AutoKary2022: A Large-Scale Densely Annotated Dataset for Chromosome Instance Segmentation [PDF]
arXiv, 2023 Automated chromosome instance segmentation from metaphase cell microscopic images is critical for the diagnosis of chromosomal disorders (i.e., karyotype analysis). However, it is still a challenging task due to lacking of densely annotated datasets and the complicated morphologies of chromosomes, e.g., dense distribution, arbitrary orientations, and ...

Detection of chromosome aberrations in the human interphase nucleus by visualization of specific target DNAs with radioactive and non-radioactive in situ hybridization techniques: diagnosis of trisomy 18 with probe L1.84 [PDF]
, 1986 The localization of chromosome 18 in human interphase nuclei is demonstrated by use of radioactive and nonradioactive in situ hybridization techniques with a DNA clone designated L1.84.

Unified theory of human genome reveals a constrained spatial chromosomal arrangement in interphase nuclei [PDF]
, 2015 We investigate a densely packed, non-random arrangement of forty-six chromosomes (46,XY) in human nuclei. Here, we model systems-level chromosomal crosstalk by unifying intrinsic parameters (chromosomal length and number of genes) across all pairs of chromosomes in the genome to derive an extrinsic parameter called effective gene density.

Circumnutation in the growth of Chara rhizoids
Acta Societatis Botanicorum Poloniae, 2014 The chromosome numbers of 24 species of Achillea L. were determined, among them 4 for the first time (A. chamaemelifolia, A. sulphurea, A. teretifolia, A. vermicularis). A tetraploid form of A. lingulata was found for the first time. The occurrence of di-

Chromosome numbers in. Begonia. 2.
Netherlands Journal of Agricultural Science, 1969 The somatic chromosome numbers are presented of 90 Begonia spp. of African, Asian and American origin, including a few of those previously listed [see H.A., 40: 1600] whose nomenclature or chromosome numbers are reconsidered. Sixteen different numbers were found, ranging between 16 and 76.
