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

open access: yesCiencias 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 ...

Comparative cytogenetics of anembryonic pregnancies and missed abortions in human

open access: yesВавиловский 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)

open access: yesAquaculture, 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,

Unbalanced sex ratio and triploidy in the genus Cyclocephala (Coleoptera: Scarabaeoidea: Dynastidae) in the Lesser Antilles: An example of parthenogenesis on islands?

open access: yesEuropean Journal of Entomology, 2014
Sex ratio and chromosomes studies were performed on six of the seven species of genus Cyclocephala present in the Lesser Antilles. Most sex ratios based on light trapping are skewed, with a frequent, but not exclusive, strong excess of females.

Study Of Triploidy In Humans With A Particular Emphasis On Recurring Triploidy [PDF]

open access: yes, 1995
The purpose of this study was to further the understanding of the causes of triploidy in spontaneous abortions in humans. Triploidy is a chromosomal aberration that can be caused by several erroneous occurrences during gamete formation or fertilization ...

First trimester growth delay: An early marker of triploidy

open access: yes, 2019
Triploidy is one the most common chromosomal abnormality in humans, complicating about 1% of all human pregnancies. Most affected conceptions undergo spontaneous abortion in the first trimester, making the prevalence of second trimester triploidy low ...

Molar and nonmolar triploidy: Recurrence or bad luck

open access: yesClinical Case Reports, 2020
In triploid pregnancies, the parental origin of the extra genome determines the phenotype and placental and fetal outcomes. Molecular genetics and placental pathology enable differentiation of molar vs nonmolar pregnancy to guide future planning.
