In our previous phase II T1219 trial for advanced biliary tract cancer (ABTC), the combination of nivolumab with modified gemcitabine and S-1 exhibited promising efficacy, while the programmed-death-ligand-1 (PD-L1) expression did not predict chemoimmunotherapy efficacy. Lymphocyte-activation-gene-3 (LAG-3), a negative immune checkpoint, is frequently co-expressed with PD-L1. This study assessed the predictive value of LAG-3 expression in ABTC patients who received chemoimmunotherapy.

Objective: Our study investigated how arecoline-induced extracellular vesicle (EV) secretion suppresses PAX1 protein production through DNA hypermethylation and examined whether PAX1 downregulation enhances cancer stemness and immunosuppression in the tumor microenvironment.

Materials And Methods: EVs were isolated from SAS/TW2.6 cancer cell lines using ultracentrifugation and identified using transmission electron microscopy.

Immune checkpoint inhibitors (ICI) represent new anticancer agents and have been used worldwide. However, ICI can potentially induce life-threatening severe cutaneous adverse reaction (SCAR), such as Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), hindering continuous ICI therapy. We examine 6 cohorts including 25 ICI-induced SJS/TEN patients and conduct single-cell RNA sequencing (scRNA-seq) analysis, which shows overexpression of macrophage-derived CXCL10 that recruits CXCR3 cytotoxic T lymphocytes (CTL) in blister cells from ICI-SJS/TEN skin lesions.

Objective: Heart rate serves as a critical prognostic factor in heart failure (HF) patients. We hypothesise that elevated heart rate in critically ill HF patients on discharge from the intensive care unit (ICU) could be linked to adverse outcomes.

Design: A single-centre retrospective cohort study.

In the present study, an algae-containing octocoral, Junceella fragilis, was subjected to chemical screening. The analysis resulted in the extraction of six polyacetoxybriaranes: a new compound, identified as fragilide Z (1), alongside previously identified analogs, which included 12-epi-fragilide G (2), fragilide P (3), junceellolide D (4), junceellonoid A (5), and juncin ZI (6). The structures of compounds 2-6 were investigated through single-crystal X-ray diffraction analysis, whereas that of 1 was examined through two-dimensional nuclear magnetic resonance analysis.

Background: Immune checkpoint inhibitors (ICIs) are associated with an increased risk of major adverse cardiovascular events (MACE). Glucagon-like peptide-1 agonists (GLP1a), initially developed for type 2 diabetes mellitus (T2DM), have shown promising results in reducing cardiovascular events. We aimed to investigate the effect of GLP1a on cardiovascular events in patients receiving ICIs.

Objective: Drug resistance and subsequent adverse effects, such as cancer cachexia, limit the clinical use of cisplatin. Oligonol® (Olg), a low-molecular-weight polyphenol, exhibits NF-κB inhibitory properties. NF-κB activation has been implicated in cisplatin resistance of cancer cells and skeletal muscle wasting.

Article Synopsis
  • EBV DNAemia surveillance is used to prevent post-transplant lymphoproliferative disorder (PTLD) in lung transplant recipients (LTRs), but its effectiveness in adult seropositive patients is unclear.
  • A study analyzed EBV viral loads in seropositive LTRs and compared levels between those who developed PTLD and those who didn't, revealing that peak viral loads were only significantly higher after PTLD was suspected.
  • The study found low positive predictive values (PPVs) for moderate (14.7%) and high-grade (33.3%) EBV DNAemia in indicating risk for future PTLD, suggesting improved diagnostic approaches are needed.

The order currently comprises five viral families with positive-sense RNA [(+)RNA] genomes that infect plants, fungi, and insects. Virion morphologies within the order differ between families, with icosahedral virions in the and filamentous virions in the other families. Despite their different morphologies, these viruses are placed in the same order based on phylogenetic analyses of replicase-associated polyproteins.

Poly(L-lactic acid) (PLLA) and poly(D,L-lactic acid) (PDLLA) particles have been applied as dermal fillers for soft-tissue augmentation because they can induce foreign-body reactions, resulting in fibroblast proliferation and collagen formation. Although PLLA and PDLLA fillers are safe and biocompatible, clinical complications such as nodules and granulomas have been reported, possibly due to incomplete reconstitution. PDLLA particles were prepared via emulsification in this study, and three stirring speeds were investigated when adding PDLLA into carboxymethyl cellulose solution.

is widely grown in tropical areas worldwide. Studies have demonstrated that extracts of its buds, leaves, and branches obtained through hydrodistillation, steam distillation, or solvent extraction exhibit physiological activities, including anti-melanogenic, antibacterial, and antioxidant properties; nevertheless, such extracts are mostly not effectively collected or adequately utilized. Accordingly, this study applied a rapid, effective, and easy-to-operate microwave-assisted water extraction (MAWE) technique for the first time to prepare leaf extract (MLE) with improved physiological activities.

Humans may inevitably be exposed to nanoplastics (NPls) through ingestion. The size of NPls significantly influences their absorption efficiency, so understanding behaviors of NPls during digestion is vital for risk assessment. In this study, fluorescent polystyrene (PS) and melamine-formaldehyde resin (MF) NPls were characterized by different techniques after the in vitro digestion process both with and without a standard food model, or with and without pH adjustment in the absence of the proteins.

Background: Shared decision-making (SDM) is crucial in healthcare to facilitate effective communication between providers and patients, aiding in making optimal medical decisions. Communication skills training (CST) can improve physicians' ability in SDM. However, SDM CST for medical students in Taiwan is scarce, and research comparing online versus in-person CST outcomes is lacking.

Amorphous oxide semiconductors (AOS) are pivotal for next-generation electronics due to their high electron mobility and excellent optical properties. However, InO, a key material in this family, encounters significant challenges in balancing high mobility and effective switching as its thickness is scaled down to nanometer dimensions. The high electron density in ultra-thin InO hinders its ability to turn off effectively, leading to a critical trade-off between mobility and the on-current (I)/off-current (I) ratio.

Introduction: Both cellular and humoral responses are important for vaccine protection, but recommendations on immunosuppressants in dermatology are largely based on pre-pandemic experiences. This study aimed to investigate the impacts of immunosuppressants on humoral and cellular immunogenicity to COVID-19 vaccinations in pemphigus patients.

Methods: SARS-CoV-2-naïve pemphigus patients and age-, and sex-matched healthy controls were recruited from multiple tertiary medical centers during 2021-2023.

2-deoxy-D-glucose (2DG) is a glucose analog converted to 2-deoxy-D-glucose-6-phosphate (2DG-6P) by hexokinase in glycolysis. While 2DG commonly measures glucose uptake, 2DG-6P detects glucose utilization. Here, we present a protocol to measure glucose utilization in various tissues after entering a mouse's body using radiolabeled 2DG.

SPINT1, a membrane-anchored serine protease inhibitor, regulates cascades of pericellular proteolysis while its tissue-specific functions remain incompletely characterized. In this study, we generate Spint1-lacZ knock-in mice and observe Spint1 expression in embryonic pancreatic epithelium. Pancreas-specific Spint1 disruption significantly diminishes islet size and mass, causing glucose intolerance and downregulation of MAFA and insulin.

Article Synopsis
  • Stereotactic arrhythmia radioablation (STAR) has shown effectiveness for treating refractory ventricular tachyarrhythmia (VT), with a focus on a Taiwanese patient group.
  • The study involved 11 patients, using advanced imaging techniques to treat VT with a single radiation dose, resulting in a significant 88% reduction in VT episodes within the first six months post-treatment.
  • Despite initial success, many patients experienced late VT recurrence, with a one-year survival rate of 83%, leading to some requiring additional treatments such as heart transplants or HeartMate III implantation.
