Here, we propose the molecular hybridization of dihydroartemisinin (DHA) and ursodeoxycholic bile acid (UDCA), approved drugs, for the preparation of antiviral agents against SARS-CoV-2. DHA and UDCA were selected on the basis of their recently demonstrated activity against SARS-CoV-2. A selection of DHA-UDCA-based hybrids obtained by varying the nature of the linkage and the bile acid conjugation point as well as unconjugated DHA and UDCA were tested for cytotoxicity and anti-SARS-CoV-2 activity on Vero E6 and Calu-3 human lung cells. The hybrid DHA-t-UDCMe, obtained by conjugation via click chemistry on a gram scale, was identified as a potential candidate for SARS-CoV-2 infection treatment due to significant reduction of viral replication, possibly involving ACE2 downregulation, no cytotoxicity, and chemical stability.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

Unlabelled: SY21 and SY22 exhibit anti-inflammatory activity; however, their safety has not been evaluated. The suitability as probiotic strains were evaluated by using phenotypic and genotypic analyses. Indole production, urease activity, mucin degradation, bile salt hydrolase activity, β-hemolysis, and gelatin liquefaction activity were not found.

Limosilactobacillus fermentum CRL2085, isolated from feedlot cattle rations, displayed high efficiency as a probiotic when administered to animals. A comprehensive genomic analysis was performed to elucidate the genetic basis underlying its probiotic potential. Fifteen genomic islands and CRISPR-Cas elements were identified in its genome.

Pyroptosis is a lytic and pro-inflammatory regulated cell death pathway mediated by pores formed by the oligomerization of gasdermin proteins on cellular membranes. Different pro-inflammatory molecules such as interleukin-18 are released from these pores, promoting inflammation. Pyroptotic cell death has been implicated in many pathological conditions, including cancer and liver diseases.

The incidence of traumatic brain injury (TBI) has demonstrated a marked escalation recently. Nevertheless, there remains a critical paucity of effective drug interventions targeting persistent neuroinflammation-induced damage following TBI. STING/NF-κB axis-induced pyroptosis emerges as a pivotal mechanism driving persistent neuroinflammation, providing it as a potential target for multi-pathway precision therapeutic in TBI.
