“…Mesophilic fungi (Alternaria alternata, Cladosporium herbarum) act only as aeroallergens (Aguilera et al, 2022;Hughes et al, 2022), and sensitization and exposure to species of these genera are associated with the development of asthma and rhinitis (Bhankhur et al, 2019).…”

Fungi are ubiquitous living beings present in the indoor and outdoor environment. Spores and mycelium of fungi carried by air have a great impact on ecology, the economy, in particular on agriculture, as well as on human health. It has been established that the incidence of fungal pathologies has increased rapidly over the past two decades. Fungi can cause allergies, and can be infectious agents, especially in immunocompomised people. Fungal spores are powerful sources of allergenic molecules covering a wide range of biochemical classes. Together with the fungal mycelium, they can cause the development of hypersensitivity, which is one of the most common pathological immune responses. Currently, known fungal aeroallergens are found in 3 fungal classes – Basidiomycota, Ascomycota, and Zygomycota. Therefore, the goal of our work was to determine the level of sensitivity to fungal allergens in the population of Vinnytsya region in order to prevent allergies caused by fungi. Data analysis of IgE-mediated, genuine, sensitization to fungal allergens of Alternaria (Alt a 1, Alt a 6), Cladosporium (Cla h, Cla h 8), Aspergillus (Asp f 1, Asp f 3, Asp f 4, Asp f 6), Penicillium (Pen ch), Malassezia (Mala s 11, Mala s 5, Mala s 6) and Saccharomyces (Sac c) was carried out using a component-resolved allergy diagnostics by ALEX2 test. The data of 87 residents of the Vinnytsya region aged 1 to 66 who underwent molecular allergy diagnostics in 2020–2022 were taken into account. Sensitivity to fungal allergens was observed in 20 patients or 23.0% of those tested. Among them, the highest level of sensitivity, in 15 patients or 75% of the number of sensitive individuals, was observed for the Alternaria fungus. The allergen component Alt a 1 caused high and very high levels of sensitization in 3 and 7 patients, respectively. Sensitivity to Aspergillus and Malassezia had the second highest rate: 6 patients or 30% of sensitized individuals were sensitive to these two fungal allergens. Alternaria was the most important fungal agent causing sensitization of the examined population of Vinnytsya region. Aspergillus allergens, known for their ability to cause both allergic and infectious reactions, were next in clinical importance. Cladosporium, which usually produce a highest number of spores in the atmosphere among all fungi, was characterized by low allergenicity. High levels of both specific and total immunoglobulin E can be prognostic markers of clinical manifestations of fungal allergy. This information should be taken into account for the prevention of fungal allergy among the population when creating allergy forecasts.

Monitoring and controlling of the showcase environment in a special exhibition in Shanghai Museum are described in this work. The long show time started on March 2022 and ended on January 2023. Various items were shown in this exhibition with different combination modes. Air conditioners, humidifiers and three kinds of passive humidity controlling methods were applied to this exhibition. Massive raw monitoring data are given and some series of data are transformed into specific values to conduct various analyses. Factors including outdoor climate, exhibition hall structure, attendance, showcase structure, tightness and volume, monitor position and object combination modes are discussed in order to assess their effect on monitoring and controlling of temperature and relative humidity. The relation between the average value of temperature (or relative humidity) fluctuation in the whole exhibition period and the corresponding range of maximum temperature (or relative humidity) fluctuation in any 24 h is analyzed in order to obtain the probability of abnormally high fluctuation. The results show that the temperature control target is reached in general, while some unreasonable showcase structures and settings are responsible for the difficulty in monitoring and controlling of relative humidity. By conducting the analysis of big continuous historical data and learning the average values and the ranges reached, it is possible to assess the current environmental risk and predict the future risk in a simple way.
