We introduce a novel algorithm to reconstruct dynamic magnetic resonance imaging (MRI) data from under-sampled k-t space data. In contrast to classical model based cine MRI schemes that rely on the sparsity or banded structure in Fourier space, we use the compact representation of the data in the Karhunen Louve transform (KLT) domain to exploit the(More)
Yeast genetics and in vitro biochemical analysis have identified numerous genes involved in protein secretion. As compared with yeast, however, the metazoan secretory pathway is more complex and many mechanisms that regulate organization of the Golgi apparatus remain poorly characterized. We performed a genome-wide RNA-mediated interference screen in a(More)
Nicastrin is genetically linked to Notch/lin-12 signaling in C. elegans and is part of a large multiprotein complex along with Presenilin. Here we describe the isolation and characterization of Drosophila Nicastrin (Nic) mutants. Nic mutants and tissue clones display characteristic Notch-like phenotypes. Genetic and inhibitor studies indicate a function for(More)
Clonorchis sinensis is a carcinogenic human liver fluke that is widespread in Asian countries. Increasing infection rates of this neglected tropical disease are leading to negative economic and public health consequences in affected regions. Experimental and epidemiological studies have shown a strong association between the incidence of cholangiocarcinoma(More)
Internet clouds work as service factories built around web-scale datacenters. The elastic cloud resources and huge datasets processed are subject to security breaches, privacy abuses, and copyright violations. Provisioned cloud resources on-demand are especially vulnerable to cyber attacks. The cloud platforms built by Google, IBM, and Amazon all reveal(More)
Breast cancer has never had any good serum tumor markers. Therefore, we developed and evaluated a proteomics approach to searching for new biomarkers and building diagnostic models. SELDI-TOF-MS ProteinChip was used to detect the serum protein patterns of 49 breast cancer patients, 51 patients with benign breast diseases, and 33 healthy women. The(More)
BACKGROUND Propofol exposure to neurons during synaptogenesis results in apoptosis, leading to cognitive dysfunction in adulthood. Previous work from our laboratory showed that isoflurane neurotoxicity occurs through p75 neurotrophin receptor (p75(NTR)) and subsequent cytoskeleton depolymerization. Given that isoflurane and propofol both suppress neuronal(More)
The gamma-secretase complex is required for intramembrane cleavage of several integral membrane proteins, including the Notch receptor, where it generates an active signaling fragment. Four putative gamma-secretase components have been identified-presenilin (Psn), nicastrin (Nct), Aph-1, and Pen-2. Here, we use a stepwise coexpression approach to(More)
Clonorchis sinensis (C. sinensis), an important food-borne parasite that inhabits the intrahepatic bile duct and causes clonorchiasis, is of interest to both the public health field and the scientific research community. To learn more about the migration, parasitism and pathogenesis of C. sinensis at the molecular level, the present study developed an(More)
N-Methyl-D-aspartate (NMDA) receptor (NMDAR) activation and downstream signaling are important for neuronal function. Activation of prosurvival Src family kinases and extracellular signal-regulated kinase (ERK) 1/2 is initiated by NMDAR activation, but the cellular organization of these kinases in relation to NMDARs is not entirely clear. We hypothesized(More)
