In a small study of military personnel who had suffered head trauma and had reported memory and mood problems, UCLA researchers found brain changes similar to those seen in retired football players with suspected chronic traumatic encephalopathy.
With all the talk about the disease-fighting, life-extending superpowers of the Mediterranean diet, a lot of people are trying to cram more seafood into their meals. But there is not much talk about shellfish or whether these sea creatures deserve space on your shopping list.
Tackling unsolved problems is a cornerstone of scientific research, propelled by the power and promise of new technologies. Indeed, one of the shiniest tools in the biomedical toolkit these days is the genome editing system known as CRISPR/Cas9.
A new study has found that consistently working long shifts on hospital wards can lead to a higher risk of sickness absence for Registered Nurses (RNs) and Healthcare Assistants (HCAs).
Sugar improves memory in older adults and makes them more motivated to perform difficult tasks at full capacity according to new research by the University of Warwick. Led by Ph.D. student Konstantinos Mantantzis, Prof. Elizabeth Maylor and Dr. Friederike Schlaghecken.
Obesity is a medical problem that can have wide-ranging mental and physical effects on a person. Pamela Bass knows that firsthand, but thanks to the University of Alabama at Birmingham surgeons, she has a new lifestyle and a new state of mind.
The deaths linked to the end stages of liver damage jumped by 65% with alcohol a major cause, adults age 25-34 the biggest victims and fatalities highest among whites, American Indians, and Hispanics.
A study that examines trabecular structure throughout the distal femur of extant hominoids and test for differences due to locomotor loading regime. In addition to external bone shape and cortical bone thickness and distribution, the distribution and orientation of internal trabecular bone across individuals and species has yielded important functional information on how bone adapts in response to load.
In particular, trabecular bone analysis has played a key role in studies of human and nonhuman primate locomotion and has shown that species with different locomotor repertoires display distinct trabecular architecture in various regions of the skeleton.
A new study showed that Astronauts returned from the Moon, they experienced a number of physiological effects such as sore throats and watering eyes; symptoms that soon earned the title of “lunar hay fever.” With a renewed interest in setting up a lunar base for mining purposes and as a platform for launching interplanetary missions to Mars and beyond, the Moon is back in fashion again.
Researchers describe a method based on artificial neural networks that is able to reconstruct entire nerve cells with all their elements and connections almost error-free from image stacks. This milestone in the field of automatic data analysis could bring us much closer to mapping and in the long term also understanding brains in their entirety.
The function of the brain is based on the connections between nerve cells. In order to map these connections and to create the connectome, the "wiring diagram" of a brain, neurobiologists capture images of the brain with the help of three-dimensional electron microscopy.
Prior studies that when all clinical care team members are empowered to speak-up their performance improves. With the growing importance of patient- and family-centered care, patients and their families are a crucial component of the modern care team, as they can provide unique insight and knowledge into the discussion. More than half of patients and families expressed discomfort about raising patient safety concerns to the healthcare team. The study was published in BMJ Quality and Safety.
Researchers concerned about disruptions in the body’s day/night cycle, often called its circadian rhythm, are increasingly turning from the sleep lab to mathematics to work out thorny problems in how best to handle jetlag, shift work, and weekend lifestyle patterns.
The research draws on known factors influencing circadian rhythms and sleep, such as the effect of light, caffeine, napping, and even an increasingly sophisticated understanding of the body’s circadian pacemaker, a group of about 20,000 nerve cells in the hypothalamus, a tiny region of the brain that controls a number of important metabolic processes.
