The long-term ecological risk of synthetic organic contaminants, exclusively endocrine disrupting chemicals (EDCs) such as phthalates has threatened reclaimed seawater quality in marine environment. In this study, environmental distributions of 14 phthalic acid esters (PAEs) in seawater, and biota (fish and crab) across Thane Creek, Mumbai India is reported. Identification and quantifications of phthalates in environmental matrices was carried out using GC-MS technique. Abundance of phthalates in each matrix was discussed and compared with literature value. Total phthalate esters concentrations in seawaters, fish and crab samples were found to be 104.8 ± 37.8 μg L, 113 ± 36.4 μg g and 155 ± 38 μg g (dry weight) respectively. Di-n-butylphthalate (DBP) was most abundant compound among analyzed PAEs in all tested aquatic media. In situ bio-concentration factors (BCFs) were calculated for all monitored phthalates in fish and crabs and compared with log K values. Risk quotient and estradiol equivalent concentration were also calculated to evaluate ecological risk and estrogenic potential of seawater in terms of DBP and di (2-ethylhexyl) phthalate. The average values of total PAEs daily intake were calculated as 58.1 ± 13.6 and 79.6 ± 19.6 (µg kg-bw/day) for fish and crab respectively in an adult population.

Climate warming and frequent incidents of extreme high temperatures are serious global concerns. Heat stress induced by high temperature has many adverse effects on animal physiology, especially in aquatic poikilotherms. Chinese mitten crab (Eriocheir sinensis) is sensitive to high temperatures, this study evaluated the harmful effects of heat stress on the neurotoxicity, intestinal health, microbial diversity, and metabolite profiles.

In animals, growth and development are strongly correlated with the gut microbiota. The gut of the economically important marine crab () harbors a diverse microbial community, yet its associations with the surrounding environment, growth performance, and developmental stages remain obscure. In this study, we first characterized stage-specific microbiomes and shifts in the contributions of live feed and water via SourceTracker.

Background: Chronic kidney disease (CKD) is prevalent among elderly patients with type 2 diabetes mellitus (T2DM). The association between dietary patterns and CKD in elderly T2DM patients remains understudied. This study aimed to investigate the relationship between dietary patterns and CKD in elderly Chinese patients with T2DM.

The present study investigated the changes of expression and localization of PtVg mRNA, tissue Vg/ Vn concentrations, the contents of progesterone and 17ß-estradiol during the ovarian development of P. trituberculatus. The results showed that: 1) The most abundant mRNA levels of PtVg were found in stage IV, and hepatopancreatic PtVg mRNA was markedly greater than that in ovaries from stage II to stage V.

High-latitude ocean basins are the most productive on earth, supporting high diversity and biomass of economically and socially important species. A long tradition of responsible fisheries management has sustained these species for generations, but modern threats from climate change, habitat loss, and new fishing technologies threaten their ecosystems and the human communities that depend on them. Among these species, Alaska's most charismatic megafaunal invertebrate, the red king crab, faces all three of these threats and has declined substantially in many parts of its distribution.
