The factors that determine the axial orientation and phenotypes of skin appendages were analyzed by studying the effect of retinoic acid (RA) on embryonic chicken skin explant cultures. With RA uniformly distributed in the culture media, the feather buds became smaller, were disoriented or were transformed into scale-like structures in a(More)
OBJECTIVE The objective was to describe the epidemiology of emergency department (ED) visits for attempted suicide and self-inflicted injury over a 16-year period. METHOD Data were obtained from the National Hospital Ambulatory Medical Care Survey including all visits for attempted suicide and self-inflicted injury (E950-E959) during 1993-2008. RESULTS(More)
Aberrant transcriptional inactivation of the non-X-linked human O-6-methylguanine DNA methyltransferase (MGMT) gene has been associated with loss of open chromatin structure and increases in cytosine methylation in the Sp1-binding region of the 5'-CpG island of the gene. To examine the necessity of these events for gene silencing, we have isolated and(More)
Despite the known risk, many people talk on a phone while driving. This study explored psychological predictors of cell phone use while driving. College students (final N=69) completed a survey and predicted their driving performance both with and without a simultaneous phone conversation. Their actual performance on a driving simulator was then assessed.(More)
Homeoproteins are functionally involved in pattern formation. Recently, homeoproteins have been shown to be distributed in a graded fashion in developing limb buds. Here we examine the expression of homeoproteins in chicken feather development by immunocytochemical localization. We find that XlHbox 1 antigen is present in cell nuclei and is distributed in a(More)
OBJECTIVES The Infectious Disease Society of America (IDSA) and American Thoracic Society (ATS) developed guidelines for the management of community-acquired pneumonia (CAP); however, there are sparse data on actual rates of antibiotic use in the emergency department (ED) setting. METHODS Data were obtained from the National Hospital Ambulatory Medical(More)
OBJECTIVES   The objective was to provide estimates and predictors of screening for suicide in emergency departments (EDs). METHODS   Eight geographically diverse U.S. EDs each performed chart reviews of 100 randomly selected patients, ages 18 years or older, with visits in October 2009. Trained chart abstractors collected information on patient(More)
Two distinctly different denial-based threat orientations (avoidance denial and optimistic denial) were examined using a message about the future risk of cardiovascular disease (CVD) for young adults. Participants (N = 101) completed measures of denial-based dispositional threat orientations, current eating, comparative risk, and objective risk for CVD.(More)
OBJECTIVES Current outpatient diagnostic algorithms for urinary tract infection (UTI) in older adults require the presence of classic signs and symptoms of UTI, such as fever and genitourinary symptoms. However, older adults with UTI may present with atypical signs and symptoms. The objective was to identify the associations of age and nursing home status(More)
OBJECTIVES Large-scale epidemiologic studies of meningitis in the emergency department (ED) setting are lacking. Using a nationwide sample, the authors determined the frequency of meningitis visits and characterize management. METHODS Using National Hospital Ambulatory Medical Care Survey (NHAMCS) data, 1993 through 2008, meningitis diagnoses were studied(More)
