Impact of preimplantation genetic testing on the incidence of monochorionic diamniotic pregnancies in single blastocyst frozen-thawed embryo transfers: a retrospective cohort study spanning 10 years

BMC Pregnancy and Childbirth
Objective This study aimed to explore the associations between assisted reproductive technology (ART) modality and chorionicity in monozygotic twinning pregnancies following single blastocyst frozen-thawed embryo transfer.

Preliminary Analysis of CpG, CHG and CHH Methylation in the Mitochondrial Control Region of Dogs With Malignant Mammary Gland Tumours

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT Canine mammary tumours (CMTs) are one of the most frequently observed malignancies in female dogs. Many studies have investigated epigenetic changes in CMT at the nuclear level, yet the role of mtDNA methylation, particularly in the D‐loop region, remains largely unexplored.

Comprehensive Evaluation of Language, Speech, and Communication Skills in 24‐ to 36‐Month‐Old Twins and Singletons: Developmental Differences and Associated Factors

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Objective Early language development forms the foundation for cognitive, social, and academic skills. This study aimed to compare the language, speech, and communication skills of twins and singleton children aged 24–36 months and to explore associations with sociodemographic, biological, and environmental factors in the Turkish population ...

Managing TRAP Sequence Conservatively: A Case Report of Full‐Term Pregnancy With Favorable Outcome

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Acardiac twinning, also known as Twin reversed arterial perfusion (TRAP) sequence, is a rare anomaly seen exclusively in monochorionic twin pregnancies. It occurs due to abnormal placental vascular anastomoses, allowing retrograde perfusion from healthy “pump” twin to severely malformed twin lacking a functional heart.

Examining the Utility of the Mammalian Methylation Array for Pan-Mammalian Analysis of Monozygotic Twinning

Epigenomes
Background/Objectives: Human identical twins are born at a rate of 3–4 per 1000 live births. Many other mammals also occasionally produce monozygotic twins, referred to as sporadic polyembryony. The underlying mechanisms are unknown.

Machine Learning on Magnetoencephalography Data Yields Generalizable Low‐Dimensional Neural Fingerprints That Distinguish Individuals Across Task Conditions

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
Bayesian Reduced Rank Regression model was utilized to extract individual features from various metrics derived from resting and task magnetoencephalography recordings. The model remained generalizable at typical neuroimaging sample sizes (20–44).

A Multidimensional Data Set for Obsessive‐Compulsive Disorder to Strengthen Research and Care: A Cross‐Sectional Delphi Study

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Obsessive‐compulsive disorder (OCD) is a complex psychiatric condition marked by persistent obsessions and compulsions, leading to significant disability and reduced quality of life. Despite effective treatments, delays in diagnosis and fragmented data collection hinder optimal care. Current assessment tools focus primarily

A synchronized unique presentation of inguinal hernia in infantile twins

Egyptian Pediatric Association Gazette
Background Female structures such as the ovaries, fallopian tubes, ligaments, and uterus are rarely encountered inside a hernial sac. The prevalence of groin hernias containing parts of female genitalia remains unknown. Occurrence in monozygotic twins is

The Divergent Effects of Nicotinamide Riboside and High‐Intensity Exercise Training on Skeletal Muscle Epigenetic Aging

Aging Cell, Volume 25, Issue 8, August 2026.
This study investigated the effects of nicotinamide riboside supplementation and high‐intensity interval training on skeletal muscle epigenetic aging. Our findings reveal that both interventions may modify epigenetic aging, with the muscle‐specific MEAT and DunedinPACE clocks showing the most responsiveness and links to mitochondrial abundance ...

Can We Improve the Prediction of Early Onset Mania and Hypomania in the Community?

Bipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Background There is broad agreement that the onset of bipolar disorders (BD) can be predicted by using combined estimates of familial, genetic and clinical risk. However, there is a lack of consensus about the operationalisation of different risk attributes (e.g., symptoms vs.
