Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed-wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study. [PDF]

open access: yesActa Obstet Gynecol Scand
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Fetal autonomic responses inferred from heart rate variability during recurrent decelerations without acidosis—An observational study

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Recurrent fetal heart rate (FHR) decelerations without acidosis are frequently observed during labor; however, the underlying autonomic mechanisms remain incompletely understood. This study explored fetal autonomic responses to recurrent decelerations using FHR and FHR variability (FHRV) parameters.

Laparoscopic Resection of Caudate Lobe Liver Tumors in Clinical Practice

open access: yesiNew Medicine, EarlyView.
ABSTRACT The caudate lobe (Couinaud segment I), owing to its deep location in the posterosuperior liver, intimate encirclement by the inferior vena cava (IVC), and close adjacency to the hepatic hilum and major hepatic veins, presents a formidable anatomical challenge for resection.

The Endothelial CXCR Family in Vascular Health and Disease

open access: yesiNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Histological Analysis of Cryopreserved Venous Allografts Used for Liver Transplantation and Hepato‐Biliary‐Pancreatic Surgery

open access: yesJournal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Cryopreserved venous allografts, which we pioneered in 1999 for use in living donor liver transplantation and hepato‐biliary‐pancreatic surgery, are widely used and are believed to preserve vascular architecture with minimal anticoagulation or immunosuppression requirements and patency comparable to autologous grafts.

The Hidden Architecture of Pancreatic Ducts: 3D Anatomical Reconstruction and Its Implication on Pancreatic Resection

open access: yesJournal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background/Purpose Postoperative pancreatic fistula (POPF) is a common complication after pancreatic surgery and its mechanisms remain incompletely understood. While the diameter of the main pancreatic duct is well‐known to be a risk factor of POPF, the impact of branch duct's (BD) anatomy is not known.
