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.

Genetic testing before embryo transfer makes no difference to live birth rates

Blood samples used to understand repair and regeneration mechanisms of transplanted organs

Researchers at Wake Forest Baptist Medical Center have shown that gene expression analysis of blood samples taken from the recipients of transplanted kidneys can be used to better understand the mechanisms that promote repair and regeneration of the transplanted organs.

Study shows spillover effect of evidence-based opioid prescribing for major procedures

To curb the use of opioids after major elective operations and prevent these pain relievers from falling into the wrong hands, surgeons at the University of Michigan developed prescribing recommendations based on published medical evidence for one operation, gall bladder removal, and then discovered a spillover effect that led them to prescribe roughly 10,000 fewer pills for other major operations, according to study results appearing as an "article in press" on the website of the Journal of the American College of Surgeons ahead of print.

Melanoma could soon be detected using a blood test

West Australian researchers from Edith Cowan University have managed to develop a blood test that is capable of diagnosing melanomas before they can spread to other parts of the body. The study titled, “A diagnostic autoantibody signature for primary cutaneous melanoma,” was published in the latest issue of the journal Oncotarget.

New research lays foundation to create standards for RNA sequencing

The idea of testing blood or urine to find markers that help diagnose or treat disease holds great promise. But as technology has improved to allow researchers to examine tiny fragments of RNA, one major problem has led to limited success.

Researchers describe key role of enzyme in regulating immune response against Chagas disease parasite

In an article published recently in the journal Nature Communications, researchers affiliated with the University of São Paulo in Brazil describe the central role played by an enzyme called phosphatidylinositol 3-kinase gamma in regulating the immune response against Trypanosoma cruzi, the protozoan parasite that causes Chagas disease.

New study suggests testing urine and blood serum as better way to diagnose myeloma

When it comes to diagnosing a condition in which the plasma cells that normally make antibodies to protect us instead become cancerous, it may be better to look at the urine as well as the serum of our blood for answers, pathologists say.

Researchers develop simple blood test to predict likely spread of rare cancer

New QUT research has shed fresh light on how head and neck cancer spreads to other organs and researchers are developing a simple blood test to tell doctors which patients are at risk of spread long before conventional imaging can.

Researchers focus on mechanisms involved in development of non-alcoholic fatty liver disease

One of the lines of research of the UPV/EHU's Lipids & Liver group, which focusses on the mechanisms involved in the development and progression of non-alcoholic fatty liver disease, is achieving significant advances in a range of aspects; these include the identification of proteins that alter the metabolic pathways in the development and progression of liver disease, and even cancer, and the seeking of targets to enable the disease to be reversed.
