The brain is more resilient than previously thought. In a groundbreaking experiment published in this week's issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in pig brains. The result challenges the notion that mammalian brains are fully and irreversibly damaged by a lack of oxygen.
A protein called p53 suppresses and kills cancer in people. However, a defective, mutant form of p53 helps cancer cells grow and multiply. Researchers at the University of Missouri have now found that a combination drug therapy reduces the spread of triple negative breast cancer to other locations of the body by 50 percent.
The World Health Organization (WHO) created the Surgical Safety Checklist over a decade ago, in an effort to reduce mortality after surgery. The BJS (British Journal of Surgery) has published a study that used a national database to look at the records of over 12 million patients.
Circulation and cellular activity were restored in a pig's brain four hours after its death, a finding that challenges long-held assumptions about the timing and irreversible nature of the cessation of some brain functions after death, Yale scientists report April 18 in the journal Nature.
Researchers have developed a high-tech support system that can keep a large mammalian brain from rapidly decomposing in the hours after death, enabling study of certain molecular and cellular functions. With funding through the NIH BRAIN Initiative, researchers developed a way to deliver an artificial blood supply to the isolated postmortem brain of a pig, preventing the degradation that would otherwise destroy many cellular and molecular functions and render it unsuitable for study.
Analysis of human remains from a Pre-Roman Celtic cemetery in Italy shows variations in funerary treatment between individuals that could be related to social status, but these variations were not reflected by differences in their living conditions. Zita Laffranchi of Universidad de Granada, Spain, and colleagues present these new findings in the open access journal PLOS ONE on April 17, 2019.
UBC researchers have determined the majority of men struggle when it comes to understanding the diagnosis and treatment of prostate cancer. Professors Joan Bottorff and John Oliffe are scientists with UBC's Men's Health Research Program. Together, while studying men's knowledge or literacy of prostate cancer, they realized many are in the dark when it comes to what they know about the disease. And, more importantly, what direction to take after diagnosis.
Offering universal late pregnancy ultrasounds at 36 weeks would benefit mothers and babies and could be cost saving. A new study shows that an additional routine ultrasound could eliminate undiagnosed breech presentation of babies, lower the rate of emergency caesarean sections, and improve the health of mothers and babies.
Mental health professionals treating children and young people with suicidal feelings should refer to 'suicide' explicitly to ensure they feel listened to, according to new research.
This study used data from a large national surveillance system from 2003 to 2016 to report on adolescent homicides committed by an intimate partner (current or former girlfriend or boyfriend or spouse) and to describe characteristics of the victims, perpetrators and incidents.
