Study reveals why MRI brain images are so sensitive to the direction in which nerve fibres run

World-leading experts in Magnetic Resonance Imaging from The University of Nottingham's Sir Peter Mansfield Magnetic Resonance Centre have made a key discovery which could give the medical world a new tool for the improved diagnosis and monitoring of brain diseases like multiple sclerosis.

CTCtrap can capture circulating tumour cells in cancer patients

The 7.5 millilitres of blood contained in a standard sample tube is not nearly enough to detect circulating tumour cells (CTCs) in the blood of patients with metastatic breast cancer, prostate cancer, or colorectal cancer with a high enough degree of reliability. These CTCs are the cause of metastases in cancer patients. If they can be effectively characterized, it is possible to arrive at a prognosis and to determine the most effective course of treatment.

Scientists unravel physical properties of lung mucus

Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked. Previously unclear was the extent to which such nanoparticles are able to move through the lungs' mucus. Here, the research evidence was contradictory. Scientists could not explain why, in inhaled medication development, drug nanoparticles often simply got stuck in the mucus never making it to their target destination inside the lung cells.

New technique can manipulate and measure magnetic particles without contact

If you throw a ball underwater, you'll find that the smaller it is, the faster it moves: A larger cross-section greatly increases the water's resistance. Now, a team of MIT researchers has figured out a way to use this basic principle, on a microscopic scale, to carry out biomedical tests that could eventually lead to fast, compact and versatile medical-testing devices.

High in-utero magnetic field levels may increase risk of obese or overweight in childhood

In-utero exposure to relatively high magnetic field levels was associated with a 69 percent increased risk of being obese or overweight during childhood compared to lower in-utero magnetic field levels, according to a Kaiser Permanente study that appears in the current online version of Nature's Scientific Reports.

MEG-MRI combined device for mapping the human brain

Researchers at Aalto University in Finland have developed the world's first device designed for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain. The merging of these two technologies will produce unprecedented accuracy in locating brain electrical activity non-invasively.

New type of micromachine can penetrate tissue and overcome cellular barriers

Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed.

Apple iPad 2 can affect programmable shunt valve in children with hydrocephalus

Researchers at the University of Michigan have found that the Apple iPad 2 can interfere with settings of magnetically programmable shunt devices, which are often used to treat children with hydrocephalus.

New microfluidic device can sort cancer cells, particles

In life, we sort soiled laundry from clean; ripe fruit from rotten. Two Johns Hopkins engineers say they have found an easy way to use gravity or simple forces to similarly sort microscopic particles and bits of biological matter -- including circulating tumor cells.

Transcranial magnetic stimulation enhances visual abilities in healthy adults

Using transcranial magnetic stimulation (TMS), an international team led by researchers from the Centre de Recherche de l'Institut du Cerveau et de la Moelle Epinière (CNRS / Inserm / UPMC) has succeeded in enhancing the visual abilities of a group of healthy subjects.

New magnetic sensor might simplify measurement of brain activity

In future a new magnetic sensor the size of a sugar cube might simplify the measurement of brain activity. In the magnetically shielded room of Physikalisch-Technische Bundesanstalt the sensor has passed an important technical test: Spontaneous as well as stimulated magnetic fields of the brain were detected.

MIT researchers engineer new jet-injection system

MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths - an improvement over similar jet-injection systems that are now commercially available.

Studies of technological innovations presented at DDW annual meeting

Studies of technological innovations being presented for the first time at Digestive Disease Week- (DDW) showed increased accuracy coupled with decreased cost, time or invasiveness of gastrointestinal procedures. Use of a new high-definition colonoscope, for example, improved physician confidence in diagnosing small polyps, potentially reducing the amount of polyps sent for pathology analysis and the associated costs.

Scientists decipher structure of bacterial injection needles at atomic resolution

The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response.

New article describes design and properties of magnetoelectric composite materials

Up to now, the brain's magnetic field is measurable only under technical laboratory conditions. This technique is therefore not feasible in terms of the broader medical use, although it would be significant for diagnosing numerous conditions such as epilepsy and dementia, or even for improving therapies such as deep brain stimulation for treating Parkinson's disease.

Chip-scale NIST sensor successfully measures human brain activity

A miniature atom-based magnetic sensor developed by the National Institute of Standards and Technology (NIST) has passed an important research milestone by successfully measuring human brain activity. Experiments reported this week verify the sensor's potential for biomedical applications such as studying mental processes and advancing the understanding of neurological diseases.
