  • Breakthrough approach for diagnosing TB could significantly improve detection

    Breakthrough approach for diagnosing TB could significantly improve detection

    A new strategy for tuberculosis (TB) screening, proposed by a team of researchers led by Queen Mary University of London, provides a solution to problems with current TB screening, which does not always accurately detect disease. Simultaneously screening for both active and dormant TB infection could save lives, curtail infection rates, and rewrite the story of the continued spread of this disease. Researchers hope that this new approach will inform guidance from global health organisations…

  • Age-related genetic changes in the blood associated with poor cancer prognosis

    Age-related genetic changes in the blood associated with poor cancer prognosis

    Researchers from the Francis Crick Institute, UCL, Gustave Roussy and Memorial Sloan Kettering Cancer Center (MSK), have discovered that expansion of mutant blood cells, a phenomenon linked to ageing, can be found in cancerous tumours, and this is associated with worse outcomes for patients.

    Understanding the biological interface of age-related genetic changes and diseases of ageing, such as cancer and cardiovascular disease, is important to develop preventative therapies for a growing…

  • Vision loss fear may keep some from having cataract surgery

    Vision loss fear may keep some from having cataract surgery

    Fear of vision loss may deter some patients from undergoing necessary cataract surgery, according to a newly published study. Cataracts are the leading cause of reversible blindness, and surgery remains the only effective treatment.

    The study, recently published in The Journal of Clinical Ophthalmology, highlights the trust patients place in their physicians and the critical role of doctor-patient communication in making medical decisions.

    The research was led by Lisa Kelly, MD, a Taylor…

  • Clinical trials to test vaccine against Alzheimer’s-promoting tau protein

    Clinical trials to test vaccine against Alzheimer’s-promoting tau protein

    University of New Mexico Health Sciences researchers hope to launch human clinical trials in their quest for a vaccine to prevent the buildup of pathological tau — a protein in the brain associated with Alzheimer’s dementia.

    In a new paper published in Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association, a team led by Kiran Bhaskar, PhD, professor in the Department of Molecular Genetics & Microbiology in the UNM School of Medicine, found that the experimental vaccine…

    B cells found to be crucial for long-term vaccine protection, new study shows

    Researchers at the University of Colorado Anschutz Medical Campus have uncovered a critical, previously underappreciated role for B cells in vaccine protection. Best known for producing antibodies, B cells also guide other immune cells, specifically CD8 T cells, teaching them how to mount lasting defenses after vaccination.

    The study was recently published in The Journal of Clinical Investigation.

    “Think of CD8 T cells as rookie firefighters,” said lead author Jared Klarquist, PhD, assistant…

  • ATP prevents harmful aggregation of proteins associated with Parkinson’s and ALS

    ATP prevents harmful aggregation of proteins associated with Parkinson’s and ALS

    Neurodegenerative disease like Alzheimer’s, Parkinson’s, and ALS (amyotrophic lateral sclerosis) are debilitating conditions that affect millions of people worldwide every year. These pathologies are notoriously difficult to prevent or effectively treat due to a complex interplay of genetics, lifestyle, co-infection, and many other factors impacting everything from diagnosis to treatment.

    While a comprehensive cure-all to these neurological conditions is unlikely, scientists are making…

  • The antibiotic that takes the bite out of Lyme

    The antibiotic that takes the bite out of Lyme

    Lyme disease, a disease transmitted when deer ticks feed on infected animals like deer and rodents, and then bite humans, impacts nearly half a million individuals in the U.S. annually. Even in acute cases, Lyme can be devastating; but early treatment with antibiotics can prevent chronic symptoms like heart and neurological problems and arthritis from developing.

    Scientists from Northwestern University have identified that piperacillin, an antibiotic in the same class as penicillin,…

  • Post-treatment Lyme disease syndrome may be driven by remnants of infection

    Post-treatment Lyme disease syndrome may be driven by remnants of infection

    Symptoms that persist long after Lyme disease is treated are not uncommon — a 2022 study found that 14% of patients who were diagnosed and treated early with antibiotic therapy would still develop Post Treatment Lyme Disease (PTLD). Yet doctors puzzle over the condition’s causes and how to help their patients through symptoms ranging from severe fatigue and cognitive challenges to body pain and arthritis.

    Now, Northwestern University scientists believe they know what causes the treated…

  • Researchers identify pathway responsible for calciphylaxis, a rare and serious condition

    Researchers identify pathway responsible for calciphylaxis, a rare and serious condition

    The global burden of chronic kidney disease (CKD) is rising, with more than 800 million people affected worldwide. Vascular diseases in patients with CKD are unique and grouped as uremic vascular diseases. One of them, calciphylaxis, typically affects patients with end-stage, advanced kidney disease. It is a condition characterized by severe, painful and non-healing skin ulcers with no known cure.

    For the first time, researchers from Boston University Chobanian & Avedisian School of Medicine…

    FRESH bioprinting brings vascularized tissue one step closer

    Collagen is well-known as an important component of our skin, but its impact is much greater, as it is the most abundant protein in the body, providing structure and support to nearly all tissues and organs. Using their novel Freeform Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting technique, which allows for the printing of soft living cells and tissues, Carnegie Mellon’s Feinberg lab has built a first-of-its-kind microphysiologic system, or tissue model, entirely out of…
