Rsearchers assessed moderate to severe traumatic brain injury (TBI) for frontal behavioral syndromes and cognitive function. Their finding suggest that adding the Frontal Systems Behavior Scale to neuropsychological assessment may yield useful information about the behavioral sequelae of TBI.
Were dinosaurs really fast, aggressive hunters like the ones depicted in the movie 'Jurassic World'? Or did they have lower metabolic rates that made them move more like today's alligators and crocodiles? New research indicates that some dinosaurs, at least, had the capacity to elevate their body temperature using heat sources in the environment, such as the sun.
The hunt for a vaccine against malaria in pregnant women has provided an unexpected side benefit for researchers, namely what appears to be an effective weapon against cancer. The scientists behind the vaccine aim for tests on humans within four years.
Researchers have demonstrated a noninvasive light-based imaging technology enabling study of the living brain and providing a new tool to study how diseases like dementia, Alzheimer's, and brain tumors change brain tissue over time.
A study describes how the changing viral swarm in an HIV infected person can drive the generation of antibodies able to neutralize HIV strains from across the world. This work has important implications for the design of a protective HIV vaccine, say the researchers.
New research has challenged claims that sitting for long periods increases the risk of an early death even if you are otherwise physically active. The study followed more than 5000 participants for 16 years (making it one of the longest follow-up studies in this area of research) and found that sitting, either at home or at work, is not associated with an increased risk of dying.
In Alzheimer’s disease proteins clump together to long fibrils causing the death of nerve cells. Small heat shock proteins can counteract this effect. Scientists, therefore, hope to deploy them as agents in the treatment of neurodegenerative diseases. Using the example of a small heat shock protein, researchers have now uncovered how the protein interacts with other proteins.
'Multi-step' programs in diabetes screening lead to more people responding to screening invitations and the number of those needing a final test for a definite diagnosis being reduced, suggest authors of a new report.
Researchers have revealed how obesity surgery recovers opioid neurotransmission in the brain. Obesity surgery provides an effective means for rapid weight loss, and the research also shows that obesity surgery also normalizes brain circuits triggering pleasurable sensations when eating.
In a study involving 2,400 men who have sex with men who were also enrolled in the Multicenter AIDS Cohort Study, researchers report that men with HIV who were treated effectively with HIV therapy — defined as no detectable HIV virus in the blood — were the least likely (80 percent less likely) to get infected with HBV over a median follow-up of approximately 9.5 years
Girls who suffer a concussive bump on the head in childhood could be at increased risk for abusing alcohol as adults, a new study suggests. The research in mice found that females with a mild closed-head brain injury were more likely to misuse alcohol later in life and associate drinking with reward and pleasure. This effect was not seen in males.
The average life span of smokers is more than 10 years shorter than that of non-smoker, and it is said that smoking is a factor which accelerates aging. However, the details of the mechanism which accelerates aging due to smoking has not, to date, been clear.
A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now researchers have found the first actual 'sensor mechanism' that allows a living cell detect an electric field.
Every second trillions of data bits are accumulated and stored. All these data bits make no sense if you don't know how to sort them. Now researchers present a tool that helps researchers sort data and retrieve meaningful knowledge from the data jungle.
