Population structure, fluctuating asymmetry and genetic variability in an endemic and highly isolated Astyanax fish population (Characidae)

Genetics and Molecular Biology, 2004
Morphological and chromosomal markers were used to infer the structure and genetic variability of a population of fish of the genus Astyanax, geographically isolated at sinkhole 2 of Vila Velha State Park, Paraná, Brazil.

Comparative karyotype analysis in diploid and triploid Dolichoplana carvalhoi (Tricladida, Terricola, Rhynchodemidae) from Brazil

Genetics and Molecular Biology, 2007
In this work, we present cytogenetic data for the land planarian Dolichoplana carvalhoi. Two different karyotypes, one diploid (2n = 2x = 14 chromosomes) and one triploid (2n = 3x = 21 chromosomes), corresponding to two morphological body patterns, are ...

The EUROmediCAT Network and Databases: A Resource for Pharmacovigilance in Pregnancy

Pharmacoepidemiology and Drug Safety, Volume 35, Issue 5, May 2026.
ABSTRACT Background The evidence gap relating to the risk of congenital anomalies (CA) associated with first trimester medication exposure in pregnancy is well recognized. Aims We describe the EUROmediCAT network and databases, and the methodological approach to pregnancy pharmacovigilance.

Gene expression response under thermal stress in two Hawaiian corals is dominated by ploidy and genotype

Ecology and Evolution
Transcriptome data are frequently used to investigate coral bleaching; however, the factors controlling gene expression in natural populations of these species are poorly understood.

Society for Maternal‐Fetal Medicine Consult Series #75: Evaluation and management of non‐immune hydrops fetalis

Pregnancy, Volume 2, Issue 2, March 2026.
Abstract Non‐immune hydrops fetalis (NIHF) can result from a multitude of underlying causes, such as fetal genetic diseases, congenital anomalies, infections, fetal arrhythmias, placental tumors, monochorionic twin complications, and other disorders.

The assessment of the effects of genomic heterozygosity and sterility on the performance of triploid brook trout Salvelinus fontinalis

Frontiers in Animal Science
This study analyses diploid and hydrostatic-pressure-induced triploid brook trout (Salvelinus fontinalis) sampled from a fish farm before (360 days post-hatch, d.p.h.) and during the normal time of sexual maturation for pan-sized market fish (555 and 667

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Evidence for viable and stable triploid Trypanosoma congolense parasites

Parasites & Vectors, 2017
Background Recent whole genome sequencing (WGS) analysis identified a viable triploid strain of Trypanosoma congolense. This triploid strain BANANCL2 was a clone of the field isolate BANAN/83/CRTRA/64 that was collected from cattle in Burkina Faso in ...

Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations

BMC Genetics, 2018
Background Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon produced in Norwegian ...
