Specific cytotoxic T-lymphocyte (CTL) responses to nucleocapsid of infectious bronchitis virus (IBV) were identified by using target cells infected with a Semliki Forest virus (SFV) vector. Effector cells for CTL assays were collected from chickens infected with the Gray strain of IBV or inoculated with a DNA plasmid encoding nucleocapsid proteins.(More)
OBJECTIVE To determine whether combined positron emission tomography and computed tomography (PET-CT) may be of value in deferring planned neck dissections for patients with advanced head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN Observational study of patients with de novo cervical > or =N2 regional spread of HNSCC in a tertiary care(More)
PURPOSE Robotic assisted laparoscopic extravesical ureteral reimplantation is becoming more widely used as an alternative to open reimplantation. To date, no direct comparison to the open approach in a similar cohort exists. We review a single surgeon experience and compare the outcomes of robotic assisted laparoscopic extravesical ureteral reimplantation(More)
This study represents the largest series to date documenting the gonadotoxic effect in humans of dibromochloropropane, a widely used pesticide. Three semen analyses, serum hormonal determinations (luteinizing hormone, follicle-stimulating hormone and testosterone) as well as genital examinations were completed for 228 workers at 2 chemical production sites(More)
Phase-matched difference-frequency mixing in a thin GaSe crystal within the broad spectrum of 25-fs pulses from a Ti:sapphire oscillator multipass amplifier system permits the generation of few-cycle electric field transients, frequencies up to 30 THz, and amplitudes of more than 1 MV/cm. The field transients generated at a 1-kHz repetition rate are(More)
BACKGROUND Although numerous reports have described interventions designed to influence antibiotic utilization, to our knowledge none have been evaluated in a randomized study. METHODS Adult inpatients receiving 1 or more of 10 designated parenteral antibiotics for 3 or more days during a 3-month period were randomized to an intervention (n = 141) and a(More)
PURPOSE We incorporated cetuximab, a chimeric monoclonal antibody against the epidermal growth factor receptor (EGFR), into the induction therapy and subsequent chemoradiotherapy of head and neck cancer (HNC). PATIENTS AND METHODS Patients with locally advanced HNC, including squamous and undifferentiated histologies, were treated with docetaxel 75 mg/m2(More)
Endothelial cell dysfunction is associated with cardiovascular disease and vasculogenic erectile dysfunction (ED). Measured via peripheral artery tonometry (PAT), endothelial dysfunction in the penis is an independent predictor of future cardiovascular events. The aim of the study was to determine whether measurement of endothelial dysfunction(More)
OBJECTIVE To review the role of hybrid positron emission tomography (PET)-computed tomography (CT) systems in the design and management of cancer patients in the modern radiation oncology practice. PET is co-registered with CT and incorporated into a systematic approach to the staging, management, and assessment of response and surveillance of a variety of(More)
Six hundred ninety-two women were enrolled in a multicenter clinical trial to evaluate a combination of ethinyl estradiol and dl-norgestrel as a postcoital contraceptive. When compared with various formulas predicting the probability of pregnancy in this group, the number of pregnancies observed appears to be reduced by approximately 84%. The combination of(More)
