The COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 has highlighted the critical need for safe and effective vaccines. In this study, subunit nanovaccine formulations were developed using the receptor-binding domain (RBD) of the SARS-CoV-2 spike (S) protein encapsulated in polymeric nanoparticles composed of poly(ethylene glycol)-block-poly(ε-caprolactone) (PEG-PCL). Two surfactants, poly(vinyl alcohol) (PVA) and sodium cholate (SC), were evaluated during formulation via a modified water-in-oil-in-water (w/o/w) emulsion-solvent evaporation method.

Plasmalogens are a subclass of glycerophospholipids characterized by a vinyl-ether bond at the sn-1 position; they play several physiological roles including membrane stabilization, antioxidant activity, and signal transduction. While choline, ethanolamine, serine, and glycerol plasmalogens (PlsCho, PlsEtn, PlsSer, and PlsGro) are naturally abundant, inositol plasmalogens (PlsIns) are rare. In contrast to the limited occurrence of PlsIns, phosphatidylinositol is a biologically crucial lipid, and its enzymatic biosynthesis from phosphatidylcholine has been extensively studied.

The esterase gene encoding EstJN1 of Clostridium butyricum, which was isolated from the pit cellar of Chinese liquor facility, was expressed. EstJN1 was identified as a novel GDSL esterase belonging to family II. The enzyme demonstrated a marked substrate preference for p-nitrophenyl butyrate, with optimal activity at a temperature of 40 ℃ and a pH of 7.

Apicomplexan AP2 (ApiAP2) family proteins are a family of transcription factors that are known to regulate gene expression in apicomplexan pathogens, including . In this study, we focused on TgAP2X-7, a member of the APiAP2 family that is predicted to be essential for fitness. Endogenous tagging of TgAP2X-7 followed by immunofluorescence analysis revealed that it's a cell cycle-regulated nuclear protein with peak expression in the G1 phase.

Oxidative stress induces a wide range of cellular damage, often causing disease and cell death. While many organisms are susceptible to the effects of oxidative stress, haloarchaea have adapted to be highly resistant. Several aspects of the haloarchaeal oxidative stress response have been characterized; however, little is known about the impacts of oxidative stress at the translation level.
