A portable live-cell imaging system with an invert-upright-convertible architecture and a mini-bioreactor for long-term simultaneous cell imaging, chemical sensing and electrophysiological recording
<p>Cell culture in-vitro is a well-known method to develop cell and disease models for studying physiologically relevant mechanisms and responses for various applications in life sciences. Conventional methods for instance, ...
In vitro characterization of arylhydrazones of active methylene derivatives
Arylhydrazones of active methylene compounds (AHAMCs) are potent chemotherapy agents for the cancer treatment. AHAMCs enhance the apoptotic cell death and antiproliferation properties in cancer cells. In this study, a ...
Saline Accelerates Oxime Reaction with Aldehyde and Keto Substrates at Physiological pH
We have discovered a simple and versatile reaction condition for oxime mediated bioconjugation reaction that could be adapted for both aldehyde and keto substrates. We found that saline accelerated the oxime kinetics in a ...
An Inductively Coupled Biodegradable Capacitive Pressure Sensor
A biodegradable inductively coupled pressure sensor is presented. Three sensors were fabricated using melt processed biodegradable polymers and electron-beam evaporated magnesium. All the sensors showed similar pressure ...
Simulation of the Readout Methods for Inductively Coupled High-Frequency Resonance Sensors
The readout methods for inductively coupled resonance sensors were simulated using a lumped element model. The purpose of the study was to analyze the readout methods at high frequencies where the self-resonance of the ...
Atrial fibrillation detection from wrist photoplethysmography data using artificial neural networks
Atrial fibrillation (AF) can be detected by analysis of the rhythm of heartbeats. The development of photoplethysmography (PPG) technology has enabled comfortable and unobtrusive physiological monitoring of heart rate with ...
Finite element mapping for efficient image reconstruction in rotational electrical impedance tomography
Electrical impedance tomography (EIT) is a label free harmless imaging method capable of imaging differences in electrical conductivity of a sample. In EIT, a low frequency current is injected into the sample, voltage ...
Tango™ wellness motivator for supporting permanent lifestyle change
We present a system designed for assisting people in obtaining healthier lifestyle. The system includes a monitoring device worn on the chest and a web portal that visualizes the measured parameters and provides the user ...
Effects of the Small Conductance Calcium-Activated Potassium Current (IsK) in Human Sinoatrial Node
A novel technique for analysis of postural information with wearable devices
These days, as many jobs involve sitting behind desks and working with computers for extended periods, more and more people are suffering from back problems. Maintenance of an appropriate posture may prevent future back ...
