It is generally accepted that radon emission is strongly influenced by the geological characteristics of the bedrock. However, transport in-soil and entry paths indoors are defined by other factors such as permeability, building and architectural features, ventilation, occupation patterns, etc. The purpose of this paper is to analyze the contribution of each parameter, from natural to man-made, on the radon accumulation indoors and to assess potential patterns, based on 100 case studies in Romania. The study pointed out that the geological foundation can provide a reasonable explanation for the majority of the values recorded in both soil and indoor air. Results also showed that older houses, built with earth-based materials, are highly permeable to soil radon. Energy-efficient houses, on the other hand, have a tendency to disregard the radon potential of the geological foundation, causing a higher predisposition to radon accumulation indoors and decreasing the general indoor air quality.

Air microbial pollution in touristic areas poses a risk for both the integrity of an ecosystem and human health. Microbiological monitoring together with environmental parameters monitoring allows for the assessment of the impacts and formulation of sound management decisions to protect humans and ecosystems. Four show caves from the Carpathian Mountains were selected for our study. The caves were sampled monthly to obtain an overview of the changes that occur over a yearly cycle. For the microbial monitoring, we used RIDA ® COUNT test plates, while the environmental parameters were monitored with a variety of devices. Second and third generations of microbes extracted from the plates were grown on specific media for the purpose of 16S rRNA and 18S rRNA extraction and taxa identification. The bacterial communities identified in the air samples in the four investigated show caves were dominated by Staphylococcus , while regarding the fungi communities, Penicillium was more likely to occur in the touristic part of the caves and Cladosporium in the non-visited passages. Together with data on number of visitors, number of bats and radon levels we were able understand the impact of tourists on the cave environment and to generate microbiological risk maps for human health. This type of comprehensive study can be used not only to protect the integrity of a touristic area from the impacts caused by the introduction of allochthonous organic matter, but also for the protection of the tourists and guides from potential pathogenic taxa.

Soil radon gas and/or its exhalation rate are used as indicators for some applications, such as uranium exploration, indoor radon concentration, seismic activity, location of subsurface faults, etc., and also in the studies where the main interest is the field verification of radon transport models. This work proposes a versatile method for the soil radon sampling using a special manner of pumping. The soil gas is passed through a column of charcoal by using passive pumping. A plastic bottle filled with water is coupled to an activated charcoal column and the flow of water through an adjustable hole made at the bottom of bottle assures a controlled gas flow from the soil. The results obtained for the activity of activated charcoal are in the range of 20-40 kBq/m^sup 3^, for a depth of approximately 0.8 m. The results obtained by this method were confirmed by simultaneous measurements using LUK 3C device for soil radon measurements. Possible applications for the estimation of radon soil potential are discussed. [PUBLICATION ABSTRACT]

Băiţa-Ştei mine is an open pit mine in NW Romania (West Carpathian Mountains). It was the largest surface uranium deposit in the world. Two means of uranium transport and dissemination were used over time. The first was the natural way, represented by transportation of geological sediments by Crişul-Băiţa River that crosses the Băiţa surface deposit. These sediments were used as building materials (stone, gravel, sand). The second way was related to the people living in this valley, who used also the uranium waste as building material. The preliminary indoor radon concentrations measured in the buildings ranged from 40 to 4000 Bq m −3 with a mean value of 241 Bq m −3 . A focused radon survey facilitated the selection of 20 houses with the highest indoor radon that were therefore proposed for remediation. To find the radon sources of these houses, systematic investigations on radon were performed. The remedial measures for these 20 houses were tested on a chosen pilot house.

Convergent evolution is pervasive in nature, but it is poorly understood how various constraints and natural selection limit the diversity of evolvable phenotypes. Here, we analyze the transcriptome across fruiting body development to understand the independent evolution of complex multicellularity in the two largest clades of fungi—the Agarico- and Pezizomycotina. Despite >650 My of divergence between these clades, we find that very similar sets of genes have convergently been co-opted for complex multicellularity, followed by expansions of their gene families by duplications. Over 82% of shared multicellularity-related gene families were expanding in both clades, indicating a high prevalence of convergence also at the gene family level. This convergence is coupled with a rich inferred repertoire of multicellularity-related genes in the most recent common ancestor of the Agarico- and Pezizomycotina, consistent with the hypothesis that the coding capacity of ancestral fungal genomes might have promoted the repeated evolution of complex multicellularity. We interpret this repertoire as an indication of evolutionary predisposition of fungal ancestors for evolving complex multicellular fruiting bodies. Our work suggests that evolutionary convergence may happen not only when organisms are closely related or are under similar selection pressures, but also when ancestral genomic repertoires render certain evolutionary trajectories more likely than others, even across large phylogenetic distances.

INTRODUCTION:The magnitude and modifiers of the association between acute pancreatitis (AP) and pancreatic cancer (PC) are unclear. This systematic review and meta-analysis aimed to quantify the occurrence of PC in AP, the association of PC after AP, and the impact of specific risk factors on PC diagnosis.METHODS:The systematic search was conducted in PubMed, EMBASE, and Central Register of Controlled Trial from inception until July 14, 2025 (PROSPERO: CRD42023470350). Eligible studies included adult populations reporting on the association between AP and PC. Primary outcomes included prevalence, incidence, and diagnosis of PC in individuals with AP, including subset analyses of specific clinical and demographic factors. Meta-analyses were performed using random-effects models to calculate pooled outcome measures and corresponding 95% confidence intervals (CI).RESULTS:A total of 61 studies were included. The prevalence of PC among AP patients was 2% (CI: 2%-4%). The time-dependent analysis revealed an increased hazard of PC in AP vs no AP: <24 months (HR: 31.94, CI: 9.35-109.09), 24-60 months (HR: 2.68, CI: 1.65-4.37), and >60 months (HR: 1.71, CI: 1.22-2.40). AP patients with subsequently diagnosed chronic pancreatitis (OR: 3.71, CI: 2.00-6.90), new-onset diabetes mellitus (OR: 2.22, CI: 1.02-4.84), idiopathic AP (OR: 2.97, CI: 1.44-6.13), and older than 50 years (OR: 4.04, CI: 2.73-5.97) showed significantly increased odds of having PC. We found no evidence for increased odds for PC with AP severity, smoking, and alcoholic and gallstone etiologies.DISCUSSION:Patients with AP have a higher likelihood of PC diagnosis, especially within the first 2 years. Although the association decreases with time, it remains significant long term. Newly diagnosed chronic pancreatitis, new-onset diabetes mellitus, idiopathic AP may further elevate the likelihood of PC diagnosis. PC diagnosed after AP tends to occur at a younger age, more often at an earlier stage, typically in the pancreatic head.

The economic crisis caused by Covid-19 differs from previous economic crises in several ways. It is a global event that developed unexpectedly and hit the world unprepared, primarily attacking human resources, requiring strong governmental measures. The involvement of the human sphere directly affected people’s income and lives through labour market effects. Based on literature and statistical data, this study analyses the evolution of the unemployment data of 11 countries (Australia, Chile, the UK, Israel, Japan, China, Hungary, Germany, Italy, Turkey, and the US) and two country groups (EU-27 and the Organisation for Economic Co-operation and Development – OECD) during the economic crisis. Based on the results, the authors identified three distinct groups of countries with 1. moderate growth, slow consolidation; 2. robustious upturn, fast then slow correction, and 3. individual patterns. The study demonstrated how government measures took effect differently from the unemployment perspective. The authors referred to the influence of the inhabitants’ collective way of thinking and considered it essential to emphasise the positive impact of vaccines.
