The mutation responsible for the high bone mass (HBM) phenotype has been postulated to act through the adaptive response of bone to mechanical load resulting in denser and stronger skeletons in humans and animals. The bone phenotype of members of a HBM family is characterized by normally shaped bones that are exceptionally dense, particularly at load(More)
The efficacy and side effects of hydroxyurea in young children with sickle cell disease are unknown. The authors followed-up eight young children (mean age 3.7 years) during therapy with hydroxyurea for an average of 137 weeks. Total and fetal hemoglobin levels rose with hydroxyurea therapy. Hospital admission rates and total hospital days decreased during(More)
BACKGROUND Delirium is prevalent in surgical and trauma intensive care units (ICUs) and carries substantial morbidity. This study tested the hypothesis that daily administration of a diagnostic instrument for delirium in a surgical/trauma ICU decreases the time of institution of pharmacologic therapy and improves related outcomes. METHODS Controlled trial(More)
Audiogenic seizure (AGS) susceptibility in mice is a multifactorial behavioral disorder that involves severe generalized convulsions in response to loud, high-frequency sound. The inheritance of AGS susceptibility was examined in crosses between AGS-susceptible DBA/2J (D2) mice and epilepsy-prone (EP) mice. The EP mice were selected for high AGS(More)
A Ca(2+)- or Mg(2+)-stimulated ecto-ATPase is thought to regulate the hydrolysis of extracellular ATP in nervous tissues. The hydrolysis of nucleotide triphosphates (NTPs) was analyzed in brain microsomal fractions from crosses of DBA/2J (D2) and C57BL/6J (B6) mice. The nucleotide triphosphatase (NTPase) activity was significantly reduced in D2 mice as(More)
