Unveiling unique expression patterns of D20S16 satellite DNA in human embryonic development.

Satellite DNA is essential for chromosome stability and gene regulation, yet its specific roles in early human embryogenesis remain poorly defined. Here, we integrated the complete human genome reference (T2T-CHM13) with RNA-seq data to investigate the expression and regulation of the satellite DNA element D20S16 across key stages of human embryonic development. We identified 20 distinct D20S16 tandem repeat clusters, but found that only two, both located on chromosome 20, were actively transcribed during early embryogenesis.

Correlation between T cell immunity and the duration of EGFR-TKI resistance acquisition in patients harboring EGFR mutations.

Background: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) control lung cancer in patients with EGFR mutations, but resistance develops over time. Patients with high levels of genetic mutations rapidly acquire EGFR-TKI resistance. T cell immunity recognizes gene mutation products as neoantigens that effectively suppress mutation levels by eliminating clones with more mutations; this process is known as cancer immune editing.

Efficacy and Safety of First-Line Nivolumab Plus Ipilimumab in Patients with Postoperative Recurrent and Inoperable Non-Small Cell Lung Cancer: A Real-World Retrospective Observational Study.

The comparative efficacy and safety of nivolumab plus ipilimumab (Nivo-Ipi) combination therapy between patients with either postoperative recurrent non-small cell lung cancer (NSCLC) or inoperable stage III/IV NSCLC have yet to be conclusively determined. This retrospective study reviewed the medical records of consecutive patients diagnosed with either postoperative recurrent NSCLC or inoperable stage III/IV NSCLC. Both groups, referred to as the postoperative and inoperable cohorts respectively, underwent Nivo-Ipi therapy at four Japanese medical institutions between December 2020 and November 2022.

Beyond the Nucleus: Cytoplasmic Dominance in Follicular Thyroid Carcinoma Detection Using Single-Cell Raman Imaging across Multiple Devices.

Cytological diagnosis of follicular thyroid carcinoma (FTC) is one of the main challenges in the field of endocrine oncology due to the absence of evident morphological indicators. Morphological abnormalities in the nucleus are typically key indicators of cancer cytopathology and are attributed to a range of biochemical alterations in nuclear components. Consequently, Raman spectroscopy has been widely used to detect cancer in various cytological samples, often identifying biochemical changes prior to observable morphological alterations.

Prognostic factors of liver metastases in extensive-stage small cell lung cancer receiving chemo-immunotherapy.

Background: Chemoimmunotherapy combining platinum-based chemotherapy and etoposide with an anti-programmed death-ligand 1 (PD-L1) antibody is the standard treatment for patients with extensive-stage small cell lung cancer (ES-SCLC). However, the biomarkers that can predict outcomes after chemo-immunotherapy remain unclear. This study retrospectively investigated the prognostic factors after first-line chemoimmunotherapy in patients with ES-SCLC.

Metabolic tumor volume on F-FDG uptake as a negative predictor after ipilimumab plus nivolumab in advanced non-small cell lung cancer.

Study of -Acetylamino Saccharides with Synchrotron-Based Ultraviolet Resonance Raman Spectroscopy: In Combination with ATR Far-Ultraviolet Spectroscopy.

We investigate resonance (true resonance and pre-resonance) Raman (RR) effects in glucose, galactose, -acetylglucosamine, and -acetylgalactosamine with ultraviolet resonance Raman (UVRR) and far-ultraviolet (FUV) spectroscopies. Electronic transitions in the FUV region are attributed to electronic orbitals due to σ and π electrons. Their geometric orientations that participate in the resonance effect have not yet been well studied, unlike those for visible and near-infrared RR spectroscopies.

Efficacy and Safety of Amrubicin Monotherapy After Chemoradiotherapy in Patients With Relapsed Limited Disease Small-cell Lung Cancer.

Background/aim: Amrubicin is recognized as a second-line treatment for refractory small-cell lung cancer (SCLC) and is administered immediately after chemotherapy; however, it has not been evaluated in patients with recurrent SCLC following chemoradiotherapy (CRT). This study aimed to examine the activity and safety of amrubicin monotherapy in patients with relapsed SCLC previously treated with CRT.

Patients And Methods: This retrospective study evaluated patients with relapsed SCLC who had been previously treated with CRT, followed by amrubicin monotherapy between April 2007 and June 2021.

Attention network for predicting T-cell receptor-peptide binding can associate attention with interpretable protein structural properties.

Understanding how a T-cell receptor (TCR) recognizes its specific ligand peptide is crucial for gaining an insight into biological functions and disease mechanisms. Despite its importance, experimentally determining TCR-peptide-major histocompatibility complex (TCR-pMHC) interactions is expensive and time-consuming. To address this challenge, computational methods have been proposed, but they are typically evaluated by internal retrospective validation only, and few researchers have incorporated and tested an attention layer from language models into structural information.
