The complete mitochondrial genome of (Huang et al. 2019) (Cypriniformes, Nemacheilidae).

In this study, the complete mitochondrial genome of was determined for the first time. Results showed the mitogenome was 16 565 bp, including 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes and 2 non-coding regions. The overall base composition of its mitochondrial genome was 28.

[Mechanism of anti-hyperplasia of mammary glands of Xihuang Pills blood-entering component based on UPLC-Q-TOF-MS and network pharmacology].

In this study, based on network pharmacology and molecular docking method, the mechanism of anti-hyperplasia of mammary glands of Xihuang Pills blood-entering components was explored, and the efficacy and key targets of Xihuang Pills blood-entering components were experimentally verified by MCF-10A proliferation model of human mammary epithelial cells. In order to clarify the material basis and mechanism of Xihuang Pills in realizing anti-hyperplasia of mammary glands, the blood-entering components of Xihuang Pills were qualitatively analyzed by UPLC-Q-TOF-MS, and 22 blood-entering components were identified. By taking the blood-entering components as the research object, the network pharmacology prediction and molecular docking verification were carried out, and finally, three key targets were screened out, namely JAK1, SRC, and CDK1.

[Mechanism of blood-activating and mass-dissipating Chinese patent medicine against hyperplasia of mammary glands and use with other medicine: a review].

Caused by endocrine disorder, hyperplasia of mammary glands(HMG) tends to occur in the young with increasing incidence, putting patients at the risk of cancer and threatening the health of women. Therefore, the prevention and treatment of HMG is attracting more and more attention. Amid the modernization of traditional Chinese medicine(TCM), many scholars have found that Chinese patent medicine has unique advantages and huge potential in treatment of endocrine disorder.

Effects of municipal sewage sludge stabilized by fly ash on the growth of Manilagrass and transfer of heavy metals.

A greenhouse experiment was carried out to evaluate the feasibility of using an artificial soil for cultivation of Manilagrass. The transfer and transformation of heavy metals in the artificial soil-Manilagrass system were discussed at the same time. The results showed that fly ash-sludge indicated a positive effect on the growth of Manilagrass.

Isolation of new polyketide synthase gene fragments and a partial gene cluster from East China Sea and function analysis of a new acyltransferase.

Using the consensus-degenerate hybrid oligonucleotide primer polymerase chain reaction method, 26 new ketoacyl synthase (KS) fragments were isolated from a marine sediment sample in the East China Sea (ECS) and analyzed by construction of a phylogenetic tree. With a digoxigenin-labeled KS gene fragment used as a probe, a partial polyketide synthase (PKS) gene cluster was isolated and identified by hybridization screening of a marine sediment sample metagenome fosmid library constructed for this study. A new acyltransferase (AT) gene was cloned from the PKS gene cluster and heterogeneously expressed as a protein fused to maltose-binding protein (MBP).

[The preparation and application of cross-linked urease aggregates].

Urease was immobilized in a simple and effective way by physical aggregation using a precipitant-ammonium sulfate, followed by chemical cross-linking using a bifunctional reagent-glutaraldehyde to form insoluble Cross-linked urease aggregates (CLUAs). The optimum pH, optimum temperature and Km of CLUAs were 8.0, 70 degrees C and 0.

Tunable high-peak-power, high-energy hybrid Q-switched double-clad fiber laser.

A cw laser-diode-pumped Yb-doped double-clad fiber laser operating in a hybrid Q-switched regime was demonstrated. The output pulses had a duration as short as 4.2 ns, a tunable wavelength range from 1080.

Narrow-linewidth widely tunable hybrid Q-switched double-clad fiber laser.

A laser-diode-pumped Yb-doped double-clad fiber laser operating in a hybrid Q-switched regime has been demonstrated. With pulsed pump light and stimulated Brillouin scattering of the gain fiber as the Q-switching mechanisms, the laser generated nanosecond pulses with a stable repetition rate. A single-pulse energy of as much as 143.
