Early Detection of Aberrant Cell Fate and Repair Using Circulating Progenitor Cells in Heterotopic Ossification
Understanding heterotopic ossification and the promise of circulating progenitor cells Heterotopic ossification (HO) is the abnormal growth of bone in soft tissues, often following orthopedic injury or surgery. In patients who undergo plate osteosynthesis or other traumatic interventions, HO can limit range of motion, complicate rehabilitation, and raise the risk of future procedures. Recent research…

Life in fossil bones: clues from ancient blood biomarkers
Uncovering the hidden chemistry of fossils For generations, paleontologists have studied fossil bones to piece together how ancient beings lived. But bones don’t just preserve shape; they can harbor faint chemical whispers from long-ago blood. Advances in chemistry and imaging now let researchers read these tiny traces — biomarkers that survived burial and time —…

Increased pTau-181 Linked to Neurologic Long COVID: What It Means for Patients
Overview: pTau-181 and Neurological PASC Emerging research indicates that higher levels of phosphorylated tau-181 (pTau-181) may be associated with neurological manifestations of post-acute sequelae of SARS-CoV-2 infection, commonly called Neurological PASC (N-PASC). While long COVID symptoms vary, this line of investigation focuses on brain-related effects such as cognitive impairment, headaches, dizziness, and sensory changes. Understanding…

Link Between pTau-181 and Neurological Long COVID Gains Ground
New Clues on Neurological Long COVID Emerging research is strengthening the connection between elevated levels of phosphorylated Tau-181 (pTau-181) and the neurological manifestations observed in post-acute sequelae of SARS-CoV-2 infection, commonly referred to as Neurological PASC (N-PASC). The latest analyses suggest that higher pTau-181 in the blood or cerebrospinal fluid may reflect ongoing brain changes…

pTau-181 Elevations Linked to Neurological Long COVID: New Biomarker Insight
Overview: pTau-181 and Neurological Long COVID Emerging research suggests that elevated levels of phosphorylated tau-181 (pTau-181) in the blood may be associated with neurological symptoms experienced by some people after acute COVID-19. The findings add to a growing body of evidence that neurological post-acute sequelae of SARS-CoV-2 infection (Neurological PASC or N-PASC) could be linked…

Shingles Vaccine Slows Aging: Insights from Aging Clocks
New clues on aging and vaccines Emerging research suggests that getting a shingles vaccine may modestly slow certain molecular aging processes in older adults. The findings come from analyses that compare biological age indicators, measured in blood, between vaccinated and unvaccinated groups. While not a cure-all for aging, the study points to a potential, measurable…

Blood Test Could Detect Parkinson’s Before Tremors Appear
Early Signals: Could a Blood Test Detect Parkinson’s Sooner? Parkinson’s disease (PD) is widely recognized by its motor symptoms — tremors, stiffness, and slowed movement. But by the time those tremors appear, substantial neuronal loss has already occurred. Recent research suggests a simple, low-cost blood test might reveal biological changes years before classic symptoms emerge,…

Blood Test Aims to Detect Parkinson’s Before Tremors Start
New frontiers in Parkinson’s detection Researchers are exploring whether a simple blood test could reveal Parkinson’s disease long before characteristic tremors or movement difficulties appear. The idea is to identify faint biological signals—biomarkers in the blood—that indicate the brain is undergoing subtle changes associated with Parkinson’s. If successful, this approach could shift the disease from…

Blood Test Shows Promise for Detecting Parkinson’s Before Tremors
Early Biological Signals in the Blood Parkinson’s disease has long been diagnosed after motor symptoms like tremors and stiffness appear. New research, however, suggests that subtle biological changes in the blood long before these symptoms emerge could reveal an imminent diagnosis. If confirmed and scaled, a simple blood test could transform how clinicians approach this…

Finger-prick blood test shows promise for early Alzheimer’s diagnosis in international trial
Overview A major international research collaboration is testing whether a finger-prick blood test could help diagnose Alzheimer’s disease before symptoms appear. The trial focuses on measuring three specific proteins in blood, aiming to identify a reliable biomarker signature that signals the disease years before clinical diagnosis. The project is a joint effort led by LifeArc…
