Aging-induced tRNAglu-derived fragment impairs glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization

Aging-induced trnaGlu-derived fragments disrupt glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization Academic Background Mitochondrial cristae are inward protrusions of the inner mitochondrial membrane that undergo significant morphological changes during aging. However, the molecular mechanisms leading to th...

Imaging Brain Glucose Metabolism In Vivo Reveals Propionate as a Major Anaplerotic Substrate in Pyruvate Dehydrogenase Deficiency

Imaging Study of Brain Glucose Metabolism in Patients with Pyruvate Dehydrogenase Deficiency Background In modern mitochondrial medicine, evaluating the spectrum of brain diseases has been a limiting challenge. This limitation hinders our ability to understand the mechanisms behind the imaging phenotypes of the brains of mitochondrial disease patie...

Neuronal AMPK Regulates Microglial Lipid Droplet Accumulation in Tauopathy Brain

Accumulation of Lipid Droplets in Microglia is Regulated by Neuronal AMPK Background and Research Question Alzheimer’s Disease (AD) is a common type of dementia characterized by neurofibrillary tangles and β-amyloid plaques. However, beyond these classical pathologies, changes in lipid metabolism are increasingly recognized as closely associated wi...

White Matter Microstructural Changes Using Ultra-Strong Diffusion Gradient MRI in Adult-Onset Idiopathic Focal Cervical Dystonia

Study Report on White Matter Microstructure Changes in Adult-Onset Idiopathic Focal Cervical Dystonia Patients Scientists are dedicated to studying Adult-Onset Idiopathic Focal Cervical Dystonia (AOIFCD), the most common type of idiopathic dystonia in adults. This condition primarily manifests as abnormal neck muscle postures, often accompanied by ...

Prehospital Lactate Levels Obtained in the Ambulance and Prediction of 2-Day In-Hospital Mortality in Patients with Traumatic Brain Injury

Research Report Background Overview Traumatic Brain Injury (TBI) is one of the leading causes of permanent disability and death worldwide. These disorders are dynamic and evolving, involving progressive brain injury and pathophysiological changes accompanied by multi-system damage. The severity of TBI is typically assessed using the Glasgow Coma Sc...

Long-term Dementia Risk in Parkinson Disease

Study on the Long-Term Risk of Dementia in Parkinson’s Disease Background Parkinson’s Disease (PD) is a common neurodegenerative disorder primarily characterized by motor dysfunction. However, cognitive decline and Parkinson’s disease dementia (PDD) are also significant non-motor symptoms of PD. Although dementia occurs in approximately 80% of PD p...
