This paper deals with the analysis of long-term changes in population densities at the regional and macro-regional scale and in the density of metapopulations. The following issues concerning estimations are addressed: chronological resolution of demographic changes, estimation of the weight of values for population density in order to transform the initial values included in the sample into the values that may be compared with each other at the regional scale, calibration of the transformed values into real population densities, and the estimation of the weight of values for population density at the scales of macro-regions and for the density of metapopulations. The proposed methods are tested on demographic changes in Central Europe, Southern Scandinavia, Southeastern Europe, and the Near East. The obtained results represent major trends in demographic development, while the proposed methodology could also be applied in other wide-scale demographic analyses.

Effects of urban sprawl due to migration on spatiotemporal land use-land cover change: a case study of Bartın in Türkiye.

Rapid urban growth is a subject of worldwide interest due to environmental problems. Population growth, especially migration from rural to urban areas, leads to land use and land cover (LULCC) changes in urban centres. Therefore, LULCC and urban growth analyses are among the studies that will help decision-makers achieve better sustainable management and planning.

In fluvial environments, the shifting of river channels and bank erosion are frequently caused by both natural and anthropogenic factors. Riverine hazards like bank erosion and course alterations offer severe issues to the riparian villages along the lower basin of the Tista River in India, which substantially influence the livelihoods of inhabitants living there. This research addressed river channel shifting tendency and identified major bank erosion-prone villages along the lower course of the Tista River and challenges to the livelihoods of the riparian people.

Symbioses are major drivers of organismal diversification and phenotypic innovation. However, how long-term symbioses shape whole genome evolution in metazoans is still underexplored. Here, we use a giant clam (Tridacna maxima) genome to demonstrate how symbiosis has left complex signatures in an animal's genome.

Background: Given the negative impact of breast cancer and its treatment on women's self-efficacy in various areas, including sexual function, investigating and understanding ways to enhance sexual function is crucial. The current study aimed to examine the impact of sexual counseling and education based on self-efficacy theory on the sexual function of women with breast cancer.
Method: The trial was a randomized controlled trial with a parallel design, including a pre-test, post-test, and one-month follow-up.

Introduction: Dupilumab is an IL-4 / IL-13 inhibitor monoclonal antibody approved for the treatment of moderate-to-severe atopic dermatitis (AD) with remarkable safety and efficacy profiles. However, former studies have reported an increase in serum eosinophils during treatment, with undetermined clinical significance.
The Objective: of this study is to evaluate changes in blood eosinophils and other laboratory parameters while on dupilumab.
