Non-small cell lung cancer (NSCLC) is a highly aggressive malignancy frequently driven by oncogenic mutations in the epidermal growth factor receptor (EGFR). Although EGFR-tyrosine kinase inhibitors (EGFR-TKIs) have shown clinical efficacy, challenges such as limited response duration and intrinsic mechanisms-such as EGFR amplification-can affect therapeutic outcomes. This study investigates the role of the USP21-EGFR-Lyn axis in NSCLC progression, identifying USP21 as a key regulator of EGFR and Lyn stability.

We developed METACANS, an multimodal artificial intelligence (AI) model that integrates WSIs with clinicopathological features to predict ALN metastasis. METACANS was trained on 1991 cases and externally validated across five cohorts with a total of 2166 cases.

The emerging role of ubiquitin-specific peptidase 21 (USP21) in stabilizing Fra-1 (FOSL1) highlights its involvement in promoting colorectal cancer (CRC) metastasis. Additionally, a reciprocal link between EGFR signaling and Fra-1 activation has been identified, mediated through matrix metalloproteinases (MMPs). However, the functional implications of the USP21-EGFR signaling axis in metastatic CRC (mCRC) are not fully understood.

EVD management practice among institutions and practitioners varies greatly, with little evidence supporting ideal ICP recording and CSF drainage practice.
Objective: This study's aim is to determine variations in ICP across 21 min before and after CSF drainage.
This study explored the use of waste from the textile industry (silkworm byproducts) as a promising raw feedstock for the production of carbon-based adsorbents (biochar). The silk excreta biochar generated at 600 and 700 °C (referred to as SEB-600 and SEB-700, respectively) were evaluated in terms of their efficacy in adsorbing cationic (methylene blue) and anionic (Congo red) textile dyes. Although the functional groups on the surfaces of SEB-600 and SEB-700 were not significantly different, the specific surface area of SEB-700 was greater than that of SEB-600.

Currently, no available biomarkers can promptly predict responses to platinum-based treatment. Therefore, we developed the Pathologic Risk Classifier for HGSOC (PathoRiCH), a histopathologic image-based classifier.

The focus was on transforming waste into energy resources through pyrolysis under CO conditions. In one-stage pyrolysis, the evolution of syngas under N was found to be comparable to that under CO.

Indeed, heterogeneous matrix of plastic wastes makes them hard to be disposed. As such, this study aimed to introduce an environmentally benign/reliable disposal platform for complete decomposition of plastic wastes.

Since an invention of synthetic fibers (textiles), our life quality has been improved. However, the cumulative production and disposal of them have perceived as significant since they are not biodegradable and hard to be upcycled/recycled. From washing textiles, microplastics are released into the environment, which are regarded as emerging contaminants.

PTCL-NOS was further classified into nodal PTCL with follicular helper T cell (Tfh) phenotype ("PTCL-Tfh_new") and "PTCL-NOS_new". PD-1 and PD-L1 expression on tumor cells and reactive immune cells was evaluated using immunohistochemistry.

Methods: Changes in glycolysis-related molecules and glycolytic activity were evaluated in PD-L1 and PD-L1 NSCLC cells after transfection or knockdown of PD-L1, respectively. Jurkat T-cell activation was assessed after co-culture with NSCLC cells.
The MET tyrosine receptor kinase is essential for embryonic development and tissue regeneration by promoting cell survival, proliferation, migration, and angiogenesis. It also contributes to tumor development and progression through diverse mechanisms. Using human cancer cell lines, including Hs746T (-mutated/amplified), H596 (-mutated), and H1993 (-amplified) cells, as well as BEAS-2B bronchial epithelial cells, we investigated whether MET is involved in the regulation of immune checkpoint pathways.

Next-generation sequencing (NGS)-based cancer panel tests are actively being applied in the clinic for precision oncology. Given the importance of NGS panel tests in the palliative clinical setting, it is critical to understand success rates, factors responsible for test failures, and the incidence of clinically meaningful genetic alterations. We performed NGS cancer panel test with tumors from the stomach (n = 234), colorectum (n = 196), and rare tumors (n = 105) from 535 recurrent or metastatic cancer patients for 1 year.

Rationale: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic malignancy. This disease almost always presents with cutaneous involvement.
Patient Concerns: The 1st patient was a 16-year-old girl who presented with recurrent epistaxis.
Objective: To evaluate bronchovascular injuries as the causative occurrence for clinically significant hemoptysis after percutaneous transthoracic needle biopsy (PTNB).
Materials And Methods: We included 111 consecutive patients who experienced hemoptysis after cone beam CT (CBCT)-guided PTNB from January 2014 through January 2017. Clinically significant hemoptysis was defined as hemoptysis causing hemodynamic instability or oxygen desaturation greater than 10% of baseline.
Objectives: Endoplasmic reticulum (ER) stress is associated with tumor development and progression via pro-tumorigenic and anti-tumorigenic effects. However, the clinicopathological implications of the ER stress pathway in non-small cell lung cancer remain unclear. Therefore, we sought to address these issues in this study.
