Cholestasis instantly improved in 82% of the patients. After a long-term follow-up of median 33 months (range 3-149), 28 of the patients (76%) required no further intervention for recurring biliary obstruction following HJS. Anastomotic strictures were observed in six (16%), recurring biliary concrements in two patients (5%).

Conclusion: HJS did prevent recurrent biliary obstruction in the majority of the patients. We therefore

recommend early HJS for complicated post-transplant biliary tract obstruction not treatable by a limited number of endoscopic AZD1480 supplier interventions.”
“We present the material alpha-omega-bis-(dicyanovinylen)-sexithiophen (DCV6T) as donor material in organic solar cells. A systematic study on the potential of DCV6T is given for different active layer concepts. DCV6T is a member of a class of acceptor-substituted oligothiophenes, which showed efficiencies of up to 3.4% and open circuit voltages (V(oc)) of 1.0 V, which were recently BKM120 clinical trial reported [K. Schulze Adv. Mater. (Weinheim, Ger.) 18, 2875 (2006)]. To verify the potential of the material (DCV6T), organic solar cells with planar heterojunctions, bulk heterojunctions, and a hybrid-planar-mixed heterojunction are investigated. The planar heterojunction

solar cells of DCV6T and C60 show the highest V(oc) of 0.90 V. The mixed heterojunction solar cells have improved currents but a lower V(oc) of 0.82 V. The solar cell using the hybrid-planar-mixed heterojunction achieves the best combination of parameters. It has

a V(oc) of 0.88 V, a short circuit current (j(sc)) of 5.7 +/- 0.4 mA cm(-2), a fill factor of 41.6%, and a power conversion efficiency of 2.1 +/- 0.2%.”
“Background There are various therapeutic SB202190 price options for the treatment of pyogenic granuloma (PyG), but the results are frequently unsatisfactory, especially at difficult sites and with extensive lesions. Objective To evaluate the success of treatment of PyG using the 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and to compare it with state-of-the-art treatment methods. Materials and Methods Twenty patients with PyG were treated using the long-pulsed 1,064-nm Nd:YAG laser with fluences of 60 to 180 J/cm2, a spot size of 7 mm, and a pulse duration of 40 ms. One to four treatment sessions were necessary for complete removal. Results Recurrence-free healing occurred in 19 of 20 patients (follow-up = 6 months, maximum 22 months). Because of heavy bleeding, one nonresponder was successfully treated using a carbon dioxide laser. The cosmetic results were good; textural changes of the skin were slight, if present at all. Conclusion When used with the right strategy and patient cohort, the long-pulse 1,064-nm Nd:YAG laser is an effective, low-risk, minimally invasive method of treating PyG.
