FATTY ACID COULD KILL HUMAN CANCER CELLS

Researchers have demonstrated that a fatty acid called dihomogamma-linolenic acid, or DGLA, can kill human cancer cells. The study, published in Developmental Cell on July 10, found that DGLA can induce ferroptosis in an animal model and in actual human cancer cells. Ferroptosis is an iron-dependent type of cell death that was discovered in recent years and has become a focal point for disease research as it is closely related to many disease processes.

RESEARCHERS AT JOHN HOPKINS UNIVERSITY USE NANOPARTICLES TO TREAT MACULAR DEGENERATION

Wet age-related macular degeneration and a number of other eye diseases, including congenital conditions, are related to mutated genes that result in blood vessel abnormalities. These can be treated with gene therapy, but delivering genetic material has proven to be difficult when dealing with large gene sequences that are common in retinal conditions. Viruses have been the go-to vectors for delivering genes into the eye, but the immune system wants to fight them. Too often this results in poor efficacy…

Fidget spinners to detect utis via urine samples

More than half of all women experience at least one episode of urinary tract infection (UTI) in their lifetime, with men also facing increasing risks of infection as they age. Current detection of UTIs rely on patients reporting symptoms followed by a lab culture of the urine for known bacterial culprits, which typically takes a few days. However, doctors tend to prescribe antibiotics to suppress any suspect cases of UTI before they get the test results, contributing to the increasing…

30-minute urine test to measure levels of substances that can contribute to kidney stones

Researchers from Penn State and Stanford University have developed a 30-minute urine test to measure levels of substances that can contribute to kidney stone formation. The test could help patients to find out if they are prone to developing kidney stones or to monitor their progress in avoiding kidney stone formation through treatment or dietary changes. Kidney stones are accumulations of crystallized substances such as minerals and salts, and the stones can cause pain and blockages in the urinary system.…
