Coronary angiography video interpolation methods to reduce x-ray exposure frequency

2021-06-16
(Press-News.org) In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2021.0011, Xiao-lei Yin, Dong-xue Liang, Lu Wang, Jing Qiu, Zhi-yun Yang, Jian-zeng Dong and Zhao-yuan Ma from Tsinghua University, Beijing, China; Capital Medical University, Beijing, China and The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China analyse coronary angiography video interpolation methods to reduce x-ray exposure frequency based on deep learning.

Cardiac coronary angiography is a major technique that assists physicians during interventional heart surgery. Under X-ray irradiation, the physician injects a contrast agent through a catheter and determines the coronary arteries' state in real time. However, to obtain a more accurate state of the coronary arteries, physicians need to increase the frequency and intensity of X-ray exposure, which will inevitably increase the potential for harm to both the patient and the surgeon. In the work reported here, the authors use advanced deep learning algorithms to find a method of frame interpolation for coronary angiography videos that reduces the frequency of X-ray exposure by reducing the frame rate of the coronary angiography video, thereby reducing X-ray-induced damage to physicians. The authors established a new coronary angiography image group dataset containing 95,039 groups of images extracted from 31 videos. Each group includes three consecutive images, which are used to train the video interpolation network model and applied six popular frame interpolation methods to the dataset to confirm that the video frame interpolation technology can reduce the video frame rate and reduce exposure of physicians to X-rays.

ST-segment depression in leads I and aVL: Artifactual or pathophysiological findings?

2021-06-16
In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2021.0013, Sharen Lee, Gary Tse, Xin Wang, Adrian Baranchuk and Tong Liu from Laboratory of Cardiovascular Physiology, Hong Kong, China, Second Hospital of Tianjin Medical University, Tianjin, China and Queen's University, Kingston, Ontario, Canada consider ST-segment depression in leads I and aVL. The 12-lead electrocardiogram (ECG) is a routinely performed test but is susceptible to misinterpretation even by experienced physicians. The authors report a case of a 72-year-old lady with no prior cardiac history presenting with atypical chest pain. Her initial electrocardiogram shows an initial ST depression followed by positive deflections leads I and aVL. ...

Pursuing safer, cheaper pharmaceuticals via electromagnetic control at the atomic level

2021-06-16
Commonplace pharmaceuticals, such as ibuprofen, can carry with them an inherent flaw in their atomic structure, which pairs the active, beneficial ingredient with a potentially ineffective -- or even toxic -- counterpart. New research could hold the key to more easily isolating the good while removing the unwanted. Dr. Shoufeng Lan, assistant professor in the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M University, is leading a team investigating the use of electromagnetic control over the synthesis of chiral compounds at an atomic level -- a process that could lead to a plethora of practical ...

Lies to hide doping in professional sport

Lies to hide doping in professional sport
2021-06-16
How do top athletes talk about doping when they themselves are using performance-enhancing drugs? Or do they just avoid the issue? A new study by the University of Göttingen reveals that any decision to use drugs almost inevitably means the decision to engage in deceptive communication such as lying or omitting information. Those using drugs, for example, regularly describe anti-doping policies as being more intense than ever or overly restrictive, play down the extent of the doping problem, or portray themselves as victims. The results were published in the European Journal for Sport and Society. Dr Marcel Reinold, Head of Sport and Health Sociology at the Institute of Sport and Exercise Sciences at Göttingen University, analysed autobiographies of professional ...

Study: Complexity holds steady as writing systems evolve

2021-06-16
A new paper in the journal Cognition examines the visual complexity of written language and how that complexity has evolved. Using computational techniques to analyze more than 47,000 different characters from 133 living and extinct scripts, co-authors Helena Miton of the Santa Fe Institute and Oliver Morin of the Max Planck Institute for the Science of Human History, addressed several questions around why and how the characters of different writing systems vary in how complex they appear. "When we started this project, we wanted to test whether you find a general simplification of characters over time," Miton says. "Do scripts simplify their ...

Immune system dysfunction can modify the association between cannabis use and psychosis

Immune system dysfunction can modify the association between cannabis use and psychosis
2021-06-16
The presence of pro-inflammatory cytokines in the blood can boost the effects of daily cannabis use and heighten the risk of developing psychosis in adulthood. Similar results have been observed, also in the presence of cytokines, when cannabis is used during adolescence. Psychotic disorders have symptoms such as delirium, loss of a sense of reality, hallucinations, hearing voices, and cognitive and social impairments. A study by researchers at the University of São Paulo's Ribeirão Preto Medical School (FMRP-USP) in Brazil, reported in an article in ...

RUDN University biologist tested the resistance of bioplastics to aggressive environment

RUDN University biologist tested the resistance of bioplastics to aggressive environment
2021-06-16
RUDN University biologist studied the aggressive impact of environmental factors (water, salts, and ozone) on ultrathin nanofibers of biopolymers. The results will help choosing suitable bioplastic depending on the use; for example, for medical implants, biodegradable packaging or filters for water cleaning. The results are published in the journal Polymers. Bioplastics are an alternative to ordinary plastics. They are obtained from waste of plant and food industry. The safe composition allows using them as filters for gases and liquids, as "sponges" for cleaning reservoirs and medical implants. Depending on the field ...

Omega-3s may hold key to unlocking blood-brain barrier

2021-06-16
NEW YORK, NY (June 16, 2021)--Spectacular images of a molecule that shuttles omega-3 fatty acids into the brain may open a doorway for delivering neurological therapeutics to the brain. "We've managed to obtain a three-dimensional structure of the transporter protein that provides a gateway for omega-3s to enter the brain. In this structure, we can see how omega-3s bind to the transporter. This information may allow for the design of drugs that mimic omega-3s to hijack this system and get into the brain," says first author Rosemary J. Cater, PhD, a Simons Society Fellow in the Mancia Lab at Columbia University Vagelos College of Physicians and Surgeons. The study was published online on June 16 in the journal Nature. A major challenge in treating ...

Graphene 'camera' captures real-time electrical activity of beating heart

2021-06-16
Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image -- almost like a video camera -- of the faint electric fields generated by the rhythmic firing of the heart's muscle cells. The graphene camera represents a new type of sensor useful for studying cells and tissues that generate electrical voltages, including groups of neurons or cardiac muscle cells. To date, electrodes or chemical dyes have been used to measure electrical firing in these cells. But electrodes and dyes measure the voltage at one point only; a graphene sheet measures the voltage ...

Are zoos inadvertently complicit in wildlife trade? The case of a rare Borneo lizard

Are zoos inadvertently complicit in wildlife trade? The case of a rare Borneo lizard
2021-06-16
Should zoos display legally protected species that have been smuggled out of their range countries? A new study suggests that a pause and rethink may be needed, as it reports that accredited zoos have acquired a rare and legally protected reptile, the earless monitor lizard endemic to Borneo, without any evidence that the animals were legally exported. The earless monitor lizard occurs only on the island of Borneo and has been described as a "miniature Godzilla" and "the Holy Grail of Herpetology." Discovered by western scientists almost 150 years ago, for most of this period the species was known largely from pickled specimens in natural history collections, and wasn't recorded from ...
