Herbal bioactive compounds are effective in enhancing the antioxidant and immune status of fish, as they effectively neutralize oxidative stress. The present study examined the effectiveness of Ivy () leaf extract (ILE) on growth performance, immune responses, antioxidant parameters, and the expression of immune-related genes in rainbow trout (). Four test diets were prepared as follows: a control diet at 0 mg of ILE (ILE0) and diets of 100 mg (ILE100), 150 mg (ILE150), and 200 mg (ILE200) of ILE/kg.

The ocean conditions along the main migratory route of juvenile salmon in British Columbia are characterized by high variability in CO, with the amplitude, duration, and frequency of ocean acidification events exacerbated by climate change. Similarly, the variability in ocean conditions affects the abundance and diversity of plankton prey, leading to areas of food paucity for juvenile salmon.

However, certain species within the Persian Gulf exhibit remarkable resilience to elevated temperatures compared to their counterparts in other reef systems. To understand the thermal tolerance in Persian Gulf corals and their molecular responses to extreme warm temperatures, Acropora downingi specimens collected from Larak Island were subjected to a heat shock of 34 ± 1 °C.

Although molecular technologies have advanced our understanding of how organisms respond to stressors in laboratory settings, the ability to detect physiological responses to specific stressors under complex field conditions remains underdeveloped. This research applied multi-stressor challenge trials on coho salmon, employing the "Salmon Fit-Chips" genomic tool and a random forest-based classification model to develop classifiers predictive for chronic thermal and hypoxic stress, as well as salinity acclimation, smolt stage and morbidity status.

Several studies have reported the use of bamlanivimab as a promising treatment option for COVID-19.
Aim: To synthesize the latest evidence for the efficacy and safety of bamlanivimab alone in the treatment of adult patients with COVID-19.
This study aimed to compare the efficacy and safety of nirmatrelvir/ritonavir (Paxlovid) with molnupiravir in the treatment of coronavirus disease 2019 (COVID-19). To end this, PubMed, Cochrane Library, Web of Science, medRxiv, and Google Scholar were systematically searched to collect relevant evidence up to February 15, 2023. The risk of bias was evaluated using the risk of bias in nonrandomized studies of interventions tool.

To this end, we successfully knocked-in the targeted NR gene of using the bacterial phytase gene cassette through direct delivery of the CRISPR/Cas9 system as the ribonucleoprotein (RNP) complex consisting of Cas9 protein and the specific single guide RNAs (sgRNAs). The insertion site editing was confirmed by PCR and sequencing of the transgene positive clones.

Water quality degradation due to lake eutrophication and climate change contributes to the risk of extirpation for the endangered Cultus Lake sockeye salmon. Sockeye salmon juveniles experience both low-oxygen water in profundal lake habitats and elevated temperatures above the thermocline during diel vertical migrations in summer and fall when the lake is thermally stratified. We used a transcriptomic tool (Salmon Fit-Chip) to determine whether salmon were experiencing thermal and/or hypoxic stress during this period.

The ubiquitous distribution of microplastics (MPs) across marine habitats has led to an increased investigation of their potential impacts on the marine food chain and consequent human exposure. The two fish species Chelon aurata and Rutilus kutum that account for over 50% of the total catch in the Caspian Sea were assessed relative to the presence of MPs in their digestive system. Samples were collected from 6 stations in the southern Caspian Sea from February to March 2017.

Our goal was to discover and validate gill gene expression biomarkers specific to the hypoxia response in salmonids across multi-stressor conditions. Gill tissue was collected from 24 freshwater juvenile Chinook salmon (), held in normoxia [dissolved oxygen (DO) > 8 mg L] and hypoxia (DO = 4‒5 mg L) in 10 and 18° temperatures for up to six days.

Yet, life stage and overall condition can dictate tolerance thresholds to heightened environmental stressors, such that stress may not be equally felt across individuals and at all times. Also, the transcriptional responses induced by environmental changes can reflect both generalized responses as well as others that are highly specific to the type of change being experienced.
