Deep learning auto‐contouring of target and organs‐at‐risk on post‐catheter implant CT images for prostate HDR brachytherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Accurate delineation of the prostate and surrounding organs‐at‐risk (OARs) is essential for HDR prostate brachytherapy. Manual contouring on post‐catheter CT images is time‐consuming and prone to variability due to artifacts and anatomical deformation from the implanted brachytherapy catheters.

Placental Site Trophoblastic Tumor Acquires Immune Functions by Incorporating Host Maternal Genes

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
PSTT cells, through cell fusion with B cells, incorporate abundant non‐inherited maternal genes that are detectable by DNIMA. These hybrid cells acquire immunotherapy‐resistant genetic changes and increase the expression of B cell‐derived immune‐related molecules such as Ig, HLA, LILRB, SIGLEC10, and so on, creating an immunotolerant environment around

Implantation‐On‐Chip: An AI‐Based Platform for Monitoring the Embryo Trophoblast–Endometrial Stroma Cross Talk With Xenobiotics Interference

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 9, September 2026.
We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...

Delayed Diagnosis of Tuberous Sclerosis Complex Presenting as Abnormal Uterine Bleeding: A Case Report and Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Tuberous sclerosis complex (TSC) is a rare multisystem genetic disorder characterized by the development of hamartomatous lesions in multiple organs. Although neurologic and dermatologic manifestations commonly lead to diagnosis during childhood, some patients remain undiagnosed until adulthood because of atypical presentations.

Squamous Cell Carcinoma Arising in a Mature Cystic Teratoma of the Ovary Presenting With a Ruptured Sister Mary Joseph Nodule: A Rare Case Report From Northern Tanzania

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Squamous cell carcinoma arising from malignant transformation of a mature cystic teratoma is an exceptionally rare ovarian malignancy, and metastatic umbilical involvement is particularly uncommon. Diagnosis and treatment planning are challenging due to overlapping presentation with epithelial ovarian cancer, particularly in settings with ...
