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.
Each year during the holiday season, soup kitchens and charities alike are flooded with offers to volunteer. But is a donation of your time most beneficial to the charity, or would a financial contribution provide more value? Researchers from Portland State University and Texas A&M University wondered what drives volunteering -- especially when a monetary donation would have more impact. Their study, "Why Do People Volunteer? An Experimental Analysis of Preferences for Time Donations," was published... Читать дальше...
Research presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting draws a strong link between severe obstructive sleep apnea (OSA) and impaired coronary flow reserve, which is an early sign of the heart disease atherosclerosis. Using 13N-ammonia positron emission tomography/computed tomography (PET/CT), researchers were able to noninvasively evaluate coronary microvascular function in OSA patients and use their findings to predict cardiovascular disease risk.
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).
Young women who undergo radiation therapy to treat a pediatric brain tumor are more likely to suffer from long-term cognitive impairment than male survivors, according to a study by Georgia State University researchers.
A newly identified hunger pathway in the brain can quickly modify food intake in the presence of food, according to a study of mice published in JNeurosci. This pathway could be a future target for the treatment of eating disorders.
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.
A study by scientists at Boston Children's Hospital and Brigham and Women's Hospital, published today in Nature Medicine, makes a strong case that the national epidemic of food allergy is caused by the absence of certain beneficial bacteria in the human gut. 'The loss of these bacteria acts as a switch that makes children susceptible to food allergy,' says Talal Chatila, MD, director of the Food Allergy Program at Boston Children's and a senior author on the paper.
Researchers at the Stanford University School of Medicine and their collaborators have created one of the first maps to reveal gene activity and connectivity as the heart shuts down.
Researchers led by an electrical engineer from the University of Houston have reported solving a lingering question about how a two-dimensional crystal composed of cesium, lead and bromine emitted a strong green light, opening the door to designing better light-emitting and diagnostic devices.
Using complex statistical methods and fast measurement techniques, researchers found how the brain network comes up with the right word and enables us to say it.
By tracking water flow through different environments in California, UC Berkeley researchers have discovered a secret to the surprising resilence of Mediterranean plant communities during drought years. These plants do well during droughts because they are adapted to living with limited underground water storage even in very wet years. Rock moisture, or lack of it, is the key, and may help predict the fate of other California plant communities in the face of climate change.
(Baylor College of Medicine) Baylor College of Medicine has issued a response to the measles outbreak, calling on the public to communicate with elected officials, family and friends about the importance of vaccinations and evidence-based vaccine policies that promote public health.
A new article published today in the journal Frontiers in Cellular and Infection Microbiology shows that research built around human-mimetic tools are more likely to succeed in the search for effective treatments for and prevention of flavivirus infection as compared to research using monkeys or other animals as laboratory models.
According to a first-of-its-kind study, cities with a higher incidence of a certain kind of racist tweets reported more actual hate crimes related to race, ethnicity, and national origin. Using machine learning, the researchers analyzed the location and linguistic features of 532 million tweets published between 2011 and 2016. The team found that cities with more targeted racist tweets, espousing discriminatory views, also had more real-life hate crimes.
A collaborative team of Harvard researchers pinpointed one specific group of bacteria, called Veillonella, that they found was enriched in the gut microbiome of Boston Marathon runners after after completing the 26.2 race and in an independent group of 87 elite and Olympic athletes after competitions. Veillonella bacteria isolated from marathon athletes and given to mice increased the animals' performances in laboratory treadmill tests by 13% compared to control bacteria.
In July's SLAS Discovery feature article, '3D Cell-Based Assays for Drug Screens: Challenges in Imaging, Image Analysis, and High-Content Analysis,' Tijmen H. Booij, Ph.D., Screening Specialist for NEXUS Personalized Health Technologies (Switzerland), discusses the switch from using 2D to 3D cell cultures in drug discovery to more accurately mimic human physiological conditions and improve the success rates of drugs in the early stages of preclinical drug discovery.
SHERLOCK technology is a new CRISPR-based platform that is rapid and portable and enables detection and quantitation of plant genes to support a variety of agricultural applications. Additional advantages, including the ability to process crude plant extracts with minimal nucleic acid sample preparation required are described in a research article published in The CRISPR Journal, a new peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
A new study raises the possibility that close-range blast exposure among veterans with a genetically higher risk for Alzheimer's disease (AD), may make them more susceptible to degradation of their white matter, the part of the brain made of fiber connections called axons that connect nerve cells.
For the first time, researchers have shown a causal link between print news media coverage of US gun control policy in the wake of mass shooting events and increases in firearm acquisition, particularly in states with the least restrictive gun laws.
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.
Researchers are developing better, faster ways of providing human guidance to autonomous robots.
During the recent AIA Conference in Las Vegas, ArchDaily had the opportunity to interview Tom Kundig, Principal at Olson Kundig who has been designing and building for the firm for the last 30 years.
(University of Gothenburg) A warm smile and a caring hand on the shoulder are not enough to overcome the language barriers that can arise between parents and healthcare professionals in neonatal care in Sweden when the parents have not mastered the Swedish language. A new thesis raises the questions of when and how to get the assistance of an interpreter.
(Future Science Group) Future Science Group (FSG) is pleased to announce it has expanded its partnership with ScienceOpen, with two new collections featuring the journals BioTechniques and Future Drug Discovery.
