A semiautomatic algorithm for segmenting organ surfaces from 3D medical images is presented in this work. The algorithm is based on a deformable model, and allows the user to initialize the model by combining and molding primitive shapes such as cylinders and spheres to form an initial approximate model of the organ surface. The initial model is(More)
Over 28,000 expressed sequence tags (ESTs) were produced from cDNA libraries representing a variety of growth conditions and cell types. Several Magnaporthe grisea strains were used to produce the libraries, including a nonpathogenic strain bearing a mutation in the PMK1 mitogen-activated protein kinase. Approximately 23,000 of the ESTs could be clustered(More)
Piscidins, important components of the innate (nonspecific) immunity system in fish, have potent, broad-spectrum antimicrobial and antiparasitic activities. In this study, we reported a novel antimicrobial cationic peptide from Pseudosciaena crocea. Although this peptide exhibited a genomic (3 exons and 2 introns) and propeptide (signal peptide, mature(More)
BACKGROUND Chemokines and their receptors play important roles in host defense, organogenesis, hematopoiesis, and neuronal communication. Forty-two chemokines and 19 cognate receptors have been found in the human genome. Prior to this report, only 11 chicken chemokines and 7 receptors had been reported. The objectives of this study were to systematically(More)
In this work, we determined the minimum number of detectable 111In-tropolone-labelled bone-marrow-derived stem cells from the maximum activity per cell which did not affect viability, proliferation and differentiation, and the minimum detectable activity (MDA) of 111In by SPECT. Canine bone marrow mesenchymal cells were isolated, cultured and expanded. A(More)
A novel Ebola virus (EBOV) first identified in March 2014 has infected more than 25,000 people in West Africa, resulting in more than 10,000 deaths. Preliminary analyses of genome sequences of 81 EBOV collected from March to June 2014 from Guinea and Sierra Leone suggest that the 2014 EBOV originated from an independent transmission event from its natural(More)
The expression of phosphorylated extracellular signal-regulated kinase 1/2 (pERK 1/2) was evaluated in the vestibular nuclei (VN) of rats following unilateral labyrinthectomy (UL). Immunohistochemistry revealed a significant asymmetrical increase in pERK 1/2 expression in the VN, 5 min after UL, after which pERK 1/2 immunoreactivity decreased rapidly and(More)
Deletion of the spermidine synthase gene in the fungus Aspergillus nidulans results in a strain, deltaspdA, which requires spermidine for growth and accumulates putrescine as the sole polyamine. Vegetative growth but not sporulation or sterigmatocystin production is observed when deltaspdA is grown on media supplemented with 0.05-0.10 mM exogenous(More)
The mechanisms by which sister chromatids maintain biorientation on the metaphase spindle are critical to the fidelity of chromosome segregation. Active force interplay exists between predominantly extensional microtubule-based spindle forces and restoring forces from chromatin. These forces regulate tension at the kinetochore that silences the spindle(More)
Forward genetic analysis is the most broadly applicable approach to discern gene functions. However, for some organisms like the filamentous ascomycete Neurospora crassa, genetic mapping frequently represents a limiting step in forward genetic approaches. We describe an efficient method for genetic mapping in N. crassa that makes use of a modified bulked(More)
