Heroin vaccine blocks lethal overdose

23/02/2018

Scientists at The Scripps Research Institute (TSRI) have achieved a major milestone toward designing a safe and effective vaccine to both treat heroin addiction and block lethal overdose of the drug. Their research, published today in the journal Molecular Pharmaceutics, shows how a new anti-heroin formulation that is safe in animal models remains stable at room temperature for at least 30 days.

Love and fear are visible across the brain instead of being restricted to any brain region

20/02/2018

The brain mechanisms of basic emotions such as anger and happiness are fairly similar across people. Differences are greater in social emotions, such as gratitude and contempt.

Neurological disease in mice and humans linked to an unlikely gene

05/02/2018

Screening for mutations influencing the migration of nerve cells in mice, scientists found a gene that plays a role in the transport of proteins within nerve cells. If less of the protein is present in the developing mouse, the scientists found that its brain showed severe defects.

Research reveals atomic-level changes in ALS-linked protein

23/01/2018

For the first time, researchers have described atom-by-atom changes in a family of proteins linked to amyotrophic lateral sclerosis (ALS), a group of brain disorders known as frontotemporal dementia and degenerative diseases of muscle and bone. Their findings appear in the journal "Molecular Cell".

The fragrance of hot pumpkin pie can bring back pleasant memories of holidays past, while the scent of an antiseptic hospital room may cause a shudder. The power of odors to activate memories both pleasing and aversive exists in many animals, from humans to the humble fruit fly.

Smart people have better connected brains

28/11/2017

Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people's brains also wired differently to those of less intelligent persons? A new study published by researchers from Goethe University Frankfurt (Germany) supports this assumption.

"A 3D movie of the brain in action"

08/12/2016

Watching millions of neurons in the brain interacting with each other – for a long time this was possible only to a limited extent. The current techniques can visualize only superficial layers or the imaging they use is too slow. But now, Prof Daniel Razansky and his team have found a new method to visualize the brain activity – by using optoacoustics.

Paraplegia: moving muscles using electrical impulses

22/11/2016

It happens about 1,800 times per year: after a sporting or traffic-related accident, a person’s spinal cord is injured to where nerve tracts are severed and he/she becomes paralyzed. Researchers now want to develop software that measures the brain signals of paralyzed patients and sends out electrical impulses via a system to stimulate muscles, causing them to move again.

Multiple Sclerosis: does the colon affect the immune system?

01/12/2015

Multiple sclerosis apparently can strike anyone - regardless of age, family history, lifestyle or gender. Yet why then does it not strike everyone? Genetic and environmental factors appear not to be the only reason whether it develops or not. The countless microorganisms that colonize our intestinal tract could also be involved in this.

ECG measurements: "Our chest strap moistens itself"

01/07/2015

When measuring myocardial activity, it is important for the skin to always stay moist under the electrodes of the ECG. Only then can data be consistently transferred. Athletes have an easier time with this: they are used to sweating. This is a lot harder for older patients.

"Neuromonitoring during lesser pelvis surgery is still uncharted territory"

08/05/2015

The bowel is surrounded by a dense plexus of nervous tissue that presents problems for surgeons. On the one hand, it is difficult to distinguish from the surrounding tissue; while on the other hand, sometimes portions of it need to be removed when parts of the colon are removed. Yet injuring these nerves can result in permanent damage.

How does a physician handle a patient, who wants to die and what rights do I actually have as a patient? Legal practitioners do not automatically answer these and other questions. We talked about this subject with MD-PhD Ralf Jox from the Institute of Ethics, History and Theory of Medicine at the Ludwig Maximilians University of Munich, Germany.

Persistent vegetative state: brain stimulation with laser beams

The public only notices diseases when celebrities become patients: in the spring of 2014, Formula One driver Michael Schumacher fell into a coma for several months as the result of a head injury caused by a skiing accident. These types of accidents show how delicate the brain responds to injuries. Brain stimulation could possibly support the rehabilitation of vegetative patients.

Diagnosing Parkinson's: the skin is revealing

01/07/2014

In patients with Parkinson's, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient's death, and not during his lifetime.
