CTP:phosphocholine cytidylyltransferase (EC is a key regulatory enzyme in the synthesis of phosphatidylcholine in higher eukaryotes. This enzyme can interconvert between an inactive cytosolic form and an active membrane-bound form. To unravel the structure of the transferase and the mechanism of its interaction with membranes, we have cloned a(More)
OBJECTIVE To study the effect of the innate cytokine macrophage migration inhibitory factor (MIF) on the susceptibility and severity of systemic lupus erythematosus (SLE) in a multinational population of 1,369 Caucasian and African American patients. METHODS Two functional polymorphisms in the MIF gene, a -794 CATT(5-8) microsatellite repeat (rs5844572)(More)
Human CTP:phosphocholine cytidylyltransferase (CT) cDNAs were isolated by PCR amplification of a human erythroleukemic K562 cell library. Initially two degenerate oligonucleotide primers derived from the sequence of the rat liver CT cDNA were used to amplify a centrally located 230 bp fragment. Subsequently overlapping 5' and 3' fragments were amplified,(More)
BACKGROUND The clinical use of molecular diagnostics, genomics, and personalized medicine is increasing and improving rapidly over time. However, medical education incorporating the practical application of these techniques is lagging behind. Although instruction in these areas should be expanded upon and improved at all levels of training, residency(More)
Primary cutaneous amyloidosis describes a group of disorders in which amyloid is deposited in the skin without evidence of systemic involvement. Nodular localized primary cutaneous amyloidosis (NLPCA) is a rare form of these skin-restricted amyloidoses. We present an unusual case of NLPCA in a 51-year-old man, who had clinical and histopathological evidence(More)
Several ethical concerns are central to the field of medical research. A sampling of these ethical conundrums include fraudulent data, publication bias, conflict of interest, IRB compliance, and confidentiality. In this article we attempt to highlight some of the components central to these areas of concern. In doing so we hope to generate discussion(More)
Malignant melanoma can affect patients of any age. It has been well documented that the overall incidence of melanoma has increased in the past several decades, and this increase extends to the pediatric population (both preadolescent and, to a greater extent, adolescent children). Melanoma in adolescents, commonly defined as patients 11 to 19 years of age,(More)
BACKGROUND Several technologies have been developed to aid dermatologists in the detection of melanoma in vivo including dermoscopy, multispectral digital skin lesion analysis (MDSLA), and reflectance confocal microscopy (RCM). To our knowledge, there have been no studies directly comparing MDSLA and RCM. OBJECTIVE We conducted a repeated measures(More)
