Remodeling of the epigenetic landscape in rainbow trout, Oncorhynchus mykiss, offspring in response to maternal choline intake.

This project focused on evaluating the effects of maternal dietary choline intake on global DNA methylation profiles and related transcriptional changes in rainbow trout offspring. Three experimental diets were formulated to test different levels of choline intake: (a) 2065 ppm choline (Low Choline, 0 % supplementation), (b) 5657 ppm choline (Medium Choline, 0.6 % supplementation), and (c) 9248 ppm choline (High Choline, 1.

Whole-Genome Resequencing Reveals Polygenic Signatures of Directional and Balancing Selection on Alternative Migratory Life Histories.

Migration in animals and associated adaptations to contrasting environments are underpinned by complex genetic architecture. Here, we explore the genomic basis of facultative anadromy in brown trout (Salmo trutta), wherein some individuals migrate to sea while others remain resident in natal rivers, to better understand how alternative migratory tactics (AMTs) are maintained evolutionarily. To identify genomic variants associated with AMTs, we sequenced whole genomes for 194 individual trout from five anadromous-resident population pairs, situated above and below waterfalls, in five different Irish rivers.

Adapting generalized suitability curves from Brown trout to Minnow using 1D and 2D aquatic habitat models.

The article focuses on adapting generalized depth preference and flow velocity characteristics from Brown trout (Salmo trutta morpha fario) to the Minnow (Phoxinus phoxinus). The results obtained were used to model habitat suitability with 1D and 2D models. Since 1995, research on assessing aquatic habitat quality has been ongoing on 77 mountain streams in Slovakia.

Intracellular metabolome elucidates the time-of-day-dependent response to hydrogen peroxide in salmonid gill epithelial cells.

The internal timekeeping system regulates the daily cycle of physiological and behavioural changes in living organisms. This rhythmic phenomenon also influences cellular responses to reactive oxygen species, such as hydrogen peroxide (HO). However, the temporal interaction between HO and fish mucosal cells is not well understood.

Temperature-Induced Seasonal Dynamics of Brain Gangliosides in Rainbow Trout ( Walbaum) and Common Carp ( L.).

This study aimed to determine the expression and distribution of gangliosides in specific regions of the brains of rainbow trout ( Walbaum) and common carp ( L.) with regard to seasonal temperature changes. Seasonal changes in ganglioside expression and distribution within the species were expected.

Effect of Dietary (APS) on the Growth Performance, Antioxidant Responses, Immunological Parameters, and Intestinal Microbiota of Coral Trout ().

The potential effects of (APS) were evaluated in coral trout (). Five APS levels (0%, 0.05%, 0.

Dietary Thymol Supplementation Promotes Antioxidant Responses and Thermal Stress Resistance in Rainbow Trout, .

Rainbow trout fingerlings were fed, in triplicate, diets supplemented with 0 (CTL), 50 (50 TM), 100 (100 TM), 200 (200 TM), 400 (400 TM) and 800 (800 TM) mg/kg of thymol, followed by 48 h of thermal stress. Growth performance and humoral immunological parameters showed no significant responses to dietary thymol concentrations. Fish fed 50-400 mg/kg thymol diets had significantly higher survival after heat stress.

Unpredictable Repeated Stress in Rainbow Trout () Shifted the Immune Response against a Fish Parasite.

Farmed fish are regularly subjected to various stressors due to farming practices, and their effect in the context of a disease outbreak is uncertain. This research evaluated the effects of unpredictable repeated stress in rainbow trout challenged with the ciliate , known to cause white spot disease in freshwater fish. Before and after the pathogen exposure, fish were handled with a random rotation of three procedures.

A systematic review of the toxic potential of parabens in fish.

Parabens are the most prevalent ingredients in cosmetics and personal care products (PCPs). They are colorless and tasteless and exhibit good stability when combined with other components. Because of these unique physicochemical properties, they are extensively used as antimicrobial and antifungal agents.

Effects of hemodynamic load on cardiac remodeling in fish and mammals: the value of comparative models.

The ability of the vertebrate heart to remodel enables the cardiac phenotype to be responsive to changes in physiological conditions and aerobic demand. Examples include exercise-induced cardiac hypertrophy, and the significant remodeling of the trout heart during thermal acclimation. Such changes are thought to occur in response to a change in hemodynamic load (i.

Communicating Risk in Imaging: A Scoping Review of Risk Presentation in Patient Decision Aids.

Purpose: Best practices exist for communicating medical information to patients, but there is less emphasis on methods to communicate risks, especially in medical imaging. The authors conducted a scoping review of patient decision aids in medical imaging and characterized the presentation methods of imaging risks.

Methods: Embase, MEDLINE, CINAHL, and PsychINFO were searched to identify studies involving patient decision aids used in diagnostic imaging that communicated the risks.

Listeria monocytogenes in the seafood industry: Exploring contamination sources, outbreaks, antibiotic susceptibility and genetic diversity.

Fish and seafood are rich sources of protein, vitamins, and minerals, significantly contributing to individual health. A global increase in consumption has been observed. Listeria monocytogenes is a known problem in food processing environments and is found in various seafood forms, including raw, smoked, salted, and ready-to-eat.

Large language models can help with biostatistics and coding needed in radiology research.

Introduction: Original research in radiology often involves handling large datasets, data manipulation, statistical tests, and coding. Recent studies show that large language models (LLMs) can solve bioinformatics tasks, suggesting their potential in radiology research. This study evaluates an LLM's ability to provide statistical and deep learning solutions and code for radiology research.

Profiling growth performance, insulin-like growth factors, and IGF-binding proteins in rainbow trout lacking IGFBP-2b.

Insulin-like growth factor-binding proteins (IGFBPs) regulate insulin-like growth factor (IGF) signaling, but IGFBP-specific functions are not well characterized in fishes. A line of rainbow trout () lacking a functional IGFBP-2b was produced using gene editing and subsequent breeding to an F2 generation. This loss-of-function model [IGFBP-2b knockout (2bKO)] was subjected to either continuous feeding or feed deprivation (3 wk) followed by refeeding (1 wk).

Environmental Implications of Ionic Liquid and Deep Eutectic Solvent in Geothermal Application: Comparing Traditional and New Approach Methods.

The significant surge of ionic liquids (ILs) research over the past decade has led to the formation of various novel ionic liquid compounds and their diverse applications. Enhanced geothermal systems (EGS) for geothermal power generation are an emerging IL application as a heat extraction fluid. The once widely held belief in the environmentally friendly characteristics of ionic liquids, mainly due to their insignificant vapor pressure, is now being scrutinized.

A Comparative Study of Phase I and II Hepatic Microsomal Biotransformation of Phenol in Three Species of Salmonidae: Hydroquinone, Catechol, and Phenylglucuronide Formation.

The biotransformation of phenol at 11 °C was studied using pre-spawn adult rainbow () (RBT), brook () (BKT), and lake trout () (LKT) hepatic microsomal preparations.
