Autopulse Would Reduce the Mortality Rates in Rural Victoria

...due to heart attack in the rural areas. It is a mechanical heart compressor and is found id to more effective than the manual compressors. The ambulance in the rural areas are fitted with these which costs about $20,000 and three were sent to Geelong and two each to Bendigo and Ballarat. The AutoPulse squeez...

Early Nitric Oxide Treatment Can Help Low Birth Weight Preemies

...of brain injury in premature newborns who required mechanical ventilation after birth, when given in the first 48 hours after birth,” Kinsella said. “We are optimistic this therapy could prevent long-term developmental and neurological problems in many of these children. The remarkable effects of protecting aga...

Too Much of Air in the Lungs Results in VILI

...lining, Bates said. At that point, doctors provide mechanical ventilation in the intensive care unit until the body heals itself. Bates explains the difficulty of treating the injured lung this way: ‘Imagine you have two balloons which you fill by pumping in air. Now imagine you have only one balloon, and you m...

Heart disease and strokes connected to a motor protein mechanism

...A, which uses chemical energy and converts it into mechanical energy. SecA is present only in bacteria and is not found in humans. SecA uses mechanical energy to secrete toxins and other harmful proteins to the exterior of the bacterium cell. Once a ...

Scientists Uncover The Secret Behind The Speed In Nerve cells Conduction

...h nerve cells, we've known that SNAREs provide the mechanical energy for membrane fusion, and another protein called synaptotagmin is the actuator," McNew said. "We also knew there was a chemical brake in the system, something that held the pre-positioned vesicle in check, but poised for release. These new stud...

A boon to the paralyzed -Brain Gate Neural Interface System

...mpulses. These impulses enable the user to operate mechanical devices with the help of a computer cursor. A report appearing in the July 13 issue of Nature includes the first published findings from an ongoing clinical trial of the Brain Gate Neural Interface System, a brain-computer interface device in the ...

Researchers Beginning to Identify Genetic Culprits of Arthritis

...ed before the disease even appears, preventing the mechanical grinding of bone from starting. Physicians could preemptively prescribe pharmaceuticals known to slow cartilage degeneration, and researchers could develop new pharmaceuticals to interrupt the disease process. (Source: Newswise)...

Research into Blindness Cure Goes Digital

...mplanting such an electronic device is to act as a mechanical retina that could "fool" the brain into thinking that the eye is still working. He said, "Blindness is often caused by the light cells at the back of the eye dying off, but by implanting a microelectronic device into the eye, we hope we will be abl...

Solitons Could Power Molecular Electronics, Artificial Muscles

...st in a soliton," Li said. The soliton's quantum mechanical properties -- including these newly discovered energy states -- are important because they affect how the particle carries a charge through organic materials such as conducting polymers at the molecular level. "These extra electronic states will ha...

Bone Marrow Cells Aid In Heart Repair

...g death." Despite advances in surgical procedures, mechanical assistance devices, drug therapy, and organ transplantation, more than half of patients with congestive heart failure die within five years of initial diagnosis. "Cardiovascular diseases are the most important cause of mortality in Canada and the w...

Teeth Reformation could be Possible with Ultrasound Technology

...iencing dental root resorption, a common effect of mechanical or chemical injury to dental tissue caused by diseases and endocrine disturbances. Mechanical injury from wearing orthodontic braces causes progressive root resorption, limiting the duration that braces can be worn. This new device will work to count...

Manual vs. Automated Chest Compression After Cardiac Arrest

...t compressions led to the development of automated mechanical chest compression devices. The load-distributing band (LDB) is a circumferential chest compression device with an electrically activated constricting band on a short backboard and has been approved by the Food and Drug Administration for use in attem...

Alternative to Open Heart Surgery

...eart disease//. Hence scientists have engineered a mechanical heart pump to help patients suffering from heart disease. The pump is only 4mm wide and 10cm long and is mounted on a stent and fed on a deflated balloon through an incision in the groin into the upper aorta which caries blood from the heart. On the ...

Octarms for robots for better grasping of objects

...Initially the robots could not do this and rely on mechanical gripping jaws. They were not good at grabbing or holding large or irregularly shaped objects. But now these tentacle-like manipulators are more nimble and flexible. They are called Octarms as they are similar to an octopus's limb. The project call...

Bicycle-Powered Portable Water Filter System For Disaster Zones

...d the unit, consisting of a bicycle coupled with a mechanical pump and a membrane module to filter the water. Believed to be the world's first, NTU experts said it is an improvement on the hand-cranked model made for Indonesia's tsunami-stricken Aceh Province in January last year. As an aftermath of the Dec...
