A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses

Advanced Healthcare Materials, EarlyView.
This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Chamber‐Specific Decellularized Extracellular Matrices Differentially Modulate Cardiomyocyte Subtypes to Drive Engineered Heart Tissue Development and Function

Advanced Healthcare Materials, EarlyView.
Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Interaction of Sodium Dodecyl Sulfate with Polymers

Nippon kagaku zassi, 1962
ポリビニルピロリドン,ポリピニルアルコールまたはポリビニル硫酸ナトリウムがドデシル硫酸ナトリウムと共存する溶液について,イエロ一OBに対する可溶化能,粘度および電導度などを測定した。また,これらの溶液にさらにトルイジンブルーを加えて吸収スペクトルを測定した。ドデシル硫酸ナトリウムにポリピニルピロリドンが共存する溶液の性質はポリビニルアルコール,またはポリビニル硫酸ナトリウムが共存する溶液の性質と異なり,両者間にはいくつかの相違点が見いだされた。この差違の原因については,(1)高分子上へのドデシル硫酸ナトリウムの吸着状態が高分子により異なることによるもので,ポリビニルピロリドンにはドデシル硫酸ナトリウムがミセル的に吸着するのに対し,ポリビニルアルコールまたはポリビニル硫酸ナトリウムには離散的に吸着する,
