Compressive-Sensing-based Multidimensional Doppler signal analysis for fetal activity monitoring [PDF]

, 2014
International audienceFetal activity monitoring is an important part of monitoring at-risk pregnancies and labor. Fetal activity parameters (FAP) consist of fetal heart rate (FHR), fetal movements (FM) rate, fetal tone, fetal breathing (FB) and movement.

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

Advanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

The relationship between fetal distress and umbilical venous troponin T during labor [PDF]

Majallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān, 2019
Introduction: For many years, electrocardiogram have been used to diagnose fetal distress around childbirth. If the heart cells are damaged, troponin T is released. Few studies have been performed about the relationship between abnormality of fetal heart
