Unearthed genetic sequences from China market may point to animal origin of COVID-19
A scientific sleuth in France has identified previously undisclosed genetic data from a food market in Wuhan, China, that she and colleagues say support the theory that coronavirus-infected animals there triggered the COVID-19 pandemic. Several of the researchers presented their findings on Tuesday to the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), an expert group convened last year by the World Health Organization.
“The data does point even further to a market origin,” says Kristian Andersen, an evolutionary biologist at Scripps Research who attended the meeting and is one of the scienti...

Seafood consumption as a source of exposure to high production volume chemicals: A comparison between catalonia and the Canary Islands
Food Chem Toxicol. 2023 Mar 14:113729. doi: 10.1016/j.fct.2023.113729. Online ahead of print.ABSTRACTSeafood plays an important role in diet because of its health benefits. However, the fact that chemical compounds such as high production volume chemicals may be present in seafood means that its consumption can be a potential risk for population. To assess the occurrence of HPVs and estimate the exposure and risk associated with their consumption, specimens of the most consumed seafood species in Catalonia and the Canary Islands, Spain, were collected and analysed. Results showed higher levels of HPVs in samples from Catal...

Occurrence, bioconcentration, and human health risks of pharmaceuticals in biota in the Sea of Marmara, T ürkiye
Chemosphere. 2023 Mar 8:138296. doi: 10.1016/j.chemosphere.2023.138296. Online ahead of print.ABSTRACTThe presence, bioconcentration, and health risk via seafood consumption of 11 pharmaceutical compounds belonging to different therapeutic groups (anti-inflammatory, antiepileptic, lipid regulators, and hormones) were investigated in the muscle tissues of fish and the meat of shrimp in the Sea of Marmara. Six biota species (Merlangius merlangus, Trachurus meditterraneus, Serranus hepatus, Pomatomus saltatrix, Parapenaeus longirostris, Spratus sprattus) were collected from the five stations in October and April 2019.

A ratiometric fluorescent tag based on dual-emissive hydrophobic carbon dots for in-situ monitoring of seafood freshness
Anal Chim Acta. 2023 Apr 15;1250:340931. doi: 10.1016/j.aca.2023.340931. Epub 2023 Feb 1.ABSTRACTA ratiometric fluorescent tag based on dual-emissive hydrophobic carbon dots (H-CDs) with well volatile base nitrogens (VBNs)-response was fabricated, offering the in-situ, real-time, and visual evaluation of seafood freshness. The presented H-CDs aggregates exhibited a sensitive response to VBNs, with a limit of detection of 7 μM and 137 ppb for spermine and ammonia hydroxide, respectively. Subsequently, a ratiometric tag was successfully fabricated by depositing dual-emissive CDs on cotton paper. Upon the treatment with ammo...

Biomarkers of seafood intake during pregnancy - Pollutants versus fatty acids and micronutrients
In conclusion, elevated concentrations of erythrocyte mercury and urinary arsenobetaine can be useful indicators of seafood intake, more so than the n-3 LCPUFAs. However, the relative importance of the biomarkers may differ depending on the type and amount of seafood consumed.PMID:36878269 | DOI:10.1016/j.envres.2023.115576 (Source: Environmental Research)

Biogenic selenium nanoparticles: trace element with promising anti-toxoplasma effect
Pathog Glob Health. 2023 Mar 5:1-16. doi: 10.1080/20477724.2023.2186079. Online ahead of print.ABSTRACTToxoplasmosis is an opportunistic infection caused by the coccidian Toxoplasma gondii which represents a food and water contaminant. The available chemotherapeutic agents for toxoplasmosis are limited and the choice is difficult when considering the side effects. Selenium is an essential trace element. It is naturally found in dietary sources, especially seafood, and cereals. Selenium and selenocompounds showed anti-parasitic effects through antioxidant, immunomodulatory, and anti-inflammatory mechanisms. The present stud...
