Researchers uncover new role of mutant proteins in some of the deadliest cancers

NIH/National Cancer Institute
Peer-Reviewed Publication

Researchers at the National Institutes of Health (NIH) and their collaborators have discovered a new way in which RAS genes, which are commonly mutated in cancer, may drive tumor growth beyond their well-known role in signaling at the cell surface. Mutant RAS, they found, helps to kick off a series of events involving the transport of specific nuclear proteins that lead to uncontrolled tumor growth, according to a study published November 11, 2024, in Nature Cancer.

Bystander CPR up to 10 minutes after cardiac arrest may protect brain function

American Heart Association
Reports and Proceedings

The sooner a lay rescuer (bystander) starts cardiopulmonary resuscitation (CPR) on a person having a cardiac arrest at home or in public, up to 10 minutes after the arrest, the better the chances of survival and brain protection, according to an analysis of nearly 200,000 out-of-hospital cardiac arrest cases in the U.S. from 2013 to 2022.

911 dispatcher assistance improved chances of receiving bystander CPR

American Heart Association
Reports and Proceedings

A study of nearly 2,400 cardiac arrest cases in North Carolina found that when emergency dispatchers (telecommunicators) provided cardiopulmonary resuscitation (CPR) instructions to 911 callers, people were more likely to provide aid for both men and women.

Resolving the developmental mechanisms of cardiac microthrombosis of SARS-CoV-2 based on single-cell transcriptome analysis

Science China Press
Peer-Reviewed Publication

In a paper published in Science China Life Sciences, professor Wang Guoqing's team at Jilin University conducted single-cell sequencing analysis on right ventricular free wall tissue from healthy donors and patients with characteristic coagulation abnormalities of COVID-19, revealing the mechanism of cardiac microthrombosis formation in patients after SARS-CoV-2 infection.

Patients may become unnecessarily depressed by common heart medicine

Uppsala University
Peer-Reviewed Publication

All patients who have had a heart attack are typically treated using beta blockers. According to a Swedish study conducted earlier this year, this drug is unlikely to be needed for those heart patients who have a normal pumping ability. Now a sub-study at Uppsala University shows that there is also a risk that these patients will become depressed by the treatment.
