A full-field hard X-ray imaging beamline (BL-4) was designed, developed, installed and commissioned recently at the Indus-2 synchrotron radiation source at RRCAT, Indore, India. The bending-magnet beamline is operated in monochromatic and white beam mode. A variety of imaging techniques are implemented such as high-resolution radiography, propagation- and analyzer-based phase contrast imaging, real-time imaging, absorption and phase contrast tomography etc. First experiments on propagation-based phase contrast imaging and micro-tomography are reported.

Aim to compare anulom vilom pranayama (AVP), kapal bhati pranayama (KBP), diaphragmatic breathing exercises (DBE), and pursed-lip breathing (PLB) for breath holding time (BHT) and rating of perceived exertion (RPE). Methods- Participants were assessed for BHT and RPE, before training on any one intervention using online platforms, for one week during lockdown from COVID-19.15 participants in each group total N = 60 at- (α – 0.05), (1- β – 0.90) & (effect size - 0.55); were analysed. Results - AVP & DBE decreased RPE (p < 0.000). KBP & PLB did not decrease RPE as compared to AVP & DBE (p. > 0.05). DBE increased BHT more than KBP & PLB interventions (p < 0.05), but not more than AVP (p > 0.05). One-way ANOVA of four interventions revealed significant variation for RPE change (p < 0.05), for AVP. Conclusions - AVP reduces RPE maximally during breath-holding, whereas DPE increases BHT more.

Background:Tibial plateau fractures are usually associated with communition and soft tissue injury. Percutaneous treatment of these complex fractures is intended to reduce soft issue complications and postoperative stiffness of the knee joint. We assessed the complications, clinical outcome scores, and postoperative knee range of movements, after fluoroscopic assisted closed reduction and external fixator application.Materials and Methods:Seventy eight complex tibial plateau fractures in 78 patients were included in the study. All fractures were managed with closed reduction and external fixator application. In 28 cases with intraarticular split, we used percutaneous cancellous screw fixation for reduction and fixation of condylar parts. In nine open fractures, immediate debridement was done. In 16 cases, elevation of depressed segment and bone grafting was required, which was done from a very small incision. All patients were clinically and radiographically evaluated at a mean followup of 26.16 months (range 6–60 months).Results:Clinical results were evaluated according to the Rasmussen's criteria. Average healing time was 13.69 weeks (range 12– 28 weeks). Mean knee range of motion was 122.60° (range 110°–130°). Forty seven results were scored as excellent, 25 good, 2 fair, and 1 as poor.Conclusion:We believe that minimally invasive treatment by percutaneous techniques and external fixation is a fairly reasonable treatment alternative, if near anatomical reduction of joint surface can be confirmed on fluoroscopy.
