Relationships Between Brain Glucose Metabolism Patterns and Impaired Glycemic Status: A Systematic Review of FDG‐PET Studies With a Focus on Alzheimer's Disease

Human Brain Mapping, Volume 46, Issue 4, March 2025.
Insulin resistance can lead to neuronal damage and cerebral hypometabolism through different mechanisms including mitochondrial dysfunction, impairment of cerebral blood vessel function. In addition, insulin resistance is linked to amyloid and tau accumulation and neuroinflammation, the key mechanisms involved in Alzheimer disease and neuronal damage ...

The Common Alzheimer's Disease Research Ontology (CADRO) for biomarker categorization

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 11, Issue 1, January-March 2025.
Abstract Biomarkers are vital to Alzheimer's disease (AD) drug development and clinical trials, and will have an increasing role in clinical care. In this narrative review, we demonstrate the use of the National Institutes on Aging/Alzheimer's Association (NIA/AA) Common Alzheimer's Disease Research Ontology (CADRO) system for the categorization of ...

Tumor‐Associated Carbohydrate Antigen 19–9 (CA 19–9), a Promising Target for Antibody‐Based Detection, Diagnosis, and Immunotherapy of Cancer

ChemMedChem, Volume 19, Issue 24, December 16, 2024.
Carbohydrate antigen 19–9 (CA 19–9), also known as sialyl Lewis A, is a tetrasaccharide overexpressed on a wide range of cancerous cells, most prominently pancreatic ductal adenocarcinoma. The review discusses the synthesis of CA 19–9, elicitation of antibodies through vaccination, development of anti‐CA 19–9 monoclonal antibodies, and their ...
