As she was asymptomatic and the degree of airway stenosis was small, treatment was not required for the hemangiomas, and left upper lobectomy for lung cancer was scheduled. After induction of general anesthesia, a regular tracheal tube was inserted under fiberoptic bronchoscopy, with care taken to prevent damage to the hemangiomas. An endobronchial blocker was inserted for

one-lung ventilation. The operation was performed uneventfully, and the tracheal tube was replaced postoperatively with a laryngeal mask airway while the patient was under deep anesthesia and neuromuscular blockade. The mask was removed after confirming lack of bleeding from the hemangiomas. No hypoxia or other complications occurred during or after the operation.”
“Wood selleck chemical of fast-growing hybrid find more poplars, consisting of six 6-year-old clones in one plantation in Quebec, was impregnated with methyl methacrylate (MMA) and then polymerized by heat/catalyst method. The mechanical properties (static

bending and compressive strength) of poplar clones and its MMA-hardened wood were investigated. Significant differences were observed among clones in bending and compression strength parallel to grain. Hardening treatment has also considerably improved all strength properties except for strain at rupture in static bending. The effects of density on mechanical properties were inconsistent, especially for hardened wood. Density was not the most important factor affecting strength properties. The improved properties of MMA-hardened hybrid poplar were comparable to some commercial hardwood species. (C) 2013 Elsevier B.V. All rights reserved.”
“Background: CK10 is a heterotetramer of type I and two type II keratins. Aim: This study examines selleck inhibitor the expression pattern of cytokeratin 10 (CK10) in human testis. Materials and methods: CK10 protein expression was examined using immunofluorescense

staining methods in 30 human testicular biopsy specimens (normal spermatogenesis, maturation arrest and Sertoli cell only syndrome, 10 cases each) obtained from patients undergoing investigations for infertility. Results: In the testis showing normal spermatogenesis, CK10 was expressed in the interstitium and in the seminiferous tubules. A strong cytoplasmic expression was seen in the Leydig cells, Sertoli cells, and spermatocytes. In testes showing spermatogenic arrest, weak CK10 protein expression was observed both in the interstitium and seminiferous tubules (some primary spermatocytes). In the testes showing Sertoli cell only syndrome, negligible CK10 staining was seen both in the seminiferous tubules and in the interstitial cells of Leydig. Conclusions: To the authors’ knowledge, this is the first study indicating CK10 expression in the human testis during normal and abnormal spermatogenesis. The varied expression of CK10 in testes showing abnormal spermatogenesis suggests its possible involvement in this process.
