The microstructure and texture evolution of pure nickel sheets during cryorolling and subsequent short-time low-temperature annealing were analyzed by electron backscatter diffraction technique. Results show that the content of typical texture of brass, copper, S, cube, and Goss texture is no significant change during cryorolling with a reduction of 40%. When the reduction reaches 60%, it begins to significantly increase, and when the reduction reaches 80%, it exhibits a copper type texture. However, when the reduction is 20%, the fiber texture of <110>//normal direction (ND) orientation begins to significantly increase, which was mainly caused by dislocation slip during cryorolling. During low temperature and short time annealing, the content of typical textures decreases except S texture, and the grain changes mainly occur in grains other than <110>//ND orientation which is due to the rich substructure and high dislocation density formed in the cryorolling process leading to rapid response to annealing.

AbstractBackground: Adiponectin(ADP) polymorphisms associated with diabetes mellitus in several populations. However, no previous studies have investigated its association with diabetic peripheral neuropathy (DPN). Our study examined the association between ADP-linked SNPs and DPN susceptibility.Methods: We randomly recruited 160 diabetes mellitus (DM) patients and 80 healthy individuals.Results: The C allele of rs3821799 increased DPN susceptibility. In normal individuals, GG of rs3774261 carriers had 7.1 times higher DPN susceptibility than AA carriers. The haplotype analyzes indicated CGG might increase DPN susceptibility.Conclusion: Our study demonstrated that ADPgene polymorphisms are associated with the susceptibility to DPN.

G ABA (gamma-aminobutyric acid), as the main inhibitory neurotransmitter in the brain, plays an essential role for the overall balance between neuronal excitation and inhibition by acting on GABAA receptors, which are ligand-gated chloride channels. Impaired GABAergic function contributes to certain forms of epilepsy, schizophrenia, Alzheimer's Disease, and other neurological disorders. In order to identify possible genetic features and to further study biological regulation of GABAA receptor genes whose promoter elements and sequence anomalies may contribute to epileptic disorders, as an initial step, we shot-gun sequenced a BAC clone, dj082c10 (195,909-bp in size), encompassing human γ2 subunit of GABAA receptor (GABRG2). It is, we believe, the first genomic sequence of the GABA receptor gamma subunit family. Four contigs were assembled from 2950 reads prior to gap in an average redundancy of eight folds over the entire region. The precision of the consensus sequence was predicted to be 99.999% after closing gaps and finishing weak regions. The nine exons of GABRG2 spans an 85-kb region that had 81 SINEs comprising 22.32%, and nine LI elements comprising 3.40%, respectively. However, the density of L1 in the regions flanking GABRG2 gene (29.45% by 45 elements) is significantly higher than that within the gene. The length of GABRG2 introns varies in the range of 1.5 kb to 38.1 kb.
