Chitin, the second most abundant polysaccharide in nature after cellulose, has been the subject of increasing interest in recent years, particularly in the aquaculture sector. This review focuses on the effects of chitin in aquafeed on growth, nutrient utilization, gut microbiome modulation, and the immune system of aquatic organisms. Data from the literature showed significant variability in response to chitin by species, wit...

Systems capable of disinfecting air and surfaces could reduce the risk of infectious diseases transmission. Aim: to evaluate the effectiveness of near-UV LED ceiling lamps, with a wavelength of 405 nm, in improving environmental hygiene. Between November and December 2020, we conducted an experimental study having a pre-post design in a kindergarten room in Siena where 4 ceiling lamps with 405 nm LED technology were installed....

Increasing temperatures in the US Midwest are projected to reduce maize yields because warmer temperatures hasten reproductive development and, as a result, shorten the grain fill period. However, there is widespread expectation that farmers will mitigate projected yield losses by planting longer season hybrids that lengthen the grain fill period. Here, we ask: (a) how current hybrid maturity length relates to thermal availabi...
