In the last few years, charge order and its entanglement with superconductivity are under hot debate in high-tc community due to the new progress on charge order in high-tc cuprate superconductors YBa2Cu3O6+x. Here, we will briefly introduce the experimental status of this field and mainly focus on the experimental progress of high-field nuclear magnetic resonance(NMR) study on charge order in YBa2Cu3O6+x. the pioneering high-field NMR work in YBa2Cu3O6+x sets a new stage for studying charge order which has become a ubiquitous phenomenon in high-tc cuprate superconductors.

Over the past decade,miRNAs have emerged as genetic factors that can influence immune functions.1 they act by post-transcriptionally downregulating gene expression either by degrading target mRNAs or by repressing their translation.2 Linking miRNA expression to disease was first accomplished by comparing outcomes in normal animals with those in miR-155 knockout animals.3 Our group also used a viral pathogen to show that knocking out miR-155 resulted in less severe inflammatory lesions caused by herpes simplex virus infection,yet animals without miR-155 became more susceptible to developing viral encephalitis.

Cordycepin was the first adenosine analogue used as an anticancer and antiviral agent, which is extracted from Cordyceps militaris and hasn’t been biosynthesized until now. this study was first conducted to verify the role of ribonucleotide reductases(RNRs, the two RNR subunits, RNRL and RNRM) in the biosynthesis of cordycepin by over expressing RNRs genes in transformed C. militaris. Quantitative real-time PCR(qRt-PCR) and western blotting results showed that the m RNA and protein levels of RNR subunit genes were significantly upregulated in transformant C. militaris strains compared to the control strain. the results of the HPLC assay indicated that the cordycepin was significantly higher in the C. militaris transformants carrying RNRM than in the wildtype strain, whereas the RNRML was preferentially downregulated. For the C. militaris transformant carrying RNRL, the content of cordycepin wasn’t remarkably changed. Furthermore, we revealed that inhibiting RNRs with triapine(3-AP) almost abrogated the upregulation of cordycepin. therefore, our results suggested that RNRM can probably directly participate in cordycepin biosynthesis by hydrolyzing adenosine, which is useful for improving cordycepin synthesis and helps to satisfy the commercial demand of cordycepin in the field of medicine.

Phillip Zarrilli is an acting teacher whose pedagogy incorporates the Asian disciplines of hatha yoga, kalarippayattu, and t ＇ai chi ch ＇uan. His intercultural pedagogy would be best labeled as ＂psychophysical＂ based on his own assertions and when bearing in mind the traditions that he considers most personally influential, all of which have intercultural elements, both Western and Asian. this paper examines Zarrilli＇s personal origins, his pedagogy, his teaching influences, and his legacy based on his artistic progeny. Information was gathered through interviews, personal observation, on-site participation, and literature. the subjects of these analyses were： the disciplines of Asian origin relevant to Zarrilli＇s pedagogy; how his teaching influences his students; Zarrilli＇s personal development from university to his present international teaching, directing, and writing; his past and current projects; and what his work means today.

Nano cerium oxide films were applied on AA7020-t6 aluminum alloy and the effects of acetic acid concentration on the microstructure and electrochemical properties of the coated samples were investigated by using scanning electron microscopy （SEM）, X-ray diffraction （XRD）, and potentiodynamic polarization methods. It has been found that by increasing the acetic acid/CeCl3·7H2O molar ratio, high uniform and crack-free films with well-developed grains were obtained and grain sizes of the films decreased. Elimination of cracks and decreasing grain size of the nano cerium oxide films caused corrosion resistance to increase.

Background： Fat deposits in chickens contribute significantly to meat quality attributes such as juiciness, flavor, taste and other organoleptic properties. the quantity of fat deposited increases faster and earlier in the fast- growing chickens than in slow-growing chickens. In this study, Affymetrix Genechip~ Chicken Genome Arrays 32773 transcripts were used to compare gene expression profiles in liver and hypothalamus tissues of fast-growing and slow-growing chicken at 8 wk of age. Real-time Rt-PCR was used to validate the differential expression of genes selected from the microarray analysis. the mRNA expression of the genes was further examined in fat tissues. the association of single nucleotide polymorphisms of four lipid-related genes with fat traits was examined in a F2 resource population. Results： Four hundred genes in the liver tissues and 220 genes hypothalamus tissues, respectively, were identified to be differentially expressed in fast-growing chickens and slow-growing chickens. Expression levels of genes for lipid metabolism （SULtIB1, ACSBG2, PNPLA3, LPL, AOAH） carbohydrate metabolism （MGAt4B, XYLB, GBE1, PGM1, HKDCl）cholesttrol biosynthesis （FDPS, LSS, HMGCR, NSDHL, DHCR24, IDI1, MEI） HSD17B7 and other reaction or pro- cesses （CYPIA4, CYP1A1, AKR1BI, CYP4V2, DDO） were higher in the fast-growing White Recessive Rock chickens than in the slow-growing Xinghua chickens. On the other hand, expression levels of genes associated with multicellular organism development, immune response, DNA integration, melanin biosynthetic process, muscle organ develop- ment and oxidation-reduction （FRZB, DMD, FUt8, CYP2C45, DHRSX, and CYP2C18） and with glycol-metabolism （GCNt2, ELOVL d, and FASN）, were higher in the XH chickens than in the fast-growing chickens, fit-PCR validated high expression levels of nine out of 12 genes in fat tissues. the G1257069A and t1247123C of the ACSBG2 gene were significantly associated with abdominal fat weight. the G4928024A of the FASN ge
