Distinct microbial signature identified in pediatric Crohn's disease

NYU researchers have found a "microbial signature" of pediatric Crohn's disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn's patients harboring more pro-inflammatory bacteria and less protective bacteria.

New strategy may improve ovarian cancer treatment outcomes

A new study published by Mayo Clinic researchers suggests that ovarian cancer cells quickly activate a survival response after PARP inhibitor treatment, and blocking this early response may make this class of drugs work better.

Study examines the relationship between leukocyte telomere length and age-related cataract

Cataracts remain the leading cause of blindness worldwide among adults over 50, despite major advances in surgical treatment.

Novel DAMP markers advance myocardial contusion detection

Researchers are exploring a new generation of biochemical markers that may help clinicians detect myocardial contusion. A frequently overlooked form of heart injury caused by blunt chest trauma, earlier and more accurately.

Brain circuit links past experiences to appetite control

Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate contextual information into appetite control.

Study highlights key role of non-contractile cardiac cells in persistent atrial fibrillation

Atrial fibrillation (AF), the most common chronic cardiac arrhythmia in clinical practice, is very challenging to treat once it becomes persistent, after which spontaneous return to normal rhythm becomes highly unlikely.

Boosting good immune cells can help fight insulin resistance and diabetes

Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes – by boosting a special type of "good" immune cell in fat tissue.

Early cognitive stimulation preserves memory in Alzheimer’s

A team from the Institute of Neurosciences of the University of Barcelona (UBneuro) has discovered that early and sustained cognitive stimulation can help preserve brain connectivity and memory in Alzheimer's disease, even in advanced stages of the pathology.

Researchers identify a previously unknown cellular barrier in the brain

VIB and Ghent University researchers have identified and characterized a previously unknown cellular barrier in the brain, which sheds new light on how the brain is protected from the rest of the body.

Aligning overnight fasting with sleep improves heart health

A new Northwestern Medicine study has personalized overnight fasting by aligning it with individuals' circadian sleep-wake rhythm - an important regulator of cardiovascular and metabolic function - without changing their caloric intake.

SLAMF6 discovery offers hope for non-responding cancer patients

Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumors – and, in mice, they've found a way to neutralize it.

Blood omics data forecasts trauma outcomes with high accuracy

Researchers at the University of Colorado Anschutz have developed a way to predict how trauma patients will recover, days before complications come to fruition, by analyzing the molecules in their blood.

Visual experience shapes feedback wiring in the brain

Visual experience triggers the formation of a web of neural connections in different brain areas in order to make sense of the world – and in particular, of feedback connections, which send information from higher-level visual centres back to earlier ones.

Neuron lattice structure may guard against neurodegeneration

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is essential for learning, memory and basic neural upkeep.

Nanovaccine design boosts immune attack on HPV tumors

Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure.

Study uncovers immune trigger behind vaccine-induced immune thrombocytopenia and thrombosis

A global research collaboration of scientists from McMaster University (Canada), Flinders University (Australia) and Universitätsmedizin Greifswald (Germany) uncovered why a small number of people developed dangerous blood clots after either receiving certain COVID‑19 vaccines or experiencing a natural adenovirus infection, and the answer lies in an unexpected case of misdirected targeting by the immune system.
