Background: Eco-anxiety caused by climate change, which is a significant public health problem, has negative effects on sexual and reproductive health, and these effects are expected to increase continuously. This study was conducted to determine the relationship between eco-anxiety caused by climate change and the fertility preferences of women.

Methods: This descriptive study was conducted between June and August 2024 with 491 women at the ages of 18 to 49 who were registered at a family health center.

Children hospitalized for cancer treatment are known to experience high levels of anxiety. This study aimed to examine the effects of making jewelry from beads on the state and trait anxiety levels of children with cancer. This parallel group, randomized controlled trial was conducted on 62 children aged 7-18 who were being treated for cancer.

In this study, novel -benzimidazole-derived calix[4]arene compounds with different structures, and a benzothiazole-derived calix[4]arene compound, were synthesized by a microwave-assisted method and their structures were determined by FTIR, H NMR, C NMR, MALDI-TOF mass spectroscopy, and elemental analysis. The effects of functional calixarenes against bacterial (pBR322 plasmid DNA) and eukaryotic DNA (calf thymus DNA = CT-DNA) were investigated. The studies with plasmid DNA have shown that compounds 6 and 10 containing methyl and benzyl groups, respectively, have DNA cleavage activity at the highest concentrations (10 000 μM).

This paper presents a study on the removal of azo dyes (Reactive Black 5, Trapaeolin 000, Methyl Orange and Direct Violet 51) with calix[n]arene derivatives from aqueous solution into the organic phase in order to explore the potential use of calixarenes as low-cost efficient extractants for wastewater dye removal. The carboxylic acid derivative of calix[8]arene shows highest affinity towards the azo dyes. The influence of NaCl (present in the solution) on extraction process was also studied.

Three beta-cyclodextrin (polymers 1-3) and a starch-based (polymer 4) polymers were synthesized using hexamethylene diisocyanate (HMDI) as a cross-linking agent in dry dimethylformamide and used as a sorbent for the removal of some selected azo dyes from aqueous solutions. The cross-linked polymers were characterized by Fourier transform infrared spectroscopy, thermogravimetric and differential scanning calorimetric analysis. Results of sorption showed that cyclodextrin and starch based polymers can be effectively used as a sorbent for the removal of anionic azo dyes.
