Abstract
A multi-spectral line-polarization motional Stark effect (MSE-MSLP) diagnostic has been developed for the Alcator C-Mod tokamak wherein the Stokes vector is measured in multiple wavelength bands simultaneously on the same sightline to enable better polarized background subtraction. A ten-sightline, four wavelength MSE-MSLP detector system was designed, constructed, and qualified. This system consists of a high-throughput polychromator for each sightline designed to provide large étendue and precise spectral filtering in a cost-effective manner. Each polychromator utilizes four narrow bandpass interference filters and four custom large diameter avalanche photodiode detectors. Two filters collect light to the red and blue of the MSE emission spectrum while the remaining two filters collect the beam pi and sigma emission generated at the same viewing volume. The filter wavelengths are temperature tuned using custom ovens in an automated manner. All system functions are remote controllable and the system can be easily retrofitted to existing single-wavelength line-polarization MSE systems.

Abstract
OBJECTIVES To define how peroxisome proliferator-activated receptor (PPAR) β/δ expression level in mesenchymal stem cells (MSCs) could predict and direct both their immunosuppressive and therapeutic properties. PPARβ/δ interacts with factors such as nuclear factor-kappa B (NF-κB) and regulates the expression of molecules including vascular cell adhesion molecule (VCAM)-1 and intercellular adhesion molecule (ICAM)-1. Since these molecules are critical for MSC function, we investigated the role of PPARβ/δ on MSC immunosuppressive properties. METHODS We either treated human MSCs (hMSCs) with the irreversible PPARβ/δ antagonist (GSK3787) or derived MSCs from mice deficient for PPARβ/δ (PPARβ/δ-/- MSCs). We used the collagen-induced arthritis (CIA) as model of immune-mediated disorder and the MSC-immune cell coculture assays. RESULTS Modulation of PPARβ/δ expression in hMSCs either using GSK3787 or hMSCs from different origin reveals that MSC immunosuppressive potential is inversely correlated with Ppard expression. This was consistent with the higher capacity of PPARβ/δ-/- MSCs to inhibit both the proliferation of T lymphocytes, in vitro, and arthritic development and progression in CIA compared with PPARβ/δ+/+ MSCs. When primed with proinflammatory cytokines to exhibit an immunoregulatory phenotype, PPARβ/δ-/- MSCs expressed a higher level of mediators of MSC immunosuppression including VCAM-1, ICAM-1 and nitric oxide (NO) than PPARβ/δ+/+ MSCs. The enhanced NO2 production by PPARβ/δ-/- MSCs was due to the increased retention of NF-κB p65 subunit on the κB elements of the inducible nitric oxide synthase promoter resulting from PPARβ/δ silencing. CONCLUSIONS Our study is the first to show that the inhibition or knockdown of PPARβ/δ in MSCs primes their immunoregulatory functions. Thus, the regulation of PPARβ/δ expression provides a new strategy to generate therapeutic MSCs with a stable regulatory phenotype.

Abstract
BACKGROUND Most interventions for childhood obesity are randomized controlled studies. Less is known about the effectiveness of clinical obesity programmes. OBJECTIVE To assess outcomes in adolescents participating in the SickKids Team Obesity Management Program (STOMP) vs. a comparison group of obese adolescents. METHODS Severely obese adolescents (n = 75) in STOMP (15.1 ± 1.8 years, body mass index [BMI] 44.8 ± 7.8 kg m(-2) ) were compared with adolescents (n = 41) not in the programme (14.9 ± 2.0 years, BMI 34.5 ± 8.0 kg m(-2) ). Outcomes were change in BMI, cardiometabolic, psychological and health behaviour measures. RESULTS At 6 months, STOMP patients' BMI was unchanged (0.08 ± 0.3; P = 0.79) and they reported improvements in quality of life and depression (-3.6 ± 1.4; P = 0.009), and increases in measures of readiness to change (RTC). Between-group differences in change between 0 and 6 months, in favour of STOMP patients, were observed for homeostatic measurement assessment-insulin resistance (HOMA-IR; -2.7 ± 1.0; P = 0.007), depression scores (-3.5 ± 1.7; P = 0.04), diet-RTC (0.6 ± 0.2; P < 0.001) and physical activity (1.7 ± 0.9; P = 0.05). At 12 months, STOMP patients increased BMI (0.8 ± 0.5; P = 0.07), but they exhibited decreased waist circumference (-7.4 ± 2.1 cm; P = 0.001) and HOMA-IR (-1.9 ± 0.6; P = 0.002). Between-group differences in change between 0 and 12 months, in favour of STOMP patients, were observed for waist circumference (-5.9 ± 2.4 cm; P = 0.01), HOMA-IR (-2.9 ± 0.7; P < 0.001) and diet-RTC (0.9 ± 0.2; P < 0.001). CONCLUSIONS STOMP participants did not experience a significant reduction in BMI but did have improvements in cardiometabolic, psychological and health behaviour outcomes. Evaluation of paediatric clinical obesity programmes using multiple measures is essential to understanding real-world outcomes.
