An ANA test is considered positive if fluorescence is seen at a titre of 1:40/1:80. Higher titres are more clinically significant as low positives (≤1:160) are found in up to 20% of healthy individuals, especially the elderly. Only around 5% of the healthy population have ANA titres of 1:160 or higher. [8] [53]
Immunofluorescence staining pattern of anti-centromere antibodies on HEp-20-10 cells. Anti-centromere antibodies (ACAs; often styled solid, anticentromere) are autoantibodies specific to centromere and kinetochore function.
3D rendering of centrioles showing the triplets. In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. [1] Centrioles are found in most eukaryotic cells, but are not present in conifers (), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.
An Ohio couple who tortured their five adopted sons in “dungeon”-like conditions and deprived them of food and water, among other abuses, has been sentenced after taking a plea deal.
In Florida State’s December 2023 lawsuit against the ACC, on page 32 of the 38-page complaint, item 151 states: “Florida State be deemed to have issued its formal notice of withdrawal from the ...
Pericentriolar material (PCM, sometimes also called pericent matrix) is a highly structured, [1] dense mass of protein which makes up the part of the animal centrosome that surrounds the two centrioles. The PCM contains proteins responsible for microtubule nucleation and anchoring [2] including γ-tubulin, pericentrin and ninein.

Humans and mice have three centrin genes: Cetn-1, which is typically only expressed in male germ cells, and Cetn-2 and Cetn-3, which are typically only expressed in somatic cells. Centrin-2 is a recombinant GFP-centrin-2 and centriole protein that localizes to centrioles throughout the cell cycle, while centrin-3 seems to stick to the ...
