WASHINGTON, May 18, 2021 — The COVID-19 pandemic has reinforced the pressing need to mitigate a fast-developing virus as well as antibiotic-resistant bacteria that are growing at alarming rates worldwide. Photodynamic therapy (PDT), or using light to...

Researchers at the University of Arkansas have developed a new nano drug candidate that kills triple negative breast cancer cells. Triple negative breast cancer is one of the most aggressive and fatal types of breast cancer....
by CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences The pancreas is an abdominal organ that produces digestive enzymes as well as hormones that regulate blood sugar levels. This hormone-producing function is localized to the islets of Langerhans, which constitute clusters of different endocrine cell types. Among those are beta cells,...
UNIVERSITY OF SHEFFIELD PDT does not always kill cells deep within a cancerous tumour, allowing tumours to grow back again. The new compound uses penetrating infrared light to damage cells directly and potentially improve the success rate of PDT Researchers at the University of Sheffield have synthesized a new compound which could improve the success...
Photodynamic therapy is often used to treat brain tumors because of its specificity—it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light....
