Abstract
BACKGROUND To evaluate the trends in indications for penetrating keratoplasty (PKP) in Homburg/Saar between 2001 and 2010. METHODS Retrospective review of 1,200 corneal buttons which underwent PKP that were performed between 2001 and 2010 at the Department of Ophthalmology of Saarland University Hospital, Germany. Indications were classified into eight different groups following histological analysis: keratoconus, Fuchs' dystrophy, bullous keratopathy, corneal scars, keratitis, regraft, corneal dystrophy other than Fuchs' dystrophy, and other diagnoses. Two different time periods (between 2001-2005 and between 2006-2010) were analyzed. RESULTS Keratoconus (25.5 %) was the most common indication for PKP in our study, followed by Fuchs' dystrophy (21.2 %), bullous keratopathy (14.6 %), corneal scars (14.4 %), keratitis (13.0 %), regraft (7.0 %), non-Fuchs' dystrophies (2.1 %), and other diagnoses (2.3 %). Comparing the two different time periods, a trend of significantly increasing frequency of keratoconus and Fuchs' dystrophy, and a decreasing frequency of corneal scars, were found as indications for PKP in our study. CONCLUSIONS Keratoconus was the leading indication for PKP in our series, and had a significantly increasing trend from 2001-2005 to 2006-2010. The percentage of patients with Fuchs' dystrophy increased, and became the second most common indication for PKP, while the number of PKPs for corneal scars decreased during the last 5 years in our institution.

Abstract
The molecular carcinogenesis of lung cancer has yet to be clearly elucidated. We investigated the possible oncogenic function of SEC62 in lung cancer, which was predicted based on our previous findings that lung and thyroid cancer tissue samples exhibited increased Sec62 protein levels. The SEC62 gene locus is at 3q26.2, and 3q amplification is reportedly the most common genomic alteration in non-small cell lung cancer. We analyzed SEC62 mRNA and protein levels in tissue samples from lung cancer patients by real-time quantitative PCR, Western blot, and IHC and found significantly increased SEC62 mRNA and protein levels in tumors compared with tumor-free tissue samples from the same patients. Correlation analyses revealed significantly higher Sec62 levels in tumors with lymph node metastases compared with nonmetastatic tumors, as well as in poorly compared with moderately differentiated tumors. On the basis of these promising results, we examined the role of Sec62 in cancer cell biology in vitro. Cell migration assays with lung and thyroid cancer cells showed distinct stimulation of migration in SEC62-overexpressing cells and inhibition of migration in Sec62-depleted cells. Moreover, we found that SEC62 silencing sensitized the cells to thapsigargin-induced endoplasmic reticulum stress. Thus, our results indicate that SEC62 represents a potential candidate oncogene in the amplified 3q region in cases of non-small cell lung cancer and harbors various functions in cancer cell biology.

Abstract
BACKGROUND Genetically modified chondrocytes embedded in alginate improve cartilage repair in experimental models, and alginates are clinically used for articular chondrocyte transplantation. In the present study, we tested the hypothesis that the alginate system allows for sustained transgene expression in cartilage defects in a preclinical large animal model in vivo. METHODS Primary cultures of ovine articular chondrocytes were transfected with the Photinus pyralis luc or the Escherichia coli lacZ genes in monolayer culture in vitro using eight different nonviral compounds. Optimally transfected chondrocytes were encapsulated in spheres composed of nonbiomedical or biomedical grade alginates for evaluation of luciferase expression, cell numbers and viabilities in vitro. Transfected chondrocytes encapsulated in spheres comprised of the different alginates were then implanted into osteochondral defects in the knee joints of sheep to examine the profiles of transgene expression in vivo. RESULTS Ovine articular chondrocytes were efficiently transfected with FuGENE 6. Transgene expression was detectable after encapsulation in the alginates over 21 days in vitro. Transplantation of genetically modified chondrocytes to cartilage defects in vivo resulted in maximal transgene expression on day 1 after transfection, with a decrease by day 21, the longest time point evaluated. Remarkably, the reduction in luciferase activity was less pronounced when biomedical grade alginates were employed, compared to nonbiomedical grade alginates, suggesting that such alginates might be better suited to support elevated transgene expression after transplantation of genetically modified chondrocytes. CONCLUSIONS This approach may be of value to study the effects of potential therapeutic genes upon cartilage repair in a clinically relevant setting.

Abstract
BACKGROUND & AIMS The insulin-like growth-factor 2 (IGF2) mRNA binding protein p62 is highly expressed in hepatocellular carcinoma tissue. Still, its potential role in liver disease is largely unknown. In this study, we investigated pathophysiological implications of p62 overexpression in mice. METHODS We generated mice overexpressing p62 under a LAP-promotor. mRNA expression levels and stability were examined by real-time RT-PCR. Allele-specific expression of Igf2 and H19 was assessed after crossing mice with SD7 animals. The Igf2 downstream mediators pAKT and PTEN were determined by Western blot. RESULTS Hepatic p62 overexpression neither induced inflammatory processes nor liver damage. However, 2.5week old transgenic animals displayed a steatotic phenotype and improved glucose tolerance. p62 overexpression induced the expression of the imprinted genes Igf2 and H19 and their transcriptional regulator Aire (autoimmune regulator). Neither monoallelic expression nor mRNA stability of Igf2 and H19 was affected. Investigating Igf2 downstream signalling pathways showed increased AKT activation and attenuated PTEN expression. CONCLUSIONS The induction of a steatotic phenotype implies that p62 plays a role in hepatic pathophysiology.

Abstract
OBJECTIVE To report the case and surgical therapy of a patient with bilioptysis after vaginal delivery, caused by bronchobiliary fistula. Histologic analysis revealed endometrial glands embedded in the decidual stroma neighboring the liver and the lung. DESIGN Case report. SETTING University hospital. PATIENT(S) A 39-year-old patient, 7 days after vaginal delivery, without endometrial history. INTERVENTION(S) Synchronous liver and lung resection of a bronchobiliary fistula by laparotomy and a transdiaphragmatic approach. MAIN OUTCOME MEASURE(S) For complicated brochobiliary fistula caused by endometriosis, radical surgical treatment is mandatory. RESULT(S) Histopathologic analyses confirmed the presence of clusters of endometrial glands embedded in the decidual stroma that were neighboring the liver, and perifistulous lung tissue was shown to contain biliary pigment absorbed by macrophages and their derivatives. CONCLUSION(S) Hepatic and perihepatic endometriosis can cause a bronchobiliary fistula. Exacerbation of the symptoms can be triggered by high estrogen levels, physiologically dominating the last trimester. For such a rare case, surgery is mandatory.

Abstract
Respiratory Distress Syndrome (RDS) is a common complication in preterm neonates. If RDS is not responding to conventional treatment modalities (surfactant therapy, ventilatory support, etc.), an underlying pathology (pulmonary lymphangiectasia, capillary alveolar dysplasia, alpha-1 antitrypsin deficiency, etc.) other then prematurity should be taken into consideration.Here, we report on a preterm neonate with the unusual simultaneous occurrence of pulmonary and systemic lymphangiectasia and homozygous alpha-1 antitrypsin deficiency who developed severe RDS that was refractory to conventional treatment. The diagnostic and therapeutic approach in this patient is presented.

Abstract
Calpains, also called calcium activated neutral proteases (CANP), are expressed ubiquitously. They are intracellular, non-lysosomal cytoplasmic cysteine endopeptidases. Calcium is required for their activation. Their endogenous specific inhibitor is calpastatin, which is expressed ubiquitously and coexists within cells besides calpain. When calcium is present, calpastatin and calpain attach to each other inhibiting the protease. The calpain system plays an important role in many processes including apoptosis, necrosis, ischemia formation and exocytosis. So far, many reports exist on studies about the influence of calpains in different tumors (skin, breast, renal cell and prostate cancers). The role of calpains in pathogenesis or further tumor progression has always been proved in related studies, but their exact function could not be demonstrated. So far, no studies on calpains being involved in the pathogenesis of ovarian cancer have been published. In our study we focused on the expression of the enzymes calpain 1, calpain 2 and their inhibitor calpastatin in normal and malign ovarian tissue. Therefore, we performed immunohistochemical stainings of paraffin slices and evaluated staining intensity (SI), percentage of positive cells (PP) and immunoreactive score (IRS). We evaluated the correlation between enzyme expression in malign and benign ovarian tissues. In malignant ovarian tissue, we found decreased expression, staining intensity and immunoreactive score of calpastatin. With higher grading of the ovarian carcinoma, staining intensity and immunoreactive score of calpain 1 decreased. Staining intensity of calpain 2 in ovarian carcinoma decreased with increasing lymph node status. We clearly demonstrated differences between enzyme expressions in malign and benign tissue. This study could not find any specific function of calpains. Only few studies in the literature have been found that deal with calpain evaluation of ovarian cancer. Additional studies including more patients are required to elucidate the functional role and impact of calpain in tumors in detail.

Abstract
Structural data about the human lung fine structure are mainly based on stereological methods applied to serial sections. As these methods utilize 2D images, which are often not contiguous, they suffer from inaccuracies which are overcome by analysis of 3D micro-CT images of the never-sectioned specimen. The purpose of our study was to generate a complete data set of the intact three-dimensional architecture of the human acinus using high-resolution synchrotron-based micro-CT (synMCT). A human lung was inflation-fixed by formaldehyde ventilation and then scanned in a 64-slice CT over its apex to base extent. Lung samples (8-mm diameter, 10-mm height, N = 12) were punched out, stained with osmium tetroxide, and scanned using synMCT at (4 μm)(3) voxel size. The lung functional unit (acinus, N = 8) was segmented from the 3D tomographic image using an automated tree-analysis software program. Morphometric data of the lung were analyzed by ANOVA. Intra-acinar airways branching occurred over 11 generations. The mean acinar volume was 131.3 ± 29.2 mm(3) (range, 92.5-171.3 mm(3)) and the mean acinar surface was calculated with 1012 ± 26 cm(2). The airway internal diameter (starting from the bronchiolus terminalis) decreases distally from 0.66 ± 0.04 mm to 0.34 ± 0.06 mm (P < 0.001) and remains constant after the seventh generation (P < 0.5). The length of each generation ranges between 0.52 and 0.93 mm and did not show significant differences between the second and eleventh generation. The branching angle between daughter branches varies between 113-degree and 134-degree without significant differences between the generations (P < 0.3). This study demonstrates the feasibility of quantitating the 3D structure of the human acinus at the spatial resolution readily achievable using synMCT.

Abstract
BACKGROUND The apoE-/-/LDL-/- double knockout mice are bearing considerable structural homology to human atherosclerosis. We hypothesized, that advanced lesion formation in the renal artery is associated with kidney alterations in these mice. METHODS Kidneys from apoE-/-/LDL-/- double knockout mice at the age of 80 weeks (n = 6) and C57/BL control mice (n = 5) were infused with Microfil, harvested and scanned with micro-CT (12 mum cubic voxels) and Nano-CT (900 nm cubic voxels). We quantitated the total vascular volume using micro-CT. Number and cross-sectional area (microm2) of glomeruli were measured using histology. RESULTS At the age of 80 weeks, the renal total vascular volume fraction decreased significantly (p < 0.001) compared to controls. Moreover, the renal artery showed advanced atherosclerotic lesions with adventitial Vasa vasorum neovascularization. Perivascular inflammation was present in kidneys of apoE-/-/LDL-/- double knockout mice, predominantly involved are plasma cells and leucocytes. Glomeruli cross-sectional area (9959 +/- 1083 microm2) and number (24.8 +/- 4.5) increased in apoE-/-/LDL-/- double knockout mice compared to controls (3533 +/- 398 microm2; 17.6 +/- 3, respectively), whereas 41% of the total number of glomeruli showed evidence for lipoprotein associated glomerulopathy (LPG). Moreover, immunohistochemistry demonstrated capillary aneurysms of the glomeruli filled with factor 8 containing emboli. CONCLUSION The reduced intra-renal total vascular volume is associated with systemic atherosclerosis and glomeruli alterations in the apoE-/-/LDL-/- double knockout mouse model.

Abstract
OBJECTIVE To investigate the distribution of vasa vasorum (VV) relative to advanced atherosclerotic lesions (calcified, fibrotic or hemorrhaged) along the aortic wall of apoE-/-/LDL-/- mice at the age of 25 and 80 weeks using high-resolution nano-CT. METHODS Aortas from male apoE-/-/LDL-/- mice at the age of 25 weeks (n=4) and 80 weeks (n=7) were infused in situ with contrast agent and harvested for scanning with nano-CT. The spatial distribution of vasa vasorum [number and area/cross-section (mm2)] was compared to aortic luminal cross-sectional area and plaque cross-sectional area in the ascending aorta, aortic arch and descending aorta. Results were complemented with co-localized histology. RESULTS The number and total luminal cross-sectional area of VV showed a significant decrease in the ascending aorta and aortic arch from 25 to 80 weeks but not in the descending aorta. The number and cross-sectional area of VV showed significant local differences depending on whether it was near a fibrotic, and hemorrhaged or calcified plaque in animals at the age of 80 weeks. Area of VV progressively increased along the aorta from least in the ascending aorta<aortic arch<descending aorta in animals at the age of 80 weeks and is inverse in animals aged 25 weeks. CONCLUSION Atherosclerotic lesion type is correlated to the number and cross-sectional area of VV in different aortic segments in apoE-/-/LDL-/- mice. The chronological development of VV along the aorta proceeds distally from the ascending aorta and aortic arch.
