Antiplatelets: 1 person, 1 dose?

A new trial shows that standard-dose clopidogrel is as effective as double the dose for preventing cardiovascular events in patients with high on-treatment platelet reactivity. Researchers argue that a personalized approach to antiplatelet therapy may be more beneficial, warranting further investigation.

Hopkins team discovers how DNA changes

Researchers identified a step-by-step process involving TET1 and Apobec1 that converts methylated cytosine into hydroxymethylated cytosine, indicating a potential unified mechanism for DNA methylation status change. The discovery has implications for understanding diseases associated with epigenetic abnormality.

Filtering out pesticides with E. coli

Researchers in China have developed a genetically modified form of E. coli that can extract toxic pesticides like parathion and methyl parathion from the air with high efficiency. The biofilter system has shown average removal efficiencies of up to 95.2% for parathion and 98.6% for methyl parathion.

Women more likely to self-medicate

A research study by the Rey Juan Carlos University in Madrid found that women are more likely to self-medicate than men in Spain. The study, published in Pharmacoepidemiology and Drug Safety, revealed that 20.17% of Spaniards use medication without a medical prescription, with women accounting for 16.93% of those cases.
