Usefulness of combined NGS and QF‐PCR analysis for product of conception karyotyping

Reproductive Medicine and Biology, 2022
Purpose Since chromosomal abnormalities can be detected in more than half of miscarriages, cytogenetic testing of the product of conception (POC) can provide important information when preparing for a subsequent pregnancy. Conventional karyotyping is the

Effects of cold-shock triploidy induction treatment on cell cleavage, hatching rate, and survival of triploid larvae of spotted sand bass (Paralabrax maculatofasciatus)

Ciencias Marinas, 2016
Three experiments assessed the effects of cold-shock induced triploidy on (1) the incidence of abnormal cell cleavage during embryogenesis, (2) hatching success and the proportion of live yolk-sac larvae in normally cleaved versus abnormally cleaved ...

Interacting Effects of Cell Size and Temperature on Gene Expression, Growth, Development and Swimming Performance in Larval Zebrafish

Frontiers in Physiology, 2021
Cell size may be important in understanding the thermal biology of ectotherms, as the regulation and consequences of cell size appear to be temperature dependent.

Comparative cytogenetics of anembryonic pregnancies and missed abortions in human

Вавиловский журнал генетики и селекции, 2023
Miscarriage is an important problem in human reproduction, affecting 10–15 % of clinically recognized pregnancies. The cases of embryonic death can be divided into missed abortion (MA), for which the ultrasound sign of the embryo death is the absence of ...

Growth and survival of diploid and triploid bata, Labeo bata (Hamilton, 1822)

Aquaculture, Fish and Fisheries, 2021
Bata (Labeo bata), an indigenous, freshwater minor carp, is a great delicacy in Bangladesh. In its natural fishery, bata contributes significantly to the health and nutritional security of a large section of the fisher communities in Bangladesh. However,

Diploid Gynogenesis Induced by Heat Shock after Activation with UV-Irradiated Sperm in Rainbow Trout (Oncorhynchus Mykiss)

Scientific Papers Animal Science and Biotechnologies, 2023
Gynogenesis is a technique used to generate diploid individuals with genetic material exclusively of maternal origin. In this study we test the hypothesis that heat shock treatment of rainbow trout eggs, activated with UV irradiated sperms, leads to the ...

Cytotaxonomy, heterochromatic polymorphism and natural triploidy of a species of Astyanax (Pisces, Characidae) endemic to the Iguaçu river basin

Brazilian Archives of Biology and Technology, 2007
Cytogenetic analysis with Astyanax sp. D revealed a karyotype of 2n=50 with 2M+26SM+6ST+16A, besides a triploid specimen showing 2n=75 chromosomes (3M+39SM+9ST+24A). C-banding strongly stained the terminal regions of several SM-ST-A chromossomes.

Identification of major congenital malformations based on healthcare databases in France: A proof‐of‐concept study using the epi‐meres nationwide mother–child register

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Clinical Utility of Nuchal Translucency Measurement in First‐Trimester Ultrasound Screening in a Setting With First‐Tier NIPT for Aneuploidy Screening

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To investigate the additional clinical value of nuchal translucency (NT) measurement at the first‐trimester anomaly scan (FTAS) in a setting with first‐tier non‐invasive prenatal testing (NIPT). Method This nationwide prospective cohort study, part of the IMITAS study on FTAS implementation, included all pregnancies with increased NT

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.
