Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

open access: yesAdvanced Science, Volume 13, Issue 39, 13 July 2026.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

Facilitating Genetic Testing for Perinatal Demise: Development of a Multidisciplinary Workflow

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1273-1285, June 2026.
ABSTRACT Genetic contributors to perinatal demise are common but frequently undiagnosed due to clinical and logistical barriers. We aimed to improve access to genetic for intrauterine fetal demise (IUFD), stillbirth, and early neonatal death by developing a multidisciplinary workflow.

Second-Trimester Diagnosis of Triploidy: A Series of Four Cases

open access: yesAmerican Journal of Perinatology Reports, 2013
Triploidy occurs in 2 to 3% of conceptuses and accounts for approximately 20% of chromosomally abnormal first-trimester miscarriages. As such, triploidy is estimated to occur in 1 of 3,500 pregnancies at 12 weeks', 1 in 30,000 at 16 weeks', and 1 in 250 ...

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.
