Mitochondrial respiratory capacities are not linked to individual variation in hypoxia tolerance and standard metabolic rate in European seabass Dicentrarchus labrax

Journal of Fish Biology, EarlyView.
Abstract In hypoxic environments, fish attempt to regulate their metabolic rate as oxygen levels in the water decline. Individuals that have low energy requirements for maintenance – standard metabolic rate (SMR) – are expected to have higher hypoxia tolerance, measured as the critical water oxygen saturation threshold (Scrit) below which they cannot ...

Comparison between biochemical responses of the teleost pacu and its hybrid Tambacu (Piaractus mesopotamicus xColossoma macropomum) to short term nitrite exposure

Brazilian Journal of Biology
Aquatic environmental factors are very changeable in short periods. Among these factors are pH, temperature, dissolved oxygen, ammonia and ions. Nitrite, as one ion naturally present in aquatic systems, deserves particular consideration as it is highly ...

Diagnosis and Off‐Label Treatment of Subcutaneous Putative Dracunculoid Nematodes in Apteronotus albifrons Originating From Wild‐Caught Fisheries

Journal of Fish Diseases, EarlyView.
ABSTRACT Apteronotus albifrons (Gymnotiformes: Apteronotidae), commonly known as the black ghost knifefish, is a high‐value ornamental fish that is susceptible to various parasites. The affected fish were wild‐caught fisheries and subsequently introduced into a commercial breeding system.

Leukocytes respiratory burst and lysozyme level in pacu (Piaractus mesopotamicus Holmberg, 1887)

Brazilian Journal of Biology
Innate immune responses are useful to determine the health status of fish and to evaluate the effect of immunomodulatory substances in fish farming. Leukocytes respiratory burst was measured in pacu (Piaractus mesopotamicus) using chemiluminescence assay

Essential oil of Lippia origanoides as an anesthetic for Piaractus mesopotamicus: implications for induction and recovery times, ventilatory frequency and blood responses after biometric management [PDF]

Brazilian Journal of Biology
This study evaluated the use of the essential oil of Lippia origanoides (EOLO) as an anesthetic for juvenile pacu, Piaractus mesopotamicus. Two experiments were performed. In Experiment I, anesthetic induction and recovery times and ventilatory frequency

Similarities Between the Lipid Profiles of Skin and Liver of European Sea Bass (Dicentrarchus labrax) Fed Diets With Different Lipid Content

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The fatty acid composition of fish is influenced by species, age, diet, and tissues, which respond differently to dietary lipids. This study examined how two commercial diets with contrasting polyunsaturated fatty acid (PUFA) profiles, affecting eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), alter the fatty acid composition in ...

Postoperative Effects of Celecoxib on Opioid Use and Pain Control After Benign Oropharyngeal Surgery

The Laryngoscope, Volume 136, Issue 9, Page 4072-4080, September 2026.
This study evaluated how the addition of celecoxib to a multimodal pain regimen following tonsillectomy + adenoidectomy, or uvulopalatopharyngoplasty (UPPP) + tonsillectomy affects postoperative opioid use and pain control. Patients who received celecoxib consumed significantly fewer opioids compared to the historic control group, with similar ...
