PHOENIX — High-grade gliomas are cancerous tumors that spread quickly in the brain or spinal cord. In a new study led by Mayo Clinic, researchers found invasive brain tumor margins of high-grade glioma (HGG) contain biologically distinct genetic and molecular alterations that point to aggressive behavior and disease recurrence. The findings suggest insights into potential treatments that could modify the course of the disease. The study published in Nature Communications, profiled 313 tumor biopsies from 68 HGG patients using genomics (study of genes), ...

Depending on their location, cancer cells within a three-dimensional (3D) tumor structure can have different microenvironments. Cells in the core of the tumor receive less oxygen (hypoxia) and nutrients than those in the periphery. These varying conditions can drive differences in cell growth rates and drug sensitivities, highlighting the need to study 3D tumor models in lab settings. Until recently, conventional methods used to create such tumor spheroids were time-consuming, produced inconsistent results and involved high setup costs. Investigators at Brigham and Women’s Hospital, a founding ...

Ann Arbor, January 30, 2024 – Experiencing a pregnancy from sexual violence is common in the United States, according to research conducted by investigators at the Centers for Disease Control and Prevention (CDC) reported in the American Journal of Preventive Medicine, published by Elsevier. Nearly six million women in the United States who were raped, sexually coerced (defined as non-physically forced unwanted penetration), or both became pregnant as a result. This equates to about one in twenty American ...

The two most common obesity surgeries – gastric bypass and gastric sleeve – have few short-term complications and are equivalent in that sense. These are the findings of a study conducted at the University of Gothenburg. Every year, around 5,000 obesity surgeries are performed in Sweden. The person undergoing surgery will normally have a BMI of at least 40, or 35 if they also have other serious medical conditions related to obesity. The most common procedures are gastric bypass, where a large part ...

A new study led by researchers at UCLA may change the way clinicians and scientists understand, diagnose and treat placenta accreta spectrum disorder, a serious condition in which the placenta fails to separate from the uterus at birth, jeopardizing the life and health of both mother and baby. Researchers previously believed that certain overly invasive placental cells, called trophoblasts, were responsible for keeping the connection intact. But this new research, which identifies genetic and cellular changes within single cells where the placenta ...

UNIVERSITY PARK, Pa. — Biological systems can behave as siblings in several ways, including by borrowing something and never giving it back. That appears to be what the human immune system did with a protein that now helps bind and regulate the subunits that make up antibodies, according to a multi-institute research collaboration. They found that, before the immune system evolutionarily co-opted it, the protein originally belonged to gene family responsible for directing cells to move to the right location at the right time to address specific functional needs. The researchers, including Kazuhiko Kawasaki, associate research professor of ...

When it comes to having surgery, older adults don’t just base their decision on how much pain they’ll feel and how quickly they’ll recover, a new study finds. Many also have serious concerns about how much they’ll have to pay out of their own pockets, how much work they’ll miss, and whether they’ll catch COVID-19 in the hospital or surgery center. And a majority of those who called themselves very concerned about these issues ended up not having an operation that they had considered having, the study finds. The percentage who didn’t go through with surgery was much lower among those who said they’d been very concerned about pain or the ...

Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that’s likely to get worse, according to experts, because it’s just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers in Drexel University’s College of Engineering are trying to give robotic assistants the tools to help inspectors with the job. Augmenting visual ...
