Second-order auditory neurons in nucleus magnocellularis (NM) of the chick brainstem undergo a series of rapid metabolic changes following unilateral cochlea removal, culminating in the death of 25% of NM neurons. Within hours of cochlea removal, ipsilateral NM neurons show marked increases in histochemical staining for the mitochondrial enzymes succinate(More)
Changes in cytochrome oxidase (CO) activity were studied in the chick brainstem auditory nuclei, n. magnocellularis (NM) and n. laminaris (NL), following unilateral cochlea removal. Chickens aged 10 days or 56 weeks underwent unilateral cochlea removal. Following survival periods of 30 minutes to 14 days for the 10-day-old birds and 6 hours or 14 days for(More)

The role of mitochondrial biogenesis in hair cell survival after injury was evaluated by inhibiting mitochondrial protein synthesis with chloramphenicol and then studying the effects on hair cell survival after exposure to two different types of ototoxins, gentamicin and acoustic trauma. Seven- to 10-day-old chicks were treated with either a single(More)
large, intermediate, and small presses in the years 1980 through 1990, and posits various hypothesis to be borne out, or not, by the data. Once a section's conclusions are stated, Dr. Black commences another logical step in her argument in the following chapter. After overcoming the odds, breaking the " first seal " and being published, these works by(More)
the content will remain relevant as more and more information literacy instruction moves into those formats. Though much of the discussion is theoretical, numerous citations (many annotated) provide the instruction practitioner with an entry point into the intimidating literature on teaching theory and practice.—Timothy Imagine this scenario: you're an(More)
OBJECTIVE To examine a group of patients satisfying criteria for "frequent attending" as part of an audit of an outpatient gastroenterology service, and to note the prevalence of those with no conspicuous organic disease to account for their symptomatology. METHODS We used the hospital computer (Oxford Patient Administration System, OXPAS) to identify(More)
Technology archivist Helen Willa Samu-els published an article in American Archivist entitled " Who Controls the Past. " Invoking George Orwell's lines from 1984: " who controls the past, controls the future, " Samuels noted that in " a modern, complex, information-rich society… only a small portion of the vast documentation can be kept… archivists are(More)
