Diagnosed with type 2 diabetes, high cholesterol and borderline high blood pressure, Dana Hayes pursued bariatric surgery in hopes of living a healthier life.
"I struggled with weight my whole life, but this was a place I'd never been before," says Hayes, 30, a hairdresser and mother of four. "Diabetes was the final straw."
She waited five months for surgery after her first clinic appointment.
New York, NY--July 30, 2018--Lithium metal batteries hold tremendous promise for next-generation energy storage because the lithium metal negative electrode has 10 times more theoretical specific capacity than the graphite electrode used in commercial Li-ion batteries. It also has the most negative electrode potential among materials for lithium batteries, making it a perfect negative electrode. However, lithium is one of the most difficult materials to manipulate, due to its internal dendrite growth mechanism.
Scientists at the University of Illinois at Urbana-Champaign have developed an algorithm that could provide meaningful answers to condensed matter physicists in their searches for novel and emergent properties in materials. The algorithm, invented by physics professor Bryan Clark and his graduate student Eli Chertkov, inverts the typical mathematical process condensed matter physicists use to search for interesting physics.
The Eastern Pacific Ocean's Tropical Depression 8E formed on July 26 and strengthened into a tropical storm by 5 a.m. EDT on July 27. At that time the storm was renamed Gilma. NASA's Terra satellite provided forecasters with an early look at the eighth depression as it was developing.
The Eastern Pacific Ocean's Tropical Depression 9E formed on July 26 and by July 27 the depression had dissipated over 1,200 miles from Hilo, Hawaii. NASA's Terra satellite captured a look at the storm at its peak.
Carbon materials (CMs) exhibit great application potentials in diverse fields due to their high electric conductivity, good chemical stability, and unique microstructure. Traditionally, CMs were prepared by the carbonization of low-vapor-pressure natural products or synthetic polymers. But they suffer from some distinct disadvantages, such as difficulty in tailoring the microstructures and chemical compositions of the obtained products, or complicated and slow polymerization processes.
Patients with spinal fractures caused by tumors or osteoporosis usually undergo a procedure called kyphoplasty, where the fracture is filled with surgical cement. While kyphoplasty can stabilize the bone, cancer patients are still often left with spinal column tumors that are very hard to reach with conventional chemotherapy, which has to cross the blood-brain barrier when delivered intravenously.
The Global Precipitation Measurement mission or GPM core satellite provided a rainfall and cloud analysis on powerful Typhoon Jongdari as it moves toward Japan. Jongdari follows another powerful typhoon that made landfall in Japan earlier this year.
Many foods produced on an industrial scale include raw ingredients mixed together in enormous stainless steel machines that can be difficult to clean. With repeated use, equipment surfaces get minute scratches and grooves, providing bacteria and biofilms the perfect place to hide. While surface scratches may appear small to the naked eye, they are like a canyon to bacteria, which are only a few micrometers in size. Surface-trapped food residue and bacteria then increase the risk of contamination from microorganisms such as Salmonella, Listeria and E. coli.
The financial costs of flooding in Canada's maritime region could spike by 300 per cent by the end of the century if steps are not taken to address the impacts of climate change.
A study done by researchers at the University of Waterloo looked at the Halifax, Nova Scotia area, a region hard hit by recent riverine flooding. The team, made up economists, geographers and political scientists, merged data on flood probability, climate change and financial payout information from the insurance/re-insurance market and used the information to develop a forecast.
Norovirus is the most common cause of gastroenteritis worldwide; it causes tens hundreds of thousands of deaths each year and is particularly risky for children under 3 years old. If someone gets norovirus in a setting like a hospital, it's critically important to find a way to protect others from getting infected.
Water is vital for life.
But as our climate changes, the availability of water is also changing, leaving animals with limited or unreliable supplies of this critical resource.
DURHAM, N.C. -- Engineers at Duke University have developed a way to manipulate, split and mix droplets of biological fluids by having them surf on acoustic waves in oil. The technology could form the basis of a small-scale, programmable, rewritable biomedical chip that is completely reusable for disparate purposes from on-site diagnostics to laboratory-based research.
The study appears on July 26 in the journal Nature Communications.
Detectors that are presently used for mammograms and for dose measurements in radiotherapy are often rigid, causing errors in screening, or dose delivery to surrounding healthy tissue. This has raised concerns of additional tissue damage or the growth of secondary tumours. While flexible x-ray films such as those used in dentistry or chest x-rays bypass this issue, they are not able to achieve real-time imaging. Similarly, high-speed monitoring of people and vehicles over large geographical areas, which is important in border security, is impeded with the current technology.
A catheter based procedure to close a type of 'hole in the heart' followed by antiplatelet drugs (e.g. aspirin) should be recommended for patients under 60 years old, who have also had a stroke, say a panel of experts in The BMJ today.
The procedure involves slowly moving a catheter (a long, thin, flexible tube) into the heart to close the hole. Most guidelines currently advise against the closure procedure and instead recommend taking life long anti-clotting drugs to prevent further strokes.
