Laser-irradiated Coating Augments Nonsurgical Treatment of Obesity
WASHINGTON, D.C., April 19, 2022 — A multi-institutional research team in South Korea has enhanced the existing functionality of appetite-suppressing implants in the stomach with photodynamic therapy, coating such an implant with light-activated dye that kills cells that produce ghrelin, known as the “hunger hormone.” The researchers used and coated intragastric satiety-inducing devices, or ISDs in the work. The researchers in the current work designed and introduced these implants in 2019. Appetite-suppressing
Modified Antibodies Boost Photodynamic Therapy’s Efficacy
COLLEGE STATION, Texas, May 25, 2021 — Adding antibodies to photodynamic therapies can bolster their efficacy, according to research conducted by Texas A&M University and the University of São Paulo. The work reviewed the existing approaches to photodynamic therapies and...
Photodynamic Therapy Can Help Treat Respiratory Infections
SÃO PAULO, Aug. 11, 2020 — Photodynamic therapy can help combat secondary infections in COVID-19 patients, according to researchers at the Optics and Photonics Research Center (CEPOF), which is supported by the São Paulo Research Foundation. The researchers advocate...
Photosensitizer Design Absorbs Low-Energy Light, Transfers Energy Efficiently
SAPPORO, Japan, Jan. 23, 2020 — Researchers at Hokkaido University, working with colleagues in Japan to develop a photosensitizer design that could use low-energy light effectively, developed a design that made the rare earth element europium (Eu) shine five times more brightly...
New Light-Activated Metal Compound Kills Cancer Energy Source
COVENTRY, England, Oct. 18, 2019 — A team led by University of Warwick researchers is using light to activate a cancer-killing compound that attacks a vital energy source in cancer cells. This technique could be used not only to treat cancer, but also to help reduce side effects of...
Photosensitizer Enhances The Anticancer Properties of an Antimalarial Drug
SINGAPORE, Sept. 26, 2017 — Scientists have shown that the anti-cancer properties of artemisinin, an anti-malarial drug that is also a promising alternative cancer treatment, could be enhanced potentially ten-fold when used with the photosensitizer aminolaevulinic acid (ALA)....
CEA-Leti Study Aims to Improve PDT
GRENOBLE, France, May 13, 2010 — CEA-Leti, a public research and technology company based in France, announced the launch of the Target-PDT project designed to increase the effectiveness of photodynamic therapy (PDT) for treating cancer by developing a novel nanocarrier-based...
Chirped Fiber Improves Pulse
BERLIN, Oct. 29, 2008 -- By introducing a radial chirp into a photonic crystal, researchers in Germany and Russia have developed a novel optical fiber that can transmit ultrashort light pulses with very little distortion over extended distances. The fiber could prove useful...
Urologists Study New Photosensitizer
Jan 14, 2005 — ROCHESTER, N.Y., Jan. 14 -- Urologists at the University of Rochester Medical Center's James P. Wilmot Cancer Center are joining an international clinical study of hexvix, a new photosensitizer -- a liquid dye inserted into the bladder -- to improve...
