Isodicentric 15, also called marker chromosome 15 syndrome, [2] idic(15), partial tetrasomy 15q, or inverted duplication 15 (inv dup 15), is a chromosome abnormality in which a child is born with extra genetic material from chromosome 15.
Interstitial atoms (blue) occupy some of the spaces within a lattice of larger atoms (red) In materials science, an interstitial defect is a type of point crystallographic defect where an atom of the same or of a different type, occupies an interstitial site in the crystal structure.
The same is true in a unit cell; no matter how the atoms are arranged, there will be interstitial sites present between the atoms. These sites or holes can be filled with other atoms (interstitial defect). The picture with packed circles is only a 2D representation. In a crystal lattice, the atoms (spheres) would be packed in a 3D arrangement ...
The term INAH (interstitial nuclei of the anterior hypothalamus), first proposed in 1989 by a group of the University of California at Los Angeles, refers to 4 previously undescribed cell groups of the preoptic-anterior hypothalamic area (PO-AHA) of the human brain, which is a structure that influences gonadotropin secretion, maternal behavior, and sexual behavior in several mammalian species.
It contains the interstitial nucleus of Cajal, responsible for oculomotor control, head posture, and vertical eye movement. [ 2 ] The MLF interconnects interneurons of each abducens nucleus with motor neurons of the contralateral oculomotor nucleus ; thus, the MLF mediates coordination of horizontal (side to side) eye movements, ensuring the ...
Interstitial lung disease affects gas flow in the alveoli The alveoli Micrograph of usual interstitial pneumonia (UIP). UIP is the most common pattern of idiopathic interstitial pneumonia (a type of interstitial lung disease) and usually represents idiopathic pulmonary fibrosis. H&E stain. Autopsy specimen.
The brain parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells. [7] It is also known to contain collagen proteins. [ 8 ] Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.
Less than 20% of individuals with an imprinting defect are found to have a very small deletion in the PWS imprinting centre region, located at the 5′ end of the SNRPN gene. [ 4 ] AS is a severe debilitating neurodevelopmental disorder characterized by mental retardation, speech impairment, seizures, motor dysfunction, and a high prevalence of ...
