The Influence of a Crosshair Visual Aid on Observer Detection of Simulated Fetal Heart Rate Signals

American Journal of Perinatology Reports, 2016
Objective To determine whether a visual aid overlaid on fetal heart rate (FHR) tracings increases detection of critical signals relative to images with no visual aid.

Fetal respiratory movements improve reliability of heart rate variability and suggest a coupling between fetal respiratory arrhythmia and vagal activity

Physiological Reports, 2022
Fetal heart rate variability (FHRV) reflects autonomic cardiac regulation. The autonomic nervous system constantly adjusts the heart rate to maintain homeostasis.

Novel Biologically Active Glass Fiber Functionalized Using Magnesium Phosphate Cement Promotes Bone and Vascular Regeneration

Advanced Biology, EarlyView.
In this study, a new type of bioactive glass fiber ‐based composite magnesium phosphate bone cement is prepared and verified that its mechanical strength and biological properties. In addition, the cement may have played a biologically active role in the Notch and HIF signaling pathways.

Multi-scale sample entropy and recurrence plots distinguish healthy from suffering foetus [PDF]

, 2012
International audienceCurrently, the assessment of the state of fetal well-being using ultrasound is a challenge in the obstetrical world. To assess the fetal well-being, parameters are derived from the fetal heart rate and fetal movements.

Extracting fetal heart beats from maternal abdominal recordings: Selection of the optimal principal components [PDF]

, 2014
This study presents a systematic comparison of different approaches to the automated selection of the principal components (PC) which optimise the detection of maternal and fetal heart beats from non-invasive maternal abdominal recordings.

Current methods of non-invasive fetal heart rate surveillance

Clinical and Experimental Obstetrics & Gynecology, 2020
Introduction: As accurate fetal evaluation during labor is essential, there is a continuous need for better noninvasive ways of monitoring. Electronic fetal monitoring (EFM) is an essential tool towards effective fetal assessment during labor, with the ...

Fetal heart rate throughout pregnancy [PDF]

American Journal of Obstetrics and Gynecology, 1972
Abstract Serial fetal heart rate (FHR) determinations were made from early pregnancy to term in 24 healthy fetuses by means of an ultrasonic device. A decreasing FHR pattern was noticed from the eleventh through the thirtieth weeks, after which the values remained more stable (about 140 beats per minute) until term.

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Fetal Heart Rate Variability Is Affected by Fetal Movements: A Systematic Review

Frontiers in Physiology, 2020
Introduction: Fetal heart rate variability (FHRV) evaluates the fetal neurological state, which is poorly assessed by conventional prenatal surveillance including cardiotocography (CTG).

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

Advanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...
