Effects of 4-n-nonylphenol in liver of male and female viviparous fish (Poecilia vivipara)
Chemosphere. 2022 Sep 21:136565. doi: 10.1016/j.chemosphere.2022.136565. Online ahead of print.ABSTRACT4-n-Nonylphenol (NP) is one of the most toxic alkylphenols found in the environment. To evaluate the transcriptional effects of NP in the viviparous fish Poecilia vivipara, a hepatic transcriptome and qPCR analysis of genes were carried out. Guppies separated by sex were injected with two doses of NP (15 μg/g and 150 μg/g) or peanut oil (control). After 24 h, analysis of transcriptional level of Aryl Hydrocarbon Receptor (AhR), Estrogen Nuclear Receptor Alpha (ER), Pregnane X Receptor (PXR), Cytochromes P450 (CYP1A, CYP...

Evaluation of the Use of Diluted Formic Acid in Sample Preparation for Elemental Determination in Crustacean Samples by MIP OES
Biol Trace Elem Res. 2022 Sep 24. doi: 10.1007/s12011-022-03409-x. Online ahead of print.ABSTRACTA simple procedure for determination of Al, Cr, K, Mg, Mn, and Zn using diluted organic acid in the preparation of shrimp (Macrobrachium amazonicum) and crab samples (Ucides cordatus) was proposed in this study. Determinations were performed using microwave-induced plasma optical emission spectrometer (MIP OES). The contents of elements were evaluated after solubilization of samples in 50% formic acid (v v-1) and subsequent heating in bath with stirring and heating at 90 °C. The accuracy of the proposed procedure was assessed ...

Physiological response and oxidative stress of grass carp (Ctenopharyngodon idellus) under single and combined toxicity of polystyrene microplastics and cadmium
Ecotoxicol Environ Saf. 2022 Sep 21;245:114080. doi: 10.1016/j.ecoenv.2022.114080. Online ahead of print.ABSTRACTThe harm of microplastics (MPs) to aquatic ecosystems is caused by their stable and non-degradable properties. Additionally, the pollutants such as heavy metals in the water are easy to be adsorbed on their surface with their small particle size and large specific surface area, resulting in environmental pollution. Therefore, the study on the mixture toxicity of MPs and heavy metals has theoretical significance for the risk assessment of aquatic ecosystems. In the present study, 10 nm polystyrene (PS) and cadmiu...

Cloning, tissue distribution of desert hedgehog (dhh) gene and expression profiling during different developmental stages of Pseudopleuronectes yokohamae
In this study, we cloned and characterized the dhh gene from Pseudopleuronectes yokohamae. The full-length cDNA of Pydhh comprises 3194 bp, with a 1317 bp open reading frame (ORF) that encodes a polypeptide of 461 amino acids with a typical HH-signal domain, Hint-N and Hint-C domains. Multiple sequence alignment revealed that the putative PyDHH protein sequence was highly conserved across species, especially in the typical domains. Phylogenetic analysis showed that the PyDHH clustered within the Pleuronectiformes. Real-time quantitative PCR showed that Pydhh was detected in fourteen different tissues in adult-female and ad...

Long-term effects of adolescent exposure to olanzapine in C57BL/6  J mice and the impact of dietary fish oil supplementation
ConclusionsThe current results suggest that adolescent olanzapine exposure can produce long-term alterations in weight and metabolic function in male mice and that dietary fish oil can reduce adverse effects of lifelong consumption of an HF-HS diet. Because expected adverse effects of adolescent olanzapine treatment were not observed, the potential beneficial effects of dietary fish oil for SGA-induced weight gain and metabolic dysfunction could not be evaluated.

Adverse effects of herbicides in freshwater Neotropical fish: A review
Aquat Toxicol. 2022 Sep 9;252:106293. doi: 10.1016/j.aquatox.2022.106293. Online ahead of print.ABSTRACTAlthough herbicides have been developed to act on the physiological processes of plants, they are responsible for causing deleterious effects on animals. These chemical compounds are widely used throughout the world, but especially in countries that export agricultural products such as Central and South America, their use has increased in recent years. Aquatic environments are natural reservoirs of herbicides, which after being applied on crops, run off through the soil reaching rivers, lakes, and oceans. Fish are among ...

Effects of < em > cis < /em > -9, < em > trans < /em > -11 and < em > trans < /em > -10, < em > cis < /em > -12 conjugated linoleic acid supplementation on maternal reproductive parameters
Zygote. 2022 Sep 23:1-9. doi: 10.1017/S0967199422000405. Online ahead of print.ABSTRACTConjugated linoleic acid (CLA) is a mixture of positional isomers of linoleic acid found in ruminant products and meat. The diet supplementing with CLA is an emerging area, requiring studies to elucidate its effects on animals and human reproduction, as well as its side effects. Therefore, the aim of this study was to evaluate the effects of CLA gastric administration, during the pregestational and gestational period in biometric and reproductive parameters, as well as in ovarian morphophysiology. Animals were distributed in three groups...

Dr Robert Knox and his book on fishing in Scotland: A window into his mind
J R Coll Physicians Edinb. 2022 Jun;52(2):159-165. doi: 10.1177/14782715221103720. Epub 2022 Jun 17.ABSTRACTRobert Knox was publicly vilified for his suspected complicity in the 16 murders committed by Burke and Hare, although he had no involvement in them. Along with several books on anatomy Knox also wrote a book on angling in Lowland Scotland. In 'Fish and Fishing in the Lone Glens of Scotland' Knox's deep love for nature and for fishing emerges. Most interesting however is that although generally focussed on fish and fishing, the book abounds with asides on Knox's other preoccupations and passions. These provide rare i...

Dissecting the co-segregation probability from genome architecture mapping
In this study, by using a polymer-based model of chromatins, we derive a theoretical expression of the co-segregation probability as well as that of the contact probability, and carry out quantitative analyses of how they differ from each other. The results from our study, validated with in-silico GAM analysis on 3D genome structures from FISH, suggest that to attain strong correlation with the inter-locus distance, a properly normalized version of co-segregation probability needs to be calculated based on a large number of nuclear slices (n>103).PMID:36146938 | DOI:10.1016/j.bpj.2022.09.018 (Source: Biophysical Journal)
