Origin and development of uniparental and polyploid blastomeres

iScience
Summary: Whole-genome (WG) abnormalities, such as uniparental diploidy and triploidy, cause fetal death. Occasionally, they coexist with biparental diploid cells in live births. Understanding the origin and early development of WG abnormal blastomeres is

Negative selection pressure against premature protein truncation is reduced by alternative splicing and diploidy [PDF]

, 2004
The importance of alternative splicing in many genomes has raised interesting questions about its role in evolution. We analyzed 13 384 full-length transcript isoforms from human and 2227 isoforms from mouse to identify sequences containing premature ...

Cell division in early logarithmic cultures.

, 2016
Comparison of diploidy percentage with haemocytometer counts of gametogenesis ploidy time course. The largest increase in the cell population occurs prior to the peak in diploid cells, slowing as cell division ceases.

Somatic chromosomal changes of rat liver cells during in vitro cultivation [PDF]

, 1971
In order to examine how long diploid cells can be maintained in vitro cultivation without any chromosomal aberrations and to evaluate the mechanism of chromosomal heteroploid transformation, changes of chromosomes were studied in the course of serial in ...

Hybrid incompatibilities are affected by dominance and dosage in the haplodiploid wasp Nasonia

Frontiers in Genetics, 2015
Study of genome incompatibilities in species hybrids is important for understanding the genetic basis of reproductive isolation and speciation. According to Haldane’s rulehybridization affects the heterogametic sex more than the homogametic sex.

Triploidy induction in Heterobranchus longifilis (Family: Clariidae) by cold shock [PDF]

, 1999
Triploid was induced in African Catfish (Heterobranchus longifilis) by cold shocking activated eggs at 5 degree C for forty minutes starting 3-4 minutes after fertilization.

Macrocephaly in Bull Spermatozoa Is Associated with Nuclear Vacuoles, Diploidy and Alteration of Chromatin Condensation

, 2009
Spermatozoa from 2 dairy AI (artificial insemination) bulls (A and B), identified by their abnormal spermiogram with cells depicting frequent macrocephaly, double tails and nuclear vacuoles, were case-investigated and compared to normal spermatozoa from ...

A Case with Neurofibromatosis and Chronic Myeloid Leukemia in Blastic Crisis Treated with Imatinib

Middle East Journal of Cancer, 2014
A 61-year-old female presented with complaints of fever, general weakness and hepatosplenomegaly. She had a history of nonfamilial peripheral neurofibromatosis diagnosed as von Recklinghausen's disease since 30 years previous. Physical examination was
