Smoking increases both men's and women's risk of a major heart attack at all ages, but women smokers have a significantly higher increased risk compared to men, especially women under 50 years old, according to a study in the Journal of the American College of Cardiology. Despite the increased risk, smokers can reduce their risk to that of a never smoker in as little as a month after quitting.
Washington, DC - June 24, 2019 - A team of investigators has developed a cancer vaccine technology using live, attenuated pathogens as vectors. A feature of the vaccine causes these bacteria to self-destruct once they've done their job, making it safe for use in humans. The research is published in Infection and Immunity, a journal of the American Society for Microbiology.
Following a stroke, antibodies that inhibit the signaling molecule Nogo-A can help repair blood vessels in the affected brain regions. This also promotes the regaining of motor functions, researchers at the University of Zurich have shown in a mouse model. The study opens up new avenues for treatment.
PHILADELPHIA (June 24, 2019) - New research from the Monell Center analyzed nearly 400,000 food reviews posted by Amazon customers to gain real-world insight into the food choices that people make. The findings reveal that many people find the foods in today's marketplace to be too sweet.
Told to optimize for speed while racing down a track in a computer game, a car pushes the pedal to the metal ... and proceeds to spin in a tight little circle. Nothing in the instructions told the car to drive straight, and so it improvised.
This example - funny in a computer game but not so much in life - is among those that motivated Stanford University researchers to build a better way to set goals for autonomous systems.
Researchers drew attention three years ago when they reported that a two-dimensional perovskite - a material with a specific crystal structure - composed of cesium, lead and bromine emitted a strong green light. Crystals that produce light on the green spectrum are desirable because green light, while valuable in itself, can also be relatively easily converted to other forms that emit blue or red light, making it especially important for optical applications ranging from light-emitting devices to sensitive diagnostic tools.
New prostate cancer research shows that adding an interim scan during therapy can help guide a patient's treatment. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging of patients with metastatic castration-resistant prostate cancer after two cycles of lutetium-177 (177Lu)-PSMA radioligand therapy has shown a significant predictive value for patient survival. The research was presented at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI).
Graphene is the thinnest and strongest material known to humans. It's also flexible, transparent and conducts heat and electricity 10 times better than copper, making it ideal for anything from flexible nanoelectronics to better fuel cells.
The new approach by researchers from RMIT University (Australia) and the National Institute of Technology, Warangal (India), uses Eucalyptus bark extract and is cheaper and more sustainable than current synthesis methods.
Immunotherapies have revolutionized the care of many cancers, teaching the body's own immune cells to recognize and attack tumor cells. Leading the way are drugs known as checkpoint inhibitors, which block a kind of "white flag" that tumors wave as a peace signal to T cells that would very much like to kill them. Really, this white flag is a protein called PD-L1 -- many tumors coat themselves in it. When PD-L1 on the surface of a cancer cell sees its partner, PD1, on T cells, these T cells are tricked into letting the cancer cell live.
New Haven, Conn. -- Use of 3-D mammography, an advanced form of breast cancer screening, has risen rapidly in recent years, according to Yale researchers in a new study. But adoption of the technology varies widely, reflecting emerging disparities in care, they said.
The study was published in the journal JAMA Internal Medicine.
Bottom Line: Having a family member who was previously dispensed prescription opioids was associated with higher odds of overdose for individuals who themselves didn't have an opioid prescription in this analysis of insurance company data. The study included 2,303 people with the earliest date of an opioid overdose in a family and 9,212 others in the insurance database for comparison. Researchers report the increased risk of opioid overdose for an individual if a family member was prescribed an opioid applied to all age groups and increased with greater quantities of opioids prescribed.
HANOVER, N.H. - June 24, 2019 -Using smartphones, fitness bracelets and a custom app, researchers have created a mobile-sensing system that judges employee performance.
The system works by monitoring the physical, emotional and behavioral well-being of workers to classify high and low performers.
The project gives valuable new insights on how genetic adjustments through evolution have rendered the ruminants one of the most successful groups of animals on the planet. The results have recently been published in three articles in the acknowledged scientific journal Science.
Approx. 20 million years ago, ruminants began to outmatch all other groups of large herbivores. Today ruminants count more than 200 species from all ecosystems and in all sizes, ranging from 2 to 1500 kg.
Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single application containing two active components.
One of the most challenging issues for game players looks to be resolved soon with the introduction of a zero-latency gaming environment. A KAIST team developed a technology that helps game players maintain zero-latency performance. The new technology transforms the shapes of game design according to the amount of latency.
