A new method for the quantification of polysaccharide structural domain: Rapid quantification of Rhamnogalacturonan-II by colorimetry.

Polysaccharides are important pharmacodynamically active components in traditional Chinese medicines and based on the type of monosaccharides and glycosidic linkages, they can be divided into different structural domains. Rhamnogalacturonan II (RG-II) is among the most complex and conserved structural domain within polysaccharides and possesses significant pharmacological effects. Nevertheless, there is no suitable method for quantifying homogeneous polysaccharides that contain the RG-II structural domain.

Macrophage Membrane-Camouflaged Nanozymes for Combating the Oxidative Stress-Microvascular Perfusion Negative Feedback in Ischemia-Reperfusion Induced Acute Kidney Injury.

Oxidative stress plays a critical role in the pathogenesis of ischemia-reperfusion injury (IRI)-induced acute kidney injury (AKI), driving necrosis of proximal tubule cells, inflammation, and capillary rarefaction. Inadequate perfusion resulting from capillary rarefaction can, in turn, induce chronic tissue hypoxia and exacerbate ischemic acute tubular necrosis, leading to an "oxidative stress-microvascular perfusion" negative feedback that further aggravate kidney damage. In this study, a macrophage membrane-camouflaged manganese-based antioxidant nanozyme (MB@LM) is developed for targeted delivery and oxidative stress relief in AKI therapy.

Downregulation of AATK enhances susceptibility to ferroptosis by promoting endosome recycling in gefitinib-resistant lung cancer cells.

Ferroptosis has been characterised by disruption of the cell membrane through iron-related lipid peroxidation. However, regulation of iron homeostasis in lung cancer cells that are resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) remains unclear. Transcriptome analysis identified a significant downregulation of apoptosis-associated tyrosine kinase (AATK) mRNA expression in gefitinib-resistant PC9 (PC9-GR) cells, which were found to be more susceptible to ferroptosis inducers.

MAFLD as a predictor of adverse cardiovascular events among CHD patients with LDL-C<1.8 mmol/L.

Background And Aims: Patients receiving statin therapy still suffer from adverse cardiovascular events. Metabolic (dysfunction)-associated fatty liver disease (MAFLD) is a newly proposed concept that shares common metabolic risk factors with cardiovascular disease. This study aimed to investigate the association between MAFLD and adverse cardiovascular outcomes in coronary heart disease (CHD) patients with LDL-C<1.

CENP-E haploinsufficiency causes chromosome misalignment and spindle assembly checkpoint activation in the spermatogonia.

Background: The establishment of kinetochore-microtubule attachment is essential for error-free chromosome alignment and segregation during cell division. Defects in chromosome alignment result in chromosome instability, birth defects, and infertility. Kinesin-7 CENP-E mediates kinetochore-microtubule capture, chromosome alignment, and spindle assembly checkpoint in somatic cells, however, mechanisms of CENP-E in germ cells remain poorly understood.

Protocol for in situ and in vivo dissection of mouse lung-draining lymph nodes.

Lung-draining lymph nodes (LNs) play crucial roles in infection, inflammation, and cancer, but in situ and in vivo studying models are technically challenging. Here, we present a protocol for the in situ and in vivo dissection of mouse lung-draining LNs, ensuring postoperative survival. We describe steps for lymphadenectomy including localizing lung-draining LNs, open thoracotomy, and LN dissection.

Dynamics in the prevalence and clinical manifestations of acute mountain sickness of different ascent protocols during high altitudes exposure.

Observation of Attosecond Time Delays in Above-Threshold Ionization.

Attosecond-scale temporal characterization of photoionization is essential in understanding how light and matter interact on the most fundamental level. However, characterizing the temporal property of strong-field above-threshold ionization has remained unreached. Here, we propose a novel photoelectron interferometric method to disentangle the contribution of Coulomb effect from an attoclock, allowing us to clock energy-resolved time delays of strong-field above-threshold ionization.

Stretchable, self-adhesive, and conductive hemicellulose-based hydrogels as wearable strain sensors.

Conductive hydrogels have recently gained impressive attention in flexible sensing. However, their low sensing limit and poor interface matching have raised great concern during the practical application. Therefore, incorporating excellent stretchability and adhesiveness into conductive hydrogel is highly desirable but still be a huge challenge.

Higher skin sympathetic nerve activity as a potential predictor of overactive bladder in females refractory to oral monotherapy.

This study investigates predictors of unsatisfactory outcomes in female overactive bladder (OAB) patients treated with oral monotherapy by analyzing skin sympathetic nerve activity (SKNA) using a novel "neuECG" method. The study included 55 newly diagnosed female patients with idiopathic OAB, autonomic function was evaluated using neuECG before treatment initiation, and validated OAB questionnaires and urodynamic studies were administered. Initial monotherapy was administered for the first 4 weeks, with non-responders defined as patients not achieving satisfactory symptom relief and requiring further treatment.

Evaluation of Health Associations With Height-Normalised Abdominal Body Composition Indices: A Single-Centre Cross-Sectional Study.

Background: Traditional metrics such as body mass index (BMI) and waist circumference (WC) fail to accurately assess the health outcomes associated with abdominal adiposity, because they neglect the intricacies of adipose tissue distribution. Notably, the variability in body composition scaled to height remains underexplored in Chinese demographics. This study introduces height-normalised indices of abdominal adiposity using computed tomography (CT) scans and further assesses their associations with various health outcomes.

Kinesin-7 CENP-E mediates centrosome organization and spindle assembly to regulate chromosome alignment and genome stability.

Chromosome congression and alignment are essential for cell cycle progression and genomic stability. Kinesin-7 CENP-E, a plus-end-directed kinesin motor, is required for chromosome biorientation, congression and alignment in cell division. However, it remains unclear how chromosomes are aligned and segregated in the absence of CENP-E in mitosis.

Adenoid cystic carcinoma: insights from molecular characterization and therapeutic advances.

Adenoid cystic carcinoma (ACC) is a malignant tumor primarily originating from the salivary glands, capable of affecting multiple organs. Although ACC typically exhibits slow growth, it is notorious for its propensity for neural invasion, local recurrence, and distant metastasis, making it a particularly challenging cancer to treat. The complexity of ACC's histological and molecular features poses significant challenges to current treatment modalities, which often show limited effectiveness.
