OBJECTIVES To analyze the effects of 3 months active therapy on gross back muscle size and muscle fiber type characteristics and their relationship to changes in muscle function. SUMMARY OF(More)
Parvalbumin (PV) is a high affinity Ca(2+)-binding protein found at high concentration in fast-contracting/relaxing skeletal muscle fibers of vertebrates. It has been proposed that PV acts in the process of muscle relaxation by facilitating Ca2+ transport from the myofibrils to the sarcoplasmic reticulum. However, on the basis of metal-binding kinetics of(More)
CONTEXT For more than two decades, abstinence from sexual intercourse has been promoted by some advocates as the central, if not sole, component of public school sexuality education policies in the United States.

The pain did neither increase during breathing nor decrease after the ingestion of nitroglycerine, and could not be triggered by physical manipulation of the thoracic wall. Electrocardiogram showed a left bundle branch block, chest X-ray(More)
Many studies have documented an association between chronic low back pain (LBP) and deficits in back muscle strength and endurance. The sub-optimal performance is believed to be the result of alterations in the size and structure of the muscle, although the long-standing issue of whether the observed changes precede or are a consequence of the pain remains(More)
The Alan Guttmacher Institute takes a critical look at the practical aspects of obtaining and providing the hormonal implant Norplant in the US service delivery system. It focuses on financial accessibility of the implant and raises questions about the role of service providers in implant counseling and removal. In the US, access to a complete range of(More)
Eosinophilia has been encountered from 0.2 to 61.7% in clozapine-treated patients, mostly with a transient course and spontaneous remission. There have been few reports, however, which have investigated a challenge with clozapine in patients previously showing eosinophilia. Two case reports are presented: the first with clozapine challenge after(More)
