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.

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.

Coated gold nanoparticles for drug delivery

In work that could at the same time impact the delivery of drugs and explain a biological mystery, MIT engineers have created the first synthetic nanoparticles that can penetrate a cell without poking a hole in its protective membrane and killing it.

New perspective on coronary disease thanks to ultrasound

Compared to other techniques, Intravascular Ultrasound (IVUS) is much better at monitoring the increase or decrease of atherosclerosis in the coronary arteries. Can the method even be used to predict the odds of a heart attack or other cardiovascular event? Studies indicate this may be the case, states Professor Clemens von Birgelen in his inaugural address at the University of Twente.

A magnetically contolled camera pill

Images from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus.
