In a population of asymptomatic volunteers across 5 countries, we sought to (a) establish normative values of the Odontoid-Central Sacral Vertical Line (OD-CSVL) across patient factors, and (b) assess correlations of OD-CSVL with other radiographic parameters. A prospective, cross-sectional study of asymptomatic adult volunteers, ages 18-80years, were enrolled across 5 countries (France, Japan, Singapore, Tunisia, United States) forming the Multi-Ethnic Alignment Normative Study (MEANS) cohort. Included volunteers had no known spinal disorder(s), no significant neck/back pain (VAS ≤ 2; ODI ≤ 20), and no significant scoliosis (Cobb ≤ 20°). Radiographic measurements included commonly used coronal alignment parameters (mm) and angles (°). Proteasome inhibitor drugs OD-CSVL was defined as the difference between the odontoid plumb line (line from the tip of the odontoid vertically down) and the CSVL (vertical line from the center of the sacrum). Chi-square, student's t tests, Kruskal-Wallis, Wilcoxon rank-sum, linear regression, and Peasymptomatic volunteers, increased OD-CSVL was significantly associated with increased age, increased BMI, and ethnicity, but not gender. OD-CSVL correlated strongest with C7-CSVL, TL cobb angle, OD-knee, and CAM-knee. OD-CSVL. These results support further study of OD-CSVL in symptomatic adult spine deformity patients. RTX could be an effective and safe alternative treatment for refractory EF. Rituximab (RTX) is a successful therapeutic option for various autoimmune diseases. Our aim is to report our experience with RTX in eosinophilic fasciitis (EF) and review published data on its efficacy for the treatment of EF. We reviewed the medical charts of all patients with a diagnosis of EF treated with RTX from 2008 to 2020 in the Department of Rheumatology and Clinical Immunology in the University Hospital of Heraklion, Crete, Greece. We also reviewed the English literature for cases of EF treated with RTX. Demographics, clinical manifestations, laboratory findings, prior treatments, response to RTX, cumulative RTX dose, duration of treatment and follow-up are reported. We report three cases of EF refractory to conventional DMARDs (cDMARDs) that responded to RTX. Furthermore, literature review revealed five cases. In our case series in all patients, RTX was the first biologic. RTX could be effective in cases of (EF) refractord be effective in cases of (EF) refractory to standard immunosuppressive treatment.Osteocytes are believed to play a crucial role in mechanosensation and mechanotransduction which are important for maintenance of mechanical integrity of bone. Recent investigations have revealed that the preferential orientation of bone extracellular matrix (ECM) mainly composed of collagen fibers and apatite crystallites is one of the important determinants of bone mechanical integrity. However, the relationship between osteocytes and ECM orientation remains unclear. In this study, the association between ECM orientation and anisotropy in the osteocyte lacuno-canalicular system, which is thought to be optimized along with the mechanical stimuli, was investigated using male rat femur. The degree of ECM orientation along the femur longitudinal axis was significantly and positively correlated with the anisotropic features of the osteocyte lacunae and canaliculi. At the femur middiaphysis, there are the osteocytes with lacunae that highly aligned along the bone long axis (principal stress direction) and canaliculi that preferentially extended perpendicular to the bone long axis, and the highest degree of apatite c-axis orientation along the bone long axis was shown. Based on these data, we propose a model in which osteocytes can change their lacuno-canalicular architecture depending on the mechanical environment so that they can become more susceptible to mechanical stimuli via fluid flow in the canalicular channel. Traditional knowledge dissemination methods have been ineffective in leading to timely and widespread changes in clinical practice. Social media has the potential to reach broader audiences than more traditional methods to disseminate research findings. We evaluated the effectiveness of using social media to mobilize knowledge about pain in dementia. We developed an online repository of evidence-based content (e.g., guidelines, assessment approaches) and a video about pain in dementia. The video was uploaded on YouTube, a video sharing platform. We collaborated with stakeholder organizations on a 5-month social media campaign (#SeePainMoreClearly) on Twitter, a social networking site, to disseminate digital content about pain in dementia. The response to our initiatives was evaluated using web/social media metrics, a video questionnaire, and by comparing the extent of Twitter discussions about pain in dementia before and during the campaign period. Web metrics showed a great reach of the initiative the ent of social media initiatives in other health disciplines.Extreme temperature conditions seriously impair male reproductive development in plants; however, the molecular mechanisms underlying the response of anthers to extreme temperatures remain poorly described. The transcription factor PHYTOCHROME-INTERACTING FACTOR4 (PIF4) acts as a hub that integrates multiple signaling pathways to regulate thermosensory growth and architectural adaptation in plants. Here, we report that SlPIF4 in tomato (Solanum lycopersicum) plays a pivotal role in regulating cold tolerance in anthers. CRISPR/Cas9-generated SlPIF4 knockout mutants showed enhanced cold tolerance in pollen due to reduced temperature sensitivity of the tapetum, while overexpressing SlPIF4 conferred pollen abortion by delaying tapetal programmed cell death (PCD). SlPIF4 directly interacts with SlDYT1, a direct upstream regulator of SlTDF1, both of which (SlDYT1 and SlTDF1) play important roles in regulating tapetum development and tapetal PCD. Moderately low temperature (MLT) promotes the transcriptional activation of SlTDF1 by the SlPIF4-SlDYT1 complex, resulting in pollen abortion, while knocking out SlPIF4 blocked the MLT-induced activation of SlTDF1. Furthermore, SlPIF4 directly bind to the canonical E-box sequence in the SlDYT1 promoter. Collectively, these findings suggest that SlPIF4 negatively regulates cold tolerance in anthers by directly interacting with the tapetal regulatory module in a temperature-dependent manner. Our results shed light on the molecular mechanisms underlying the adaptation of anthers to low temperatures.
