High‐altitude headache: Insights into pathophysiology and potential treatment implications

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude headache occurs during prolonged exposure to low oxygen, such as during ascent to high altitude. Several risk factors increase its likelihood, with the degree of hypoxia, often driven by rapid ascent to greater altitudes, being the most prominent factor.

PrEP at the site of action in cisgender and transgender women: A pharmacology study of blood and rectal CD4+ lymphocytes

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2949-2959, August 2026.
Background Female sex hormones used in feminizing hormone therapy (FHT) may influence activation and persistence of HIV pre‐exposure prophylaxis (PrEP) medications. The clinical relevance of this interaction remains unclear, particularly for transgender and cisgender women (TGW and CGW).

5'-Nucleotidases: specific assays for five different enzymes in cell extracts [PDF]

, 2002
Several mammalian 5'-nucleotidases (5-NTs), attached to membranes or present in the cytosol or in mitochondria, remove the phosphate from ribo- and deoxyribonucleotides with different specificities for the sugar and base moieties.

The evolving landscape of the Warburg effect in gastric cancer: From molecular mechanisms to targeted therapy

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
Hypoxia, oncogenic signaling, transcriptional and epigenetic remodeling, and H. pylori–microbiota interactions drive the Warburg effect in gastric cancer. Enhanced glycolysis and lactate export support biosynthesis, remodel the tumor microenvironment, promote stromal activation and immune suppression, and reveal actionable biomarkers and therapeutic ...
