Ischemia and reperfusion (IR) are known to negatively affect early allograft function following solid organ transplantation. Lipocalin-2 (Lcn-2) has been described as a marker and potential positive modulator of acute inflammation during these processes. Using a heterotopic murine heart transplant model we previously found that IR resulted in a pronounced(More)
Minimally invasive lung lobectomy was introduced in the late 1990s. Since that time, various different approaches have been described. At our institution, two different minimally invasive approaches, a robotic and a conventional thoracoscopic one, were performed for pulmonary lobectomies. This study compares perioperative outcome of the two different(More)
Lipocalin 2 (Lcn2) is rapidly produced by damaged nephron epithelia and is one of the most promising new markers of renal injury, delayed graft function and acute allograft rejection (AR); however, the functional importance of Lcn2 in renal transplantation is largely unknown. To understand the role of Lcn2 in renal AR, kidneys from Balb/c mice were(More)
BACKGROUND Simultaneous pancreas-kidney (SPK) transplantation is widely accepted as an optimal therapeutic option for patients with type 1 diabetes mellitus (T1DM) and end-stage renal disease, but the indication for patients with type 2 diabetes mellitus (T2DM) is still controversially discussed. METHODS Twenty-one T2DM recipients of a first combined(More)
Lipocalin-2 (Lcn-2) is expressed in human neutrophils and epithelial cells, particularly in the presence of inflammation or cancer. It was shown to be highly expressed in various human cancers. Increased protein levels were associated with decreased survival of patients with breast or gastric cancer. The main focus of this work was to analyze the(More)
Diamine oxidase (DAO, EC 1.4.3.6) is the major enzyme degrading histamine and other biogenic amines [1, 2]. Although DAO activity has been reported for various mammalian tissues, very little is known about the cellular and subcellular distribution of the enzyme. Therefore, we employed a combination of DAO activity assays, immunoblotting with an anti-DAO(More)
Dear Editor: Muscular pelvic floor defects, which can occur after pelvic tumor resection, require primary repair in order to avoid perineal herniation of abdominal contents. Small defects can be repaired with direct approximation of tissue or with gracilis muscle flaps. For large defects formation of either bilateral gluteus maximus advancement myocutaneous(More)
Lipocalin-2 (Lcn2) expression contributes to ischemia and reperfusion injury (IRI) by enhancing pro-inflammatory responses. The aim of this work was to elucidate the regulation of Lcn2 during hypoxia and its effects on the expression of key chemokines and adhesion molecules. Lcn2 wt and Lcn2(-/-) mice were used in a heterotopic heart transplantation model.(More)
To analyze causes, predictors and consequences of conversions from intended VATS lobectomy to open surgery. This is a retrospective analysis of a prospectively maintained database. From 2009 until December 2012, 232 patients were scheduled for anatomical VATS resection. Conversion to open surgery was necessary in 15 (6.5 %) patients. Reasons for conversion(More)
The aim of the present study was to analyze feasibility, morbidity, mortality, and oncologic outcome of extended video-assisted thoracoscopic surgery (VATS) anatomic lung resections in a single-center experience. Extended resections include bilobectomies, bronchoplasties, and pneumonectomies. The present study is a retrospective analysis of a prospectively(More)
