Pantothenate kinase (PanK) is a rate-determining enzyme in coenzyme A (CoA) biosynthesis. The mouse murine pantothenate kinase (Pank1) gene consists of seven introns and eight exons and is located on chromosome 19 (19C2-3). Two biochemically distinct PanK1 protein isoforms, PanK1 alpha and PanK1 beta, are encoded by the Pank1 gene. Both proteins have the(More)
Pantothenate kinase (PanK) is thought to catalyze the first rate-limiting step in CoA biosynthesis. The full-length cDNA encoding the human PanK1alpha protein was isolated, and the complete human PANK1 gene structure was determined. Bezafibrate (BF), a hypolipidemic drug and a peroxisome proliferator activator receptor-alpha (PPARalpha) agonist,(More)
Super-resolution enhancement is the technique of increasing spatial resolution of an image from the image itself or from several noisy images of the same scene but with additional information such as motion. This paper presents a kernel regression approach to reconstruct a high resolution image from several low resolution video frames. In many applications(More)
CTP:phosphocholine cytidylyltransferase (CCT) is a key regulatory enzyme in phosphatidylcholine (PtdCho) biosynthesis, and in mammals, there are two distinct genes that encode enzymes that catalyze this reaction. This work defines the structures of both the murine CCT genes (Pcyt1a and Pcyt1b) and identifies a new CCT protein, CCTbeta3, with a unique amino(More)
There are two mammalian genes that encode isoforms of CTP:phosphocholine cytidylyltransferase (CCT), a key rate-controlling step in membrane phospholipid biogenesis. Quantitative determination of the CCT transcripts reveals that CCTalpha is ubiquitously expressed and is found at the highest levels in the testis and lung, with lower levels in the liver and(More)
Approximate analytical expressions are derived for the mean gain and the excess noise factor of avalanche photodiodes including the effect of dead space. The analysis is based on undertaking a characteristic-equation approach to obtain an approximate analytical solution to the existing system of recurrence equations which characterize the statistics of the(More)
