Exclusive decay of Υ\Upsilon into J/ψ+χc0,1,2J/\psi+\chi_{c0,1,2}

We study the $\Upsilon$ exclusive decay into double charmonium, specifically, the $S$-wave charmonium $J/\psi$ plus the $P$-wave charmonium $\chi_{c0,1,2}$ in the NRQCD factorization framework. Three distinct decay mechanisms, i.e., the strong, electromagnetic and radiative decay channels are included and their interference effects are investigated. The decay processes $\Upsilon(1S,2S,3S)\to J/\psi+\chi_{c1,0}$ are predicted to have the branching fractions of order $10^{-6}$, which should be observed in the prospective Super $B$ factory.Comment: 22 pages, 9 figures, 3 table

Effects of Yinchenhao Decoction () for Non-alcoholic Steatohepatitis in Rats and Study of the Mechanism

ObjectiveTo observe the effects of Yinchenhao Decoction () for non-alcoholic steatohepatitis (NASH) in rats and study the mechanism.MethodsTotal 18 male SD rats were randomly divided into a normal control group, a model group and a treatment group, 6 rats in each group. Rats in the model and treatment groups were fed with high-fat forage for 10 weeks to prepare the NASH model, and the rats in the treatment group were administrated with Yinchenhao Decoction from the 6th week for 5 weeks. All rats were sacrificed at the end of the10th week and the samples were collected. Serum alanine aminotransferase (ALT) activity, tumor necrosis factor-α (TNF-α) level, and hepatic triglyceride (TG) and free fatty acid (FFA) contents were determined. Hepatic pathological changes were detected by HE staining.ResultsSerum ALT activity, TNF-α level, hepatic TG and FFA contents, and the fatty deposition in hepatocytes were significantly reduced in the rats of the treatment group.ConclusionYinchenhao Decoction has good therapeutic effects for NASH, protecting the liver function and reducing the fatty deposition in liver, which are possibly related with reduction of FFA content and inhibition of TNF-α expression

2-Cyano-2-methyl­propanamide

In the crystal structure of the title compound, C5H8N2O, mol­ecules are linked via pairs of N—H⋯O hydrogen bonds, forming inversion dimers. These dimers are linked via pairs of N—H⋯H hydrogen bonds into zigzag chains propagating along [101]

N-Ethyl-3,5-dinitro­benzamide

In the title mol­ecule, C9H9N3O5, the dihedral angle between the mean planes of the amide group and the benzene ring is 31.24 (14)°. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules to form one-dimensional chains propagating in [100]

Composition and characteristics of Libyan flora

The composition, life forms and the distribution of plants in Libya were studied. The results show that in Libya there are 2103 species that belong to 856 genera and 155 families. The distribution among Libyan seed plants was characterized by a high proportion of herbs (annual to perennial), unlike the low number of woody (tree and shrub) species; these have an important influence on the structure of floral composition. The geographic element of the flora was predominantly tropical and Mediterranean. The local plants belong to representative tropical desert flora. The presence and distribution characteristics of flora in Libya show that climate, environmental condition, ecological amplitude and adaptive capacity of the plants have a determinative influence on the floristic stock in the area studies

N,4-Dimethyl­benzamide

In the crystal of the title compound, C9H11NO, mol­ecules are connected via inter­molecular N—H⋯O hydrogen bonds, forming a one-dimensional network in the b-axis direction. The dihedral angle between the amide group and the benzyl ring is 13.8 (2)°

1-Methyl-3-trifluoro­methyl-1H-pyrazol-5-ol

In the title compound, C5H5F3N2O, the F atoms are disordered over two sets of sites in a 0.64 (3):0.36 (3) ratio. In the crystal structure, O—H⋯N hydrogen bonds link the mol­ecules into chains and a short C—H⋯F contact also occurs
