Endoscopic Retrograde Cholangiopancreatography (ERCP) Procedure

Endoscopic retrograde cholangiopancreatography (ERCP) is a medical technique that is used primarily to investigate and treat pathologies involving the biliary tree and pancreatic ducts. Indications which could warrant need for ERCP include gallstones, tumors, defective sphincters, sclerosis of ducts and pseudocysts, which are accumulations of fluid and tissue components. ERCP has been traditionally used for […]

Why Cryo-EM is Gaining Popularity in Structural Biology

By Shelley Farrar, MSc, BSc Cryo-electron microscopy, also known as Cryo-EM, is a technique for visualizing macromolecular structures which has been developed over the last two decades. It is a form of transmission electron microscopy which permits samples to be studied at cryogenic temperatures. Biological structures such as ribosomes and mitochondria from pathogens, ion channels […]

Superparamagnetism in Biomedicine

Superparamagnetism occurs in ferromagnetic nanoparticles, where in the absence of a magnetic field their total average magnetism in any direction (magnetization) appears to be zero. Once in the presence of an external magnetic field they become magnetized, with their magnetic moments aligning with the field. Nanoparticles made from iron oxide are among the most studied […]

MALDI Mass Spectrometry in Biomedicine

Matrix-assisted laser desorption ionization (MALDI) mass spectrometry enables rapid profiling of various biomolecules from both tissues and biofluids. Rost9 | Shutterstock Although MALDI was originally used for the analysis of peptides and proteins, it now plays an important role in biomarker discovery, genotyping, identification of microorganisms, lipidomic analysis, and metabolomics. Improvements in the selection of […]
