals.
