Variations in glucose levels may indicate severity of heart attack damage

Research in Brazil found that glycemic delta, a measure of blood sugar variability, is associated with the size of the heart attack and the strength of heart contractions. The study suggests that high glycemic delta may be a biomarker for worse outcomes in patients who have experienced their first acute myocardial infarction.

Researchers achieve light-induced heterolytic hydrogen dissociation at ambient temperature

A research team developed a photochemical strategy to realize heterolytic H2 dissociation using gold-loaded titanium dioxide as a model photocatalyst. The reaction was driven by electron-hole pairs formed upon UV irradiation, producing reactive H2 species that selectively reduced polar functional groups.

Study confirms that inactive parents contribute to sedentary behavior in their children

A study by São Paulo State University found a direct association between adults' levels of physical activity and their children's sedentary behavior. Children of inactive parents tend to be more sedentary, but when mothers and fathers maintain an active routine, their children usually follow suit.

Researchers identify gene associated with deadly heart disease in golden retrievers

Golden retrievers are at risk of a fatal heart condition due to a genetic mutation in the Cardiac Troponin-I gene. The study, published in Circulation: Genomic and Precision Medicine, identified a single genetic variant that causes hypertrophic cardiomyopathy (HCM) and sudden death in dogs.

Intense light therapy may lower risk of myocardial injuries after non-cardiac surgery

A study published in Annals of Translational Medicine found that intense light therapy can lower troponin levels and increase ANGPTL4 protein, protecting heart tissue. The treatment may reduce the risk of myocardial injuries after non-cardiac surgery, which affects 20% of patients and increases one-year mortality rates.

Students with overprotective parents are more vulnerable to anxiety during their transition to university, researchers find

First-year university students with overly cautious parents experience increased anxiety when faced with stressful situations. The study found that overprotective parenting can lead to insecure attachment and poorer emotion regulation, making individuals more vulnerable to anxiety.

Beta-blockers reduced cardiovascular events in selected heart attack patients without heart failure in the BETAMI-DANBLOCK trials

The BETAMI and DANBLOCK trials found that beta-blocker therapy significantly reduced all-cause mortality and major adverse cardiovascular events in patients with myocardial infarction and preserved or mildly reduced left ventricular ejection fraction. The study also showed a notable decrease in the incidence of new MI.

Ash boosts biogas production

A recent study published in Biomass and Bioenergy found that ash can increase methane production in anaerobic digestion of biowaste, improving the quality of resulting fertilizers. Adding trace elements from ash can have a complex effect on the process, but it also increases plant growth and reduces acidity.
