Combretastatin A4 phosphate has tumor antivascular activity in rat and man as demonstrated by dynamic magnetic resonance imaging.
PURPOSE Combretastatin A4 phosphate (CA4P) is a novel vascular targeting agent. Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) studies were performed to examine changes in parameters… Expand

Evaluation of the anti‐vascular effects of combretastatin in rodent tumours by dynamic contrast enhanced MRI
The anti‐vascular effects of the tubulin binding agent, disodium combretastatin A‐4 3‐O‐phosphate (CA‐4‐P), have been investigated in the rat P22 carcinosarcoma by measurements of radiolabelled… Expand

A comparison of DNA damage in testicular and proximal epididymal spermatozoa in obstructive azoospermia.
Testicular and epididymal spermatozoa are used routinely for intracytoplasmic sperm injection (ICSI) to treat men with obstructive azoospermia. Little is known of the effects of obstruction and… Expand

Preclinical evaluation of the fluorinated 2-nitroimidazole N-(2-hydroxy-3,3,3-trifluoropropyl)-2-(2-nitro-1-imidazolyl) acetamide (SR-4554) as a probe for the measurement of tumor hypoxia.
A novel probe, N-(2-hydroxy-3,3,3,-trifluoropropyl)-2-(2-nitro-1-imidazolyl) acetamide (SR-4554), has been used to detect tumor hypoxia noninvasively by 19F magnetic resonance spectroscopy (19F MRS).… Expand

Validation of the fluorinated 2-nitroimidazole SR-4554 as a noninvasive hypoxia marker detected by magnetic resonance spectroscopy.
PURPOSE Tumor hypoxia is associated with poor prognosis and a more malignant tumor phenotype. SR-4554, a fluorinated 2-nitroimidazole, is selectively bioreduced and bound in hypoxic cells. We present… Expand
