"Opsonize" Natural Recordings by Native Speakers
To opsonize means to treat a particle, such as a bacterium or a virus, with antibodies or other molecules that mark it for destruction by phagocytic cells, such as neutrophils or macrophages. In other words, opsonization is the process of coating an invading pathogen with molecular signals that facilitate its recognition and engulfment by immune cells, leading to its elimination from the body. This process plays a crucial role in the host's defense against infection and is a key component of the immune response.
An opsiometer is an instrument used to measure the refractive index of a substance, particularly in optics and ophthalmology. It is a type of refractometer that determines the power and curvature of a surface by measuring the extent to which light is bent as it passes through the substance.
Opsonation is a biological process in which specific proteins, called opsonins, bind to pathogens, such as bacteria, viruses, or fungi, marking them for engulfment and destruction by immune cells, like phagocytes. In other words, opsonation is a way for the immune system to label and target pathogens for elimination, allowing the body to fight off infections more effectively. The prefix "opsos" comes from Greek, meaning "food" or "nourishment", highlighting the way opsonins provide a "food" for immune cells to feast on unwanted pathogens.
Opsonins are proteins or glycoproteins that mark pathogens, such as bacteria or viruses, for destruction by the immune system. They coat the surface of the pathogen, making it more recognizable by immune cells, which then engulf and destroy it.
To opt out of something means to deliberately choose not to be involved or participate in it. This can apply to contracts, agreements, subscription services, or other types of arrangements. For example, if you're asked to sign up for a company's email newsletter, you can opt out by declining the invitation or removing your name from the list.
Opt is a verb that means to choose or select the best or most suitable option from a available choices.
A Opteron is a brand of 32- or 64-bit processors made by AMD (Advanced Micro Devices). It is designed for server and workstations. Opteron processors are variants of the AMD64 architecture, a 64-bit extension of the x86 instruction set architecture. They have been widely used in servers, especially in data centers, to provide high-performance computing, floating-point processing, and multiprocessing capabilities.
