TL;DR: In this article, the authors evaluated the quality attributes of fresh-cut ‘Golden Delicious’ apples as affected by the combined application of a pulsed light treatment (12 J/cm 2 ) and a gellan-gum based (0.5% w/v) edible coating enriched with apple fiber.
Abstract: Pulsed light (PL) has received considerable attention during the last years as a non-thermal method for the superficial decontamination of fresh foods. The aim of the present study was to evaluate the quality attributes of fresh-cut ‘Golden Delicious’ apples as affected by the combined application of a pulsed light treatment (12 J/cm 2 ) and a gellan-gum based (0.5% w/v) edible coating enriched with apple fiber. Changes in color, firmness, antioxidant capacity, microbial growth and sensory attributes were determined during 14 days of storage at 4 °C. The combined application of coating and PL treatment retarded the microbiological deterioration of fresh-cut apples and maintained the sensory attribute scores above the rejection limits after prolonged storage. Incorporation of fiber in the coating formulation did not curb the sensory acceptability of apple cubes. Results show that the use of a gellan-gum based coating incorporating apple fiber followed by the application of a PL treatment significantly reduced softening and browning of apple pieces through storage. Our results reveal that PL treatments applied to gellan-coated fresh-cut apples can be used to decontaminate the cut fruit surface without dramatically affecting its fresh-like quality attributes, thus conferring prebiotic potential and contributing to their shelf-life extension.

TL;DR: Overall, the wildfire simulations showed very slight changes in flame length, while other outputs such as burn probability and fire size increased significantly in the second future period (2041-2070), especially in the southern portion of the study area.
Abstract: We used simulation modeling to assess potential climate change impacts on wildfire exposure
in Italy and Corsica (France). Weather data were obtained from a regional climate model
for the period 1981–2070 using the IPCC A1B emissions scenario. Wildfire simulations were
performed with the minimum travel time fire spread algorithm using predicted fuel moisture,
wind speed, and wind direction to simulate expected changes in weather for three climatic periods
(1981–2010, 2011–2040, and 2041–2070). Overall, the wildfire simulations showed very
slight changes in flame length, while other outputs such as burn probability and fire size increased
significantly in the second future period (2041–2070), especially in the southern portion
of the study area. The projected changes fuel moisture could result in a lengthening of
the fire season for the entire study area. This work represents the first application in Europe
of a methodology based on high resolution (250 m) landscape wildfire modeling to assess potential
impacts of climate changes on wildfire exposure at a national scale. The findings can
provide information and support in wildfire management planning and fire risk mitigation
activities.

TL;DR: Results show that methionine supplementation in the diet specifically increases mitochondrial ROS production and mitochondrial DNA oxidative damage in rat liver mitochondria offering a plausible mechanism for its hepatotoxicity.
Abstract: Methionine restriction without energy restriction increases, like caloric restriction, maximum longevity in rodents. Previous studies have shown that methionine restriction strongly decreases mitochondrial reactive oxygen species (ROS) production and oxidative damage to mitochondrial DNA, lowers membrane unsaturation, and decreases five different markers of protein oxidation in rat heart and liver mitochondria. It is unknown whether methionine supplementation in the diet can induce opposite changes, which is also interesting because excessive dietary methionine is hepatotoxic and induces cardiovascular alterations. Because the detailed mechanisms of methionine-related hepatotoxicity and cardiovascular toxicity are poorly understood and today many Western human populations consume levels of dietary protein (and thus, methionine) 2-3.3 fold higher than the average adult requirement, in the present experiment we analyze the effect of a methionine supplemented diet on mitochondrial ROS production and oxidative damage in the rat liver and heart mitochondria. In this investigation male Wistar rats were fed either a L-methionine-supplemented (2.5 g/100 g) diet without changing any other dietary components or a control (0.86 g/100 g) diet for 7 weeks. It was found that methionine supplementation increased mitochondrial ROS generation and percent free radical leak in rat liver mitochondria but not in rat heart. In agreement with these data oxidative damage to mitochondrial DNA increased only in rat liver, but no changes were observed in five different markers of protein oxidation in both organs. The content of mitochondrial respiratory chain complexes and AIF (apoptosis inducing factor) did not change after the dietary supplementation while fatty acid unsaturation decreased. Methionine, S-AdenosylMethionine and S-AdenosylHomocysteine concentration increased in both organs in the supplemented group. These results show that methionine supplementation in the diet specifically increases mitochondrial ROS production and mitochondrial DNA oxidative damage in rat liver mitochondria offering a plausible mechanism for its hepatotoxicity.
