Exploring the second intermediate hosts and morphology of human- and cat-specific Opisthorchis viverrini-like populations
Int J Parasitol. 2024 Apr 17:S0020-7519(24)00076-6. doi: 10.1016/j.ijpara.2024.04.006. Online ahead of print.ABSTRACTInfection by the zoonotic fish-borne trematode, Opisthorchis viverrini, remains a crucial health issue in Thailand and neighboring countries. Recently, molecular analysis revealed two populations of putative O. viverrini: one found primarily in human hosts ("human-specific" population) and the other primarily in cats ("cat-specific" population). It is unclear how the infective stages (metacercariae) of these different populations circulate among definitive and reservoir hosts in nature. To gain an insight in...

Sensors, Vol. 24, Pages 2606: On the Initialization of Swarm Intelligence Algorithms for Vector Quantization Codebook Design
o Madeiro Vector Quantization (VQ) is a technique with a wide range of applications. For example, it can be used for image compression. The codebook design for VQ has great significance in the quality of the quantized signals and can benefit from the use of swarm intelligence. Initialization of the Linde–Buzo–Gray (LBG) algorithm, which is the most popular VQ codebook design algorithm, is a step that directly influences VQ performance, as the convergence speed and codebook quality depend on the initial codebook. A widely used initialization alternative is random initialization, in which the ...

Repeated Divergence in Opsin Gene Expression Mirrors Photic Habitat Changes in Rapidly Evolving Crater Lake Cichlid Fishes
Am Nat. 2024 May;203(5):604-617. doi: 10.1086/729420. Epub 2024 Mar 15.ABSTRACTAbstractSelection pressures differ along environmental gradients, and traits tightly linked to fitness (e.g., the visual system) are expected to track such variation. Along gradients, adaptation to local conditions might be due to heritable and nonheritable environmentally induced variation. Disentangling these sources of phenotypic variation requires studying closely related populations in nature and in the laboratory. The Nicaraguan lakes represent an environmental gradient in photic conditions from clear crater lakes to very turbid great lake...

Evolutionary affinities and morphological characterization of the enigmatic Zonocotyle bicaecata (Trematoda: Paramphistomoidea: Zonocotylidae) from the Upper Paran á River basin
Syst Parasitol. 2024 Apr 18;101(3):30. doi: 10.1007/s11230-024-10158-z.ABSTRACTNeotropical fish amphistomes represent a highly diverse group within the Paramphistomoidea, with wide distribution across major South American hydrological drainages. However, the limited molecular characterization of these taxa has impeded a comprehensive assessment of their evolutionary relationships and the systematic relevance of morphological features in classification schemes. Our study, based on the critical evaluation of the type material of both nominal species of Zonocotyle (type genus of the monotypic Zonocotylidae), and newly collect...

Galectin-8-like isoform X1 mediates antibacterial, antiviral, and antioxidant responses in red-lip mullet (Planiliza haematocheilus) through positive modulation of pro-inflammatory cytokine, chemokine, and enzymatic antioxidant activity
This study identified Galectin-8-like isoform X1 (PhGal8X1) from red-lip mullet (Planiliza haematocheilus) and investigated its role in regulating fish immunity. The open reading frame of PhGal8X1 was 918bp, encoding a soluble protein of 305 amino acids. The protein had a theoretical isoelectric (pI) point of 7.7 and an estimated molecular weight of 34.078 kDa. PhGal8X1 was expressed in various tissues of the fish, with prominent levels in the brain, stomach, and intestine. PhGal8X1 expression was significantly (p<0.05) induced in the blood and spleen upon challenge with different immune stimuli, including polyinosinic:...

Fish ubiquitin-specific protease 8 (USP8) inhibits IFN production through autophagy-lysosomal dependent degradation of IRF7
In this study, we report that zebrafish ubiquitin-specific protease 8 (USP8) promotes IRF7 degradation through an autophagy-lysosome-dependent pathway to inhibit IFN production. First, zebrafish usp8 is induced upon spring viremia of carp virus (SVCV) infection and polyinosinic/polycytidylic acid (poly I:C) stimulation. Second, overexpression of USP8 suppresses SVCV or poly I:C-mediated IFN expression. Mechanistically, USP8 interacts with IRF7 and promotes its degradation via an autophagy-lysosome-dependent pathway. Finally, USP8 significantly suppresses cellular antiviral responses and enhances SVCV proliferation. In summ...

Decoding the molecular phylogenetics of ornamental catfishes (siluriformes) of North East India using DNA barcoding approach
CONCLUSIONS: In this study, the maximum intraspecific genetic distance of 0.03 and the minimum interspecific genetic distance of 0.14 were observed among the species. Therefore, it is evident that there is a barcoding gap among the species, which helped in the correct identification of the species. Thus, DNA barcoding helped complement the phenetic approach and also revealed a different phylogenetic relationship among the catfishes belonging to the Bagridae family.PMID:38637345 | DOI:10.1007/s11033-024-09487-5 (Source: Molecular Biology Reports)

Assessing the impact of COVID-19 era drug combinations on hepatic functionality: A thorough investigation in adult Danio rerio
Environ Pollut. 2024 Apr 16;349:123997. doi: 10.1016/j.envpol.2024.123997. Online ahead of print.ABSTRACTCurrent and thorough information on the ecotoxicological consequences of pharmaceuticals is accessible globally. However, there remains a substantial gap in knowledge concerning the potentially toxic effects of COVID-19 used drugs, individually and combined, on aquatic organisms. Given the factors above, our investigation assumes pivotal importance in elucidating whether or not paracetamol, dexamethasone, metformin, and their tertiary mixtures might prompt histological impairment, oxidative stress, and apoptosis in the ...

Halogenated aromatic pollutants in routine animal-derived food of South China: Occurrence, sources, and dietary intake risks
Environ Pollut. 2024 Apr 16:124002. doi: 10.1016/j.envpol.2024.124002. Online ahead of print.ABSTRACTHalogenated aromatic pollutants (HAPs) including polychlorinated dibenzo-p-dioxins/furans (PCDD/Fs), polychlorinated biphenyls (PCBs), polybrominated dibenzo-p-dioxins/furans (PBDD/Fs), and polybrominated diphenyl ethers (PBDEs) exhibit diverse toxicities and bio-accumulation in animals, thereby imposing risks on human via animal-derived food (ADF) consumption. Here we examined these HAPs in routine ADFs from South China and observed that PBDEs and PCBs showed statistically higher concentrations than PCDD/Fs and PBDD/Fs. PC...
