Nigerian botanicals restore hormonal balance and fight menstrual pain in preclinical study

Researchers tested five Nigerian medicinal plants in female rats and found that these botanicals reversed MSG-induced hormonal imbalance, oxidative stress, and lipid disruptions linked to dysmenorrhea. The findings support further investigation of plant-based therapies for menstrual pain and related metabolic risks.

Heart failure and atrial fibrillation at the time of mitral valve repair linked to worse outcomes

Patients with heart failure and atrial fibrillation (AF) at the time of mitral transcatheter edge-to-edge repair (M-TEER) for severe mitral regurgitation are more than twice as likely to die or be rehospitalized for heart failure, compared to patients without AF.

Chronic venous insufficiency linked to increased cardiovascular disease and mortality risk

In light of reports from the White House that President Donald J. Trump has been diagnosed with Chronic Venous Insufficiency (CVI), the American Heart Association is sharing important information on the condition and its association with cardiovascular risk factors, disease and increased risk of death.

TTUHSC researcher focuses on how brain endothelial cells handle stressors of neuroinflammation

Each year in the U.S., approximately 2.5 million people suffer traumatic brain injuries (TBIs). About 50,000 of these injuries will result in death, and more than 80,000 will lead to permanent disability.

Research explains how low sodium weakens the heart’s electrical signals

New research explains how low levels of the electrolyte sodium in the blood can disrupt the timing of the heartbeat in patients taking widely used rhythm-control medications such as flecainide, which is commonly prescribed for atrial fibrillation and other fast or irregular heart rhythms.

Computational biology unlocks rules of tissue self-organization

A team of researchers at ChristianaCare's Helen F. Graham Cancer Center & Research Institute and the University of Delaware believe they've found an answer.

Study highlights dangers of vascular injuries in young gunshot victims

A study presented today at the Society of NeuroInterventional Surgery's (SNIS) 22nd Annual Meeting found that almost half of gunshot wound injuries to the brain in children and young adults include penetrating cerebrovascular injuries (PCVIs).

Popular sugar substitute could raise the risk of blood clots and stroke

From low-carb ice cream to keto protein bars to "sugar-free" soda, the decades-old sweetener erythritol is everywhere.

Pregnancy increases rupture risk for brain arteriovenous malformations

At the Society of NeuroInterventional Surgery's (SNIS) 22nd Annual Meeting today, researchers presented findings about how pregnancy can worsen the rupture risk for brain arteriovenous malformations, abnormal connections between arteries and veins whose rupture can result in serious brain injury or death.

How five months in Tibet changed the heart and lungs of Beijing workers

Long-term exposure to very high altitude significantly reduces cardiopulmonary function in healthy adults from lowland regions, as shown by declines in aerobic capacity and efficiency after five months in Lhasa, China.

PREVENT equations accurately predict heart disease in diverse Asian and Hispanic groups

Cardiovascular disease (CVD) risk prediction models have improved the ability to stratify adults across the CVD risk spectrum. Researchers at Sutter Health and colleagues at Stanford University tested the performance of the American Heart Association's Predicting Risk of CVD Events (PREVENT) equations in the six largest Asian subgroups as well as in Mexican and Puerto Rican Hispanic subgroups.

How a simple blood test can forecast future health risks

Plasma proteomics reveals that the biological ages of key organs, especially the brain and immune system, strongly predict the risk of future disease and early death. These organ-specific “clocks” provide a new tool for identifying those at highest risk and personalizing preventive care.

Weight loss wipes out senescent fat cells but leaves immune scars, study finds

Researchers have mapped human fat tissue at single-cell resolution, uncovering how obesity alters cellular stress, inflammation, and tissue structure. Weight loss reverses much of this damage, especially senescence in fat and vascular cells, but leaves some immune dysfunction behind.
