Comparison of the diagnostic accuracy between F-FAPI-04 PET/CT and F-FDG PET/CT in the clinical stage IA of lung adenocarcinoma.

Background: Fluorine 18-labeled fibroblast activation protein inhibitor (F-FAPI-04) positron emission tomography/computed tomography (PET/CT) has shown promise for the visualization of advanced stage lung cancer. The accuracy of F-FAPI-04 compared with that of fluorine-18 labeled-fluorodeoxyglucose (F-FDG) in detecting early lung adenocarcinoma (LUAD) remains unknown. Taking the surgical pathology of pulmonary nodule as the gold standard, the diagnostic performance of stage IA LUAD were compared between F-FAPI-04 PET/CT and F-FDG PET/CT, and the correlation between F-FAPI-04 uptake and pathological characteristics of stage IA LUAD.

Overexpression of Growth Differentiation Factor 15 Reduces Neuronal Cell Damage Induced by Oxygen-Glucose Deprivation/Reoxygenation via Inhibiting Endoplasmic Reticulum Stress-Mediated Ferroptosis.

Growth differentiation factor 15 (GDF15) can be induced under various stress conditions. This study aimed to explore the role of GDF15 in oxygen-glucose deprivation/reoxygenation (OGD/R)-induced HT22 cells. OGD/R was employed to induce the HT22 cell model, and GDF15 expression was upregulated via transfection.

Transcriptomic and proteomic features of a mouse model of sperm DNA damage induced by benzo(a)pyrene.

This study replicated a mouse model of sperm DNA damage induced by benzo(a)pyrene (BaP), and the transcriptomic and proteomic features of the model were examined to clarify the pathways related to BaP-induced damage to sperm DNA. Male mice in the BaP group were subjected to BaP at a dosage of 100 mg/kg/d or an equivalent quantity of saline solution in the control group for 60 days. Subsequently, the DNA fragmentation index (DFI) in sperm was assessed using a sperm chromatin structure assay (SCSA).

NAD (P)H Quinone Dehydrogenase 1-Targeting Triptolide Analogue Causes Tumor Regression and Sensitizes Cisplatin-Resistant Lung Cancer to Chemotherapy.

Cisplatin (DDP) is a first-line chemotherapeutic drug against lung cancer. Nonetheless, the effectiveness of this drug is hampered by drug resistance. Overcoming drug resistance is crucial for improving the outcomes of lung cancer treatment.

Solid Boundary Output Feedback Control of the Stefan Problem: The Enthalpy Approach.

By taking enthalpy-an internal energy of a diffusion-type system-as the system state and expressing it in terms of the temperature profile and the phase-change interface position, the output feedback boundary control laws for a fundamentally nonlinear single-phase one-dimensional (1-D) PDE process model with moving boundaries, referred to as the Stefan problem, are developed. The control objective is tracking of the spatiotemporal temperature and temporal interface (solidification front) trajectory generated by the reference model. The external boundaries through which temperature sensing and heat flux actuation are performed are assumed to be solid.

The miR-430 locus with extreme promoter density forms a transcription body during the minor wave of zygotic genome activation.

In anamniote embryos, the major wave of zygotic genome activation starts during the mid-blastula transition. However, some genes escape global genome repression, are activated substantially earlier, and contribute to the minor wave of genome activation. The mechanisms underlying the minor wave of genome activation are little understood.
