Secretory meningiomas: A benign subgroup causing life-threatening complications

Jan Regelsberger, Christian Hagel, Pedram Emami, Thorsten Ries, Oliver Heese, Manfred Westphal
2009 Neuro-Oncology  
While meningiomas are known as slow-growing extracerebral neoplasms, the subgroup of secretory meningiomas with histologically benign characteristics tend to cause disproportional peritumoral edema, frequently leading to severe medical and neurological complications in postoperative management. Among 1,484 meningiomas that were resected at our institution between 1990 and 2007, 44 (3%) patients were found to have the histological diagnosis of a secretory meningioma. The clinical course,

Meningiomas were located at the convexity (n 5 14), the cranial base (18), and the sphenoid ridge (12). A severe, nearly hemispheric perifocal edema disproportional to tumor size was seen on preoperative MR imaging in 18 (41%) patients. Following surgical resection, the postoperative course was uneventful in 29 patients. In 15 patients, severe peritumoral edema continued or even increased on postoperative CT imaging. Six patients showed midline shift and clinical worsening necessitating respirator-assisted ventilation and intracranial pressure monitoring. An association between the extent of brain edema and number of periodic acid Schiff-positive pseudopsammomas was found (p , 0.02). Further, the size of the edema correlated with the number of immunohistochemically detected cells expressing carcinoembryonic antigen (CEA) and cytokeratin (CK) (p , 0.01). Mean MIB-1 (Ki-67 antigen) proliferation index was 3.0% (range, 0%-17%) and did not correlate with edema or tumor recurrence. Secretory meningiomas are frequently associated with severe peritumoral edema. The extent of edema correlates with immunohistochemically detected expression of CEA and CK. Extended perifocal edema in meningiomas is an unusual finding and should alert the neurosurgeon that surgery may aggravate edema excessively, leading to a life-threatening postoperative situation.

iDataCool: HPC with Hot-Water Cooling and Energy Reuse [chapter]

Nils Meyer, Manfred Ries, Stefan Solbrig, Tilo Wettig
2013 Lecture Notes in Computer Science  
iDataCool is an HPC architecture jointly developed by the University of Regensburg and the IBM Research and Development Lab B\"oblingen. It is based on IBM's iDataPlex platform, whose air-cooling solution was replaced by a custom water-cooling solution that allows for cooling water temperatures of 70C/158F. The system is coupled to an adsorption chiller by InvenSor that operates efficiently at these temperatures. Thus a significant portion of the energy spent on HPC can be recovered in the form

An Extensible Modeling Language for the Representation of Work Processes in the Chemical and Process Industries [chapter]

Ri Hai, Manfred Theißen, Wolfgang Marquardt
2010 Lecture Notes in Computer Science  
Expressive models of the work processes performed in the chemical and process industries provide a basis for diverse applications like work process documentation, analysis, and enactment. In this contribution, we present a generic modeling language for different types of work processes to allow for their integrated representation in the life cycle of a chemical plant. Further, the generic language allows for extensions specific to certain types of work processes. For two important types -design
more » ... and operational processes -such extensions have been elaborated. These extensions enable the adequate representation of the context of a work process that strongly depends on the process type: for instance, the specification of a chemical plant is a product of a design process, whereas the plant takes the role of a resource during an operational process. This contribution also briefly introduces a modeling tool developed by our group for applying the modeling language in industrial practice.

Re-entering obesity prevention: a qualitative-empirical inquiry into the subjective aetiology of extreme obese adolescents

Matthias Braun, Johanna Schell, Wolfgang Siegfried, Manfred J Müller, Jens Ried
2014 BMC Public Health  
While numerous studies highlight the relevance of socio-cultural factors influencing incidence and prevalence of obesity, only a few address how obese people perceive causes and prevention of or intervention for obesity. This study contributes to a more thorough understanding of subjective aetiologies and framing themes for a mainly understudied but promising field. Thus it may serve for the development of effective public health strategies to combat obesity. Methods: Autobiographically based
more » ... -depth interviews were conducted with 20 patients (adolescents and young adults) institutionalised in the obesity rehabilitation centre INSULA in Bischofswiesen (Germany). The data were analysed with Atlas.ti with regard to two main perspectives: (1) How the interviewees perceive 'their' obesity from a subjective point of view and (2) which conclusions they draw from their own 'story' concerning prevention/ intervention strategies. Results: The interviewees did not indicate a clear starting point for their overweight. Nevertheless, certain life-events (e.g. divorce or illness of parents) were identified as catalysing weight gain. As a consequence of coping with distress, body weight rises rapidly and not continuously. Obesity was generally framed as a problem primarily located within the family and not in the wider environment. Corresponding to this, the family was identified as the main and most important addressee of preventive measures. The interviewees highlighted the importance of personal responsibility as a prerequisite for self-determined action against obesity, but denied any link between responsibility and guilt. Conclusions: This study contributes substantially to a broader perspective on the prevention of obesity. First, more attention has to be paid to the interactions of medical aspects and the social dimension of obesity. Second, prevention efforts should be more aware of the relevance of subjective aetiology when it comes to the definition of reasonable and effective governance strategies in tackling obesity. Third, current assumptions concerning the importance of personal responsibility for obesity prevention might underestimate the relevance of self-determined action of the obese.

Activation Mechanisms of the Urokinase-type Plasminogen Activator Promoter by Hepatocyte Growth Factor/Scatter Factor

Sabine Ried, Claudia Jäger, Michael Jeffers, George F. Vande Woude, Henner Graeff, Manfred Schmitt, Ernst Lengyel
1999 Journal of Biological Chemistry  
Hepatocyte growth factor/scatter factor (HGF/SF) is a pleiotropic effector inducing invasion and metastasis of tumor cells that express the Met tyrosine kinase receptor. One of the effectors of HGF/SF is the urokinase-type plasminogen activator, a serine protease that facilitates tumor progression and metastasis by controlling the synthesis of the extracellular matrix degrading plasmin. Stimulation of NIH 3T3 cells that were stably transfected with the human Met receptor (NIH 3T3-Met hum ) with
more » ... HGF/SF induced a trans-activation of the urokinase promoter and urokinase secretion. Induction of the urokinase promoter by HGF/SF via the Met receptor was blocked by co-expression of a dominant-negative Grb2 and Sos1 expression construct. Further, the expression of the catalytically inactive mutants of Ha-Ras, RhoA, c-Raf, and Erk2 or addition of the Mek1-specific inhibitor PD 098059 abrogated the stimulation of the urokinase promoter by HGF/SF. A sequence residing between ؊2109 and ؊1870 base pairs (bp) was critical for stimulation of the urokinase gene by HGF/SF. Mobility shift assays with oligonucleotides spanning an AP-1 site at ؊1880 bp or a combined PEA3/AP-1 site at ؊1967 bp showed binding of nuclear factors from NIH 3T3-Met hum cells. Expression of an expression plasmid that inhibits DNA binding of AP-1 proteins (A-Fos) abrogated inducible and basal activation of the urokinase promoter. Nuclear extract from unstimulated NIH 3T3-Met hum cells contained more JunD and showed a stronger JunD supershift with the AP-1 oligonucleotides, compared with HGF/SF-stimulated cells. Consistent with the levels of JunD expression being functionally important for basal expression of the urokinase promoter, we found that overexpression of wild type JunD inhibited the induction of the urokinase promoter by HGF/SF. These data suggest that the induction of urokinase by HGF/SF is regulated by a Grb2/Sos1/Ha-Ras/c-Raf/RhoA/Mek1/ Erk2/c-Jun-dependent mitogen-activated protein kinase pathway.

2013 BMC Cancer  
Rhabdoid tumors are highly aggressive malignancies affecting infants and very young children. In many instances these tumors are resistant to conventional type chemotherapy necessitating alternative approaches. Methods: Proliferation assays (MTT), apoptosis (propidium iodide/annexin V) and cell cycle analysis (DAPI), RNA expression microarrays and western blots were used to identify synergism of the HDAC (histone deacetylase) inhibitor SAHA with fenretinide, tamoxifen and doxorubicin in
more » ... tumor cell lines. Results: HDAC1 and HDAC2 are overexpressed in primary rhabdoid tumors and rhabdoid tumor cell lines. Targeting HDACs in rhabdoid tumors induces cell cycle arrest and apoptosis. On the other hand HDAC inhibition induces deregulated gene programs (MYCC-, RB program and the stem cell program) in rhabdoid tumors. These programs are in general associated with cell cycle progression. Targeting these activated pro-proliferative genes by combined approaches of HDAC-inhibitors plus fenretinide, which inhibits cyclinD1, exhibit strong synergistic effects on induction of apoptosis. Furthermore, HDAC inhibition sensitizes rhabdoid tumor cell lines to cell death induced by chemotherapy. Conclusion: Our data demonstrate that HDAC inhibitor treatment in combination with fenretinide or conventional chemotherapy is a promising tool for the treatment of chemoresistant rhabdoid tumors.

Purpose We aimed to determine the prevalence of corneal arcus and to identify associated factors in the general population of Germany. Methods The Gutenberg Health Study (GHS) is a population-based cohort study in Germany, which includes an ophthalmological assessment. Refraction, distance-corrected visual acuity, non-contact tonometry and anterior segment imaging were performed for the five-year follow-up examination. Anterior segment photographs were graded for the presence of corneal arcus.
more » ... revalence estimates were computed, and multivariable logistic regression analysis was applied to determine associated factors for corneal arcus including sex, age, spherical equivalent, central corneal thickness, intraocular pressure (IOP), socio-economic status, smoking, BMI, systolic and diastolic arterial blood pressure, HbA1c, HDL-C, LDL-C, triglyceride, and lipid modifying agents. Results A total of 9,850 right and 9,745 left eyes of 9,858 subjects (59.2±10.8 years), 49.0% females were included in this cross-sectional analysis. 21.1% of men (95%-CI: 20.0%– 22.3%) had a corneal arcus in at least one eye, and 16.9% (95%-CI: 15.9%– 18.0%) of women. In multivariable analyses, the presence of corneal arcus was associated with male gender (OR = 0.54 for female, p<0.0001), higher age (OR = 2.54 per decade, p<0.0001), smoking (OR = 1.59, p<0.0001), hyperopia (OR = 1.05 per diopter, p<0.0001), thinner cornea (OR = 0.994 per μm, p<0.0001), higher IOP (OR = 1.02, p = 0.039), higher HDL-C-level (OR = 2.13, p<0.0001), higher LDL-C-level (OR = 1.21, p<0.0001), and intake of lipid modifying agents (OR = 1.26, p = 0.0001). Arcus was not associated with socio-economic status, BMI, arterial blood pressure, and HbA1c. Conclusions Corneal arcus is a frequent alteration of the cornea in Germany and is associated with ocular parameters and systemic parameters of dyslipidemia.

While the international nEDM collaboration at the Paul Scherrer Institut (PSI) took data in 2017 that covered a considerable fraction of the parameter space of claimed potential signals of hypothetical neutron (n) to mirror-neutron (n′) transitions, it could not test all claimed signal regions at various mirror magnetic fields. Therefore, a new study of n−n′ oscillations using stored ultracold neutrons (UCNs) is underway at PSI, considerably expanding the reach in parameter space of mirror

The experiment is distinguished from its predecessors by its very large storage vessel (1.47 m3), enhancing its statistical sensitivity. In a test experiment in 2020 we have demonstrated the capabilities of our apparatus. However, the full analysis of our recent data is still pending. Based on already demonstrated performance, we will reach sensitivity to oscillation times τnn′/cos(β) well above a hundred seconds, with β being the angle between B′ and the applied magnetic field B. The scan of B will allow the finding or the comprehensive exclusion of potential signals reported in the analysis of previous experiments and suggested to be consistent with neutron to mirror-neutron oscillations.
