Biopsy News and Research

RSS

Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.

New platform helps non-experts use AI to analyze microscopy images

A new, freely available platform helps non-experts use artificial intelligence to analyze microscopy images. The platform has been developed at Åbo Akademi University in Finland and Instituto Gulbenkian de Ciência, Portugal, and will be of big help in research and diagnostics using modern day microscopes.

Study offers clues to clinical diagnosis of nephronophthisis in adults

Nephronophthisis (NPH) is a kidney disease affecting mainly children. Now, for the first time, researchers at Tokyo Medical and Dental University have studied a number of adults with NPH and highlighted clinical, genetic and pathological characteristics that could help in confirming this challenging diagnosis.

New blood-based test detects lymph node metastasis in individuals with high-risk T1 colorectal cancer

Scientists at City of Hope, a world-renowned independent research and treatment center for cancer and diabetes, have developed a novel, noninvasive liquid biopsy test for detecting lymph node metastasis in individuals with high-risk T1 colorectal carcinoma.

Microbiota-derived molecules do not change the entry or replication of SARS-CoV-2 in intestinal cells

A study conducted at the University of Campinas in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines.

Research could lead to a personalized approach for treating sickle cell disease

Sickle cell disease is the most prevalent inherited blood disorder in the world, affecting 70,000 to 100,000 Americans. However, it is considered an orphan disease, meaning it impacts less than 200,000 people nationally, and is therefore underrepresented in therapeutic research.
