Plant based derivatives that cure cancer are a plenty with scientists discover more of them with time. One on the list from a long time is Resveratrol, a compound found in grapes, peanuts and berries. But how does this compound fight with cancerous cells? A new study has now thrown some light on the exact mechanism of how derivatives from resveratrol acts on cancerous cells and kills them, in the process, letting the other healthier cells remain unharmed. This discover, the researchers claim, can help scientists in developing more efficient drugs that can fight cancer, a deadly disease.

But how do bacteria fight against tumours? The answer lies in the environment the tumour creates during its growth. A tumour, by definition, is a mass of cells that have divided in an uncontrolled, abnormal manner without respecting the normal boundaries. Bacteria are known to modulate our immune defence system and strengthen it to fight against tumour cells. Bacteria activate our immune systems and provide an environment for the production of T cells, a type of lymphocyte, that displays greater ability to specifically recognize and act against tumour cells.
The traditional Asian chewing package used in marriages for symbolising heavenly love, is no longer having its heavenly charm according to a new research. Areca nut, packed with betel leaves and slaked lime, is an important chewing dessert in many Asian cultures. Its usage to cure indigestion and impotence dates back to first century AD and it is still being consumed by around 700 million people in the tropics for its psychoactive and brain stimulating properties. However, studies have indicated that several chemical compounds present in areca nut are carcinogens and its usage has been linked to oral cancers. Now a new study points at a detailed pathway on how chewing areca nut causes a precancerous condition.
Tumors are often linked to cancer when they become malignant and start to spread. Doctors and researchers throughout the world are continuously seeking better ways to diagnose and treat tumors early on, thus preventing severe damage. In a rare interdisciplinary study, engineers from the Indian Institute of Science, Bangalore, have stepped up to help doctors in treating tumors. Prof. Radhakant Padhi from the Department of Aerospace Engineering and his team has designed an automation tool for slow and controlled drug release. It is an intelligent feedback algorithm that can be embedded in a micro-controller and effective in treating solid tumors with minimal side effects.
A team at IISc, Bangalore has successfully developed a novel technique to target and destroy cancer cells through multiple actions.
As a group of diseases, cancer affects over 7 lakh people every year in India alone and kills majority of those that are affected. Cancer occurs when normal cells go rogue – tweaking certain functions that makes it easier for the cancerous cells to multiply and invade normal tissues, thereby affecting the organs’ functions. The current treatment for cancer involves radiation, chemotherapy and occasionally surgery, all aimed at killing the cancerous cells. However, these therapies can, at times, be inaccurate, killing a large number of healthy cells too.
