The plausible nitric oxide (NO)-sensing module of TRPC5 was incorporated in a enhanced green fluorescent protein (EGFP) to evaluate its conformational change as an optical response upon the reaction with NO. Two cysteine residues located in the NO-sensing module have been proposed to form a disulfide bond through S-nitrosylation of the thiol group by NO. Modification of the cysteine residues by NO resulted a ratiometric change of EGFP emission through transducing the conformational change of NO-sensing module to the EGFP chromophore. The oxidized form of NO-sensing module fused EGFP changed the intensity of emission spectra upon reduction of the disulfide bond at the NO-reactive module. The NO-sensing module fused EGFP in its reduced form avidly reacted with NO and realized the ratiometric fluorescence intensity changes depending on the formation of disulfide bond. These results support the notion that NO induces a conformational change at the putative NO-sensing segment of TRPC5, and provide a prototype for the genetically encoded cellular NO sensors. Nonhuman primates (NHP) are important pre-clinical models for evaluation of the safety and efficacy of the most promising potential therapeutic advances in organ transplantation based on rodent studies. Although rare, dendritic cells (DC) play important roles in preservation of self tolerance and DC with immunoregulatory properties (regulatory DC; DCreg) can promote transplant tolerance in rodents when adoptively transferred to allograft recipients. NHP DCreg can be generated ex vivo from bone marrow precursors or blood monocytes of cynomolgus or rhesus macaques or baboons. NHP DCreg generated in the presence of anti-inflammatory factors that confer stability and resistance to maturation, subvert alloreactive T cell responses. When infused into rhesus renal allograft recipients before transplant, they safely prolong MHC mis-matched graft survival, associated with attenuation of anti-donor immune reactivity. In this concise review we describe the properties of NHP DCreg and discuss their influence on T cell responses, alloimmunity and organ transplant survival. Epacadostat manufacturer BACKGROUND & AIMS For many decades diet, mainly its "pro-inflammatory" quality has been pondered as a possible risk factor for developing MS. However, the complexity of different dietary composition analysis provided controversial results. Recently a dietary inflammatory index (DII), a population-based score, was developed to objectify the inflammatory characteristics of a specific dietary intake. METHODS We investigated the potential association between DII (expressed as energy adjusted-DII (E-DII) and non-energy adjusted DII (DII)) assessed from a validated FFQ based on the participants' diet habits during adolescence and the risk for developing MS in a population-based incident case-control study. Multiple logistic regression was used to estimate the adjusted. RESULTS We recruited 547 incident MS cases and 1057 general population controls from Tehran, Iran (August 2013-February 2015). A statistically significant higher risk of MS was found in analyses using E-DII scores as a continuous variable with an adjusted odds ratio (AOR) of 1.53 (95% confidence interval (CI) 1.42-1.65, P = 0.001), and as a categorical variable (4th quartile OR 7.01, 95% CI 4.87-10.1, vs the first quartile), test for trend; OR 1.86 (95% CI 1.67-2.07), P for trend less then 0.001. A similar pattern was demonstrated for DII score and risk for MS. CONCLUSIONS We identified a pro-inflammatory diet characterized by higher E-DII and DII scores during adolescence as a strong risk factor for MS onset. Given the worldwide role of diet in general population health, improving nutritional pattern through educational programs is likely to reduce MS risk. BACKGROUND The variation in the anatomic relationship between the coracoid and the clavicle affects the biomechanical stability of coracoclavicular ligament reconstruction (CCLR). METHODS Three-dimensional computed tomography reconstruction of 85 patients was analyzed. Anatomic landmarks were used to derive the coracoclavicular sagittal reconstruction angle (sRA). The lateral concave angle, which indicated the shape of the distal clavicle, and the offsets between the clavicle and coracoid were also measured. To investigate the biomechanical effects of the sRA on CCLR, 7 computed tomography scans with different sRAs were 3D printed. Two reconstructions, a single trans-coracoclavicular tunnel and a looped reconstruction technique, were performed sequentially. Models were cyclically loaded at 70 N in the anterior, posterior, and superior directions. RESULTS The mean sRA was 68° ± 9.3° (range, 47°-85°). The superoinferior offset between the clavicle and the coracoid and the lateral concave angle positively correlated with the sRA (r = 0.359 and 0.837, respectively; P ≤ .001), whereas the anteroposterior offset had a negative correlation (r = -0.925; P less then .001). The sRA had a negative correlation with the anterior displacement of the clavicle (rho = -0.96; P less then .001) and a positive correlation with the posterior displacement for both surgical techniques (rho = 1.0; P less then .001). CONCLUSION The anatomic orientation of the native coracoclavicular ligaments is highly variable in the sagittal plane. Low sagittal angles can reduce anterior stability, whereas high sagittal angles can reduce posterior stability of CCLR. HYPOTHESIS AND BACKGROUND Injuries to the elbow medial ulnar collateral ligament (mUCL) pose a diagnostic challenge, with the moving valgus stress test (MVST) currently accepted as the gold-standard clinical test. This study sought to biomechanically evaluate the change in length of the ulnar collateral ligament (UCL) during flexion-extension using a null hypothesis that the mUCL will not experience a greater change in length with movement than with static loading. METHODS Seven fresh-frozen human cadaveric elbows were tested with static and dynamic valgus stress. We measured (1) ligament length with a multi-camera optical system, (2) elbow flexion with an incremental encoder, and (3) valgus deviation with an electronic inclinometer. With a force applied to the wrist to simulate a clinical stress examination, the elbow was flexed and extended in a physiological elbow simulator to mimic the flexion and extension of the MVST. RESULTS The simulated MVST produced more elongation of the UCL compared with static stress testing (P less then .
