Researchers have taken technology from makers of mobile phones and other consumer electronics and used it to grow 3D tissue. Scientists at the Draper Laboratory and the Massachusetts Institute of Technology (MIT) have created a prototype using an automated "layer-by-layer" assembly method -...
"Stitch-Free" Surgical 'Laser Welding' Of Tissue In Intestinal Surgery Improved
A new "solder" for laser welding of tissue during surgical operations has the potential to produce stronger seals and expand use of this alternative to conventional sutures and stapling in intestinal surgery...
Doses of medicine 100,000 times smaller than the diameter of a human hair prevent the tissue damage associated with atherosclerosis and other chronic diseases in mice. As part of a National Institutes of Health-sponsored project led by Zahi Fayad, PhD, of the Icahn School of Medicine at Mount...
An international research team has created unique photoluminescent nanoparticles that shine clearly through more than 3 centimeters of biological tissue -- a depth that makes them a promising tool for deep-tissue optical bioimaging. Though optical imaging is a robust and inexpensive technique...
When Facebook introduced a feature that enables people to register to become organ and tissue donors, thousands did so, dwarfing any previous donation initiative, write Blair L. Sadler and Alfred M. Sadler, Jr., in a commentary in Bioethics Forum, the blog of the Hastings Center Report, which...
A team of Harvard University have developed a cyborg tissue material that is a literal mesh of nanoscale electronics and cells, able to support cell growth while at the same time monitoring biological activities at the cellular level. More »
Researchers interested in determining the direct effects of a high saturated fat and high cholesterol (HFHC) diet on implanted fetal hippocampal tissues have found that in middle-aged laboratory rats the HFHC diet elevated microglial activation and reduced neuronal development. While the...
According to a study published in the journal Neurosurgery, using a new device called mechanical tissue resuscitation (MTR) to prevent cell death has been demonstrated to reduce the size and extent of damaged tissue caused by traumatic brain injury. The finding was made by researchers at Wake...
For the first time, US scientists have shown that HIV-fighting cells engineered from human stem cells can suppress the virus in living human tissue in mice. The team, from UCLA in Los Angeles, California, had already shown in principle that it was possible to create cells that seek out and...
Scientists have discovered how cells detect tissue damage and modify their repair properties accordingly. The findings, published in the journal Developmental Cell, could open up new opportunities for improving tissue repair in patients following illness or surgery. The Wellcome Trust-funded...
Research on Mt. Everest climbers is adding to the evidence that an amino acid called leucine - found in foods, dietary supplements, energy bars and other products - may help people burn fat during periods of food restriction, such as climbing at high altitude, while keeping their muscle tissue...
Neurosurgeons at the Krembil Neuroscience Centre, Toronto Western Hospital, have for the first time, initiated the restoration of lost brain tissue through brain bypass surgery in patients where blood flow to the brain is impaired by cerebrovascular disease. The study, which involved 29...
...from auto claim? let say the van that caused the accident was a company van driven by an employee of that company. the driver is 100% at fault. the company has $100000 policy on van.
Minority organ donations have more than doubled since the institution of grassroots awareness and education programs, according to a new retrospective study published in the May issue of the Journal of the American College of Surgeons. In 2010, the percentage of minority donors is expected to...
A group of "color-coded" laboratory mice are providing researchers with a novel way of tracking T-cells, enabling them to visualize and monitor the cellular immune responses of transplanted tissue in real time. The new imaging system is described in the June issue of Nature Medicine, which is...
There's currently no reliable tool to help prosthetic developers fit artificial limbs without ensuing discomfort or pain, or tell medical personnel when bed-ridden patients need to be moved to avoid bedsores and other problems. But help is now on the way. Prof. Amit Gefen of Tel Aviv...
The U.S. Food and Drug Administration approved a second test to screen blood, tissue and organ donors for a blood-borne parasite, Trypanosoma cruzi (T. cruzi), that causes Chagas disease, a serious and potentially fatal parasitic infection. The test, called Abbott Prism Chagas [Trypanosoma...
Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key cellular mechanism that guides embryonic heart tissue formation - a process which, if disrupted, can lead to a number of common congenital heart defects. Heart tissue forms in two...
