DNA :: Where broken DNA is repaired

Ionizing radiation, toxic chemicals, and other agents continually damage the body’s DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. Intricate DNA repair mechanisms in the cells’ nuclei are constantly working to fix what’s broken, but whether the repair work happens “on the road” ? right where the damage occurs ? or “in the shop” ? at specific regions of the nucleus ? is an unanswered question.

Asthma :: ESRF lightsource helps tailoring new treatments against asthma

Asthma affects 300 million people worldwide and, according to World Health Organization, it killed 255 000 people in 2005. Asthma attacks are caused by an acute inflammatory reaction in the airways, a reaction that is largely due to actions of LTC4 synthase (an enzyme which catalyzes a synthesis process). For this reason asthma medicines often aim to block the downstream effects of LTC4 synthase.

MRI :: New high-resolution MRI machine comes to MIT

Last May, MIT acquired its first 3 Tesla Siemens MRI machine for noninvasive imaging of the human brain, located in the Martinos Imaging Center at the McGovern Institute.

Gene :: Live broadcasts

A new receptor gene has been discovered that could help scientists learn more about events taking place in situations that are usually subjected to barriers, such as fetal development or those occurring within the central nervous system.

Healthcare :: The future of medicine – Insert chip, cure disease?

Imagine a chip, strategically placed in the brain, that could prevent epileptic seizures or allow someone who has lost a limb to control an artificial arm just by thinking about it.

Ultrasound :: Tool for clearer ultrasound images

University of Virginia Engineering School Associate Professor William F. Walker and Research Associate Francesco Viola have developed a new tool ? an advanced imaging algorithm ? that is, quite literally, transforming the way we see things.

Asthma :: Crystal structure enables tailoring of pharmaceuticals against asthma

Researchers at Karolinska Institutet in Sweden have managed to elucidate the crystal structure of a human membrane protein ? LTC4 synthase ? which has a major influence on the development of asthma.

Health Insurance :: $35 billion for SCHIP reauthorization

Cindy Mann, executive director of the Center for Children and Families, Georgetown University issued the following statement on the release of the Senate Finance Committee chairman’ s proposal to renew the State Children’s Health Insurance Program (SCHIP):

Imaging :: Smaller is better for head and neck imaging

MiniCAT, a flat-panel-display-based (FPD) imaging system, yields head and neck images that are superior to those from much larger and bulkier computed tomography (CT) scanners.

Breast Imaging :: 3D breast imaging using gammas and x rays

Scientists at Duke University combine the best aspects of x-ray computed tomography (CT) scanning with single photon emission computed tomography (SPECT), which is the single-gamma-ray counterpart of positron emission tomography (PET) scans, to obtain both anatomical and functional information using a single comfortable gantry.
