Hybrid Machine-Learning-Based Prediction Model for the Peak Dilation Angle of Rock Discontinuities.

The peak dilation angle is an important mechanical feature of rock discontinuities, which is significant in assessing the mechanical behaviour of rock masses. Previous studies have shown that the efficiency and accuracy of traditional experimental methods and analytical models in determining the shear dilation angle are not completely satisfactory. Machine learning methods are popular due to their efficient prediction of outcomes for multiple influencing factors.

Sinomenine inhibits the inflammatory responses of human fibroblast-like synoviocytes the TLR4/MyD88/NF-κB signaling pathway in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disorder mainly characterized by inflammation of the synovial tissue that can lead to destruction of bone and cartilage. Sinomenine is an alkaloid extracted from the stem of the Chinese medicinal plant Sinomenium acutum. It has been reported that sinomenine has immunosuppressive and anti-inflammatory properties.

Sinomenine decreases MyD88 expression and improves inflammation-induced joint damage progression and symptoms in rat adjuvant-induced arthritis.

Sinomenine (SIN) is the active principle of the Chinese medical plant Sinomenium acutum which is widely used for the treatment of rheumatoid arthritis (RA) in China. Recently, several groups indicated that myeloid differentiation primary response protein 88 (MyD88) might be associated with disease progression of RA. Here, we observed the effect of SIN on MyD88 expression and showed its therapeutic role in RA.
