Intraoperative EEG monitoring is increasingly used during aortic arch procedures for early detection of acute neurologic dysfunction. In those procedures involving cardiopulmonary bypass, increased neuroprotection may be gained by using hypothermic circulatory arrest and selective cerebral perfusion. Several techniques for cerebral perfusion exist; yet no studies have noted distinct EEG ...

An intravenous leiomyomatosis is a rare benign smooth muscle tumor originating from myometrial veins. The leiomyomatosis occasionally extends from the pelvic vein into the right cardiac chambers. A pelvic arterio-venous fistula (AVF) is also a rare pelvic vascular malformation. The massive arterio-venous shunting causes high output cardiac failure. We present ...

Maternal nutrient restriction and decreased scotophase concentrations of melatonin have been associated with severely compromised pregnancies. We hypothesized that melatonin supplementation in a compromised pregnancy enhances the bradykinin (BK)-induced relaxations of placental arteries thereby ensuring sufficient umbilical blood flow to the developing fetus. Pregnant ewes (n = 31) were fed an adequate ...

Acute peripheral arterial thrombosis can be threatening to life and limb. Dissolution of the thrombus local catheter-directed intra-arterial infusion of fibrinolytic agents such as urokinase is the standard therapy for thrombosis; however, this method is time-intensive, and amputation of the affected limb is still needed in 10-30% of cases. Furthermore, ...

A major limitation in the pharmacological treatment of pulmonary arterial hypertension (PAH) is the lack of pulmonary vascular selectivity. Recent studies have identified a tissue-penetrating homing peptide, CARSKNKDC (CAR), which specifically homes to hypertensive pulmonary arteries but not to normal pulmonary vessels or other tissues. Some tissue-penetrating vascular homing peptides ...
