Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding

open access: yesAdvanced Materials, EarlyView.
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

The paradox of pregnancy : an update on the immunology of early pregnancy [PDF]

open access: yes, 2008
Pregnancy is an altered physiological state where an organism essentially foreign to the individual carrying it, grows, develops and at an appropriate time probably initiates a series of signals which lead to its safe expulsion from the woman's body. The

FOXO1 regulates uterine epithelial integrity and progesterone receptor expression critical for embryo implantation

open access: yesPLoS Genetics, 2018
Successful embryo implantation requires a receptive endometrium. Poor uterine receptivity can account for implantation failure in women who experience recurrent pregnancy loss or multiple rounds of unsuccessful in vitro fertilization cycles.

Vaginal and endometrial microbiome dysbiosis associated with adverse embryo transfer outcomes

open access: yesReproductive Biology and Endocrinology
Background Assisted reproductive technology (ART) is the most effective method to treat infertility and the pathogenesis of implantation failure after in vitro fertilization-embryo transfer (IVF-ET) is a challenging filed in infertility.

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]

open access: yes, 2014
Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

New insights into progesterone receptor signaling in the endometrium required for embryo implantation.

open access: yesJournal of Molecular Endocrinology, 2019
Progesterone's ability to maintain pregnancy in eutherian mammals highlighted this steroid as the "hormone of pregnancy". It was the unique "pro-gestational" bioactivity of progesterone that enabled eventual purification of this ovarian steroid to ...

Human Chorionic Gonadotropin-Mediated Immune Responses That Facilitate Embryo Implantation and Placentation

open access: yesFrontiers in Immunology, 2019
Human chorionic gonadotropin (hCG) serves as one of the first signals provided by the embryo to the mother. Exactly at the time when the first step of the implantation process is initiated and the blastocyst adheres to the maternal endometrium, the ...
