Enhancement mechanism of ι-carrageenan on the network structure and gel-related properties of soy protein isolate (SPI)/λ-carrageenan system was investigated. Adding ι-carrageenan decreased SPI particles' size in nano-scale, reduced hydrophobic interactions by suppressing exposure of hydrophobic groups, and increased the disulfide bonds in SPI. With rising ι-carrageenan content (< 0.55 %), the interaction between ι-carrageenan and SPI was enhanced mainly through electrostatic interaction and hydrogen bond. Meanwhile, SPI particles were reduced and their stacking compactness was increased as well. These contributed to the improvement of network structure and thus increased weakly bonded water from 97.7 to 98.5 %, water holding capacity from 55.29 % to 61.70 % and gel hardness from 0.53 to 1.30 N. Higher ι-carrageenan content (> 0.55 %) induced micro-phase separation as shown by CLSM images, and led to reduction of gel hardness. These results favor the rational design and application of SPI-based gel systems with desired practical properties.

The treatment of biodegradable plastics through composting has garnered increasing attention. This study aimed to investigate the effects of Biochar FN1 bacteria and ferrous sulfate on nitrogen retention, greenhouse gas emissions, and degradable plastics during composting and to elucidate their synergistic mechanisms on microbial communities. Compared with the control, applying biochar-loaded FN1 bacteria composites combined with Ferrous sulfate (SGC) markedly accelerated organic matter degradation and reduced cumulative CO and NH emissions.

The number and distribution of trichomes, i.e., the trichome pattern, in different plant organs shows a conspicuous inter- and intraspecific diversity across Angiosperms that is presumably involved in adaptation to numerous environmental factors.

Tissue clearing enables deep imaging of long biological structures using light microscopy approaches. Protocols such as iDISCO are not currently available for human skin. Here, we present Skin-iDISCO, a tissue-clearing and labeling protocol for morphometric analysis of human cutaneous vasculature.

Much brain imaging work has underscored the functional connections among the inferior frontal gyrus (IFG; articulation), supramarginal gyrus (SMG; letter-sound correspondence), superior temporal gyrus (STG; sound) and fusiform gyrus (FFG; print) during basic reading processes. This reading network supports and coordinates the complex processes that contribute to successful reading. In line with the Hebbian notion that 'neurons that fire together, wire together' we examined cortical thickness among these regions and the extent to which these regions showed structural relationships in average and impaired readers.

O'Donnell-Luria-Rodan (ODLURO) syndrome is an autosomal dominant neurodevelopmental disorder mainly characterized by global development delay/intellectual disability, white matter abnormalities, and behavioral manifestations. It is caused by pathogenic variants in the KMT2E gene. Here we report seven new patients with loss-of-function KMT2E variants, six harboring frameshift/nonsense changes, and one with a 7q22.
