Important Features Of Natural Pores Copied By Man-made pores
2012-07-17 10:57:46

Inspired by nature, researchers design tiny, synthetic pores that mimic important features of cellular ion channels and other molecular channels Inspired by nature, an international research team has created synthetic pores that mimic the activity of cellular ion channels, which play a vital role in human health by severely restricting the types of materials allowed to enter cells. The pores the scientists built are permeable to potassium ions and water, but not to other ions such as...

Sophion and CreaCell announced today that the two companies successfully demonstrated the performances of HEK-hKir2.1 cells on QPatch HT. (PRWEB) July 12, 2012 Inward rectifier potassium channels of the Kir2 subfamily are important determinants of the electrical activity of cardiac cells, and mutations of the Kir2.1 channels are associated with familial atrial fibrillation, Andersen-Tawil syndrome and short-QT syndrome. Because human Kir2.1 is a relevant target in preclinical cardiac...

The number of children diagnosed with autism spectrum disorder (ASD) has recently increased to one in 100. New research published in BioMed Central's open access journal BMC Medicine demonstrates that EEG can distinguish between children with autism and neurotypical controls. Autistic children showed a reduction in short range connectivity indicating poor function of local brain networks, especially in the left hemisphere regions responsible for language. However these children had increased...

Findings Could Give Directors, Advertisers New Ways to Predict How Audiences Will Respond Visual and auditory stimuli that elicit high levels of engagement and emotional response can be linked to reliable patterns of brain activity, a team of researchers from The City College of New York and Columbia University reports. Their findings could lead to new ways for producers of films, television programs and commercials to predict what kinds of scenes their audiences will respond to....

A Cleveland Clinic study has detected significant changes in the electroencephalogram (EEG) brain activity patterns of patients receiving chemotherapy. The study may give scientific evidence of a condition commonly referred to as "chemobrain" — the fogginess that many patients experience while on chemotherapy. Patients with chemobrain often report short-term memory problems and difficulty concentrating. "The EEG study demonstrated a higher amplitude, or more brain activity in...

In 1619, the pioneering astronomer Johannes Kepler published Harmonices Mundi in which he analyzed data on the movement of planets and asserted that the laws of nature governing the movements of planets show features of harmonic relationships in music. In so doing, Kepler provided important support for the, then controversial, model of the universe proposed by Copernicus. In the latest issue of Biological Psychiatry, researchers at the University of California in San Diego suggest that...

Robot Reveals The Inner Workings Of Brain Cells

New method offers automated way to record electrical activity inside neurons in the living brain Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice...

Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another. New research at Washington University School of Medicine in St. Louis unveils some of the inner workings of certain channels involved in regulating electrical signals in nerve cells, relaxing muscle cells and “tuning” hair cells in the inner...

Researchers at the EPFL have discovered rules that relate the genes that a neuron switches on and off, to the shape of that neuron, its electrical properties and its location in the brain The discovery, using state-of-the-art informatics tools, increases the likelihood that it will be possible to predict much of the fundamental structure and function of the brain without having to measure every aspect of it. That in turn makes the Holy Grail of modelling the brain in silico–the goal...

Electrocardiography
2013-04-30 09:55:53

Electrocardiography, sometimes called ECG or EKG, is a measurement of the electrical activity of the heart as the linear process unfolds. With the use of electrodes that are attached to the skin, this non-invasive test can provide vast information as to the patient’s status. By leaving the electrodes attached, the patient’s status can be monitored over intervals of time and recorded on the device. This data can be sent electronically for consults about potential treatments without delay....

Electrooculography
2012-12-31 11:47:45

Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...
