Preparation and cytocompatibility of Ni-Ti-O nanospindles on NiTi alloy

Publication date: Available online 17 September 2019Source: Materials LettersAuthor(s): Si Liu, Ya Zhao, Yanlian Liu, Xiaohong Yao, Peide Han, Ruiqiang Hang, Jin ZhangAbstractThe present work reports on the hydrothermal conversion of Ni-Ti-O nanopores anodically grown on NiTi alloy into nanospindles and their cytocompatibility. The results show the amorphous nanopores can transform to antase nanospindles with length concentrated at 70-110 nm and diameter at 16-24 nm upon hydrothermal treatment at 200 oC in pure water for 2 h. The nanospindles also can promote proliferation of bone marrow mesenchymal stem cells when compared with that of nanopores and bare NiTi alloy thus are promising as biomedical coatings of NiTi alloy.

Non-integrating episomal vectors coding OCT4, SOX2, KLF4, BCL-XL and MYC were used for reprogramming. The established iPSC line contained the s...

Authors: Freeman FE, Browe DC, Nulty J, Von Euw S, Grayson WL, Kelly DJ Abstract Interconnected porosity is critical to the design of regenerative scaffolds, as it permits cell migration, vascularisation and diffusion of nutrients and regulatory molecules inside the scaffold. 3D printing is a promising strategy to achieve this as it allows the control over scaffold pore size, porosity and interconnectivity. Thus, the aim of the present study was to integrate distinct biofabrication strategies to develop a multiscale porous scaffold that was not only mechanically functional at the time of implantation, but also faci...

We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understanding of how the effects of genetic variants are channeled through distinct molecular layers is still limited. To address this, we employed a systems genetics approach on the gut transcriptomes from 38 control and orally...

Chakrabarti, Patrick J. McGahan, James L. ChenAbstractAnterior cruciate ligament (ACL) tears are unfortunate but common injuries in the athletic population. The standard of care for ACL tears is a surgical intervention to reconstruct the ACL to restore knee functionality as well as quality of life. In recent years, bone marrow aspirate concentrate (BMAC) has seen increasing use in various orthopaedic settings. This increase can be attribu...

This study demonstrated that the application of lovastatin enhanced the osteogenic differentiation of cell spheroids formed from GDSCs. This suggests that combinations of lovastatin and stem cell spheroids may have the potential for use in tissue engineering. PMID: 31602217 [PubMed]

Conclusions: PICU mortality of pediatric cancer and hematopoietic stem cell transplant patients requiring continuous renal replacement therapy is sadly high. Fluid overload at the initiation of continuous renal replacement therapy is the most important and earliest predictor of PICU mortality. Our results suggest that the most commonly used criteria of acute kidney injury, that is, serum creatinine and urine production, are not useful as a trigger to initiate continuous renal replacement therapy. This highlights the urgent need for prospective studies to generate recommendations for effective therapeutic interventions at...

This study was carried out on 80 neonates divided into; group I (30 preterm neonates) with AOP received EPO (250 IU/kg/dose subcutaneously 3 times weekly for 4 weeks), compared to group II (30 neonates) with AOP treated only with blood transfusion; Group III(10 neonates, GA ≥ 37 weeks) with late hypo-regenerative post haemolytic anemia, treated with the same dose of r-Hu EPO and compared to group IV (10 neonates) treated only with blood transfusion. Hematological measurements and transfusion requirements were followed during therapy. Serum level of EPO was measured by ELISA technique.ResultsBy the end of the 4th week of...
