Genetic Variations Increase Heart Attack Risk for Statin Patients

Coronary heart disease (CHD) is a leading cause of death globally. Although therapy with HMG-CoA reductase inhibitors (statins) decreases circulating levels of low-density lipoprotein cholesterol (LDL-C) and the incidence of CHD, additional events occur despite statin therapy in some individuals.

Genetic Predisposition Validated in Medulloblastoma

Medulloblastoma is a rare malignant tumor of the brain and occurs predominantly in children and is associated with rare hereditary cancer predisposition syndromes. It is believed that in many cases hereditary gene defects trigger the development of this malignant disease. More...

Specific Biomarker Discovered for Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune disorder that occurs when the immune system mistakenly attacks the body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of the joints, causing painful swelling that can eventually result in bone erosion and joint deformity. More...

Image: A histopathology of classic Mycosis fungoides. This skin biopsy specimen demonstrates an atypical lymphocytic infiltrate going up into the epidermis (epidermotropism) in the absence of epidermal edema (spongiosis). The collection of atypical lymphocytes surrounding a Langerhans cell is a Pautrier microabcess, the hallmark of classic MF (Photo courtesy of the University of Pennsylvania).

Tool Predicts Deadly Form of Mycosis Fungoides

Mycosis fungoides (MF), the most common cutaneous T cell lymphoma (CTCL) is a malignancy of skin-tropic memory T cells. Most MF cases present as early stage (stage I A/B, limited to the skin), and these patients typically have a chronic, indolent clinical course. More...

Factors Affecting Plasma DNA Analysis Evaluated

There is vast potential in precision-medicine methods of both detecting and monitoring disease by looking for indications of cancer mutations in cell-free DNA (cfDNA), circulating in the blood. However, there are many factors that can significantly alter these samples as they are collected and analyzed. More...

Near-Patient Hepatitis C Assay Validated

Chronic infection with hepatitis C virus (HCV) is a major public health problem, estimated to infect 1.0% of the world’s population (71 million people) and to be responsible for 400, 000 annual deaths as a result of cirrhosis and liver cancer. More...

Molecular Subtype Identified for CRCs Metastasized to Liver

Metastases are the leading cause of cancer-related deaths and frequently are widely disseminated, which has led to the prevailing view that metastases are always widespread. More...
