Gαi1/3 signaling mediates IL-5-induced eosinophil activation and type 2 inflammation in eosinophilic chronic rhinosinusitis.

Background: Uncontrolled severe eosinophilic chronic rhinosinusitis (eCRS) is associated with elevated levels of Th2 cells and raised immunoglobulin concentrations in nasal polyp tissue. eCRS is characterized by high eosinophilic infiltration and type 2 inflammation. Gαi1/3 proteins participate in allergic inflammation by regulating immune cells.

Preliminary evaluation of the FastCAP for users of the Nurotron cochlear implant.

Background: Electrically evoked compound action potential (ECAP) can be used to measure the auditory nerve's response to electrical stimulation in cochlear implant (CI) users. In the Nurotron CI system, extracting the ECAP waveform from the stimulus artifact is time-consuming.

Method: We developed a new paradigm ("FastCAP") for use with Nurotron CI devices.

Background: Lung adenocarcinoma (LUAD) is the most common histological subtype of lung cancer. JAM2, a member of the Junctional adhesion molecule (JAM) family, plays diverse roles in cell-cell contacts and tumor development. Although JAM2's expression and functions have been reported in various cancers, its clinical and biological significance in LUAD remains unclear.

Time-dependent diffusion magnetic resonance imaging for the analysis of parotid gland tumors.

Background: Different parotid tumors differ in terms of treatment strategies due to their distinct biological behaviors. Time-dependent diffusion magnetic resonance imaging (t-dMRI) can characterize and quantify the cytological indexes, and then aid the differential diagnosis of various tumors. However, the value of t-dMRI in the analysis of parotid gland tumors remains unclear.

Fractionated radiotherapy initiated at the early stage of bone metastasis is effective to prolong survival in mouse model.

Background And Purpose: Bone metastasis is common for breast cancer and associated with poor prognosis. Currently, radiotherapy (RT) serves as the standard treatment for patients exhibiting symptoms of bone metastasis to alleviate pain. Whether earlier application of RT will better control bone metastasis remains unclear.

Positively charged cytoplasmic residues in corin prevent signal peptidase cleavage and endoplasmic reticulum retention.

Positively charged residues are commonly located near the cytoplasm-membrane interface, which is known as the positive-inside rule in membrane topology. The mechanism underlying the function of these charged residues remains poorly understood. Herein, we studied the function of cytoplasmic residues in corin, a type II transmembrane serine protease in cardiovascular biology.

Patient Concerns: The patient still experienced MCAO after conventional bronchoscopic interventional therapy.

Diagnoses: The patient was diagnosed as lung adenocarcinoma stage IV (T4N2M1a).

The clinical significance of mirror patterns of cerebrospinal fluid oligoclonal immunoglobulin G bands (IgG-OCBs) in peripheral neuropathy disorders.

Background: CSF (cerebrospinal fluid) oligoclonal immunoglobulin G bands (IgG-OCBs) analysis plays a crucial role in diagnosis of various neurological disorders. However, the clinical significance of mirror pattern bands remains unclear, and their precise application is not well understood.

Methods: We retrospectively reviewed a total of 7597 IgG-OCB records detected using isoelectric focusing from May 2020 and August 2023 at Huashan Hospital.

Disruption of the Pum2 axis Aggravates neuronal damage following cerebral Ischemia-Reperfusion in mice.

Stroke remains a leading cause of disability and mortality worldwide, with mitochondrial dysfunction closely linked to ischemic injury. This study explores the Norad-Pum2-Mff axis as a key regulator of mitochondrial function following ischemia-reperfusion (I/R) injury. Using an oxygen-glucose deprivation/reoxygenation (OGD/R) model, Mff protein levels were significantly elevated post-OGD/R, while mRNA levels remained unchanged, suggesting post-transcriptional regulation.

Bioactive Silk Cryogel Dressing with Multiple Physical Cues to Control Cell Migration and Wound Regeneration.

Introducing multiple physical cues to control cell behaviors effectively is considered as a promising strategy in developing bioactive wound dressings. Silk nanofiber-based cryogels are developed to favor angiogenesis and tissue regeneration through tuning hydrated state, microporous structure, and mechanical property, but remained a challenge to endow with more physical cues. Here, β-sheet rich silk nanofibers are used to develop cryogels with nanopore structure.

Clinical and Carotid Plaque Features in Symptomatic and Asymptomatic Ischemic Stroke.

Ischemic stroke (IS), a cerebrovascular condition, is commonly detected by evaluating carotid intima-media (CIA) stenosis. Symptomatic CIA stenosis carries a high risk (up to 32%) of another ischemic event within 12 weeks, while asymptomatic CIA stenosis has an annual risk ranging from 1% to 2%. Therefore, this study aims to explore the diagnostic value of clinical features and carotid plaque characteristics in both symptomatic and asymptomatic IS.

Identification of serum biomarkers and therapeutic targets for aortic diseases in obesity through multi-omics analysis.

Background: Obesity is associated with an increased risk of aortic diseases and operative risks. Currently, there are no effective drugs available to prevent the occurrence and progression of aortic aneurysms or dissections. We investigated potential biomarkers and therapeutic targets using a multi-omics approach.

The effectiveness and safety of computed tomography-guided hook-wire localization for secondary video-assisted thoracoscopic surgery: a retrospective study.

Background: Computed tomography (CT)-guided hook-wire localization is currently the most commonly used technique for preoperative localization of pulmonary nodules in clinical practice. With the increasing incidence of multiple primary lung cancers and the increasing occurrence of second primary lung cancers or local recurrences after lung cancer surgery, some patients need to undergo an ipsilateral or contralateral second pulmonary resection. In order to reduce the surgical difficulty of the second operation and accurately guide the surgical resection, preoperative localization of some nodules is necessary.

Autophagy serves as a protective effect against inflammatory injury of oxidative stress in ARPE-19 cell.

Aim: To test the effect of autophagy on inflammatory damage resulting from oxidative stress in adult retinal pigment epithelial cell line (ARPE-19).

Methods: ARPE-19 cells were pretreated with 200 and 600 µmol/L hydrogen peroxide (HO) at various time intervals. The changes of cell morphology, cell viability, reactive oxygen species (ROS) level, autophagic activity, and the inflammatory cytokines (TNFα, IL-6, and TGFβ) were measured at baseline and after treatment with autophagy inducer rapamycin (Rapa) and suppressor wortmannin (Wort) or shATG5.

Association between epigenetic aging and atrioventricular block: a two-sample Mendelian randomization study.

Aims: Atrioventricular block (AVB) is a prevalent bradyarrhythmia. This study aims to investigate the causal effects of epigenetic aging, as inferred from DNA methylation profiles on the prevalence of AVB by Mendelian randomization (MR) analysis.

Methods: Genetic instruments for epigenetic aging and AVB were obtained from genome-wide association study data in the Edinburgh DataShare and FinnGen biobanks.

Development and validation of a nomogram for predicting cough variant asthma diagnosis.

Background: Cough variant asthma (CVA) is a specific type of asthma characterized by chronic cough as the sole or predominant symptom. Accurate diagnosis is crucial for effective treatment, yet bronchial provocation test is not always feasible in clinical settings. To identify independent predictors of CVA diagnosis, we developed a nomogram for predicting CVA.
