Proposal for a non-adhesive single-cell culture technology for primary hepatocytes.

Unlabelled: Primary hepatocytes (PHs) are indispensable for studying liver function, drug screening, and regenerative medicine. However, freshly isolated PHs only survive for a few hours in non-adherent suspension culture. This study proposes treatment with PEG-GRGDS, a polymer-peptide conjugate comprising polyethylene glycol (PEG) and the pentapeptide sequence Gly-Arg-Gly-Asp-Ser (GRGDS), to sustain the viability of dispersed single PHs under non-adherent conditions.

Uncovering the impact of outliers on clusters' evolution in temporal data-sets: an empirical analysis.

This study investigates the impact of outliers on the evolution of clusters in temporal data-sets. Monitoring and tracing cluster transitions of temporal data sets allow us to observe how clusters evolve and change over time. By tracking the movement of data points between clusters, we can gain insights into the underlying patterns, trends, and dynamics of the data.

Layer-dependent Schottky contact at TaX-BY (X = S, Se, Te; Y = P, As, Sb) van der Waals interfaces.

The mechanical, thermal and dynamical stabilities, electronic structure, contact type, and height of the barrier at the interface of TaX (X = S, Se, Te) and BY (Y = P, As, Sb) metal-semiconductor (MS) contact are investigated first principles calculations. Binding energies, mechanical properties, phonon spectra and molecular dynamics (AIMD) simulations confirm the stabilities of these systems. TaX-BY (X = S, Se, Te; Y = P, As, Sb) MS van der Waals heterostructures (vdWHs) are found to be metal with a Schottky contact at the interface.

Acute sport-related concussion alters cardiac contribution to cerebral oxygenation during repeated squat stands.

Assessment of cerebral oxygenation during repeated squat stands following an acute sport-related concussion (SRC) has the potential to identify physiological changes following SRC. All varsity university athletes completed a pre-season assessment and 53 were followed up within 5-days of suffering an SRC. Of the 53 participants, 29 had continuous beat-to-beat blood pressure (BP; sampled at 200 hz) collected by finger photoplethysmography, and 53 had right prefrontal cortex oxygenation collected by near-infrared spectroscopy (NIRS; sampled at 10 hz).
