Increased Blood Flow and Tendon Swelling Precedes Vascular Expansion and Tissue Matrix Changes In Early Human Tendinopathy: A Potential Window for Superior Treatment Response

Advanced Science, EarlyView.
Human participants with early‐ or chronic‐stage tendinopathy and healthy controls are investigated using ultrasound Doppler, 3T and 7T MRI, and tendon biopsies. Tendon swelling and hyperperfusion are evident early, while vascular growth and extracellular matrix changes are most pronounced in chronic tendinopathy. Early intervention may provide superior

Early Detection of Chemotherapy‐Induced Glucose Metabolic Alterations in Bladder Carcinoma Using Deuterium (2H) Metabolic Imaging: in Vitro and in Vivo Assessments

Advanced Science, EarlyView.
This study presents the first application of deuterium metabolic imaging (DMI) for assessing therapeutic response in bladder cancer. Employing [2,3,4,6,6′‐2H5]‐D‐glucose, DMI successfully identified chemotherapy‐induced suppression of glycolysis both in vitro and in vivo.
