(Press-News.org) Niigata, Japan - An estimated 1.13 billion people worldwide have hypertension or high blood pressure, and two-thirds of these individuals are living in low- and middle-income countries. Blood pressure is the force manifested by circulating blood against the walls of the body's arteries, the major blood vessels in the body. Hypertension is when blood pressure is too high.
Blood pressure is written as two numbers. The first (systolic) number represents the pressure in blood vessels when the heart contracts or beats. The second (diastolic) number represents the pressure in the vessels when the heart rests between beats. Hypertension is diagnosed if, when it is measured on two different days, the systolic blood pressure (SBP) readings on both days is ≥140 mmHg and/or the diastolic blood pressure (DBP) readings on both days is ≥90 mmHg.
Worldwide, high blood pressure is a common and strong risk factor for the development of cardiovascular disease. As reported by previous studies in Asia and elsewhere, as the level of SBP rises, the risk of developing cardiovascular disease increases, too. Similarly, the likelihood of dying from a cardiovascular event increases as the SBP rises. However, whether these observations hold for increases in DBP is not known. Moreover, although a high blood glucose status is itself associated with a high likelihood for the development of cardiovascular disease, it is not known whether the blood glucose status plays any role in the relationship between high blood pressure and cardiovascular events.
This theory led the authors to propose a hypothesis for their study. Commenting further, Dr. Kazuya Fujihara of the Department of Internal Medicine, Faculty of Medicine, Niigata University, said "The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) BP guideline defined blood pressure >130/80 mm Hg as hypertension. This guideline showed that the normal level is less than 120/80 mm Hg and SBP 120-129 mm Hg and DBP END
Systolic blood pressure above 120 mmHg increases rate of cardiovascular disease

Machine learning for solar energy is supercomputer kryptonite
2021-06-23
Supercomputers could find themselves out of a job thanks to a suite of new machine learning models that produce rapid, accurate results using a normal laptop.
Researchers at the ARC Centre of Excellence in Exciton Science, based at RMIT University, have written a program that predicts the band gap of materials, including for solar energy applications, via freely available and easy-to-use software. Band gap is a crucial indication of how efficient a material will be when designing new solar cells.
Band gap predictions involve quantum and atomic-scale chemical calculations ...
Tuckered out: Early Antarctic explorers underfed their dogs
2021-06-23
It's one of the iconic images of early Antarctic exploration: the heroic explorer sledging across the icy wastes towed by his trusty team of canine companions.
But new research analysing a century-old dog biscuit suggests the animals in this picture were probably marching on half-empty stomachs: early British Antarctic expeditions underfed their dogs.
In a paper just published in Polar Record, researchers from Canterbury Museum, Lincoln University and University of Otago in New Zealand analysed the history and contents of Spratt's dog cakes, the chow of choice for the canine members of early Antarctic expeditions.

Had COVID-19? One vaccine dose enough; boosters for all, study says
2021-06-23
Two mRNA vaccines against COVID-19 have proven safe and effective in clinical trials, as well as in the millions of people who have been vaccinated so far. But how prior SARS-CoV-2 infection affects vaccine response, and how long that response lasts, are still uncertain. Now, a new study in ACS Nano supports increasing evidence that people who had COVID-19 need only one vaccine dose, and that boosters could be necessary for everyone in the future.
In clinical trials, the Pfizer-BioNTech and Moderna COVID-19 vaccines were about 95% effective in protecting against symptomatic infections. Both mRNA vaccines trigger the immune system to produce antibodies against the SARS-CoV-2 spike protein receptor binding domain (RBD), and two doses are necessary to provide immunity in people ...
Combining three techniques boosts brain-imaging precision
2021-06-23
CHAMPAIGN, Ill. -- Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping.
The new "trimodal" approach combines functional MRI, electroencephalography and a third technique, called EROS, that tracks the activity of neurons near the surface of the brain using near-infrared light.
"We know that fMRI is very good at telling us where in the brain things are happening, but the signal is quite slow," said postdoctoral researcher Matthew Moore, the first ...
Mapping methane sources in Paris
2021-06-23
A potent greenhouse gas, methane is released by many sources, both human and natural. Large cities emit significant amounts of methane, but in many cases the exact emission sources are unknown. Now, researchers reporting in ACS' Environmental Science & Technology have conducted mobile measurements of methane and its sources throughout Paris. Their findings suggest that the natural gas distribution network, the sewage system and furnaces of buildings are ideal targets for methane reduction efforts.
In cities, major sources of atmospheric methane include heating systems, landfills, wastewater ...
Mining precious rare-earth elements from coal fly ash with a reusable ionic liquid
2021-06-23
Rare-earth elements are in many everyday products, such as smart phones, LED lights and batteries. However, only a few locations have large enough deposits worth mining, resulting in global supply chain tensions. So, there's a push toward recycling them from non-traditional sources, such as waste from burning coal -- fly ash. Now, researchers in ACS' Environmental Science & Technology report a simple method for recovering these elements from coal fly ash using an ionic liquid.
While rare-earth elements aren't as scarce as their name implies, major reserves are either in politically ...
New UN report calls for urgent help for world's oceans
2021-06-23
A new United Nations report calls for an urgent change in the way the world's oceans are managed.
The report from the International Resource Panel, hosted by the UN Environment Programme, raises concerns that if changes are not made quickly, the consequences will be dire.
The Governing Coastal Resources Report was launched today at an event addressed by Ambassador Peter Thomson, UN Secretary-General's Special Envoy for the Ocean. It outlines the effect land-based human activities have on the marine environment.
Put into context - 80 per cent of marine and coastal pollution originates on land, but there are very few, if any, truly effective governance mechanisms that manage land-ocean ...
Mind the gap: Scientists use stellar mass to link exoplanets to planet-forming disks
2021-06-23
Using data for more than 500 young stars observed with the Atacama Large Millimeter/Submillimeter Array (ALMA), scientists have uncovered a direct link between protoplanetary disk structures--the planet-forming disks that surround stars--and planet demographics. The survey proves that higher mass stars are more likely to be surrounded by disks with "gaps" in them and that these gaps directly correlate to the high occurrence of observed giant exoplanets around such stars. These results provide scientists with a window back through time, allowing them to predict what exoplanetary ...
People overestimate Black Americans' chances of economic success
2021-06-23
COLUMBUS, Ohio - Americans consistently believe that poor African Americans are more likely to move up the economic ladder than they actually are, a new study shows.
People also overestimate how likely poor white people are to get ahead economically, but to a much lesser extent than they do for Black people.
"It's no surprise that most people in our society believe in the American Dream of working hard and succeeding economically," said Jesse Walker, co-author of the study and assistant professor of marketing at The Ohio State University's Fisher College of Business.
"But many people don't know how much harder it is for African Americans to achieve ...
Subconscious changes in movement may predict Alzheimer's disease
2021-06-23
As people go about their daily activities, complex fluctuations in their movement occur without conscious thought. These fluctuations -- known as fractal motor activity regulation (FMAR) -- and their changes are not readily detectable to the naked eye, but FMAR patterns can be recorded using a wristwatch-like device known as an actigraph. A new study, led by investigators at Brigham and Women's Hospital, the Massachusetts General Hospital (MGH) and Washington University at St. Louis, analyzed FMAR patterns in cognitively healthy adults who were also tested for established biomarkers of preclinical Alzheimer's disease (AD) pathology. The team found that FMAR was associated with preclinical AD pathology in women, suggesting that FMAR may be a new biomarker for AD before cognitive symptoms ...
