Scanning Electron Microscopy as an Analytical Tool for the Study of Calcified Intrauterine Contraceptive Devices [PDF]

, 1985
Within the endometrial cavity intrauterine contraceptive devices (IUDs) become encrusted with cellular, acellular, and fibrillar substances. Scanning electron microscopy was used to study the crust.

Efficacy and related factors of levonorgestrel‐releasing intrauterine system combined with metformin in fertility‐preserving treatment for atypical endometrial hyperplasia and early endometrial cancer: A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To compare the efficacy of the levonorgestrel‐releasing intrauterine system combined with metformin versus oral progestin combined with metformin in fertility‐preserving treatment for patients with atypical endometrial hyperplasia and early endometrial cancer, and to analyze related factors affecting efficacy.

Membranous dysmenorrhea and decidual casts: A scoping review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Membranous dysmenorrhea, characterized by the expulsion of intact endometrial tissue rather than gradual dissolution during menstruation, occasionally presents as a decidual cast—a complete triangular mold of the uterine cavity. This poorly understood condition is likely underdiagnosed.

Implantable drug delivery system: Frontiers of medicine‐engineering interdisciplinary

Interdisciplinary Medicine, EarlyView.
This review systematically summarizes the driving mechanisms of implantable on‐demand drug delivery systems (IDDS), including endogenous, exogenous, and closed‐loop strategies. It highlights the pivotal roles of flexible electronics and miniaturization in enhancing the tissue conformity and spatial adaptability.

Accessory Cavitated Uterine Malformation (ACUM): A Case Series

Journal of Clinical Ultrasound, EarlyView.
Accessory cavitated uterine malformation (ACUM) can be misdiagnosed as other uterine pathologies, such as mullerian anomalies, adenomyosis or fibroids. Imaging, particularly gynecological ultrasound plays a fundamental role in identifying this condition.

Femoral Skeletal Growth in Early Infancy Assessed by Radiofrequency Echographic Multi‐Spectrometry

Journal of Clinical Ultrasound, EarlyView.
Radiofrequency echographic multi‐spectrometry (REMS) acquisition of raw ultrasound radiofrequency signals from neonatal bone. Signals undergo preprocessing and frequency‐domain analysis to extract spectral features reflecting bone properties. A software‐guided procedure then identifies and selects standardized regions of interest (ROIs).

Fetal Instability and Resuscitative Management During Fetal Intervention: A Retrospective, Descriptive Analysis of 245 Fetal Cardiac and Spina Bifida Procedures

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective The heterogeneity of fetal surgery has led to variability in the nature and frequency of fetal instability. Understanding these differences is critical for optimizing management. Methods We reviewed all fetal atrial septal interventions (FASI) and fetoscopic myelomeningocele (fMMC) repairs with fetal instability performed at our ...

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...
