Best Practices for Correctly Identifying Coronavirus by Transmission Electron Microscopy
Bullock et al., Kidney International. 2021.
https://pubmed.ncbi.nlm.nih.gov/33493525/
This paper provides strategies for identifying coronaviruses by transmission electron microscopy in ultrathin sections of tissues or tissue cultures. As illustrated by results in the literature, organ damage may be incorrectly attributed to the presence of virus, since images of coronavirus may resemble subcellular organelles. The paper also references numerous biochemical and imaging techniques to aid an investigator in avoiding pseudo positive identifications. Supported by ORIP (S10OD026776) and others.
A Pulsatile Release Platform Based on Photo-Induced Imine-Crosslinking Hydrogel Promotes Scarless Wound Healing
Zhang et al., Nature Communications. 2021.
https://pubmed.ncbi.nlm.nih.gov/33723267/
Skin wound healing is a dynamic and interactive process involving the collaborative efforts of growth factors, extracellular matrix (ECM), and different tissue and cell lineages. Although accumulating studies with a range of different model systems have increased our understanding of the cellular and molecular basis underlying skin scar formation, they have not been effectively translated to therapy. Development of effective therapeutic approaches for skin scar management is urgently needed. In this study, team of investigators devise a water-oil-water double emulsion strategy to encapsulate proteins within a photo-crosslinkable poly-lactic-co-glycolic acid (PLGA) shell, which can produce microcapsules with pulsatile drug release kinetics after administration. The results show that pulsatile release of the TGF-β inhibitor can accelerate skin wound closure while suppressing scarring in murine skin wounds and large animal preclinical models, suggesting that it could be an effective approach to achieve scarless wound healing in skin.
