Infectious Causes of Chronic Fatigue Syndrome Infectious Causes of Chronic Fatigue Syndrome
Infectious Causes of Chronic Fatigue Syndrome Numerous studies have demonstrated a high incidence of chronic infections in chronic fatigue syndrome and fibromyalgia. These include viral infections of Epstein bar (EBV), cytomegalovirus (CMV), human h rpes virus6, (HHV-6), and bacterial infections such as mycoplasma, chlamydia pneumonia (CP) and Borrelia burgdorferi (Lyme disease). There is contr...
متن کاملNeurobiology of muscle fatigue.
Muscle fatigue encompasses a class of acute effects that impair motor performance. The mechanisms that can produce fatigue involve all elements of the motor system, from a failure of the formulation of the descending drive provided by suprasegmental centers to a reduction in the activity of the contractile proteins. We propose four themes that provide a basis for the systematic evaluation of th...
متن کاملNO more muscle fatigue.
NOS is a key enzyme in the production of NO, a molecule that directly regulates vasorelaxation and blood supply. Diverse forms of muscle disease have been clinically associated with unusual fatigue after exercise. The localization of neuronal NOS (nNOS) at the plasma membrane of muscle has recently been shown to prevent muscle fatigue after exercise. In this issue of the JCI, Lai et al. show th...
متن کاملAge-related resistance to skeletal muscle fatigue is preserved during ischemia.
During voluntary contractions, the skeletal muscle of healthy older adults often fatigues less than that of young adults, a result that has been explained by relatively greater reliance on muscle oxidative metabolism in the elderly. Our aim was to investigate whether this age-related fatigue resistance was eliminated when oxidative metabolism was minimized via ischemia induced by cuff (220 mmHg...
متن کاملCauses of fatigue in slow-twitch rat skeletal muscle during dynamic activity.
Skeletal muscle fatigue is most often studied in vitro at room temperature and is classically defined as a decline in maximum force production or power output, exclusively linked to repeated isometric contractions. However, most muscles shorten during normal use, and we propose that both the functional correlate of fatigue, as well as the fatigue mechanism, will be different during dynamic cont...
