“…This is most apparent when the measurements BC, BD, and CD are compared to one another as they produce a pyramidal shape. If the geometry of the pelvis between the 3D model and the CT data were to be discordant, there would be further discrepancies among the three measurements [17]. More advanced and thorough methods, such as optical 3D scanning [8] and surface shape analysis would have provided additional information on the accuracy between the model and the CT data but this was unavailable to the authors.…”

Accuracy and precision of measurements performed on three-dimensional printed pelvises when compared to computed tomography measurements

The preoperative contouring of plates decreases the duration of surgery and improves the quality of the reduction of pelvic fractures. Patient-tailored three-dimensionally printed pelvises might be an interesting tool for achieving that purpose. Currently, no study has evaluated the accuracy of measurements performed on three-dimensional printed models in comparison with computed tomography data for complex bones, such as the pelvis. This study examined whether the measurements obtained on pelvises printed using dual-material fused deposition modeling technology are not significantly different from those obtained on computed tomography images. The computed tomography images of the pelvic region from 10 dogs were used to produce three-dimensionally printed models with a dual-material fused deposition-modeling process. Four segments were measured on both three-dimensionally printed models and computed tomography images. The measurements were performed by three observers and repeated twice. Concordance correlation coefficients were used to assess the precision and accuracy of the measurements as well as evaluate the agreement between the methods. The accuracy of measurements between the methods was > 0.99 for all measurements. The precision was almost perfect for AE (0.996), substantial for BD and BC (0.963 and 0.958, respectively), and moderate for CD (0.912). These results indicate that, despite some minor variations, the measurements performed on printed models reproduced the computed tomography data reliably.

“…Direct measurements of the lengths of the four segments were performed on the 3D models with a scientific digital caliper with a precision of 0.1 mm on each printed model. Using this method and the concept of geometrical analysis, a limited evaluation of the pelvic morphology was also performed [1617].…”

“…Metal NPs derived from mushrooms have been reported in literature to inhibit the growth of numerous foodborne pathogenic bacteria and fungi. The inhibition of AgNPs on the bacterial cells has been attributed to direct physical contact of metal nanoparticles with bacterial membranes which caused the release of intercellular materials, loss of cell membrane integrity and cell death [39]. Other researchers reported that the subsequent release of Ag + ions by the nanoparticles resulted in DNA damage, protein denaturation and enzyme inhibition [40].…”

Aims: The study aimed to synthesize silver nanoparticles (AgNPs) from aqueous AgNO3 using phytochemicals present in Pleurotus ostreatus and assess the AgNPs antibacterial activity on Bacillus subtilis and Providencia rettgeri. Study design: Experimental/Analytical. Place and Duration of Study: Bells University of Technology between December 2020 and August 2021. Methodology: The mushroom was washed, dried, pulverized and 5g stirred into 100ml deionized water. The solution was sonicated using ultrasonic cleaner at 40 oC for 40 min, centrifuged at 4000 rpm for 10 min. The supernatant was filtered, and 1ml filtrate was mixed with 9 ml of 10mM AgNO3. After the reaction period, the mixture was centrifuged at 15,000 rpm for 15 min. The residues were washed thrice with deionized water and dried. Synthesis of AgNPs was monitored by UV–Vis spectrophotometer, characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction analysis. Antibacterial analysis was done by agar well diffusion using gentamicin as control. Results: A dark brown colour change and UV visible spectroscopy peak at 400 nm confirmed the formation of AgNPs. Fourier transform infrared spectroscopy analysis showed the presence of functional groups involved in the reduction of AgNO3. GCMS performed on the methanolic extract of Pleurotus ostreatus showed the presence of 37 organic compounds, among them were cathecol, hydroquinone and phenols etc. Antimicrobial activity revealed that AgNPs inhibited the growth of B. subtilis and P. rettgeri. Conclusion: The study revealed that Pleurotus ostreatus effectively synthesized AgNPs and the AgNPs inhibited the growth of Providencia rettgeri and Bacillus subtilis and can play major roles in the field of medical and pharmaceutical nanotechnology.
