For more than a decade, scientists have been testing a class of cancer drugs known as BET inhibitors with great promise. The science behind them seemed strong. Many tumors depend on oncogenes being switched on with the help of ‘bromo-terminal and distal end domain’ (BET) proteins, so it was hoped that blocking these proteins would slow cancer growth. In laboratory experiments, this approach often worked well. But in real patients, the effects were less impressive: efficacy was modest, side effects were noticeable, and there was no reliable way to predict who would respond. Now, researchers at the Max Planck Institute…

Different species may independently arrive at the same biological solution. This is a phenomenon known as parallel evolution. Researchers at Osaka Metropolitan University (OMU) have discovered that dragonflies detect red light in a way that is very similar to how mammals, including humans, do. This discovery could have implications far beyond insect biology, as many medical techniques rely on red light. Human vision relies on eye proteins called opsins. These proteins allow us to recognize different colors. We have three main types, each tuned to blue, green, or red wavelengths, which when combined provide full-color vision. Dragonflies are unique among…

A large-scale analysis from the United States associates unmarried status with increased cancer incidence for most cancers, highlighting how social and behavioral factors shape risk across the life course. Research: Marriage and cancer risk: A contemporary population-based study across demographic groups and cancer types. Image credit: Yuganov Konstantin / Shutterstock Recent research published in journals cancer research communication suggest that marital status may be associated with differences in cancer risk in the United States. Using population-level data, the researchers found that unmarried adults, especially black men, had significantly higher cancer rates for most cancers. The risk was 68% higher in…

The Barrow Neurological Institute has expanded its Barrow Neuroanalysis Center, nearly doubling dedicated research space to more than 18,000 square feet and bringing additional research programs into one location. The center expansion will add 8,317 square feet to the existing 10,099 square foot facility and will be located at Park Central in the Phoenix Medical Quarter. This expansion is important for neurological research. This will accelerate our ability to uncover further insights into environmental factors and healthcare access associated with neurological diseases, ultimately leading to efforts to reduce disparities and disease burden. ” Brad Russett, MD, FAAN, Chairman…

A recently published study from the University of Oklahoma and the University of Tulsa proposes a new model to explain why children’s nightmares persist over long periods of time and how treatments can be designed to break the nightmare cycle. This research frontier of sleepNow, I will introduce the Darkness Model, which memorizes the factors that prevent children from escaping chronic nightmares. Central to this model is the idea of ​​”nightmare efficacy,” or the idea that children can learn skills to rid themselves of nightmares and regain good sleep. The DARC-NESS model considers the mechanisms that maintain nightmares and the…

Two new vaccines to prevent tuberculosis (TB) are safe to use in adults and children, but do not protect against all forms of the disease, a large trial published in India has found. BMJ today. Tuberculosis remains a major global public health concern. In 2023, an estimated 10.8 million people worldwide will be reported to have tuberculosis, with the rate of new infections increasing by 4.6% between 2020 and 2020, highlighting the growing scale of the problem. BCG is currently the only vaccine approved for tuberculosis. However, while it is effective against severe tuberculosis in young children, it is not…

An economic analysis published in an open access journal suggests that quitting tobacco could bring a significant economic boost to the incomes of more than 20 million households in India. BMJ Global Health.The biggest impact will be felt in rural areas and the poorest households, but 7 million middle-income households will also benefit, estimates suggest. About 80% of tobacco users live in low- and middle-income countries, where a significant portion of household income is spent on tobacco products, the researchers said. They added that the treatment of tobacco-related diseases and associated lost productivity due to illness and premature death collectively…

Colorectal cancer is the second leading cause of cancer-related death worldwide. If detected early, it is often highly treatable. However, the main screening method used today, colonoscopies, can be expensive and uncomfortable, making many people reluctant to undergo the test on time. Researchers at the University of Geneva (UNIGE) have developed a new approach that could change this. They used machine learning to create the first detailed catalog of all human gut bacteria with enough precision to reveal how different microbial subgroups function in the body. This information was then used to detect colorectal cancer based on bacteria in a…

A new commentary highlights preclinical evidence that inhibiting key amino acids in combination with polyamine inhibitors can cause aggressive neuroblastoma cells to mature rather than proliferate. Commentary: Rewire your cancer by changing your diet. Image credit: Nemes Laszlo / Shutterstock Recently published explanatory articles New England Medical Journal Highlights how targeted dietary manipulation can reprogram tumor biology. The possibility that diet may improve cancer treatment outcomes is of great interest across researchers, clinicians, and the patient community. Mechanistic studies have shown that some dietary manipulations can affect tumor metabolism and the tumor microenvironment, enhancing response to conventional treatments such as…

A three-dimensional experimental system has been developed to study the response to drugs in low-grade gliomas, a common central nervous system tumor in children. The project, developed by the University of Trento, the Bambino Gesu Children’s Hospital and the Sapienza University of Rome, is a breakthrough in the research, understanding and treatment of this disease. The results have just been published in an international journal molecular cancer. Gliomas are tumors of the central nervous system that originate from glial cells that support neurons in the brain. Gliomas, which are less aggressive and slow to grow, are more common in children…
