Possible location of lung cancer genes found

...he investigators used high-resolution machinery to scan the cells' chromosomes in 115,000 locations. They found several areas that had already been identified as having copy-number errors, plus five new ones –– two where genes had been deleted, and three where they had been highly over-copied. The next ...

Brain damage can affect children who stop breathing

...body temperature. The researchers had used the MRI scan images to come to their findings. The research findings have noted that tissue injury happens in the brain when the patients of this disease do not breathe for even a small interval of time. This injury may prevent different parts of the brain from...

Virtual Colonoscopy May Be Better Than Real-time Colonoscopy

...thod, after the tumor is removed, doctors use a CT scan to create an image of the area. The doctors then instruct the computer to focus the treatment only on the area where the tumor was removed by using a series of beam angles. According to Dr. Vicini, 100 percent of the dose goes to about four centimete...

CT Scans Said to Accurately Detect Small Cancers

...rinary masses. Results of the study show the MDCTU scan detected 93 percent of urinary system cancers in the 65 patients studied. Researchers say MDCTU can spot numerous problems in the tiny vessels of the urine collection system and also detect bladder cancer and kidney stones. Intravenous pyelogram (I...

Humans Found To Have The Ability To Block Unwanted Memories

...hers used magnetic resonance imaging technology to scan participants’ brains during the second part of the experiment. Results of the study show participants remembered fewer words they actively tried to ignore than those they were told to remember. Researchers say these results suggest that the human br...
