The glycoside hydrolase of 7-β-xylosyltaxanes (designated as LXYL-P1-2) is encoded by Lxyl-p1-2 isolated from Lentinula edodes. This hydrolase specifically removes C-7 xylose from 7-β-xylosyltaxanes to form 7-β-hydroxyltaxanes, which can be used for the semi-synthesis of paclitaxel or its analogues. In our present study, we established a high-cell-density(More)
The accumulation of misfolded α-synuclein in dopamine (DA) neurons is believed to be of major importance in the pathogenesis of Parkinson’s disease (PD). Animal models of PD, based on viral-vector-mediated over-expression of α-synuclein, have been developed and show evidence of dopaminergic toxicity, providing us a good tool to investigate potential(More)
Tissue inhibitors of metalloproteinases (TIMPs) regulate the activity of matrix metalloproteinases (MMPs) and enzymes from the a disintegrin and metalloproteinase domain with thrombospondin motifs family in osteoarthritis (OA). Elevated osteopontin (OPN) levels in plasma, synovial fluid and articular cartilage are associated with progressive OA joint(More)
The authors aimed to evaluate traffic noise level and noise annoyance in Beijing and the impact of the noise on the quality of life of the residences. The authors performed a cross-sectional study in a 12-floor college dormitory near 4th Ring Road in Beijing, China. The north-side rooms of the building were noisy and had windows facing the road. The authors(More)
Bone marrow-derived neural stem cells (NSCs) are ideal cells for cellular therapy because of their therapeutic potential for repairing and regenerating damaged neurons. However, the optimization of implanted cells and the improvement of microenvironment in the central nervous system (CNS) are still two critical elements for enhancing therapeutic effect. In(More)
Novel therapeutic targets are required for the treatment of Parkinson's disease (PD). Previous studies suggest that the Rho/Rho‑associated, coiled‑coil‑containing protein kinases (ROCKs) signaling pathway may be a promising therapeutic target in PD. To elucidate the importance of ROCKII in the pathogenesis of dopaminergic (DA) neuron loss and to investigate(More)
During immuno-mediated demyelinating lesions, endocannabinoid system participates in both inflammatory and neurodegenerative damage through several mechanisms that involve neuronal and immune cells. Here, we constructed lentiviral vector to upregulate CB1 receptor (CB1R) in the lumbar spinal cord 5–6 region and observe the effect of clinical score and(More)
The asymmetric unit of the title compound, C(11)H(11)N(3)O(2)·0.25H(2)O, contains two independent organic mol-ecules and a water mol-ecule, which lies on a twofold rotation axis. The side chains of the two mol-ecules have slightly different orientations, the C=N-N-C torsion angle being -163.03 (15)° in one and -177.52 (14)° in the other, with each adopting(More)
The title mol-ecule, C(12)H(16)N(2)O(5), adopts a trans configuration with respect to the C=N bond. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains in [001], and weak inter-molecular C-H⋯O inter-actions further link the chains into corrugated layers parallel to the bc plane.
In the title compound, C(9)H(10)N(2)O(3)·H(2)O, the Schiff base mol-ecule is approximately planar, the dihedral angle between the benzene and acetohydrazide planes being 5.40 (7)°. An intra-molecular O-H⋯O hydrogen bond is observed. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O, O-H⋯N and C-H⋯O(More)
