Tenuazonic acid from Stemphylium loti inhibits the plant plasma membrane H⁺‐ATPase by a mechanism involving the C‐terminal regulatory domain

Peter K. Bjørk, Silas A. Rasmussen, Sisse K. Gjetting, Nanna W. Havshøi, more

Pathogenic fungi often target the plant plasma membrane (PM) H⁺‐ATPase during infection. To identify pathogenic compounds targeting plant H⁺‐ATPases, we screened extracts from 10 Stemphylium species for their effect on H⁺‐ATPase activity. We identified Stemphylium loti extracts as potential H⁺‐ATPase inhibitors, and through chemical separation and analysis, tenuazonic acid (TeA) as a potent H⁺...

Single umbilical artery and risk of congenital malformation: population‐based study in Norway

C. Ebbing, J. Kessler, D. Moster, S. Rasmussen

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 510 - 515

Objectives Single umbilical artery (SUA) is associated with congenital malformations in most organ systems, but reported findings have not been consistent. While it has been suggested that genetic and persisting environmental factors influence the development of SUA, it is not known whether there is an increased risk of recurrence in a subsequent pregnancy of the same woman. The aims of this study...

Multicenter randomized trial exploring effects of simulation‐based ultrasound training on obstetricians' diagnostic accuracy: value for experienced operators

L. A. Andreasen, A. Tabor, L. N. Nørgaard, C. Ringsted, more

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 523 - 529

Objective To explore the effects of simulation‐based ultrasound training on the accuracy of fetal weight estimation in the third trimester among obstetricians with different levels of clinical experience. Methods This was a multicenter, randomized pre–post‐test practical trial conducted between March 2016 and January 2018. Obstetricians with different levels of clinical experience were randomized...

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 441 - 449

Objective To report the perinatal outcome of singleton pregnancies complicated by placental chorioangioma diagnosed on prenatal ultrasound. Methods MEDLINE, EMBASE, CINAHL and ClinicalTrials.gov databases were searched for studies reporting the outcome of pregnancies complicated by placental chorioangioma. Inclusion criteria were singleton pregnancy diagnosed with placental chorioangioma on prenatal...

Diagnosis of fetal defects in twin pregnancies at routine 11–13‐week ultrasound examination

A. Syngelaki, B. Cimpoca, E. Litwinska, R. Akolekar, more

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 474 - 481

Objectives To examine the performance of the routine 11–13‐week scan in detecting fetal defects in twin pregnancies and to examine if, in pregnancies with a fetal defect, compared to those with normal fetuses, there is increased incidence of nuchal translucency thickness (NT) ≥ 95^th and ≥ 99^th percentiles or intertwin discordance in crown–rump length (CRL) ≥ 10% and ≥ 15%. Methods This was a retrospective...

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 546 - 551

Objective To assess the long‐term outcome of postmenopausal women diagnosed with non‐atypical endometrial hyperplasia (NEH). Methods This was a retrospective study of women aged 55 or older who underwent endometrial sampling in our academic medical center between 1997 and 2008. Women who had a current or recent (< 2 years) histological diagnosis of NEH were included in the study group and were...

Value of first‐trimester ultrasound in prediction of third‐trimester sonographic stage of placenta accreta spectrum disorder and surgical outcome

G. Calí, I. E. Timor‐Tritsch, F. Forlani, J. Palacios‐Jaraquemada, more

Ultrasound in Obstetrics & Gynecology > 55 > 4 > 450 - 459

Objectives To explore whether early first‐trimester ultrasound can predict the third‐trimester sonographic stage of placenta accreta spectrum (PAS) disorder and to elucidate whether combining first‐trimester ultrasound findings with the sonographic stage of PAS disorder can stratify the risk of adverse surgical outcome in women at risk for PAS disorder. Methods This was a retrospective analysis...
