Groundbreaking Biomaterial Heals Tissues From the Inside Out

Posted by in categories: bioengineering, neuroscience

The substance can be administered via intravenous injection and holds the possibility of being used in the treatment of conditions such as heart attacks and traumatic brain injury, among others.

An innovative biomaterial has been developed that, when injected intravenously, reduces inflammation and stimulates cell and tissue repair. The efficacy of this biomaterial in treating heart attack-induced tissue damage was demonstrated through successful testing on both rodent and large animal models. The researchers also provided proof of concept, based on a rodent study, suggesting that the biomaterial may prove beneficial in the treatment of traumatic brain injury and pulmonary arterial hypertension.

“This biomaterial allows for treating damaged tissue from the inside out,” said Karen Christman, a professor of bioengineering at the University of California San Diego, and the lead researcher on the team that developed the material. “It’s a new approach to regenerative engineering.”

Vascular dementia: Could a blood biomarker aid early diagnosis?

Posted by in categories: biotech/medical, neuroscience

A recent study suggests that heightened levels of a biomarker called placental growth factor (PlGF) in a person’s blood may help diagnose vascular dementia in its early stages.

New Study Finds Neurons Derived from Stem Cells Predict Psychosis and Cognitive Deficits in Individuals with Schizophrenia

Posted by in categories: biotech/medical, neuroscience

Baltimore, Md. (January 11, 2022) – In a breakthrough that holds significant promise for early diagnosis and better treatment of psychiatric illness, researchers have for the first time used neurons derived from human stem cells to predict the cardinal features of a psychiatric illness, such as psychosis and cognitive deficits in patients with schizophrenia.

A study published today in the Proceedings of the National Academy of Sciences (PNAS) by scientists at the Lieber Institute for Brain Development/Maltz Research Laboratories (LIBD) shows that the clinical symptoms of individuals with schizophrenia can be predicted by the activity of neurons derived from the patients’ own stem cells.

This connection — between the physiology of cells and symptoms like delusions, hallucinations and altered cognition— has never been made before. That is, no other study has demonstrated a robust association between neuronal models derived from a patient’s stem cells and clinically relevant features of the psychiatric disorder in the same person.

Crabs Have Evolved Five Separate Times—Why Do the Same Forms Keep Appearing in Nature?

Posted by in categories: biotech/medical, neuroscience

It’s not only body forms that evolve independently, but also organs and other structures. Humans have complex camera eyes with a lens, iris and retina. Squid, and octopuses, which are molluscs and more closely related to snails and clams, also evolved camera eyes with the same components.

Eyes more generally may have evolved independently up to 40 times in different groups of animals. Even box jellyfish, which don’t have a brain, have eyes with lenses at the bases of their four tentacles.

The more we look, the more we find. Structures such as jaws, teeth, ears, fins, legs and wings all keep evolving independently across the animal tree of life.

Scientists Found a Multidimensional Universe Right Inside Our Brain

Posted by in categories: mathematics, neuroscience

Experts have discovered that the human brain has structures and forms with up to 11 dimensions, which is a remarkable finding. “We discovered a realm that we had never envisaged,” neuroscientists said of the finding. Algebraic topology mathematical approaches have aided researchers in discovering structures and multidimensional geometric spaces in brain networks. A recent study, according to specialists, has demonstrated that the human brain has structures and forms with up to 11 dimensions. According to Science Alert, our brains have an estimated 86 billion neurons, with many connections from each cell stretching in every imaginable direction, making a super-vast cellular network that SOMEHOW allows us to think and be conscious.

A framework characterizing the cardio-behavioral responses associated with fear and anxiety

Posted by in categories: biotech/medical, neuroscience

Anxiety disorders are becoming increasingly common, with estimates suggesting that almost one in three people in the U.S. will experience high levels of anxiety at some point in their life. Anxiety is essentially a feeling of unease, worry or psychological discomfort, typically associated with catastrophic thoughts about a real or imagined future life event.

When they are anxious, humans experience the same sensations and physiological responses they would feel when they are afraid of a real and immediate threat, such as a lion chasing them, an ongoing natural disaster, and so on. To better support patients with anxiety disorders, neuroscientists and psychology researchers have been trying to understand the neural underpinnings of fear and anxiety for many years.

Ultimately, both fear and anxiety tend to promote defensive behaviors in response to real or imaginary threats, respectively. The most widely documented among these are the so-called freeze (i.e., staying still), flight (i.e., avoiding a feared situation or escaping), fight (i.e., arguing or becoming aggressive) and fawn (i.e., overpleasing or submitting to another human to avoid the escalation of conflict).
