Study finds link between racial, socioeconomic factors and atrial fibrillation treatment

2021-02-26
PHILADELPHIA-- Even though the use of rhythm control strategies for treating Paroxysmal Atrial Fibrillation (AF), a common abnormal heart rhythm, have increased overall in the United States, patients from racial and ethnic minority groups and those with lower income were less likely to receive rhythm control treatment - often the preferred treatment - according to new research from the Perelman School of Medicine at the University of Pennsylvania. The study is published in the JAMA Network Open. "Research has demonstrated the pervasive impact of structural racism on health outcomes among minoritized patients. We know, for instance, that there is less use of novel cardiovascular therapies among Black, Latinx, and patients of lower socioeconomic ...

Finding their comfort zone

Finding their comfort zone
2021-02-26
A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy. Jeff Moran, an assistant professor of mechanical engineering in the Volgenau School of Engineering, and colleagues from the University of Washington in Seattle studied self-propelled half-platinum/half-gold rods that "swim" in water using hydrogen peroxide as a fuel. The more peroxide there is, the faster the swimming; without peroxide in pure water, the rods don't swim. In this work, they set out to understand ...

Genes identified that increase the risk of obesity but also protect against disease

2021-02-26
People living with obesity tend to have unhealthy glucose and lipid levels in their blood, as well as high blood pressure. As a result, they are more at risk of cardiovascular and metabolic diseases. But scientists have observed that up to 45% of people living with obesity have healthy blood pressure and glucose and lipid levels, and therefore may not be at high risk of disease. The reason why this group of people with obesity remain healthy, has been poorly understood. But now a team of researchers - led by scientists at the University of Copenhagen and Icahn School of Medicine ...

Biologists from RUDN University suggested a new substance to suppress neuroinflammation

Biologists from RUDN University suggested a new substance to suppress neuroinflammation
2021-02-26
Biologists from RUDN University confirmed that a well-known spasmolytic drug called hymecromone can suppress the inflammatory response in astrocytes, important glial cells of the central nervous system. Potentially, it could be used to develop medications against Alzheimer's disease and other neurodegenerative conditions. The results of the study were published in the International Journal of Molecular Sciences. All pathological processes in the nervous system, such as neurodegenerative diseases, injuries, or intoxications, are associated with inflammations. ...

Pesticide imidacloprid threatens future for key pollinator

Pesticide imidacloprid threatens future for key pollinator
2021-02-26
An insecticide used to control pest infestations on squash and pumpkins significantly hinders the reproduction of ground-nesting bees -- valuable pollinators for many food crops, a new University of Guelph study has revealed. This first-ever study of pesticide impacts on a ground-nesting bee in a real-world context found female hoary squash bees exposed to imidacloprid dug 85 per cent fewer nests, collected less pollen from crop flowers and produced 89 per cent fewer offspring than unexposed bees. "Because they're not making nests and not collecting pollen, they cannot raise offspring," said Dr. Susan Willis Chan, a post-doc in the School of ...

A weak heart makes a suffering brain

2021-02-26
Heart problems cause disturbed gene activity in the brain's memory center, from which cognitive deficits arise. Researchers at the German Center for Neurodegenerative Diseases (DZNE), the University Medical Center Göttingen (UMG) and the German Center for Cardiovascular Research (DZHK) come to this conclusion based on laboratory studies. They consider that they have found a possible cause for the increased risk of dementia in people with heart problems. In mice, a specific drug which is known to affect gene activity alleviated the mental deficits. The involved experts see these results as potential approaches for therapies. ...

Bioinformatics tool accurately tracks synthetic DNA

Bioinformatics tool accurately tracks synthetic DNA
2021-02-26
HOUSTON - (Feb. 26, 2021) - Tracking the origin of synthetic genetic code has never been simple, but it can be done through bioinformatic or, increasingly, deep learning computational approaches. Though the latter gets the lion's share of attention, new research by computer scientist Todd Treangen of Rice University's Brown School of Engineering is focused on whether sequence alignment and pan-genome-based methods can outperform recent deep learning approaches in this area. "This is, in a sense, against the grain given that deep learning approaches have recently outperformed traditional approaches, such as BLAST," he said. "My goal with this study is to start a conversation about how to combine the expertise of both domains to achieve further improvements for this important computational ...

Maternal instincts lead to social life of bees

Maternal instincts lead to social life of bees
2021-02-26
TORONTO, Feb. 26, 2021 - The maternal care of offspring is one of the behavioural drivers that has led some bee species to have an ever-expanding social life over the history of evolution, new research out of York University has found. By virtue of being in a social group, the genome itself may respond by selecting more social rather than non-social genes. The behaviour and social environment come first, setting the stage for future molecular evolution. In addition, the researchers have found that a similar genetic evolution happened independently in different species at different times, suggesting there is a unifying principle leading to the same social trait. "There seems to be something about sociality specifically that is driving the genome to evolve in this way. It's a very ...

Advanced practice nurses reduce hospitalizations from nursing home residents

Advanced practice nurses reduce hospitalizations from nursing home residents
2021-02-26
COLUMBIA, Mo. -- Marilyn Rantz still remembers the day she got the call that her mother, whose health had been declining, had fallen and fractured her shoulder. After rushing to the hospital, her mother told her she didn't understand how she ended up on a helicopter pad after the traumatic incident. A nearby nurse told Rantz the noise from the MRI scanning tube had caused her frightened mother to mistakenly believe she had been airlifted to the hospital on a helicopter. Determined to prevent avoidable hospitalizations, as well as the stress and panic that often comes along with the ambulance ride, Rantz, ...

Early PDA closure may improve outcomes in preterm infants

2021-02-26
MEMPHIS, Tenn. - Extremely low birth weight (ELBW) infants with moderate to large patent ductus arteriosus (PDA) may benefit from transcatheter PDA closure (TCPC) in the first four weeks of life, according to research published by Le Bonheur Cardiologist Ranjit Philip, MD, and Medical Director of Interventional Cardiac Imaging and Interventional Catheterization Laboratory Shyam Sathanandam, MD. Early PDA closure may prevent early onset pulmonary vascular disease, promote growth and facilitate faster weaning off supplemental oxygen and ventilator support. "The primary objective of this study was to describe changes in hemodynamics, ...
