In vivo imaging of hydrogen peroxide with chemiluminescent nanoparticles

Most people think of hydrogen peroxide as a topical germ killer, but the medicine cabinet staple is gaining steam in the medical community as an early indicator of disease in the body.

New nanoprobe imaging station helps study the distribution of elements in cells

Scientists suspect that iron accumulation plays a role in neurodegenerative processes such as Parkinson's disease, but its distribution in neurons has never been observed because of the lack of techniques to do so. Until today.

Fluorescence resonance energy transfer technology shows how cancer may take hold

A team, led by researchers at the Carnegie Institution,* has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated.

Viewing dye-packed vesicles causes them to explode

It's a long-standing question: Can just the act of observing an experiment affect the results, According to a new study by Rockefeller University scientists, if the experiment uses a fluorescent dye called acridine orange, the answer is a resounding yes."

Scientists capture first optical images of carbon nanotubes inside a living organism

Using fruit flies, the researchers confirmed that a technique developed at Rice -- near-infrared fluorescent imaging -- was capable of detecting DNA-sized nanotubes inside living fruit flies.

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.

Scientists isolate stem cells in womb tissue

Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.

Nanoparticle drug delivery shows promise for the future of brain tumour therapy

A nanoparticle drug delivery system designed for brain tumour therapy has shown promising tumour cell selectivity in a novel cell culture model devised by scientists at The University of Nottingham. The project, conducted jointly by the Schools of Pharmacy, Biomedical Sciences and Human Development, will be featured in the September issue of the Experimental Biology and Medicine.
