Growing a blood vessel in a week

Growing a blood vessel in a week

The technology for creating new tissues from stem cells has taken a giant leap forward. Three tablespoons of blood are all that is needed to grow a brand new blood vessel in just seven days. Continue reading

In orbit or on Earth, implantable device will be commanded to release therapeutic drugs remotely

In orbit or on Earth, implantable device will be commanded to release therapeutic drugs remotely

Houston Methodist Research Institute scientists will receive about $1.25 million from the Center for the Advancement of Science in Space to develop an implantable device that delivers therapeutic drugs at a rate guided by remote control. Continue reading

Designer ‘barrel’ proteins created

Designer ‘barrel’ proteins created

Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport of oxygen in blood Continue reading

Paper-based synthetic gene networks could enable rapid detection of ebola and other viruses

Paper-based synthetic gene networks could enable rapid detection of ebola and other viruses

Synthetic gene networks hold great potential for broad biotechnology and medical applications, but so far they have been limited to the lab. A study published by Cell Press October 23rd in the journal Cell reveals a new method for using engineered gene circuits beyond the lab, allowing researchers to safely activate the cell-free, paper-based system by simply adding water Continue reading

Fast modeling of cancer mutations

Fast modeling of cancer mutations

Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. MIT researchers have now developed a new way to model the effects of these genetic mutations in mice Continue reading

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Tumor laterality (left-side vs. right-side) does not impact overall survival in breast cancer patients treated with breast-conserving surgery and adjuvant external beam radiation therapy, according to a study published in the October 1, 2014 issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of the American Society for Radiation Oncology (ASTRO). Studies have shown that breast cancer patients treated with radiation therapy have improved local-regional recurrence, and breast cancer-specific survival after breast-conserving surgery and overall survival (OS) after mastectomy Continue reading

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

Cellular self-destruct program has deep roots throughout evolution

Cellular self-destruct program has deep roots throughout evolution

In what seems like a counter-intuitive move against survival, within animals, some cells are fated to die from the triggering of an elaborate cell death program, known as apoptosis. Now, Sakamaki et. al., have honed in on understanding the evolution of caspase-8, a key cell death initiator molecule that was first identified in humans Continue reading
