Source of hidden consciousness in ‘comatose’ brain injury patients found

Researchers have identified patterns of brain injury that underlie hidden consciousness, a phenomenon where brain-injured patients appear unconscious despite having some level of awareness. The study found that all patients with hidden consciousness had intact brain structures related to arousal and command comprehension.

A boost in dopamine during adolescence permanently amplifies dopamine function, impulsivity, and aggression in mice

Researchers found that blocking dopamine transporters during mid-adolescence increases adult aggression, impulsivity, and the behavioral response to amphetamine in mice. Artificially stimulating dopaminergic neurons also exacerbated impulsive behavior in tasks. The study suggests potential harm from stimulant exposure in healthy teens ...

New research shows babies’ immunological weak spot and strength

Researchers at Columbia University found that babies' immune cells develop slowly and are not fully mature until around 4-6 years old. This makes them more susceptible to respiratory infections, but also enables them to respond to new pathogens in a unique way, such as the formation of bronchus-associated lymphoid tissue (BALT).

Could drops replace eye injections for retina disease?

Researchers at Columbia University Irving Medical Center have discovered that an experimental eye drop treatment can reduce swelling and improve blood flow in the retina of mice with retinal vein occlusion, a common eye disease affecting up to 2% of people over age 40. The study found that the eye drops prevented neurons from deteriora...

Drug to treat cannabis use disorder shows promise in clinical trial

A Phase 2a clinical trial found that AEFO117 significantly reduced the effects of cannabis in daily smokers and decreased both positive mood effects and decision to use cannabis. The drug, developed by Aelis Farma, appears to counteract the high associated with THC without disrupting physiological and behavioral functions.

Food FARMacia breaks the link between food insecurity and obesity in children

A new study found that a Food FARMacia program, which provided free and healthy foods to families in need, was associated with reduced childhood obesity outcomes and improved household food security. The program, which operated mobile pantries twice a month, showed a clinically significant decline in childhood obesity risk factors afte...

Will revitalizing old blood slow aging?

Researchers at Columbia University Irving Medical Center have found that an anti-inflammatory drug can turn back time in mice and reverse some of the effects of age on the hematopoietic system. By targeting the aging niche, the study suggests a new strategy for maintaining healthier blood production in older adults.

Bioengineered skin grafts that fit like a glove

Researchers at Columbia University Irving Medical Center have developed a method to grow engineered skin in complex, three-dimensional shapes, making it possible to construct seamless 'glove' of skin cells that can be easily slipped onto a severely burned hand. The new skin grafts have better mechanical and functional properties than c...

Columbia researchers find link between serotonin and heart valve disease

A new study led by Columbia researchers discovered a link between serotonin and heart valve disease, specifically degenerative mitral regurgitation. The study found that patients taking selective serotonin reuptake inhibitors (SSRIs) were more likely to develop severe mitral regurgitation and require surgery at a younger age.

Rx for prolonged sitting: A five-minute stroll every half hour

A study by Columbia University exercise physiologists found that taking a five-minute walking break every 30 minutes can significantly lower blood sugar and blood pressure, while also reducing fatigue and improving mood. This regimen provided the most benefits, with only one minute of walking per hour providing modest benefits.

Rheumatoid arthritis drugs lower risk of heart disease

People with rheumatoid arthritis have a higher risk of cardiovascular disease due to inflammation. However, new research suggests that commonly used treatments for RA can also lower this risk by reducing arterial inflammation and disease activity. The study found that immunomodulators like methotrexate and TNFi drugs reduced heart dise...

Discovery of a molecular switch in pancreatic cancer cells that triggers metastatic disease

A study published in Molecular Cell has identified a protein, MSRA, whose level of expression acts as a molecular switch between primary cancer growth and metastasis in PDA cells. The researchers found that high levels of MSRA expression keep the growing cells as part of the primary tumor, while low levels trigger metastasis.

Genetic screening algorithm could identify people with kidney disease risk

A new algorithm can analyze thousands of genomic variants to estimate a person's risk of developing chronic kidney disease, with the highest scores indicating tripled risk compared to the general population. Early detection may prevent many cases of kidney failure and reduce the need for transplant or dialysis.
