The current study focuses on synthesis and characterization of carbonyl functionalized unsymmetrical diorganotellurium(iv) dichlorides (1-5), dibromide (6), and their characterization by elemental analysis, H, C{H}, and Te NMR spectroscopy. In addition to this, compounds 1, 4 and 5 were further confirmed single-crystal X-ray studies. Reduction of all the dichlorides with NaSO affords labile tellurides, which decompose quickly even at room temperature into the more stable symmetric ditellurides, ArTe.

- Diorganotin complexes with various compositions were synthesized by reacting organotin oxides with a specific ligand in toluene, and a mono-n-butyltin complex was prepared using acetonitrile.
- These complexes were characterized through techniques like FT-IR, NMR spectroscopy, and X-ray diffraction, revealing their coordinated structures and forms.
- The antitumor activities of the first five complexes were tested on T-47D breast cancer cells, with compound 3 showing the highest effectiveness and potential for selective toxicity, positioning it as a promising candidate for breast cancer treatment.
The evolution of pesticide resistance is a widespread problem with potentially severe consequences for global food security. We introduce the resevol R package, which simulates individual-based models of pests with evolving genomes that produce complex, polygenic, and covarying traits affecting pest life history and pesticide resistance. Simulations are modelled on a spatially-explicit and highly customisable landscape in which crop and pesticide application and rotation can vary, making the package a highly flexible tool for both general and tactical models of pest management and resistance evolution.

It shapes plant populations, enhances forest succession, and has multiple, indirect benefits for humans, yet it is one of the most threatened processes in plant regeneration, worldwide. Seed dispersal distances are determined by the diets, seed retention times and movements of frugivorous animals.

Background: Lithium, a mood stabilizer, is known to exhibit neuroprotective effects in animal models and may have anti-dementia effects.
Aims: We used data from Scottish Mental Survey 1932, a population-based cohort study, to investigate the association between lithium in drinking water and dementia rate in humans.
Method: Lithium levels in drinking water from 285 sampling sites across Scotland dating from 2014 were obtained from the sole public water provider (Scottish Water).
