Abstract Aims
The present work reports on one of the first attempts to use biofilm‐forming cyanobacteria for biomass and lipid production.
Methods and ResultsThree isolates of filamentous cyanobacteria wereobtained from biofilms at different Italian sites and characterized by a polyphasic approach, involving microscopic observations, ecology and genetic diversity (studying the 16S rRNA gene). The isolates were grown in batch systems and in a semi‐continuous flow incubator, specifically designedfor biofilms development. Culture system affected biomass and lipid production, but did not influence the fatty acid profile. The composition of fatty acids was mainly palmitic acid (>50%) and less amounts of other saturated and monounsaturated fatty acids. Only two isolates containedtwo polyunsaturated fatty acids.
ConclusionsData obtained from the flow‐lane incubator system would support a more economical and sustainable use of the benthic microorganisms for biomass production. The produced lipids contained fatty acids suitable for a high quality biodiesel production, showing high proportions of saturated and monounsaturated fatty acids.
Significance and Impact of StudyData seem promising whentaking into account thesavings in cost and time derived from easy procedures for biomass harvesting,especially when being ableto obtain the co‐production of other valuable by‐products.

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

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
