A 50 yo female with PSC and a bleeding duodenal varix (DV) was evaluated for possible enbucrilate therapy. Endoscopically (Figure 1), the DV was high risk for rebleeding but the relative in-flow and out-flow were uncertain. CT (Figure 2) showed portal vein thrombosis (PVT) and the vascular anatomy of the DV to consist of inflow from the superior mesenteric vein (SMV) with outflow through the DV...

Polymer, heal thyself! Supramolecular ABA triblock copolymers formed by dimerization of 2-ureido-4-pyrimidinone (UPy) end-functionalized polystyrene-b-poly(n-butyl acrylate) (PS-b-PBA) AB diblock copolymers have been synthesized, resulting in a self-healing material that combines the advantageous mechanical properties of thermoplastic elastomers and the dynamic self-healing features of supramol...

The chemistry, photostability and mechanism of action of ultraviolet filters are reviewed. The worldwide regulatory status of the 55 approved ultraviolet filters and their optical properties are documented. The photostabilty of butyl methoxydibenzoyl methane (avobenzone) is considered and methods to stabilize it in cosmetic formulations are presented.

OBJECTIVE Twin-twin transfusion syndrome is a serious obstetric complication unique to monochorionic twin gestations. Occlusion of vessel anastomoses is recommended to improve the perinatal outcome. CASE REPORT A 36-year-old, gravida 1, woman had a monochorionic twin pregnancy which was found to be affected by twin-twin transfusion syndrome at 26 weeks' gestation. The condition was successful...

We report a case of intrarenal pseudoaneurysm of the right kidney after percutaneous nephrolithotomy (PCNL) in supine position. Diagnosis was established by angiotomography with a 3-D reconstruction. Treatment was successfully achieved by endovascular occlusion using N-butyl-2-cyanoacrylate.

A 2D tri-layer compound {[Co(8)(tbip)(6)(H(2)O)(9)(OH)(4)]·12(H(2)O)}(n) (1) (H(2)tbip = 5-tert-butyl isophthalic acid) consisting of novel heptacobaltate clusters and single cobalt centers bridged by tbip(2-) ligands has been hydrothermally synthesized. The complex represents a rare example of a homometallic coordination polymer built up from both heptanuclear metal clusters and single metal c...
