Adversarial Multiscale Feature Learning for Overlapping Chromosome Segmentation [PDF]
arXiv, 2020 Chromosome karyotype analysis is of great clinical importance in the diagnosis and treatment of diseases, especially for genetic diseases. Since manual analysis is highly time and effort consuming, computer-assisted automatic chromosome karyotype analysis based on images is routinely used to improve the efficiency and accuracy of the analysis.

ChrSNet: Chromosome Straightening using Self-attention Guided Networks [PDF]
arXiv, 2022 Karyotyping is an important procedure to assess the possible existence of chromosomal abnormalities. However, because of the non-rigid nature, chromosomes are usually heavily curved in microscopic images and such deformed shapes hinder the chromosome analysis for cytogeneticists.

Acute Myeloid Leukemia: 2025 Update on Diagnosis, Risk‐Stratification, and Management
American Journal of Hematology, EarlyView.ABSTRACT Disease Overview Acute myeloid leukemia (AML) is a bone marrow stem cell cancer that is often fatal despite available treatments. Diagnosis, risk assessment, monitoring, and therapeutic management of AML have changed dramatically in the last decade due to increased pathophysiologic understanding, improved assessment technology, and the ...

Phylogenetic inferences of Atelinae (Platyrrhini) based on multi-directional chromosome painting in Brachyteles arachnoides, Ateles paniscus paniscus and Ateles b. marginatus [PDF]
, 2005 We performed multi-directional chromosome painting in a comparative cytogenetic study of the three Atelinae species Brachyteles arachnoides, Ateles paniscus paniscus and Ateles belzebuth marginatus, in order to reconstruct phylogenetic relationships ...

The Karyotype Ontology: a computational representation for human cytogenetic patterns [PDF]
arXiv, 2013 The karyotype ontology describes the human chromosome complement as determined cytogenetically, and is designed as an initial step toward the goal of replacing the current system which is based on semantically meaningful strings. This ontology uses a novel, semi-programmatic methodology based around the tawny library to construct many classes rapidly ...

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 ...

TP53‐Mutated Myeloid Neoplasms: 2024 Update on Diagnosis, Risk‐Stratification, and Management
American Journal of Hematology, EarlyView.ABSTRACT Alterations in the tumor suppressor gene TP53 are common in human cancers and are associated with an aggressive nature. Approximately 8%–12% of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) harbor TP53 mutations (TP53mut) and present immense challenges due to inherent chemoresistance and poor outcomes.
