Two years after discovering a way to neutralize a rogue protein linked to Alzheimer's disease, University of Alberta Distinguished University Professor and neurologist Jack Jhamandas has found a new piece of the Alzheimer's puzzle, bringing him closer to a treatment for the disease.
COLUMBIA, Mo. - Near an old mining town in Central Europe, known for its picturesque turquoise-blue quarry water, lay Rudapithecus. For 10 million years, the fossilized ape waited in Rudabánya, Hungary, to add its story to the origins of how humans evolved.
Results of the NRG Oncology clinical trial NRG-HN002 indicated that the combination of intensity-modulated radiotherapy (IMRT) and cisplatin was able to meet acceptability criteria for progression-free survival (PFS) and swallowing-related quality of life for patients who have p16-positive, non-smoking-associated oropharyngeal cancer. These results were highlighted during the plenary session at the American Society for Radiation Oncology's (ASTRO) Annual Meeting in September 2019 and this presentation was the recipient of ASTRO and ABR Foundation's Steven A.
Results from the Quality of Life substudy of the NRG Oncology clinical trial NSABP B-39/RTOG 0413 indicate that women rated post-lumpectomy partial breast irradiation (PBI) as equivalent to whole breast irradiation (WBI) in terms of cosmetic outcomes and satisfaction from baseline to three years following radiotherapy treatment. Treating physicians from the accruing site rated PBI as inferior to WBI while physicians who performed central review of digital photos blinded to treatment arm and time-point rated cosmetic outcome from PBI equivalent to WBI.
If you are an introvert, force yourself to be an extravert. You'll be happier.
That's the suggestion of the first-ever study asking people to act like extraverts for a prolonged period. For one week, the 123 participants were asked to - in some cases - push the boundaries of their willingness to engage, by acting as extraverts. For another week, the same group was asked to act like introverts.
Parents will be pleased to know that more is not always better when it comes to play equipment for their children.
A study by researchers at The University of Queensland found children who have access to fixed play equipment like swings and slides and fewer electronic devices were more likely to meet national physical activity guidelines.
UQ School of Public Health researcher Dr Katrina Moss said it was good news for parents, who can implement the findings at home.
Scientists at Washington University School of Medicine in St. Louis appear to have solved a decades-long mystery regarding the precise biochemical pathway leading to a fatal genetic disorder in children that results in seizures, developmental regression and death, usually around age 3. Studying a mouse model with the same human illness -- called Krabbe disease -- the researchers also identified a possible therapeutic strategy.
The research is published Sept. 16 in the Proceedings of the National Academy of Sciences.
LA JOLLA, CA – For decades, chemists have tested theories for how life began on Earth. One hypothesis has caught the scientific imagination for years: RNA World. This theory proposes that prebiotic molecules joined up early on to form RNA, the molecules that carry instructions from DNA in organisms today. RNA World posits that once RNA formed on Earth, it began replicating itself and later gave rise to molecules like DNA.
OAK BROOK, Ill. - Selective mammography screening can provide potentially lifesaving early detection of breast cancer in men who are at high risk for the disease, according to a landmark study published in the journal Radiology.
Breast cancer in men is a rare but often deadly disease. The American Cancer Society projects that 2,670 new cases of invasive breast cancer will be diagnosed in men in 2019, and about 500 men will die from it.
Crispr technology has greatly facilitated gene editing. Associate Professor Thorsten Müller from Ruhr-Universität Bochum and Dr. Hassan Bukhari from Harvard Medical School discuss its pros and cons in a review article in the journal Trends in Cell Biology from 12 September 2019. They believe Crispr technology has future potential primarily if it can be rendered usable in the field of stem cell research.
Human red blood cells (RBCs) are extremely resilient and have the capacity to undergo cellular deformation as they navigate across various micro-vessels and capillaries. Over their 120-day normal lifespan, RBCs must undergo significant cyclic deformation through large elastic stretching and relaxation. Pathological deformations in RBCs are associated with various diseases such as malaria, sickle cell anemia, diabetes, myocardial infarction and various hereditary disorders.
Researchers at the University of East Anglia have discovered how nitrogen-fixing bacteria sense iron - an essential but deadly micronutrient.
Some bacteria naturally fix nitrogen from the soil into a form that plants can use. In nature, most plants get nitrogen either from soil bacteria that do this work or from plants and microbes that die and recycle their nitrogen into the soil. In agriculture, soil is enriched with synthetic nitrogen fertilizers.
TAMPA, Fla. (September 17, 2019)- A therapeutic shoe engineered to improve stroke recovery is proving successful and expected to hit the market by the end of the year. Clinical trials have been completed on the U.S. patented and licensed iStride Device, formerly the Gait Enhancing Mobile Shoe (GEMS), with results just published in the Journal of NeuroEngineering and Rehabilitation.
A lot of people worry about microplastics and plastic pollution, but not as many of us are aware of the large number of chemicals we encounter in plastic products that we use every day.
Researchers know of more than 4,000 chemicals that are currently used in plastic food packaging. But with more than 5,000 different types of plastic on the market, the number of chemicals used to make plastics is likely even larger.
We usually think of a species as being reproductively isolated - that is, not mating with other species in the wild. Occasionally, however, closely related species do interbreed. New research just published in The Auk: Ornithological Advances documents the existence of a previously undiscovered hybrid zone along the coast of northern California and southern Oregon, where two closely related bird hummingbirds, Allen's Hummingbird and Rufous Hummingbird, are blurring species boundaries.
