Serotonergic modulation of hippocampal acetylcholine release after long-term neuronal grafting
2000
Adult female rats sustained aspirative fimbria-fornix lesions and, 2 weeks later, received intrahippocampal grafts of fetal septal or mixed septal-raphe cell suspensions. Twenty-four months later, the extracellular concentration of hippocampal acetylcholine (ACh) was determined by microdialysis. Basal ACh levels (5-65 fmol/5 microl sham-operated rats) were strongly reduced after lesioning (3-7 fmol/5 microl). In septally transplanted and septal-raphe co-transplanted rats, hippocampal ACh concentrations were restored to near-normal levels (15-25 fmol/5 microl), indicating long-term functional survival of hippocampal transplants. After administration of citalopram (100 microM by infusion) and…
VITOM® 3D system in surgeon microsurgical vascular training: our model and experience.

LETTER TO EDITOR
Training program for transanal endoscopic microsurgery.
1988
Televised endoscopy and the concept of the “assisted” endoscopic operation is of great help in teaching surgical endoscopic techniques. The use of training dummies provides a new method of training manual dexterity and surgical skills in special courses or in surgical skill laboratories. We have developed a training system for transanal endoscopic microsurgery. Operations with our technique were performed on 116 patients. Like other microsurgical techniques, our method requires a special introduction and intensive training. This paper presents our multistage, video-supported training course for teaching transanal endoscopic microsurgery. The one-day training session is divided into four ste…
Clinical Description of a Different Form of Tinnitus: Intermittent Tinnitus
2011
1. Intermittent (paroxysmal) tinnitus is a form of non-pulsatile tinnitus. 2. An intermittent nature can be the only sign that intermittent tinnitus is different from other forms of tinnitus. 3. Intermittent tinnitus may be accompanied by irregular symptoms of other neurotologic disorders. 4. Both objective and subjective tinnitus may be intermittent. 5. A wide range of pathologies may cause intermittent tinnitus, but the cause of most forms is unknown.
Perturbed Glucose Metabolism: Insights into Multiple Sclerosis Pathogenesis
2014
Multiple sclerosis (MS) is a complex debilitating disease of the central nervous system perceived to result from the autoimmune effect of T cells in damaging myelin sheath. However, the exact pathogenesis of the disease remains elusive. Initial studies describing the possibility of defective pyruvate metabolism in MS were performed in 1950s. The group observed elevated blood pyruvate level in both fasting and postprandial times in MS patients with relapse. Similarly, other investigators also reported increased fasting pyruvate level in this disease. These reports hint to a possible abnormality of pyruvate metabolism in MS patients. In addition, increase in levels of Krebs cycle acids like a…
Stay Home, Stay Active with SuperJump®: A Home-Based Activity to Prevent Sedentary Lifestyle during COVID-19 Outbreak
2020
The purpose of this study was to investigate the intensity of SuperJump® workout as a home-based activity for fulfilling physical activity recommendations during COVID-19 home-confinement. Seventeen (males: n = 10; females: n = 7) college students (age: 25.8 ± 2.7 years; height: 1.7 ± 0.1 m; weight: 66.2 ± 12.1 kg) participated in the study. To assess the intensity of the activity (30-min), heart rate (HR), expressed as percentages of age-predicted maximal HR (%HRmax), and session ratings of perceived exertion (sRPE), collected on a CR10 scale, were used. %HRmax data were categorically separated in five classes of intensity according to the American College of Sport…
Monitoring stress and recovery states: Structural and external stages of the short version of the RESTQ sport in elite swimmers before championships
2016
Background: Psychological stress and recovery monitoring is a key issue for increasing athletes' health, well-being, and performance. This multi-study report examined changes and the dose–response relationships between recovery–stress psychological states, training load (TL), heart rate (HR), heart rate recovery (HRR), and heart rate variability (HRV) while providing evidence for the factorial validity of a short French version of the Recovery–Stress Questionnaire for Athletes (RESTQ-36-R-Sport). Methods: Four hundred and seventy-three university athletes (Study 1), 72 full expert swimmers (Study 2), and 11 national to international swimmers (Study 3) participated in the study. Data were an…
Contribution of area 19 to the foreground-background-interaction of the cat: an analysis based on single cell recordings and behavioural experiments.
1990
The contribution of area 19 to pattern discrimination in the cat was studied by single cell recordings in this area and by behavioural experiments before and after bilateral lesions. In order to make quantitative comparisons between behavioural performance and that of cell systems, we introduced a new parameter that characterizes visual neurons by their signal-to-noise (S/N) thresholds. A structured visual background made up of Gaussian visual broadband noise which could be moved was superimposed on the signal (moving bars or outline patterns) and the S/N characteristics of the response were determined by varying the signal intensity. The detection performance of cats after bilateral lesion…
Chronical haloperidol and clozapine treatment in rats: Differential RNA display analysis, behavioral studies and serum level determination
1998
1. Adult, female rats were treated orally for 23 days with 1.6 mg/kg haloperidol or 36 mg/kg clozapine per day, to study chronic effects of the two neuroleptics. 2. At five time points during the neuroleptic treatment, animal behavior was recorded in an open field and locomotive activity was analysed. At the end of the experiment, rats were decapitated, blood samples were collected and serum concentrations of haloperidol and clozapine were determined by a radioreceptor or HPLC assay, respectively. RNA was isolated from each brain, without cerebellum, and subjected to differential RNA display. 3. Mean serum concentrations were 8 ng/ml for haloperidol and 21 ng/ml for clozapine. Analysis of o…
