Hypertension is associated with endothelial dysfunction that is attributable to oxidative stress and a proinflammatory state. Under these conditions, enhanced expression of cyclooxygenase-2 might lead to increased production of vasoconstrictor prostanoids and reactive oxygen species that reduce the bioavailability of endothelium-derived nitric oxide. To… (More)
BACKGROUND Recurrent pregnancy loss may result from hypercoagulability. OBJECTIVE To determine whether women with factor V Leiden mutation, a common inherited defect of coagulation, are at increased risk for recurrent pregnancy loss. DESIGN Case-control study. SETTING University hospital. PATIENTS 113 consecutive women referred for evaluation of… (More)
Fifty-nine subjects 5-16 years old with major depressive disorder were assessed for the presence of separation anxiety and antisocial behavior, mentioned in DSM-III as associated features of the disorder in children and adolescents. The findings of the study support the existence of these associated features.
The use of nortriptyline single dose kinetics to predict steady state plasma levels and suggested dose was investigated in 33 pediatric subjects who were diagnosed as having major depressive disorder. The data were analyzed separately for the 11 subjects 5 to 9 years old who received a single dose of 25 mg and a fixed daily dose of 20 mg of nortriptyline,… (More)
BACKGROUND A single point mutation in the gene coding for coagulation factor V results in a form of factor Va that is resistant to degradation by activated protein C and leads to a relative hypercoagulable state. This mutation, factor V Leiden, is found in 4% to 6% of the U.S. population. PURPOSE To review clinical data on factor V Leiden mutation, with… (More)
NO is an important component of vascular homeostasis and abnormal NO bioactivity has been implicated in number of disease states with important public health implications. One clear mechanism of impaired NO bioactivity and vascular disease is excess vascular oxidative stress. There is now a wealth of developing data that manipulation of vascular antioxidant… (More)
The effect of long-term arm exercise on cardiac morphology and function is unknown. To study these effects, highly trained wheelchair athletes were compared with long-distance runners and controls. In addition, the wheelchair athletes were compared with the long-distance runners to determine if long-term leg exercise confers a training effect during the… (More)
