BACKGROUND Segmental tissue loss in the lateral meniscus is associated with pain and increased risk of osteoarthritis even when indications have been carefully considered. HYPOTHESIS Repairing the defect using a novel biodegradable scaffold will reduce pain and restore the knee function. METHODS In this prospective multicenter study, a total of 54(More)
This study was undertaken to investigate the influence of exercise intensity (running speed) on a number of alterations that are known to occur with exercise training. Rats were trained on three treadmill running schedules: 20 m/min, 27 m/min, and 35 m/min for 1 h/day. After 6 wk, lean body mass and body fat content were decreased to the same extent in all(More)
Functional imaging computational fluid dynamics simulations of right ventricular (RV) inflow fields were obtained by comprehensive software using individual animal-specific dynamic imaging data input from three-dimensional (3-D) real-time echocardiography (RT3D) on a CRAY T-90 supercomputer. Chronically instrumented, lightly sedated awake dogs (n = 7) with(More)
We describe a novel functional imaging approach for quantitative analysis of right ventricular (RV) blood flow patterns in specific experimental animals (or humans) using real-time, three-dimensional (3-D) echocardiography (RT3D). The method is independent of the digital imaging modality used. It comprises three parts. First, a semiautomated segmentation(More)
OBJECTIVE Our purpose was to evaluate the efficacy of amoxicillin as an alternative therapy to erythromycin for the treatment of cervical chlamydial infections during pregnancy. STUDY DESIGN A randomized, prospective trial of two treatment regimens for Chlamydia trachomatis was performed in a cohort of pregnant women enrolled for care in an inner-city,(More)
Epoprostenol is a potent arterial vasodilator, and its administration by inhalation localizes its effects to the pulmonary circulation. In this case report, we describe a 3-month-old male patient with significant refractory pulmonary hypertension after pulmonary artery banding and placement of a Blalock-Taussig shunt. This patient continued to have(More)
OBJECTIVE The purpose of this study was to establish the relationship of plasma levels of brain natriuretic peptide (BNP) to physiologic parameters and cardiac morphologic characteristics in a population of young athletes. Our hypothesis is that physiologic and cardiac morphologic characteristics do not predict BNP levels in adolescent athletes. DESIGN(More)
A study on creativity in Texas Cooperative Extension (TCE) was conducted in 2004 in response to increasing interests in creative thinking in academia and industry and the inclusion of creative requisites in county agent performance and promotion measures. State and mid-level TEC administrators were given an e-mail questionnaire to determine attributes of(More)
