We report here a simple and effective method to assess the CAG repeat size of HD gene for gene diagnosis of Huntington disease,Genomic DNA sequences in polymorphic CAG repeat HD gene was amplified by PCR with TaKaRa LA Taq DNA polymerase and GC buffer.

Sense and anti-sense transgenic alfalfa plants(F4 and D3) were used to investigate the biological functions of the HD-Zip transcription factor gene Mfhb-1 via direct somatic embryogenesis system in alfalfa.

In this paper, the situation of research about HD-Zip proteins in Arabidopsis thaliana was focused and supplemented with other plants, four parts of main studying points were summerized, which include the kind of HD-Zip transcription factor, biological functions and the pattern of gene expression.

Aortic rings were subjected to contractile concentration responses to NE followed by relaxation to insulin(120 U/L),with and without preincubation for 15 minute with L-NAME or 5-Hydroxydecanoate(5-HD).

The optimizing analyses of cushion layer are carried out by two FEM models of spiral case structure in hydropower station with different HD values.

With the HD value of hydropower station hightening sharply,the design optimum and structure safety seem more important.
