Cetaceans are highly adapted marine mammals whose survival depends on precise auditory and echolocation systems. Therefore, disease processes affecting these systems, including parasitic infections pose significant morbidity and may result in stranding and death. Here, we describe the pathologic and parasitological findings in an adult, male melon-headed whale ( Peponocephala electra ) stranded dead on the Brazilian coast. The...

Cetaceans are sentinels of marine ecosystem health and are increasingly exposed to protozoal pathogens. This study investigated the occurrence and molecular identity of Sarcocystidae protozoa in 159 stranded cetaceans representing 21 species along the Brazilian coast. Molecular analysis based on PCR amplification and sequencing of the sarcocystid internal transcribed spacer 1 (ITS1) region revealed infections in 14 individuals...

L -asparaginase is an amidohydrolase enzyme that catalyses the hydrolysis of L-asparagine into L-aspartic acid and ammonia. This enzyme has significant biotechnological applications, functioning as an antineoplastic agent in the pharmaceutical industry and as a tool for reducing acrylamide formation in the food industry. This study aimed to identify a filamentous fungus strain capable of synthesizing a new L -asparaginase and...

Canistrum (Bromeliaceae) comprises 13 species endemic to the Atlantic Forest and is subdivided into two subgenera ( Canistrum and Cucullatanthus ). This study aimed to characterize the morphology of reproductive structures (pollen and stigma), assess pollen viability and stigma receptivity across all species of the genus, and evaluate the taxonomic, reproductive, and conservation relevance of these characters. Analyses were co...

Since the 20th century, global biodiversity indicators declined, especially for freshwater ecosystems. In European Union, to counter this, the enactment of the Habitats Directive (HD) and the Water Framework Directive (WFD) established legally binding environmental objectives for Member States. Thus, identifying where HD and WFD non‐compliance occurs is critical, as these locations represent areas of restoration needs for fres...

Nanostructured lipid carriers (NLCs) decorated with sulfhydryl-modified surfactants have recently gained attention for delivering BCS Class IV drugs. However, the impact of the chain-length of these surfactants on the permeation and bioavailability properties of NLCs is still unknown. Therefore, this study investigates the effect of surfactant chain-length on the mucoadhesive, permeation, and bioavailability properties of NLCs...
