To understand the development of serotonergic neurons in vertebrates, we used zebrafish as a model system. In this study we cloned two cDNAs (complementary DNAs) coding for serotonin transporter (SERT) from the zebrafish, named serta and sertb. The serta cDNA encodes a protein of 693 amino acids and showed high level of sequence identity with rat and human(More)
The relative importance of north-south migrations of the intertropical convergence zone (ITCZ) versus El Niño-Southern Oscillation and its associated Pacific Walker Circulation (PWC) variability for past hydrological change in the western tropical Pacific is unclear. Here we show that north-south ITCZ migration was not the only mechanism of tropical Pacific(More)
In the program ODS_BOOTSTRAP we provide a methodology for quickly ordering clones in a genomic library into a physical map and for applying a statistical tool known as the bootstrap to assess the statistical reliability of a clonal ordering. Each clone is assigned a binary fingerprint by one of a variety of experimental approaches to physical mapping. For(More)
An automatic threshold selection method is proposed for biomedical image analysis based on a histogram coding scheme. We show that the threshold values can be determined based on the well-known Lloyd-Max scalar quantization rule, which is optimal in the sense of achieving minimum mean square error distortion. We derive an iterative self-organizing learning(More)
BACKGROUND AND PURPOSE In a rat model of middle cerebral artery occlusion (MCAO) with intraluminal technique, lesion volume and its reproducibility vary among laboratories. Although laser-Doppler flowmetry (LDF) is useful to optimize the reliability, conventional methods require a craniotomy and special apparatus. The purpose of this study was to evaluate a(More)
Klotho is a new anti-aging gene. Genetic mutation of klotho causes multiple premature aging-like phenotypes and strikingly shortens lifespan. Overexpression of the klotho gene in mice suppresses aging and extends lifespan which may involve the mechanism of suppression of insulin signaling and oxidant stress. Klotho functions as a cofactor/coreceptor(More)
A Zero Overhead Loop Buffer (ZOLB) is an architectural feature that is commonly found in DSP processors. This buffer can be viewed as a compiler managed cache that contains a sequence of instructions that will be executed a specified number of times. Unlike techniques such as loop unrolling, a loop buffer is a hardware technique that can be used to minimize(More)
Schistosomiasis is a tropical disease associated with high morbidity and mortality, currently affecting over 200 million people worldwide. Praziquantel is the only drug used to treat the disease, and with its increased use the probability of developing drug resistance has grown significantly. The Schistosoma parasites can survive for up to decades in the(More)
SUMMARY We have created a set of applications using Perl and Java in combination with XML technology to install biological sequence databases into an Oracle RDBMS. An easy-to-use interface using Java has been created for database query and other tools developed to integrate with our in-house bioinformatics applications. AVAILIBILITY: The database schema,(More)
We describe a novel algorithm, Grid algorithm, and the corresponding computer program for high throughput fitting of dose-response curves that are described by the four-parameter symmetric logistic dose-response model. The Grid algorithm searches through all points in a grid of four dimensions (parameters) and finds the optimum one that corresponds to the(More)
