Goose parvovirus (GPV) and avian influenza virus subtype H9N2 are single-stranded DNA (ssDNA) and single-stranded RNA (ssRNA) viruses, respectively, both of which can spread in goslings and cause a significant economic loss. To explore the comprehensive transcriptome of GPV- or H9N2-infected goose spleens and to understand the immune responses induced by a DNA virus (GPV) or a RNA virus (H9N2),...
Suggestive evidence for the extragonadal origin of germ cells in birds was first presented by Swift (1914), who described primordial germ cells in the chick embryo at as early a stage as the primitive streak. According to Swift, primordial germ cells are originally located extra-embryonically in the anterior part of the blastoderm and occupy a crescent-shaped region ('germinal crescent') on the...
Abstract Geese are one of the most important poultry around world. For origin geese, current generally accepted hypothesis is that European domestic geese were originated from greylag goose (Anser anser), and Chinese have two origins, breeds which swan cygnoides), Yili geese. In order to explain demographic history we selected 14 Europe China wild populations goose, whole genome resequencing da...
butyl ester), was done in the conventional way. Using this combination, [ ~ A l a ~ ~ ) IDHI was obtained in crystalline form and gave about 50% of the insulin activity in the mouseconvulsion assay. Insulins from different species are analogues formed in the course of evolution and are very useful in structure-and-function studies. We have worked out a simple method for isolating these analogue...
Scallop shell powder produced by calcination process - the average diameter of the powder particles being 20 µm (SSP) - was further ground into nano-sized particles, with average diameter of 500 nm, here designated CaO-Nano. Solution of CaO-Nano could inactivate avian influenza virus within 5 sec, whereas the solution of SSP could not even after 1 hr incubation. CaO-Nano solution could also ina...
