Rockville, Md. (April 27, 2021)--People who self-report daytime sleepiness were found to have shorter telomeres regardless of whether they had obstructive sleep apnea, according to a new study from researchers at the Mayo Clinic in Rochester, Minnesota. The findings will be presented virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.
Rockville, Md. (April 27, 2021)--Urine analysis of COVID-19 patients revealed elevated levels of specific biomarkers of the immune system compared to those who were not infected with the coronavirus. In addition, levels of these inflammatory markers were higher in patients with comorbidities such as high blood pressure and diabetes, according to researchers from Wayne State University in Detroit. The findings will be presented virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.
Rockville, Md. (April 27, 2021)--Although bronchopulmonary dysplasia (BPD)--a chronic lung disease affecting newborns--is the most common complication of preterm birth, it remains difficult to diagnose and treat. Researchers from Fundación INFANT in Buenos Aires, Argentina, and The University of Oklahoma Health Sciences Center, hope to address these difficulties using machine learning to inform the clinical care of preemies with BPD. The team will present their work virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.
A new study found that non-pungent synthetic analog of capsaicin -- the compound that makes chili peppers hot -- made small cell lung cancer cells more responsive to treatment. Small cell lung cancer is a very aggressive form of cancer with a low survival rate.
Scientists from around the world are gathering to share the latest research at the forefront of biology during the Experimental Biology (EB) 2021 meeting. Many sessions focus on the year's most pressing priorities in bioscience: COVID-19 and the virus that causes it, SARS-CoV-2. Here are five highlights:
Legacy of COVID-19 in blood vessels may raise risk of heart disease
Recent years have brought increased attention to the lasting effects of chemicals we unwittingly inhale, touch and ingest while going about our daily lives. The Experimental Biology (EB) 2021 meeting features the latest research on how environmental exposures affect health. Here are five highlights:
Study sheds light on health hazards of hog farms
Results from a new cell study suggest that the SARS-CoV-2 spike protein can bring about long-term gene expression changes. The findings could help explain why some COVID-19 patients -- referred to as COVID long-haulers -- experience symptoms such as shortness of breath and dizziness long after clearing the infection.
The two major types of cetaceans appear to have evolved their characteristic blowholes through different anatomical transformations, according to a study being presented at the American Association for Anatomy annual meeting during the Experimental Biology (EB) 2021 meeting, held virtually April 27-30.
Using a newly developed mouse model of acute lung injury, researchers found that exposure to the SARS-CoV-2 spike protein alone was enough to induce COVID-19-like symptoms including severe inflammation of the lungs.
SARS-CoV-2, the virus that causes COVID-19, is covered in tiny spike proteins. These proteins bind with receptors on our cells, starting a process that allows the virus to release its genetic material into a healthy cell.
A technology-packed tank top offers a simple, effective way to track astronauts' vital signs and physiological changes during spaceflight, according to research being presented at the American Physiological Society annual meeting during the Experimental Biology (EB) 2021 meeting, held virtually April 27-30.
New research offers an up-close view of how SARS-CoV-2, the virus that causes COVID-19, can spread to the brain. The study helps explain the alarming array of neurological symptoms reported in some patients with COVID-19, as well as why some patients suffer severe neurological effects while others experience none at all.
The researchers report evidence that SARS-CoV-2 can infect both the nerve cells that power our brains (neurons), and the cells in the brain and spinal cord that support and protect neurons (astrocytes).
New insights into how fetal and adult liver cells differ could be used to help make liver cell transplants successful long term. Transplanting functioning liver cells into a patient's liver can help replace liver function that is impaired due to disease.
Today there are many more patients waiting for liver transplants than there are donor organs available. Because liver cell transplantation only requires a portion of cells isolated from a liver, it could allow multiple patients to be treated from one donated organ.
The placenta forms the interface between the maternal and foetal circulatory systems. As well as ensuring essential nutrients, endocrine and immunological signals get through to the foetus to support its development and growth, the placenta must also protect it from the accumulation of potentially toxic compounds. A study from Cécile Demarez, Mariana Astiz and colleagues at the University of Lübeck in Germany now reveals that the activity of a crucial placental gatekeeper in mice is regulated by the circadian clock, changing during the day-night cycle.
OAK BROOK, Ill. - Exercise appears to reduce the long-term risk of bronchiectasis, a potentially serious disease of the airways, according to a study published in the journal Radiology.
Bronchiectasis is characterized by repeated cycles of inflammation and exacerbations that damage the airways, leaving them enlarged, scarred and less effective at clearing mucus. This creates an environment ripe for infections. Risk increases with age and the presence of underlying conditions like cystic fibrosis. There is no cure.
In an effort to determine the potential for COVID-19 to begin in a person's gut, and to better understand how human cells respond to SARS-CoV-2, the scientists used human intestinal cells to create organoids - 3D tissue cultures derived from human cells, which mimic the tissue or organ from which the cells originate. Their conclusions, published in the journal Molecular Systems Biology, indicate the potential for infection to be harboured in a host's intestines and reveal intricacies in the immune response to SARS-CoV-2.
