Article Abstract
In this study, we propose an indicator of air pollution exposure to identify potential hazardous areas for human health in the Amazon and Central-West Regions of Brazil from 2010 to 2019. This indicator aggregates both concentrations and time of exposure to fine particulate matter (PM2.5), according to the current limit recommended by the World Health Organization (WHO). We used daily PM2.5 averages obtained from the Brazilian Health Integrated Environmental Information System (SISAM) to calculate the percentages of days with PM2.5 concentrations exceeding the limit of 15µg/m³ per year and per month. From 2010 to 2019, the months from August to October presented the largest areas and the highest percentages of days with unacceptable pollution concentration values, harmful to human health. These areas were concentrated in the Arc of Deforestation. Therefore, 60% of the residents of the Amazon and Central-West regions were subjected to inadequate air quality for approximately six months per year. The proposed indicator is reproducible and appropriate to monitor areas of exposure and risk for human health.

Background: Fertilization of plants with selenium (Se) can enhance their resistance to abiotic stresses and improve human health and nutrition. However, Se fertilization in olive trees remains underexplored. This study evaluated the effect of foliar sodium selenite fertilization on leaf Se content, oxidative stress, olive tree productivity, biofortification of extra virgin olive oils (EVOO), and their physicochemical and antioxidant attributes in two mature 'Arbequina' olive orchards.

Urbanization and increasing vehicular traffic have intensified air pollution, particularly the accumulation of particulate matter (PM), trace elements (TEs), and polycyclic aromatic hydrocarbons (PAHs) in urban environments. These pollutants pose significant risks to human health, urban ecosystems, and biodiversity. This study evaluates the efficacy of mixed-species vegetation barriers, comprising , , , and , in mitigating air pollution along three road types (highway, urban, and suburban).

The dengue virus (DENV) poses a significant threat to human health, accounting for approximately 400 million infections each year. Its genome features a circular structure that facilitates replication through long-range RNA-RNA interactions, utilizing cyclization sequences located in the untranslated regions (UTRs). To gain new insights into the organization of the DENV genome, we purified the 5' and 3' UTRs of DENV in vitro and examined their structural and binding properties using various biophysical techniques combined with computational methods.

BACKGROUND The SENTINEL influenza surveillance system has been used in Poland since 2004, incorporating both epidemiological and virological monitoring of influenza viruses. SENTINEL works in cooperation with general practitioners, 16 Voivodship Sanitary Epidemiological Stations (VSES), and the National Influenza Centre (NIC). NON-SENTINEL samples are collected from places that do not participate in the SENTINEL program.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.
