Soil fungi are essential to ecosystem processes, yet their elevational distribution patterns and the ecological mechanisms shaping their communities remain poorly understood and actively debated, particularly in arid regions. Here, we investigated the diversity patterns and underlying mechanisms shaping soil fungal communities along an elevational gradient (1,707-3,548 m) on the northern slope of the Central Kunlun Mountains in northwest China. Results indicated that the dominant phyla identified across the seven elevational gradients were and , displaying a unimodal pattern and a U-shaped pattern in relative abundance, respectively.

Bio-derived polyethylene glycol (PEG)-based RMs thicken formulations through nonionic-associative thickening where at least two hydrophobic end groups from a RM molecule interact with other hydrophobic groups of other RM molecules or ingredients in the formulation to form an associative network. We report a comprehensive two-dimensional liquid chromatography (2D-LC) separation of partly bio-derived PEG-based RMs in size exclusion chromatography (SEC) × reversed-phase liquid chromatography (RPLC) mode for the separation of RM components based on both molecular weight distribution and end group hydrophobe distribution.

High power pulse generators are moving in the direction of compact, solid-state, and stable working in a relatively long time. In this paper, a compact pulse forming line-Marx type high power pulse generator, based on a ceramic pulse forming line and a spark gap switch with carbide modified graphite electrodes, is studied numerically and experimentally. Specifically, a ceramic based pulse forming line with high relative permittivity was used to achieve long pulse duration in a limited dimension.

Background: Spinal cord injury (SCI) treatment remains a formidable challenge, as current therapeutic approaches provide only marginal relief and fail to reverse the underlying tissue damage. This study aims to develop a novel composite material combining enzymatic nanoparticles and nerve growth factor (NGF) to modulate the immune microenvironment and enhance SCI repair.
Methods: CeMn nanoparticles (NP) and CeMn NP-polyethylene glycol (PEG) nanozymes were synthesized via sol-gel reaction and DSPE-mPEG modification.
Context: The influence of fullerene C60 on the mechanical and thermal properties of natural rubber was systematically investigated using coarse-grained molecular dynamics simulations. The tensile results demonstrate that systems with longer NR chains exhibit reduced tensile strength. Moreover, the addition of C60 nanoparticles significantly enhanced the mechanical properties, with Young's modulus, yield strength, and tensile strength increasing by approximately 24.

However, the actual contribution of TFs, that is TF activity, is not only determined by TF expression, but also accessibility of corresponding chromatin regions. Therefore, we introduce BIOTIC, an advanced Bayesian model with a well-established gene regulation structure that harnesses the power of single-cell multi-omics data to model the gene expression process under the control of regulatory elements, thereby defining the regulatory activity of TFs with variational inference.

The ubiquitous trans-translation system as well as several alternative rescue factors (Arfs) are responsible for rescuing the stalled ribosomes caused by truncated mRNAs that lack the stop codons. To date, protein release factor homolog (PrfH) is the only factor known to rescue the stalled ribosome damaged by ribotoxins.

Neutrophils, traditionally considered as non-specific components of the innate immune system, have garnered considerable research interest due to their dual roles in both promoting and inhibiting tumor progression. This paper seeks to clarify the specific mechanisms by which neutrophils play a bidirectional role in tumor immunity and the factors that influence these roles. By conducting a comprehensive analysis and synthesis of a vast array of relevant literature, it has become evident that neutrophils can influence tumor development and invasive migration through various mechanisms, thereby exerting their anti-tumor effects.

Currently, no standard adjuvant strategies are available for preventing HCC relapse in clinical practice. Impaired natural killer (NK) cell anti-tumor immunity has been disclosed as a crucial root of HCC relapse, indicating that reinstating NK cell anti-tumor immunity may show promise to curb HCC relapse.
