Plasma Serglycin Levels Evaluated for Diabetic Retinopathy Diagnosis

Diabetic retinopathy (DR), a microvascular complication caused by chronic diabetes mellitus (DM), is a significant threat to vision in adults, which may even lead to blindness and retinal detachment. The clinical symptoms of DR include fibrosis, capillary obstruction, neovascularization, and increased vascular permeability. More...

Single-Cell Transcriptome Links Gut Development, Pediatric Crohn's Disease

Development of the human intestine is a highly complex process that requires synergy between a wide range of cell types. Importantly, environmentally triggered alterations in early development have been implicated in a range of immune-mediated pathologies, including inflammatory bowel diseases (IBD). More...

Rare Genetic Variants Can Contribute to Ischemic Heart Failure

Heart failure affects about 40 million people globally, and most cases are due to ischemic heart disease, hypertension, or cardiomyopathies. Cardiomyopathies have been traced to rare variants in genes that encode sarcomere or cytoskeletal proteins, channels, or desmosomes, while genome-wide association studies have underscored common variants linked to heart failure. More...

Osteopontin Linked to Progressive Lung Scarring in Scleroderma Patients

Systemic sclerosis (SSc) is an autoimmune disease characterized by a distinct pathogenic triad of microvascular damage, dysregulation of innate and adaptive immunity, and fibrosis involving skin and many internal organs, such as the heart, kidney, and lungs. More...

Next-Generation Sequencing Detects Residual Disease in Acute Lymphoblastic Leukemia

The use of next-generation sequencing (NGS) to detect residual disease in acute lymphoblastic leukemia (ALL) patients after treatment can better gauge their risk of relapse and overall survival than multiparameter flow cytometry. More...

Distinct Mutation Patterns Identified in Appendiceal Cancer

The incidence of appendiceal cancer (AC) is rising, particularly among individuals younger than 50 years (early-onset AC), with unexplained etiologies. The unique spectrum of somatic cancer gene variations among patients with early-onset AC is largely undetermined. More...
