Prefrontal fNIRS hemodynamic correlates of attentional load during rapid serial visual presentation tasks

Frontiers in Human Neuroscience
BackgroundDespite the growing interest in functional near-infrared spectroscopy (fNIRS) for practical brain-computer interface (BCI) applications, prefrontal hemodynamic responses during rapid serial visual presentation (RSVP) tasks remain poorly ...

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

Advanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Efficacy of Granisetron on Attenuation of Hemodynamic Responses of Parturients Undergoing Elective Cesarean Delivery under Spinal Anesthesia

Archives of Anesthesia and Critical Care, 2017
Background: Maternal bradycardia and hypotension are the most common intraoperative complications after spinal anesthesia during cesarean delivery. Prophylactic administration of ondansetron has been reported to provide a protective effect. In this study

Esmolol and Lidocaine in Blunting Hemodynamic Response to Extubation

Journal of College of Medical Sciences-Nepal
Background Tracheal extubation is one of the routinely performed procedures in the practice of anaesthesiology. It has been reported that it increases heart rate and blood pressure by 15-30% lasting for 5 to 15 minutes.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Forearm blood flow and vascular conductance improve after 18 weeks of bouldering training in novice climbers

Frontiers in Sports and Active Living
BackgroundIndoor climbing can be associated with improvements in muscle strength and cardiorespiratory capacity. However, acute climbing sessions have shown to elicit an excessive hemodynamic response, and chronic vascular adaptations are still unknown ...

Copper‐Doped Prussian Blue Nanozymes With Hyaluronic Acid‐Mediated Targeting Alleviate Oxidative Stress and Regulate Cholesterol Handling for Atherosclerosis Therapy

Advanced Science, EarlyView.
CuPB@HA is a CD44‐associated, plaque‐targeted nanozyme that alleviates oxidative stress, inflammation, and lipid accumulation in macrophages. By reducing CD36‐dependent lipid uptake and promoting ABCA1/ABCG1‐mediated cholesterol handling, it improves macrophage function, preferentially accumulates in atherosclerotic lesions, reduces plaque burden, and ...
