Abstract
PLA MPs are prepared via a novel and toxic‐chemical‐free fabrication route using ethyl lactate, a green solvent and FDA‐approved aroma. MPs are obtained by a solution jet break‐up and solvent displacement method. Adjusting flow parameters allows the tuning of MPs size between 60 and 180 µm, with reduced polydispersity. Morphological analysis shows microporous particles with Janus‐like surface. A fluorophore is successfully loaded into the MPs during their formation step. This versatile green solvent‐based procedure is proven to be suitable for drug encapsulation and delivery applications. The method may be extended to different droplet generation techniques.
<!--Unmatched element: w:blockFixed-->Ethyl lactate, a non‐toxic solvent, is used to obtain polylactide microparticles. Spherical microparticles with reduced size polydispersity are prepared via solution jet atomization/droplet solidification in a non‐solvent bath. Microparticles with interesting Janus surface roughness distribution and microporous interior morphology are loaded with rhodamine B.

Cancer risks for MLH1 and MSH2 mutation carriers
ABSTRACT We studied 17,576 members of 166 MLH1 and 224 MSH2 mutation‐carrying families from the Colon Cancer Family Registry. Average cumulative risks of colorectal cancer (CRC), endometrial cancer (EC) and other cancers for carriers were estimated using modified segregation analysis co ... more
Scope Flavonoids have well‐known antioxidant, anti‐inflammatory, and anti‐cancer activities. Isoflavone genistein is considered a potent antioxidant agent against oxidative stress. Although several mechanisms have been proposed, a clear antioxidant mechanism of genistein is still remain ... more
Abstract People can get oral cancers from UV (290‐400 nm) exposures. Besides high outdoor UV exposures, high indoor UV exposures to oral tissues can occur when consumers use UV‐emitting tanning devices to either tan or whiten their teeth. We compared the carcinogenic risks of skin to or ... more
Marijuana use may increase risk of testicular cancer
A new study from the University of Southern California (USC) has found a link between recreational marijuana use and an increased risk of developing subtypes of testicular cancer that tend to carry a somewhat worse prognosis. Published in CANCER the findings suggest that the potential cance ... more
New Study into Bladder Regeneration Heralds Organ Replacement Treatment
Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also ... more
