Effects of nanoplastics on energy metabolism in the oriental river prawn (Macrobrachium nipponense)

Environmental Pollution, 2021
Nanoplastics are common pollutants in aquatic environments and have attracted widespread research attention. However, few studies focus on the effects of nanoplastic exposure on energy metabolism in crustaceans. Accordingly, we exposed juvenile oriental river prawns (Macrobrachium nipponense) to different concentrations of 75-nm polystyrene ...

Effects of nanoplastic on cell apoptosis and ion regulation in the gills of Macrobrachium nipponense

Environmental Pollution, 2022
Nanoplastic, ubiquitous in aquatic environments, are raising concern worldwide. However, studies on nanoplastic exposure and its effects on ion transport in aquatic organisms are limited. In this study, the juvenile oriental river shrimp, Macrobrachium nipponense, was exposed to five levels of nanoplastic concentrations (0, 5, 10, 20, 40 mg/L) in order

Identification and characterization of a Toll-like receptor gene from Macrobrachium nipponense

Fish & Shellfish Immunology, 2021
Outbreaks of infectious disease in shrimp pose a serious threat to shrimp agriculture worldwide. Shrimp lack adaptive immunity and depend only on innate immunity as a defense system against infectious disease. Toll-like receptors (TLR) are reported to play a critical role in the innate immune system.

Pond culture of the freshwater prawn Macrobrachium nipponense in China.

2020
Abstract In China, conditioning of freshwater prawn (Macrobrachium nipponense) broodstock is conducted in earthen ponds at a density of 45-60 g m-2, at a ratio of 3-4 females to 1 male (Liu, 2004). Mixed feed and fresh food of animal origin are used for broodstock. Mating occurs when temperature rises above 18°C.

Twelve polymorphic microsatellites in Oriental river prawn, Macrobrachium nipponense

Molecular Ecology Resources, 2008
AbstractOriental river prawn, Macrobrachium nipponense, is a commercially important freshwater prawn species in China, Japan, Korea and Vietnam. Due to overfishing for food, the wild stocks M. nipponense are endangered. Twenty microsatellite loci were isolated from the M. nipponense. Twelve of these loci were polymorphic (seven to 16 alleles per locus),

Identification of a ficolin involved in ovary reproductive immunity in Macrobrachium nipponense

Fish & Shellfish Immunology
Recent studies have revealed that the ovary plays a crucial role in defending against pathogen infection in crustaceans, yet the underlying molecular mechanisms remain poorly understood. Our previous work identified numerous genes responsive to poly I:C challenge in the ovary of Macrobrachium nipponense, including several members of the fibrinogen ...

Toxicokinetics of microplastics in Macrobrachium nipponense and their impact on the bioavailability of loaded pollutants

Journal of Hazardous Materials
Microplastics (MPs) have unique toxicokinetic (TK) processes that differ from those of soluble pollutants. This study investigated the ingestion, migration, accumulation, and clearance of environmental aging MPs in the Japanese swamp shrimp (Macrobrachium nipponense).

Involvement of a TNF homologue in balancing the host immune system of Macrobrachium nipponense

International Journal of Biological Macromolecules, 2019
In vertebrates, tumor necrosis factors (TNFs) are well-known cytokines involved in a diversity of physiological and pathological events. In the present work we identified a novel TNF-like gene (MnTNF) from Macrobrachium nipponense, which codes for a protein sharing detectable sequence identify (26-27%) to the mammalian TNFSF members, TWEAK and EDA ...

Polystyrene nanoplastics decrease molting and induce oxidative stress in adult Macrobrachium nipponense

Fish & Shellfish Immunology, 2022
The widespread occurrence and accumulation of plastic waste have been globally recognized as a critical issue. However, few researches have evaluated the adverse effects of nanoplastics to freshwater organisms. Thus, here, the effects of polystyrene nanoplastics (PS-NP) on the physiological changes (i.e., molting) and enzyme activity of oxidative ...

[Accumulation and distribution of lead in Macrobrachium nipponense].

Ying yong sheng tai xue bao = The journal of applied ecology, 2004
The accumulation and distribution of lead granules in the major organs of Macrobrachium nipponense were studied by means of histochemistry, transmission electron microscope (TEM) and atomic absorption spectrophotometer (AAS) analysis. The results showed that many high electronic dense lead granules (EDG) were found primarily in the antennal gland of ...
