Comparison of Pregnancy Rate and Effective Factors following Fresh and Frozen Embryo Transfer in Women undergoing Assisted Reproductive Techniques (ART) [PDF]
Majallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān, 2017 Introduction: Embryo cryopreservation is potentially the best method to increase pregnancy rate for the women at risk of OHSS (Ovarian Hyper stimulation Syndrome) and the women at risk of losing ovarian function.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

International Journal of Reproductive BioMedicine, 2022 Background: Embryo quality may affect birth weight among neonates born through assisted reproductive technology. There are very limited studies assessing the adverse effect of transferring a poor-quality embryo with a good-quality one on neonatal ...
