It is difficult to diagnose, study and treat cioliopathies, because it is difficult to examine cilia in molecular detail. Now researchers report that they have captured the highest-resolution images of human cilia ever, using a new approach.

A lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes, has been developed by researchers. The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. It may prove especially useful in remote areas and in cases where large numbers of samples need to be examined quickly.

It’s a sound that saves. A “real-time” radiation monitor that alerts by beeping in response to radiation exposure during cardiac-catheterization procedures significantly reduces the amount of exposure that medical workers receive, researchers found.

Neurosurgeons became the first in Southern California to implant a deep brain stimulator (DBS) in a patient with Parkinson’s disease using real-time 3-D magnetic resonance image (MRI) guidance.

A new technology has been developed that can assess the location and impact of a brain injury merely by tracking the eye movements of patients as they watch music videos for less than four minutes. The study suggests that the use of eye tracking technology may be a potential biological marker for assessing brain function and monitoring recovery for patients with brain injuries.

Although currently available diagnostic screening systems for breast are effective at detecting early signs of tumors, they are far from perfect, subjecting patients to ionizing radiation and sometimes inflicting discomfort on women who are undergoing screening because of the compression of the breast that is required to produce diagnostically useful images. New research suggests a better, cheaper, and safer way to look for the telltale signs of breast cancer may be with microwaves.

According to the American Academy of Otolaryngology, more than 37 million Americans suffer at least one bout of acute sinusitis per year making it the most common medical ailment. Otolaryngology is the medical specialization of ear, nose and throat (ENT) conditions. The story of one woman's struggle with the illness ends with a cure after years of suffering.

Cervical cancer is, in many ways, a shining example of how successful the war on cancer can be. Thanks largely to the advent of Pap smear screening, U.S. cervical cancer deaths decreased dramatically, by more than 60 percent, between 1955 and 1992. In the last two decades, better treatment outcomes and more powerful imaging techniques have steadily pushed 5-year survival rates ever higher. The latest weapons in modern medicine's arsenal are two new vaccines that were recently approved by the U.S. Food and Drug Administration for preventing this type of cancer altogether.

A five-minute functional MRI test can pick up neuronal dysfunction in HIV-positive individuals who don't yet exhibit cognitive decline, say neuroscientists and clinicians. The issue of neural dysfunction in the HIV-positive population is significant. "About half of people living with HIV are affected by HIV-associated neurocognitive disorders, or HAND, and we expect this condition will escalate as the current HIV-positive generation ages," says the study's senior investigator.

Magnetic resonance imaging has been used by researchers to reveal why young people with Type-2 diabetes develop heart damage. The study will randomly allocate patients to different treatment arms. The first group will receive optimal blood sugar lowering treatment and lifestyle advice. The second, a very low calorie diet and the third, moderate intensity exercise training. The research team hope that conducting MRI scans throughout this period will indicate whether early heart damage can be completely reversed.
