Rotational Doppler Effect of Vector Beams

Photonics
The optical rotational Doppler effect occurs when vortex beams are scattered by rotating objects and demonstrate the Doppler frequency shifts in scattered beams, which are associated with the optical angular momentum of vortex beams and the relative ...

Post protocol residual thickness as a negative predictor for pharmacological treatment in early pregnancy loss

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To determine the rate of pharmacological treatment failure in early pregnancy loss, assess post‐treatment residua thickness as a predictor of retained products of conception (RPOC), identify a clinically relevant cutoff, and evaluate additional clinical and sonographic predictors. Methods This retrospective cohort study was conducted

A first‐trimester mechanistic framework integrating three Physiopathologic biomarker domains for pre‐eclampsia classification

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To develop and internally validate a mechanistic, three‐domain framework for early classification and prediction of pre‐eclampsia (PE) using first‐trimester angiogenic, uteroplacental, and maternal vascular biomarkers. Methods In a prospective cohort of 1925 singleton pregnancies screened at 11 to 13.6 weeks, placental growth factor (

Second‐trimester multimetabolite panel for early preeclampsia rule‐out

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...
