The Maintenance of outer membrane (OM) Lipid Asymmetry system mediates retrograde phospholipid transport from the OM to the inner membrane (IM) in Gram-negative bacteria. However, the interactions between the various subunits of the IM and OM complexes are not well understood. In a recent study in 2023 by MacRae et al. in the Journal of Biological Chemistry, the authors examine components in the Maintenance of OM Lipid Asymmetry complex, define the interaction interfaces between members of the pathway, and propose a molecular model of the lipid transfer process from the OM to the IM that will help elucidate intricacies of lipid transport.

Background: Edible oils are susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs) throughout production, storage, and transportation processes due to their lipophilic nature. The necessity of quantifying PAHs present in complex oil matrices at trace levels, which bind strongly to impurities in oil matrices, poses a major challenge to the accurate quantification of these contaminants. Therefore, the development of straightforward and effective methods for the separation and enrichment of PAHs in oil samples prior to instrumental analysis is paramount to guaranteeing food safety.

Rheumatoid arthritis is a highly prevalent debilitating condition linked to inflammation. The effectiveness of the present therapeutic techniques is constrained; so, there is an urgent requirement for a novel nanoplatform entailing drugs with proven efficacy. The current work highlighted the development of dexamethasone and luteolin co-encapsulated hyalurosomes (LUT-DEX hyalurosomes).

Article Synopsis
- Recent research indicates that blocking the RIPK1/RIPK3/MLKL necrosome can help reduce inflammatory pain linked to conditions like demyelination in the central nervous system.
- This study tests necrostatin-1s (Nec-1s), a specific RIPK1 inhibitor, on LPS-induced inflammatory pain in male mice, assessing pain sensitivity through hot plate tests and examining related protein changes.
- Results show that Nec-1s not only prevents LPS-induced pain relief but also reverses the activation of key proteins and signals involved in inflammation and demyelination, suggesting that RIPK1 inhibitors could be a promising treatment for managing inflammatory pain.

Brown adipose tissue (BAT) is an ideal target organ for obesity treatment. Resinacein S is extracted from Ganoderma lucidum and can elevate Uncoupling protein 1 (UCP1) in cells, but its related effects at the animal level are not clear. The mice were fed with high-fat diet to construct obesity models and treated with Resinacein S.

Applying nano-delivery systems for phytohormones via foliar application has proven effective in reducing grain cadmium (Cd) levels in crops. However, the mechanisms underlying this reduction remain inadequately understood. This study integrated the determination of leaf photosynthetic parameters, Cd translocation analysis, and metabolomics to elucidate the effects of reduced glutathione (GSH) and melatonin (MT), delivered with or without chitosan-encapsulated mesoporous silica nanoparticles (MSN-CS), on grain Cd levels in rice.
