    Title Direct Electrical Stimulation of Heschl's Gyrus for Tinnitus Treatment.
    Date April 2008
    Journal The Laryngoscope

    OBJECTIVES/HYPOTHESIS: The purpose of the study was to determine the effect of electrical stimulation of the auditory cortex in patients with tinnitus. STUDY DESIGN: Nonrandomized clinical trial. METHODS: Two patients with debilitating tinnitus refractory to conventional therapies were treated. Patients were evaluated with validated questionnaires and psychoacoustic measures to determine the frequency and pitch of their tinnitus. Tones at these frequencies were then presented to the first patient (RP) under magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) to determine the tonotopic map for these frequencies in Heschl's gyrus. These tonotopic sites were targeted for implant with a quadripolar electrode. In the second patient (MV), only the fMRI tonotopic map was performed. These fMRI results detected an area of increased activity, which was selected as the site for the implanted bipolar electrode. RESULTS: Patient RP (bilateral tinnitus for 2 years) has experienced a sustained reduction to near elimination of tinnitus with intracerebral implanted electrodes, whereas patient MV (unilateral tinnitus for 7 years) had an unsustained reduction in her tinnitus. CONCLUSION: These findings suggest that the perception and annoyance of tinnitus may be modulated or reduced through electrical stimulation of the auditory cortex. These unsustained effects for patient MV may have been influenced by the longstanding nature of her tinnitus or by another reason as yet undetermined.

    Title Auditory Research Involving Antioxidants.
    Date December 2007
    Journal Current Opinion in Otolaryngology & Head and Neck Surgery

    PURPOSE OF REVIEW: The role of antioxidants in the management of hearing loss has generated considerable interest over the past several years. Research efforts in this field have yielded many new insights into the molecular and cellular nature of several types of hearing impairment, including age-related, noise-induced, and drug-induced hearing loss. The objective of this paper is to highlight some of the important studies published over the past several years that have further contributed to our understanding of the mechanism of antioxidants in attenuating hearing loss. RECENT FINDINGS: There is compelling evidence to suggest that antioxidant therapy is beneficial in attenuating, improving, or reversing the effects of several types of acquired hearing loss. Cellular and subcellular changes resulting from these types of hearing impairment are remarkably similar and seem to have a common putative mechanism of oxidative stress and damage. Recent studies have lent further credibility to the notion that antioxidant therapy can be of considerable benefit in the treatment of hearing loss. The increasing body of literature pertaining to human studies will shed further light into this fascinating area of research. SUMMARY: This review elucidates the role of antioxidants in hearing loss and illustrates the continued evolution of research efforts in this field.

    Title Co2 and Fluorinated Solvent-based Technologies for Protein Microparticle Precipitation from Aqueous Solutions.
    Date March 2004
    Journal Biotechnology Progress

    Precipitation with a compressed or supercritical fluid antisolvent (PCA) has been used to produce microparticles of biologically active proteins, pharmaceuticals, and polymers. However, the application of PCA to a wider range of proteins is limited by the low mutual solubility of water (necessary to dissolve most proteins) and CO(2) (traditionally used as the compressed antisolvent). This investigation extends PCA to proteins in aqueous solutions by utilizing ethanol as a cosolvent to enhance the antisolvent properties of CO(2) toward aqueous systems. alpha-Chymotrypsin, a model protein, was precipitated from both compressed CO(2) and a liquid fluorinated antisolvent, a hydrofluoroether (HFE). The equilibrium phase behavior of the antisolvent/ethanol/water systems was examined to identify a one-phase region suitable for protein precipitation. Spherical protein microparticles with a primary particle size of approximately 0.2-0.6 microm were recovered using both the compressed CO(2) and fluorinated antisolvents. Although the proteins retained significant activity using both antisolvent systems, the HFE-precipitated chymotrypsin retained higher activity than the CO(2)-precipitated protein.
