Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...

Researchers develop a plant-based thermotherapy patch

A team of researchers at Tampere University, Finland, has developed a biodegradable, transparent, flexible and fast-acting thermotherapy patch from plant leaves. The patch is compatible with flexible electronic applications. ...

Stem cell sheets harvested in just two days

Stem cells are cell factories that constantly divide themselves to create new cells. Implanting stem cells in damaged organs can regenerate new tissues. Cell sheet engineering, which allows stem cells to be transplanted into ...

Microneedles for therapeutic gene delivery

There is great potential in gene therapy for treating certain types of cancer and genetic defects, immunological diseases, wounds and infections. The therapies work by delivering genes into the patients' cells, which then ...

A hydrogel that could help repair damaged nerves

Injuries to peripheral nerves—tissues that transmit bioelectrical signals from the brain to the rest of the body—often result in chronic pain, neurologic disorders, paralysis or disability. Now, researchers have developed ...

Nanoparticles can turn off genes in bone marrow cells

Using specialized nanoparticles, MIT engineers have developed a way to turn off specific genes in cells of the bone marrow, which play an important role in producing blood cells. These particles could be tailored to help ...

Nanomotors as probes to sense cancer environment

An interdisciplinary team of researchers from the Indian Institute of Science (IISc) has used a 3-D tumor model and magnetically driven nanomotors to probe the microenvironment of cancer cells. The team consists of researchers ...

Secure nano-carrier delivers medications directly to cells

Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers at the Technical University ...
