Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

Methamphetamine enters brain quickly and lingers

Using positron emission tomography (PET) to track tracer doses of methamphetamine in humans' brains, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory find that the addictive and long-lasting effects of this increasingly prevalent drug can be explained in part by its pharmacokinetics - the rate at which it enters and clears the brain, and its distribution.

Vulnerable plaque may be easier to detect through optical coherence tomography

Research results indicate that optical coherence tomography (OCT), a newly evolving imaging method, may be the best tool available to detect vulnerable plaque in coronary arteries. The findings will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

Nanotubes detect tumors and deliver high-potency punch

Researchers at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have found a new way to target cancer cells while leaving healthy cells untouched.

Gene variant boosts risk of fatty liver disease

Researchers at UT Southwestern Medical Center have found that individuals who carry a specific form of the gene PNPLA3 have more fat in their livers and a greater risk of developing liver inflammation.

New tool for early diagnosis of breast cancer

Scientists from Finland, Germany and the ESRF have developed a new X-ray technique for the early detection of breast cancer. This allows a 3D visualization of the breast with a high spatial resolution and is extremely sensitive to alterations in the tissue, such as those generated by cancer. This technique could be used in the next years in hospitals. It may help doctors to detect tumours with greater precision than is possible using current X-ray mammography.

Many colorectal cancer survivors do not receive recommended follow-up screening

A new analysis reveals that fewer than half of older patients successfully treated for colorectal cancer receive the recommended screening schedule to detect any recurrence of cancer.

Computed tomography provides anatomy - we need ischemia!

Cardiac computed tomography has revolutionized cardiac imaging in recent years by providing exquisitely detailed cardiac anatomy, including, but not limited to, coronary anatomy.

New molecular imaging techniques aim at detection of earliest steps of disease development

An emerging discipline of noninvasive cardiac imaging, molecular imaging, has evolved constantly in the last few years and is increasingly being translated from the preclinical to the clinical level.

Ongoing debate: The future of non-invasive cardiac imaging

Imaging has gained attention in many areas of medicine but its relevance and importance in clinical cardiology cannot be underestimated.

One night without sleep increases chemical dopamine in the human brain

Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep. However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.

Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

PET scans spot signs of early Alzheimer's

Scientists in Finland say a type of imaging technique known as positron emission tomography (PET) scanning may be a useful and non-invasive way of diagnosing the early stages of Alzheimer’s disease.

Markers in blood and spinal fluid, and a new imaging agent, show promise for early detection of Alzheimer's

With the continued aging of the population and the growing epidemic of Alzheimer's, early detection of the disease is crucial for risk assessment, testing new therapies, and eventual early intervention with better drugs, once they are developed. Four studies reported today at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008) in Chicago bring us closer to that goal of early detection by describing advances in biomarkers.

Oily fish protect Japanese men against clogged arteries

If you're fishing for ways to reduce the risk of heart disease, you might start with the seafood-rich diet typically served up in Japan. According to new research, a lifetime of eating tuna, sardines, salmon and other fish appears to protect Japanese men against clogged arteries, despite other cardiovascular risk factors.

PET-CT scanners detect secondary head and neck cancers

For patients with head and neck cancer, accurately determining how advanced the cancer is and detecting secondary cancers usually means undergoing numerous tests - until now.

Study shows promising results in deep brain stimulation for treatment-resistant depression

New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced continued and sustained improvement over time.

Researchers locate and image prostate cancer as it spreads to lymph nodes

Using an engineered common cold virus, UCLA researchers delivered a genetic payload to prostate cancer cells that allowed them, using Positron Emission Tomography (PET), to locate the diseased cells as they spread to the lymph nodes, the first place prostate cancer goes before invading other organs.

New 3-D object recognition and image processing technology to detect cancer

Technology which will make it possible to semi-automate the process for detecting cancerous tumours more precisely is being developed by academics at the University of Hertfordshire.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.
