Consistent with its lack of phototropic function in Arabidopsis, Otphot does not associate with or trigger dephosphorylation of the phototropic signalling component Non-Phototropic Hypocotyl 3 (NPH3). Taken together, these findings indicate that the mechanism of action of plant and evolutionarily distant algal phots is less well conserved than previously thought. To investigate the association between features of ultrasound-detected inflammation and development of erosive disease in patients with hand osteoarthritis (OA) over 2.3 years of followup. The study group comprised 56 consecutive patients with hand OA (mean age 61 years, 86% female) fulfilling the American College of Rheumatology criteria. Effusion, synovial thickening, and power Doppler signal in all interphalangeal (IP) joints were assessed with ultrasonography, using standardized methods, at baseline and followup. Radiographs were scored at both time points for osteophytes/joint space narrowing using the Osteoarthritis Research Society International method and for erosive disease (E phase [erosive] and R phase [remodeling]) using the method described by Verbruggen and Veys. Erosion development was defined as progression from N phase (normal) to E phase or R phase. Joints that were in E phase or R phase at baseline were excluded. Associations were analyzed using generalized estimating equations with adjustment for age, sex, body mass index, and baseline structural abnormalities. At baseline, 51 IP joints (in 18 patients) and at followup 89 IP joints (in 26 patients) had erosions; thus, erosions developed in 38 IP joints. Moderate/severe synovial thickening and a power Doppler signal at baseline were associated with erosion development (adjusted odds ratio [OR] 8.8, 95% confidence interval [95% CI] 2.4-32.3 and OR 7.1, 95% CI 1.9-26.9, respectively).
