Mussels, oysters and scallops have the highest levels of microplastic contamination among seafood, a new study reveals.
The research - led by researchers at Hull York Medical School and the University of Hull - looked at more than 50 studies between 2014 and 2020 to investigate the levels of microplastic contamination globally in fish and shellfish.
The research group led by Dr Sjoerd van Wijk from the Institute of Experimental Cancer Research in Paediatrics at Goethe University already two years ago found evidence indicating that the anti-diarrhoea drug loperamide could be used to induce cell death in glioblastoma cell lines. They have now deciphered its mechanism of action and, in doing so, are opening new avenues for the development of novel treatment strategies.
When cells digest themselves
Philadelphia, December 21, 2020 - Controlling inflammation after transplantation of organs, cells, or tissues is critical for graft survival; however, it can be difficult. Continuing injuries due to chronic rejection can be particularly problematic.
WASHINGTON, December 22, 2020 -- Cornell University is developing a system to extract energy from cattle manure to meet the campus's peak demands for heat in the winter months. In the Journal of Renewable and Sustainable Energy, by AIP Publishing, scientists involved with the project give a detailed analysis of the issues required to make this work, including scientific, economic, and energy policy considerations.
What The Study Did: Researchers examined the use of COVID-19-specific coding, the transition from legacy coding and the accuracy of the COVID-19-specific code using SARS-CoV-2 polymerase chain reaction (PCR) testing as the reference standard.

What The Viewpoint Says: Observations about health system performance during the COVID-19 pandemic are offered in this Viewpoint, with an emphasis on system cohesion and 2 of 3 levels of health care described earlier by the National Academy of Medicine: health care organizational capabilities and the environment of care.

Pregnant women who are infected with SARS-CoV-2, the virus that causes COVID-19, during the third trimester are unlikely to pass the infection to their newborns, suggests a study funded by the National Institutes of Health. The study followed 127 pregnant women who were admitted to Boston hospitals during the spring of 2020. Among the 64 pregnant women who tested positive for SARS-CoV-2, no newborns tested positive for the virus.
PITTSBURGH, Dec. 22, 2020 - Through small, neighborhood classes, researchers at UPMC Children's Hospital of Pittsburgh and Promundo-US significantly reduced sexual violence among teenage boys living in areas of concentrated disadvantage.
What The Study Did: In this modeling study of simulated adults living in homeless shelters, daily symptom screening with polymerase chain reaction (PCR) testing of individuals who had positive symptom screening paired with management at a nonhospital care site of people with mild to moderate COVID-19 was associated with a substantial decrease in infections and lowered costs over four months compared with no intervention across a wide range of epidemic scenarios.
BOSTON -- Pregnant women may be especially vulnerable to developing more severe cases of COVID-19 following SARS-CoV-2 infection, but little is known about their anti-SARS-CoV-2 immune response or how it may affect their offspring. In a study published in JAMA Network Open, a group led by investigators at Massachusetts General Hospital (MGH) provides new insights that could help improve care for these women and their newborns and emphasizes the need for pregnant women to be considered in vaccine rollout plans.
WASHINGTON, December 22, 2020 -- Over 300,000 people die each year in the U.S. due to sudden cardiac death. In many cases, sudden cardiac death is caused by abnormally rapid heart rhythms called tachycardias, which means the heart cannot pump adequate blood to the body.
In Chaos, by AIP Publishing, researchers use mice to study tachycardias and find there are intrinsic mechanisms that exist in heart tissue that they hypothesize lead to the self-termination of rapid cardiac rhythm.
In many animals, female preference for males with the most elaborate appearance is an important factor in the evolution of bright and dramatic colours.
Females are thought to prefer colourful males because only 'high-quality' males - those with the most resources, superior foraging skills or social status - can produce and maintain the most vibrant colours.
By choosing these high-quality males, females may ensure a good father or good genes for their offspring.
But do high quality males that are preferred by females invest more in their appearance?
What The Study Did: Researchers used data from a large national health insurer in the U.S. to examine whether hospital outcomes for patients with COVID-19 are improving.

Female rats that inhaled vaporized cannabis daily for a month developed a blunted physiological response to stress, according to a new study by Washington State University researchers.
In contrast, male rats that were provided access to the same potency of cannabis over the same 30-day window did not experience any physiological changes in how they responded to a stressful situation.
The results of the study, published in the journal Neurobiology of Stress, indicate there may be significant differences in how chronic cannabis use affects males and females.
Abstract: Atomic force microscopy (AFM) allows to obtain images and movies showing proteins at work, however with limited resolution. The developed BioAFMviewer software opens the opportunity to use the enormous amount of available high-resolution protein data to better understand experiments. Within an interactive interface with rich functionality, the BioAFMviewer computationally emulates tip-scanning of any biomolecular structure to generate simulated AFM graphics and movies. They greatly help in the interpretation of e.g., high-speed AFM observations.
