Man sees deadly brain tumour shrink by half thanks to new treatment

Link :

Glioblastoma, an aggressive and often fatal form of brain cancer, has long posed a formidable challenge to doctors and patients alike. Yet, a groundbreaking clinical trial is offering a glimmer of hope, capturing global attention for its potential to revolutionize cancer treatment. A 62-year-old engineer, faced with a grim prognosis, has experienced something extraordinary—his tumour has shrunk significantly in a matter of weeks. This remarkable outcome marks the beginning of a journey that could redefine how we treat one of the most challenging cancers. What makes this approach so promising, and how could it change the future for patients?

Glioblastoma, often referred to as glioblastoma multiforme (GBM), is the most aggressive and common form of primary brain cancer in adults. Originating from glial cells—specifically astrocytes that support nerve cells—this malignancy is notorious for its rapid growth and diffuse infiltration into surrounding brain tissue, making complete surgical removal challenging.

Scalable aluminum surfaces method enables advancements in cooling, self-cleaning and anti-icing technologies

Many cells in our body have a single primary cilium, a micrometer-long, hair-like organelle protruding from the that transmits cellular signals. Cilia are important for regulating cellular processes, but because of their small size and number, it has been difficult for scientists to explore cilia in brain cells with traditional techniques, leaving their organization and function unclear.

In a series of papers appearing in Current Biology, the Journal of Cell Biology, and the Proceedings of the National Academy of Sciences, researchers at HHMI’s Janelia Research Campus, the Allen Institute, the University of Texas Southwestern Medical Center, and Harvard Medical School used super high-resolution 3D electron microscopy images of mouse brain tissue generated for creating connectomes to get the best look yet at .

Fighting Antibiotic Resistance with Computer-Driven Precision Medicine

How can computer models help medical professionals combat antibiotic resistance? This is what a recent study published in PLOS Biology hopes to address as a team of researchers from the University of Virginia (UVA) developed computer models that can be used to target specific genes in bacteria to combat antimicrobial resistant (AMR) bacteria. This study has the potential to help scientists, medical professionals, and the public better understand innovative methods that can be used to combat AMR with bacterial diseases constantly posing a risk to global human health.

For the study, the researchers used computer models to produce an assemblage of genome-scale metabolic network reconstructions (GENREs) diseases to identify key genes in stomach diseases that can be targeted with antibiotics to circumvent AMR in these bacterial diseases. The researchers validated their findings with laboratory experiments involving microbial samples and found that a specific gene was responsible for producing stomach diseases, thus strengthening the argument for using targeted antibiotics to combat AMR.

“Using our computer models we found that the bacteria living in the stomach had unique properties,” said Emma Glass, who is a PhD Candidate in Biomedical Engineering at UVA and lead author of the study. “These properties can be used to guide design of targeted antibiotics, which could hopefully one day slow the emergence of resistant infections.”

People left horrified after finding out your tonsils can grow back despite being removed

That was quite the scare for one US woman who was told she needed to have hers removed, despite having had them removed 40 years earlier.

Katy Golden told CNN: “I knew that there was some sort of little flap or something that’s been there for years, but I didn’t realize what it was. I just thought, ‘I’m not a doctor myself. I don’t know much about mouth structure. That’s just how it is’.”

Researchers find new way to ‘Starve’ Prostate Cancer Tumors at the Cellular Level

New research by a team of Indiana University School of Medicine scientists and their collaborators has uncovered a novel vulnerability in prostate cancer animal models that starves prostate tumors of critical nutrients and stunts their growth, which could lead to the development of new treatments for the deadly disease.

Led by IU School of Medicine’s Kirk Staschke, Ph.D., assistant research professor of biochemistry and molecular biology, and Ronald C. Wek, Ph.D., Showalter Professor of Biochemistry, the study was recently published in Science Signaling.

Prostate cancer is a leading cause of cancer deaths in American men. Current treatments target the hormone testosterone, which prostate cancer cells need to grow. Unfortunately, prostate tumors frequently become resistant to these treatments, leaving doctors with few options to stop the disease.
