Myocardial Infarction, the number one cause of Sudden Death, may be treated by Modulating the Immune Response

Reduced inflammation at the site of myocardial infarction and improved heart function demonstrated. Novel therapy to modulate immune response with apoptotic cell-derived nanovesicles.

Myocardial infarction, the number one cause of sudden death in adults and the number two cause of death in Korea, is a deadly disease with an initial mortality rate of 30%, and about 5%–10% of patients die even if they are transported to a medical center for treatment.

The number of myocardial infarction patients in Korea has been increasing steeply, from 99,647 in 2017 to 126,342 in 2021, an increase of 26.8% in five years...

Study shows that Common Supplements may Reduce Natural Hearing Loss

Researchers report that age-related hearing loss is associated with a decrease of cholesterol in the inner ear.

Experiments published August 24 in the open access journal PLOS Biology show that phytosterols supplements were able to act in place of the lost cholesterol and prevent sensory dysfunction in mice.

Sensory cells in the inner ear called outer hair cells (OHCs) amplify sounds by changing their length. As we age, these cells lose their ability to stretch in response to sound, preventing sound amplification and leading to age-related hearing loss...

Neuroscientists and psychologists have been trying for decades to better understand how humans make decisions, in the hope to devise more effective interventions to promote healthy and beneficial lifestyle choices. Two brain regions that have been linked to decision-making are the orbitofrontal cortex (OFC) and the anterior cingulate cortex (ACC).

Researchers at University of California, Berkeley (UC Berkeley), have been conducting extensive research focusing on these two areas of the brain and exploring their involvement in decision-making...

Deficiency in Certain Brain Proteins shown to Promote Compulsive Behavior

Our behavior is controlled through neural circuits in the brain. Molecular disturbances can lead to stereotypical behavior, as seen in neuropsychiatric disorders such as obsessive-compulsive and autism spectrum disorders.

A research team has now demonstrated that the absence of two proteins, Intersectin1 and Intersectin2, in mice leads to disrupted neural signaling and compulsive repetitive behavior, which is also observed in patients with Intersectin 1 mutations. This supports the idea that such defects can cause neuropsychiatric diseases. The study is published in Proceedings of the National Academy of Sciences.

Our brain is essentially our body’s computer...
