Quaternized cross-linked peach gum polysaccharide as an adsorbent for fast and selective removal of anionic dyes from aqueous solution.

To overcome low adsorption capacity, slow adsorption rate, poor adsorption selectivity, and dissolution of peach gum polysaccharide (PGP), an amino-rich crosslinked PGP (ACPGP) was first synthesized by cross-linking highly soluble PGP. Subsequently, a cation-rich PGP (QCPGP) was prepared from ACPGP through the addition of glycidyltrimethyl ammonium chloride (GTAC) and a secondary quaternization. The step-by-step preparation process was confirmed, and the adsorption properties of PGP, ACPGP, and QCPGP were compared in detail.

Causality between Autism Spectrum Disorder and Telomere Length.

Background: The association between telomere length (TL) and autism spectrum disorder (ASD) has received much attention. However, previous observational studies have yielded inconclusive evidence regarding this relationship. Our study aims to elucidate the causal relationship between TL and ASD using bidirectional Mendelian randomization (MR).

Stimulation of TRPV1+ peripheral somatosensory nerves suppress inflammation via the somato-autonomic reflex.

Excessive inflammation causes a wide range of diseases. Here, we found that stimulating TRPV1+ nerves at the nape activated the nucleus of the solitary tract and C1 neurons in the brainstem via the somatosensory afferent pathway, and rapidly induced the secretion of corticosterone, and drove the vagal-adrenal axis to release serum catecholamines, and activated the autonomic-splenic reflex to suppress cytokine production. RNA sequencing (RNA-seq) analysis revealed that stimulating TRPV1+ nerves significantly changed the expression of genes enriched in multiple pathways related to the inflammatory response in the spleen under pathological and normal physiological conditions.

Understanding its pathogenesis and revealing predictive biomarkers are essential for guiding treatment decisions. In order to explore the global changes of serum metabolites in PE patients and identify potential predictive biomarkers for suspected PE patients (pregnant women who had already shown PE-related symptoms in the middle to late stages of pregnancy, but were not yet confirmatively diagnosed as PE.

3D bioprinted dynamic bioactive living construct enhances mechanotransduction-assisted rapid neural network self-organization for spinal cord injury repair.

Biomimetic neural substitutes, constructed through the bottom-up assembly of cell-matrix modulus via 3D bioprinting, hold great promise for neural regeneration. However, achieving precise control over the fate of neural stem cells (NSCs) to ensure biological functionality remains challenging. Cell behaviors are closely linked to cellular dynamics and cell-matrix mechanotransduction within a 3D microenvironment.

Correlation between dental fluorosis risk and bone-specific alkaline phosphatase, osteocalcin, matrix metalloproteinase and parathyroid hormone in children.

Background: The aim of this study was to investigate the association between dental fluorosis occurrence in children and bone metabolism-related indicators, including bone-specific alkaline phosphatase (BALP), osteocalcin (OC), matrix metalloproteinase (MMP-2, MMP-9, MMP-20), and parathyroid hormone (PTH).

Methods: A total of 189 cases of school-age children who underwent health examinations in our hospital were enrolled, according to the presence or absence of dental fluorosis. They were divided into the fluorosis group (n=97) and fluoride-free group (n=92), and the serum BALP, OC, MMP-2, MMP-9, MMP-20, and PTH levels of the two groups were compared and relevant clinical data were collected.

MT1JP: A Pivotal Tumor-Suppressing LncRNA and its Role in Cancer Progression and Therapeutic Potential.

Metallothionein 1J pseudogene (MT1JP) is a long non-coding RNA (lncRNA) that functions as a tumor suppressor in various malignancies. Reduced MT1JP expression is associated with increased tumor proliferation, migration, invasion, epithelial-mesenchymal transition (EMT), and treatment resistance in nine cancers, such as gastric cancer, intrahepatic cholangiocarcinoma, hepatocellular carcinoma, and breast cancer. Mechanistically, MT1JP acts as a competitive endogenous RNA (ceRNA) to regulate oncogenic microRNAs (miRNAs), including miR-92a-3p, miR-214-3p, and miR-24-3p.

Determination of time lag by accurate monitoring of pressure decay in a new generation constant volume system.

The time-lag method is the standard approach for evaluating membrane permeability, diffusivity and solubility in a single gas permeation experiment. The conventional time-lag method relies on accurately monitoring the pressure rise in a constant volume downstream from the membrane following a change in pressure upstream from the membrane. The same information could be extracted from the upstream pressure decay in the same time-lag experiment.

Methods: A hospital-based oral hygiene training program was developed at Sir Run Run Shaw Hospital's (SRRSH) Dental Clinic with the support of two registered DHs from Loma Linda University in California. A questionnaire evaluating oral health knowledge, attitudes and behaviours was conducted in patients who visited SRRSH's Dental Clinic.

Can minor trauma cause asymptomatic cervical spinal cord compression leading to severe cervical spinal cord injury in rats?

The study aimed to determine whether asymptomatic rats with cervical spinal cord compression (CSCC) experience more severe cervical spinal cord injury (SCI) compared with rats without CSCC under the same degree of minor trauma. Four weeks after the polyvinyl alcohol-polyacrylamide hydrogel was implanted into the C5 vertebral canal, asymptomatic rats were selected based on locomotor function score. Mild cervical SCI was subsequently established based on CSCC.

A Multi-Enzyme Nanocascade to Target Disease-Relevant Metabolites.

Metabolic processes in living organisms depend on the synergistic actions of enzymes working in proximity and in concert, catalyzing reactions effectively while regulating the formation of metabolites. This enzyme synergy offers promising therapeutic application for diseases such as alcohol intoxication, cancer, and hyperinflammation. Despite their potential, the clinical translation of enzyme cascades is restricted by challenges including poor enzyme stability, short half-life, and a lack of delivery strategies that maintain enzyme proximity.

Screening of functional maternal-specific chromatin regulators in early embryonic development of zebrafish.

The early stages of embryonic development rely on maternal products for proper regulation. However, screening for functional maternal-specific factors is challenging due to the time- and labor-intensive nature of traditional approaches. Here, we combine a computational pipeline and F0 null mutant technology to screen for functional maternal-specific chromatin regulators in zebrafish embryogenesis and identify Mcm3l, Mcm6l, and Npm2a as playing essential roles in DNA replication and cell division.

A deep-learning system for diagnosing ectopic eruption.

Objectives: To construct a diagnostic model for mixed dentition using a multistage deep-learning network to predict potential ectopic eruption in permanent teeth by integrating dentition segmentation into the process of automatic classification of dental development stages.

Methods: A database was established by reviewing 1576 anonymous panoramic radiographs of children aged 6-12 years, collected at the Stomatology Hospital, Zhejiang University School of Medicine. These radiographs were categorised as normal or ectopic eruption, with expert diagnoses serving as a benchmark for training and evaluating artificial intelligence (AI) models.

Icariin-loaded chitosan/β-glycerophosphate thermosensitive hydrogel enhanced infection control and bone regeneration in canine with infectious bone defects.

Faced with infectious bone defects, the development of a thermosensitive hydrogel containing icariin (ICA) represents a promising therapeutic strategy targeting infection control and bone regeneration. In this study, we prepared and evaluated the physicochemical properties, in vitro and in vivo drug release, antimicrobial activity, anti-inflammatory properties, and bone repair effects of ICA/Chitosan/β-Glycerophosphate (ICA/CTS/β-GP) thermosensitive hydrogel. Our findings demonstrate that the ICA/CTS/β-GP thermosensitive hydrogel undergoes a liquid-to-gel transition at body temperature, which is crucial for maintaining local drug release at the defect site.

A comparative study of the developability of full-length antibodies, fragments, and bispecific formats reveals higher stability risks for engineered constructs.

Engineered antibody formats, such as antibody fragments and bispecifics, have the potential to offer improved therapeutic efficacy compared to traditional full-length monoclonal antibodies (mAbs). However, the translation of these non-natural molecules into successful therapeutics can be hampered by developability challenges. Here, we systematically analyzed 64 different antibody constructs targeting Tumor Necrosis Factor (TNF) which cover 8 distinct molecular format families, encompassing full-length antibodies, various types of single chain variable fragments, and bispecifics.

Metabolic landscape in venous thrombosis: insights into molecular biology and therapeutic implications.

The findings of the last decade suggest a complex link between inflammatory cells, coagulation, and the activation of platelets and their synergistic interaction to promote venous thrombosis. Inflammation is present throughout the process of venous thrombosis, and various metabolic pathways of erythrocytes, endothelial cells, and immune cells involved in venous thrombosis, including glucose metabolism, lipid metabolism, homocysteine metabolism, and oxidative stress, are associated with inflammation. While the metabolic microenvironment has been identified as a marker of malignancy, recent studies have revealed that for cancer thrombosis, alterations in the metabolic microenvironment appear to also be a potential risk.
