Pufferfish, known for their unique dental structures and body features, can face complications such as overgrown teeth, leading to difficulties in feeding and potential health issues. This study aims to report the diagnosis, treatment plan, and outcomes of a dental intervention addressing a case of overgrown teeth in a black-spotted pufferfish () housed in an aquarium in the southeastern region of Brazil. The article discusses the challenges encountered during the treatment process and provides insights into the importance of proactive dental care in aquatic species.

Adenosine deaminase participates in purine metabolism by converting adenosine into inosine. The most frequent functional polymorphism of adenosine deaminase (22G→A) (ADA1*2) exhibits 20-30% lower enzymatic activity in individuals with the G/A genotype than individuals with the G/G genotype.

- The study investigated the impact of pesticide exposure on farm workers in Rio Grande do Sul, Brazil, by measuring specific enzyme activities and DNA damage.
- Results showed significant reductions in butyrylcholinesterase (BChE) and delta-aminolevulinic acid dehydratase (ALA-D) activities among exposed workers compared to a control group.
- The analysis indicated elevated DNA damage in the exposed group but found no notable differences in hematological, lipid, or micronucleus test results based on age or smoking status; the use of personal protective equipment (PPE) appeared crucial for reducing contamination risk.
