Summary: This study evaluated the lipidomic profile of rice bran from the Italian rice variety, Roma, using ultra performance liquid chromatography-tandem mass spectrometry. Ethanol and methyl tert-butyl ether/methanol solvents were found to be excellent solvents for lipid extraction from rice bran, with ethanol being the most effective for triglycerides and N-acylethanolamines, and methyl tert-butyl ether/methanol being the most effective for diglycerides, phospholipids, and ceramides. Additionally, extraction with ethanol at 20 degrees C yielded similar results to extraction at 4 degrees C. Therefore, ethanol and methyl tert-butyl ether/methanol can be used to efficiently extract lipids from rice bran, contributing to the valorization of this by-product in a circular economy perspective.

Summary: This study reports a simple method to achieve active terahertz (THz) absorption performance using ethanol-treated carbon nanotube sponges (CNT-Sponges). The single CNT-Sponges show high electromagnetic interference shielding effectiveness and can absorb over 80% of the electromagnetic energy from 0.2 THz to 1.0 THz. Spraying ethanol on the CNT-Sponges results in decreased absorption, which can recover over time due to the change in ethanol content.

Summary: This study examines the molecular evolution of the IFN epsilon pseudogene in Manis javanica and its role in modulating the innate and specific antiviral immunity in this species. It finds evidence of positive selection in the human and primate IFN epsilon genes, suggesting their importance in the evolution of the immune system. Comparative genomic analysis reveals that the IFN epsilon pseudogene in pangolins originated from a gene duplication event and has lost its protein-coding function, but it may still play a regulatory role in antiviral immunity.
