"Pleocytosis" Natural Recordings by Native Speakers
Pleocytosis is a medical term that refers to an increase in the number of white blood cells in the cerebrospinal fluid (CSF) in the brain and spinal cord. A normal CSF sample typically contains a certain number of white blood cells, but an elevated count can be a sign of a condition such as meningitis, encephalitis, or multiple sclerosis.
"This refers to a large or abundant quantity of something, implying that there is more than enough of the thing to meet a need or requirement. For example:"There's plenty of time left in the exam.""My bag has plenty of space for all your books."It implies an abundance or excess.
A plenum is a complete meeting of all the members of an organization, such as a company, association, or governing body, where all votes are typically taken. It is often used in contrast to a convention, which may include non-members or representatives.
Capable of exhibiting pleochroism, the property of a substance of appearing to have a different color when viewed from different directions.
Pleochroism is the property of a material (commonly minerals or crystals) that appears to change color when viewed from different directions. This is typically due to the way that different wavelengths of light are absorbed and transmitted by the material. When light is shone through a pleochroic material from one direction, it may appear one color, but when viewed from another direction, it may appear a different color.For example, a gemstone like tourmaline can exhibit pleochroism, showing a different color when viewed from different angles, such as green, blue, or red. This is because the arrangement of the atoms in the crystal structure affects how light interacts with the material.
Showing a phenomenon in which the color of a substance or material appears to shift or change when viewed from different angles, typically due to the way the microscopic crystals that make up the substance refract light.
Pleochromatism is a phenomenon in optics where the color of a gemstone or a crystal appears to change when it is turned at different angles under light.
Having many forms or characteristics, especially in relation to the form or development of an organism.
Having a tendency to change shape or form. (especially of cells in a tumor) synonyms: polymorphic, amorphous, shapeless, indeterminate. Antonyms: fixed, constant, unchanging.
Pleomorphism is a concept in various fields that refers to the capability of a structure, system, or concept to exist or manifest in multiple forms, shapes, or expressions. This can be seen in:1. Biology: Pleomorphism refers to the variability of cells in a diseased tissue, such as cancer cells, which may take on different shapes, sizes, and structures compared to healthy cells.2. Philosophy: In the philosophy of identity, pleomorphism is the idea that something can change its form or essence while remaining the same in substance.3. Software development: Pleomorphism refers to the capacity for an algorithm or data structure to adapt to different inputs, environments, or interpretations.4. Chemistry: Pleomorphism is the phenomenon of a substance existing in multiple crystalline forms or polymorphs, which can exhibit different physical and chemical properties.In general, pleomorphism suggests the existence of diversity, variability, or multiplicity in the structure, expression, or manifestation of a thing.
Pleomorphists are bacteria that exhibit a variable shape, often as a result of changing environmental conditions. The term is used in microbiology to describe the shape of individual bacteria, which can be influenced by factors such as temperature, pH, nutrient availability, and oxygen levels.In terms of etymology, the word "pleomorphism" comes from the Greek words "pleo," meaning "many," and "morph," meaning "form." This refers to the bacterial cells' ability to change shape, often without a significant reduction in cell size or disruption of cellular function.The observation of pleomorphism was first made by Antonie van Leeuwenhoek, a Dutch naturalist and microbiologist, in the 17th century. He used optical microscopy to study bacteria and noted that some species exhibited a range of shapes, from rod-shaped to spherical forms.Pleomorphists and their behavior have important implications for public health, medicine, and biotechnology. For instance, understanding the pleomorphism of bacteria in an infection can help improve treatment strategies.
The word "pleomorphic" (not "pleomorphous") refers to the quality of having many forms or shapes. It is used to describe something that exhibits a wide range of forms or a lack of a fixed shape.In biology, pleomorphism is used to describe cells, tissues, or organisms that can take on multiple forms or variations. For example, cancer cells often exhibit pleomorphism, meaning they can have varying sizes, shapes, and appearances.In a broader sense, pleomorphism can describe any situation or object that has multiple aspects, shapes, or appearances, rather than a fixed or consistent one.
Pleonasm is the use of more words than are necessary to express an idea or to make a point. It is a figure of speech that involves using redundant or unnecessary language, often to add emphasis or create a particular effect.
A figure of speech in which a word or phrase is repeated unnecessary because of its redundancy, often used for emphasis, rhythm, or effect.
