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.
Irregularities in the body's genetic coding to make proteins are linked to cancerous tumors. But most genetic material contains elements whose function isn't clear.
Muscles that ache after a hard workout usually don't hurt for long, thanks to stem cells that rush to the injured site along "collagen highways" within the muscle and repair the damaged tissue.
Multiple myeloma is a rare blood cancer caused by the uncontrolled multiplication of abnormal plasma cells.
An international team led by researchers at Baylor College of Medicine with the National Institutes of Health Extracellular RNA Communication Consortium and the Bogdan Mateescu laboratory at the ETH Zürich and University of Zürich has developed a new powerful resource to study extracellular RNA (exRNA), a novel form of cell-to-cell communication.
According to a study conducted by UCLA, patients with advanced melanoma responded differently to PD-1 checkpoint blockade immunotherapy depending on a variety of variables, including whether or not they had previously received CTLA-4 blockade, another type of immunotherapy.
Proteomics is the study and analysis of proteins in a biological system, including their structures, functions, associations, and alterations.
Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis. A relative, Yersinia pseudotuberculosis, causes gastrointestinal illness and is less deadly but naturally infects both mice and humans, making it a useful model for studying its interactions with the immune system.
A tumor's necrotic core contains factors that appear to promote metastasis, or the seeding of tumors cells throughout the body, according to a new study in rats by researchers at Fred Hutchinson Cancer Center.
Jon Jacobs, a biochemist, has examined the blood of people suffering from diseases including Ebola, cancer, TB, hepatitis, diabetes, Lyme disease, brain damage, and influenza.
Researchers at the University of Sussex are using Artificial Intelligence (AI) technology to analyze different types of cancer cells to understand different gene dependencies, and to identify genes that are critical to a cell's survival.
Researchers at Johns Hopkins Medicine say they have created a laboratory-grown three-dimensional "organoid" model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point where the digestive system's food tube meets the stomach.
The development of “mini eyes” by researchers at the UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) has made it possible to study and comprehend the onset of blindness in the rare genetic disease known as Usher syndrome more.
Recent research discovered that bowel tumors can be classified into six clinically relevant subcategories based on patterns of gene interactions seen within tumor cells. The study was published in eLife.
The human immune system is notably adept at evading tumor cells, which construct physical barriers, adopt masks, and restrain the immune system with molecular ploys.
Heart damage is prevalent in COVID-19 patients, leading many to doubt how the virus impacts the heart.
A multidisciplinary group of researchers at the University of California San Diego School of Medicine have advanced investigations into the genetic causes of NAFLD in children.
The cancer type cholangiocarcinoma, often known as bile duct cancer, is characterized by a high fatality rate.
Patients diagnosed with a type of brain tumor survived for longer when they were treated aggressively with surgery, radiation and chemotherapy.
This scientific breakthrough, which was published in the science journal Theranostics, might pave the way for cancer patients to prevent developing metastases.
A study published today in Nature Communications unveils a new platform for discovering cellular signatures of disease that integrates robotic systems for studying patient cells with artificial intelligence methods for image analysis.
