In this study we report the molecular genetic characterization of the Arabidopsis mitochondrial phosphopantetheinyl transferase (mtPPT), which catalyzes the phosphopantetheinylation and thus activation of mitochondrial acyl carrier protein (mtACP) of mitochondrial fatty acid synthase (mtFAS). This catalytic capability of the purified mtPPT protein (encoded… (More)
Gadolinium-DTPA was used in MR imaging of the spine to determine the ability of a contrast agent to increase the detection and characterization of disease in the intradural extramedullary space. Although MR imaging, especially with recent technological improvements, has been shown to be at least competitive with, and often superior to, myelography and… (More)
Hearing screening is well established in most developed countries, and the data extensively published. However, little information has been presented by the developing, nonwhite populations. A screening study was carried out on 2202 Jamaican children aged 5 to 7 years. This involved tympanometry and pure-tone audiometry (frequencies of 0.5, 1, and 2 kHz.)… (More)
Osteomas are common in otolaryngology, as they often involve the skull and facial bones. On rare occasions, these tumors have also been found in the temporal bone and the tongue. Until now, osteomas have not been encountered in the larynx. We describe the case of a patient who came to our institution with hoarseness and dysphagia and who was found to have… (More)
A study of the clinical course of 20 patients with uveitis treated with transfer factor is reported. Twelve (60%) of the patients were initially immunoincompetent on screening. Eight of the 12 changed to an immunocompetent status after treatment and could either decrease or discontinue their anti-inflammatory drugs. Five had a statistically significant… (More)
NO plays diverse roles in physiological and pathological processes, occasionally resulting in opposing effects, particularly in cells subjected to oxidative stress. NO mostly protects eukaryotes against oxidative injury, but was demonstrated to kill prokaryotes synergistically with H2O2. This could be a promising therapeutic avenue. However, recent… (More)
A case of extramedullary plasmacytoma of the larynx is presented. The case is unique for the extramedullary plasmacytoma's marked extension into the mediastinum. The computed tomography (CT) features are described.
