Production of docosahexaenoic acid by a novel isolated Aurantiochytrium sp. 6-2 using fermented defatted soybean as a nitrogen source for sustainable fish feed development
Biosci Biotechnol Biochem. 2024 Mar 22:zbae035. doi: 10.1093/bbb/zbae035. Online ahead of print.ABSTRACTWe focused on the production of DHA-containing microbial lipids by Aurantiochytrium sp. using of defatted soybean (DS) as a nitrogen source. DS is a plant biomass that could provide a sustainable supply at a low cost. Results showed that Aurantiochytrium sp. could not directly assimilate the DS as a nitrogen source but could grow well in a medium containing DS fermented with rice malt. When cultivated in a fermented DS (FDS) medium, Aurantiochytrium sp. showed vigorous growth with the addition of sufficient sulfate and c...

Pacemaking in the lymphatic system
J Physiol. 2024 Mar 23. doi: 10.1113/JP284752. Online ahead of print.ABSTRACTLymphatic collecting vessels exhibit spontaneous phasic contractions that are critical for lymph propulsion and tissue fluid homeostasis. This rhythmic activity is driven by action potentials conducted across the lymphatic muscle cell (LMC) layer to produce entrained contractions. The contraction frequency of a lymphatic collecting vessel displays exquisite mechanosensitivity, with a dynamic range from <1 to >20 contractions per minute. A myogenic pacemaker mechanism intrinsic to the LMCs was initially postulated to account for pressure-depe...

Structure-Property Relationships for Potential Inversion from Electron Acceptors Based on Thiophene-Fused Triptycene Quinones, 1,4-Diketones and their Malononitrile Adducts
Chemistry. 2024 Mar 22:e202400782. doi: 10.1002/chem.202400782.

This has yielded insights into structure-property relationships for establishing and modulating simultaneous two electron reduction processes in TCAQ analogues. These new compounds were synthesised using a Friedel-Crafts acylation between triptycene and thiophene-3,4-dicarbonyl chloride. Isomeric para-quinones featuring a [c]-fused thiop...

Biosynthesis of Strained Amino Acids by a PLP-Dependent Enzyme through Cryptic Halogenation
Angew Chem Int Ed Engl. 2024 Mar 22:e202319344. doi: 10.1002/anie.202319344. Online ahead of print.ABSTRACTAmino acids (AAs) are modular building blocks which nature uses to synthesize both macromolecules, such as proteins, and small molecule natural products, such as alkaloids and non-ribosomal peptides. While the 20 main proteinogenic AAs display relatively limited side chain diversity, a wide range of non-canonical amino acids (ncAAs) exist that are not used by the ribosome for protein synthesis, but contain a broad array of structural features and functional groups. In this communication, we report the discovery of the...

Vertical ‐Channel Cathode Host Enables Rapid Deposition Kinetics toward High‐Areal‐Capacity Sodium‐Chlorine Batteries
A free-standing carbon cathode host with lamellar-channel graphene assembly (LGA) is prepared by a bidirectional freezing approach. This is the first time from the perspective of electrode level in Na-Cl2 batteries, to facilitate the SOCl2 transport and regulate the NaCl deposition. Moreover, it can realize stable cycling of Na-Cl2 batteries under high areal capacity. AbstractRechargeable sodium chloride (Na-Cl2) batteries have emerged as promising alternatives for next-generation energy storage due to their superior energy density and sodium abundance. However, their practical applications are hindered by the sluggish chl...
