Heavy Metal and Trace Element Levels in Hair Samples from Fishermen in Turkey: The Fish/Ermen Heavy Metal Study (FHMS)
Biol Trace Elem Res. 2023 Apr 4. doi: 10.1007/s12011-023-03653-9. Online ahead of print.ABSTRACTToxic chemicals from polluted seas can enter the human body through seafood consumption and cause health problems. The aim of this study was to evaluate the levels of selected heavy metals and trace elements among fishermen who frequently consumed seafood and controls who consumed seafood less frequently in four provinces on the shores of the Sea of Marmara, which is heavily polluted by industrial activities. Fourteen elements (antimony, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, selenium, stront...

Ultrasound-assisted blue light killing Vibrio parahaemolyticus to improve salmon preservation
This study aims to investigate the effect of BL on V. parahaemolyticus in culture media and in ready-to-eat fresh salmon, and to evaluate the killing effectiveness of the UF combined with BL treatment on V. parahaemolyticus. The results showed that BL irradiation at 216 J/cm2 was effective in causing cell death (close to 100%), cell shrinkage and reactive oxygen species (ROS) burst in V. parahaemolyticus. Application of imidazole (IMZ), an inhibitor of ROS generation, attenuated the cell death induced by BL, indicating that ROS were involved in the bactericidal effects of BL on V. parahaemolyticus. Furthermore, UF for 15 m...

Curr Pharm Biotechnol. 2023 Mar 31. doi: 10.2174/1389201024666230331115338. Online ahead of print.ABSTRACTBromelain is a protein digestive enzyme obtained from the extract of pineapple (steam, fruit, and leaves). It is a cocktail of several thiol endopeptidases and other components like peroxidase, cellulase, phosphatase, and several protease inhibitors. It is a glycoprotein with an oligosaccharide in its molecular structure that contains xylose, fucose, mannose, and N-acetyl glucosamine.

Dispute simmers over who first shared SARS-CoV-2 ’s genome
When GISAID, the widely used database for influenza and SARS-CoV-2 genomes,
issued a statement
last week about a set of controversial sequences from the Huanan Seafood Wholesale Market in Wuhan, China, the release explained by way of background that the repository was “an essential contributor to global health” trusted by thousands of data contributors from 215 nations and territories. But GISAID also included a claim that has been puzzling and infuriating some virologists for 3 years: It was the place where the first SARS-CoV-2 genomes were publicly shared, on 10 January 2020.
That claim challenges con...

China is cracking down on its wildlife trade. Is it enough?
For years, scientists and conservationists have urged China’s government to crack down on a thriving trade in wild animals that they say both threatens the nation’s rich biodiversity and increases the risk that a dangerous disease will jump from wildlife to humans. Now, some of those pleas are being answered: On 1 May, officials will begin to enforce
a strengthened Wildlife Protection Law
that, together with other recent rules, expands China’s list of protected species and criminalizes the sale or consumption of meat from certain animals—including raccoon dogs—known to harbor viruses that can infect hum...

High fish intake rich in n-3 polyunsaturated fatty acids reduces cardiovascular disease incidence in healthy adults: The ATTICA cohort study (2002-2022)
Conclusion: High intake of seafood, and particularly small fish rich in n-3 fatty acids, was associated with a lower risk of 10-year fatal and non-fatal CVD. Thus, public health interventions aimed at enhancing small fish consumption may most effectively deter long-term CVD outcomes, particularly among low risk normotensive individuals.

Mutation behind night blindness in humans helps whale sharks see in the dark
Even a fisher’s yarn would sell a whale shark short. These fish—the biggest on the planet—stretch up to 18 meters long and weigh as much as two elephants. The superlatives don’t end there: Whale sharks also have one of the longest vertical ranges of any sea creature, filter feeding from the surface of the ocean to nearly 2000 meters down into the inky abyss.
Swimming between bright surface waters and the pitch black deep sea should strain the shark’s eyes, making their lifestyle impossible. But researchers have now uncovered the genetic wiring that prevents this from happening.
The study, published th...

Plasma and rectal mucosal oxylipin levels during aspirin and eicosapentaenoic acid treatment in the seAFOod polyp prevention trial
There is evidence that aspirin and the omega-3 polyunsaturated fatty acid (PUFA) C20:5n-3 eicosapentaenoic acid (EPA) have chemopreventative activity against colorectal cancer (CRC) [1,2]. However, the mechanism(s) of the anti-CRC activity of both agents remains unclear with several cyclooxygenase (COX)-dependent and -independent mechanisms being described, based largely on data from in vitro CRC cell studies and rodent CRC models [1,2].

A new pandemic origin report is stirring controversy. Here are key takeaways
Last week, journalists rushed to report on previously undisclosed genetic evidence that mammals sold at the Huanan Seafood Wholesale Market in Wuhan, China—possibly raccoon dogs—might have sparked the COVID-19 pandemic. But to the chagrin of the researchers
who conveyed their findings confidentially to a World Health Organization (WHO) advisory group
on 14 March, the news broke before they had finished analyzing the data, which consist of RNA and DNA sequences collected at the market in early 2020. Yesterday, however, they posted their complete 22-page
report
on Zenodo, an open repository of scienti...

Rat tight junction proteins are disrupted after subchronic exposure to okadaic acid
Environ Sci Pollut Res Int. 2023 Mar 20. doi: 10.1007/s11356-023-26471-x. Online ahead of print.ABSTRACTOkadaic acid (OA), a lipophilic phycotoxin distributed worldwide, causes diarrheic shellfish poisoning and even leads to tumor formation. Currently, the consumption of contaminated seafood is the most likely cause of chronic OA exposure, but there is a serious lack of relevant data. Here, the Sprague-Dawley rats were exposure to OA by oral administration at 100 µg/kg body weight, and the tissues were collected and analyzed to assess the effect of subchronic OA exposure. The results showed that subchronic OA administrati...
