TMEM115: a promising marker for glioma immunotherapy and prognosis.

Background: Glioma is a common malignant primary brain tumor characterized by a highly immunosuppressive tumor microenvironment and unfavorable prognosis. Transmembrane protein 115 (TMEM115) is a protein-coding gene. It may play a role in the retrograde transport of proteins from the Golgi to the endoplasmic reticulum.

Facile synthesis of ultratough conductive gels with swelling and freezing resistance for flexible sensor applications.

The application of flexible hydrogel sensors in extreme environments, such as low temperatures, underwater, or significant mechanical deformations, poses considerable challenges. Here, we present a simple one-pot method to fabricate ultra-tough, swelling- and freezing-resistant conductive organohydrogels without external conductive and freeze-resistant fillers. During gelation, by-products (CHNHCl, KCl) provide both conductivity and antifreeze properties, thus eliminating compatibility issues and dispersion challenges associated with external fillers.

Surprisingly fast self-healing coatings with anti-fog and antimicrobial activities via host-guest interaction.

Dual functional coatings with anti-fog and antimicrobial performances greatly enhance the safety and reliability of medical detection devices, but are prone to mechanical damage, resulting in reduced performance and a shorter service lifespan. Herein, a semi-interpenetrating polymer network (SIPN) coating, featuring hydrophobic-hydrophilic balanced copolymers as bulk chains and host-guest inclusion compounds (HGICs) as cross-linkers, is reported, which demonstrates particularly effective anti-fog and antibacterial performances, along with a surprisingly fast self-healing capability under various scenarios. This HGIC-based coating displayed remarkable anti-fog capability over a wide temperature range from -20 ℃ to 85 ℃ and exhibited reliable antibacterial activities (≥98 %) against both gram-positive and gram-negative bacteria.

The right microbe-associated molecular patterns for effective recognition by plants.

Plants are constantly exposed to diverse microbes and thus develop a sophisticated perceive system to distinguish non-self from self and identify non-self as friends or foes. Plants can detect microbes in apoplast recognition of microbe-associated molecular patterns (MAMPs) by pattern recognition receptors (PRRs) on the cell surface to activate appropriate signaling in response to microbes. MAMPs are highly conserved but essential molecules of microbes and often buried in microbes' complex structure.

Plants Play Stronger Effects on Soil Fungal than Bacterial Communities and Co-Occurrence Network Structures in a Subtropical Tree Diversity Experiment.

Increasing biodiversity loss profoundly affects community structure and ecosystem functioning. However, the differences in community assembly and potential drivers of the co-occurrence network structure of soil fungi and bacteria in association with tree species richness gradients are poorly documented. Here, we examined soil fungal and bacterial communities in a Chinese subtropical tree species richness experiment (from 1 to 16 species) using amplicon sequencing targeting the internal transcribed spacer 2 and V4 hypervariable region of the rRNA genes, respectively.

One-step synthesis of quaternized silica nanoparticles with bacterial adhesion and aggregation properties for effective antibacterial and antibiofilm treatments.

Preservation of the intact cell morphology of bacteria is recognized as one important cause of bacterial drug resistance, and hence developing new antibacterial agents capable of fighting against bacteria disrupting their cell envelope is highly desirable. Herein, by adopting a modified Stöber method, we developed a one-step approach to fabricate quaternized silica nanoparticles (NPs) using two commercially available molecules-a long alkyl chain-bearing quaternary ammonium silane compound, dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (Si-QAC), and tetraethyl orthosilicate (TEOS). Specifically, small spherical quaternized silica NPs with an average size of ∼34 nm could be prepared at a TEOS/Si-QAC molar ratio of 4 : 1 with a very high yield (>90%), and the resultant NPs (termed TS4 NPs) possessed superb colloidal stability (at least 520 d) and good biocompatibility.

An aggregation-induced emission fluorescence probe for evaluating the effect of CYP450 changes under tumor chemotherapy.

Cancer is a complex disease with very high incidence and mortality rates every year. However, cancer drug resistance greatly mitigates the cure rates of tumors, and cytochrome P450 (CYP450) plays an important role in the development of cisplatin resistance. We developed the aggregation-induced emission luminogen (AIEgen) TPE-CYP to monitor the changes in CYP450.

Evaluate the bisphenol A-induced redox state in cells, zebrafish and in vivo with a hydrogen peroxide turn-on fluorescent probe.

Hydrogen peroxide (HO) is an important active oxygen species that plays a major role in redox balance and in physiological and pathological processes of various diseases of biological systems. As HO is an endogenous active molecule, fluctuations in HO content are not only affected by the state of biological system itself but also easily affected by Bisphenol A (BPA, a typical estrogenic environmental pollutant) in the external environment. Here, the near-infrared fluorescent probe Cy-NOH2 (λ = 750 nm) as a tool was synthesized to detect fluctuations in HO content in cells and organisms induced by BPA.

Near-Infrared Fluorescent Probe for Imaging and Evaluating the Role of Vanin-1 in Chemotherapy.

Pantetheinase (also known as Vanin-1) is highly expressed in the liver, kidneys, and intestine and is closely associated with a number of diseases. Vanin-1 can hydrolyze pantetheine to pantothenic acid (vitamin B5) and cysteamine and participate in the synthesis of glutathione (GSH). GSH is highly expressed in tumor cells and plays a major role in the resistance of tumor cells to cisplatin.

Response of arbuscular mycorrhizal fungal community in soil and roots to grazing differs in a wetland on the Qinghai-Tibet plateau.

Grazing as one of the most important disturbances affects the abundance, diversity and community composition of arbuscular mycorrhizal (AM) fungi in ecosystems, but the AM fungi in response to grazing in wetland ecosystems remain poorly documented. Here, we examined AM fungi in roots and soil in grazing and non-grazing plots in Zoige wetland on the Qinghai-Tibet plateau. Grazing significantly increased AM fungal spore density and glomalin-related soil proteins, but had no significant effect on the extra radical hyphal density of AM fungi.
