In our study, we aimed to examine the relationship between patient and procedure-related parameters and the development of pancreatitis.

The new era hypothesis of coastal degradation: G(s) elements-gallium, gadolinium, and germanium.

Mining of precious metals contributes to environmental pollution, especially in coastal areas, and conventional treatment methods are not always effective in removing metal contaminants. Some of these metals, such as gadolinium, germanium and gallium, have caused increasing concern worldwide, as little is known about their current concentrations in the aquatic environment and their biological significance. Therefore, the aim of this study was to determine for the first time the variation of average G(s) concentrations (gallium, gadolinium and germanium) by month/season/site differences along the coast of Istanbul.
