Auditory brainstem responses (ABRs) and otoacoustic emissions (OAEs) are objective measures of auditory function, but are not hearing tests. Normal OAEs reflect normal cochlear outer hair cell function, and an ABR indicates a synchronous neural response. It is quite possible for a patient to have normal OAEs but absent or grossly abnormal ABR and a(More)
Function of the olivocochlear reflex, measured by suppression of transient evoked otoacoustic emissions, is assessed in nine patients with bilateral auditory neuropathy/dys-synchrony and compared to matched control subjects with normal auditory function. TEOAEs were acquired using 65 dB peak sound pressure linear clicks with and without the presence of(More)
OBJECTIVE The aim of this study was to examine the relationship between current active attention-deficit/hyperactivity disorder (ADHD) symptoms, medication treatment, and substance use patterns among college students. METHOD Three hundred and thirty-four students at a local college were surveyed for current ADHD symptoms and psychopharmacological(More)
GyrATPase is a cellular enzyme that has been used as an antibacterial target for treatment of nosocomial and community acquired bacterial infections. The leading chemical series targeted at inhibiting this enzyme, indazoles, were rapidly cleared in rats (CL > 70 mL/min/kg). The predominant metabolite identified in both urine and bile samples from a bile(More)
Bacterial resistance to antibiotic therapy remains a worldwide problem. In Pseudomonasaeruginosa, rates of efflux confer inherent resistance to many antimicrobial agents, including fluoroquinolones, due to a high level of expression and a relatively high turnover number of the efflux pumps in gram-negative bacteria. To understand the roles of efflux pumps(More)
INTRODUCTION Few studies have rigorously evaluated the effectiveness of health-related continuing education using satellite distribution. This study assessed participants' professional characteristics and their changes in knowledge, attitudes, and actions taken after viewing a public health preparedness training course on mass vaccination broadcast(More)
In February 2007, the U.S. Department of Energy, BP Exploration (Alaska), and the U.S. Geological Survey, collected the first open-hole formation pressure response data in a gas hydrate reservoir (the “Mount Elbert” stratigraphic test well) using Schlumberger’s Modular Dynamics Formation Tester (MDT) wireline tool. As part of an ongoing effort to compare(More)
This collaborative effort to compare the world’s leading gas hydrate reservoir simulators is designed primarily to exchange information and insight that will lead to the improvement in simulation capability of experimental and naturally occurring gas hydrate accumulations. The initial phase of the code comparison activity achieved the simulation of five(More)
In the late spring of 2008, the Chevron-led Gulf of Mexico Gas Hydrate Joint Industry Project (JIP) expects to conduct an exploratory drilling and logging campaign to better understand gas hydrate-bearing sands in the deepwater Gulf of Mexico. The JIP Site Selection team selected three areas to test alternative geological models and geophysical(More)
Total organic carbon (TOC) content of marine sediments represents residual carbon, originally derived from terrestrial and marine sources, which has survived seafloor and shallow subseafloor diagenesis. Ultimately, its preservation below the sulfate reduction zone in marine sediments drives methanogenesis. Within the gas hydrate stability zone (GHSZ),(More)
