Microscopy, Scanning Probe
|
D020527 |
[Scanning microscopy in which a very sharp probe is employed in close proximity to a surface, exploiting a particular surface-related property. When this property is local topography, the method is atomic force microscopy (MICROSCOPY, ATOMIC FORCE), and when it is local conductivity, the method is scanning tunneling microscopy (MICROSCOPY, SCANNING TUNNELING).

Microscopy, Scanning Tunneling
|
D016252 |
[A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.

Microscopy, Ultraviolet
|
D008860 |
[Microscopy in which the image is formed by ultraviolet radiation and is displayed and recorded by means of photographic film.

Microscopy, Video
|
D018715 |
[Microscopy in which television cameras are used to brighten magnified images that are otherwise too dark to be seen with the naked eye. It is used frequently in TELEPATHOLOGY.

Microsomes
|
D008861 |
[Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)

Microsomes, Liver
|
D008862 |
[Closed vesicles of fragmented endoplasmic reticulum created when liver cells or tissue are disrupted by homogenization. They may be smooth or rough.

Microspectrophotometry
|
D015591 |
[Analytical technique for studying substances present at enzyme concentrations in single cells, in situ, by measuring light absorption. Light from a tungsten strip lamp or xenon arc dispersed by a grating monochromator illuminates the optical system of a microscope. The absorbance of light is measured (in nanometers) by comparing the difference between the image of the sample and a reference image.

Microspheres
|
D008863 |
[Small uniformly-sized spherical particles, of micrometer dimensions, frequently labeled with radioisotopes or various reagents acting as tags or markers.

|
Microsporea
|
D016815 |
[A class of parasitic FUNGI. Characteristics include spores that are spherical, oval, or tubular in shape and sporoplasm which is uninuclear or binuclear. Microsporea is a heterotypic synonym for Microsporidia.

|
Microsporida
|
D016816 |
[An order of parasitic FUNGI found mostly in ARTHROPODS; FISHES; and in some VERTEBRATES including humans. It comprises two suborders: Pansporoblastina and APANSPOROBLASTINA.

|
Microsporidia
|
D016814 |
[A phylum of fungi comprising minute intracellular PARASITES with FUNGAL SPORES of unicellular origin. It has two classes: Rudimicrosporea and MICROSPOREA.

Microsporidia, Unclassified
|
D021861 |
[This is not an official taxonomic designation, but is often used as a general term for members of the phylum MICROSPORIDIA or as a placeholder for unclassified species.
, Includes newly defined organisms as well as some that will never be classified to the genus and/or species level because of loss of the specimen or other information.

Microsporidiosis
|
D016881 |
[Infections with FUNGI of the phylum MICROSPORIDIA.

|
Microsporum
|
D008864 |
[A mitosporic Oxygenales fungal genus causing various diseases of the skin and hair. The species Microsporum canis produces TINEA CAPITIS and tinea corporis, which usually are acquired from domestic cats and dogs. Teleomorphs includes Arthroderma (Nannizzia).

Microstomia
|
D008865 |
[A congenital defect in which the mouth is unusually small. (Dorland, 27th ed)

Microsurgery
|
D008866 |
[The performance of surgical procedures with the aid of a microscope.

|
Microtechnology
|
D055616 |
[Manufacturing technology for making microscopic devices in the micrometer range (typically 1-100 micrometers), such as integrated circuits or MEMS. The process usually involves replication and parallel fabrication of hundreds or millions of identical structures using various thin film deposition techniques and carried out in environmentally-controlled clean rooms.

|
Microtomy
|
D008867 |
[The technique of using a microtome to cut thin or ultrathin sections of tissues embedded in a supporting substance. The microtome is an instrument that hold a steel, glass or diamond knife in clamps at an angle to the blocks of prepared tissues, which it cuts in sections of equal thickness.
