Test For Mad Cow Disease Is Here

...linical symptoms of prion disease. PMCA uses sound waves to vastly accelerate the process that prions use to convert normal proteins to misshapen infectious forms. Successive rounds of PMCA led to the discovery of prions in the blood of 16 of the 18 infected hamsters. No prions were found in blood sample...

T-waves to sweep over imaging technology

...tween infrared light and microwave radiation. The waves have already invited research in a multitude of diverse sectors such as the semiconductor materials, medicine, manufacturing, space, and defense industries. T-ray applications that could enable the label-free characterization of genetic material; det...

Understanding The Role Of Olfaction In Taste

...ng, a technique in which magnetic fields and radio waves detect increased blood flow to brain areas, which reflects increased activity. They used four odorants: chocolate for the food odour, and lavender for the non-food. They also chose two odorant chemicals - butanol and farnesol - to test a theory that ...

Have You Ever Wondered How We Perceive Different Sounds?

...vibrations that enter the ear in the form of sound waves into chemical signals, which they then direct to the brain. It is surprising to know that some species, including birds, are capable of re-growing hair cells. However mammals lack the ability to naturally regenerate hair cells. Thus individuals bor...

Outpatient Treatment Possible For Patients with Uterine Fibroid Tumors

Reducing The Risk Of Death In Sickle Cell Disease

...oppler echocardiography, which is a test that uses waves to see the heart. Researchers say 32 of the patients suffered from pulmonary hypertension.During the study period, researchers say 20 percent of the patients with pulmonary hypertension died and all but two of the patients without the condition survi...

Pill might be able to reduce the damage loud noise does to your hearing

...ch convert the mechanical energy of incoming sound waves into nerve messages to the brain. As hair cells die off, hearing erodes permanently. So it makes sense to try to build up the ear's antioxidant defenses as a preventive step, and as a fast treatment after noise exposure. Antioxidants should work bes...

Ultrasound may mean end to classic stethoscope

...orking and see if there is a problem. Ultrasonic waves and their echoes produce images of organs and systems inside the body. The ultrasound procedure is commonly used during pregnancy to check on the health of the baby or in tests to measure blood flow through the heart. Ultrasound has generally been ...

New combined therapy for Knee Joint pain

...s for the knee. In physiotherapy, electro magnetic waves from short wave diathermy and vibrations from the ultrasound machine remove the osteophytes from the joint. By doing isotonic, and isometric exercises we can increase the muscle tone. By the special manipulations we can increase the joint space and e...

Handheld ECG: stethoscope of the future

...ng standard echocardiography exams which use sound waves to provide moving pictures of the heart.In the past few years, miniaturisation has reduced these echocardiography systems to the size of a laptop computer. For their study, the Duke researchers recruited Duke second-year medical residents and cardio...

Possibility Of Treatment For Permanent Hearing Loss

...e to damage to the pathway through which the sound waves travel from the hair cells of the inner ear to the auditory nerves. The probable causes of this may be age, disease, infections, tumor or stroke. RNAi: RNA interference is a technique of gene silencing that is used to study the effect of absence o...

Studies On Hearing Loss Discovers New Causes

The probable causes of this may be age, disease, infections, tumor or stroke. Diabetes: Diabetes affects the population in terms of affecting the metabolism of blood glucose and i...

Being Obese Increases Ones Risk Of A wrong Diagnosis During Medical Imaging

...ibute this difficultly to the fact that ultrasound waves must penetrate through body tissue to produce an accurate image reading, and this becomes more difficult with heavier people. Thus researchers say manufacturers need to think about design changes and technological advancements to obtain quality imagi...

New Treatment For Tendonitis

... tendonitis syndromes. Specialists say the shock waves inhibit pain in the nerve endings and increase blood flow, promoting healing. Specialists also say It's a safe non-invasive procedure and is comfortable for the patient, and is also well-tolerated....

Testing for blood sugar levels made easier

...o obtain images of tissues. It uses infrared light waves that reflect off the internal structures within tissues to send back a picture and information about the tissue, in this case, including blood sugar levels. A pilot study of OCT was done on 15 healthy volunteers when images of the left forearm were ...

Microwave radiation has no hazards

Breakthrough in eye treatment

...robe, thinner than a strand of hair, applies radio waves at points around the cornea. The radio energy shrinks the tissue, increasing the curve of the cornea and correcting far-sightedness. “The whole procedure is done in the edge of the window, not in the center of the part that you look through for qual...

Microscopic lens monitors heart problems

...low monitor. It allows the focussing of ultrasonic waves from an outside generator onto the walls of the artery. The waves can measure how the blood is flowing and so give a very early indication of any problems that might ...
