Purification of harvested rainwater using gravity-driven ceramic membrane: A visualization study combining Micro-CT and COMSOL simulations.

Rainwater harvesting is a viable solution for providing clean water in regions where conventional water sources are scarce or contaminated. However, the harvested rainwater often contains microorganisms, suspended particles, and other impurities that must be removed before consumption. Gravity-driven ceramic membranes (GDCMs) are an efficient choice for purifying harvested rainwater due to their energy-saving properties.

Effect of therapeutic erythrocytapheresis on outcomes and renal benefit in patients with high-altitude polycythemia: a real-world study.

Kidney injury from high-altitude polycythemia (HAPC) is common, yet few studies have explored effective treatments. This research assessed the renal benefits of therapeutic erythrocytapheresis (TE) in HAPC patients, analyzing the efficacy of single versus multiple treatments. From 2017 to 2023, 631 patients undergoing TE were included.

Processing of N-glycans in the ER and Golgi influences the production of surface sialylated glycoRNA.

Glycoconjugates, including glycans on proteins and lipids, have obtained significant attention due to their critical roles in both intracellular and intercellular biological functions and processes. Notably, recent discoveries have revealed the presence of glycosylated RNAs (glycoRNAs) on cell surfaces. Despite the well-characterized roles of RNA modifications, RNA glycosylation remains relatively unexplored.

Migration patterns of phthalic acid esters from mulch plastic film in the soil-plant-atmosphere continuum system.

Plastic film mulching is an important agricultural practice, but its release of phthalic acid esters (PAEs) poses threats to soil and human health. However, the migration patterns of PAEs during the lifecycle of mulch plastic film (MPF) remain unclear. This study aims to explore the temporal patterns of release of PAEs during the MPF's lifecycle and evaluate the migration patterns of PAEs from MPF in the soil-plant-atmosphere continuum (SPAC) system through pot experiments and model simulations.

Chromosome-level genome provides insights into evolution and diving adaptability in the vulnerable common pochard (Aythya ferina).

The common pochard (Aythya ferina) is a freshwater diving duck found in the Palearctic region that has been classified as vulnerable by the IUCN due to continuous and rapid population declines across their distribution. To gain a better understanding of its genetic mechanism of adaptive evolution, we successfully sequenced and assembled the first high-quality chromosome-level genome of A. ferina using Illumina, Nanopore and Hi-C sequencing technologies.

Complete mitochondrial genome and phylogenetic analysis of (Passeriformes: Fringillidae).

In this study, we employed high-throughput metagenomic data to assemble the mitochondrial genome (mitogenome) of the European greenfinch (; Linnaeus 1758). The circular mitogenome was 16,813 base pairs (bp) in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 control region. The base composition of the mitogenome is 30.

Site-directed mutagenesis leads to the optimized transglycosylation activity of endo-beta-N-acetylglucosaminidase from Trypanosoma brucei.

Endo-β-N-acetylglucosaminidases (ENGases) are pivotal enzymes in the degradation and remodeling of glycoproteins, which catalyze the cleavage or formation of β-1,4-glycosidic bond between two N-acetylglucosamine (GlcNAc) residues in N-linked glycan chains. It was investigated that targeted mutations of amino acids in ENGases active site may modulate their hydrolytic and transglycosylation activities. Endo-Tb, the ENGase derived from Trypanosoma brucei, belongs to the glycoside hydrolase family 85 (GH85).

Comparative analysis of the gut microbiome of ungulate species from Qinghai-Xizang plateau.

Several studies have investigated the gut bacterial composition of wild ungulates in the Qinghai-Xizang Plateau. However, the relationship between their gut microbiome dendrograms and their phylogenetic tree remains unclear. In this study, we analyzed 45 amplicons (V3-V4 region of the 16S rRNA gene) from five wild ungulates-, , , , and -from the Qinghai-Xizang Plateau to clarify the relationship between their phylogenies and gut microbiome dendrograms.

The total length of the mitogenome was found to be 16,872 base pairs (bp), containing 13 protein-coding genes (PCGs), 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region. The nucleotide composition was as follows: A 30.

Lysosomes drive the piecemeal removal of mitochondrial inner membrane.

Mitochondrial membranes define distinct structural and functional compartments. Cristae of the inner mitochondrial membrane (IMM) function as independent bioenergetic units that undergo rapid and transient remodelling, but the significance of this compartmentalized organization is unknown. Using super-resolution microscopy, here we show that cytosolic IMM vesicles, devoid of outer mitochondrial membrane or mitochondrial matrix, are formed during resting state.

Electrothermal mineralization of per- and polyfluoroalkyl substances for soil remediation.

Per- and polyfluoroalkyl substances (PFAS) are persistent and bioaccumulative pollutants that can easily accumulate in soil, posing a threat to environment and human health. Current PFAS degradation processes often suffer from low efficiency, high energy and water consumption, or lack of generality. Here, we develop a rapid electrothermal mineralization (REM) process to remediate PFAS-contaminated soil.

Enhancing higher-order modal response in multifrequency atomic force microscopy with a coupled cantilever system.

Multifrequency atomic force microscopy (AFM) utilizes the multimode operation of cantilevers to achieve rapid high-resolution imaging and extract multiple properties. However, the higher-order modal response of traditional rectangular cantilever is weaker in air, which affects the sensitivity of multifrequency AFM detection. To address this issue, we previously proposed a bridge/cantilever coupled system model to enhance the higher-order modal response of the cantilever.

[Analysis of enzyme activity and substrate specificity of dolichyl-phosphate β-glucosyltransferase].

Protein folding and quality control processes primarily occur in the endoplasmic reticulum (ER). ER-resident molecular chaperones play a crucial role in guiding nascent polypeptides towards their correct tertiary structures. Some of these chaperones specifically recognize glucosylated -glycan moieties on peptide.

Accurate etiological diagnosis of mediastinitis in immunocompetent patients using metagenomic next-generation sequencing: a case series and literature review.

Background: As a culture-independent method, metagenomic next-generation sequencing (mNGS) is widely used in microbiological diagnosis with advantages in identifying potential pathogens, guiding antibiotic therapy, and improving clinical prognosis, especially in culture-negative cases. () mediastinitis is a rare and severe disease for which etiological diagnosis is important but challenging. The application of mNGS in the etiological diagnosis of mediastinitis has seldom been studied.

In this study, the performance of probe capture-based targeted next-generation sequencing (tNGS) was compared to that of blood culture and metagenomic next-generation sequencing (mNGS) in detecting potential pathogens in patients with BSI.

Methods: A total of 80 patients with suspected BSI were prospectively enrolled from 24 November 2023 to 30 December 2023 at Zhongshan Hospital, Shanghai, China.

Adaptive under-sampling strategy for fast imaging in compressive sensing-based atomic force microscopy.

Compressive sensing (CS) can reconstruct the rest information almost without distortion by advanced computational algorithm, which significantly simplifies the process of atomic force microscope (AFM) scanning with high imaging quality. In common CS-AFM, the partial measurements randomly come from the whole region to be measured, which easily leads to detail loss and poor image quality in regions of interest (ROIs). Consequently, important microscopic phenomena are missed probably.

Enhancing soil health and nutrient cycling through soil amendments: Improving the synergy of bacteria and fungi.

The synergy between bacteria and fungi is a key determinant of soil health and have a positive effect on plant development under drought conditions, with the potentially enhancing the sustainability of amending soil with natural materials. However, identifying how soil amendments influence plant growth is often difficult due to the complexity of microorganisms and their links with different soil amendment types and environmental factors. To address this, we conducted a field experiment to examine the impact of soil amendments (biochar, Bacillus mucilaginosus, Bacillus subtilis and super absorbent polymer) on plant growth.
