THE retina in birds projects to the contralateral tectum. Our previous study and some otherphysiological, histochetnical and neurochemical evidence have suggested that the retino-tectal projection in birds might use glutamate as an excitatory transmitter. However, very lit-tle is known about its particular receptor type(s), because there are at least three major phar-macologically defined types of glutamate receptors: NMDA, AMPA/Kainate, andmetabotropic glutamate receptors.

NGUYEN et al. give a method for constructing binary CP constant-weight (CPC) codes,then they construct protocol sequences with good performance by using the codes. To makethe minimum distance of the CP codes large enough, Nguyen et al. select two classes of maxi-mum distance separable(MDS) codes which are q-ary Reed-Solomon (R-S) codes and q-arygeneralized Berlekamp-Justesen(B-J) codes.

作者： Chun-Ming Liu ph.D. Editor-in-Chief

From Executive Editor to Editor-in-Chief is a big jump for me, and means many more responsibilities. I could feel the pressure on my shoulders; from the hopes of my predecessors, my colleagues, and the board members. As a journal with a 57-year history, JIPB has built its credit over the years, publishing many original works in both Chinese and English. However, in the international scientific community, JIPB is still a minor player, especially under the current not-so-healthy impact factor-driven publishing environment.

Canada’s Inter-agency Wild Bird Influenza Survey,which started in 2005,and is a collaborative effort among federal,provincial and territorial government agencies as well as non-governmental organizations and academic institutions,has two components:(i)a seasonal survey of live wild waterfowl species from selected geographic regions across Canada(to expand our understanding of the avian influenza viruses circulating in wild bird populations);and(ii)an ongoing survey of birds found dead that are submitted to a regional diagnostic laboratory(to enhance detection of highly pathogenic avian influenza strains).Combined swabs from the cloaca and oro-pharynx collected from each bird are screened using a real-time reverse transcriptase-polymerase chain reaction(RRT-PCR)that targets a unique segment of the influenza A M1 *** the M1 result is positive or inconclusive,RRT-PCR for gene segments of the H5 and H7 hemagglutinin subtypes are *** samples that are RRT-PCR positive for H5 or H7 are sent immediately for test confirmation and further *** field and laboratory data are entered into a database developed and maintained by the Canadian Cooperative Wildlife Health *** the survey commenced in 2005,on average,30%of all live ducks sampled,5%of other species of live birds and 3%of birds found dead have tested positive for avian influenza,all of North American lineage and of low pathogenicity.
