Formation of Homogeneous Lignin Nanoparticles from Industrial Kraft Lignin via Fractionation Combined with Antisolvent Precipitation.

Processing lignin into nanoparticles (LNPs) offers a promising utilization strategy; however, its structural and molecular weight heterogeneity poses challenges in the formation of uniform LNPs. In this study, industrial kraft lignin was fractionated in stepwise molecular weight (Mw) from low to high and from which LNPs were fabricated via antisolvent precipitation. The results showed that lignin with high Mw benefits the formation of uniform and smaller-sized LNPs.

Rpl12 is a conserved ribophagy receptor.

Ribophagy is a selective autophagic process that regulates ribosome turnover. Although NUFIP1 has been identified as a mammalian receptor for ribophagy, its homologues do not exist in yeast and nematodes. Here we demonstrate that Rpl12, a ribosomal large subunit protein, functions as a conserved ribophagy receptor in multiple organisms.

Three-dimensional hierarchical urchin-like TiNbO microspheres encapsulated in N-doped carbon for high-rate lithium storage.

Wadsley-Roth phase TiNbO has been known as a potential anode material in high-power lithium-ion batteries (LIBs) owing to its enhanced safety, reliable cycling performance, and substantial theoretical capacity. However, its commercial application is restricted by poor electronic conductivity and slow Li-ion migration kinetics. Herein, we have developed urchin-structured TiNbO microspheres with an ultrathin N-doped carbon coating through a two-step hydrothermal and polydopamine carbonization process.

Zeolite firmly anchored regenerated cellulose aerogel for efficient and biosafe hemostasis.

Zeolite-based hemostats are commercially available but are still troubled by the adverse effects of exothermic heat-caused tissue damage and detached zeolite-induced distal thrombosis. Here, we developed a facile and robust method to fabricate zeolite-embedded regenerated cellulose aerogel (Z-RCA) for safe and efficient hemostasis. Zeolite particles were extensively entangled by regenerated cellulose nanofibers via hydrogen bonds during the cellulose regeneration process, thus reducing the probability of zeolite detaching from aerogel.

Perfluorohexane nanodroplet-assisted mechanical high intensity focused ultrasound cavitation: A strategy for hepatocellular carcinoma treatment.

The activation of immune-stimulatory molecules is critical for effective antitumor immunotherapy. Mechanical high-intensity focused ultrasound (mHIFU) sustains this activation in tumor cell debris through cavitation. To enhance cavitation, perfluorohexane nanodroplets (NDs-PFH) were utilized in this study to lower the cavitation threshold during mHIFU ablation.

Colored Cellulose Nanoparticles with High Stability and Easily Modified Surface for Accurate and Sensitive Multiplex Lateral Flow Assay.

Decentralized testing using multiplex lateral flow assays (mLFAs) to simultaneously detect multiple analytes can significantly enhance detection efficiency, reduce cost and time, and improve analytic accuracy. However, the challenges, including the monochromatic color of probe particles, interference between different test lines, and reduced specificity and sensitivity, severely hinder mLFAs from wide use. In this study, we prepared polydopamine (PDA)-coated dyed cellulose nanoparticles (dCNPs@P) with tunable colors as the probe for mLFAs.

Clinical Relevance of 'Cap' and 'Track' Development after Recent Small Subcortical Infarct.

Objective: After a recent small subcortical infarct (RSSI), some patients develop perilesional or remote hyperintensities ('caps/tracks') to the index infarct on T2/FLAIR MRI. However, their clinical relevance remains unclear. We investigated the clinicoradiological correlates of 'caps/tracks', and their impact on long-term outcomes following RSSI.

Apoptotic breast cancer cells after chemotherapy induce pro-tumour extracellular vesicles via LAP-competent macrophages.

Chemotherapy is important in the systemic therapy for breast cancer. However, after chemotherapy, the left living tumour cells are more progressive. There is an urgent need to study the underlying mechanism which is still unclear to further improve the therapeutic efficacy of chemotherapy in breast cancer.

Regenerated carboxymethyl cellulose beads for selective removal of low-density lipoprotein from whole blood.

Low-density lipoprotein (LDL) plays a crucial role in the development of cardiovascular disease. Lowering the level of LDL is an effective therapeutic strategy for treating cardiovascular disease. Here, we developed a facile and robust method to prepare carboxymethyl cellulose beads (CMCBs) for selectively adsorbing LDL.

Cold storage promotes germination and colonization of arbuscular mycorrhizal fungal hyphae as propagules.

The inoculants of arbuscular mycorrhizal fungi (AMF) propagated by the culture system is important in scientific research; however, the long-term storage reduces the spore germination rate. The propagules of AMF consist of three components, including spores, hyphae and colonized root fragments. It is well known that cold storage can improve the germination rate of AMF spores, with limited investigations on the germination of other propagules.

Retinal microvascular phenotypes can track small vessel disease burden and CPAP treatment effectiveness in obstructive sleep apnoea.

Optical coherence tomography angiography (OCT-A) retinal imaging enables visualization of the retinal microvasculature that is developmentally related to the brain and can offer insight on cerebrovascular health. We investigated retinal phenotypes and neuroimaging markers of small vessel disease (SVD) in individuals with obstructive sleep apnoea (OSA). We enrolled 44 participants (mean age 50.

Drought stress reduces arbuscular mycorrhizal colonization of (L.) roots and plant growth promotion via lipid metabolism.

Drought stress poses increasingly serious threats to agricultural production in the era of global climate change. Arbuscular mycorrhizal (AM) fungi are well-recognized biostimulants promoting plant tolerance to drought stress. Lipids are indispensable for AM fungal colonization, however, the involvement of lipid metabolism in the drought tolerance conferred by AM fungi is largely unknown.

Identifying who are unlikely to benefit from total knee arthroplasty using machine learning models.

Identifying and preventing patients who are not likely to benefit long-term from total knee arthroplasty (TKA) would decrease healthcare expenditure significantly. We trained machine learning (ML) models (image-only, clinical-data only, and multimodal) among 5720 knee OA patients to predict postoperative dissatisfaction at 2 years. Dissatisfaction was defined as not achieving a minimal clinically important difference in postoperative Knee Society knee and function scores (KSS), Short Form-36 Health Survey [SF-36, divided into a physical component score (PCS) and mental component score (MCS)], and Oxford Knee Score (OKS).

Concisely Constructing S, F Co-Modified MnO Nanoparticles Attached to S, N Co-Doped Carbon Skeleton as a High-Rate Performance Anode Material.

The utilization of MnO anodes with high storage capacity is significantly hindered by rapid capacity fading and inadequate rate capability, stemming from substantial volume fluctuations and low electrical conductivity. Crafting a composite comprising sulfur and fluorine co-modified MnO nanoparticles integrated with sulfur and nitrogen co-doped carbon matrices promises enhanced electrochemical performance yet poses formidable obstacles. Here, we present a straightforward synthetic strategy for in situ growth of sulfur and fluorine co-modified MnO nanoparticles onto sulfur and nitrogen co-doped carbon scaffolds.

Impact of sleep disturbance on longitudinal cognitive performance in patients with transient ischemic attack or mild stroke.

Introduction: Sleep disturbances including obstructive sleep apnea (OSA) and poor sleep quality are common after stroke, while its association with cognitive changes following transient ischemic attack (TIA) or mild stroke remains unclear. We aim to determine whether sleep duration, OSA parameters, or nocturnal hypoxemia is associated with a greater cognitive decline after stroke.

Methods: We prospectively followed-up patients with acute TIA/mild stroke [National Institute Health Stroke Scale (NIHSS) < 7] who underwent baseline sleep questionnaire [Pittsburgh Sleep Quality Index (PSQI)], and serial cognitive assessments [Montreal Cognitive Assessment (MoCA) 5-min, Stroop Test] at baseline and one-year.

The Biosynthesis of Bacterial Cellulose Composites Accompanied by Spray Feeding of Biomasses.
