Exercise, not liraglutide alone, drives vascular gains after obesity-related weight loss

A prespecified secondary analysis of the S-LiTE trial found that regular exercise reduced carotid artery wall thickness and circulating levels of inflammatory cytokines in adults with obesity who had already achieved substantial diet-induced weight loss. Liraglutide alone did not significantly improve these vascular or inflammatory markers, while exercise plus liraglutide also improved endothelial function biomarkers.

Transfemoral J-Valve device improves symptoms in severe aortic regurgitation patients

New research simultaneously published today in JSCAI and presented at New York Valves 2026 reported favorable one-year outcomes in patients with symptomatic severe aortic regurgitation following treatment with the investigational J-Valve Transfemoral System.

High-dose DHA reaches the brain but fails to protect memory

High-dose DHA effectively increased brain levels in older adults at Alzheimer's risk, but did not lead to cognitive or structural brain health improvements.

Study identifies key fibrotic cells driving hypertrophic scars

Hypertrophic scars (HS) are abnormal outcomes of wound healing, marked by excessive extracellular matrix (ECM) deposition and impaired scar remodeling.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Modulating pathogenic scar cells promotes spinal cord regeneration

SCI often causes long-term motor and sensory deficits because the damaged tissue does not simply heal like many peripheral tissues.

New eye imaging technology captures clearer details of retina

Modern OCT devices can look inside the eye without a scalpel - but they do not always capture everything that matters. Some critical information is simply lost, blurred by scattered photons.

Zebrafish model unlocks new insights into hereditary brain disease

CADASIL, an inherited disease caused by mutations in the NOTCH3 gene, damages the brain’s small blood vessels, leading to strokes, cognitive decline, and early dementia.

Melatonin improves skin flap survival by reducing ferroptosis

Random-pattern skin flaps are widely used to repair defects caused by trauma, burns, tumor removal, and other injuries because they can be designed without depending on a single named blood vessel.

Micro and nanorobots could transform blood clot treatment

Newer tethered devices address some of these limitations: the "milli‑spinner" thrombectomy device applies compressive and shear loading to compact a clot to about 10% of its original volume, enabling ultrafast removal even in pulmonary and cerebral arteries (in vitro and porcine studies).

Landmark study confirms long-term durability of Ross procedure for aortic valve replacement

The Ross procedure, a highly specialized option for aortic valve replacement, is associated with significant long-term durability and excellent outcomes in a wide range of adult patients with aortic valve disease.

Lifetime estrogen exposure linked to improved brain health in women

Researchers from the University of Kansas have shown a link between reproductive hormone exposure throughout life and brain health in 459 women aged 65 to 80.

Researchers identify molecular cause of age-related cognitive decline

A research team from University Hospitals, Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center has identified a critical molecular cause of age-related cognitive decline, potentially paving the way for new treatments to protect brain health as we age.

Skin barrier monitoring predicts necrosis after skin flap surgery

Random-pattern skin flaps (RPSFs) receive blood mainly from small subcutaneous vessels rather than a defined axial vessel, leaving them vulnerable to ischemia and hypoxia after surgery.

Natural molecule erucamide helps slow progressive retinal degeneration

Many conditions that cause vision loss share a common feature: the gradual breakdown of the retina, the light-sensing tissue at the back of the eye.

Review outlines how donor imaging improves liver transplantation outcomes

Liver transplantation often depends on decisions made under pressure. In deceased donation, teams must quickly judge whether a liver is suitable, whether fat accumulation could threaten graft function, and whether unexpected vascular anatomy may complicate procurement or implantation.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Caregivers experience food insecurity during hospitalization of sick children

Researchers at Wake Forest University School of Medicine found caregivers of children hospitalized for cancer and blood disorders may experience food insecurity during their child's stay, even if they don't face that issue at home, and it could be linked to longer stays.

Epigenetic drugs improve blood vessel health in obesity and diabetes

People with obesity and type 2 diabetes are at high risk of blood vessel damage. This risk depends not only on the genes a person carries, but also on how they are "read".

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.
