A Simple and Sensitive LC-MS/MS Method for the Determination of Mobocertinib and Its Metabolite Desmethyl-Mobocertinib in Human Plasma and Its Application to Clinical Pharmacokinetic Study.

Mobocertinib is a potent selective tyrosine kinase inhibitor approved for the treatment of non-small cell lung cancer with activating EGFR exon 20 insertions. The aim of this study was to develop a procedure for liquid chromatography tandem mass spectrometry (LC-MS/MS) for the determination of mobocertinib and its metabolite desmethyl-mobocertinib in human plasma. The human plasma samples were precipitated with acetonitrile and analyzed using a Waters ACQUITY BEH C column coupled to a triple quadrupole mass spectrometer.

The Role of STEAP3 in Pathogenesis of Gliomas: An Independent Prognostic Factor and Regulator of Ferroptosis.

Objective: Gliomas are common intracranial tumors with high malignancy and poor prognosis, classified into glioblastomas (GBM) and low-grade glioma (LGG). However, the regulatory mechanisms of glioma tumorigenesis remain unclear. This study aimed to investigate the role of six-transmembrane epithelial antigen of the prostate 3 (STEAP3) in glioma prognosis and explore its potential as a therapeutic target, as well as the ferroptosis-related molecular mechanism in progression of gliomas.

Deciphering the role of heat shock protein HSPA1L: biomarker discovery and prognostic insights in Parkinson's disease and glioma.

Background: Heat shock proteins (HSPs) play a critical role in cellular stress responses and have been implicated in numerous diseases, including Parkinson's disease (PD) and various cancers. Understanding the differential expression and functional implications of HSPs in these conditions is crucial for identifying potential therapeutic targets and biomarkers for diagnosis and prognosis.

Methods: We utilized combined datasets (GSE6613 and GSE72267) to identify and analyze the heat shock-related genes differentially expressed in PD.

Unveiling the therapeutic prospects of IFNW1 and IFNA21: insights into glioma pathogenesis and clinical significance.

Glioma, a type of brain tumor, poses significant challenges due to its heterogeneous nature and limited treatment options. Interferon-related genes (IRGs) have emerged as potential players in glioma pathogenesis, yet their expression patterns and clinical implications remain to be fully elucidated. We conducted a comprehensive analysis to investigate the expression patterns and functional enrichment of IRGs in glioma.

Preliminary Study: 3D Nailing for Intertrochanteric Femur Fractures.

Objective: This study introduced the structural features of the Three-Dimensional Proximal Femoral Nail (3DPFN), a patented invention, and highlights its advantages in treating intertrochanteric fractures of the femur. Furthermore, biomechanical comparative experiments validated the biomechanical performance of 3DPFN in treating Evans-Jensen type IV intertrochanteric fractures.

Methods: Evans-Jensen type IV intertrochanteric fracture models were created using artificial femurs produced by the American company Sawbone.

The impact of plate length, fibula integrity and plate placement on tibial shaft fixation stability: a finite element study.

Background: Tibial shaft fractures account for approximately 15% of long bone fractures. Locked plates with minimally invasive plate osteosynthesis techniques are used widely by surgeons. The purpose of this study is to investigate the impact of factors meaning the plate length, fibula integrity, and placement of the plate on the stability of tibial shaft fracture fixation.
