A comparative study on silicon nitride, titanium and polyether ether ketone on mouse pre-osteoblast cells.
Ahuja N, Awad KR, Brotto M, Aswath PB, Varanasi V. Ahuja N, et al. Among authors: aswath pb. Med Devices Sens. 2021 Feb;4(1):e10139. doi: 10.1002/mds3.10139. Epub 2020 Oct 22. Med Devices Sens. 2021. PMID: 35765350 Free PMC article.
There was more profound and faster ECM deposition and mineralization on Si(3)N(4) surface as compared to titanium and PEEK. The FTIR and Raman spectroscopy show formation of collagen and mineral deposition at 30 days for Si(3)N(4) and titanium and not PEEK. The peaks shown …

Material properties of bone in the femoral head treated with ibandronate and BMP-2 following ischemic osteonecrosis.
Aruwajoye OO, Aswath PB, Kim HKW. Aruwajoye OO, et al. Among authors: aswath pb. J Orthop Res. 2017 Jul;35(7):1453-1460. doi: 10.1002/jor.23402. Epub 2016 Sep 22. J Orthop Res. 2017. PMID: 27564450 Free article.
There were five groups: normal control, untreated, IB, BMP, and BMP + IB (n = 5/group). Backscattered electron imaging, Raman spectroscopy, and nanoindentation testing were performed. Both BMP and BMP + IB groups showed calcium content in the trabecular bone similar to the …

The in vivo role of DMP-1 and serum phosphate on bone mineral composition.
Maginot M, Lin S, Liu Y, Yuan B, Feng JQ, Aswath PB. Maginot M, et al. Among authors: aswath pb. Bone. 2015 Dec;81:602-613. doi: 10.1016/j.bone.2015.08.018. Epub 2015 Aug 22. Bone. 2015. PMID: 26303287
To address the direct contribution of P to the in vivo bone mineralization we analyzed the properties of femurs obtained from Dmp1 null mice and wild type (WT) mice under a normal or high phosphorous (HiP) diet using combined assays, including histological examination, micro comp …

Silicon nitride enhances osteoprogenitor cell growth and differentiation via increased surface energy and formation of amide and nanocrystalline HA for craniofacial reconstruction.
Awad KR, Ahuja N, Shah A, Tran H, Aswath PB, Brotto M, Varanasi V. Awad KR, et al. Among authors: aswath pb. Med Devices Sens. 2019 Apr;2(2):e10032. doi: 10.1002/mds3.10032. Epub 2019 May 6. Med Devices Sens. 2019. PMID: 35781939 Free PMC article.
Si(3)N(4) surface induced highest surface coverage and thickness of nanocrystalline HA (211) and (203) in cell-free in vitro studies after 7 days of culture. Raman spectroscopy analysis confirmed the presence of surface functional groups consisting of phosphate and carbona …

Bone apatite composition of necrotic trabecular bone in the femoral head of immature piglets.
Aruwajoye OO, Kim HK, Aswath PB. Aruwajoye OO, et al. Among authors: aswath pb. Calcif Tissue Int. 2015 Apr;96(4):324-34. doi: 10.1007/s00223-015-9959-7. Epub 2015 Feb 7. Calcif Tissue Int. 2015. PMID: 25660159
Scanning electron microscopy (SEM), histology, X-ray absorbance near edge structure (XANES), and Raman spectroscopy were performed on femoral heads to characterize normal and necrotic trabecular bone. Backscattered SEM, micro-computed tomography and histology showed deform …
