Pre-treatment of rapamycin transformed M2 microglia alleviates traumatic cervical spinal cord injury via AIM2 signaling pathway in vitro and in vivo.

Background: Traumatic spinal cord injury (SCI) is still devastating. It was suggested that the inhibition of mTOR may alleviate neuronal inflammatory injury but its underlying mechanism remained to be elucidated. AIM2 (absent in melanoma 2) recruits ASC (apoptosis-associated speck-like protein containing a CARD) and caspase-1 to form the AIM2 inflammasome, activate caspase-1, and elicit inflammatory responses.

Flavonoids from the roots of Artocarpus heterophyllus.

Four new flavonoids, artoheteroids A-D (1-4), together with six known ones (5-10), were isolated from the roots of Artocarpus heterophyllus. Their structures were elucidated by spectroscopic methods, including 1D and 2D NMR, UV, IR, CD, and HR-ESI-MS. All isolated compounds were screened for their inhibitory abilities against cathepsin K (CatK).

Isoprenylated Flavonoids from Roots of Artocarpus styracfolius.

Seven isoprenylated flavonoids were isolated from Artocarpus styracifolius, including one new triisoprenylated flavone, styracifolin D (1,) and six known ones, artocarpone B (2), kuwanon C (3), 6-C-prenyl luteolin (4), albanin A (5), 2,4,2',4'-tetrahydroxy-3'-(3-methyl-2-butenyl)-chalcone (6), and 3'-[γ-hydroxymethyl-(E)- γ-methylallyl]-2,4,2',4'-tetrahydroxychalcone 11'-0-coumarate (7). The structures of these compounds were determined by analysis of their spectroscopic and mass spectrometric data. Of them, 3 and 5 exhibited inhibitory effects on cathepsin K with IC(50) values of 114.

[Traditional Chinese medicine inheritance system analysis of professor Ding Yuanqing in treating tic disorder medication based on experience].

In recent years, the incidence of tic disorders has increased, and it is not uncommon for the patients to treat the disease. The pathogenesis and pathogenesis of Western medicine are not yet clear, the clinical commonly used western medicine has many adverse reactions, traditional Chinese medicine (TCM) research is increasingly valued. Based on the software of TCM inheritance assistant system, this paper discusses Ding Yuanqing's experience in treating tic disorder with Professor.

Theoretical studies on cycloaddition reactions between the 2-aza-1,3-butadiene cation and olefins.

Density functional (B3LYP) calculations, using the 6-31G basis set, have been employed to study the title reactions. For the model reaction (H(2)C=C-NH(+)=CH(2) + H(2)C=CH(2)), a complex has been formed with 6.2 kcal/mol of stabilization energy and the transition state is 4.
