Genomics profile of ocular toxicity in zebrafish exposed to environmental contaminants.

Environmental contaminants present a significant and growing threat to aquatic ecosystems, with a particularly notable impact on the visual systems of aquatic organisms, including zebrafish. Zebrafish (Danio rerio) are increasingly used in toxicological research because of their genetic and physiological similarities to humans, making them an ideal model for studying the effects of environmental toxins. Among the most frequently observed and studied ocular malformations in zebrafish exposed to toxicants are microphthalmia, cyclopia, and coloboma, all of which involve developmental abnormalities of the eyes.

Emergence of recurrent urinary tract infection: Dissecting the mechanism of antimicrobial resistance, host-pathogen interaction, and hormonal imbalance.

Most of these substances flow through the digestive tract and food chains, becoming emerging organic contaminants in various abiotic and biotic environmental media. Here, we predict the mutagenicity and carcinogenicity of commonly used sugar substitutes using in silico based methods.

Delineating the emergence of thermally tolerant Symbiodiniaceae genotypes across the dominant coral species of a turbid reef: Adaptation and resilience strategy.

Climate change-induced rise in sea surface temperatures has led to an increase in the frequency and severity of coral bleaching events, ultimately leading to the deterioration of coral reefs, globally. However, the reef-building corals have an inherent capacity to acclimatize to thermal stress on pre-exposure to high temperatures by altering their endosymbiotic Symbiodiniaceae community composition towards a thermal tolerant composition. This reorganisation may become an important tool in coral's resilience to rapid environmental change.
