Untersuchungen zur Herstellung von nanoskaligem Bariumsulfat
Authors: Petrova A. , Hintz W. , Tomas J. 
Published: February 2008

AbstractDie Fällung ist ein vielversprechender Prozess zur Nanopartikelherstellung, da er schnell, kostengünstig und verfahrenstechnisch einfach zu gestalten ist. Im Rahmen der vorliegenden Untersuchungen wurden Bariumsulfatpartikel in diskontinuierlichen Fällungsversuchen in einem Rührkesselreaktor hergestellt. Es wurden Partikelgrößen unter 100 nm erreicht. Die Partikelgrößenverteilungen hängen stark von der Vermischung und dem stöchiometrischen Verhältnis der Reaktanden sowie von der Stabilisierung der Partikeloberfläche ab.
Phosphorsäuredotierte Protonenleiter auf Basis von aminierten Membranen aus ETFE‐graft‐poly‐(glycidylmethacrylat)‐Derivaten
Authors: Schmidt C. , Schmidt‐Naake G. 
Published: February 2008

AbstractPolymere Protonenleiter der so genannten zweiten Generation sollen eine Betriebstemperatur von deutlich über 100 °C bei keiner oder nur geringer Befeuchtung der Betriebsgase ermöglichen und so die Effizienz von Polymerelektrolyt‐Brennstoffzellen (PEM‐FC) erheblich steigern. Komposite aus basischen Polymeren und Säuren gelten seit einiger Zeit als aussichtsreiche Ansätze für Brennstoffzellensysteme, die bei verringerter Feuchte und erhöhten Temperaturen operieren. Basierend auf diesem Konzept werden in dieser Arbeit basische Polymermembranen vorgestellt, die durch strahlungsinduzierte Pfropfpolymerisation von Glycidylmethacrylat mit Butylacrylat und Acrylnitril auf Filmen aus Poly(tetrafluorethylen‐alt‐ethylen) (ETFE) und anschließender Umsetzung mit Alkylaminen erzeugt werden. Durch anschließende Dotierung mit Phosphorsäure – bis zu 86 Gew.‐% – können diese Matrices in Protonenleiter überführt werden, die auch bei 125 °C und ohne Befeuchtung hohe Leitfähigkeiten bis zu 60 mS/cm aufweisen. Die Säuredotierung der erhaltenen basischen Polymermatrices sowie die Charakterisierung des Polymer/Säure‐Komposits hinsichtlich thermischer und mechanischer Stabilität sind ebenfalls Teil dieser Arbeit.

AbstractReactions of the pyridyl side chain functionalized indenes 3‐R‐C9H7 [R = (C5H4N)CH2CMe2 (1), (MeC5H3N)CH2CMe2 (2), (C5H4N)CH2 (6)] with Ru3(CO)12 in refluxing xylene gave the facial coordinated indenyl cluster [μ3‐η5:η2:η2‐(C5H3N)CH2Me2C(C9H6)]Ru4(μ3‐CO)(CO)7 (8), the syn‐η5:η6‐coordinated indenyl cluster [μ‐η5:η6‐(MeC5H3N)CH2CMe2(C9H6)Ru2(CO)3]2 (10), and the η1:η2‐coordinated indenyl complex[η2‐(C5H3N)CH2(C9H7)][η1:η2‐(C5H4N)CH2(C9H6)]Ru2(CO)4(18), respectively, in addition to the normal diruthenium complexes [(η5‐RC9H6)Ru(CO)]2(μ‐CO)2 [R = (C5H4N)CH2CMe2 (7), (MeC5H3N)CH2CMe2 (9), (C5H4N)CH2 (17)]. When the pyridyl side chains were replaced by other bulky groups [R = tBu (3), PhCH2Me2C (4), (C9H6N)CH2Me2C (5)], the similar syn‐η5:η6‐coordinated indenyl clusters 12, 14, and 16 were also obtained. When 1 or 2 were treated with Ru3(CO)12 in refluxing heptane, the ionic clusters {[(C5H4N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (19), [(C5H4N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (20), and complex 8 or ionic clusters {[(MeC5H3N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (21) and [(MeC5H3N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (22) were obtained. Similar treatment of 5 or 6 with Ru3(CO)12 in refluxing heptane gave the ionic clusters [(C9H6N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (23) or {[η3‐(C5H4N)CH(C9H7)][η2‐(C5H4N)CH2(C9H7)]Ru(CO)}+[HRu6(CO)18]– (24), respectively, in addition to complex 18 in the latter case. The molecular structures of 8, 9, 10, 14, 17, 18, 21, 22, and 24 were determined by X‐ray diffraction analysis.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Nonresectable carotid body tumor: Hybrid surgical procedure to achieve complete and safe resection
Authors: Hurtado‐Lopez Luis Mauricio , Fink‐Josephi Gustavo , Ramos‐Méndez Luis , Dena‐Espinoza Ernesto 
Published: February 2008

AbstractBackgroundCarotid body tumors of Shamblin class III without free internal carotid, between the tumor and skull base, are considered nonresectable. The objective of this work is to describe a surgical technique that combines traditional and endovascular strategies to achieve a safe surgical resection of the carotid body tumor of this class.Methods and ResultsA female patient with a nonresectable carotid body tumor underwent placement of an endoprosthesis going from the common carotid artery to the internal carotid beyond the skull base (to secure cerebral circulation) excluding the external carotid artery. Forty‐five days later, the tumor was resected without vascular or cranial nerves injury, and bleeding amounted to 50 cm3. At 6 months, the patient is tumor free and asymptomatic.ConclusionThis is the first known reported case that has been successfully resolved by combining endovascular and traditional strategies. The endoprosthesis maintained cerebral circulation, which otherwisewould have been impossible; besides, the vascular supply from the external carotid artery was excluded leading to a decrease in tumor size and a recovery of the subadventitial dissection plane, allowing for a successful and safe tumor resection. © 2008 Wiley Periodicals, Inc.

Kinetic simulation model of protein secretion and accumulation in the cell microcapsules
Authors: Wikström J. , Syväjärvi H. , Urtti A. , Yliperttula M. 
Published: February 2008

AbstractBackgroundIn cell therapy, microencapsulated cells secrete therapeutic protein, which is further released from the microcapsules. In principle, some secreted, but unreleased, protein may accumulate in the microcapsules. The kinetic simulation model was built to simulate the potential accumulation of the protein in the microcapsules.MethodsThe alginate microcapsules were cross‐linked with divalent cations to encapsulate either flourescein isothiocyanate (FITC)‐dextrans (molecular weights = 4.3, 10.5, 43 kDa) or retinal pigment epithelial cells (ARPE‐19). The cells were genetically engineered to produce secreted alkaline phosphatase (SEAP). SEAP production from the cells was quantified with and without microcapsulation and, finally, the cells were killed with toxin to quantify the secreted but yet unreleased SEAP from the microcapsules. The empirical three‐compartment kinetic model was constructed based on the release of FITC‐dextrans of different molecular weights from the alginate microcapsules with different pore sizes. Protein secretion from the cells into the microcapsules was added to the model. The impact of the microcapsule wall permeability on the steady‐state amounts of secreted protein in the microcapsules and in the hypothetical target compartment in the body was simulated. The simulations were compared to the experimental data from the microencapsulated SEAP secreting ARPE‐19 cells.ResultsThe model and the data show that substantial amounts (10–15 daily doses) of protein may accumulate in the microcapsules with poor wall permeability. At high permeability, the accumulation was insignificant. The pharmacokinetic simulations show that even a 1.5‐fold increase in the wall permeability may result in a substantial peak in the drug amount in the target compartment, especially if the elimination rate of the protein is high.ConclusionsThe kinetic simulation model for protein secretion from microcapsulated cells is a useful tool for the early kinetic prediction and risk assessment of cell therapy.

Transient resonance Raman spectroscopy and DFT calculations of metal‐to‐ligand charge transfer states of Cu(I) complexes of substituted 1,10‐phenanthroline ligands and their perdeuterated isotopomers
Authors: Howell Sarah L. , Gordon Keith C. 
Published: February 2008

AbstractCu(I) complexes of the type [Cu(L)(PPh3)2]+, where L is the bidentate ligand 4,7‐diphenyl‐1, 10‐phenanthroline (dip) and 3,4,7,8‐tetramethyl‐1,10‐phenanthroline (tem) and their perdeuterated analogues, have been synthesised and the transient resonance Raman spectra of these complexes have been measured. The spectra show two sets of bands, one due to the PPh3 ligands and the other due to L.− created through the metal‐to‐ligand charge transfer transition. Density functional theory calculations have been used to model ligands and complexes in the ground state and good agreement has been found between calculated and measured bands with a mean absolute deviation of 8–10 cm−1 for the ligands and 5 cm−1 for the complexes. Shifts in the bands due to deuteration have also been well predicted, with the shifts for most modes predicted to within 10 cm−1. The structure and spectra of the excited states have been modelled using two approaches. The reduced state [Cu(L.−)(PH3)2] was used for both complexes to predict the changes in the structure of the polypyridyl ligand and for [Cu(dip)(PPh3)2]+ the triplet state was also optimised. Both approaches show that similar structural changes in the ligand are predicted. In the case of [Cu(dip)(PPh3)2]+* and [Cu(dip.−)(PPh3)2], the calculated states are 3A2 and 2A2, respectively, consistent with experiment. Calculations on [Cu(tem)(PPh3)2]+* give a 3B1 state. This is not consistent with experimental results. For [Cu(tem.−)(PPh3)2] both the 2B1 and 2A2 states may be calculated and the experimental spectrum of [Cu(tem)(PPh3)2]+* is closer to that of the 2A2 [Cu(tem.−)(PPh3)2] species. Calculated wavenumbers are compared to measured transient resonance Raman L.− bands and found to have a mean absolute deviation of 8 cm−1 for the triplet state of [Cu(dip)(PPh3)2]+ and 16 cm−1 for the reduced state of [Cu(tem)(PPh3)2]+.

Published: February 2008

AbstractBackground and ObjectiveRadiofrequency represents the most recent skin‐rejuvenation treatment. The aim of this study was to study the changes in tissues and cells, as well as in the thickness and structure of the skin of guinea pigs following several sessions of radiofrequency.Materials and MethodsSix sessions (1 session/week) of radiofrequency (Thermafine Lift device, Grupo Soliláser, S.L., Girona, Spain) were applied to the skin of guinea pigs. Biopsies were taken following each session and 2 months following the last application. The resultant samples were included in paraffin via the usual method, sectioned at 5 µm and stained with Haematoxylin‐Eosin, Alcian blue, Toluidine blue, van Gieson's and Verhoeff's stains. These techniques were used in order to observe possible changes in the thickness and structures of the skin: mucopolysaccharides and collagen and elastic fibres.ResultsThe most relevant changes were found in the papillary dermis which underwent an expansion due to oedema and vascular congestion (first half of the experiment), followed by an increase in cellularity and the accumulation of intercellular substance. An increase in collagen, elastic fibres and mucopolysaccharides was observed.ConclusionThe Thermafine Lift device caused no significant macroscopic or microscopic alterations in the skin of guinea pigs, yet increased both the thickness, as well as the mucopolysaccharide, collagen and elastic‐fibre content.

Published: March 2008

AbstractVoxel‐based morphometry (VBM) enables an unbiased in‐vivo whole‐brain quantitative analysis of differences in gray matter (GM), white matter (WM) and cerebro‐spinal fluid (CSF) volumes. We assessed with VBM 20 spinocerebellar ataxia Type 2 (SCA2) patients with mild or moderate cerebellar deficit and 20 age and sex‐matched healthy controls. SCA2 patients showed a significant (P < 0.05 corrected for multiple comparison) symmetric loss of GM in the cerebellar vermis and hemispheres sparing lobules I,II, Crus II,VII, and X, and of the WM in the peridentate region, middle cerebellar peduncles, dorsal pons, and cerebral peduncles. The CSF volume was increased in the posterior cranial fossa. No GM, WM or CSF volume changes were observed in the supratentorial compartment. A mild (P < 0.05, >0.01) correlation was observed between the GM and WM loss and severity of the neurological deficit. In SCA2 patients with mild to moderate cerebellar deficit, GM and WM volume loss and CSF volume increase are confined to the posterior cranial fossa. © 2008 Movement Disorder Society
Late onset Wilson's disease: Therapeutic implications
Authors: Członkowska Anna , Rodo Maria , Gromadzka Grażyna 
Published: March 2008

AbstractThe clinical symptoms of Wilson's disease (WD) usually develop between 3 and 40 years of age and include signs of liver and/or neurologic and psychiatric disease. We report on an 84‐year‐old woman with WD. Despite the absence of treatment, the only symptom she presented with, until the age of 74 years, was Kayser‐Fleisher rings. At the age of 74, she developed slightly abnormal liver function. This case raises the following issues: (a) Should WD be considered in all patients of all ages who manifest signs related to the disease? (b) Are ATP7B mutations fully penetrant? (c) Should all patients diagnosed presymptomatically receive anticopper therapy? © 2008 Movement Disorder Society

Published: February 2008

AbstractA stimulated‐echo‐based technique was developed to measure the regional apparent diffusion coefficient (ADC) of hyperpolarized 3He during a single breathhold for diffusion times of 25 ms or greater. Compared to previous methods, a substantially shorter minimum diffusion time was achieved by decoupling diffusion sensitization from image acquisition. A hyperpolarized‐gas phantom was used to validate the method, which was then tested in four healthy subjects in whom regional ADC maps were acquired with diffusion times of 50, 200, and 1500 ms and a tag wavelength of 5 or 10 mm. ADC values from healthy subjects were in good agreement with reported literature values and decreased with increasing diffusion time. Mean ADC values were ≈0.07, 0.03, and 0.015 cm2/s for diffusion times of 50, 200, and 1500 ms, respectively. ADC maps were generally homogeneous, with similar mean values when measured with the same parameters in different subjects. Magn Reson Med 59:673–678, 2008. © 2008 Wiley‐Liss, Inc.
Quality of Care and Racial Health Disparities: A Strategic Overview
Authors: Chassin Mark R. , Anderson Rebecca M. 
Published: February 2008

AbstractSubstantial racial and ethnic disparities in health and health care exist in the United States. The Department of Health Policy at the Mount Sinai School of Medicine has developed a strategy for reducing those disparities that builds upon its quality improvement experience. This article discusses the utility of applying quality improvement principles to the development of interventions to eliminate underuse of effective treatments and reduce the disparities that may arise from this quality problem. We present a conceptual model of racial disparities in health and our underuse hypothesis. Parallels between our disparities research strategy and six sigma quality improvement methods are described. Finally, the article provides an example of how we have been able to successfully implement proven‐effective health improvement programs in the Harlem community even after grant funding has ended.

Nonprofit versus corporate governance: An economic approach
Authors: Speckbacher Gerhard 
Published: March 2008

AbstractThis article proposes a new theoretical concept of nonprofit governance using transaction cost economics and the economic theory of contracts. After a short review of economic approaches to corporate governance, I clarify the specific nature of the governance problem in nonprofit organizations. Based on this analysis, I derive criteria for selecting an organization's relevant stakeholders. If stakeholders provide valuable specific resources without the protection of a comprehensive contract that details exactly how the organization is to use these resources, then such stakeholders seek decision and control rights in order to direct the use of the resources they have provided. I argue that the core problem of governance is how to enhance valuable specific contributions of the relevant stakeholders while keeping the costs of bargaining between stakeholders and the costs of collective decision making low. The theory developed is then applied in a discussion of practically relevant governance mechanisms, and the concept of governance is used to contribute to the discussion on the strengths and weaknesses of the nonprofit character of organizations from a governance perspective.
Leadership development inside‐out in Africa
Authors: James Rick 
Published: March 2008

AbstractLeadership development is a high priority for African nonprofit organizations, but we know very little about what causes leaders in Africa change their behavior and how. Most leadership development programs use imported Western models that at best pay only lip‐service to the very different culture and context in Africa. This article outlines the research findings of a three‐country study conducted in Malawi, Uganda, and Kenya. This study found that changes in leadership style, although individual and complex, followed an underlying pattern. External events catalyzed an inside‐out change process. Effective leadership development requires in‐depth understanding and application of local contextual and cultural issues. Ultimately, however, the process of leadership development is tied to deeper, universal principles of human behavior.

Memento of the post‐mortem
Authors: van Speybroeck D , van Krieken J , van Daal W , Ruiter D 
Published: February 2008

AbstractWhen the Department of Pathology of the Radboud University Nijmegen Medical Centre in The Netherlands moved from its old to its new premises, the demolition of the marble post‐mortem tables was impending, taking with it the Department's (physical) memory. To keep the importance of this memory and of the post‐mortem itself on everyone's minds in the new building, the artist Piet Hein Eek was invited to incorporate these post‐mortem tables into a work of art. This became a triptych: the three post‐mortem tables were stood upright against the wall behind a mounted double sheet of glass, containing screen prints of enlarged microscopic images. The two emblems of pathology–post‐mortem tables and double glass slides containing specimens–were thus united into a fascinating work of art: a true memento of the post‐mortem, re‐embedded in the contemporary world by its design.
