Upside-Down and Inside-Out Signs in Uterine Inversion.

Journal of clinical medicine research

Kawano H, Hasegawa J, Nakamura M, Maruyama D, Arakaki T, Ono A, Miyake Y, Sekizawa A.
PMID: 27298665
J Clin Med Res. 2016 Jul;8(7):548-9. doi: 10.14740/jocmr2538w. Epub 2016 May 29.

Uterine inversion is a rare condition that is accompanied by massive hemorrhaging and shock, resulting in a maternal emergency. The diagnosis of uterine inversion is often difficult due to massive postpartum hemorrhaging. Ultrasonography is useful for the diagnosis in...

A hybrid material consisting of CaTaO2N (a perovskite oxynitride semiconductor having a band gap of 2.5 eV) and a binuclear Ru(II) complex photocatalytically produced HCOOH via CO2 reduction with high selectivity (>99%) under visible light (λ>400 nm). Results of...

Ultrafast Relaxation Dynamics in trans-1,3-Butadiene Studied by Time-Resolved Photoelectron Spectroscopy with High Harmonic Pulses.

The journal of physical chemistry letters

Makida A, Igarashi H, Fujiwara T, Sekikawa T, Harabuchi Y, Taketsugu T.
PMID: 26270380
J Phys Chem Lett. 2014 May 15;5(10):1760-5. doi: 10.1021/jz5003567. Epub 2014 May 07.

In trans-1,3-butadiene, the ultrafast relaxation from the doubly excited state 2(1)Ag and the corresponding recovery of the ground state 1(1)Ag were observed simultaneously for the first time by time-resolved photoelectron spectroscopy (TRPES) using 29.5 eV high harmonic pulses. The...

Perinatal Management for a Pregnant Woman with an MYH9 Disorder.

Case reports in obstetrics and gynecology

Yamashita Y, Matsuura R, Kunishima S, Oikawa Y, Ariizumi H, Hamada S, Shirato N, Matsuoka R, Ogawa K, Sekizawa A.

Case Rep Obstet Gynecol. 2016;2016:6730174. doi: 10.1155/2016/6730174. Epub 2016 Jun 29.

We diagnosed a primipara woman with an MYH9 disorder during her pregnancy. A peripheral blood smear with an immunofluorescence analysis is the established method of diagnosing MYH9 disorders. We provided genetic counseling, as required, which included apprising the woman...

Visible-light-driven CO2 reduction with carbon nitride: enhancing the activity of ruthenium catalysts.

Angewandte Chemie (International ed. in English)
