The purpose of this study was to assess the test-retest stability of the Fagerstrom Tolerance Questionnaire (FTQ) in two samples: (a) paid subjects in an American laboratory; data were collected via telephone screen and subsequently via questions embedded in a written history; and (b) smokers hospitalized for depression in Paris; data were collected via a(More)
The Tridimensional Personality Questionnaire (TPQ) was developed by Cloninger (1986) to measure heritable variation in three patterns of response to environmental stimuli: novelty seeking, harm avoidance, and reward dependence. Cloninger (1987) used the TPQ to identify two types of alcoholism: Type 1 (low novelty seeking, high harm avoidance and reward(More)
PURPOSE To assess the ability of the urinary N-telopeptide of type I collagen (NTx) to monitor and predict therapeutic effects of hormone replacement therapy (HRT) in postmenopausal women. PATIENTS AND METHODS To assess the relationship between baseline or change in NTx (predictive variable), and change in lumbar and hip bone mineral density (BMD; outcome(More)
Biochemical markers of bone resorption are useful for evaluating metabolic bone diseases. A three-center study was performed in 253 men, 21-86 yr of age, to determine the normal range of urinary N-telopeptide of type I collagen (NTX/creatinine) in a nonfasting, second void, morning specimen, to define the biological variability and to examine the(More)
The present report describes anIntranasalNicotineAerosolDeliveryDevice (INADD) employing an artist's airbrush as aerosolizer and precise, electromechanical control of spray duration. It was designed for the administration of controlled doses of nicotine in a laboratory setting and has been used successfully in over 30 smokers and nonsmokers of both genders.(More)
OBJECTIVE To evaluate the veterinary version of the bladder tumor antigen (V-BTA) test as a screening test for transitional cell carcinoma (TCC) of the lower urinary tract of dogs. ANIMALS 229 client-owned dogs. PROCEDURE Urine samples from dogs were shipped overnight to a single laboratory to facilitate testing within 48 hours of collection by use of(More)
Hypothesizing the existence of a subgroup of female smokers for whom nicotine masks, and abstinence unmasks, a tendency toward hyperphagia and perhaps even subthreshold disordered eating, we compared female "weight-control smokers" (WC; n = 46) and "non-weight-control smokers" (NWC; n = 52) on smoking- and eating-related variables. We also examined the(More)
OBJECTIVES To conduct a prospective evaluation to determine the utility of the BTA stat test in the detection of upper tract transitional cell carcinoma (UTTCC). Monitoring for UTTCC currently relies on invasive procedures such as upper tract imaging, ureteral washing cytology (UWC) and/or ureteroscopy, or voided urine cytology (VUC). The BTA stat test is a(More)
Conventional screening for circulating antinuclear antibodies (ANA) is generally performed by immunofluorescent (IF) microscopy with a 1:40 dilution of serum. Intensity of IF staining is then semiquantitated by using twofold serial dilutions, where the highest dilution in which staining intensity equals the endpoint control is expressed as an endpoint(More)
