Silencing and variegated transgene expression are poorly understood problems that can interfere with gene function studies in human embryonic stem cells (hESCs). We show that transgene expression (enhanced green fluorescent protein [EGFP]) from random integration sites in hESCs is affected by variegation and silencing, with only half of hESCs expressing the(More)
BACKGROUND The last 10 years have seen growing recognition of the significance of the genes encoding enzymes responsible for hepatic alcohol metabolism as protective factors in the development of alcoholism. METHODS We have developed DNA sequencing assays for measuring genetic variation at the alcohol dehydrogenase 2 (ADH2), ADH3, and aldehyde(More)
Background: Primary squamous cell carcinoma of the parotid is an uncommon, aggressive malignancy with a poor prognosis. The diagnosis is made after excluding metastasis from other sites in the head and neck or other primary malignancies of the parotid. Methods: Tumor registry data from 1974 to 1994 were reviewed at three University of Louisville- affiliated(More)
Stroke-prone rat strains exhibit an increased stroke risk and sensitivity, and reduced endogenous mechanisms of ischemic brain tolerance. This experiment provides a comparative, serial evaluation of neurological deficits and brain injury following middle cerebral artery occlusion/permanent focal stroke in this high-risk strain. Stroke-prone spontaneously(More)
Coccidioides spp. are saprophytic, dimorphic fungi that are endemic to arid climates, are capable of infecting many species, and result in diverse clinical presentations. An indoor-housed laboratory rhesus macaque presented with weight loss and decreased activity and appetite. During the diagnostic evaluation, a bronchiolar-alveolar pattern in the cranial(More)
Alterations in neutrophil extravasation are seen in disease states and in response to therapeutics. To investigate neutrophil extravasation during the acute inflammatory response, a skin-window technique used in humans was adapted for use in cynomolgus macaques (Macaca fasicularis). Modulation of neutrophil extravasation was attempted with systemic(More)
