Philadelphia Researchers Found A Novel Way To Fight Several Kind of Cancers

...e, express TK, and only then could we use the FIAU tracer to make the cells light up," Pomper says. "So we were hoping to find a way to turn latent Epstein-Barr virus on in these cancers, and use the thymidine kinase it then produces to enable us to see the virus-associated tumors with radiolabeled FIAU." ...

New Guidelines For Assessing Lymphoma Treatment

...ique that uses radioactivity emitted from injected tracer chemicals to measure and image biological activity. The most commonly used PET radiotracer is fluorodeoxyglucose (FDG), a radiolabeled form of glucose, which is consumed more avidly by tumors than by normal tissue. In contrast to conventional compu...

Novel Brain Scan to Diagnose Alzheimer's Disease

Chemotherapy causes mental fog

...at follows the progress of an injected radioactive tracer produces an image of the parts of the body in PET. The scans were used to follow the brain metabolism at resting state and the blood flow to their brains during short-term memory tests. Silverman said, "The findings suggest PET scans can be used t...

New Technique to Identify Respiratory Problems in Children

...tracer' gas called sulphur hexafluoride. This is a tracer and allows doctors to measure the efficiency of the lungs. Professor Janet Stocks and colleagues from the University College London, Institute of Child Health and Great Ormond St Hospital tested the new device on 40 pre-school children with cystic fi...

Nanotechnology Promises Huge Medical Benefits

...ification of biohazards and screen biomolecules by tracer systems. The development of nanostructure incorporated iridescent plastic films that change color when stretched is yet another focus of nanotechnology research. The systematic study, manipulation and modification of these nanometer size particles ...

Chest Pain Can Be Identified By New Tracer Chemical 30 Hours After Pain Relief

Smoking Hazardous To The Enzymes System In Lungs

... a group of smokers and non-smokers. They used a tracer chemical, which sends out signals to the scanner, ...'s disease. What is more, the smokers retained the tracer chemical in their bodies for much longer than the non-smokers. This suggests that maybe they respond...

RNA Nanotechnology To Rescue Cancer Patients In Future

...t is also important for the molecule to act like a tracer that can provide valuable information regarding the location and the outcome of treatment. Particles pass through cell membranes into the cell's interior, and the body has a hard time retaining particles smaller than 10 nanometers. But the tiny tria...

New Technique To Test Stem Cells That Heal The Heart

...hymal stem cells (MSCs) labeled with a radioactive tracer and magnetic resonance imaging (MRI) contrast agent to enhance image quality. Both the tracer and contrast agent are widely used in research and routine clinical practice. The internal distri...

Quitting Smoking Made Easy By Track Of New Chemical

Camera gives hope for detection of breast cancer

...phy, which involved the injection of a radioactive tracer chemical.// Scintimammography, is good at distinguishing between malignant and benign tumours, has been done on a standard gamma camera. The limitation of this kind of camera is that it cannot pick up small tumours within dense breast tissue. The H...

Effect of Osteosarcoma predicted by scans

... a radioactive, biologically chemical is used as a tracer to show the activity of a part of the body in 'real time'. This study showed how a form of glucose - FDG (fluorodeoxyglucose) - was taken up by the tumour. A group of 35 patients with osteosarcoma, aged between five and 40, took place in this trial...

Tracing oesophagal cancer

...search Campaign, have used a dye and a radioactive tracer to track the progress of the cancer cells through the lymph glands. This will help select the glands that should be removed. The research involved 40 people with oesophagal cancer - and in 90% of cases, the new diagnostic technique did indicate where...
