chromosome inversion definition: chromosomal change in which a segment has been rotated by 180 degrees relative to the regions on either side and reinserted.
Chromosome Inversion definition: An aberration in which a chromosomal segment is deleted and reinserted in the same place but turned 180 degrees from its original orientation, so that the gene sequence for the segment is reversed with respect to that of the rest of the chromosome.
Chromosomal Inversion definition: A type of chromosome rearrangement in which a segment has been turned through 180 degrees (inverted), and inserted back into its original location on the chromosome.
Situs Inversus definition: A congenital abnormality in which organs in the THORAX and the ABDOMEN are opposite to their normal positions (situs solitus) due to lateral transposition. Normally the STOMACH and SPLEEN are on the left, LIVER on the right, the three-lobed right lung is on the right, and the two-lobed left lung on the left. Situs inversus has a familial pattern and has been associated with a number of genes related to microtubule-associated proteins.
heterotaxia syndrome definition: A laterization defect marked by asymmetric position of visceral organs usually occurring as a component of a wide variety of abnormalities. Transposition may be complete, with the heart, lungs and all abdominal organs reversed, or incomplete, manifesting itself as a simple reversal of the stomach or spleen. Associated malformations are variable and may include tetralogy of Fallot, transposition of great vessels, pulmonary valve stenosis, ventricular and atrial septal defects, asplenia-polysplenia. and other defects.
Factor For Inversion Stimulation Protein definition: A highly abundant DNA binding protein whose expression is strongly correlated with the growth phase of bacteria. The protein plays a role in regulating DNA topology and activation of RIBOSOMAL RNA transcription. It was originally identified as a factor required for inversion stimulation by the Hin recombinase of SALMONELLA and Gin site-specific recombinase of BACTERIOPHAGE MU.
Uterine Inversion definition: A complication of OBSTETRIC LABOR in which the corpus of the UTERUS is forced completely or partially through the UTERINE CERVIX. This can occur during the late stages of labor and is associated with IMMEDIATE POSTPARTUM HEMORRHAGE.
Pericentric Inversion definition: A chromosome inversion involving a segment that includes the centromere.
Paracentric Inversion definition: A chromosome inversion involving a segment that does not include the centromere.
T WAVE INVERSION definition: An electrocardiographic finding of an inversion of the T wave from the expected axis. (NCI)
T Wave Inversion definition: An electrocardiographic finding of an inversion of the T wave from the expected axis.
chromosome 9q duplication/chromosome 9p deletion syndrome definition: Mosaicism for a balanced translocation with partial duplication of the long arm of chromosome 9 and partial deletion of the short arm of chromosome 9 are associated with craniofacial dysmorphism, delayed psychomotor development camptodactyly, brain atrophy, and cardiovascular and intestinal abnormalities.
chromosome X inversion syndrome definition: A structural chromosome aberration, consisting of the inverted reunion of a segment after breakage of a chromosome at two points, resulting in a change in sequence of genes or nucleotides, occurring in association with mild mental retardation, short stature, macro-orchidism, and cleft palate.
Inversion Mutation Abnormality definition: A structural change in genomic DNA where the 5' to 3' order of a nucleotide sequence is completely reversed to the 3' to 5' order relative to its adjacent sequences. This inversion is termed either pericentric, if it includes the centromere of a chromosome, or pancentric, if it excludes the centromere. An inversion mutation abnormality may be heritable or occur somatically.
2-haloacid dehalogenase (configuration-inverting) activity definition: Catalysis of the reactions: (S)-2-haloacid + H2O = (R)-2-hydroxyacid + halide and (R)-2-haloacid + H2O = (S)-2-hydroxyacid + halide. [EC:]
Inversion definition: The act of turning inside out, upside down, or end-for-end.
Sequence Inversion definition: The deletion and reinsertion of a segment of a nucleic acid sequence in the same place, but flipped in an opposite orientation.
Reagents, Molecular Assay, Chromosome Anomaly, Inversion definition: Molecular assay reagents intended for use in identifying stable and irreversible rearrangements in the sequence (i.e., inversion) of one of the normal chromosomes (46 in human beings, including the pair that determines the sex). An inversion is a chromosome rearrangement in which a segment of a chromosome is reversed end to end.
Reagents, Molecular Assay, Chromosome Anomaly, Inversion 16 [inv (16)(p13q22)] definition: Molecular assay reagents intended for use in identifying stable and irreversible rearrangements in the sequence (i.e., inversion) of chromosome 16 [inv(16)(p13q22)]. This inversion is often present in patients with a subgroup of acute myeloid leukemias that have a favorable prognosis. In these cases, the inversion is usually the result of the fusion of the CBF and MYH11 genes.
inversion definition: inversion.
Investition definition: [1] Wirtschaft: Anlage von Kapital in Vermögen, um Gewinn zu erzielen
Inversionswetterlage definition: [1] Meteorologie: Wetterlage in einem Hochdruckgebiet mit weitgehender Windstille, bei der eine Umkehr des vertikalen Temperaturverlaufs erfolgt (die bodennahen Luftschichten sind kälter als die darüber liegenden Luftmassen)
Inversion definition: [1] Umkehr, Umkehrung eine Sache
inversion definition: Changement de l’ordre dans lequel les mots sont ordinairement rangés dans le discours.
inversion definition: Disposition d’un corps qui, au lieu d’avoir sa première subdivision à sa droite, l’a, au contraire, à sa gauche.
inversion definition: Évolution par laquelle les bâtiments qui étaient en tête se trouvent en queue.
inversion definition: Reproduction d’une phrase musicale en prenant les notes dans un ordre renversé ou différent.
inversion definition: Anomalie consistant en ce fait qu’un ou plusieurs organes se trouvent du côté du corps opposé à celui qu’ils occupent normalement.
inversion definition: Attirance sexuelle pour les personnes du même sexe, homosexualité.
pédication definition: Coït anal.
pédication definition: Ce qui caractérise les amours entre mâles.
inversión definition: investissement.
