Histologic specimen being placed on the stage of an optical microscope Human lung tissue stained with hematoxylin and eosin as seen under a microscope. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
The second method of histology processing is called frozen section processing. This is a highly technical scientific method performed by a trained histoscientist. In this method, the tissue is frozen and sliced thinly using a microtome mounted in a below-freezing refrigeration device called the cryostat. The thin frozen sections are mounted on ...
Stereology is a method that utilizes random, systematic sampling to provide unbiased and quantitative data. It is an important and efficient tool in many applications of microscopy (such as petrography , materials science , and biosciences including histology , bone and neuroanatomy ).
Gross examination of a kidney (right of image) with a renal oncocytoma (left of image).. Gross processing, "grossing" or "gross pathology" is the process by which pathology specimens undergo examination with the bare eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination.
The use of tissue microarrays in combination with immunohistochemistry has been a preferred method to study and validate cancer biomarkers in various defined cancer patient cohorts. The possibility to assemble a large number of representative cancer samples from a defined patient cohort that also has a corresponding clinical database, provides ...
Microscopic view of a histologic specimen of human lung tissue stained with hematoxylin and eosin. Automated tissue image analysis or histopathology image analysis ( HIMA ) is a process by which computer-controlled automatic test equipment is used to evaluate tissue samples, using computations to derive quantitative measurements from an image ...
Method Utility Branches Distance sampling: Used for estimating the density and/or abundance of populations: Ecology: Mark and recapture: Used to estimate an animal population's size where it is impractical to count every individual. [17] Ecology
In medicine, sampling is gathering of matter from the body to aid in the process of a medical diagnosis and/or evaluation of an indication for treatment, further medical tests or other procedures. In this sense, the sample is the gathered matter, and the sampling tool or sampler is the person or material to collect the sample.
