Controlled Interfacial Tailoring of Hierarchical Silicon Synergizes Charge Transport Enabling Stable and Fast Lithium Storage.

Silicon is a promising anode material candidate but encounters volume change and capacity decay issues. Although diverse demonstrations in structural and interfacial engineering, the performance toward industrial applications remains to be improved. Herein, a controlled interfacial tailoring strategy is proposed for micro-nano hierarchically structured silicon.

Effects of Cryptocaryon irritans infection on the histopathology, oxidative stress, immune response, and intestinal microbiota in the orange-spotted grouper Epinephelus coioides.

Cryptocaryon irritans is a parasitic ciliate of marine fish, causing serious mortality and economic loss of grouper. In this study, the orange-spotted grouper (Epinephelus coioides) were separately exposed to C. irritans infection for 72 h at a dose of 5000 or 10000 active theronts per fish, and we evaluated the changes in histopathology, oxidative stress, immune response, and intestinal microbiota composition.

Mucosal immunoglobulin response in Epinephelus coioides after Cryptocaryon irritans infection.

The teleost mucosal immune system consists mainly of the skin, gills and gut, which play crucial roles in local immune responses against invading organisms. Immunoglobulins are essential molecules in adaptive immunity that perform crucial biological functions. In our study, a mucosal immunity model was constructed in Epinephelus coioides groupers after Cryptocaryon irritans infection, according to previous experience.

Protection of Grouper Against by Immunization With and Protective Cross-Reactive Antigen Identification.

Vaccination is an effective method to prevent infection. Although some vaccines have been developed, large-scale production of these vaccines is costly. Development of a heterogenous vaccine generated by low-cost antigens is an alternative method.

Transcriptomic analysis reveals innate immune mechanisms of an underlying parasite-resistant grouper hybrid (Epinephelus fuscogutatus × Epinephelus lanceolatus).

Hybridization is an artificial breeding strategy for generating potentially desirable offspring. Recently, a novel Hulong grouper hybrid (Epinephelus fuscogutatus × Epinephelus lanceolatus) yielded significant growth superiority over its parent. Improved innate immunity is considered as another desirable feature during hybridization.

Study on the characterization of grouper (Epinephelus coioides) immunoglobulin T and its positive cells.

Immunoglobulins (Igs) play a vital role in the adaptive immunity of gnathostomes. IgT, a particular Ig class in teleost fishes, receives much attention concerning the mucosal immunity. While, the characteristic and function of Epinephelus coioides IgT is still unknown.

Microplastic abundance, distribution and composition in the Pearl River along Guangzhou city and Pearl River estuary, China.

Like many urban rivers, the Pearl River in China is contaminated with microplastics. Compared with marine environments, microplastic pollution in freshwater is less understood, especially in urban rivers. In the present study, the abundance and distribution of microplastics in water from the Pearl River was investigated, including the estuary and the urban section along Guangzhou.
