Legions of nanorobots target cancerous tumors with precision
- Details
- Category: Research
Researchers from Polytechnique Montréal, Université de Montréal and McGill University have just achieved a spectacular breakthrough in cancer research. They have developed new nanorobotic agents capable of navigating through the bloodstream to administer a drug with precision by specifically targeting the active cancerous cells of tumours.
A new method cuts the cost of drug-building chemicals
- Details
- Category: Research
EPFL (École polytechnique fédérale de Lausanne) scientists design a new method to cheaply produce some of the most important chemical compounds in the pharmaceutical industry - the amines. The amines are one of the most important classes of chemical compounds today. Amines that contain a ring-like structure - called an "aryl" group - are used widely in pharmaceuticals, such as the top-selling drugs Abilify, Crestor, Gleevec, and Lidoderm.
Why is breast cancer common but heart cancer rare?

- Category: Research
Malignant cancers strike certain organs, such as the colon or breast, more often than others. In an Opinion publishing August 9 in Trends in Cancer, researchers propose that this vulnerability in some organs may be due to natural selection. Humans can tolerate tumors in large or paired organs more easily than in small, critical organs,
Outdated assessment of treatment response makes good cancer drugs look bad

Tumor shrinkage is not the only measure of a successful anti-cancer therapy. A University of Colorado Cancer Center article published in the journal Frontiers in Oncology describes a promising alternative: metabolic imaging. Tumors rush their metabolism to grow and proliferate.
Loophole for cancer cells
- Details
- Category: Research
Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant areas of the body. To do so, they have to pass through the walls of small blood vessels.
Asthma pill could reduce symptoms in severe sufferers

- Category: Research
The first new asthma pill for nearly 20 years has the power to significantly reduce the severity of the condition, a study led by the University of Leicester has found. The research was funded by Novartis Pharmaceuticals, National Institute for Health Research (NIHR) and the EU (AirPROM), and is described by the lead researcher as "a game changer for future treatment of asthma."
Berry wine, minus the alcohol, may offer help for those with diabetes
