Abstract
Increasing markets for biopharmaceuticals, including monoclonal antibodies, have triggered a permanent need for bioprocess optimization. Biochemical engineering approaches often include the optimization of basal and feed media to improve productivities of Chinese hamster ovary (CHO) cell cultures. Often, l-tyrosine is added as dipeptide to deal with its poor solubility at neutral pH. Showcasing IgG1 production with CHO cells, we investigated the supplementation of three l-tyrosine (TYR, Y) containing dipeptides: glycyl-l-tyrosine (GY), l-tyrosyl-l-valine (YV), and l-prolyl-l-tyrosine (PY). While GY and YV led to almost no phenotypic and metabolic differences compared to reference samples, PY significantly amplified TYR uptake thus maximizing related catabolic activity. Consequently, ATP formation was roughly four times higher upon PY application than in reference samples.

Abstract
The improvement of cell specific productivities for the formation of therapeutic proteins is an important step towards intensified production processes. Among others, the induction of the desired production phenotype via proper media additives is a feasible solution provided that said compounds adequately trigger metabolic and regulatory programs inside the cells. In this study, S-(5'-adenosyl)- l-methionine (SAM) and 5'-deoxy-5'-(methylthio)adenosine (MTA) were found to stimulate cell specific productivities up to approx. 50% while keeping viable cell densities transiently high and partially arresting the cell cycle in an anti-IL-8-producing CHO-DP12 cell line. Noteworthy, MTA turned out to be the chemical degradation product of the methyl group donor SAM and is consumed by the cells.

Abstract
Purpose We report our experience of using helical tomotherapy (HT) to treat large and irregular shaped loco-regional advanced breast cancer target volumes embracing various organs at risk. Patients and methods We retrospectively analyzed 26 patients treated for very large, irregular shaped breast cancers. Patients were treated either with the intent to achieve local control in a primary setting (n = 14) or in a reirradiation setting (n = 12). The recurrence group was heavily pretreated with systemic therapy. Tumors were characterized by wide infiltration of the skin, encompassing mostly a complete hemithorax. The primary group underwent irradiation of supraclavicular, infraclavicular, axillary and parasternal lymphonodal region. Radiotherapy was combined with chemotherapy (n = 11). We assessed the PTV volume and its craniocaudal extension, the dose to the organs at risk, acute toxicity and survival. Results Median PTV was 2276 cm3 (1476–6837 cm3) with a median cranio-caudal extension of 28 cm (15–52 cm). The median dose to PTV was 40 Gy (32–60Gy). HT could be carried out in all patients without interruption. The acute toxicities were mild to moderate. The median LRFS and OS after radiotherapy was 21 and 57 months for the primary group versus 10 and 11 months for the recurrence group. Median PFS was 18 months (primary group) and 7 months (recurrence group). Conclusions HT is feasible for advanced thorax embracing target volumes with acceptable acute toxicity. Both curative and palliative indications can be considered good indications based on treatment volume and anatomical constellation.

Abstract
AIMS Glucagon-like peptide-1 receptor agonists and inhibitors of dipeptidyl peptidase-4 that increase glucagon-like peptide-1 plasma concentrations are current treatment options for patients with diabetes mellitus. As patients with diabetes are a high-risk population for the development of a severe and diffuse atherosclerosis, we aim to review the potential action of these drugs on cardiovascular disease and to summarize the potential role of present glucagon-like peptide-1-based therapies from a cardiologist's point of view. METHODS Using a PubMed/MEDLINE search without language restriction, studies were identified and evaluated in order to review the effects of glucagon-like peptide-1-based therapy on different stages of the cardiovascular continuum. RESULTS Recent experimental as well as clinical data suggest that dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists--in addition to their metabolic effects--may have beneficial effects on the cardiovascular continuum at multiple stages, including: (1) cardiovascular risk factors; (2) molecular mechanisms involved in atherogenesis; (3) ischaemic heart disease; and (4) heart failure. Furthermore, retrospective analysis suggested decreased cardiovascular events in patients with glucagon-like peptide-1-based therapies. CONCLUSION There are ample data to suggest beneficial effects of glucagon-like peptide-1-based therapies on the cardiovascular continuum and large-scale clinical trials are warranted to determine whether these effects translate into improved cardiovascular endpoints in humans.

Abstract
ErbB2 amplification and overexpression in breast cancer correlates with aggressive disease and poor prognosis. To find novel ErbB2-interacting proteins, we used stable isotope labeling of amino acids in cell culture followed by peptide affinity pull-downs and identified specific binders using relative quantification by mass spectrometry. Copine-III, a member of a Ca(2+)-dependent phospholipid-binding protein family, was identified as binding to phosphorylated Tyr1248 of ErbB2. In breast cancer cells, Copine-III requires Ca(2+) for binding to the plasma membrane, where it interacts with ErbB2 upon receptor stimulation, an interaction that is dependent on receptor activity. Copine-III also binds receptor of activated C kinase 1 and colocalizes with phosphorylated focal adhesion kinase at the leading edge of migrating cells. Importantly, knockdown of Copine-III in T47D breast cancer cells causes a decrease in Src kinase activation and ErbB2-dependent wound healing. Our data suggest that Copine-III is a novel player in the regulation of ErbB2-dependent cancer cell motility. In primary breast tumors, high CPNE3 RNA levels significantly correlate with ERBB2 amplification. Moreover, in an in situ tissue microarray analysis, we detected differential protein expression of Copine-III in normal versus breast, prostate and ovarian tumors, suggesting a more general role for Copine-III in carcinogenesis.

Abstract
INTRODUCTION Levo-Alpha-Acetylmethadol (LAAM) is a synthetic opioid analgesic with mu-agonistic activity and a long duration of action. There are several, almost exclusively US American studies showing the efficacy of LAAM as a maintenance drug which has the advantage that it needs to be administered only three times a week. LAAM is currently not marketed in EU countries due to cardiac complications. We report on the first European multi-center, parallel group, flexible dose, open-label, randomized clinical trial comparing LAAM and methadone in patients with opioid dependence. METHODS Eighty-four opioid addicts in ongoing maintenance treatment with stable methadone doses were treated with methadone under study conditions for 5 weeks (run-in phase), then randomly assigned to a methadone (n=41) or a LAAM (n=43) group. Study duration was 24 weeks after randomization. Objective measures (drug urine screenings, retention rate), subjective measures (symptoms of withdrawal and craving, report of substance use), and safety data were collected weekly. The main outcome criterion was the number of opiate-free urine samples per number of weeks of study participation. RESULTS Non-inferiority was shown for LAAM compared to methadone. Both substances were well tolerated. There were no clinical cardiac complications in either group. DISCUSSION Our study confirmed the results of previous investigations with LAAM as being efficacious and well tolerated in opioid dependence. A discussion to reconsider the availability of LAAM is recommended.

Abstract
Wide-field Coherent Anti-Stokes Raman Scattering (CARS) microscopy is employed to identify saturated and unsaturated fatty acids in micro-emulsions and cells, using the ratio between the strong -C-H CARS signal at 2850 cm(-1) and the weak signal of the =C-H vibration around 3015 cm(-1) for distinction. Quantitative CARS imaging at the =C-H resonance is challenging, since it yields only a low CARS signal, and small differences on the order of 5% in the concentration of polyunsaturated fatty lipids have to be detected. For this purpose we draw advantage of the high signal-to-noise ratio of wide-field CARS microscopy that is achieved by an excitation geometry involving a "sheet-of-light"-type illumination.

Abstract
In this paper, a spatially constrained mixture model for the segmentation of MR brain images is presented. The novelty of this work is an edge-preserving smoothness prior which is imposed on the probabilities of the voxel labels. This prior incorporates a line process, which is modeled as a Bernoulli random variable, in order to preserve edges between tissues. The main difference with other, state of the art methods imposing priors, is that the constraint is imposed on the probabilities of the voxel labels and not onto the labels themselves. Inference of the proposed Bayesian model is obtained using variational methodology and the model parameters are computed in closed form. Numerical experiments are presented where the proposed model is favorably compared to state of the art brain segmentation methods as well as to a spatially varying Gaussian mixture model.

Abstract
We comment on a Letter by Toytman et al. [Opt. Lett.32, 1941 (2007)] in which a novel setup for wide-field imaging in coherent anti-Stokes Raman scattering (CARS) microscopy is demonstrated. There the authors state that our phase-matching implementation of a wide-field CARS system [Appl. Phys. Lett.84, 816 (2004); New J. Phys.8, 36 (2006)] suffers from a strong background from the bulk medium. However, our results show quite the contrary, i.e., that our setup provides a very good signal contrast, due to an almost vanishing background level from the bulk solvent.

Abstract
Standardized tests for speech comprehension have been lacking for the diagnostic investigation of primary school children with problems in hearing and speech development. The informal speech comprehension test for complex syntactic structures ("Sprachverständnistest für komplexe syntaktische Strukturen", SKSS), a shortened and in Swiss German translated modification of the Test for Reception of Grammar of Bishop, was analyzed for its logical validity of content, difficulty indices, selectivity, reliability and standard values in percent. We conducted the SKSS on 64 primary school children (first grade, average age 6.9 years) and 84 primary school children (second grade, average age 8.2 years). Four test sentences were excluded because of their ambiguous nature. The remaining 26 test sentences most often indicated low difficulty. However, there was an obvious difference between the two groups in terms of difficulty as well reliability. Based on our results, the test proved to be useful for screening. It allows both quantitative and qualitative interpretations.

Abstract
This paper presents a method for abdominal sounds analysis based on principal component analysis (PCA). The first steps (wavelet denoising and segmentation, followed by spatial localization) were presented in previous works. After extracting physical features (activity indices) from long time six channel recordings, we propose a reduced representation space obtained by PCA and we present our results in phonoenterogram analysis.

Abstract
This paper proposes a comprehensive evaluation of a monomodal B-spline-based non-rigid registration algorithm allowing topology preservation in 3-D. This article is to be considered as the companion of [Noblet, V., Heinrich, C., Heitz, F., Armspach, J.-P., 2005. 3-D deformable image registration: a topology preservation scheme based on hierarchical deformation models and interval analysis optimization. IEEE Transactions on Image Processing, 14 (5), 553-566] where this algorithm, based on the minimization of an objective function, was introduced and detailed. Overall assessment is based on the estimation of synthetic deformation fields, on average brain construction, on atlas-based segmentation and on landmark mapping. The influence of the model parameters is characterized. Comparison between several objective functions is carried out and impact of their symmetrization is pointed out. An original intensity normalization scheme is also introduced, leading to significant improvements of the registration quality. The comparison benchmark is the popular demons algorithm [Thirion, J.-P., 1998. Image matching as a diffusion process: an analogy with Maxwell's demons. Medical Image Analysis, 2 (3), 243-260], that exhibited best results in a recent comparison between several non-rigid 3-D registration methods [Hellier, P., Barillot, C., Corouge, I., Gibaud, B., Le Goualher, G., Collins, D.L., Evans, A., Malandain, G., Ayache, N., Christensen, G.E., Johnson, H.J., 2003. Retrospective evaluation of intersubject brain registration. IEEE Transactions on Medical Imaging, 22 (9), 1120-1130]. The topology preserving B-spline-based method proved to outperform the commonly available ITK implementation of the demons algorithms on many points.
