Diaporthales represents an important order in Sordariomycetes containing taxa that are mainly isolated as endophytes, saprobes or plant pathogens on various hosts. The primary aim of the present study was to redefine the taxonomy and phylogeny of a large collection of Diaporthales species associated with diverse hosts in *** the current study, 12 families are involved here. cytosporaceae and Diaporthaceae are most common phytopathogenic taxa causing canker. Other nine different families associated with canker and dieback of tree hosts are morphologically treated and phylogenetically compared. These include cryphonectriaceae,Gnomoniaceae, melanconidaceae, melanocniellaceae and Juglanconidaceae. Four new families（Diaporthosporellaceae, Diaporthostomataceae, Pseudomelanconidaceae, Synnemasporellaceae）, and one new genus, Dendrostoma（Erythrogloeaceae） were introduced. We also summarized 51 cytospora and 15 Diaporthe species in china. The cytospora study emphasized on 39 species from 85 isolates representing 28 host genera based on combination of morphology and six locus phylogeny（ITS, LSU, act, rpb2, tef1-α and tub2）. Of which14 new species and one new combination are introduced with notes on their taxonomy and phylogeny. cytospora was investigated as wide distributions in northeast, northwest, north and southwest china, indicating the cold and dry environments are always favourable for these pathogenic fungi. The Diaporthe study emphasized on 15 species from 42 representative isolates involving 16 host genera using comparisons of six locus phylogeny（ITS,cal, his, tef1-α and tub2）. For the most part Diaporthales species appear to be host specific in china, although the majority of the species treated are known only from a few isolates, and further collections and pathogenicity studies will be required to reconfirm this conclusion.

Enhancing m^(6)A modification in the motor cortex facilitates corticospinal tract remodeling after spinal cord injury

Neural Regeneration Research 2025年第6期20卷 1749-1763页

作者： tian Qin Yuxin Jin Yiming Qin Feifei Yuan Hongbin Lu Jianzhong Hu Yong cao chengjun Li Department of Spine Surgery and Orthopedics Xiangya HospitalCentral South UniversityChangshaHunan ProvinceChina Key Laboratory of Organ Injury Aging and Regenerative Medicine of Hunan ProvinceChangshaHunan ProvinceChina National clinical Research center for Geriatric Disorders Xiangya HospitalCentral South UniversityChangshaHunan ProvinceChina Department of Sports medicine Xiangya HospitalCentral South UniversityChangshaHunan ProvinceChina

Spinal cord injury typically causes corticospinal tract disruption. Although the disrupted corticospinal tract can self-regenerate to a certain degree, the underlying mechanism of this process is still unclear. N6-methyladenosine(m^(6)A) modifications are the most common form of epigenetic regulation at the RNA level and play an essential role in biological processes. However, whether m^(6)A modifications participate in corticospinal tract regeneration after spinal cord injury remains unknown. We found that expression of methyltransferase 14 protein(mETTL14) in the locomotor cortex was high after spinal cord injury and accompanied by elevated m^(6)A levels. Knockdown of mettl14 in the locomotor cortex was not favorable for corticospinal tract regeneration and neurological recovery after spinal cord injury. Through bioinformatics analysis and methylated RNA immunoprecipitation-quantitative polymerase chain reaction, we found that mETTL14 regulated Trib2 expression in an m^(6)A-regulated manner, thereby activating the mitogen-activated protein kinase pathway and promoting corticospinal tract regeneration. Finally, we administered syringin, a stabilizer of mETTL14, using molecular docking. Results confirmed that syringin can promote corticospinal tract regeneration and facilitate neurological recovery by stabilizing mETTL14. Findings from this study reveal that m^(6)A modification is involved in the regulation of corticospinal tract regeneration after spinal cord injury.

Acta metallurgica Sinica(English Letters) 2003年第3期16卷 155-160页

Transmission electron microscopy (TEm) observations were carried out for examining the precipitation behavior in a cu-Sn-Ni-Zn-P lead frame material. TEm observations revealed that the precipitate is hexagonal Ni5P2 and the orientation relationship between the cu matrix and Ni$Pi precipitate is (111)fcc//(0001)hcp, [101]fcc//[1120]hcp, where the suffix fcc denotes the cu matrix and hep denotes the hexagonal Ni5P2 precipitate. The Ni5P2 precipitate is ovoidal in shape at the beginning of aging at lower temperature. By prolonging the aging time or increasing the aging temperature, Ni5P2 precipitate grows and shows a rod-like shape. The Ni added cu based lead frame material has a comparative mechanical properties with that of TAmAc15 which has been developed and used in electrical industry.
