Decreases in encounter rate of endangered Northeast Pacific humpback whales in Southern Costa Rica: Possible changes in migration pattern due to warming events

Frontiers in Marine Science, 2022
Warming events in the Pacific Ocean are becoming more frequent, intense, and on a larger temporal and spatial scale. This has caused critical habitats of marine species to lose their quality and marine organisms respond by modifying their critical ...

Transient Sleep Deprivation Induces Persistent Auditory Neuropathy via ROS‐Initiated Neuroinflammation and BK Channel Suppression

Advanced Science, EarlyView.
Sleep disturbance severity closely tracks hearing loss in a clinical cohort, yet the mechanistic link remains unclear. Acute sleep deprivation is shown to trigger transient cochlear oxidative stress that switches into a self‐sustaining neuroinflammatory state, suppressing BK channels and causing irreversible synaptopathy.

Case of a high flow A-V shunt associated with an extracranial vertebral-artery dissecting aneurysm treated with a flow diverter stent

Interdisciplinary Neurosurgery
Objective: Vertebrovenous fistula (VV-AVF) is a rare disease that is often caused by trauma, but occasionally associated with congenital anomalies. To date, no standardized treatment has been established, and the use of a flow diverter (FD) has been ...

ADNP‐Related Helsmoortel–Van der Aa Syndrome: A Review of the Literature and Clinical Recommendations for Assessment and Monitoring

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT ADNP‐related Helsmoortel–Van der Aa syndrome (ADNP‐related HVDAS) is a single gene form of autism spectrum disorder (ASD) caused by pathogenic sequence variants in the activity‐dependent neuroprotective protein (ADNP) gene. In addition to ASD, ADNP‐related HVDAS is associated with a wide range of cognitive, behavioral, and physical health ...

Bandwidth Improvement of EBG Resonator Antennas Using Double-Layer FSS

International Journal of Antennas and Propagation, 2008
A double-layer frequency selective surface (FSS) is proposed as a means to enhance the bandwidth of an electromagnetic band gap (EBG) resonator antenna. Due to its inverted reflection phase variation and its wide selectivity bandwidth, the structure used

Efficacy of auto-PAP titration in obstructive sleep apnea: Single-center experience

Indian Journal of Respiratory Care, 2020
Background: Obstructive sleep apnea (OSA) is a sleep-associated breathing disorder, which left untreated can cause severe morbidities or even mortality. The recommended treatment strategy for moderate-to-severe OSA is continuous positive airway pressure (

Prediction of obliteration of unruptured cerebral aneurysm by residual aneurysm volume after flow diverter stent treatment

World Neurosurgery: X
Introduction There is no methodology to predict aneurysm occlusion using residual volume after flow diverter stent treatment. We retrospectively examined whether residual aneurysm volume at 6 months postoperatively can predict the degree of aneurysm ...

The role of local renin-angiotensin system in arterial chemoreceptors in sleep-breathing disorders

Frontiers in Physiology, 2014
The renin-angiotensin system (RAS) plays pivotal roles in the regulation of cardiovascular and renal functions to maintain the fluid and electrolyte homeostasis. Experimental studies have demonstrated a locally expressed RAS in the carotid body, which is
