A study found that children whose mothers experience postnatal depression are more likely to exhibit violent behavior, particularly in boys. The link is associated with attention and emotional regulation problems, which can lead to a higher propensity for violence.
A study by French researchers found that young breast cancer patients who undergo lumpectomy have a higher risk of late recurrence compared to those who opt for mastectomy. The risk is particularly high among women under 40 years old.
Researchers demonstrate that removing beta-1 integrin gene prevents breast cancer growth in mice, halting tumor progression and even regressing advanced cancers. However, some tumors spontaneously recur over time, highlighting the need for further investigation into mechanisms of resistance.
A recent study published in Public Library of Science Biology has identified the GAD2 gene as a strong candidate for human obesity. The research suggests that an active form of this gene contributes to excessive hunger and eating behaviors, particularly in individuals with a higher risk of obesity.
