More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
Each injury means a little more as individuals age -- more impact and more healing time.
A group of scientists and dermatologists are now looking at the role sweat glands play in how aging skin recovers from wounds. It's a step to better learn about aging skin, in order to better treat -- and slow -- the process.
Their research, recently published in Aging Cell, compared 18 elderly subjects' skin to 18 young adults' skin, to see how each group healed from skin lesions. The lesions were smaller than the diameter of a pencil eraser, performed under local anesthesia.
Eight days. That's how long it takes for skin cells to reprogram into red blood cells. Researchers at Lund University in Sweden, together with colleagues at Center of Regenerative Medicine in Barcelona, have successfully identified the four genetic keys that unlock the genetic code of skin cells and reprogram them to start producing red blood cells instead.
"We have performed this experiment on mice, and the preliminary results indicate that it is also possible to reprogram skin cells from humans into red blood cells. One possible application for this technique is to make personalised red blood cells for blood transfusions, but this is still far from becoming a clinical reality", says Johan Flygare, manager of the research group and in charge of the study.
June 2, 2016 - Visual blurring -- like that produced by bifocals or multifocal lenses -- may cause errors in foot position when walking. And that could contribute to the risk of tripping and falling in older adults, suggests a study in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
It has been established that not all cancer cells are equally aggressive -- most can be neutralised with radiation and chemotherapy. Researchers at Lund University in Sweden have now discovered that some cancer cells can accumulate fat droplets, which appear to make them more aggressive and increase their ability to spread.
The interior of a cancer tumour is a hostile environment with oxygen deficiency, low pH levels and lack of nutrients. The cells that survive in this environment are called "stressed cells" and are considered to be more aggressive.
Men still outperform women in undergraduate introductory biology tests and humanities scholars are scrambling to blame the tests. And the wealth of families. Anything except the fact that on different tests in different classes at different times, test performance will vary and is not a problem that can be fixed by creating a test where women, or poor women, will be guaranteed to do better.
How is performance different? When it comes to memorization tests, facts, both genders are equal, but when tests include cognitively challenging questions that require elevated critical thinking, females and lower socioeconomic students score lower than their male or high-status peers. Publishing that result without hedging is a sure way to get through out of a university.
Infant formula was the great liberator for working moms who wanted to have careers but in the last decade there has been a backlash against it, often adopting the veil of scientific legitimacy.
Simon Fraser University researchers hope that a brain vital-sign test becomes as routine during a doctor's check-up as taking a blood pressure or heart rate measurement.
SFU researchers, led by professor Ryan D'Arcy with partners from the Mayo Clinic, Sheba Medical Centre in Israel and local high-tech company HealthTech Connex Inc., are developing a more accessible means to monitor brain health.
In a recent article published in the journal Frontiers in Neuroscience, the team introduces the world's first advancement in physiology-based brain vital signs. Their discovery makes it possible to translate complex brainwaves into objective, practical and deployable brain vital signs, using longstanding brainwave technologies that have existed for nearly a century.
ATLANTA - June 2, 2016 -There were more than 15.5 million Americans with a history of cancer as of January 1, 2016, a number that is projected to reach more than 20 million by 2026. That's according to Cancer Treatment and Survivorship Statistics, 2016, published in CA: A Cancer Journal for Clinicians, a peer-reviewed journal of the American Cancer Society, and its companion publication for consumers, Cancer Treatment & Survivorship Facts & Figures, 2016-2017. The report was released ahead of National Cancer Survivors Day, Sunday June 5, 2016.
The lungs contain a thin layer of fluid known as the airway surface liquid (ASL), which helps protect against pathogens. The appropriate ASL volume, pH, and ionic composition are required for optimal airway defense. Cystic fibrosis (CF) is caused by expression of a dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR), which acidifies the ASL and renders CF patients more susceptible to lung infections. In this issue of JCI Insight, Joseph Zabner and colleagues at the University of Iowa Carver College of Medicine examined the effect of tromethamine, a drug that is currently approved to treat metabolic acidosis, on ASL pH and bacterial killing activity. They demonstrated that inhalation of aerosolized tromethamine raised ASL pH in both pigs and CF patients.
In the first year that two Florida laws aimed at curbing opioid prescriptions were in effect, the state's top opioid prescribers wrote significantly fewer prescriptions of this type of pain medication, a new analysis led by researchers at the Johns Hopkins Bloomberg School of Public Health finds.
Underwater divers recently discovered paved floors, courtyards and colonnades, evidence of a long-forgotten civilization that must have perished when tidal waves hit the shores of the Greek holiday island Zakynthos.
The bizarre discovery, found close to Alikanas Bay, was carefully examined in situ by the Ephorate of Underwater Antiquities of Greece. After the preliminary mineralogical and chemical analyses, a research team was mobilized to study the ancient underwater remains - only to declare them a naturally occurring phenomenon created by a natural geological phenomenon that took place in the Pliocene era, up to five million years ago.Credit: UEA
Normal rules of economic behavior would dictate that free upgrades to a particular product would move it out the door in record numbers. Somewhat counterintuitively, new research from Professor Wen Mao reveals that a token upgrade fee, even no more than a penny, is often more attractive to consumers than a freebie.
