Rats treated chronically with diazepam develop tolerance to diazepam effects and show changes in sensitivity of GABAergic systems. In order to investigate possible molecular mechanisms associated with these changes, we have evaluated the effects of acute and chronic diazepam treatment on levels of mRNA for the alpha 1 and beta 1 subunits of the GABAA(More)
The Telephone Counseling Trial for Breast Cancer Survivors is a randomized, controlled study designed to test the impact of a telephone-based counseling intervention on quality of life of early-stage breast cancer patients who have completed adjuvant treatment. A psychoeducational counseling model is utilized to promote adaptive coping to re-entry stressors(More)
A 1.8-kilobase (kb) cDNA clone for a beta 1 subunit of the human gamma-aminobutyric acidA (GABAA) receptor has been isolated and sequenced. The longest open reading frame of the clone, pCLL610, contains nucleotide sequence encoding a portion of the putative signal sequence followed by 449 amino acids of the entire mature protein. The deduced amino acid(More)
Using a new, double-sided adhesive process, an analog tunable capacitor has been designed and fabricated with an extremely large tuning range and a high Q. New design components such as two-sided metal deposition, low resistivity silicon, thicker device layers, and double beam suspensions have improved RF performance drastically. In the 200-400 MHz range(More)
OBJECTIVE To determine whether a telephone counseling program can improve psychosocial outcomes among breast cancer patients post-treatment. METHODS A randomized trial was conducted involving 21 hospitals and medical centers, with assessments (self-administered questionnaires) at baseline, 12 and 18 months post-enrollment. Eligibility criteria included(More)
BACKGROUND Individuals with a strong family history of colorectal cancer have significant risk for colorectal cancer, although adherence to colonoscopy screening in these groups remains low. This study assessed whether a tailored telephone counseling intervention can increase adherence to colonoscopy in members of high-risk families in a randomized,(More)
The binding of t-[35S]butylbicyclophosphorothionate [( 35S]TBPS) to a site on the GABAA receptor complex is ion dependent. This study was conducted to determine the effects of ion species and concentration on the time course, affinity, and number of sites of [35S]TBPS binding. At a concentration of 200 mM ion, the time to equilibrium for [35S]TBPS binding(More)
The ability of a selective 5-hydroxytryptamine (5-HT(3)) receptor antagonist, ICS 205-930 (3-tropanyl-indole-1-carboxylate, tropisetron), to block the discriminative stimulus effects of ethanol was investigated in rats that were trained to discriminate ethanol (1.25 g/kg ip) from saline with food as the reinforcement. Prior administration of ICS 205-930, at(More)
The ability of a selective 2-opiate receptor antagonist, naltriben, to modulate ethanol discrimination was investigated in a rat model using a drug discrimination procedure. Rats were trained to discriminate ethanol (1.25 g/kg, IP) from saline on a fixed-ratio schedule, FR10. Once rats had acquired the ethanol-saline discrimination, ethanol dose-response(More)
t-[35S]Butylbicyclophosphorothionate [( 35S]TBPS) has been shown to bind to the GABAA receptor complex. The binding is modulated allosterically by drugs that interact at components of the receptor complex. The present studies were designed to evaluate the influence of ionic environment and state of equilibrium on the allosteric modification of [35S]TBPS(More)
