Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

Advanced Science, EarlyView.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Assessment of asymptomatic ischemic heart disease using stress myocardial perfusion imaging in patients with type 2 diabetes mellitus

Indian Heart Journal, 2018
Background: Coronary artery disease (CAD) is the leading cause of death in patients with type 2 diabetes mellitus (T2DM) and may be asymptomatic. Objective: The objective of this study was to assess the prevalence of asymptomatic myocardial ischemia in ...

Targeting Hippocampal PTEN Suppresses Ferroptosis and Rescues Cognitive Decline in Alzheimer's Disease via Dual AKT/GSK3β/Nrf2 and AKT/STAT3 Axes

Advanced Science, EarlyView.
PTEN knockdown activates AKT phosphorylation, promoting Nrf2 nuclear translocation and STAT3 activation, which upregulates GPX4 and antioxidant enzymes HO‐1, SOD1, SOD2, and NQO1. These coordinated changes reduce lipid peroxidation and ROS, inhibit ferroptosis, and ultimately ameliorate cognitive impairment in APP/PS1 transgenic mice, highlighting a ...

Silent myocardial ischemia in patients with type 2 diabetes mellitus by a treadmill test [PDF]

, 2021
Background: Silent myocardial ischemia (SMI) is common in patients with diabetes mellitus. Coronary artery disease-related mortality is the leading cause in patients with diabetes mellitus. This can be prevented by early detection and intervention.

The role of myocardial perfusion imaging in the screening of silent ischemia in diabetic patients

Iranian South Medical Journal, 2010
Background: More than 70%of diabetes patients die from cardiovascular causes. Furthermore, consequences of coronary artery disease (CAD) are more severe ,because myocardial ischemia is often silent in these patients.

Incidence of myocardial ischemia during treatment with capecitabine: a cohort study with Holter recording and cardiac biomarkers

Acta Oncologica
Background and purpose: Treatment with fluoropyrimidines can lead to cardiotoxicity. For 5-fluorouracil, silent myocardial ischemia and effort-related myocardial ischemia have been demonstrated.

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

Advanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Silent Ischemia during PTCA: its relationship with exercise-induced silent ischemia and the possible role of beta-endorphins

, 1990
Silent myocardial ischemia can be defined as the situation during which a discrepancy occurs between O2 consumption and supply, resulting in tissue metabolic, electrical and functional alterations typical of myocardial ischemia, all in the absence of ...

Postconditioning protects against endothelial ischemia-reperfusion injury in the human forearm [PDF]

, 2006
Background: Hypoxic cell death follows interruption of blood supply to tissues. Although successful restoration of blood flow is mandatory for salvage of ischemic tissues, reperfusion can paradoxically place tissues at risk of further injury.
