Pongamia pinnata (Linn.) Pierre has anti-inflammatory activity and could significantly decrease serum tumor necrosis factor-α and IL-10 in arthritic rats. Previous research indicated the typical chemical constituent in P. pinnata is furanoflavone. Guided by anti-inflammatory active assay and UPLC-HRESIMS chromatography, 22 compounds were isolated from the ethanol extract of P. pinnata seedpods. One novel furanoflavone, 4'-hydroxypinnatin, was elucidated by HRESIMS, 1D- and 2D-NMR spectra. The 21 known compounds, including 9 furanoflavone, were identified by comparing their NMR data with the previous data in reference...

Synovium hyperplasia characterizes joint diseases, such as rheumatoid arthritis (RA). The cytotoxic effect of low-dose Cadmium (Cd) was tested in vitro and ex vivo on synoviocytes, the mesenchymal key effector cells of inflammation and proliferation in arthritis. The anti-inflammatory and anti-proliferative effects of Cd were tested in vivo by intra-articular injection in the adjuvant induced arthritis rat joints, where the clinical scores and the consequences of arthritis were evaluated. Cell death through apoptosis was highly induced by Cd in inflammatory synoviocytes (80% reduction of cell viability, p < 0...

BACKGROUND: Ursodeoxycholic acid (UDCA), also known ursodiol, is a secondary bile acid. It has been known that UDCA has prominent effects on liver, however, there is little known about its influence on autoimmune disease. Here, the benefit of UDCA on arthritis rheumatoid (RA) in vivo was tested. METHODS: RA mouse were induced using collagen II (CIA, collagen induced arthritis) where the disease severity or UDCA-related signaling pathway such as AMP-activated protein kinase (AMPK) or small heterodimer partner interacting leucine zipper protein (SMILE) was evaluated by westerblot and immunohistochemical staining...

The assessment of bone damage is required to evaluate disease severity and treatment efficacy both in arthritis patients and in experimental arthritis models. Today there is still a lack of in vivo methods that enable the quantification of arthritic processes at an early stage of the disease. We performed longitudinal in vivo imaging with [(18)F]-fluoride PET/CT before and after experimental arthritis onset for diseased and control DBA/1 mice and assessed arthritis progression by clinical scoring, tracer uptake studies and bone volume as well as surface roughness measurements...

REVIEW
Elliott M Antman
Some drugs used to treat noncardiovascular conditions may adversely impact the cardiovascular status of individuals both with and without known cardiovascular disease. When the US Food and Drug Administration judges the potential cardiovascular safety signal to be of sufficient concern, it may require the pharmaceutical manufacturer of the drug in question to conduct a postmarketing (phase 4) randomized controlled trial (RCT). Although historically many phase 4 RCTs focused on efficacy (using a superiority design), contemporary phase 4 RCTs often are focused on safety and use a noninferiority design...

Slipped capital femoral epiphysis (SCFE) remains the most common adolescent hip disorder. Most cases present with stable slips, and in situ fixation is the most commonly adopted treatment worldwide. The introduction of the concept of femoroacetabular impingement and subsequent studies have revealed SCFE-related hip impingement to be a significant pre-arthritic condition, and the previously suggested remodeling of the proximal femur after in situ fixation has been called into question. Complex proximal femoral osteotomies and more recently intra-articular procedures via surgical hip dislocation have been employed...

PURPOSE: Fractures of the base of the middle phalanx are particularly challenging. Dorsal fracture-subluxations/dislocations of the proximal interphalangeal (PIP) joint are relatively common, but the volar fracture-subluxation/dislocation, the so-called "central slip fracture," is quite rare. The current study presents our experience with surgically treated patients with central slip fracture subluxation/dislocation with a minimum of 1 year follow-up. We hypothesized that the majority of patients with a central slip fracture-subluxation/dislocation have poor outcomes...
