This study shows that an important factor correlating

with growth variation is the duration of corneo-scleral tissue in organ culture. Interestingly, donor age was not correlated with limbal explant growth. J. Cell. Physiol. (C) 2012 Wiley Periodicals, Inc.”
“Multifunctional nanoparticles have been developed to overcome the conventional hurdles associated with the diagnosis and treatment of disease. However, there are often caveats involved with the development and clinical translation of multifunctional nanoparticles largely regarding the notion that additional functionality increases nanoparticle complexity. Here, we discuss two design concepts, a conventional approach, all-in-one’, and introduce the concept of one-for-all’ to suggest that multifunctionality does not necessarily result in Nutlin-3 order multicomponent complex nanoparticles. This review focuses on the design concepts of all-in-one and one-for-all with examples of each approach and a discussion on the implications for clinical translation.

“We report the efficient photoelectrocatalytic (PEC) reduction of Cr(VI) using TiO2 nanotubes (TNTs) as the photoanode and a large-area Ti mesh as the photocathode. Short-length TNTs (S-TNTs) selleck inhibitor show much greater PEC activity than

either long-length TNTs (L-TNTs) or sol-gel-prepared TiO2 film, due to the fact that the TNT structure is advantageous of trapping light energy over the thin-film structure and the S-TNTs enable the more efficient electron transfer into the substrate than L-TNTs. More importantly, increasing the surface area of the photocathode (Ti mesh) can greatly accelerate the PEC reduction of Cr(VI), presumably due to the increased number of the active reduction sites on the larger-surface Ti mesh. In the PEC reduction of Cr(VI), Cr(V) is identified as a

reaction intermediate using the electroparamagnetic resonance technique, whereby the process for the Cr(VI) evolution is proposed. The S-TNTs have been confirmed to be stable over many repetitive cycles of use, indicating their suitability for wide-scale use. (C) 2010 Elsevier B.V. All rights reserved.”
“Sources and sinks of methane, one of the most important greenhouse gases, have attracted intensive attention signaling pathway due to its role in global warming. We show that sea ice in the Arctic Ocean regulates methane level through two mechanisms, shielding of methane emission from the ocean, and consumption of methane. Using a static chamber technique, we estimated that the methane flux from under-ice water was 0.56 mg(CH4) m(-2) d(-1) on average in central Arctic Ocean, relatively higher than that in other oceans, indicating considerable methane storage in this region under sea ice. Average methane flux on under-ice water was higher than that above sea ice, which suggests that sea ice could limit methane emission.
