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.

Study shows SARS-CoV-2 direct heart muscle cell infection, cell death, loss of contractility

In the study, published on the pre-print journal bioRxiv, the researchers revealed that SARS-CoV-2-infected EHTs manifested the typical characteristics of myocarditis or heart inflammation. These include the stimulation of immune cells, heart cell death, and decreased contractile force generation.

Study identifies key clinical features of chronic nonbacterial osteomyelitis

New research presented at ACR Convergence, the American College of Rheumatology's annual meeting, identified key clinical features of chronic nonbacterial osteomyelitis (CNO), which leads to an important step toward the development of much-needed classification criteria for a disease that affects children and young adults worldwide.

Researchers develop novel chemo-immunotherapy agent to treat pancreatic tumors

Pancreatic cancer is highly lethal: according to the National Cancer Institute, only about 10 percent of patients remain alive five years after diagnosis.

Unrelated mutations can lead to false-positive results in men with advanced prostate cancer

Unrelated mutations, when present in the blood, can lead to false-positive results in men with advanced prostate cancer who are undergoing liquid biopsies.

Experts release new guidance for endoscopists on how to assess colorectal lesions

Early identification and removal of cancerous colorectal polyps is critical to preventing the progression of colorectal cancer and improving survival rates.

Improving sensitivity of liquid biopsy using 'loosely stacked' detection layers

By detecting DNA fragments in body fluids like urine, some types of cancer can already be traced in an early stage. But in order to capture them, detection sensitivity has to be improved.

Tumor suppressor gene represses 'jumping genes'

About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or "jumping genes," from hopping around the human genome.

Multimodal mapping of immune landscape in pancreatic cancer could guide personalized therapies

Pancreatic cancer has remained resistant to immunotherapies that are revolutionizing the treatment of many types of cancer.

Researchers create AI system that matches tumors to best drug combinations

Only 4 percent of all cancer therapeutic drugs under development earn final approval by the U.S. Food and Drug Administration (FDA).

Tumor DNA in spinal fluid can help track children with aggressive brain tumors

For many cancers, doctors are increasingly looking to the DNA that solid tumors shed into the blood stream to help with diagnosis and monitoring. But brain cancer has been a different story thanks to the natural blockade created by the blood-brain barrier.

Scientists develop a way to accurately detect and monitor common pediatric brain cancer

A team of scientists at Texas A&M University, Baylor College of Medicine and Texas Children's Hospital have developed a way to more accurately both detect and monitor a common type of pediatric brain cancer, setting the stage for giving clinicians a real-time view into how the cancer responds to treatment.

Scientists use gold nanorod scattering to identify changes in macrophages

Every biological system is naturally equipped with a defense mechanism to protect against abnormal changes caused by either local, environmental, or biochemical alteration. White blood cells play the role of such a 'soldier' in our immune response.

NMR Metabolomics as Novel Screening Tool for New-borns (For Research Only)

In this interview, Oscar Millet, group leader of the Precision Medicine and Metabolism group of the CIC bioGUNE, talked to News Medical about his research into the use of nuclear magnetic resonance spectroscopy (NMR) metabolomic analysis as a clinical screening tool. His team has used NMR to screen urine samples form new-borns for congenital metabolic disorders.

Start-up receives NIH grant to accelerate development of contrast agent to detect liver fibrosis

Inlighta Biosciences, LLC, a start-up company led by Jenny Yang, Regents' Professor of Chemistry at Georgia State University, has been awarded a National Institute of Health grant to accelerate development of a magnetic resonance imaging contrast agent to detect liver fibrosis, formation of scar tissue in the liver caused by alcoholic and non-alcoholic fatty liver disease.

New saliva tests can enable early detection and diagnosis of COVID-19, head & neck cancer

Summit Biolabs, Inc., an early-stage molecular diagnostics company specializing in saliva-based testing for COVID-19 and head & neck cancer, and the Colorado Center for Personalized Medicine (CCPM) at the University of Colorado Anschutz Medical Campus announced today a broad strategic collaboration involving research, development and commercialization of saliva liquid-biopsy tests for early cancer detection and diagnosis of COVID-19 and other viral contagions.
