D ental articulation is the relationship of adjacent and opposing teeth during function, and its study demands a thorough knowledge of the roles of the various parts of the chewing apparatus and their integration into the chewing act. In order to understand how teeth articulate, it is important to know the mechanics of jaw movement in function. This articlc will discuss the mandible as a lever ...

OBJECTIVE To evaluate whether timely adherence rates differ by race among women with abnormal Pap tests participating in a cost-free or reduced-cost program. METHODS Eligible subjects included women aged 47-64 years who received a referral for follow-up care after an abnormal Pap test from 1999 to 2002 in South Carolina (n=330). Adherence was measured as days to receipt of follow-up care afte...

The cholinergic system plays an essential role in brain development, physiology, and pathophysiology. Herein, we review how specific alterations this system, through genetic mutations or abnormal receptor function, can lead to aberrant neural circuitry that triggers disease. focuses on the nicotinic acetylcholine (nAChR) its addiction neurodegenerative neuropsychiatric diseases epilepsy. Cholin...

OBJECTIVES The study assessed changes in left ventricular systolic and diastolic function after pericardiectomy in patients with constrictive pericarditis and correlated postoperative Doppler echocardiographic findings with clinical status. BACKGROUND Despite the efficacy of pericardiectomy, some patients with constrictive pericarditis fail to improve postoperatively. Data on serial evaluatio...

Background Single ventricle (SV) physiology consists of a single pumping chamber that provides both systemic and pulmonary blood flow. The typical quantitative measurements of ventricular function (i.e. ejection fraction) cannot be accurately applied to single ventricles due to abnormal ventricular morphology. Cardiac Magnetic Resonance (CMR) has become a leading diagnostic tool in the assessme...
