Predictive value of blood pressure, heart rate, and blood pressure/heart rate ratio in a Chinese subpopulation with vasovagal syncope

2021-01-22
(Press-News.org) In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2019.1266, Zhuzhi Wen, Jingying Hou, Zun Mai, Huifen Huang, Yangxin Chen, Dengfeng Geng and Jingfeng Wang from Sun Yat-sen University, Guangzhou, China and Guandong Province Key Laboratory of Arrhythmia and Electrophysiology, Guangzhou, China consider predictive value of blood pressure, heart rate, and blood pressure/heart rate ratio in a Chinese subpopulation with vasovagal syncope.

Blood pressure, heart rate and ratios of blood pressure to heart rate in the titled position during the simplistic tilt test had predictive value with regard to the presence, pattern, and stage of syncope during the head-up tilt test.

Ratios of blood pressure to heart rate derived from ambulatory blood pressure monitoring (ABPM) may be better predictors of the presence and pattern of vasovagal syncope (VVS), while ABPM-derived blood pressure should be used to predict the time when syncope will happen.

The authors found significant correlations in blood pressure to heart rate ratios between ABPM and the simplistic tilt test, and different VVS patterns had different correlative features. Parameters from both ABPM and the simplistic tilt test may be promising alternatives to the head-up tilt test in VVS evaluation.

A method for calculating optimal parameters of liquid chrystal displays developed at RUDN University

A method for calculating optimal parameters of liquid chrystal displays developed at RUDN University
2021-01-22
A professor from RUDN University together with his colleagues from Saratov Chernyshevsky State University and D. Mendeleev University of Chemical Technology of Russia developed a method for calculating the parameters of diffraction optical elements used in LCDs. In particular, the new technology can be used to expand the angle of view while preserving high resolution and color rendition. The results of the study were published in the Journal of The Society for Information Display. Each pixel on a display corresponds to a group of three light sources: red, green, and blue. When the brightness of all three diodes is the same, white light is produced; and by changing the share of each respective ...

No more needles for diagnostic tests?

No more needles for diagnostic tests?
2021-01-22
Blood draws are no fun. They hurt. Veins can burst, or even roll -- like they're trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis. These biomarkers aren't just in blood, though. They can also be found in the dense liquid medium that surrounds our cells, but in a low abundance that makes it difficult to be detected. Until now. Engineers at the McKelvey School of Engineering at Washington University in St. Louis have developed a microneedle patch that can be applied to the skin, capture a biomarker of interest ...

A professor from RUDN University developed new liquid crystals
2021-01-22
A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels. The results of the study were published in the Journal of Molecular Liquids. Liquid crystals are an intermediate phase between a liquid and a solid body. They are ordered like regular chrystals but at the same time have a flow like liquids. It is this duality that allows them to be used in organic LEDs and LCDs. Unlike other liquid crystals, discotic ones (DLC) are capable of self-assembly into ordered structures. This makes them a promising material for industrial electronics, namely, for the production of displays. ...

Wet and wild: There's lots of water in the world's most explosive volcano

Wet and wild: Theres lots of water in the worlds most explosive volcano
2021-01-22
There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka's Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, creating a new crater and covering an area of nearly 100 square kilometers with pyroclastic flows. But Shiveluch is actually currently erupting, as it has been for over 20 years. So why would anyone risk venturing too close? Researchers from Washington University in St. Louis, including Michael Krawczynski, assistant professor of earth ...

Exercising muscle combats chronic inflammation on its own

2021-01-22
DURHAM, N.C. - Biomedical engineers at Duke University have demonstrated that human muscle has an innate ability to ward off the damaging effects of chronic inflammation when exercised. The discovery was made possible through the use of lab-grown, engineered human muscle, demonstrating the potential power of the first-of-its-kind platform in such research endeavors. The results appear online on January 22 in the journal Science Advances. "Lots of processes are taking place throughout the human body during exercise, and it is difficult to tease apart which systems and cells are doing what inside an active person," said Nenad Bursac, professor of biomedical engineering at Duke. "Our engineered muscle ...

From fins to limbs

2021-01-22
When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans and some aquatic vertebrates such as whales and dolphins. The earliest tetrapods originated from their fish ancestors in the Devonian period and are more than twice as old as the oldest dinosaur fossils. They resembled a cross between a giant salamander and a crocodile and were about 1-2 meters long, had gills, webbed feet and tail fins, and ...

UK public supports usage of tracking technology and immunity passports in global pandemic

2021-01-22
New research suggests the majority of people in the UK are willing to use privacy-encroaching tracking technology and support the introduction of 'immunity passports' to protect themselves and others in the COVID-19 pandemic. The study, published today in the journal PLOS ONE, found more than two thirds of respondents overall would accept some form of smartphone tracking app to help manage social distancing and the relaxation of a full public lockdown. However, its findings are not reflected in the number of people who have downloaded the NHS Test and Trace app, prompting calls for this issue to be addressed. Lead author Professor Stephan Lewandowsky, Chair in Cognitive Psychology at the University of Bristol, said: "Attitudes were surprisingly permissive and this ...

Climate and carbon cycle trends of the past 50 million years reconciled

Climate and carbon cycle trends of the past 50 million years reconciled
2021-01-22
Predictions of future climate change require a clear and nuanced understanding of Earth's past climate. In a study published today in Science Advances, University of Hawai'i (UH) at Mānoa oceanographers fully reconciled climate and carbon cycle trends of the past 50 million years--solving a controversy debated in the scientific literature for decades. Throughout Earth's history, global climate and the global carbon cycle have undergone significant changes, some of which challenge the current understanding of carbon cycle dynamics. Less carbon dioxide in the atmosphere cools Earth and decreases weathering of rocks and minerals on land over long time scales. Less weathering should lead to a shallower calcite compensation depth (CCD), which is the depth in the ocean where ...

Crystal structures in super slow motion

Crystal structures in super slow motion
2021-01-22
Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation. Researchers at the University of Göttingen and the Max Planck Institute (MPI) for Biophysical Chemistry in Göttingen have now managed to film, for the first time, the laser transformation of a crystal structure with nanometre resolution and in slow motion in an electron microscope. The results have been published in the journal Science. The ...

University of Cincinnati research unveils possible new combo therapy for head and neck cancer

University of Cincinnati research unveils possible new combo therapy for head and neck cancer
2021-01-22
Head and neck cancer is the sixth most common cancer worldwide, and while effective treatments exist, sadly, the cancer often returns. Researchers at the University of Cincinnati have tested a new combination therapy in animal models to see if they could find a way to make an already effective treatment even better. Since they're using a Food and Drug Administration-approved drug to do it, this could help humans sooner than later. These findings are published in the journal END ...
