Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

Experimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, Volume 158, Issue 12, Page 3217-3231, 15 June 2026.
What's new? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison

Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

Head &Neck, Volume 48, Issue 6, Page 1620-1629, June 2026.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.

FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3309-3321, June 2026.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...
