This literature review evaluates the absorption of methionine (Met) sources such as 2-hydroxy-4-methylthiobutyric acid (HMTBa), its calcium salts (HMTBa-Ca), and DL-methionine (DL-Met) by focusing on the state of knowledge regarding the absorption mechanism, experimental methodology, and factors affecting their absorption. The 2 Met sources differ in mechanism and site of absorption due to differences in their chemical characteristics and enzymatic conversion. This review addresses diffusion- and transport-mediated absorption systems for amino acids and carboxylic compounds, best elucidated by in vitro, ex vivo, and in vivo experimental models. Opportunities and limitations in the use of radioisotopes to depict absorption sites as well as host and microbial metabolism are described. Physiological and environmental conditions that lead to changes in gut absorptive capacity and the impact of Met source absorption are also evaluated. This review concludes that any comparison between HMTBa and DL-Met should consider their different behaviors during the absorption phase. Hence, the chemical characteristics of these 2 molecules entail different absorption sites and mechanisms, from passive absorption in the case of HMTBa and HMTBa-Ca to active transporters for DL-Met, HMTBa, and HMTBa-Ca. In addition, the different conversion modes of these 2 molecules further differentiate their absorption modes. Considering these important differences, it is easier to understand the apparent divergence between the conclusions of existing publications. When comparing these 2 molecules, it is recommended to properly adapt to the conditions under which the absorption of Met sources is evaluated.

Metapontum Forest Reserve is an artificial formation located between mouths of Bradano and Basento river, it is composed prevalently of Aleppo pine (Pinus halepensis). In recent years, the Metapontum coast is characterized by a strong erosive process which has really removed the dune behind the beach moving in the inland and causing the decline of the historical pinewood. This negative effect on plant was induced by an increase in soil salinity, which is one of the major abiotic stresses. A clear understanding of the molecular mechanisms involved in plants response to salt stress is fundamentally important for plant biology. The salinity soil causes broad variety of physiological and biochemical processes, as oxidative damage, also has a negative effect on energy metabolism, which unavoidably resulted in a decreased ATP production through photophosphorylation and, thus, affected the Calvin cycle in photosynthesis. A proteomic approach was utilized to identify key protein which result to be directly responsive to salt stress. Total proteins were extracted from the leaves by a combination of TCA—acetone and phenol, and separated by two-dimensional gel electrophoresis at pH 5 - 8. Spots were stained with Coomassie Brilliant Blue and analyzed with the software PDQuest 8.0 (Bio-Rad) to identify differentially expressed polypeptides. Preliminary analysis revealed around 29 differentially expressed proteins, and they were sequenced by MALDI TOF and LC-MS/MS. Sequenced spots were classified in different functional classes.

To obtain a real-time image of atmospheric particulate matter (PM) in highly polluted areas and to understand how the anthropogenic component linked to urban activities (industrial activities, domestic heating, road traffic, waste disposal) can locally affect near-surface measurement of PM, several measurement campaigns were achieved in the Campania region (Southern Italy) using both Lidar and in-situ instruments. A comparison between the obtained results highlights a good correlation between the data and the potential of remote sensing instruments for air quality monitoring. Data analysis was performed in terms of particle backscattering coefficient profile at 355 nm, PM mass concentration, and size distribution. Wind profiles, which covered a range of altitudes from 40 m to 290 m, were also used to study sources and physical processes involved. Measurement carried out in a rural area with a landfill site highlighted the presence of a homogeneous particulate layer throughout the sounded area due to winds driving aerosol from the landfill to the surrounding areas. The size distribution in mass concentration, highlighted a modal diameter moving towards 0.9 and 2 μm with a larger mass concentration of particles in the morning, before noon and in the afternoon when a large number of trucks delivered solid wastes. Moreover, large concentrations of particulate matter were measured in a small urban town with few industrial activities which peak (211 ± 33 μg·m-3) was measured in the direction of the most urbanized area, probably due to the lighting of the domestic heating systems. Bimodal size distribution in number concentration was measured, indicative of two types of atmospheric particles sources: gas and liquid combustion (particles with sizes below 80 nm), including vehicular traffic and domestic gas-heating, and biomass combustion (particles with sizes of the order of 200 - 500 nm). Finally, data collected in a highly populated and industri
