Combined fresh and frozen embryo transfer resulting in a twin delivery [PDF]

Human Reproduction, 1998
We report the delivery of non-identical twins resulting from the combined transfer of one fresh and one frozen embryo to a 31 year old patient. To our knowledge, this is the first reported case where both a fresh and a frozen embryo implanted in the same cycle led to non-identical twins.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Live birth after fresh versus frozen single blastocyst transfer (Frefro-blastocyst): study protocol for a randomized controlled trial

Trials, 2017
Background Multiple pregnancies are one of the major safety concerns of in vitro fertilization (IVF) due to the increased risk of maternal and neonatal complications.

Top‐quality embryo transfer is associated with lower odds of ectopic pregnancy

Acta Obstetricia et Gynecologica Scandinavica, 2022
Introduction The incidence of ectopic pregnancy is up to four times higher after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) than in spontaneous pregnancies, and the risk of ectopic pregnancy is increased by tubal factor ...

Children conceived by in vitro fertilisation after fresh embryo transfer [PDF]

Archives of Disease in Childhood - Fetal and Neonatal Edition, 1997
AIMS To compare the outcome in in vitro fertilisation (IVF) children (after fresh embryo transfer) from multiple and singleton births with one another, and with normally conceived control children. METHODS A cohort of 278 children (150 singletons ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Freeze-all policy for in vitro fertilization in women with normal response to ovarian stimulation

Einstein (São Paulo), 2021
Objective To answer the question if the freeze-all strategy and subsequent frozen embryo transfer is preferable to fresh embryo transfer for patients with normal response to ovarian stimulation (4 to 15 oocytes recovered) during in vitro fertilization ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Oocyte maturation triggers in high-responders: a report on 1,217 consecutive cycles

Reproduction and Fertility
Using a large patient series, we aimed to evaluate, in a high-responder population, the effect of triggering oocyte maturation with human choriogonadotropin (hCG) or with a gonadotropin-releasing hormone agonist (GnRHa).

Fertility and pregnancy outcomes following fresh versus frozen-thawed embryo transfer in assisted reproductive technology [PDF]

, 2019
Background and aims: Assisted reproductive technology has provided great hope for millions of infertile couples. In recent years, frozen-thawed embryo transfer has no longer been merely an add-on to the conventional fresh embryo transfer.
