Researchers at UCSD use microscopic silicon chips with magnetic properties to control the movement of particles and cargo in oil droplets. This allows for efficient transport and manipulation of tiny biological samples without pumps or channels.
Researchers found a clear correlation between female promiscuity and rapid evolution of the semenogelin protein in various primate species. This suggests that intense sexual competition drives genetic adaptation, with genes evolving faster in species with more promiscuous females.
A study of 43 families of sudden unexplained death victims found an inherited disease in 17 cases, while another pilot study showed yoga and meditation improved endothelial function. Strong social support was linked to lower blood pressure, while adherence to guidelines for angioplasty procedures led to better outcomes.
A new gene therapy technique has successfully treated irregular heart rhythms in pigs, using a 'painting' method to deliver the therapy. The technique, which uses a plastic, gel-like substance to contain the gene therapy, shows promise for treating atrial fibrillation, a common heart condition.
A recent study found that maintaining a stable weight, even for obese individuals, significantly reduces the risk of heart disease. The study, which followed over 2,500 young adults for 15 years, revealed that those who gained weight were nearly five times more likely to develop metabolic syndrome and related health issues.
Research by the American Heart Association found that overweight men spent $18.41 per month on coronary heart disease-related prescriptions, compared to $9.89 for normal-weight men. The study also showed a significant increase in costs for obese men due to various health issues such as high blood pressure and sleep apnea.
A recent study found that nearly 82% of participants who gained 15 pounds or more over 15 years developed metabolic syndrome, a group of metabolic risk factors linked to increased heart disease risk. Weight stabilization is recommended as a key public health strategy.
A new study found that long-term air pollution exposure contributes to cardiovascular problems at an early stage of the disease, enhancing atherosclerosis. The strongest association was seen in women over 60, with a 15.7% increase in CIMT for every 10 ug/m3 increase in PM2.5.
Duke researchers found that coronary artery bypass surgery and angioplasty with stenting have similar long-term mortality rates. Despite reducing the need for repeat procedures, stents do not save lives, according to cardiologist David Kandzari.
