Wingless (Wg) is an important signaling molecule in the development of Drosophila, but little is known about its signal transduction pathway. Genetic evidence indicates that another segment polarity gene, dishevelled (dsh) is required for Wg signaling. We have recently developed a cell culture system for Wg protein activity, and using this in vitro system as well as intact Drosophila embryos, w...

The patterning of the Drosophila mesoderm requires Wingless (Wg), one of the founding members of a large family of secreted glycoproteins, the Wnt family. Little is known about how Wg provides patterning information to the mesoderm, which is neither an epithelium nor contains the site of Wg production. By studying specification of muscle founder cells as marked by the lineage-specific transcrip...

Welch–Gong (WG) transformation sequences are binary sequences of period 2 1 with two-level autocorrelation. These sequences were discovered by Golomb, Gong, and Gaal in 1998 and they verified the validity of their construction for 5 20. Later, No, Chung, and Yun found another way to construct the WG sequences and verified their result for 5 23. Dillon first proved this result for odd in 1998, a...

Welch-Gong (WG) transformation sequences are binary sequences of period 2 − 1 with 2-level auto correlation. These sequences were discovered by Golomb, Gong and Gaal in 1998 and verified for 5 ≤ n ≤ 20. Later on, No, Chung and Yun found another way to construct the WG sequences and verified their result for 5 ≤ n ≤ 23. Dillon first proved this result for odd n in 1998, and finally, Dobbertin an...

Pseudorandom number generators play an important role to provide security and privacy on radio frequency identification (RFID) tags. In particular, the EPC Class 1 Generation 2 (EPC C1 Gen2) standard uses a pseudorandom number generator in the tag identification protocol. In this paper, we first present a pseudorandom number generator, named the filtering nonlinear feedback shift register using...

Three experiments were conducted to determine the nutritional value of wheat gluten (WG) for weanling pigs. In Exp. 1, 72 pigs (4.2 kg average BW) were used in a N metabolism experiment. Treatments were 1) casein-corn-based control; 2, 3, 4, 5, and 6) Diet 1 with flash-dried WG, spray-dried WG, two enzyme-modified (to increase solubility) WG, and soybean meal (SBM) used to replace casein, respe...

BACKGROUND Lack of CD28 expression on peripheral blood CD4+ and CD8+ T cells has been reported in patients with Wegener's granulomatosis (WG), suggesting a pathogenetic role of CD28- T cells in WG. METHODS Ten patients with WG and six with sarcoidosis (disease control) were analysed. Fluorescence activated cell sorter (FACS) analysis was used to detect CD28 expression on T cells from peripher...

Ž . Apparent digestibility coefficients ADCs of macronutrients and energy, and apparent absorpŽ . tion coefficients AACs of amino acids and elements were assessed in an experiment with 0.9 kg Atlantic salmon reared in saltwater tanks. Duplicate groups of fish were fed five diets, where 0, Ž . Ž . 6.25, 12.5, 25 and 50% of crude protein CP from fish meal FM was replaced with CP from Ž . wheat gl...

Tissue growth during animal development depends on the coordination of cell proliferation and cell death. The EGF-receptor/MAPK, Hedgehog, Dpp, Wingless (Wg) and Notch signaling pathways have been implicated in growth control in the developing Drosophila wing. In this report, we examine the effects of Notch and Wg on growth in terms of cell proliferation and cell survival. Reduction of Wg signa...

Recent studies in Drosophila have shown that heparan sulfate proteoglycans (HSPGs) are required for Wingless (Wg/Wnt) signaling. In addition, genetic and phenotypic analyses have implicated the glypican gene dally in this process. Here, we report the identification of another Drosophila glypican gene, dally-like (dly) and show that it is also involved in Wg signaling. Inhibition of dly gene act...
