Carbon nanotube sheets to control stem cell differentiation and in vivo thrombin detection on the cover of Issue 6

On the covers this issue we have articles from Tai Hyun Park et al and Quyen Nguyen et al.

Tai Hyun Park and colleagues have used multi-walled carbon nanotube sheets as a matrix to control the differentiation and direction of stem cell growth into neural cells.  The MWCNTs directed the growth pattern of axons, and could open up new avenues for tissue and stem cell regeneration with regenerative medicine applications.

Integr. Biol., 2012, 4, 587-594
DOI: 10.1039/C2IB20017A

Our other cover article is from Quyen Nguyen and team, which included Nobel Laureate Roger Tsein, who have developed an imaging probe which can be used in vivo to detect thrombin in plagues.  They hope that the sensitive probe could eventually be used clinically to detect and diagnose atherosclerosis non-invasively, in a similar way to tumour detection by MRI.

DOI: 10.1039/C2IB00161F

Also in this issue we have HOT articles on understanding the ability of T-cells to stop at a site of infection and inducing cellular remodelling in mechanotransduction processes.

Struggling for acceptance? Top ten tips to get published

Ever wondered what makes a successful submission? A little preparation and some simple changes may make all the difference. Harp Minhas, Editor of Integrative Biology, shares his top ten tips for getting published:

1. Ensure your work has novelty and advances existing knowledge

  • This is the main criterion for publication in most journals

2. Provide a clear statement of novelty/impact

  • A lack of clarity about the relevance of your work could mean rejection

3. Provide a cover letter

  • The cover letter should include a summary of the work, a novelty statement (with possible implications or applications) and a statement of article type, e.g., review, paper, communication, etc.

4. Read and follow the Guidelines for Authors

  • Ensure your work is appropriate for the journal of your choice, sometimes the Guidelines for Authors are out of date so look at the journal content –  does it match your paper?

5. Perform a thorough literature search

  • References can tell Editors & Reviewers a lot about your knowledge of the field, make sure you have included all the relevant references to previously published works

6. Keep the language simple; short sentences

  • No matter what your native language is, short simple sentences help to maintain clarity and simplicity in explanation

7. Proof read before submission

  • Many small and minor errors are frustrating for reviewers as they read and assess your work, get a friend or colleague to read before submission

8. Write a clear, logical and concise story

  • The relevant sections of the paper should follow in a clear and logical manner, stick to the facts and do not over-claim the novelty/advances

9. On revision, address all the reviewer comments

  • Make sure you address ALL the reviewer comments, both in your responses and within the revised manuscript. It is OK to disagree with reviewers as long as you justify and explain why in your responses

10. If rejected, learn from the experience

  • Try to learn from negative publishing experiences, and try to improve for your next submission accordingly

The above list is not intended to give you all the information you will require to write papers, but may help set you upon the right path and could be helpful as a check list when preparing your work for submission to a journal. Many other factors are also important, for example, reading the Ethical Guidelines is essential if you are presenting experiments that involve animals; as is the declaration of in-press papers, if these are not declared up front, they will inevitably lead to delays in the publication of your work.

Organs-in-chips and the role of metabolism in heat stress responses on the cover of Issue 5

Organs-on-chipsThe articles featured on the cover of this month’s issue are from Andries D. van der Meer and Albert van den Berg and Jenny Gu et al.

Andries D. van der Meer and Albert van den Berg have reviewed the current progress in realistic in vitro tissue models: organs-on-chips.  The review covers recent developments and looks to the future at how organs-on-chips can make an impact on biological research.

Organs-on-chips: breaking the in vitro impasse
Andries D. van der Meer and Albert van den Berg
DOI: 10.1039/C2IB00176D

On a completely different subject, Jenny Gu and colleagues have looked at the mechanism of metabolism response to chronic heat stress in seagrass.  Their study suggests that adaptive mechanisms are involved through metabolic pathways to dampen the impacts of heat stress.

Identifying core features of adaptive metabolic mechanisms for chronic heat stress attenuation contributing to systems robustness
Jenny Gu, Katrin Weber, Elisabeth Klemp, Gidon Winters, Susanne U. Franssen, Isabell Wienpahl, Ann-Kathrin Huylmans, Karsten Zecher, Thorsten B. H. Reusch, Erich Bornberg-Bauer and Andreas P. M. Weber
DOI: 10.1039/C2IB00109H

Also in this issue are several hot articles on laser ablation for studying the mechanical properties of cytoskeletons, modelling of in vitro cell-free translation and the antioxidant benefits of red wine.

In vivo fluorescence imaging of atherosclerotic plaques

Quyen Nguyen and colleagues at the University of California have developed a probe that can be used to study thrombin activity in coagulation and atherosclerosis.

The probe was used in vivo to image atherosclerotic plaques in living mice. The fluorescent probe is based on an activatable cell penetrating peptide (ACPP) that incorporates a peptide sequence from the proteinase activated receptor 1. The probe is preferentially cleaved by thrombin (cleavage can be blocked using thrombin inhibitors), and this fluorescent cleavage product builds up at the site of atherosclerotic lesions. The fluorescence intensity varies depending on the severity of the plaque and the histologic grade of the aorta.

The probe was also used with human atheroma specimens ex vivo, and the retention of the fluorescent cleavage product was 63% higher than that found when using a control ACPP.

The team hope that probes like this could eventually be used to deliver MRI contrast agents to atherosclerotic plaques to enable non-invasive detection of conditions by magnetic resonance imaging.
