Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Spontaneous Complete Uterine Rupture in a Nonlaboring, Early Third-trimester Uterus: Missed Diagnosis by Ultrasound

open access: yesAmerican Journal of Perinatology Reports, 2013
Objective Describe potential consequences and remedy for not intermittently auscultating fetal heart tones during travel to the imaging department and misdiagnosing a ruptured uterus on ultrasound as a synechiae.

The Fourier Evaluation of Tracings and Acidosis in Labor: the FETAL Technique [PDF]

open access: yesarXiv, 2019
Adequate fetal and neonatal development depend upon the presence of a normal acid-base environment during pregnancy and the smooth transition from intra-uterine to extra-uterine life. Current methods to assess fetal pH and acid-base status are invasive and carry significant maternal and fetal risks.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

open access: yesAdvanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence

Generation of a TSC2 knockout embryonic stem cell line by CRISPR/Cas9 editing

open access: yesStem Cell Research
Tuberous Sclerosis Complex (TSC) is a severe developmental disorder with various clinical effects, primarily caused by TSC2 gene mutations, often involving loss of function(Henske,et al., 2016).To explore role of TSC2 in human heart development, we ...

Extraction of clinical information from the non-invasive fetal electrocardiogram [PDF]

open access: yesarXiv, 2016
Estimation of the fetal heart rate (FHR) has gained interest in the last century, low heart rate variability has been studied to identify intrauterine growth restricted fetuses (prepartum), and abnormal FHR patterns have been associated with fetal distress during delivery (intrapartum).

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

open access: yesAdvanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Indefinite Fetal Heart Rate Pattern in a Patient with Vasa Previa: A Situation Where Guideline Is Inapplicable.

open access: yesIranian Journal of Public Health, 2014
Most fetal heart rate patterns can be interpreted accurately so that management decisions can be made correctly. How-ever, few fetal heart rate patterns are so ambiguous that the obstetricians cannot interpret them precisely.
