Wearable scanner opens new pathways in the study of brain function
23:39 March 14, 2011

U.S. scientists have developed a new miniature, wearable Positron Emission Tomography (PET) scanner which enables the simultaneous study of brain function and behavior in animals. PET scans are much like Computed Tomography (CT) scans and have helped uncover the molecular underpinnings of conditions like drug addiction, brain diseases such as dementia and they have been used in the medical imaging of cancers.

Academics from the University of Manchester have developed a process of creating working human muscle tissue from sea squirts. The research holds promise for the engineering of muscles, ligaments and nerves from cellulose which is usually found in plants and is the main component of paper and plant based textiles such as cotton and linen. The creation of muscle from scratch along with the ability to repair existing muscle has the potential to improve the lives of millions of people around the world. Read More
Disposable endoscopic camera is the size of a grain of salt

Tiny video cameras mounted on the end of long thin fiber optic cables, commonly known as endoscopes, have proven invaluable to doctors and researchers wishing to peer inside the human body. Endoscopes can be rather pricey, however, and like anything else that gets put inside peoples’ bodies, need to be sanitized after each use. A newly-developed type of endoscope is claimed to address those drawbacks by being so inexpensive to produce that it can be thrown away after each use. Not only that, but it also features what is likely the world’s smallest complete video camera, which is just one cubic millimeter in size. Read More

When a patient has an arrhythmia (an irregular heartbeat), cardiologists will often treat the disorder by inserting two tube-like catheters into the patient’s heart. The first catheter is used for mapping out the heart tissue, identifying the location of cells that are causing the arrhythmia. The second catheter, which has an electrode on the end, is then directed to those locations, where it kills the aberrant cells in a process known as ablation. Scientists have recently developed a single catheter with added stretchable electronics, however, that does both jobs in one step. Read More
Lasers create custom medical devices, and make suturing easier

If you remember the MASH episode where Hawkeye and BJ got the Korean fix-it guy to build them a one-of-a-kind vein clamp, then you will understand the importance of custom-designed surgical tools – surgery is definitely not a field in which people should just make do with the next-best thing. Unfortunately, the production of some types of instruments can be quite involved, meaning they can't always be created quickly or cheaply. At this month's MEDTEC Europe trade show, however, researchers from Germany's Fraunhofer Institute for Manufacturing Technology and Advanced Materials will be demonstrating new technology that uses a laser melting process to easily create pretty much any surgical instrument imaginable ... or so they claim.

miraDry promises long-term solution to excessive underarm sweating
22:30 February 28, 2011

For many people the problem of Primary Axillary Hyperhidrosis or excessive underarm sweating is a huge issue affecting their quality of life. This medical condition occurs when the sweat glands are overactive in creating more sweat than is needed to cool the body – sometimes four or five times more sweat than normal. Miramar Labs has developed a new solution to this problem in the form of the miraDry system – a treatment that uses microwave energy to deactivate the sweat glands in the underarm. Read More
New system offers more accurate blood pressure measurements

Traditionally, blood pressure is measured using the familiar inflatable cuff and stethoscope on the upper arm. While this method has sufficed for over a century, some people maintain that it is inaccurate – blood pressure in the arm is reportedly higher than at the heart, and not by a consistent, easily compensated-for amount. Because high blood pressure can cause the most damage at the heart and in the nearby brain, it would make sense to monitor it at the heart, too. That's just what a new device designed at the University of Leicester does ... in a roundabout way. Read More
Phrazer handheld communicator aims to break through the healthcare language barrier

With over 170 languages spoken in the U.S. alone, medical personnel attending an emergency or working in a busy hospital are no doubt often faced with communication problems when trying to dispense treatment. The Phrazer offers a possible solution to this problem. It is billed as the world's first multilingual communication system, where patients provide medical background information, symptoms or complaints with the help of a virtual onscreen doctor speaking in their own native tongue. This information is then summarized into a medical record compatible with all major EMR systems. Read More

Millions of people around the world are medicated with heparin, a blood thinner used for the treatment and prevention of blood clots. One of the ways in which doctors monitor the effectiveness of heparin is to look for a blood protein known as factor Xa in a patient’s bloodstream – the less factor Xa activity that is occurring, the better. Now, thanks to an enzyme obtained from fireflies, that protein may be easier than ever to detect. Read More

Australian scientists may have discovered a vital key to curing HIV and other immune related illnesses by boosting the body’s immune response. A team of researchers led by Dr. Marc Pellegrini from the Walter and Eliza Hall Institute, successfully cured a HIV-like infection from mice by boosting the function of cells vital to their immune system.
