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.

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.

Prenatal nutrition and nutrition during childhood interact to alter puberty

A high-fat diet during pregnancy and nursing may lead to the child having an early onset of puberty and subsequent adulthood obesity, according to a new animal study. The results were presented Monday, June 16, at The Endocrine Society's 90th Annual Meeting in San Francisco.

Medicines derived from cannabis: A review of adverse events

Researchers at the McGill University Health Centre (MUHC), McGill University and the University of British Columbia (UBC) determined that medical use of cannabinoids do not cause an increase in serious adverse events, but are associated with an increase in some non-serious adverse events.

Computer predicts anti-cancer molecules

A new computer-based method of analyzing cellular activity has correctly predicted the anti-tumour activity of several molecules.

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.

Compound in grapes and red wine may help battle obesity

Resveratrol, a compound present in grapes and red wine, reduces the number of fat cells and may one day be used to treat or prevent obesity, according to a new study. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.

Discovery of mechanisms that direct cholinergic synapse assembly between neurons in vivo

Rapid information processing in the nervous system requires synapses, specialized contact sites between nerve cells and their targets. One particular synapse type, cholinergic, uses the chemical transmitter acetylcholine to communicate between nerve cells. Cholinergic synapses are essential for normal learning and memory, arousal, attention, and all autonomic (involuntary) nervous system functions.

Nanoparticles trigger built-in cell-death signal to overcome drug resistance

One of the most vexing problems in treating cancer is the propensity of tumors to develop resistance to a wide range of anticancer drugs. Over 70 percent of ovarian cancer patients, for example, have drug-resistant tumors at the time of their initial diagnosis, and virtually all patients who relapse have drug-resistant tumors.

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.

Nanoparticle delivers antisense agent to tumors

A multifunctional drug delivery system consisting of a lipid-based nanoparticle, a standard anticancer drug, and a short nucleic acid designed to augment the activity of that drug has demonstrated the ability to treat drug-resistant tumor cells.

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.

Human tumor nanoparticles induce apoptosis of pancreatic cancer cells

Using nanoparticles made from pieces of tumor cells, investigators from Aix-Marseille University in Marseille, France, have developed a new type of anticancer agent that appears to stop tumor cell growth and proliferation.
