Fluorescent nanocrystals reveal regulated portals of entry into and between the cells of Hydra. [PDF]
PLoS ONE, 2009 Initially viewed as innovative carriers for biomedical applications, with unique photophysical properties and great versatility to be decorated at their surface with suitable molecules, nanoparticles can also play active roles in mediating biological ...

Electrical charge on ferroelectric nanocomposite membranes enhances SHED neural differentiation
Bioactive Materials, 2023 Stem cells from human exfoliated deciduous teeth (SHED) uniquely exhibit high proliferative and neurogenic potential. Charged biomaterials have been demonstrated to promote neural differentiation of stem cells, but the dose-response effect of electrical ...

Trypanosoma cruzi: cell charge distribution
Revista do Instituto de Medicina Tropical de São Paulo, 1985 Differences in cell charge between epimastigote and trypomastigote populations were compared in Y, Cl and Colombiana strains of T. cruzi. Trypomastigote populations were more homogenous in relation to cell charge than epimastigotes.

Positively bound: Remapping of Increased Positive Charge Drives SARS-CoV-2 Spike Evolution to Optimize its Binding to Cell Surface Receptors [PDF]
, 2022 The SARS-CoV-2 Omicron sub-lineage contains a significant number of mutations in the spike protein relative to earlier SARS-CoV-2 variants. Most notably, these mutations significantly increased the positive charge of the spike protein that is postulated ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Mechanisms for surface potential decay on fluorinated epoxy in high voltage DC applications [PDF]
, 2014 Epoxy resin has been extensively used for decades as an insulation material in high voltage transmission systems. However, this insulation material does suffer from bulk and surface charging when used as insulating spacer, mainly in high voltage DC ...

Effects of paclitaxel nanocrystals surface charge on cell internalization
European Journal of Pharmaceutical Sciences, 2016 In this study, we investigated the influence of paclitaxel nanocrystals (PTX-NC) surface charge on cell internalization and cell cytotoxicity. PTX-NCs were prepared using the nano-precipitation method. The surface-modified PTX-NCs were prepared using an absorption method with positively charged poly(allylamine hydrochloride) (PAH) and negatively ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
