Abstract
Translation of multipotent mesenchymal stromal cell (MSC)-based therapies is advancing in human and veterinary medicine. One critical issue is the in vitro culture of MSC before clinical use. Using fetal bovine serum (FBS) as supplement to the basal medium is still the gold standard for cultivation of many cell types including equine MSC. Alternatives are being explored, with substantial success using platelet lysate-supplemented media for human MSC. However, progress lags behind in the veterinary field. The aim of this study was to establish a scalable protocol for equine platelet lysate (ePL) production and to test the ePL in equine MSC culture. Whole blood was harvested into blood collection bags from 20 healthy horses. After checking sample materials for pathogen contamination, samples from 19 animals were included. Platelet concentrates were prepared using a buffy coat method. Platelets, platelet-derived growth factor BB, and transforming growth factor β1 concentrations were increased in the concentrates compared with whole blood or serum (p < 0.05), while white blood cells were reduced (p < 0.05). The concentrates were lysed using freeze/thaw cycles, which eliminated the cells while growth factor concentrations were maintained. Donor age negatively correlated with platelet and growth factor concentrations after processing (p < 0.05). Finally, all lysates were pooled and the ePL was evaluated as culture medium supplement in comparison with FBS, using adipose-derived MSC from four unrelated donor horses. MSC proliferated well in 10% FBS as well as in 10% ePL. However, using 5 or 2.5% ePL entailed highly inconsistent proliferation or loss of proliferation, with significant differences in generation times and confluencies (p < 0.05). MSC expressed the surface antigens CD90, CD44, and CD29, but CD73 and CD105 detection was low in all culture media. Adipogenic and osteogenic differentiation led to similar results in MSC from different culture media. The buffy coat method is useful to produce equine platelet concentrate with increased platelet and reduced white blood cell content in large scales. The ePL obtained supports MSC expansion similar as FBS when used at the same concentration (10%). Further investigations into equine MSC functionality in culture with ePL should follow.

Are maternal hemodynamic indices markers of fetal growth restriction in pregnancies with a small-for-gestational-age fetus? ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2020; 55:210-216.

Abstract
OBJECTIVE Pregnancies complicated by fetal growth restriction (FGR) have a worse outcome than those with a small-for-gestational-age (SGA) fetus. There is increasing evidence of a maternal cardiovascular role in the pathophysiology of FGR. We aimed to compare maternal hemodynamic indices between pregnancies complicated by FGR and those delivering a SGA neonate, using a non-invasive device. METHODS This was a prospective study of normotensive pregnancies complicated by FGR (defined as estimated fetal weight (EFW) < 3rd centile or Doppler evidence of impaired placental-fetal blood flow), those with a SGA fetus (defined as EFW < 10th centile) and control pregnancies with an appropriately grown fetus. Assessment of maternal hemodynamics (heart rate (HR), cardiac output (CO), mean arterial pressure (MAP), systemic vascular resistance (SVR) and stroke volume) was performed using a non-invasive device (USCOM-1A®). Uterine artery (UtA) pulsatility index (PI) was measured using transabdominal ultrasound. Hemodynamic variables that are affected by gestational age and maternal characteristics were corrected for using device-specific reference ranges. Comparison between groups was performed using the chi-square test or the Mann-Whitney U-test, as appropriate. RESULTS A total of 102 FGR, 64 SGA and 401 control pregnancies, with a median gestational age of 36 weeks, were included in the analysis. Women with a pregnancy complicated by FGR and those with a SGA fetus were shorter and weighed less than did controls. Compared with controls, the FGR group had significantly lower median maternal HR (80 beats per min (bpm) vs 85 bpm; P = 0.001) and CO multiples of the median (MoM; 0.91 vs 0.98; P = 0.003), and higher median maternal MAP (90 mmHg vs 87 mmHg; P = 0.040), SVR MoM (1.2 vs 1.0; P < 0.001) and UtA-PI MoM (1.1 vs 0.96; P < 0.001), but there was no significant difference in stroke volume MoM (1.0 vs 0.98; P = 0.647). Compared with the SGA group, the FGR group had a significantly lower median HR (80 bpm vs 87 bpm; P = 0.022), and higher median maternal MAP (90 mmHg vs 85 mmHg; P = 0.025), SVR MoM (1.2 vs 1.0; P = 0.002) and UtA-PI MoM (1.1 vs 0.98; P = 0.005), but there was no significant difference in CO MoM (0.91 vs 0.96; P = 0.092) or stroke volume MoM (1.0 vs 1.0; P = 0.806). There were no significant differences in adjusted maternal hemodynamic indices between the SGA group and controls. CONCLUSION Pregnancies complicated by FGR presented with impaired maternal hemodynamic function, as evidenced by lower HR and CO, as well as higher MAP, SVR and UtA resistance. Pregnancies delivering a SGA neonate, without evidence of FGR, had normal maternal hemodynamic function. Maternal hemodynamic indices may therefore be of value in distinguishing FGR from SGA pregnancies. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Correlation between central and uterine hemodynamics in hypertensive disorders of pregnancy. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 54:58-63.

Abstract
OBJECTIVE Pregnancies affected by a hypertensive disorder (HDP) have increased uterine artery pulsatility index (UtA-PI) compared with that in healthy pregnancies. Women with HDP are also known to have lower cardiac output and increased systemic vascular resistance. The aim of this study was to investigate the relationship between central and uterine hemodynamics in HDP and uncomplicated pregnancy. METHODS This was a prospective study of HDP and normotensive control singleton pregnancies presenting at a tertiary referral hospital between January 2012 and December 2017. Paired measurements of maternal hemodynamics, using a non-invasive device (USCOM-1A®), and UtA-PI were performed in the third trimester. HDP pregnancies were divided into preterm (onset < 37 weeks' gestation) and term (onset ≥ 37 weeks). Spearman's rank coefficient was used to assess the correlation between the central and uteroplacental hemodynamics. Regression analysis was performed to assess the association of UtA-PI with independent variables. RESULTS We included 231 women with HDP (152 with preterm and 79 with term HDP) and 378 controls with normotensive pregnancy. Compared with controls, women with preterm HDP had significantly lower cardiac output (median (interquartile range (IQR)), 6.0 (5.1-7.2) vs 6.6 (5.8-7.5) L/min; P < 0.001) and significantly higher systemic vascular resistance (median (IQR), 1394 (1189-1670) vs 1063 (915-1222) dynes × s/cm5 ; P < 0.001) and UtA-PI (median (IQR), 1.0 (0.75-1.4) vs 0.67 (0.58-0.83); P < 0.001). Conversely, in women with term HDP, there were no significant differences in heart rate, cardiac output or UtA-PI compared with controls (all P > 0.05), while systemic vascular resistance was significantly higher (median (IQR), 1315 (1099-1527) vs 1063 (915-1222) dynes × s/cm5 ; P < 0.001). On multiple regression analysis, heart rate, mean arterial pressure and stroke volume were associated significantly with mean UtA-PI (all P < 0.001). CONCLUSIONS Differences observed between HDP and normotensive pregnancies in third-trimester UtA resistance are mirrored in the central maternal hemodynamic parameters. Late pregnancy differences in the uteroplacental circulation in preterm and term HDP are an index of maternal cardiovascular function rather than being related to inadequate spiral artery remodeling and impaired placentation.

Abstract
Phytovigilance consists in supervision of side effects and drug interactions consequential to use of herbal medicinal products, herbal food supplements, herbal cosmetics and/or medicinal plants. It includes thus pharmacovigilance applied to phytotherapy, nutrivigilance and cosmetovigilance but also addictovigilance in case of plants, which lead to drug addiction, and toxicovigilance in case of toxic plants. Becoming necessary owing to (acute or chronic) toxicity risks or to drug interactions risks (of pharmacocinetical or pharmacodynamical kind)--as far as it concerns interactions between several associated plants or between a plant and a chemical or biotechnological allopathic medicine--phytovigilance represents moreover a legal obligation. Pharmacovigilance--in case of herbal medicinal products--is indeed becoming mandatory according to title IX of the European directive 2001/83/EC, whereas nutrivigilance is imposed by the European Food Safety Agency (EFSA).

Abstract
Research-based evidence and practice-based experience are core requirements for the effective implementation of preventive interventions. The knowledge gained in the Prevention Research Funding Initiative of the German Federal Ministry of Education and Research (2004-2013) was therefore amalgamated, reflected and consolidated in the Cooperation for Sustainable Prevention Research (KNP) meta-project. In annual strategy meetings, researchers and practitioners from the field and other experts developed 3 memoranda providing recommendations for the further development of research and practice in the field of prevention and health promotion. Memorandum III is primarily aimed at decision-makers in politics and administration at the federal, state and local level, in civil society and in the workplace. Its recommendations show that structuring efforts are urgently needed to achieve sustainable policy, particularly in the fields of health, education, employment and social affairs. Memorandum III brings together the knowledge extracted and problems identified in research projects. More so than its 2 predecessors, Memorandum III abstracts knowledge from the individual projects and attempts to derive guidance for action and decision-making, as shown by the 7 recommendations that appear to useful for consensus-building in practice and research. Value judgments are inevitable. Prevention and health promotion are an investment in the future: of social health, social capital and social peace. Improvement of the framework conditions is needed to achieve the harmonized awareness and the sustained effectiveness of these structure-building efforts in different policy areas, spheres of life, fields of action, and groups of actors. This includes the implementation of an overall national strategy as well as the expansion of sources of funding, extension of the legal framework, overarching coordination, and the establishment of a National Center of Excellence to develop and safeguard prevention and health promotion. The memorandum is intended to stimulate a discourse resulting in structure-building and stabilizing measures designed to ensure the sustainability of prevention and health promotion.

Abstract
Electron backscattering rates of light elements (atomic number Z = 6, 13, 29) are evaluated for electron energies of E = 20···60 keV. The scattering amplitude in Moliere approximation is expanded as a series. The series elements are calculated in closed form with the aid of substitute functions. By comparison with the first Born approximation this yields correction factors of 1···1,25.

Abstract
The Moliere approximation of the scattering amplitude is, following earlier statements, a high-energy and small-angle approximation. Recent investigations show that there is no intrinsic small-angle restriction, the restriction being due to special derivations. A method is given, to obtain the scattering amplitude in the Moliere approximation without small-angle assumption. This enables to evaluate electron backscattering rates with the aid of the Moliere scattering amplitude.

Copy number variation prevalence in known asthma genes and their impact on asthma susceptibility. Clin Exp Allergy 2013; 43:455-62.

Abstract
BACKGROUND Genetic studies have identified numerous genes reproducibly associated with asthma, yet these studies have focussed almost entirely on single nucleotide polymorphisms (SNPs), and virtually ignored another highly prevalent form of genetic variation: Copy Number Variants (CNVs). OBJECTIVE To survey the prevalence of CNVs in genes previously associated with asthma, and to assess whether CNVs represent the functional asthma-susceptibility variants at these loci. METHODS We genotyped 383 asthmatic trios participating in the Childhood Asthma Management Program (CAMP) using a competitive genomic hybridization (CGH) array designed to interrogate 20 092 CNVs. To ensure comprehensive assessment of all potential asthma candidate genes, we purposely used liberal asthma gene inclusion criteria, resulting in consideration of 270 candidate genes previously implicated in asthma. We performed statistical testing using FBAT-CNV. RESULTS Copy number variation in asthma candidate genes was prevalent, with 21% of tested genes residing near or within one of 69 CNVs. In six instances, the complete candidate gene sequence resides within the CNV boundaries. On average, asthmatic probands carried six asthma-candidate CNVs (range 1-29). However, the vast majority of identified CNVs were of rare frequency (< 5%) and were not statistically associated with asthma. Modest evidence for association with asthma was observed for 2 CNVs near NOS1 and SERPINA3. Linkage disequilibrium analysis suggests that CNV effects are unlikely to explain previously detected SNP associations with asthma. CONCLUSIONS AND CLINICAL RELEVANCE Although a substantial proportion of asthma-susceptibility genes harbour polymorphic CNVs, the majority of these variants do not confer increased asthma risk. The lack of linkage disequilibrium (LD) between CNVs and asthma-associated SNPs suggests that these CNVs are unlikely to represent the functional variant responsible for most known asthma associations.

Effects of simvastatin on pulmonary fibrosis, pulmonary hypertension and exercise capacity in bleomycin-treated rats. Acta Physiol (Oxf) 2013; 208:191-201.

Abstract
AIM Pulmonary fibrosis is often complicated by pulmonary hypertension. Statins reduce fibroblast activity in vitro and pulmonary hypertension in vivo. We investigated whether Simvastatin exerts beneficial effects on pulmonary fibrosis and pulmonary hypertension in Bleomycin-treated rats in vivo. METHODS Rats were randomly assigned to controls, Bleomycin, Bleomycin plus Simvastatin from day 1 to 28 and Bleomycin plus Simvastatin from day 13 to 28. 28 days after Bleomycin instillation, right ventricular systolic pressure (RVSP), right ventricular mass (RV/(LV+S)), right ventricular and circulating brain natriuretic peptide (BNP) levels were determined to assess pulmonary hypertension. Pulmonary hydroxyproline content (HPC), pulmonary connective tissue growth factor (CTGF) transcription and lung compliance (LC) were analysed to characterize pulmonary fibrosis. Exercise capacity was determined by treadmill tests. RESULTS Compared with controls, Bleomycin increased RVSP, RV/(LV+S), BNP levels, HPC and CTGF transcription and decreased LC significantly. Simvastatin administered from day 1 to 28 normalized all these parameters. Simvastatin administered from day 13 to 28 had no effect on HPC and LC, but reduced RV/(LV+S) significantly and induced a strong trend to lower RVSP and BNP levels. Exercise capacity was reduced by Bleomycin. Simvastatin significantly improved exercise intolerance in both treatment groups. CONCLUSIONS Simvastatin prevents the development of pulmonary fibrosis, but fails to attenuate already established pulmonary fibrosis. In contrast, it ameliorates pulmonary hypertension and thereby exercise capacity in the prevention and the treatment group regardless of its effects on pulmonary fibrosis. Whether statins are a treatment option in humans with pulmonary fibrosis needs to be investigated by further study.

Abstract
The memorandum of the research funding of prevention has been devised within the framework of the Prevention Research Funding Programme of the Federal Ministry of Education and Research. It consists not only of the obtained findings of the research-practice co-operation but also of recommendations for the implementation of prospective, innovational, effective, practice-oriented and sustainable research. The respective knowledge has been acquired from quantitative surveys on the experiences of scientists and practice partners within the prevention research funding project as well as from extensive qualitative methods of structured group evaluation. A participatory co-operation between research and practice based on mutual respect, trust and recognition is seen as mandatory for the further development of both prevention and health promotion research. Research and practice partners are required to engage in an ab initio collaboration starting from the conception phase, whereby it is advisable to encourage and fortify the communication between research, practice and funding partners by systematic surveillance in form of a meta-project. In addition, the inclusion of the target population from the outset and on a collaborative basis is considered as beneficial in order to ensure the practical application of the research findings. Furthermore, innovatory research designs which are able to provide a framework for internal flexibility, continuous re-assessment and adjustment are fundamental for the implementation of practice-oriented research. Moreover, a dynamic co-operation between different groups of interest not only depends on sharing responsibility but also on sufficient funding for both research and practice, which is particularly important for the transfer and communication of the attained findings. With regard to the evaluation of both effectiveness and sustainability of interventions, a research funding project is required which makes long-term results possible through the utilization of regulated monitoring and guarantees quality and continuous effectiveness. Furthermore, in order to stimulate progress within the basic theories of prevention and health promotion, it is also essential for a funding project to focus on elementary concepts. Additionally, for the efficient and sustainable development of health within a population it is advisable to apply both self-contained research and the involvement of primary prevention and health promotion to research projects concerning health, social affairs, education, work and environment.

Abstract
We discuss very recent experiments with rodents addressing the idea that long-term memories initially depending on the hippocampus, over a prolonged period, become independent of it. No unambiguous recent evidence exists to substantiate that this occurs. Most experiments find that recent and remote memories are equally affected by hippocampus damage. Nearly all experiments that report spared remote memories suffer from two problems: retrieval could be based upon substantial regions of spared hippocampus and recent memory is tested at intervals that are of the same order of magnitude as cellular consolidation. Accordingly, we point the way beyond systems consolidation theories, both the Standard Model of Consolidation and the Multiple Trace Theory, and propose a simpler multiple storage site hypothesis. On this view, with event reiterations, different memory representations are independently established in multiple networks. Many detailed memories always depend on the hippocampus; the others may be established and maintained independently.

Spectral optical monitoring of nitrate in inland and seawater with miniaturized optical components. WATER RESEARCH 2011; 45:1423-1431.

Abstract
Miniaturized spectral analytical systems become ever increasingly important for in situ monitoring of natural waters' nutrients, such as nitrate, phosphate or ammonium. A miniaturized UV spectral photometer has been developed for online detection using liquid core wave guides (LCW), UV transmitting optical fibers, a low-cost miniature polychromator, and a deuterium light source. The LCWs were manufactured by coating the insides of silica glass capillaries with Teflon(®) AF 1600. Due to this setup our instrument needs only a few microliters of sample for each measurement. Nitrate can be directly detected by UV absorption spectroscopy in a spectral range between 200 and 350 nm. To separate the nitrate absorption from the superposition of other UV absorbing contaminations, a multi component analysis (MCA) software was applied to the measured spectra. With this developed photometer, nitrate levels can be determined online in inland and seawater or, if needed, in situ. It was evaluated twice in the field and the results for the measured amounts of nitrate in reservoir samples and in the North Sea are also presented in this work.
