Open for Nominations: 2021 Biomaterials Science Lectureship

 

Do you know an early-career researcher who deserves recognition for their contribution to the biomaterials field?

Now is your chance to put them forward for the accolade they deserve!

Biomaterials Science is pleased to announce that nominations are now being accepted for its 2021 Lectureship award. This annual award was established in 2014 to honour an early-stage career scientist who has made a significant contribution to the biomaterials field.

The recipient of the award will be asked to present a lecture at European Society for Biomaterials Annual Meeting in Porto in September 2021, where they will also be presented with the award. The Biomaterials Science Editorial Office will provide £1000 financial support to the recipient for travel and accommodation costs.

The recipient will also be asked to contribute a research article to the journal and will have their work showcased free of charge on the front cover of the issue in which their article is published. The article would be subject to the normal peer review standards of the journal.

 

Previous winners

2020 – Kanyi Pu, Nanyang Technological University, Singapore

2019 – April Kloxin, University of Delaware, USA

2018 – Zhen Gu, University of North Carolina at Chapel Hill & North Carolina State University, USA

2017 – Zhuang Liu, Soochow University, China

2016 – Fan Yang, Stanford University, USA

2015 – Joel Collier, Duke University, USA

2014 – Suzie Pun, University of Washington, USA

 

Eligibility

To be eligible for the lectureship, candidates should meet the following criteria:

  • Be an independent researcher, having completed PhD and postdoctoral studies
  • Be actively pursuing research within the biomaterials field, and have made a significant contribution to the field
  • Be at an early stage of their independent career (this should be within 12 years of attaining their doctorate or equivalent degree, but appropriate consideration will be given to those who have taken a career break or followed an alternative study path)

Although the Biomaterials Science Lectureship doesn’t explicitly reward support of or contributions to the journal, candidates with a history of publishing or reviewing for the journal would be more likely to be considered favourably.

 

Selection

  • All eligible nominated candidates will be assessed by a shortlisting panel, made up of members of the Biomaterials Science Advisory Board and a previous lectureship winner.
  • The shortlisting panel will consider the nomination form and letter of recommendation, as well as the three recent research articles highlighted in the nomination form for consideration.
  • Shortlisted candidates will be further assessed by the Biomaterials Science Editorial Board, and a winner will be selected based on an anonymous poll.
  • Selection is not based simply on quantitative measures. Consideration will be given to all information provided in the letter of recommendation and nomination form, including research achievements and originality, contributions to the biomaterials community, innovation, collaborations and teamwork, publication history, and engagement with Biomaterials Science.

 

Nominations

Nominations must be made via email to biomaterialsscience-rsc@rsc.org, and include the following:

  • A brief letter of recommendation (1 page maximum length)
  • A complete nomination form (includes list of the candidate’s relevant publications or recent work, 3 research articles to be considered during the shortlisting process, candidate’s scientific CV, and full contact details)

Please note:

  • Nominations from students and self-nomination is not permitted.
  • The nominee must be aware that he/she has been nominated for this lectureship.
  • As part of the Royal Society of Chemistry, we have a responsibility to promote inclusivity and accessibility in order to improve diversity. Where possible, we encourage each nominator to consider nominating candidates of all genders, races, and backgrounds. Please see the RSC’s approach to Inclusion and Diversity.
  • Candidates outside of the stated eligibility criteria may still be considered.

 

Nominations deadline: 30th November 2020

Oversized composite braided biodegradable stents with post-dilatation for pediatric applications: mid-term results of a porcine study

Biodegradable stents (BDSs) have proven to be better compared to permanently implanted metallic stents for the treatment of endovascular diseases in children.  Currently, BDSs that are made out of polylactic acid (PLA) with degradation times of 2–3 years are not suitable for infants, where the ideal healing time for an artery is 3 to 6 months. Poly p-dioxanone (PPDO) is an ideal alternative owing to its availability, FDA approval in clinics and suitable degradation time of 6 months.  But, braided PPDO fiber stents still have lower stiffness than standard self-expanding metal ones.

Researchers from China have come up with a novel design strategy to reinforce the mechanical properties of PPDO fibers by using an elastomeric polycaprolactone (PCL) coating which can serve as a binder at to improve the compression performance. This self-expandable, fiber-based, composite braided biodegradable stent (CBBS) made of PPDO and PCL was then assessed for its physical properties, changes in mechanical properties during degradation, etc and compared with the control, cobalt–chromium-based alloy self-expanding stents (WALLSTENTs/WSs). CBBSs delivered in sheaths post dilation exhibited similar mechanical properties as WSs.

In vitro degradation studies showed that CBBSs post-dilation retained effective mechanical support and stent weight (almost 90%) for at least 16 weeks, which is adequate for arterial healing. These results corroborate with the hydrolysis mechanisms involved in degradation of PDDO, the main component and with in vivo histopathological evaluation.

Lastly, the stents were implanted in porcine models without resulting in any evidence of complications such as implant migration, thrombosis, dissection or aneurism. The mechanical performance of CBBS was also not worse than metallic stents in vivo. Angiographic analysis revealed vessel stenosis and an inflammatory response (intima proliferation) at 4 months due to hydrolysis induced degradation of the stent. But this inflammation was resolved at 12 months due to the complete degradation of CBBSs unlike the WSs. When different diameters of WSs were compared, the ones in oversized common iliac arteries exhibited higher luminal gain initially but there was stenosis and vascular injury compared to normal-sized abdominal aortas in the mid-term follow-up period

All the results combined demonstrate the advantages of these novel composite braided degradable stents over the standard metallic ones in terms of mechanical strength and appropriate degradation rate.
