Transcranial Calcium Macro‐Imaging From the Auditory Cortex of Thy1‐Cre‐Driven GCaMP8 Transgenic Rats

Neuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We generated Thy1‐Cre–driven GCaMP8 transgenic rats by mating Thy1‐Cre rats with knock‐in rats carrying a floxed GCaMP8‐STOP cassette in the β‐actin locus. Robust neuronal GCaMP8 expression enabled transcranial calcium imaging of the auditory cortex, establishing this model as a powerful tool for minimally invasive cortical macro‐imaging and functional

Pitfalls and missing links in current understanding of 4D genomes

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Fetal Growth in Pregnancies Conceived by Single Embryo Transfer: A Prospective Observational Cohort Study During Three Trimesters

Reproductive, Female and Child Health, Volume 5, Issue 2, June 2026.
ABSTRACT Introduction The main aim is to describe fetal growth trajectories in pregnancies conceived by assisted reproductive technology (ART) from gestational week 12 until birth. The secondary aims are to compare ultrasound dating and transfer date estimations of gestational age and to describe birthweight.

Cellular and molecular regulation of mammalian blastocyst hatching

, 2009
In mammals including humans, failure in blastocyst hatching and implantation leads to early embryonic loss and infertility. Prior to implantation, the blastocyst must hatch out of its acellular glycoprotein coat, the zona pellucida (ZP).

Caesarean Scar Ectopic Pregnancy: A Case Study

Sonography, Volume 13, Issue 2, June 2026.
ABSTRACT Caesarean scar ectopic pregnancy (CSEP) occurs when a blastocyst implants into the residual scar from a previous caesarean section delivery, in the anterior lower uterine segment. In this region the endometrium is thin or absent, and may represent a dehiscence of the mucosal margin of the myometrium, with implantation into the myometrium ...
