  • Titanium particles are common around dental implants

    Titanium particles are common around dental implants

    Titanium micro-particles in the oral mucosa around dental implants are common. This is shown in a new study from the University of Gothenburg, which also identified 14 genes that may be affected by these particles.

    Registry data indicate that about five percent of all adults in Sweden have dental implants — and potentially also titanium particles in the tissue surrounding the implants. According to the researchers, there is no reason for concern, but more knowledge is needed.

    “Titanium is a…

  • Wildfire recovery: What victims say they need most

    Wildfire recovery: What victims say they need most

    It’s been three months since the start of a devastating series of wildfires that raged through Los Angeles from Jan. 7 to Jan. 31. As victims pick up the pieces of their lives, a study published in Environmental Research: Health from the UC Davis School of Medicine offers insights into what victims may need in the short and long term.

    “Understanding the community needs and impacts that arise during and after wildfires is crucial to identifying the timing, extent and types of assistance that…

  • Advanced imaging reveals mechanisms that cause autoimmune disease

    Advanced imaging reveals mechanisms that cause autoimmune disease

    People who suffer from the autoimmune disease myasthenia gravis experience muscle weakness that can affect any of the muscles we use to blink, smile or even move our body around.

    Researchers have known that the disease is caused by miscommunication between nerves and muscles. The body’s immune system mistakenly produces “autoantibodies,” or antibodies that attack its own tissues and proteins. In the case of myasthenia gravis, the body produces autoantibodies that target acetylcholine…

  • New insights into neurodegeneration using human ‘mini brains’

    New insights into neurodegeneration using human ‘mini brains’

    Researchers at The Ohio State University Wexner Medical Center and College of Medicine have discovered a new way that neurons act in neurodegeneration by using human neural organoids — also known as “mini-brain” models — from patients with frontotemporal lobar degeneration (FTLD).

    Understanding this new pathway could help researchers find better treatments for FTLD and Alzheimer’s, the two most common forms of dementia that lead to cognitive decline.

    Researchers used advanced techniques to…

  • More opportunities to test for Alzheimer’s using new analytical method

    More opportunities to test for Alzheimer’s using new analytical method

    Researchers at Lund University and Washington University have identified a blood marker that reflects the amount of Alzheimer’s pathology in the brain. This discovery may play a key role in determining who is most likely to benefit from the new Alzheimer’s drugs.

    In brief:

    • The blood-based marker (P-tau217) may start to change several years before the onset of Alzheimer’s symptoms. The marker can be measured using a simpler and cheaper analytical method.

    • Compared with a highly…

  • Master regulator blocking immunotherapy, paving the way for a new lung cancer treatment

    Master regulator blocking immunotherapy, paving the way for a new lung cancer treatment

    Immune checkpoint inhibitors, a class of immunotherapies that help immune cells attack cancer more effectively, have revolutionized cancer treatment. However, fewer than 20% of patients respond to these treatments, highlighting the urgent need for new strategies tailored to both responders and non-responders.

    KAIST researchers have discovered that ‘DEAD-box helicases 54 (DDX54)’, a type ofRNA-binding protein, is the master regulator that hinders the effectiveness of immunotherapy — opening…

  • Finding cancer's 'fingerprints'

    Finding cancer's 'fingerprints'

    Cancer diagnoses traditionally require invasive or labor-intensive procedures such as tissue biopsies. Now, research reveals a method that uses pulsed infrared light to identify molecular profiles in blood plasma that could indicate the presence of certain common cancers. In this proof-of-concept study, blood plasma from more than 2,000 people was analyzed to link molecular patterns to lung cancer, extrapolating a potential ‘cancer fingerprint.’

  • Starch-based microplastics could cause health risks in mice

    Starch-based microplastics could cause health risks in mice

    Wear and tear on plastic products releases small to nearly invisible plastic particles, which could impact people’s health when consumed or inhaled. To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study published in ACS’ Journal of Agricultural and Food Chemistry shows how animals consuming particles from this alternative material developed health problems such as liver damage and gut microbiome imbalances.

    “Biodegradable…

    long-term effects of obesity on brain and cognitive health

    With the global prevalence of obesity on the rise, it is crucial to explore the neural mechanisms linked to obesity and its influence on brain and cognitive health. However, the impact of obesity on the brain is complex and multilevel. To address this, Prof. Anqi QIU, Professor of the Department of Health Technology and Informatics at the Hong Kong Polytechnic University (PolyU) and Global STEM Scholar, has unveiled novel research to advance our understanding of the neural mechanisms…

  • Scientists complete largest wiring diagram and functional map of the brain to date

    Scientists complete largest wiring diagram and functional map of the brain to date

    From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a portion of the brain. In 1979, famed molecular biologist, Francis Crick, stated that it would be “[impossible] to create an exact wiring diagram for a cubic millimeter of brain tissue and the way all its neurons are firing.” But during the last seven years, a global team of more than 150 neuroscientists and…
