Fecal Zonulin Elevated in Crohn’s Disease and Smokers

Human zonulin is a protein that increases permeability in the epithelial layer of the small intestine by reversibly modulating the intercellular tight junctions. There is not sufficient information available about zonulin's participation in inflammatory bowel diseases (IBD). More...

High Thyroid Hormone Levels Associated with Arterial Disease

Atherosclerosis is the process of progressive thickening and hardening of the walls of arteries from fat deposits on their inner lining. Atherosclerosis progresses insidiously from a subclinical condition to the clinical onset of vascular events to death. More...

Autoimmune Disease Discovered Causes Kidney Failure

An insidious new autoimmune disease that causes kidney failure has been discovered. The condition causes a build-up of waste products in the blood and makes it difficult for kidneys to maintain adequate balance of fluid in the body. More...

Assay Identifies Patients Benefiting from Cancer Immunotherapies

Programmed cell death ligand 1 (PD-L1) has been detected in up to 50% of all human cancers, and has become a major focus of therapeutic and biomarker studies. More...

Potential Autoantigen Identified in Aggressive Kidney Disease

Fibrillary glomerulonephritis (FGN) is an aggressive kidney disease, and nearly half of patients become dependent on dialysis within several years of diagnosis. No unique clinical markers of FGN have been identified to help diagnose FGN, and current tests involve time-consuming analyses with light microscopy, immunofluorescence, and electron microscopy. More...

Disease Associations Discovered with Four IgG Subclasses

Immunoglobulin G4-related disease (IgG4-RD) is a relatively newly defined disease entity that refers to a group of immune-mediated disorders that have certain histopathologic, serologic, and clinical features in common. More...

Blood Test Can Effectively Rule Out Breast Cancer

Breast density is associated with reduced imaging resolution in the detection of breast cancer. Breast density is a radiologic phenomenon that is not discernable by palpation; it is a radiologist’s assessment. Imaging rays permeate dense breast tissue in a more opaque manner, thereby reducing image resolution. More...
