Carbon nanotubes continue to show promise in battle against cancer

Carbon nanotubes, one of the original engineered nanomaterials, also may prove to be among the most versatile, as numerous teams of investigators continue to develop novel nanotube-based therapeutic and diagnostic tools. Over the past month, three new research papers have highlighted the potential of nanotubes as weapons against cancer.

Nanofluidic biopsy detects subtle changes in cancer cells

By taking two standard laboratory techniques - capillary electrophoresis and antibody-based protein detection - and shrinking them to the nanoscale, researchers at the Stanford University School of Medicine have created a new method for detecting miniscule changes in the levels of proteins associated with cancer.

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.

Computer-guided nanoparticle therapy destroys tumors

Gold nanoshells are among the most promising new nanoscale therapeutics being developed to kill tumors, acting as antennas that turn light energy into heat that cooks cancer to death. Now, a multi-institutional research team has shown that polymer-coated gold nanorods one-up their spherical counterparts, with a single dose completely destroying all tumors in a nonhuman animal model of human cancer.

Possible link between insulin glargine and cancer prompts urgent call for more research

The European Association for the Study of Diabetes (EASD) has made an urgent call for more research into a possible link between use of insulin glargine (an insulin analogue) and increased risk of cancer, following evidence from studies in Germany, Sweden and Scotland. However, until this further research becomes available, these experts are stressing that patients with diabetes taking Lantus should continue to do so, although some might wish to consider alternative types of insulin. The studies are reported in Diabetologia (the journal of EASD), edited by Professor Edwin Gale of the University of Bristol.

Electrothermally driven micropumps for medicine

In biomedicine and biotechnology the smallest, complex, compound sample quantities must be reliably processed. Microsystems with new mechanisms of action for pumping, filtering and separating will manage this task with great efficiency in the future.

Blood pressure cuff could help improve the success of kidney transplants

The first clinical trial funded by the new Efficacy and Mechanism Evaluation (EME) programme will investigate whether a simple procedure to activate one of the body's natural defence mechanisms improves the function of kidneys after transplantation. This research is funded by the Medical Research Council and managed by the National Institute for Health Research.

Scientists investigate health benefits of molecule associated with male sexual arousal

Medical scientists at the University of Leicester are investigating how signalling molecules known to control blood pressure and penile erection act to regulate brain function and which have potential for treatments of migraine, chronic pain, epilepsy and Alzheimer's disease.

Protein biochips

Biochips carrying thousands of DNA fragments are widely used for examining genetic material. Experts would also like to have biochips on which proteins are anchored. This requires a gel layer which can now be produced industrially.

Telehealth Solutions launches CardioPod for NHS Health Check

Telehealth Solutions has today launched the CardioPod, a system to facilitate the new NHS Health Check nationwide. The CardioPod will be installed in pharmacies and GP surgeries across England, allowing patients easy access to an NHS Health Check carried out by a trained professional, who will give expert advice on their cardiovascular risk score and what action they can take to reduce the risk of heart disease, stroke, type II diabetes and kidney disease.

New biomarker predicts brain tumor's response to cediranib therapy

A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib.

Microbial and maternal influences on allergic sensitization during childhood

When infected, the body has two types of immune defence to deploy - innate immunity and acquired immunity. In her dissertation, Shanie Saghafian Hedengren studies monocytes, a type of white blood corpuscles that are part of the innate immune system.

Migraines with aura in middle age associated with late-life brain lesions

Women who suffer from migraine headaches in middle age accompanied by neurological aura (visual disturbances, dizziness or numbness that can precede migraines) are more likely to have damage to brain tissue in the cerebellum later in life, according to a study by researchers at the National Institute on Aging (NIA) of the National Institutes of Health, the Uniformed Services University of the Health Sciences and the Icelandic Heart Association in Reykjavik.
