Titanium dioxide nanoparticles (TiO2 NP) were reported to be reprotoxic in humans and fish. However, the effects of these NP on reproduction marine bivalves, namely oysters, remain unknown. Thus, a short-term (1 h) direct exposure sperm Pacific oyster (Crassostrea gigas) two TiO2 concentrations 10 mg.L-1) was performed, motility, antioxidant responses, DNA integrity evaluated. Although no changes occurred motility activities antioxidants, genetic damage indicator increased at both concentrations, demonstrating that affects sperm. transfer can happen, it does not fulfill its biological mission since transferred is intact may compromise recruitment oysters. This vulnerability C. gigas towards highlights importance studying NPs broadcast spawners.

The biological response to nanomaterials exposure depends on their properties, route of exposure, or model organism. Titanium dioxide nanoparticles (TiO2 NPs) are among the most used nanomaterials; however, concerns related oxidative stress and metabolic effects resulting from ingestion rising. Therefore, in present work, we addressed citrate-coated 45 nm TiO2 NPs combining bioaccumulation, tissue ultrastructure, proteomics approaches gilthead seabream, Sparus aurata Japanese carpet shell, Ruditapes philippinarum. was exposed through artificially contaminated feeds, while R. philippinarum using NPs-doped microalgae solutions. accumulation titanium fish liver is associated with alterations hepatic structure, alteration expression proteins lipid fatty acid metabolism, breakdown for energy, transport, homeostasis. While cellular structure were less affected than atypical gill cilia microvilli metabolic-related also observed bivalve. Overall, feeding appear stem various interactions cells, involving key proteins, changes cell membranes, structures, organelles. possible appearance disorders environmental risks aquatic organisms posed by deserve further study.

Silver nanoparticles and silver ions indistinguishably decrease sperm motility in Pacific oysters (Magallana gigas) after short-term direct exposure

Environmental Toxicology and Pharmacology, Год журнала: 2023, Номер 101, С. 104202 - 104202

The present study aimed to evaluate the reprotoxicity of environmental (0.25 μg.L-1) and supra-environmental (25 μg.L-1 250 levels silver nanoparticles (Ag NP) on Pacific oyster (Magallana gigas), by determining sperm quality. For that, we evaluated motility, mitochondrial function oxidative stress. To determine whether Ag toxicity was related NP or its dissociation into ions (Ag+), tested same concentrations Ag+. We observed no dose-dependent responses for Ag+, both impaired motility indistinctly without affecting inducing membrane damage. hypothesize that is mainly due adhesion membrane. Blockade ion channels may also be a mechanism which Ag+ induce toxicity. presence in marine ecosystem concern as it affect reproduction oysters.

Exposure to silver and titanium dioxide nanoparticles at supra-environmental concentrations decreased sperm motility and affected spermatozoa subpopulations in gilthead seabream, Sparus aurata

Fish Physiology and Biochemistry, Год журнала: 2023, Номер 50(5), С. 1959 - 1970

Abstract Marine pollution by nanoparticles (NPs) can be reprotoxic for fish and disturb successful reproduction of wild populations. In gilthead seabream ( Sparus aurata ), a mild effect on sperm motility was observed after exposure to high concentrations silver NPs. Considering the great heterogeneity traits within sample, it is possible that NPs affect spermatozoa accordingly, modulating subpopulation profile. Thus, this work aimed analyse NP effects in general considering population structure, using approach. Seabream samples from mature males were exposed 1 h increasing titanium dioxide (1, 10, 100, 1000 10,000 μg L −1 ) (0.25, 25 250 NPs, including Ag + , dissolved non-activating medium (0.9 % NaCl). Concentrations chosen include realistic (10–100 0.25 respectively, TiO 2 Ag) supra-environmental values. The mean particle diameter determined as 19.34 ± 6.72 21.50 8.27 nm stock suspension, silver. After ex vivo exposure, parameters computer-assisted analysis, subpopulations later identified two-step cluster analysis. Results revealed significant reduction total highest while curvilinear straight-line velocities not altered. Exposure (Ag lowered significantly progressive motilities at all concentrations, lower only concentration. Sperm also affected both cases, levels triggered decrease percentage fast (38.2% 34.8.% 45.0% vs 53.4% control), an increase slow subpopulations. A proven but concentrations.

Nanoparticles occur in our natural habitats due to biological, physical and chemical processes. nanomaterials are increasingly used food packaging, textiles, electronics, biomedicine, cosmetics (lipstick, sunscreen, etc.), many aspects of daily life. Therefore, the potential risk exposure humans surrounding organisms nanoparticles should not be ignored. Nanomaterials materials with small dimensions large surface area, as well other properties, such polluting metals charged surfaces, genotoxic properties. Because these they can cause mutations damage chromosomes. It is required consider influence only on but also genetic components species environment. Recently, adverse effects from reproductive system have emerged, creating toxicity. Reproductive toxicity refers that affect development healthy embryos, cycle, any stage pregnancy.

Animals' reduced fertility poses a serious threat to animal reproduction. A number of factors have been demonstrated reduce semen quality, including age, health, heredity, nutritional condition, seasonal variance, travel stress, artificial insemination (AI), and rising breeding demand. The properties functioning are altered by the in vitro environment changes after collection that occur during insemination. Successful may also be achieved via use sperm selection purification techniques. Invasive labeling and/or centrifugation processes often used current manipulation approaches, which harmful result poor recovery rates. biochemical DNA status disregarded favor selecting for physically normal motile sperm. It is critical develop alternative, noninvasive, label-free methods separate based on features status. Magnetic nanoparticles provide intriguing new research opportunities selection. This book explains how tagged cleaned up with nanotechnology, has become more important this area recent years. analyzes impact nanotechnology labeling, selection, techniques, both existing planned.
