In a pilot study of 14 older adults with mild cognitive problems suggestive of early Alzheimer's disease, Johns Hopkins Medicine researchers report that a high-fat, low-carbohydrate diet may improve brain function and memory.
Using cutting-edge electron microscopy, researchers from Aarhus University have determined the first structures of a lipid-flippase. The discoveries provide a better understanding of the basics of how cells work and stay healthy, and can eventually increase our knowledge of neurodegenerative diseases such as Alzheimer's.
San Diego, CA - June 27, 2019 - Meal delivery drivers bringing food to homebound seniors can be an effective early-warning system for health and safety problems, according to a new study published in the Journal of the American Geriatrics Society by researchers at the West Health Institute, Brown University and Meals on Wheels America.
In a recent study with 3 to 7-year-old children provided an example of how children's daily living environment and motor skills are closely related in the Finnish context. The main finding revealed that residential density is related to children's motor skills, engagement in outdoor play and organised sports. It was found that Finnish children living in the countryside spent more time outdoors and had better motor skills than their age peers in the metropolitan area. On the other hand, children living in the metropolitan area participated the most in organised sports.
Water is a vital resource for people and the environment. One of the most important sources is groundwater which is renewed from precipitation or surface water. Population growth as well as agriculture and industry strongly influence the quantity and quality of groundwater. To be able to investigate groundwater resources more easily, cost-effectively and comprehensively than in the past, researchers at Karlsruhe Institute of Technology (KIT) have developed a new method with Australian colleagues which they are now unveiling in the Reviews of Geophysics journal.
Insights into how a gene that increases the risk of Alzheimer's disease disrupts brain cells have been revealed by scientists.
Brain tissue from people with Alzheimer's showed that a protein called clusterin builds up in vital parts of neurons that connect cells and may damage these links.
Scientists say the findings shed light on the causes of the disease and will help to accelerate the search for a treatment.
Osaka, Japan - The early development of embryos is not well understood. One necessary stage is the formation of the blastocyst, a collection of cells present by about 4 days after fertilization of the egg, before implantation in the uterus. From that tiny collection of cells, all the different cells in the body must be created. Accordingly, there need to be mechanisms in the blastocyst to ensure normal gene expression and cell differentiation; those regulatory mechanisms are still largely unknown.
Infants of women with a short-term education are more likely to die within the first year of life. In more than half of cases, the cause of death is premature childbirth and low foetal weight. This is shown by research from Aarhus University and Aarhus University Hospital.
Prof. HU Junjie from the Institute of Biophysics of the Chinese Academy of Sciences and his collaborators reported that the endoplasmic reticulum (ER) fusogen atlastin (ATL) was involved in regulating cargo mobility and COPII formation in the ER. Their finding, published in PNAS on June 25, provides important insight into the physiological role of the tubular ER network.
Professor Atsushi Sato of the University of Toyama and Ai Matsuo, a researcher at The Open University of Japan, in cooperation with Professor Michiteru Kitazaki of Toyohashi University of Technology have found that social contingency modulates one's perceptual representation of the environment.
(Boston)--Increasing the levels of the anti-aging protein hormone Klotho improves the neurological deficits and prolongs life span in an experimental model with Amyotrophic Lateral Sclerosis (ALS). In addition, brain immune cells called microglia play an important role in protecting the brain against inflammation and, likely, motor neuron loss in this model.
Many work processes would be almost unthinkable today without robots. But robots operating in manufacturing facilities have often posed risks to workers because they are not responsive enough to their surroundings. To make it easier for people and robots to work in close proximity in the future, Prof. Matthias Althoff of the Technical University of Munich (TUM) has developed a new system: IMPROV.
Early disease stages of MS are primarily characterised by immune cell infiltration of the CNS. This causes inflammation that damages the so-called myelin sheaths. Myelin sheaths are electrically insulating structures established by specialised glial cells of the CNS, referred to as 'oligodendrocytes'. These structures protect, nourish and stabilise axons, which transmit electrical signals between neurons.
Experts led by the Institute for Sustainable Food at the University of Sheffield reveal how plants provide a steady flow of air to every cell
Study shows humans have bred wheat plants to have fewer pores on their leaves and use less water
Findings pave the way to develop more drought-resistant crops
Scientists have discovered how plants create networks of air channels - the lungs of the leaf - to transport carbon dioxide (CO2) to their cells.
In the past few years, thrill-seekers from Hollywood, Silicon Valley and beyond have been travelling to South America to take part in so-called Ayahuasca retreats. Their goal: to partake in a brewed concoction made from a vine plant Banisteriopsis caapi, traditionally used by indigenous people for sacred religious ceremonies. Drinkers of Ayahuasca experience short-term hallucinogenic episodes many describe as life-changing.
