Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

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.

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

Journal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

Cultivar‐Specific Production of Unreduced Pollen in the Ornamental Bigleaf Hydrangea (Hydrangea macrophylla ssp. macrophylla)

Plant Breeding, EarlyView.
ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Induction of triploidy in the zebrafish, Brachydanio rerio (Hamilton)

, 1990
Triploidy was induced in the zebrafish, Brachydanio rerio (Hamilton), by varying all possible combinations of the time after fertilization (AF) (1-3min after insemination), temperature (36-42°C) and shock duration (1-7min).

Prenatal diagnosis of triploidy in second trimester of pregnancy: a series of 4 cases over an eleven-year period / Diagnosticul prenatal al triploidiei în trimestrul al II-lea de sarcină: o serie de patru cazuri depistate în unsprezece ani

Romanian Journal of Laboratory Medicine, 2015
Triploidia este o anomalie cromosomică numerică, caracterizată prin prezenţa a trei seturi haploide de cromosomi. Incidenţa triploidiei este dificil de evaluat, deoarece de obicei produce avort spontan în primul trimestru de sarcină. Incidenţa estimată a

Results from the VANISH study: A prospective multicenter study validating a single‐nucleotide polymorphism‐based noninvasive prenatal test to assess aneuploidy risk in surviving twins of vanishing twin pregnancies

Pregnancy, Volume 2, Issue 6, November 2026.
Abstract Introduction To develop and validate a single‐nucleotide polymorphism (SNP)‐based noninvasive prenatal cell‐free DNA (cfDNA) screening algorithm capable of identifying the cfDNA signal of the living fetus in vanishing twin (VT) pregnancies and assessing that twin's aneuploidy risk. Methods Prospective study enrolling participants ≥18 years old

Incarceration of a gravid uterus with massive placental enlargement and fetal triploidy at 19 weeks of gestation – A case report on the simultaneous presence of two rare conditions

Case Reports in Women's Health, 2023
This article reports a rare case of uterine incarceration in pregnancy concurrent with nonmolar fetal triploidy and massive placental enlargement in a 35-year-old primigravida.

Diploid sperm and the origin of triploidy [PDF]

Human Reproduction, 2002
Trisomy 16, the 45,X monosomy and triploidy are the more frequent chromosome anomalies in spontaneous abortions. Earlier estimations, based on frequencies of diandric triploidy at conception, resulted in a good correlation with the frequencies of diploid sperm in infertile males (up to 1.9%).

One cycle of nelarabine given after induction is well tolerated but does not improve outcome in adults with T‐cell precursor acute lymphoblastic leukemia: Outcome data from the UKALL14 randomized‐controlled trial

HemaSphere, Volume 10, Issue 10, October 2026.
Abstract UKALL14 (NCT01085617) T‐cell arm was a phase 3, randomized‐controlled trial. Adults aged 25–65 years were randomized 1:1 at entry to receive standard of care (SOC) or SOC + nelarabine 1.5 g/m2 (Days 1, 3, and 5) to be administered following second induction. The primary end‐point was event‐free survival (EFS).
