Influence of heart rate in the selection of the optimal reconstruction window in routine clinical multislice coronary angiography
2008
Purpose. The aim of our study was to assess the influence of heart rate on the selection of the optimal reconstruction window with 40-slice multidetector-row computed tomography (40-MDCT) coronary angiography. Materials and methods. We studied 170 patients (114 men, age 60 +/- 11.3 years) with suspected or known coronary artery disease with 40-MDCT coronary angiography. Patients [mean heart rate (HR) 62.9 +/- 9.3 bpm, range 42-94 bpm] were clustered in two groups (group A: HR <= 65 bpm; group B: HR >65 bpm). Multiphase reconstruction data sets were obtained with a retrospective electrocardiogram (ECG)-gated 40-MDCT coronary angiography scan from 0% to 95% every 5% of the R-R interval.…

Patient(s) A 33-year-old woman with a 2-year history of primary infertility. Intervention(s) Controlled ovarian hyperstimulation and ICSI treatment with single-embryo transfer. Main Outcome Measure(s) Incidence of monozygotic twinning at the IVI clinics. Result(s) We report a twin pregnancy after a single-embryo transfer. Twins were di…
Effects of transcranial direct current stimulation on esophageal motility in patients with gastroesophageal reflux disease
2014
To evaluate the effects of transcranial direct current stimulation (tDCS) on esophageal peristalsis in patients with gastroesophageal reflux disease (GERD).Patients with GERD preliminary diagnosis were included in a randomized double-blind sham-controlled study. Esophageal manometry was performed before and during transcranial direct current stimulation (tDCS) of the right precentral cortex. Half of patients were randomly assigned to anodal, half to sham stimulation. Distal waves amplitude and pathological waves percentage were measured, after swallowing water boli, for ten subsequent times. Last, a 24h pH-bilimetry was done to diagnose non-erosive reflux disease (NERD) or functional heartb…
Physical activity, morbidity and mortality in twins: a 24-year prospective follow-up.
2010
The aim of this study was to find out whether persistent leisure-time physical activity, adjusted for genetic liability and childhood experiences, protect against occurrence of specific chronic diseases and all-cause mortality. Study design was a 24-year prospective follow-up after 6-year physical activity discordance in twin pairs. From 5,663 healthy adult twin pairs, 146 pairs (including 29 mozygotic) discordant for both intensity and volume of leisure physical activity at baseline in both 1975 and 1981 were systematically identified. Mortality and occurrence of chronic diseases (diabetes, hypertension, coronary heart disease defined according to reimbursable medication status) were follo…
Effects of oxygen fraction in inspired air on force production and electromyogram activity during ergometer rowing
1997
Six male rowers rowed maximally for 2500 m in ergometer tests during normoxia (fractional concentration of oxygen in inspired air, F IO2 0.209), in hyperoxia (F IO2 0.622) and in hypoxia (F IO2 0.158) in a randomized single-blind fashion. Oxygen consumption (V˙O2), force production of strokes as well as integrated electromyographs (iEMG) and mean power frequency (MPF) from seven muscles were measured in 500-m intervals. The iEMG signals from individual muscles were summed to represent overall electrical activity of these muscles (sum-iEMG). Maximal force of a stroke (F max) decreased from the 100% pre-exercise maximal value to 67 (SD 12)%, 63 (SD 15)% and 76 (SD 13)% (P<0.05 to normoxia, AN…
Repetitive TMS over the left dorsolateral prefrontal cortex modulates the error positivity: An ERP study
2019
Abstract Error processing is a critical step towards an efficient adaptation of our behavior to achieve a goal. Little research has been devoted to investigate the contribution of the dorsolateral prefrontal cortex (DLPFC) in supporting error processing. In this study, the causal relationship of the DLPFC in error commission was examined by means of a repetitive transcranial magnetic stimulation protocol (rTMS). Specifically, the effects of an inhibitory protocol were assessed by examining the electroencephalographic signal recorded during the execution of a Go/No-Go task. To this aim, a group of 15 healthy young participants performed a three-session study. At each session, either the righ…
The influence of extra load on the mechanical behavior of skeletal muscle
1984
Eleven international jumpers and throwers engaged in year round training were divided into experimental (n = 6) and control (n = 5) groups. The experimental group was tested before and after a 3 weeks simulated hypergravity period, and again 4 weeks after the hypergravity period. The high gravity condition was created by wearing a vest weighing about 13% of the subjects body weight. The vest was worn from morning to evening including the training sessions, and only removed during sleep. The daily training of all subjects consisted of classical weight training and jumping drills. No changes in the ordinary training program were allowed in the experimental group, except for the use of the ves…
Retrobulbar adipocytes and humoral immunity in Graves' ophthalmopathy
1993
As CT and MR-imaging revealed an enlargement of retrobulbar fat tissue in patients with Graves' ophthalmopathy, the role of the retrobulbar adipocytes in the pathogenesis of this disorder remains to be elucidated. To evaluate the in vitro influence of humoral immunity on retrobulbar adipose tissue, the effects of IgG and sera from 56 euthyroid ophthalmopathy patients and 53 controls on both porcine and human (patients' and controls') retrobulbar adipocytes were measured by means of several assays: An enzyme-linked immunosorbent assay was employed to reveal specific binding of antibodies to the adipocytes. Metabolic activity was determined by means of a colorimetric dimethyl thiazolium-diphe…
Local neck symptoms before and after thyroidectomy: a possible correlation with reflux laryngopharyngitis
2010
Objective Local symptoms in the neck such as swallowing, voice disorders and throat discomfort might be related to a goiter if present, but are also reported by patients suffering from reflux laryngopharyngitis. The aim of our study was to investigate the presence of reflux laryngopharyngitis in patients with nodular goiter before and after uncomplicated total thyroidectomy (TT) in order to evaluate if its presence could have any role in the origin of swallowing and voice alterations and throat discomfort. Study Design case series prospective study Setting hospitalized care in University Hospital Patients and Methods We consider twenty-five patients, affected by non-toxic nodular goiter and…
Genetic and environmental contributions to plasma C-reactive protein and interleukin-6 levels--a study in twins.
2006
Elevated baseline levels of acute-phase proteins such as C-reactive protein (CRP) or cytokines like interleukin-6 (IL-6) are known risk factors for atherosclerosis and cardiovascular disease (CVD) events. However, until today, there is only controversial information about the contribution of genetic and environmental factors. Therefore, we performed an open prospective study in 108 monozygotic (MZ) and 60 same-sex dizygotic (DZ) twin pairs to analyse the genetic and environmental contributions to plasma CRP and IL-6 levels. Heritability of IL-6 was 0.61, indicating that plasma IL-6 levels are to a major part influenced by genetic determinants; however, for CRP, heritability was only 0.22, p…
