This study evaluated the anesthetic combination of dexmedetomidine and ketamine in free-ranging Phrynops geoffroanus , assessing cardiopulmonary and sedative variables, as well as pharmacological reversal with atipamezole. Twenty-five adult individuals were allocated into two groups: HG (dexmedetomidine 0.1 mg/kg + ketamine 10 mg/kg; n = 13) and LG (dexmedetomidine 0.05 mg/kg + ketamine 10 mg/kg; n = 12). Heart rate, respirato...

The level of difficulty of a secondary cognitive task (DT) can affect gait and cortical activity distinctly in individuals with Parkinson’s disease (PD). During a simpler ST, individuals with PD may use a compensatory neural mechanism by reallocating neural resources to preserve gait performance; for difficult DT, this compensation may not be the case. However, whether different levels of difficulty of a single-domain DT would...

Candida parapsilosis sensu stricto has emerged as a major cause of healthcare-associated candidemia, with increasing reports of fluconazole resistance worldwide. This resistance is most commonly associated with amino acid substitutions in Erg11p, particularly Y132F; however, regional variation in resistance mechanisms and clonal dissemination remains not fully understood. This study investigated the molecular epidemiology and...

Purpose Strongyloidiasis is an intestinal helminthiasis that can induce structural alterations in the intestinal mucosa during infection. The present study evaluated histomorphometric alterations of the small intestine in mice experimentally infected with Strongyloides venezuelensis and treated with Rosmarinus officinalis essential oil. Methods Infected animals were treated orally with R. officinalis essential oil (200 or 400...

Rice is essential for global food security. However, the effects of phosphorus (P) and silicon (Si) interaction on macronutrient accumulation in rice grown in tropical soils remain poorly understood, particularly regarding the persistence of these effects in subsequent crops. This study aimed to investigate the combined influence of Si and P levels on the accumulation of macronutrients (N, P, K, Ca, Mg, and S) and Si in the sh...

The relative importance of environmental selection, dispersal, and demographic stochasticity in structuring aquatic communities remains poorly resolved, especially in human-impacted Neotropical regions. Using diatoms, we assessed how local environmental conditions, catchment land use, and spatial factors shape community richness and composition in subtropical streams, and whether responses differ among common, rare, and very r...

The aim of the present study was to evaluate the effects of dietary supplementation with the microalgae Nannochloropsis oculata and Phaeodactylum tricornutum , either separately or in combination, on growth performance, lipid profile, haematoimmunological parameters, and resistance to Edwardsiella tarda infection in Nile tilapia ( Oreochromis niloticus ). A total of 960 juvenile Nile tilapia (2.87 ± 0.68 g and 5.65 ± 0.16 cm)...
