    ABSTRACT: We examined the effects of different shift work schedules and chronic mild stress (CMS) on mood using animal model. The most common international shift work schedules in nursing were applied by three groups of Wistar-rats and a control group with normal light-dark cycle. One subgroup from each group was subjected to CMS. Levels of anxiety and emotional life were evaluated in light-dark box. Differences between the groups according to independent and dependent variables were examined with one- and two-way analysis of variance, with a significance level defined at p < 0.05. Interaction of lighting regimen and CMS was proved to be significant according to time spent in the light compartment and the average number of changes between the light and dark compartments. Results of our examination confirm that the changes of lighting conditions evocate anxiety more prominently than CMS. No significant differences were found between the results of the low rotating group and the control group, supposing that this schedule is the least harmful to health. Our results on the association between the use of lighting regimens and the level of CMS provide evidence that the fast rotating shift work schedule puts the heaviest load on the organism of animals.

    ABSTRACT: The glomerular filtration barrier is a highly specialized tri-layer structure with unique functional properties. Podocyte dysfunction and cytoskeletal disorganization leads to disruption of the slit diaphragma, and proteinuria. Inflammatory diseases involving the kidney as well as inherited podocytopathies or diabetic nephropathy cause injury of the podocyte network. Focal segmental glomerulosclerosis (FSGS) is a pathologic entity that is a common cause of nephrotic syndrome with severe proteinuria in both adults and children. Several causative genes have been identified in the pathogenesis of FSGS. Mutations of the transient receptor potential canonical-6 (TRPC6), a non-selective cation channel that is directly activated by diacylglycerol (DAG), cause a particularly aggressive form of FSGS. Angiotensin II, acting through its AT1 receptor, plays a critical role in generation of proteinuria and progression of kidney injury in a number of kidney diseases, including FSGS. Mounting evidence suggest the central role of TRPC6 and perhaps other TRPC channels in the pathogenesis of FSGS as well as of acquired forms of proteinuria such as diabetic nephropathy or hypertension. Identification of signaling pathways downstream of TRPC6 may provide novel targets for the treatment of proteinuria and prevent progression of podocyte injury.

    ABSTRACT: Several studies state that there might be a difference in the physical development and the motor performance of the mentally non-handicapped children and those with intellectual and development disabilities. The aim of our research was to compare the two groups from these aspects. The study included the assessment of the physical development and motor performance of altogether 225 primary school pupils (mentally non-handicapped and with intellectual and development disabilities) aged 8-11. The following indicators of physical development and build were examined: body height, body weight and body mass index (BMI), musculoskeletal plasticity index, biceps and triceps skinfold thickness. The motor tests included: 20 m dash, standing long jump, medicine-ball throwing, six minutes continuous running, obstacle race-test and a match test. We also examined the children's chronological (decimal) and morphological age. Data were analysed with SPSS programme. The differences between the averages were calculated with ANOVA and Fisher's LSD tests. The results show that the children with intellectual and development disabilities are in general less developed physically than non-handicapped children of the same age and sex. It is also concluded that in most motor tests the children with intellectual and development disabilities fall behind the non-handicapped ones.

    ABSTRACT: To investigate whether heat stress attenuates skeletal muscle atrophy of the extensor digitorum longus (EDL) muscle in streptozotocin-induced diabetic rats, 12-week-old male Wistar rats were randomly assigned to four groups (n = 6 per group): control (Con), heat stress (HS), diabetes mellitus (DM), and diabetes mellitus/heat stress (DM + HS). Diabetes was induced by intraperitoneal injection of streptozotocin (50 mg/kg). Heat stress was induced in the HS and DM + HS groups by immersion of the lower half of the body in hot water at 42 °C for 30 min; it was initiated 7 days after injection of streptozotocin, and was performed once a day, five times a week for 3 weeks. The muscle fiber cross-sectional area of EDL muscles from diabetic and non-diabetic rats was determined; heat stress protein (HSP) 72 and HSP25 expression levels were also analyzed by western blotting. Diabetes-induced muscle fiber atrophy was attenuated upon heat stress treatment in diabetic rats. HSP72 and HSP25 expression was upregulated in the DM + HS group compared with the DM group. Our findings suggest that heat stress attenuates atrophy of the EDL muscle by upregulating HSP72 and HSP25 expression.

    ABSTRACT: Purpose The reported magnitude of plasma volume increase (Δ%PV) following heat acclimation (HA) varies widely. Variations may result from differences in measurement techniques, season and subjects' fitness. This report compares direct and indirect measurements of Δ%PV after 10 days of HA from studies in winter (WIN, n = 8) and summer (SUM, n = 10) in men, age 21-43 yr, at two fitness levels (VO2max: 35 and 51 ml/min/kg). Direct measurements were made before and after HA (cycling at 30% of VO2max at 50 °C, for 100 min/day) by carbon monoxide (CO) rebreathing and compared with indirect estimates from changes in hematocrit, hemoglobin and plasma protein concentration. Results Overall, Δ%PV by CO was small (2.9%) and greater in SUM than WIN (5.0 vs. 0.3%). Red cell, blood and plasma volumes/kg lean body mass increased in SUM and decreased in WIN, the difference being significant, and Δ%PV by CO was similar for high and low VO2max. Conclusion Overall, indirect estimates of Δ%PV by hemoglobin and hematocrit were similar to CO, but tended to differentiate by fitness and not season. The difference in THb increase in SUM and decrease in WIN was significant. This probably accounts for the differences from the seasonal and fitness results by the direct CO method.

    ABSTRACT: The purpose of the present study was to examine how oscillation of tissue oxygen index (TOI) in non-exercising exercise is affected during high-intensity and low-intensity exercises. Three exercises were performed with exercise intensities of 30% and 70% peak oxygen uptake (Vo2peak) for 12 min and with exercise intensity of 70% Vo2peak for 30 s. TOI in non-exercising muscle (biceps brachii) during the exercises for 12 min was determined by nearinfrared spectroscopy. TOI in the non-exercising muscle during the exercises was analyzed by fast Fourier transform (FFT) to obtain power spectra density (PSD). The frequency at which maximal PSD appeared (Fmax) during the exercise with 70% Vo2peak for 12 min (0.00477 ± 0.00172 Hz) was significantly lower than that during the exercise with 30% Vo2peak for 12 min (0.00781 ± 0.00338 Hz). There were significant differences in blood pH and blood lactate between the exercise with 70% Vo2peak and the exercise with 30% Vo2peak. It is concluded that TOI in nonexercising muscle oscillates during low-intensity exercise as well as during high-intensity exercise and that the difference in Fmax between the two exercises is associated with the difference in increase in blood lactate derived from the exercise.

    ABSTRACT: We studied effects of therapeutic riding on the development of children with autism. Experiments in walking is appropriate for assessing the coordination of movement and for following the changes. We found that therapeutic riding should be considered as a new form of rehabilitation. Twenty-six pupils (12 boys and 14 girls) of a special needs school participated in therapeutic riding. We analyzed walking twice during a school-term: full body analyses each time before and after one-month therapy. The research included a non-riding control group. All together 104 analyses were performed. We measured mental skills using Pedagogical Analysis and Curriculum (PAC) test consisting of four parts being communication, self care, motor skills and socialization. The Gait Cycle Analysis consists of the time-series analysis, the analysis of part of the gait cycle and the measurement of joint angles in each plane. We found significant differences between before and after the therapy in the length of the gait cycle that became more stable in the sagital plane and concluded that our results proved that horse therapy may be successfully used as an additional therapy for children with autism, and it may be a form of rehabilitation in cases when other therapies are not successful.

    ABSTRACT: Tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute ST elevation myocardial infarction (STEMI). The primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly following successful recanalization therapy and magnetic resonance imaging (MRI)-derived myocardial tissue loss late after STEMI. The study comprised 29 STEMI patients. Videodensitometric parameter Gmax/Tmax was calculated to characterize myocardial perfusion, derived from the plateau of grey-level intensity (Gmax), divided by the time-to-peak intensity (Tmax). Myocardial loss index (MLI) was assessed by cardiac MRI following 376 ± 254 days after PCI. Signifcant correlations could be demonstrated between MLI and Gmax (r = 0.36, p = 0.05) and Gmax/Tmax (r = 0.40, p = 0.03) using vessel masking. Using receiver operating characteristic curve analysis, Gmax/Tmax < 2.17 predicted best MLI = 0.3, 0.4, 0.5 and 0.6 with good sensitivity and specifcity data, while Gmax/Tmax < 3.25 proved to have a prognostic role in the prediction of MLI = 0.7. Selective myocardial tissue level perfusion quantitative measurement method is feasible and can serve as a good predictor of myocardial tissue loss following STEMI and revascularization therapy.

    ABSTRACT: Expiratory flow limitation can develop in parallel with the progression of COPD, and as a consequence, dynamic hyperinflation and lung mechanical abnormalities can develop. Dynamic hyperinflation can cause increased breathlessness and reduction in exercise tolerance. Achievement of critical inspiratory reserve volume is one of the main factors in exercise intolerance. Obesity has specific lung mechanical effects. There is also a difference concerning gender and dyspnoea. Increased nerve activity is characteristic in hyperinflation. Bronchodilator therapy, lung volume reduction surgery, endurance training at submaximal intensity, and heliox or oxygen breathing can decrease the degree of dynamic hyperinflation.

    ABSTRACT: In Hungary, ECG is a keystone of routine athletic screening. Its signifcance is based on simplicity, quickness and high informative value as well as the fact that appearance of pathological ECG signs can precede the formation of structural heart diseases. During screening of healthy athletes, we studied the incidence of athletic ECG changes and pathological ECG abnormalities. We performed detailed analysis of 12-lead ECG recordings of asymptomatic elite, non-elite and master athletes and controls. 227 athletes (male: 180, age: 27.2±8.7 years) and 89 controls (male: 57, age: 28.1±6.8 years) were examined. Benign ECG signs: sinus bradycardia, early repolarization and isolated Voltage criteria of left ventricular hypertrophy were common and more often in athletes compared to controls. Potentially pathological ECG signs: ST- (6.6% vs. 1.1%, p < 0.05) and T-wave (15.0% vs. 5.6%, p < 0.05) changes and signs of pathological left ventricular hypertrophy (5.3% vs. 0%, p < 0.05) occurred more frequently in athletes compared to controls. Signs of pathological left ventricular hypertrophy and repolarization abnormalities are more often in athletes. No structural heart disease could be verifed in the background of the disorders. However, athletes having pathological ECG should be kept under tight cardiology control. Exact defnition and widespread knowledge of pathological ECG changes is essential in early recognition of high risk athletes.

    ABSTRACT: The purpose of this study was to determine whether tissue oxygen indices (TOIs) in two muscle groups oscillated and were synchronized in repetition of impulse exercise with high intensity. Five impulse exercises of 400 watts for 10 s were repeated with intervals of 6 min. During this period, TOI was determined by near-infrared spectroscopy in the vastus lateralis and gastrocnemius muscles. TOIs in the two muscles oscillated at rest. The TOIs rapidly decreased during each impulse exercise and then recovered and overshot after each impulse. The TOIs oscillated during each interval period. During this test period, coherent and phase differences were determined. There was high coherence between TOIs in the two muscles with a peak value at 0.019 Hz. There was a phase difference of -45 ± 32.4 degrees between TOIs in the two muscles. This phase difference corresponded to about 6 s in time scale. It seemed from this time delay that impulse exercise was not a trigger factor for the starting point of TOIs in the two muscles. It has been concluded that TOIs oscillate and are synchronized between two muscles in repetition of impulse exercise with high intensity.
