Artificial Urethral Sphincters can Help the Elderly

...lications include infection, tissue breakdown, and mechanical failure. Consequently there has been marked reluctance in using the device in the case of elders, particularly because of a possible lack of dexterity on the part of patients. But the Milwaukee study shows that even octogenarians can handle the dev...

Researchers Urge Regulators to Rethink Strategies for Soot Emission

...llution," said Robinson, an associate professor of mechanical engineering and engineering and public policy. "We need to take a holistic approach to regulating these sources that account for all emissions." Accounting for these new processes improves the predictions of the models federal and state governments u...

Sleep Well, Have a Healthy Heart !

...athetic drive, acute surges in blood pressure, and mechanical effects of intrathoracic pressure swings, have varying effects on myocardial oxygen supply and demand, particularly in the already compromised heart," said Sean M. Caples, DO, of the Mayo Clinic College of Medicine in Rochester, Minn., one of the aut...

More Americans Suffer from Vertebral Compression Fractures

...perts believe that pain relief is achieved through mechanical support and stability provided by the bone cement. A newer procedure, called kyphoplasty, involves an added procedure performed before the cement is injected into the vertebra. First, two small incisions are made and a probe is placed into the vert...

Airborne Infection Less in Naturally Ventilated Rooms

Stem Cell Transplants Explored as a Possible Treatment for Hearing Loss

... in the cochlea. It's these cells that convert the mechanical energy of sound into electrical impulses that are sent to the brain so that a chicken, a mouse or a human can hear. Chickens, like all birds, have the ability to spontaneously regenerate these hair cells, which explains why there are no deaf birds. ...

UC Davis Creates New Nanoparticles

Woven Cartilage

...old that the researchers have created had the same mechanical properties as native cartilage. In the near future, surgeons will be able to impregnate custom-designed scaffolds with cartilage-forming stem cells and chemicals that stimulate their growth and then implant them into patients during a single procedur...

New Inhaler is Child's Play

...balloon limiting the inhalation volume. A patented mechanical valve at the air inlet on the other side of the mouthpiece reduces the inhalation flow rate (limiting it to 150ml/s), allowing slow, controlled delivery of the therapeutic aerosol. As the drug is inhaled, the silicone balloon deflates, folding up ...

Communication in the ICU to Be Strengthened

... deciding whether life-sustaining measures such as mechanical ventilation should be continued or withdrawn. In half of these cases, the family conference proceeded under the customary ICU practice. In the other half, the physicians conducted the conferences in accordance with the VALUE guidelines. They also pro...

Low-Fat Peanut Flour Thickens More

...ntage of protein than peanuts. This is because the mechanical process of removing fatty oil from roasted peanuts leaves the flour low in fat, high in protein and fairly low in carbohydrates. PRI...

Sleeping Sickness Comes to India

.... However, that does not exclude another indirect, mechanical infection pathway, by way of blood-sucking insect for example. An insect vector is involved in transmission of both sleeping sickness and Chagas disease (3). Research continues aiming to unravel the transmission process and mechanisms by which the ...

Training Breathing Muscles Improves Swimmer's Performance

Robotically Assisted Colo-resection And Gastric Bypass Surgeries Are Becoming Popular

...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...

How Blood Flow Dictates Gene Expression

...day-old embryo. The researchers surmise that the mechanical stimulus of blood flowing in a vessel leads to the upregulation of Klf2, which either activates or represses genes that control smooth muscle tone, that is the caliber of the vessel. (Tone is governed by how much a muscle contracts or relaxes.) These...
