Lignin-intercalated WS with synergistic adsorption for efficiency lead removal.

Tungsten disulfide (WS), a two-dimensional adsorbent material, has garnered great attention in removing lead ions (Pb) from water due to their extensive exposed adsorption sites. However, WS nanosheets inevitably agglomerated and stacked during the preparation and adsorption process, leading to reduced adsorption efficiency. Current method of enhancing WS dispersion is mainly blending with synthetic polymers, but these synthetic polymers themselves do not possess adsorption properties, resulting adsorption effect enhancement poorly.

An audio tampering detection framework for low SNR conditions based on modified CZT.

Extracting the electric network frequency (ENF) from digital audio signals is a crucial means of forensic evidence. However, ENF signal extraction is susceptible to noise, making it challenging to establish a reliable matching relationship with the reference frequency database, especially under low signal-to-noise ratio (SNR) conditions. To solve this problem, an ENF extraction and tampering detection framework (ENF-ETD) for low SNR conditions is proposed in this article.

In-situ lignin assembly on aramid nanofibers: fibrous hybrids for stable and efficient Pb removal.

Constructing lignin-based nano-adsorbents with modulated surface polarity demonstrates promising efficiency, sustainability and biocompatibility in the application of Pb removal, nevertheless, which is hard to achieve. Here, a delicately designed assembly process of amphiphilic lignin was performed on the surfaces of aramid nanofibers (ANF), and a fibrous nano-hybrid (ANF@L) with uniform sheet-like lignin aggregations on ANF was obtained. Ascribing to the dominated π-π stacking between benzene rings on ANF and lignin, the H-bond between them weakened relatively, and more oxygen containing polar groups on lignin were exposed.

Agomirs upregulating carboxypeptidase E expression rescue hippocampal neurogenesis and memory deficits in Alzheimer's disease.

Background: Adult neurogenesis occurs in the subventricular zone (SVZ) and the subgranular zone of the dentate gyrus in the hippocampus. The neuronal stem cells in these two neurogenic niches respond differently to various physiological and pathological stimuli. Recently, we have found that the decrement of carboxypeptidase E (CPE) with aging impairs the maturation of brain-derived neurotrophic factor (BDNF) and neurogenesis in the SVZ.

Polymerizable deep eutectic solvent treated lignocellulose: Green strategy for synergetic production of tough strain sensing elastomers and nanocellulose.

Liquid free ion-conductive elastomers (ICEs) have demonstrated promising potential in various advanced application scenarios including sensor, artificial skin, and human-machine interface. However, ICEs that synchronously possess toughness, adhesiveness, stability, and anti-bacterial capability are still difficult to achieve yet highly demanded.

Sustainable Biochar Nanosheets Derived from Sweet Sorghum Residues via Superbase Pretreatment.

Two-dimensional (2D) sheet-like biochar as promising alternatives to graphene nanosheets has gained significant attention in materials science while being highly restricted by its complicated synthetic steps. In this study, the dimethyl sulfoxide/potassium hydroxide (DMSO/KOH) superbase system was first used to pretreat sweet sorghum residues (SS) and then carbonized to prepare sheet-like biochar. Ascribing to the strong nucleophilicity of DMSO/KOH, a synergistic effect was achieved by partially removing non-cellulosic components in SS and swelling the amorphous region of cellulose, leaving more layered cellulose behind (∼46.

ER Ca overload activates the IRE1α signaling and promotes cell survival.

Background: Maintaining homeostasis of Ca stores in the endoplasmic reticulum (ER) is crucial for proper Ca signaling and key cellular functions. Although Ca depletion has been known to cause ER stress which in turn activates the unfolded protein response (UPR), how UPR sensors/transducers respond to excess Ca when ER stores are overloaded remain largely unclear.

Results: Here, we report for the first time that overloading of ER Ca can directly sensitize the IRE1α-XBP1 axis.

Restoring carboxypeptidase E rescues BDNF maturation and neurogenesis in aged brains.

Adult neurogenesis declines with age due to the less functional neural stem cells (NSCs) and niches, but the underlying molecular bases for this impaired condition remain unclear. Here we analyzed >55,000 single-cell transcriptomes from two discrete neurogenic niches across the mouse lifespan, and identified new features and populations in NSCs, new markers, and neurogenic regional-specific alternations during aging. Intercellular communication analysis revealed defects in brain-derived neurotrophic factor (BDNF)-TrkB signaling cascade in old NSCs.

CAR-T therapy followed by allogeneic hematopoietic stem cell transplantation for refractory/relapsed acute B lymphocytic leukemia: Long-term follow-up results.

Background: Patients with refractory/relapsed (r/r) acute B lymphocytic leukemia (B-ALL) can achieve complete response (CR) after chimeric antigen receptor T-cell (CAR-T) therapy, but recurrence occurs in the short term. To reduce recurrence and improve survival, CAR-T therapy followed by transplantation is a feasible option. We analyzed the long-term follow-up outcomes and the risk factors for allogeneic hematopoietic stem cell transplantation (allo-HSCT) after CR by CAR-T therapy in this study.

The median time from CAR-T infusion to allo-HSCT was 33.

Ca homeostasis maintained by TMCO1 underlies corpus callosum development via ERK signaling.

Transmembrane of coiled-coil domains 1 (TMCO1) plays an important role in maintaining homeostasis of calcium (Ca) stores in the endoplasmic reticulum (ER). TMCO1-defect syndrome shares multiple features with human cerebro-facio-thoracic (CFT) dysplasia, including abnormal corpus callosum (CC). Here, we report that TMCO1 is required for the normal development of CC through sustaining Ca homeostasis.
