AbstractThe chromosomes of the Indian muntjac (Muntiacus muntjak, 2n = 6 in females and 2n = 7 in males) are described using the methods of G-, C-, CDAG-, and AgNOR-staining, and in situ localization of 18S, 5.8S, 28S rRNA genes.

Chelidonium majus L. is a medicinal plant well-known as a valuable source of isoquinoline alkaloids, which has a variety of pharmacological properties including anti-viral and anti-bacterial effects. However, considerable intraspecific bio-morphological variability in C. majus complicates raw material identification and verification. For the first ...

AbstractChromosome sets of eight Apodemus peninsulae individuals captured in Gansu Province (Lianhuashan Natural Reserve) were studied for the first time in 2012. Chromosome sets of mice contained from 55 to 62 chromosomes and included 48 A chromosomes and 7–14 additional B chromosomes of different morphologies.

AbstractKaryological and molecular genetic study of the sculpins of the genus Myoxocephalus is conducted. Molecular genetic analysis demonstrates that the genus is heterogeneous in the contemporary composition and is divided into Pacific and Arctic-Atlantic groups. In the Pacific group, a close phylogenetic relationship is found between the species...

The structure of a genome can be described at its simplest by the number of chromosomes and the sex chromosome system it contains. Despite over a century of study, the evolution of genome structure on this scale remains recalcitrant to broad generalizations that can be applied across clades. To address this issue, we have assembled a dataset of 823...

Acute promyelocytic leukemia (APL) with variant RARA translocation, eg, t(11;17), is not sensitive to all-trans retinoic acid and requires distinct chemotherapy. However, there are some leukemic entities that may mimic aspects of the clinical and/or laboratory picture of APL and cause confusion because of karyotype nomenclature. Therefore, recognit...

Cytogenetic data for the genus Cichla Bloch et Schneider, 1801 are still very limited, with only four karyotype descriptions to date. The sum of the available cytogenetic information for Cichla species, points to a maintenance of the diploid number of 48 acrocentric chromosomes, considered a typical ancestral feature in cichlids. In the current stu...

The Amazonian red side-necked turtle Rhynemis rufipes is an endemic Amazonian Chelidae species that occurs in small streams throughout Colombia and Brazil river basins. Little is known about various biological aspects of this species, including its sex determination strategies. Among chelids, the greatest karyotype diversity is found in the Neotrop...

Is there a relationship between karyotype abnormalities in fetuses and children conceived by ICSI and their father's semen parameters? The de novo chromosomal abnormality rate in pre- and postnatal karyotypes of ICSI offspring was higher than in the general population and related to fathers' sperm parameters. Several studies have reported a higher ...

Context Turner syndrome (TS) is a genetic condition that is reported to be associated with a prolonged rate-corrected QT (QTc) interval. Objectives To evaluate the prevalence of QTc prolongation in patients with TS, to compare their QTc intervals with healthy controls, and to investigate whether QTc prolongation is associated with a monosomy 45,X k...
