Abstract
In most vertebrates, including zebrafish, the hypothalamic serotonergic cerebrospinal fluid-contacting (CSF-c) cells constitute a prominent population. In contrast to the hindbrain serotonergic neurons, little is known about the development and function of these cells. Here, we identify fibroblast growth factor (Fgf)3 as the main Fgf ligand controlling the ontogeny of serotonergic CSF-c cells. We show that fgf3 positively regulates the number of serotonergic CSF-c cells, as well as a subset of dopaminergic and neuroendocrine cells in the posterior hypothalamus via control of proliferation and cell survival. Further, expression of the ETS-domain transcription factor etv5b is downregulated after fgf3 impairment. Previous findings identified etv5b as critical for the proliferation of serotonergic progenitors in the hypothalamus, and therefore we now suggest that Fgf3 acts via etv5b during early development to ultimately control the number of mature serotonergic CSF-c cells. Moreover, our analysis of the developing hypothalamic transcriptome shows that the expression of fgf3 is upregulated upon fgf3 loss-of-function, suggesting activation of a self-compensatory mechanism. Together, these results highlight Fgf3 in a novel context as part of a signalling pathway of critical importance for hypothalamic development. Summary: This study highlights Fgf3 in a novel context where it is part of a signalling pathway of critical importance for development of hypothalamic monoaminergic cells in zebrafish.

Abstract
Peripheral nerve injuries due to sports are relatively rare but the exact incidence is not known due to a lack of epidemiological studies. Particular sports activities tend to cause certain peripheral nerve injuries including direct acute compression or stretching, repetitive compression and stretching over time, or another mechanism such as ischemia or laceration. These nerve lesions may be severe and delay or preclude the athlete's return to sports, especially in cases with delayed diagnosis. Repetitive and vigorous use or overuse makes the athlete vulnerable to disorders of the peripheral nerves, and sports equipment may cause compression of the nerves. Depending on etiology, the treatment is primarily conservative and includes physiotherapy, modification of movements and sports equipment, shoe inserts, splinting, antiphlogistic drugs, sometimes local administration of glucocorticoids or, lately, the use of extracorporeal shock waves. Most often, cessation of the offending physical activity is necessary. Surgery is only indicated in the rare cases of direct traumatic nerve injury or when symptoms are refractory to conservative therapy. Prognosis mainly depends on the etiology and the available options of modifying measures.This article is based on the publications "Reuter I, Mehnert S. Engpasssyndrome peripherer Nerven bei Sportlern". Akt Neurol 2012;39:292-308 and Sportverl Sportschad 2013;27:130-146.

Abstract
First line pain relief medication during pregnancy relies nearly entirely on the over-the-counter analgesic acetaminophen, which is generally considered safe to use during gestation. However, recent epidemiological studies suggest a risk of developing attention-deficit/hyperactivity disorder (ADHD)-like symptoms in children if mothers use acetaminophen during pregnancy. Currently, there are no experimental proofs that prenatal acetaminophen exposure causes developmental brain alterations of progeny. Exposure to high acetaminophen concentrations causes liver toxicity, which is well investigated in different model organisms. However, sub-liver-toxic concentrations have not been experimentally investigated with respect to ADHD endophenotypes such as hyperactivity. We used zebrafish to investigate the potential impact of acetaminophen exposure on locomotor activity levels, and compared it to the established zebrafish Latrophilin 3 (Lphn3) ADHD-model. We determined the sub-liver-toxic concentration of acetaminophen in zebrafish larvae and treated wild-type and lphn3.1 knockdown larvae with increasing concentrations of acetaminophen. We were able to confirm that lphn3.1 knockdown alone causes hyperactivity, strengthening the implication of Lphn3 dysfunction as an ADHD risk factor. Neither acute nor chronic exposure to acetaminophen at sub-liver-toxic concentrations in wild-type or lphn3.1 knock-downs increases locomotor activity levels. Together our findings show that embryonic to larval exposure to acetaminophen does not cause hyperactivity in zebrafish larvae. Furthermore, there are no additive and/or synergistic effects of acetaminophen exposure in a susceptible background induced by knock-down of lphn3.1. Our experimental study suggests that there is, at least in zebrafish larvae, no direct link between embryonic acetaminophen exposure and hyperactivity. Further work is necessary to clarify this issue in humans.

Abstract
Physical inactivity is a major but modifiable risk factor for morbidity and mortality. Regular physical activity has preventive and therapeutic effects on numerous diseases including neurological disorders. Therefore, it is desirable that physicians motivate their patients to increase their physical and sports activities and that they help them to overcome barriers to exercising. The present study is a survey of neurologists who are members of the German Neurological Society with their own practices; they were asked whether they advised their patients on the benefits of physical activity. Details on physician counseling on physical activity were obtained, such as the frequency of counseling, the neurological disorders considered by the practitioners to be worth the effort of counseling, and the barriers to exercise on the part of patients. More than 80 % of the participants who responded to the survey stated that they frequently provide their patients with advice on the preventive and therapeutic aspects of physical activity. Almost all of them recommended endurance sports; this was followed by Far Eastern types of sport such as tai chi or yoga (70 % of all physicians who advice sports activities). The frequency of counseling about physical activity significantly correlated to the physician's own sports activity. Frequency of counseling was reduced if the physician assessed the patients to be incapable of adopting and maintaining a lifestyle of habitual physical activity. Lack of time as well as an insufficient reimbursement of the counseling, however, did not significantly influence the frequency of counseling. The physician's own sports activity matched that of individuals with similar social status. Thus, a selection bias does not seem to be of importance regarding the results of the survey. However, since only 169 of the 784 invited neurologists (21.6 %) responded to the questionnaire, the representativeness of the survey may be limited. Counseling about physical activity seems to be an essential part of consultations in neurological practices.

Abstract
Sports-related injuries most commonly involve the musculoskeletal system. However, physicians are less familiar with damage to the peripheral nerves attributable to particular sports activities. Nerve entrapment syndromes associated with physical activity may affect all nerves for which entrapment syndromes are known. Peripheral nerve lesions are serious and may delay or preclude the athletes' return to sports, especially in cases with a delayed diagnosis. The aim of the paper is to give an overview of chronic sports-related nerve lesions. Acute nerve injuries are not the focus of this review. A literature search regarding sports-related nerve lesions was conducted. Due to the lack of prospective epidemiological studies, case reports were included (evidence level 4). Nerve entrapment syndromes specific for particular sports activities are described including clinical presentation, diagnostic work-up and treatment. Repetitive and vigorous use or overuse makes the athlete vulnerable to disorders of the peripheral nerves, additionally sports equipment may cause compression of the nerves. The treatment is primarily conservative and includes modification of movements and sports equipment, shoe inserts, splinting, antiphlogistic drugs and local administration of glucocorticoids. Most often cessation of the offending physical activity is necessary. When symptoms are refractory to conservative therapy a referral to surgery is indicated. The outcome of surgical treatment regarding the return of the athlete to competitive sports is not sufficiently investigated in many nerve entrapment -syndromes. This article was primarily published in "Akt Neurol 2012; 6: 292-308".

Abstract
Mild cognitive impairment, especially executive dysfunction might occur early in the course of Parkinson's disease. Cognitive training is thought to improve cognitive performance. However, transfer of improvements achieved in paper and pencil tests into daily life has been difficult. The aim of the current study was to investigate whether a multimodal cognitive rehabilitation programme including physical exercises might be more successful than cognitive training programmes without motor training. 240 PD-patients were included in the study and randomly allocated to three treatment arms, group A cognitive training, group B cognitive training and transfer training and group C cognitive training, transfer training and psychomotor and endurance training. The primary outcome measure was the ADAS-Cog. The secondary outcome measure was the SCOPA-Cog. Training was conducted for 4 weeks on a rehabilitation unit, followed by 6 months training at home. Caregivers received an education programme. The combination of cognitive training using paper and pencil and the computer, transfer training and physical training seems to have the greatest effect on cognitive function. Thus, patients of group C showed the greatest improvement on the ADAS-Cog and SCOPA-COG and were more likely to continue with the training programme after the study.

Abstract
BACKGROUND AND PURPOSE In PD, tissue damage occurs in specific cortical and subcortical regions. Conventional MR images have only limited capacity to depict these structural changes. The purpose of the current study was to investigate whether voxel-based MT imaging could indicate structural abnormalities beyond atrophy measurable with T1-weighted MR imaging. MATERIALS AND METHODS Thirty-six patients with PD without dementia (9 in H&Y stage 1, thirteen in H&Y 2, eleven in H&Y 3, three in H&Y 4) and 23 age-matched control subjects were studied with T1-weighted MR imaging and MT imaging. Voxel-based analyses of T1-weighted MR imaging was performed to investigate brain atrophy, while MT imaging was used to study abnormalities within existing tissue. Modulated GM and WM probability maps, sensitive to volume, and nonmodulated maps, indicative of tissue density, were obtained from T1-weighted MR imaging. Effects seen on MTR images, but absent on density maps, were attributed to damage of existing tissue. RESULTS Contrary to T1-weighted MR imaging, MT imaging was sensitive to the progression of brain pathology of the neocortex and paraventricular WM. MTR images and T1-based volume images, but not density images, showed a progression of disease in the olfactory cortex, indicating the occurrence of atrophy as well as damage to existing tissue in this region. MTR images revealed bilateral damage to the SN, while T1-weighted MR imaging only showed left-sided abnormalities. CONCLUSIONS The findings suggest that voxel-based MT imaging permits a whole-brain unbiased investigation of CNS structural integrity in PD and may be a valuable tool for identifying structural damage occurring without or before measurable atrophy.

Abstract
Spasticity is one of the major causes of functional impairment in adults with lesions of the central nervous system. For instance, approximately 30% of post-stroke patients suffer from different degrees of spasticity with possible consecutive impairments. Numerous studies or meta-analyses showed that local injections of botulinum toxin in spastic muscles lead to dose-dependent reduction in muscle tone and improvement of passive movements (e. g. facilitated care), especially following repeated injections.However, country-specific regulations and patient-remote administration in German health care often do not allow adequate provision of this therapy. Thus, the present consensus statement based on the EBM analyses of the published international literature tries to highlight recent advances and the standard in the field of local spasticity treatment, aiming to facilitate communication between the decision makers and German reimbursement institutions in health care. Prior to initiation of BoNT-A injections, patient-oriented goals should be identified in a multiprofessional context to assure realistic goals for this specific treatment and patient expectations. In Germany for the treatment of focal spasticity following stroke three products have been approved: Botox® (Pharm Allergan, Ettlingen), Dysport® (Ipsen Pharma, Ettlingen) and Xeomin® (Merz Pharma, Frankfurt/Main). For all preparations safety has been repeatedly shown. Functional improvements have also been illustrated for selected patients concerning hand/arm function and gait. The dose per muscle and the selection of muscles to be injected have to be individualized according to the patient's symptoms and should be accompanied by modern neurorehabilitative therapies such as redression or repetitive activation of the injected and antagonistic muscles.

Abstract
Symptoms of Parkinson's disease (PD) progress despite optimized medical treatment. The present study investigated the effects of a flexibility and relaxation programme, walking, and Nordic walking (NW) on walking speed, stride length, stride length variability, Parkinson-specific disability (UPDRS), and health-related quality of life (PDQ 39). 90 PD patients were randomly allocated to the 3 treatment groups. Patients participated in a 6-month study with 3 exercise sessions per week, each lasting 70 min. Assessment after completion of the training showed that pain was reduced in all groups, and balance and health-related quality of life were improved. Furthermore, walking, and Nordic walking improved stride length, gait variability, maximal walking speed, exercise capacity at submaximal level, and PD disease-specific disability on the UPDRS in addition. Nordic walking was superior to the flexibility and relaxation programme and walking in improving postural stability, stride length, gait pattern and gait variability. No significant injuries occurred during the training. All patients of the Nordic walking group continued Nordic walking after completing the study.

Abstract
Two patients with moderate Huntington's disease (HD) received bilateral fetal striatal allografts. One patient demonstrated, for the first time, increased striatal D2 receptor binding, evident with 11C-raclopride positron emission tomography, and prolonged clinical improvement over 5 years, suggesting long term survival and efficacy of the graft. The other patient did not improve clinically or radiologically. Our results indicate that striatal transplantation in HD may be beneficial but further studies are needed to confirm this.

Abstract
INTRODUCTION Diffusion-weighted (DW) MR imaging enables early identification of ischemic lesions in stroke. Stroke subtype may be related to different lesion patterns. The aim of this study was to analyze the subtype of ischemic lesions as determined by the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria by using DW MR imaging. METHODS AND RESULTS In this study, 510 consecutive patients with ischemic stroke (95%) and transient ischemic attack (5%) aged 65 +/- 12 years were investigated by use of DW MR imaging within 48 hours of the clinical onset of symptoms. Lesions on DW imaging were classified as single, scattered, or multiple lesions in one vascular territory and multiple in more than one vascular territory. We found a significant overall association of DW imaging lesion patterns and classification with stroke subtype by using the TOAST criteria (P < .001). Single corticosubcortical lesions (P < .01) and multiple bilateral lesions in the anterior (AC) and posterior circulation (P < .001) on DW imaging were significantly associated with a cardiac embolic source. Multiple unilateral lesions in the AC were significantly associated with large-artery arteriosclerosis. Because of the 15-mm criterion for small-artery occlusion, cryptogenic stroke was significantly associated with subcortical lesions >/=15 mm. CONCLUSION We found a strong relationship between stroke subtype and DW imaging lesion pattern. The finding of multiple bilateral lesions was significantly associated with a cardiac embolic source, which may be caused by a specific thrombus texture with a tendency for embolus dissemination.

Abstract
The TRANSFAC database on transcription factors, their binding sites, nucleotide distribution matrices and regulated genes as well as the complementing database TRANSCompel on composite elements have been further enhanced on various levels. A new web interface with different search options and integrated versions of Match and Patch provides increased functionality for TRANSFAC. The list of databases which are linked to the common GENE table of TRANSFAC and TRANSCompel has been extended by: Ensembl, UniGene, EntrezGene, HumanPSD and TRANSPRO. Standard gene names from HGNC, MGI and RGD, are included for human, mouse and rat genes, respectively. With the help of InterProScan, Pfam, SMART and PROSITE domains are assigned automatically to the protein sequences of the transcription factors. TRANSCompel contains now, in addition to the COMPEL table, a separate table for detailed information on the experimental EVIDENCE on which the composite elements are based. Finally, for TRANSFAC, in respect of data growth, in particular the gain of Drosophila transcription factor binding sites (by courtesy of the Drosophila DNase I footprint database) and of Arabidopsis factors (by courtesy of DATF, Database of Arabidopsis Transcription Factors) has to be stressed. The here described public releases, TRANSFAC 7.0 and TRANSCompel 7.0, are accessible under http://www.gene-regulation.com/pub/databases.html.

Abstract
Running is rarely associated with acute injuries (muscle injuries, ankle sprain, ruptures of the Achilles tendon). More than 80% of the complaints are due to overuse injuries, mainly concerning knee, foot and Achilles tendon. Risk factors are high-performance sports, high training quantity, rapid increase of training intensity, previous injuries, and skeletal axis malalignment. Running is not suitable for severely overweight people and those with significant skeletal malalignment, dysplastic hips, spondylolisthesis, or cartilage damage.

Abstract
Match is a weight matrix-based tool for searching putative transcription factor binding sites in DNA sequences. Match is closely interconnected and distributed together with the TRANSFAC database. In particular, Match uses the matrix library collected in TRANSFAC and therefore provides the possibility to search for a great variety of different transcription factor binding sites. Several sets of optimised matrix cut-off values are built in the system to provide a variety of search modes of different stringency. The user may construct and save his/her specific user profiles which are selected subsets of matrices including default or user-defined cut-off values. Furthermore a number of tissue-specific profiles are provided that were compiled by the TRANSFAC team. A public version of the Match tool is available at: http://www.gene-regulation.com/pub/programs.html#match. The same program with a different web interface can be found at http://compel.bionet.nsc.ru/Match/Match.html. An advanced version of the tool called Match Professional is available at http://www.biobase.de.

Abstract
The TRANSFAC database on eukaryotic transcriptional regulation, comprising data on transcription factors, their target genes and regulatory binding sites, has been extended and further developed, both in number of entries and in the scope and structure of the collected data. Structured fields for expression patterns have been introduced for transcription factors from human and mouse, using the CYTOMER database on anatomical structures and developmental stages. The functionality of Match, a tool for matrix-based search of transcription factor binding sites, has been enhanced. For instance, the program now comes along with a number of tissue-(or state-)specific profiles and new profiles can be created and modified with Match Profiler. The GENE table was extended and gained in importance, containing amongst others links to LocusLink, RefSeq and OMIM now. Further, (direct) links between factor and target gene on one hand and between gene and encoded factor on the other hand were introduced. The TRANSFAC public release is available at http://www.gene-regulation.com. For yeast an additional release including the latest data was made available separately as TRANSFAC Saccharomyces Module (TSM) at http://transfac.gbf.de. For CYTOMER free download versions are available at http://www.biobase.de:8080/index.html.

Abstract
Based on the contents of the database S/MARt DB, the most comprehensive data collection of scaffold/matrix-attached regions (S/MARs) publicly available thus far, we initiated a systematic evaluation of the stored data. By analyzing the 245 S/MAR sequences presently described in this database, we found that the S/MARs contained in this collection are generally AT-rich, with certain significant exceptions. Comparative analyses showed that most of the AT-rich motifs which were found to be enriched in S/MARs are also enriched in randomized S/MAR sequences of the same AT content. Some sequence patterns previously suggested to be characteristic for S/MARs were also investigated, among them potential binding sites for homeodomain transcription factors. Even though hexanucleotides containing the core motif of homeodomain factors were frequently observed in S/MARs, only a few potential binding sites for these factors were found enriched when compared with regulatory regions or exon sequences. All our analyses indicated that, on average, the observed frequency of motifs in S/MAR elements is largely influenced by the AT content. Our results can serve as a guideline for further improvements in the definition of S/MARs, which are now believed to constitute the functional coordinate system for genomic regulatory regions.

Abstract
The aim of our study was to evaluate the influence of low-intensity exercise on levodopa absorption and levodopa motor effect. We studied the pharmacokinetics and pharmacodynamics of levodopa under resting conditions and under a workload of 50 watts for 2 hours on a cycle ergometer in 12 parkinsonian patients with predictable fluctuations of motor disability. The patients attended the hospital on both days in a provoked off state. After a baseline assessment of motor disability using the Columbia University rating scale (CURS scale) and a blood test for measurement of the baseline levodopa concentration in the plasma, 100 mg levodopa and 25 mg benserazide were administered as a single dose orally. Blood samples for measurement of the levodopa concentration in the plasma were taken, and motor assessments were conducted at 15-minute intervals for 240 minutes and at 30-minute intervals from 240 to 360 minutes. All patients were able to perform the exercise program. The baseline Columbia University rating scale score did not differ significantly between both days. The mean levodopa concentration in plasma at half-maximal motor effect tended to be higher during exercise and indicated that the patients needed a higher levodopa concentration in plasma to achieve the half-maximal motor effect. The maximal levodopa concentration in plasma tended to be higher with exercise. Both trends did not reach statistical significance. In summary, there was not a negative or a positive net effect of exercise on pharmacokinetics and pharmacodynamics of levodopa. However, there were two counteracting trends: a trend toward better levodopa absorption and a trend toward a deteriorated concentration-effect correlation.

Abstract
The introduction of digital X-ray techniques offered a variety of new possibilities for digital image enhancement and exposure reduction. In order to compare the reproducibility of cephalometric landmarks on conventional and digital lateral headfilms 100 digital and 100 conventional lateral headfilms of patients attending our clinic were randomly selected. The digital cephalograms were obtained using storage phosphor plates in standard X-ray cassettes. All X-rays had been taken at 77 kV. For the digital images the mAs settings for conventional images minus 4 mAs were used. Two orthodontists traced each X-ray twice (21 reference points) at an interval of at least 1 week. The tracings were superimposed and the distances between the tracings of identical reference points were registered. The average reproducibility of cephalometric landmarks was significantly higher on the digitally obtained images, despite a reduction of radiation exposure of 23.7% in the digital images.

Abstract
AIM To evaluate the suitability of panoramic radiographs obtained with two different machines for clinical use. MATERIAL AND METHODS Three observers assessed 111 pairs of panoramic radiographs taken with the Scanora (Soredex, Orion Corp., Helsinki, Finland) programme 001, and the Orthophos Plus (Sirona, Bensheim, Germany), programme P1 respectively, for visualisation of seven anatomical structures on each side, on a 5-point scale where 1 = very good. The median values were computed and a descriptive analysis performed. Interrater and intrarater agreement were expressed as weighted kappa. RESULTS The median values of both Scanora and Orthophos radiographs were the same, scoring 2. The intra- and inter-observer agreement was generally poor and similar for both machines. CONCLUSIONS The two panoramic machines were both given good ratings for evaluation of anatomical structures. The differences were very small and suggest that both machines are suitable for clinical use.

Abstract
Huntington's disease is characterised by hyperkinetic movements, mainly chorea, cognitive dysfunction, and psychiatric abnormalities. Non-dopa responsive parkinsonism occurs in the later stages of choreic disease or as the predominant feature of juvenile patients (Westphal variant). Late onset Huntington's disease presenting as levodopa responsive parkinsonism is rare. A series of four patients with late onset Huntington's disease presenting as levodopa responsive parkinsonism and cardiovascular dysautonomia, initially misdiagnosed as multiple system atrophy (MSA) in three patients, is reported. Levodopa treatment did not unmask significant chorea. These cases suggest the presence of a distinct phenotypic variant of Huntington's disease to be added to the differential diagnosis of other akinetic rigid syndromes.

Abstract
TRANSFAC is a database on transcription factors, their genomic binding sites and DNA-binding profiles (http://transfac.gbf.de/TRANSFAC/). Its content has been enhanced, in particular by information about training sequences used for the construction of nucleotide matrices as well as by data on plant sites and factors. Moreover, TRANSFAC has been extended by two new modules: PathoDB provides data on pathologically relevant mutations in regulatory regions and transcription factor genes, whereas S/MARt DB compiles features of scaffold/matrix attached regions (S/MARs) and the proteins binding to them. Additionally, the databases TRANSPATH, about signal transduction, and CYTOMER, about organs and cell types, have been extended and are increasingly integrated with the TRANSFAC data sources.
