New light shed on atrial fibrillation after bypass surgery
..., this was the first study to actually capture the precise day of onset of atrial fibrillation and the postoperative complications. These data allowed the researchers to examine the relationship between the two, as well as the effect of recurrent atrial fibrillation on postoperative outcomes. The study was s...Jefferson scientists find how HIV causes dementia

While some have argued that covert orienting of attention and eye movements are independent of one another, other researchers have supported the so-called "premotor theory" of ...CAD proves to be viable option for second reading mammograms
...nd low in x-ray attenuation; however, CAD was very precise in detecting calcifications, said Dr. Slanetz. The radiologists missed two cases of faint calcifications that were detected by CAD. One cancer case was missed by both, said Dr. Slanetz. The recall rate (the chance a screening patient is called back...It's a gamble: Dopamine levels tied to uncertainty of rewards

... during emotional memory formation, the study used precise anatomical methods, which involved tracing of these regions on each subject's brain image. Thus, it was possible to precisely localize the signal coming from anatomically proximal brain regions. As expected, analysis of the behavioral data revealed...3D neutron-based medical imaging, 4D lung scans, and hitting a moving tumor
