Photocatalytic production of hydroxyl radicals by commercial TiO nanoparticles and phototoxic hazard identification.

Toxicology 2018 08 22;406-407:1-8. Epub 2018 May 22.

Guangdong Biocell Biotechnology, Ltd., Dongguan, Guangdong, 523888, China.

This study identifies the phototoxic potential of commercial titanium dioxide nanoparticles (TiO NPs) used in sunscreens and consumer products by employing a tiered testing approach comprising physicochemical, in vitro and ex vivo tests. Our results revealed that all the test samples of TiO NPs, varied in surface coating, crystallinity and primary particle size, produced hydroxyl radicals upon UVA photoexcitation as determined by electron spin resonance (ESR) spectroscopy. Their phototoxic potentials were assessed first by combining the validated 3T3 neutral red uptake phototoxicity test and red blood cell phototoxicity test and subsequently in ex vivo models of chick chorioallantoic membrane (CAM) and reconstructed human 3D skin model (H3D).

Systematic Effect for an Ultralong Cycle Lithium-Sulfur Battery.

Nano Lett 2015 Nov 30;15(11):7431-9. Epub 2015 Oct 30.

Beijing Key Laboratory of Environmental Science and Engineering, School of Material Science & Engineering, Beijing Institute of Technology , Beijing 100081, China.

Rechargeable lithium-sulfur (Li-S) batteries are attractive candidates for energy storage devices because they have five times the theoretical energy storage of state-of-the-art Li-ion batteries. The main problems plaguing Li-S batteries are poor cycle life and limited rate capability, caused by the insulating nature of S and the shuttle effect associated with the dissolution of intermediate lithium polysulfides. Here, we report the use of biocell-inspired polydopamine (PD) as a coating agent on both the cathode and separator to address these problems (the "systematic effects"). Read More

The impact of postoperative expansion initiation timing on breast expander capsular characteristics: a prospective combined clinical and scanning electron microscopy study.

Plast Reconstr Surg 2015 Apr;135(4):967-74

Montreal, Quebec, Canada From the Division of Plastic and Reconstructive Surgery, University of Montreal Hospital Center, and the Department of Chemical Engineering, École Polytechnique, Université de Montréal.

Background: In the first stage of expander-to-implant breast reconstruction, postoperative expansion is classically initiated at 10 to 14 days (conventional approach). The authors hypothesized that it may be beneficial to wait 6 weeks postoperatively before initiating serial expansion (delayed approach). Clinical and ultrastructural periprosthetic capsule analysis is first required before determining whether a delayed approach ultimately improves capsular tissue adherence and expansion process predictability.

Departments of Dermatology, Dongguk University Ilsan Hospital, Goyang 410-773.

Vitiligo is a pigmentary disorder induced by a loss of melanocytes. In addition to replacement of pure melanocytes, cocultures of melanocytes with keratinocytes have been used to improve the repigmentation outcome in vitiligo treatment. We previously identified by in vitro studies, that adipose-derived stem cells (ADSCs) could be a potential substitute for keratinocytes in cocultures with melanocytes. Read More

Biocell 2013 Apr;37(1):11-6

Harran University, Art and Science Faculty, Department of Biology, Osmanbey Campus, Sanliurfa, Turkey.

The cell cycle is a conserved process from yeast to mammals and focuses on mechanisms that regulate the timing and frequency of DNA replication and cell division. The temporal and spatial expression of the genes is tightly regulated to ensure accurate replication and transmission of DNA to daughter cells during the cycle. Although the genes involved in interphase are well studied, most of the genes which are involved in mitotic events still remain unidentified. Read More

Biofabrication 2013 Dec 6;5(4):045004. Epub 2013 Nov 6.

Centre for Rapid and Sustainable Product Development, Polytechnic Institute of Leiria (IPL), Leiria, Portugal.

Novel additive manufacturing processes are increasingly recognized as ideal techniques to produce 3D biodegradable structures with optimal pore size and spatial distribution, providing an adequate mechanical support for tissue regeneration while shaping in-growing tissues. With regard to the mechanical and biological performances of 3D scaffolds, pore size and geometry play a crucial role. In this study, a novel integrated automated system for the production and in vitro culture of 3D constructs, known as BioCell Printing, was used only to manufacture poly(ε-caprolactone) scaffolds for tissue engineering; the influence of pore size and shape on their mechanical and biological performances was investigated.

A likely role for a novel PH-domain containing protein, PEPP2, in connecting membrane and cytoskeleton.

Biocell 2012 Dec;36(3):127-32

Department of Biology, School of Life Science and Technology, Jinan University, Guangzhou, China.

PH domains (pleckstrin homology) are well known to bind membrane phosphoinositides with different specificities and direct PH domain-containing proteins to discrete subcellular apartments with assistances of alternative binding partners. PH domain-containing proteins are found to be involved in a wide range of cellular events, including signalling, cytoskeleton rearrangement and vesicular trafficking. Here we showed that a novel PH domain-containing protein, PEPP2, displayed moderate phosphoinositide binding specificity. Read More
