New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results - literally shrinking the lab down to the size of a thumbnail.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Early detection of pancreatic cancer closer thanks to multifunctional nanoparticles

Pancreatic cancer has a devastatingly low survival rate (less than 5 percent after 5 years) because it is usually diagnosed at an advanced stage. The initial symptoms, such as pain, jaundice, or weight loss, often do not allow the disease to be caught early enough for surgery and chemotherapy to be effective.

Positron emission tomography scans may improve the accuracy of dementia diagnosis

A new study shows that the use of positron emission tomography (PET) scans may improve the accuracy of dementia diagnoses early in disease onset for more than one out of four patients. The results were presented at SNM's 56th Annual Meeting.

New imaging analysis method predicts brain tumor survival

As early as one week after beginning treatment for brain tumors, a new imaging analysis method was able to predict which patients would live longer, researchers from the University of Michigan Comprehensive Cancer Center have found.

Scientists use non-invasive approach to watch chemo drug working inside the living body in real time

For many cancer patients, chemotherapy can be worse than cancer itself.

Researchers refine breast cancer identification

Not all breast cancers are the same, and not all will have fatal consequences.

Molecular imaging enables earlier, individualized treatment of thyroid cancer

In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery.

Symptoms of fibromyalgia related to dysfunction in parts of brain where pain is processed

Using single photon emission computed tomography (SPECT), researchers in France were able to detect functional abnormalities in certain regions in the brains of patients diagnosed with fibromyalgia, reinforcing the idea that symptoms of the disorder are related to a dysfunction in those parts of the brain where pain is processed.

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.

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.

Molecular imaging helps follow the progression of Alzheimer's disease

In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years.

Noninvasive molecular imaging technology helps track stem cells in tumors

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting. This ability could lead to major advances in the use of stem cell therapies to treat cancer.

Radioimmunotherapy targeting viral antigens shows potential to treat or prevent viral cancers

A new study, presented at the Society of Nuclear Medicine's 55th Annual Meeting, shows that radioimmunotherapy (RIT) targeting viral antigens offers a novel option to treat-or even prevent-many viral cancers by targeting cancer cells expressing viral antigens or infected cells before they convert into malignancy.

Study recommends development of standards for pediatric doses in nuclear medicine

Results of a recent survey of 13 pediatric hospitals in North America show a lack of universally applied standards for administering radiopharmaceutical doses to children undergoing nuclear medicine examinations, according to an article in the June issue of The Journal of Nuclear Medicine.
