KIF1A‐Mediated Axonal Transport of Netrin‐1 in iPSC‐Derived Human Forebrain Neurons

Cytoskeleton, EarlyView.
ABSTRACT Netrin‐1 is a secreted laminin‐like protein that functions as a guidance cue for axon pathfinding in development. Netrin‐1 also modulates synapse formation in developing neurons and long‐term potentiation in mature neurons. Netrin‐1 is expressed in human neurons; however, its intracellular distribution and trafficking have not been assessed ...

A Control Strategy With Hybrid Compressor Modeling for Electric Vehicle CO2 Heat Pump Systems

Energy Science &Engineering, EarlyView.
A hybrid PSO‐BP compressor sub‐model is developed and embedded in a MATLAB/Simscape physical model of a transcritical CO2 heat pump system for electric vehicles. Based on this high‐fidelity platform, a phased variable‐PTC cooperative control strategy is proposed and evaluated.

Urinary and Faecal Amino‐Acids as Biomarkers for Colorectal Neoplasia in Lynch Syndrome—A Prospective Longitudinal Study

International Journal of Cancer, EarlyView.
ABSTRACT In Lynch syndrome, colonoscopy surveillance for colorectal cancer (CRC) is burdensome and post‐colonoscopy CRCs still occur. Unlike the faecal immunochemical test (FIT), gut metabolomic alterations including amino‐acids have shown potential as non‐invasive biomarkers for detecting both advanced and non‐advanced sporadic colorectal neoplasia ...

Growth and survival of spore forming Bacillus cereus in human milk exposed to different processing, and storage conditions

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Human milk (HM) is the preferred nutrition for all infants, including preterm and low‐birth‐weight infants, but it may still pose infectious risks even after pasteurization. Data on the behavior of Bacillus cereus in HM are limited. We therefore investigated the growth and survival of B.

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

Reconsidering how to dry orthodox seeds for improved ex situ conservation outcomes

PLANTS, PEOPLE, PLANET, EarlyView.
Ex situ seed conservation is an essential tool in our efforts to conserve wild and cultivated plant diversity, as mentioned in the Global Strategy for Plant Conservation and the Sustainable Development Goals. While there are established standards which seed banks follow, it is important that we continue to evaluate protocols and optimize processes ...
