Toy Story Turns Bitter-Christmas Toys, No Music to the Ears!

...isiest were found to be toy guns, which included a mechanical toy machine gun, a plastic tommy gun and a cap gun. These toys were risky because they could result in immediate hearing loss. Experts have cautioned against extended exposure to any noise, in the range of 85dBA, which could certainly pose a big r...

Large Variations in Cost Has No Effect on Length of Stay or Mortality

...than one-quarter of the patients required invasive mechanical ventilation. The ICU mortality rate was 7.3 percent, and another 5.3 percent survived the ICU, but died before hospital discharge. Contrary to the researchers’ early expectations, survey data showed that intensivists had an accurate sense of the IC...

North Texas Surgeons Lead Robotically Assisted Laparoscopic Surgeries.

...robot often can provide better visuals, access and mechanical stamina, which makes an operation less-tiring for the surgeons, said Dr. Livingston. “For particular operations, the robot has an advantage,” Dr. Livingston said. “It’s a combination of access, depth perception and magnification that provides the a...

Highly-Concentrated Botulinum Preparation Can Result in Severe Illness

...eatment in an intensive care setting, provision of mechanical ventilation when indicated, and rapid administration of antitoxin (optimally within 12 hours of presentation) have been associated with improved clinical outcome. Suspected cases of botulism should be reported immediately to local health authorities ...

Computer-Driven System Reduces Patient Mechanical Ventilation Time Significantly

...en system can significantly reduce the duration of mechanical ventilation and length of stay in the intensive// ...nd the computerized system reduced the duration of mechanical ventilation from 12 days to 7.5 days and cut patients’ ICU stay from 15.5 days to 12 days. “The co...

Low Birth Weight Babies May Have Mental & Physical Problems

...prevention of white matter injury and the need for mechanical ventilation may be key to improving motor outcomes, whereas the prevention of intrauterine growth retardation (or perhaps impaired head growth) and white matter injury may be key to improving cognitive outcomes. Taken together, these findings suggest...

Researcher Develops Sensor to Detect E.coli

...ayer that generates voltage in response to applied mechanical stress. A voltage is applied to the ceramic layer, making it expand and contract, causing the glass sliver to vibrate. The sensor detects changes in the glass sliver’s resonate frequency (the point where vibration is the greatest) and uses this to ...

Bionic Women –No longer the Stuff of Science Fictio

... extending far beyond her shoulder, with wires and mechanical parts as well as some of the six motors, clearly visible. Her hand is covered with a flesh-colored sheath, and the fingers move awkwardly. The interface between the body and machine makes the new arm unique. Gregory Dumanian, a plastic surgeon, at...

As a result of these efforts, 135 organs were upgraded from poor to usable, making them eligible for transplantation. “A key strategy for increasing the number of usable ...

New System Monitors Tiny 'Earthquakes' in Bones to Prevent Fractures

...tor the integrity of bridges, other structures and mechanical parts like helicopter turbine blades. "I asked, why not use the same approach to study stress fractures?" Akkus said. Such a technology could help prevent serious stress fractures in racehorses and those who perform in situations that cause undue...

MRI Development Yields Breakthrough in Diagnosis of Liver Fibrosis

...s a modified form of MRI to obtain pictures of the mechanical waves passing through the organ. The imaging can be accomplished in as little as 20 seconds. The wave pictures are then processed to generate a quantitative image of tissue stiffness -- called an elastogram. Researchers compared results of the proc...

First Implantable artificial heart gets FDA’s approva

What does High-fiber Foods Really do?

...nd fibers that can't be completely digested, are a mechanical challenge for these cells.' However according to Dr McNeil and his colleague Dr. Katsuya Miyake this is an adaptive response and most of these cells repair this damage rapidly while at the same time excrete even more mucus, which provides a bit of ...

Adult stem cells are sensitive to responses from the environment

...es motors that, like our muscles, are based on the mechanical tension created by molecules of actin and myosin," Engler said. "When we deprive these stem cells of myosin, the cells do not respond to their physical environment, only their chemical environment." But, the physical microenvironment can change du...
