Pregnancy may protect against bladder cancer

Female mice that had never become pregnant had approximately 15 times as much cancer in their bladders as their counterparts that had become pregnant, according to new findings by investigators at the University of Rochester Medical Center. Their work appears online as a rapid communication in the journal Urology.

Quantum dots stop RNA interference in living cells

More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Automated magnetic resonance imaging technique assists in earlier Alzheimer's diagnosis

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

Looking into our bodies with state-of-the-art equipment

The University of Bristol is already world-famous for its biomedical research, but following a £2.3 million investment in newly refurbished labs, it will be able to advance techniques that look in even greater detail at what's going on in our bodies.

Early detection of Alzheimer's in the pipeline

A boost of $1.6 million for new research into Alzheimer's Disease for Australian scientists means that the early detection of the disease could well be in the pipeline.

Individualized therapies for non-Hodgkin's lymphoma identified with PET

Positron emission tomography (PET) could be an important tool for identifying non-Hodgkin's lymphoma patients who are likely to respond well to treatment with 90 ibritumomab tiuxetan (IT)-the first radioimmunotherapy treatment approved for use by the U.S. Food and Drug Administration, said researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

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.

ExpIND process speeds Alzheimer's drug research

Researchers are actively cutting the time and cost it normally takes to develop radiopharmaceuticals by taking advantage of "Exploratory Investigational New Drug" (ExpIND), an FDA-sanctioned procedure that enhances post-discovery drug development while observing scientific and patient safety standards.

Gene radiotherapy system shows promise for fighting treatment-resistant cancer cells

A gene radiotherapy system that detects and treats cancer cells that are resistant to traditional forms of chemotherapy and radiation showed success in the laboratory and could eventually prove beneficial for cancer patients, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

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.

Nuclear medicine imaging test could aid children suffering from reflux disease

A nuclear medicine imaging test was used to confirm that children with respiratory problems may be more likely to develop gastroesophageal reflux disease, according to researchers at Society of Nuclear Medicine's 55th Annual Meeting.

Unique brain maps to assist surgery and research

Researchers from the Howard Florey Institute in Melbourne are developing new technology to create individualised brain maps that will revolutionise diagnosis of disease and enhance the accuracy of brain surgery.

Transfer of learning traced to areas of the brain

Practice makes perfect, but a question that still remains a mystery is why it is so difficult to transfer learning from a trained to an untrained task? Why are we no better at remembering faces when we have been training our memory for words? Scientists at Umea University and Karolinska Institutet in Sweden now show in the journal Science that the answer lies in the brain areas activated by each task.

High-content screening as a universal tool for fingerprinting of vytotoxicity of nanoparticles

As researchers develop an ever-expanding toolkit of nanoparticles for use as drug and imaging agent delivery vehicles, there is a growing need to understand how a given nanoparticle's physical and chemical properties affect biological activity and toxicity.

Cancer-detecting nanoparticles

Magnetic resonance imaging (MRI) can be a doctor's best friend for detecting a tumor in the body without resorting to surgery. MRI scans use pulses of magnetic waves and gauge the return signals to identify different types of tissue in the body, distinguishing bone from muscle, fluids from solids, and so on.

Did you ever wonder why it is so difficult to part with your stuff?

A new study reveals fascinating insights into the specific neuropsychological mechanisms that are linked with the potential loss of possessions.

People with tune deafness able to detect a wrong note unconsciously

People with tune deafness aren't able to tell when a musician accidentally strikes the wrong note in a song, but their brains know the difference. Researchers from the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health, have found that people with tune deafness, an auditory processing disorder in which a person with normal hearing has trouble distinguishing notes in a melody, are able to detect a wrong note unconsciously.

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.
