manufacturing plant within the body, generates elements of the vaccine, these are supplied continuously for some time."...
Blood test could detect heart attack early
..., says Stanton. The technology, which can identify tiny
blood proteins by their unique electrochemical fingerprint, is generally only available in research settings. That may change in the near future, as the technology becomes more affordable and more practical for use in clinical settings, such as emerg...
Myosin molecule walks like a person, experiment shows
...e Science Express Web site, on June 5. Myosin is a tiny
molecular motor that converts chemical energy into mechanical motion. While there are more than a dozen types of myosin (including myosin II the main protein responsible for muscle contractions), Selvin and his collaborators studied myosin V. "This...

but complex molecules that recognize, bind to and admit LDL cholesterol into cells. A deficiency in LDL receptors leads to a buildup of LDL in blood, causing heart attacks at a young age. Their groundbreaking research led to effective new drugs to tr...
Minimally invasive esophagectomy results in improved survival and shorter hospital stays
...through very small incisions and a laparoscope, or tiny
camera. Patients who are candidates for MIE undergo extensive preoperative evaluation involving laparoscopic staging, endoscopic ultrasound and CT scans to assess the extent of the disease. "Our study demonstrates that minimally invasive esophagecto...
Rice uses buckyballs to reinvent 'antibiotic of last resort'
... variant of vancomycin that contains buckyballs -- tiny
cage-shaped molecules of pure carbon -- could become the world's first targeted antibiotic, creating a new line of defense against bioweapons like anthrax. Vancomycin, which entered clinical service 40 years ago, is the antibiotic of last resort, giv...
Emory scientists present alternative for surgical biventricular resynchronization
...ecause it allows us to overcome that problem using tiny
incisions." He explains that one incision only 1/2 inch long and two to three pencil-sized holes are made in the chest wall under anesthesia. Then a special camera and small grasping tool are inserted to allow visualization and connection of the lea...
New biological sensors for detecting blood glucose developed by Hebrew University, U.S. Scientists
... of this type are likely to serve in the future as tiny
devices not only to sense glucose levels for diabetic patients, but also as implanted biofuel cells that would enable production of electrical energy from blood sugar to operate heart pacemakers, insulin pumps or prosthetic components....

New first-aid method could prevent brain damage in patients exposed to carbon monoxide
...en fires When carbon monoxide is inhaled--even in tiny
concentrations--it combines with the hemoglobin in the red blood cells to prevent the delivery of oxygen to the body This results in few symptoms until the poisoning is advanced Those suffering from carbon monoxide poisoning may initially complain ...
Tissue-engineered cells transmit electrical signals in animal hearts
... an electrical signal that begins in the atrium, a tiny
area of the heart's upper-right chamber. The signal then moves to the other chambers. Damage to the electrical pathway between the atrium and ventricles (the lower chambers) can result in complete heart block, a potentially fatal condition that can...
Engineering researchers are designing the ultimate fabrics, for casual or military wear

New technique lets doctors examine milk ducts for breast problems
... is caused by benign changes such as the growth of tiny
polyps, known as papillomas, in the ducts. Doctors traditionally treat the condition by surgically removing the ductal system that is releasing the fluid, but it often is difficult to locate the abnormal tissue within the breast. For example, ductog...
