Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

The Bionic Interface: Considering the Material Mediated Electrical Stimulation of Stem Cells

Advanced Materials, EarlyView.
Electrical stimulation directs stem cell fate in tissue engineering. Cellular responses are influenced by membrane properties, intrinsic cell state, material charge‐transport characteristics, and the applied electrical signal. Additionally, a material’s ability to inject, store, and redistribute charge further modulates these responses.

Association of Troponin, C-Reactive protein, Albumin and C-Reactive protein/Albumin Ratios with Mortality in Intensive Care Unit Patients with Community-acquired Pneumonia

Acta Medica Alanya
Aim: Parameters used to determine prognosis in community-acquired pneumonia (CAP) patients often have limited clinical value. This study aims to examine the efficacy of CRP, albumin, CRP/albumin ratio and troponin elevation in predicting 30-day mortality

Measurement of Troponin in Cardiomyopathies [PDF]

Cardiogenetics, 2016
Troponins are thin myofilament proteins that regulate the contraction of cardiac and skeletal muscle. The cardio-specific troponin I (TnI) and T (TnT) proteins are sensitive and specific biomarkers of myocardial injury which over the past twenty years have revolutionised the diagnosis and management of myocardial infarction.

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

Polybithiophene‐Based Molecularly Imprinted Polymers: A Comparative Mechanistic Study on Electrochemical Signal Transduction Approaches for Protein Detection

Advanced Sensor Research, EarlyView.
This study provides the first detailed comparison of the mechanisms behind differential pulse voltammetry and electrochemical impedance spectroscopy in electropolymerized molecularly imprinted polymer (MIP) sensing platforms. Using cystatin C as a model protein, it reveals how electron transfer processes generate signals and offers evidence‐based ...
