Effectiveness of high‐dose transvaginal progesterone supplementation for women who are undergoing a frozen‐thawed embryo transfer

Reproductive Medicine and Biology, 2018
Purpose To evaluate the effectiveness of high‐dose progesterone supplementation for women who are undergoing a frozen‐thawed embryo transfer (FET). Methods Among the 2010 FET cycles that were included in the present study, 1188 were 1200 mg/d of vaginal ...

Very Early Administration of Progesterone for Acute Traumatic Brain Injury

New England Journal of Medicine, 2014
BACKGROUND Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Progesterone has been shown to improve neurologic outcome in multiple experimental models and two early-phase trials involving patients with TBI.

Interdigitale Aptamer‐Sensoren mit komplementären Messkanälen zur schnellen Detektion kleiner Moleküle in Biofluiden

Angewandte Chemie, EarlyView.
Ein elektrochemischer Aptamer‐Sensorchip nutzt Interdigitalelektroden mit selektiver Monoschicht‐Funktionalisierung, um Dopamin und Cortisol mittels robuster komplementärer „Signal‐Off/On“‐Antworten zu detektieren. Diese Dual‐Channel‐Signalumwandlung ermöglicht eine schnelle Detektion innerhalb von 5–30 min bei geringen Probenvolumina in künstlicher ...

Impact of serum progesterone levels and rescue progesterone supplemental luteal support on pregnancy outcomes in frozen embryo transfer: a controlled trial

BMC Pregnancy and Childbirth
Background The role of serum progesterone levels and the benefit of rescue luteal support in frozen embryo transfer (FET) cycles remain debated. While low serum progesterone has been linked to poorer outcomes, evidence on whether supplementation improves

Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

Angewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

Serum progesterone distribution in normal pregnancies compared to pregnancies complicated by threatened miscarriage from 5 to 13 weeks gestation: a prospective cohort study

BMC Pregnancy and Childbirth, 2018
Background Progesterone is a critical hormone in early pregnancy. A low level of serum progesterone is associated with threatened miscarriage. We aim to establish the distribution of maternal serum progesterone in normal pregnancies compared to ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Divergent behavior of cyclin E and its low molecular weight isoforms to progesterone-induced growth inhibition in MCF-7 cells

Advanced Biomedical Research, 2015
Background: Progesterone is a steroid hormone that modulates proliferation and differentiation in a cell phase and tissue-specific manner. Its function in breast cancer cells is of great significance since it can predict susceptibility of tumor cells to ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...
