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.
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.
A team of researchers at Tohoku University have developed a simple lab-based system for growing human muscle cells that are capable of vigorously contracting.
Scientists have observed for the very first time that insulin-producing cells in the pancreas are attacked by T lymphocytes during the evolution of Type 1 Diabetes.
Joint study will assess clinical value of comprehensive genomic profiling (CGP) on cancer therapy options in patients with advanced disease
Preclinical models that recapitulate aspects of human airway disease are essential for the advancement of novel therapeutics and vaccines.
In the war against cancer, the first step towards treating them is an accurate diagnosis of the problem. A technique that helps plan a better course of treatment is a biopsy.
Doctors monitor kidney transplant recipients for signs of rejection in several ways, including biopsy.
Depixus®, a biotechnology company, today announces it has raised EUR 30.6 million in an oversubscribed Series A financing.
Tumors are heterogeneous, which means that different parts of the same tumor can be genetically distinct. This phenomenon, known as intratumor heterogeneity, is steadily gaining in significance within the field of cancer research.
Scientists recently created a technique to accurately and quickly correct genetic alterations in the cultivated patient cells.
Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide, affecting more than 40 % of the population and is one of the causes of digestive symptoms, such as epigastric discomfort, heaviness or bloating of the stomach, or of other more serious diseases, such as the development of gastric and duodenal ulcers, gastric lymphoma or gastric cancer.
