Unrecognized maternal heart rate artefact in cases of perinatal mortality reported to the United States Food and Drug Administration from 2009 to 2019: a critical patient safety issue

open access: yesBMC Pregnancy and Childbirth, 2019
Background Maternal heart rate artefact is a signal processing error whereby the fetal heart rate is masked by the maternal pulse, potentially leading to danger by failure to recognize an abnormal fetal heart rate or a pre-existing fetal death.

Programmable Functional Silicification of DNA Origami Nanostructures

open access: yesAdvanced Materials, EarlyView.
This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Comparing accuracy of obstetric sonography and fetal echocardiography during paediatric cardiology consultation in prenatal diagnosis of congenital heart disease [PDF]

open access: yes, 2015
OBJECTIVE: Compare the diagnostic accuracy of fetal echocardiogram performed by obstetrician alone and that performed jointly by obstetrician and paediatric cardiologist for congenital heart disease. METHOD: All cases of suspected fetal congenital heart

Evaluation of fetal cardiac morphology and function in hypertensive disorders of pregnancy using Fetal HQ technology combined with uterine artery ultrasound parameters

open access: yesFrontiers in Cardiovascular Medicine
ObjectiveHypertensive disorders of pregnancy (HDP) significantly affect both maternal and fetal health, with uterine artery hemodynamic parameters playing a critical role in assessing fetal well-being, though they do not provide early insights into fetal

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

open access: yesAdvanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

S‐Nitrosothiols as Thiol‐Protecting Groups for Controlled Thiol‐Maleimide Crosslinking of Homogeneous Soft Hydrogels

open access: yesAdvanced Materials, EarlyView.
Rapid thiol‐maleimide addition frequently outpaces mixing, resulting in heterogeneous hydrogels. S‐nitrosothiols act as thiol‐protecting groups, allowing uniform mixing with maleimide‐functionalized polymers before gelation. Sodium thiosulfate or sodium ascorbate then regenerates thiols on demand, triggering controlled thiol‐maleimide crosslinking ...

Esterified Cholesterol Conjugates Enable LNP‐Mediated mRNA Delivery to the Blood–Brain Barrier Following Intravenous Administration

open access: yesAdvanced Materials, EarlyView.
A cholesterol‐conjugated lipid library enabled the identification of a ligand‐free LNP platform for efficient mRNA delivery to brain endothelial cells via systemic administration. This platform achieves selective BBB targeting without disrupting barrier integrity, and enables modulation of neuroinflammation and vascular function without requiring trans‐

A principal components approach to parent-to-newborn body composition associations in South India [PDF]

open access: yes, 2009
Background: size at birth is influenced by environmental factors, like maternal nutrition and parity, and by genes. Birth weight is a composite measure, encompassing bone, fat and lean mass. These may have different determinants. The main purpose of this
