Summary: This study aimed to identify potential new drug targets/candidates for multi-drug-resistant Mycobacterium tuberculosis (Mtb) through computational techniques. The protein structure of ribonuclease VapC2 of Mtb H37Rv was analyzed, and docking studies were performed with 22 anti-TB drugs. Rifampicin showed the best binding energy and was selected as the parent molecule for designing derivatives. One of the derivatives, RIF-155841, showed activity in inhibiting VapC2. Molecular dynamics simulations confirmed the stability of the VapC2-RIF155841 complex, and a chemical synthesis scheme was designed for future validation.

Summary: Statistical models are crucial for data analysis, and researchers are always looking for potential or the latest statistical models to fit different data sets. In this investigation, a T-X transformation and the Gumbel Type-II model were used to create an improved statistical model. Simulation evaluation was conducted to assess the efficacy of the parameters. Two actual data sets were utilized to demonstrate the application of the T-X approach in producing the new and improved Gumbel Type-II (NIGT-II) distribution, and the results suggest that the NIGT-II distribution outperforms the Gumbel Type-II distribution.

Summary: This study compared concurrent measurements of three-dimensional wind velocities made by three co-located wind profilers operating at different frequencies. The results showed small differences in measurements among the wind profilers, but larger discrepancies when compared to rawinsonde measurements. This suggests that wind profiler-measured horizontal wind velocities are more reliable and accurate than rawinsonde measurements.

Summary: Model states are often compared with scattered in-situ observations to validate their accuracy, but there is no unified diagram to showcase statistical measures of correlation, root mean square error, and standard deviation across all locations. In this study, we propose the Performance Across Space (PAS) diagram and the Performance Across Time (PAT) diagram to address this issue. Through realistic ocean models and in-situ observations, we demonstrate the effectiveness of these diagrams in evaluating model performance and data assimilation.

Summary: This study analyzed the macrofaunal and meiofaunal assemblages in a coastal lagoon and found that they showed distinct responses to environmental gradients. The relationship between the number of individuals and species richness in both assemblages followed theoretical predictions. The study also suggests that these relationships can be used as screening-level indicators to assess sediment quality and associated bioeffects in eutrophic lagoons.

Summary: This article discusses a potential multi-hazard scenario resulting from an earthquake in the highly seismogenic area of the Mediterranean Sea, Augusta Bay. The bay is heavily contaminated with mercury due to long-term industrial exploitation. Utilizing a high-resolution hydrodynamic and transport model, the article calculates the enhanced spreading of mercury in the open sea following the damage to an artificial damming system. The simulated scenario highlights the need for a reevaluation of risk management in marine areas with significant contamination.

Summary: Understanding water circulation in oceans and coastal seas is crucial for oceanographic and climate research. Hydrodynamic modelling has become a fundamental tool for describing marine dynamics and human impact on the sea. The semi-enclosed Adriatic Sea serves as a natural laboratory for hydrodynamic modelling, with various models applied to this region. However, current modelling studies often underestimate the importance of representing land-coastal-sea fluxes in detail. Recommendations for model implementation are provided to enhance the applicability of hydrodynamic models in future studies.

Summary: The Strait of Messina in the Mediterranean Sea is a unique area that connects different regions and provides valuable insights into ecosystems shifts. This study suggests that hydrodynamic conditions may transport populations of P. noctiluca from pelagic waters to the coast, leading to outbreaks near the Mediterranean Sea's coastline. Visual observations and numerical experiments support the hypothesis of a connectivity between the Aeolian Islands Archipelago and the Strait of Messina, particularly during the first half of the year. This connectivity serves as an important factor for the successful life cycle of Pelagia noctiluca.

Summary: This study assessed the effectiveness of biological trait analysis (BTA) as an ecological indicator in a Mediterranean transitional system. The results showed spatial changes in macrobenthic assemblage diversity along the riverine-lagoon-sea gradient, which were well reflected in the Ecological Quality Status (EQS) values based on M-AMBI. The BTA approach appeared to be a promising method for assessing the environmental quality of brackish-water systems.

Summary: The aim of this study was to investigate the long-term changes in the coastal stretch of the Lido barrier island, and assess the impacts of human interventions on the system. The study examined coastal modifications using aerial photographs from 1955-2019 and found a positive long-term trend in shoreline changes, with moderate erosion in recent periods. Human interventions, including engineering structures and the MoSE system, significantly influenced beach erosion and progradation. The study concludes that this area should be given higher consideration in spatial planning within integrated coastal zone management, especially considering future sea-level rise.

Summary: Several factors have led to the decline in population of the Mediterranean monk seal over time. Despite the disappearance of documented breeding sub-populations, recent sightings have been reported from most of the species' former habitat. Our research in the Salento coast, Italy, used three different methodologies to collect data on monk seal presence. The study revealed historical and recent records of sightings, suggesting the species' rarity and the need for a regional approach to aid its recovery.

Summary: This study investigated the spatiotemporal variation in taxonomic indices and functional traits of nematode fauna in the Cabras Lagoon, Italy. The results showed that the taxonomic structure was the most sensitive metric to document changes in the nematode assemblage, and salinity and organic matter enrichment were found to be the primary drivers of nematode distribution. Temperature mainly affected faunal composition, abundance, and diversity. The study highlights the importance of combining taxonomic and functional approaches to assess the environmental quality of lagoonal ecosystems.

Summary: Since 2000, hydrological data of the Mediterranean Sea, particularly the western and central sub-basins, have been collected to study the hydrodynamics at coastal and open sea scales. A total of 1468 hydrological casts were conducted in 29 oceanographic cruises, and the data were carefully quality controlled and made available in open-access repositories. The findings of the study include staircase systems in the Tyrrhenian Sea and Algero-Provencal sub-basin, as well as the spreading of the Western Mediterranean Transient.
