Intracellular Recordings with Electrodes

Electrophysiology is an invaluable technique for studying the electrical activity of neurons in the brain and has important clinical applications. The use of nanowire and nanotube intracellular electrode recording devices has improved the spatial resolution and sensitivity of electrophysiological techniques. However, intracellular recordings within thick tissues is limited by the length of the nanotube/nanowire electrode, […]

Death to Tumor Cells

  Researchers from the Karlsruhe Institute of Technology, Germany and University of Kiev, Ukraine have developed a new photodynamic substance that may be useful for attacking tumors. Photodynamic therapy typically involves using light to create free radicals out of oxygen. A special substance is delivered to the area of treatment and light is used to activate […]

Molecular Thermometers Made From DNA Strings

  At the University of Montreal scientists have created a DNA-based thermometer that is so tiny that it can be inserted into cells to read the temperature inside. The inspiration came from seeing naturally occurring molecules being used to sense the temperature in the biological world. Such molecules fold and unfold at specific temperatures and so […]

AsTris 1.0 Spinal Simulator

BioTras, a company out of McKinney, Texas, is unveiling its AsTris 1.0 spinal simulator for training clinicians how to perform needle placements for pain management applications. The device is essentially a representation of a human with transparent tissues so that the bones of the back and spine are clearly visible. Needles can be inserted into […]

FUJIFILM VisualSonics

FUJIFILM VisualSonics won FDA clearance to introduce the world’s first clinical ultra high frequency ultrasound system. The compatible transducers operate at frequencies up to 70 MHz, providing imaging details down to 30 micrometers. Typical ultrasounds go up to about 15 MHz, but while imaging resolution is significantly improved by the Vevo MD, the depth of […]

Accuryn Smart Urimeter

Potrero Medical, a San Francisco firm, landed FDA clearance for its Accuryn monitor that uses a sensor-equipped catheter to provide real time data on patient urine output, intra-abdominal pressure, and temperature. Filtering the intra-abdominal pressure data can provide the patient’s heart rate, respiratory rate, and relative stroke volume. The system features automatic clearing of the drain […]

Yoga Reduces Asthma

A new Cochrane Review, published in the Cochrane Library today, suggests that yoga may have a beneficial effect on symptoms and quality of life in people with asthma, but effects on lung function and medication use are uncertain. Asthma still continues to be a is a common chronic disease that affects nearly 300 million people […]

New Infrared Photodetector Means What?

A new shortwave-midwave-longwave infrared photodetector that has the ability to realize a three-color has just been developed by Northwestern University's Manijeh Razeghi and her team. With the new design, the devices can detect different infrared wavebands by simply varying the applied bias voltage. This could open up a range of potential applications, including infrared color […]

Understanding Dopamine Neurons

Princeton University researchers have found that dopamine -- a brain chemical involved in learning, motivation and many other functions -- also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease. To get a better idea of how the dopamine […]
