Stability of the thromboxane B biomarker of low-dose aspirin pharmacodynamics in human whole blood and in long-term stored serum samples.

Background: Serum thromboxane B (sTXB) is a validated biomarker of low-dose aspirin pharmacodynamics. In the original method, nonanticoagulated blood samples must be incubated at 37 °C immediately after withdrawal, centrifuged and serum supernatant should be frozen until assayed. Timely completion of all preanalytical steps may affect the feasibility and quality of sTXB measurements.

Sustaining surgeon longevity in spine surgery: A narrative review.

Spine surgery is a physically and mentally demanding surgical specialty. This paper focuses on raising awareness about ergonomic challenges that threaten spine surgeon longevity. Sustaining a fulfilling career in spine surgery requires a multifaceted approach that prioritizes physical well-being and mental health.

17β-estradiol inhibits Notch1 activation in murine macrophage cell line RAW 264.7.

Background: Macrophages are major effectors in regulating immune response and inflammation. The pro-inflammatory phenotype (M1) is induced by the activation of the Toll-like receptor 4 (TLR4) on the macrophage surface, which recognizes lipopolysaccharide (LPS), a component of Gram-negative bacterial wall, and by the binding of interferon-gamma (IFNγ), a cytokine released by activated T lymphocytes, to its receptor (IFNGR). Among the pathways activated by LPS/IFNγ is the Notch pathway, which promotes the M1 phenotype.

Personalized Treatment Strategies via Integration of Gene Expression Biomarkers in Molecular Profiling of Laryngeal Cancer.

Laryngeal cancer poses a substantial challenge in head and neck oncology, and there is a growing focus on customized medicine techniques. The present state of gene expression indicators in laryngeal cancer and their potential to inform tailored therapy choices are thoroughly examined in this review. We examine significant molecular changes, such as TP53, CDKN2A, PIK3CA, and NOTCH1 mutations, which have been identified as important participants in the development of laryngeal cancer.
