Chronic airflow limitation, caused by chronic obstructive pulmonary disease (COPD) or by asthma, is believed to change the shape and the position of the diaphragm due to an increase in lung volume. We have made a comparison of magnetic resonance imaging (MRI) of diaphragm in supine position with pulmonary functions, respiratory muscle function and exercise tolerance. We have studied the differences between patients with COPD, patients with asthma, and healthy subjects. Most interestingly we found the lung hyperinflation leads to the changes in diaphragmatic excursions during the breathing cycle, seen in the differences between the maximal expiratory diaphragm position (DPex) in patients with COPD and control group (p=0...

Lotus seedpod proanthocyanidins (LSPC) as a kind of polyphenols is widely used in medicines, cosmetics, health products. High-intensity exercise can cause damage to the body's organs and tissues. Different doses of LSPC is given to mice to check the function of protect effect to the body's organs and tissues under high-intensity exercise. The hemoglobin (HB) content, red blood cell (RBC) number and white blood cell (WBC) number were tested for mice after exercise. The activity of superoxide dismutase (SOD) and the contents of glutathione (GSH) and malondialdehyde (MDA) in muscle and viscera were evaluated...

Primary lymphedema can be managed effectively as a form of chronic lymphedema by a sequenced and targeted treatment and management program based around a combination of Decongestive Lymphatic Therapy (DLT) with compression therapy, when the latter is desired as an adjunct to DLT. Treatment in the maintenance phase should include compression garments, self-management, including self-massage, meticulous personal hygiene and skin care, in addition to lymphtransport-promoting excercises and activities, and, if desired, pneumatic compression therapy applied in the home...

Interleukin-6 (IL-6) plays a central role in the pathogenesis of multiple myeloma, acting both as a growth and a survival factor for myeloma cells. IL-6 has been recently shown to possess three topologically distinct receptor binding sites: site 1 for binding to the subunit specific chain IL-6R alpha and sites 2 and 3 for the interaction with two separate subunits of the signalling chain gp130. We have generated a set of IL-6 receptor antagonists carrying substitutions that abolish interaction with gp130 at either site 2 alone (site 2 antagonist) or at both sites 2 and 3 (site 2+3 antagonist)...

BACKGROUND: Myasthenia gravis (MG) is a disease with autoimmune background. Impaired neuromuscular transmission is caused by blockage of acetylcholine receptors on postsynaptic membrane by circulating specific antibodies. Recognition of myasthenia gravis in children, especially its ocular type, may be difficult due to occurrence of similar clinical symptoms in other diseases like ecephalomyopathies. MG is characterized by variety of clinical symptoms and their alternations during excercise and rest...

Primary lymphedema can be managed safely as one of the chronic lymphedemas by a proper combination of DLT with compression therapy. Treatment in the maintenance phase should include compression garments, self management including the compression therapy, self massage and meticulous personal hygiene and skin care in addition to lymph-transport promoting excercises. The management of primary lymphedema can be further improved with proper addition of surgical therapy either reconstructive or ablative. These two surgical therapies can be effective only when fully integrated with MLD-based DLT postoperatively...

Mitochondrial DNA (mtDNA) mutations accumulate in the skeletal muscle of patients with mtDNA disease, and also as part of healthy ageing. Simulations of human muscle fibres suggest that, over many decades, the continuous destruction and copying of mtDNA (relaxed replication) can lead to dramatic changes in the percentage level of mutant mtDNA in non-dividing cells through random genetic drift. This process should apply to both pathogenic and neutral mutations. To test this hypothesis we sequenced the entire mitochondrial genome for 20 muscle fibres from a healthy elderly 85-year-old individual, chosen because of the low frequency of cytochrome c oxidase negative fibres...

Few muscle disorders can be diagnosed by repetitive nerve stimulation (RNS). Decreasing compound muscle action potentials (CMAP) on high frequency RNS is recorded in muscle channelopathies, and particularly in sporadic and recessive congenital myotonia. In this myopathy, decreasing CMAP after exercise test and RNS are the most sensitive electrophysiological in detecting muscle membrane dysfunction and are considered highly informative even in mildly symptomatic patients. We report on a patient with excercise-induced diffuse muscle cramps and myalgia; muscle biopsy and laboratory investigations were normal...

Non-genomic effects of aldosterone on oxidative metabolism of skeletal muscle have been shown, recently. To further characterize these rapid effects on the increase of phosphocreatine (PCr) in the recovery period after isometric exercise, a randomized cross-over placebo-controlled study was conducted on 9 healthy volunteers. Hypoxia was chosen to test the dependence of the effect on oxygen supply and thus its relation to oxidative vs non-oxidative metabolism. Parameters related to the energy metabolism of calf muscles were measured by 31P magnetic resonance spectroscopy during four repetitive contractions in four different tests (hypoxia [FiO2=0...

UNLABELLED: Aging increases certain thrombotic risk factors, such as fibrinogen, factor VII, PAI-1 and plasma viscosity, contributing to cardiovascular diseases being the principal cause of death in developed countries. Physical exercise can counteract this tendency by influencing such factors. PURPOSE: To assess the effect of regular physical exercise on fibrinogen, factor VII, PAI-1 and plasma viscosity in an elderly group. METHODS: Sixty-three old people of both sexes, aged between 65 and 94, participated in this study, and were randomly distributed between a test group (n = 31) and a control group (n = 32)...

Ten young (aged 23-30 years) and nine older (aged 54-59 years) healthy men with a similar size of limb muscle mass performed arm crank and leg cycle exercise for 30 min at relative exercise intensities of 50% and 75% of maximal oxygen uptake for the corresponding muscle group. In the tests, heart rate, blood pressure, gas exchange variables, rating of perceived exertion and blood lactate concentration were measured. The limb muscle mass was determined by anthropometric measurements. At the 75% target exercise level, four of the older men and two of the young men could not complete the arm-cranking test, and one of the older men and two of the young men could not complete the leg-cycle test...

Exercise training has been shown to be effective in preventing the development of non-insulin-dependent diabetes mellitus (NIDDM) in a model rat (Otsuka-Long-Evans-Tokushima Fatty [OLETF]). For determination of how long a preventive effect of exercise training against the development of NIDDM lasts in this model, six male OLETF rats each were assigned to training (1) for a whole experimental period, from 7 to 28 weeks of age (E-E); (2) for the first half of the period, from 7 to 15 weeks of age (E-S); and (3) for the second half of the period, from 16 to 28 weeks of age (S-E)...

Forty-nine patients undergoing cardiac catheterization for suspected coronary artery disease (CAD) were monitored with a two-channel ambulatory ECG and were given maximal treadmill exercise tests when these were not contraindicated. The ambulatory ECG recordings were evaluated for the number of ST segment deviations after correction for positional changes, and the results were then compared with those of the exercise test and coronary angiography. Sensitivity and specificity of ambulatory ECG monitoring for ST segment deviations to detect CAD were 76% and 75% respectively while those of exercise testing were 78% and 63% respectively...

Exercise stimulation tests for growth hormone were performed in two groups of children: 163 patients aged 4 to 20 years had growth hormone measured before and after exercise, and 28 children had growth hormone checked only after excercise. Of 180 exercise stimulation tests performed in the first group, 124 showed an adequate growth hormone response as did 23 of 29 such tests in the second group. Careful instruction and preparation of patients for exercise screening of growth hormone leads to an accuracy for this test of nearly 80 percent...
