Endometriosis is a gynecological disease defined as the presence of endometrial tissue outside the uterine cavity, which is caused by various factors. Proteomic analysis of two sets of eutopic endometrial cells collected from the menstrual blood of females with (n=6; n=3) or without (n=6; n=3) endometriosis was performed to identify novel potential biomarkers for endometriosis. The data revealed that samples from endometriosis patients had stem cell characteristics, as they had higher mRNA expression levels of octamer-binding transcription factor 4 (Oct-4), C-X-C chemokine receptor type 4 (CXCR4), SRY-box containing gene 2 (SOX2) and mesenchymal-epithelial transition factor (MET) compared with that of the normal controls. Three proteins, collapsin response mediator protein 2 (CRMP2), ubiquitin carboxyl-terminal hydrolase isozyme L1 (UCH-L1) and myosin regulatory light polypeptide 9 (MYL9), were simultaneously identified from the two sets of samples from females with or without endometriosis by two-dimensional electrophoresis (2-DE). A difference in CRMP2 expression was confirmed with western blotting. Taken together, the results suggest that CRMP2 plays a role in the pathogenesis of endometriosis.
The authors report a case of acute kidney injury (AKI) resulting from menstruation-related disseminated intravascular coagulation (DIC) in an adenomyosis patient. A 40-yr-old woman who had received gonadotropin for ovulation induction therapy presented with anuria and an elevated serum creatinine level. Her medical history showed primary infertility with diffuse adenomyosis. On admission, her pregnancy test was negative and her menstrual cycle had started 1 day previously. Laboratory data were consistent with DIC, and it was believed to be related to myometrial injury resulting from heavy intramyometrial menstrual flow. Gonadotropin is considered to play an important role in the development of fulminant DIC. This rare case suggests that physicians should be aware that gonadotropin may provoke fulminant DIC in women with adenomyosis.
LZD using ICSI pipettes for mechanical AH improves significantly complete hatching, implantation and pregnancy rates in vitrified-thawed blastocyst transfers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
