Passive fetal heart rate monitoring apparatus and method with enhanced fetal heart beat discrimination [PDF]

open access: yes, 1996
An apparatus for acquiring signals emitted by a fetus, identifying fetal heart beats and determining a fetal heart rate. Multiple sensor signals are outputted by a passive fetal heart rate monitoring sensor.

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

open access: yesAdvanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Heart disease in infants of diabetic mothers [PDF]

open access: yes, 2000
Congenital anomalies occur more commonly in infants born to diabetic mothers, and cardiac defects predominate. Although respiratory problems are also frequently found in those infants, they need to be differentiated from cardiovascular problems that ...

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

open access: yesAdvanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Fetal growth, early life circumstances, and risk of suicide in late adulthood.

open access: yes, 2011
Recent studies in Sweden and Scotland have found early life conditions to be associated with increased risk of attempted and completed suicide in adolescence and young adulthood. It is not known, however, whether early life conditions affect suicide risk

Identification of heart rate-associated loci and their effects on cardiac conduction and rhythm disorders [PDF]

open access: yes, 2011
Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we identified 14 new loci associated with heart rate and ...

Tumor‐Targeted Hyaluronic Acid/Tannic Acid‐Engineered Oxygen Nanogenerators With IR780 Payloads Enable Dual‐Mode Glutathione Depletion and Effective Singlet Oxygen Generation for Melanoma Treatment

open access: yesAdvanced Healthcare Materials, EarlyView.
A hyaluronic acid/tannic acid‐engineered Prussian blue oxygen nanogenerator loaded with IR780 is developed to enhance melanoma phototherapy. By integrating tumor targeting, oxygen self‐supply, and dual‐mode glutathione depletion, the nanoplatform effectively overcomes hypoxia and antioxidant defenses, potentiating synergistic photothermal/photodynamic ...

Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

open access: yesAdvanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,

Fetal bradycardia associated with left ventricle noncompaction diagnosed as HCN4 mutations

open access: yesAnnals of Pediatric Cardiology
A 35-year-old pregnant woman was referred to our hospital because of fetal bradycardia. Fetal echocardiography revealed a normal fetal heart except for slightly prominent trabeculae in the left ventricle, normal cardiac function, and fetal sinus ...
