RDGuru: A Conversational Intelligent Agent for Rare Diseases

Intelligent Conversational Agent for Rare Diseases—RDGuru: Cutting-edge Technology Powers a New Revolution in Clinical Diagnosis Academic Background and Research Motivation Rare Diseases (RD) refer to disease categories that affect fewer than 6.5 to 10 individuals per 10,000 population. Their individual rarity, complex clinical features, and divers...

Aging Promotes Reactivation of the Barr Body at Distal Chromosome Regions

1. Academic Background: The Mysterious Link between X Chromosome Inactivation and Aging In mammals, females possess two X chromosomes while males have only one. To maintain gene dosage balance between the sexes, females undergo a process called X chromosome inactivation (XCI) early in development, in which one of the two X chromosomes is randomly s...

Research Background and Scientific Questions Epigenetics, especially DNA methylation, has become a cutting-edge frontier in aging mechanism research in rece...

Targeting the Chromatin Remodeler BAZ2B Mitigates Hepatic Senescence and MASH Fibrosis

1. Research Background and Significance With global population aging on the rise, the incidence of metabolic dysfunction-associated steatohepatitis (MASH, also known as NASH) and related chronic liver diseases such as hepatic fibrosis is increasing year by year. These disorders have become a major focus and challenge in basic and clinical hepatolog...

Role of Recurrent Somatic Mutation and Progerin Expression in Early Vascular Aging of Chronic Kidney Disease

1. Academic Background and Research Rationale Chronic Kidney Disease (CKD) is a global public health challenge. Epidemiological data indicate that CKD affects approximately 10–12% of the world’s population, acting as a major driver of cardiovascular disease (CVD) mortality worldwide. CKD patients often display “Early Vascular Aging” (EVA) phenomena...
