Antioxidant plasma activities of ascorbate, alpha-tocopherol and glutathione peroxidase were analysed in adult male sea bass, Dicentrarchus labrax, in normal conditions and after hypoxia-recovery. In addition, tank measurements of temperature, pH, salinity and chlorine changes were carried out. Ascorbate and alpha-tocopherol were measured using a high-pressure liquid chromatography method and glutathione peroxidase activity enzymatically. Ascorbate and alpha-tocopherol showed a relationship with the velocity of body growing in normal and hypoxia-recovery conditions. In sea bass exposed to hypoxia, only ascorbate and alpha-tocopherol levels were significantly lower compared with the control group. Slope study and expression percent of antioxidants reduction after stress conditions revealed a predominant role of plasma alpha-tocopherol. Sea bass subjected to variations of salinity and chlorine showed a significant decrease in plasma alpha-tocopherol. A relationship could be suggested between antioxidant defence and fish response in aquaculture.

Background: NIAGADS is a national genomics data repository that facilitates access of genotypic and sequencing data to qualified investigators for the study of the genetics of Alzheimer's disease (AD) and related neurological diseases. Collaborations with large consortia and centers such as the Alzheimer's Disease Genetics Consortium (ADGC), Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium, the Alzheimer's Disease Sequencing Project (ADSP), and the Genome Center for Alzheimer's Disease (GCAD) allow NIAGADS to lead the effort in managing large AD datasets that can be easily accessed and fully utilized by the research community.
Method: NIAGADS is supported by the National Institute on Aging (NIA) under a cooperative agreement.

Ecosystem restoration has historically been viewed as an ecological endeavor, but restoration possesses significant, yet largely untapped, potential as a catalyst for personal and social transformation. We highlight the opportunity for restoration to enhance community resilience by increasing agency and collective action and countering the pervasive perception that we are powerless witnesses to environmental decline. In this perspective, we take a "bright spots" approach and highlight successful examples of ecosystem restoration that have helped to nurture a sense of place, foster optimism, and cultivate stronger and more diverse social networks.

Largemouth bass (Micropterus salmoides) has become one of the most important freshwater economic fish farmed almost all over China in recent years. At the same time, the increasing outbreaks of diseases in its aquaculture process have caused substantial economic losses to this industry. However, at present, the genetic basis of disease resistance, including resistance against Aeromonas veronii infection, in largemouth bass is very limited.

The potential risk posed by infectious agents (IAs) associated with netpen aquaculture to wild fishes is determined based on the "release" of IAs from netpens into the environment, the "exposure" of the wild fish to those released agents, and the "consequence" for wild fish experiencing infection by those agents. Information available to characterize these three factors is often lacking, and the occurrence of transmission from aquaculture to wild fish as well as potential consequences of such transmission are difficult to observe. In this study, we utilized environmental DNA (eDNA) to characterize the release of dozens of IAs from, and exposure of Pacific salmon to, Atlantic salmon aquaculture.
