Researchers engineer cells to destroy malignant tumor cells but leave the rest alone

Credit: McMaster University HAMILTON, ON June 28, 2021 Researchers at McMaster University have developed a promising new cancer immunotherapy that uses cancer-killing cells genetically engineered outside the body to find and destroy malignant tumors. The modified natural killer cells can differentiate between cancer cells and healthy cells that are often intermingled in and around tumors, destroying only the targeted cells. The natural killer cells ability to distinguish the target cells, even from healthy cells that bear similar markers, brings new promise to this branch of immunotherapy, say members of the research team behind a paper published in the current issue of the journal

Easy Heart Procedure Can Help Prevent Strokes

The simple operation reduces the risk of strokes by more than one-third in patients with atrial fibrillation. Tim HayesContributing Editor, Healthcare Packaging Healthcare Packaging May 26th, 2021 According to a recent Sci-Tech Dailyarticle, a simple procedure could significantly reduce the risk of stroke in patients with heart arrhythmia. Researchers at McMaster University found that removing the left atrial appendage reduces the risk of stroke by more than a third. The left atrial appendage is an unused finger-shaped tissue that’s leftover from when the heart is formed as an embryo. It has a tendency to trap blood and form clots. The team’s study tracked more than 4,800 people in 27 countries who are living with atrial fibrillation and taking blood thinners. Consenting patients undertaking cardiopulmonary bypass surgery were chosen at random to also have their left atrial appendage removed. Those who received the extra procedure were about a third less likely to suffer a
