Liquid Biopsy Predicts Colon Cancer Relapse Months Earlier

Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine). Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and fatigue. More...

Cell-Free DNA Detects Heart Allograft Acute Rejection

After heart transplantation, Endomyocardial biopsy (EMBx) is used to monitor for acute rejection (AR). Unfortunately, EMBx is invasive and its conventional histologic interpretation has limitations. More...

Proinflammatory T Cell Polarization Investigated in Early Knee Osteoarthritis

In osteoarthritis (OA), the cartilage in the knee joint gradually wears away. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone, and produce painful bone spurs. Osteoarthritis develops slowly and the pain it causes worsens over time. More...

Alzheimer's Progression Tracked with Blood Biomarkers

Alzheimer disease (AD) is a neurodegenerative disorder characterized by the accumulation of amyloid-β (Aβ) plaques and neurofibrillary tangles of hyperphosphorylated tau in the brain. These neuropathological changes are believed to take part in a cascade of events that result in a characteristic neurodegeneration pattern followed by progressive cognitive impairment. More...

Mismatch Repair/Microsatellite Instability Evaluated Using Cytology Effusion Specimens

DNA mismatch repair (MMR) status is routinely assessed in colorectal and endometrial carcinoma as a method of cancer prevention, surveillance in patients with Lynch syndrome and their families, and for prognostic, predictive, and therapeutic implications. More...

Metastatic Gastric Cancer Outcomes Informed by Single-Cell Transcriptome Profiles

Peritoneal Carcinomatosis (PC) is a late stage manifestation of several gastrointestinal malignancies including appendiceal, colorectal, and gastric cancer. In PC, tumors metastasize to and deposit on the peritoneal surface and often leave patients with only palliative treatment options. More...

Alzheimer's Disease Subtypes Proposed from Brain Gene Expression Profiles

Alzheimer’s disease (AD) is the most common form of dementia in the elderly, estimated to affect more than 5.8 million individuals in the USA and more than 50 million worldwide, with almost half of individuals aged over 75 years. More...
