A Hypoxia‐Responsive Single‐Atom Sonozyme for Targeted Sonocatalytic Therapy in Alleviating Atherosclerotic Plaque

open access: yesAdvanced Science, EarlyView.
A tetranitrogen‐coordinated single‐atom manganese catalyst (SMC) is fabricated with outstanding sonosensitization efficiency and multi‐enzyme‐like catalytic properties. To enable better targeting of M1 macrophages, hyaluronic acid (HA) is applied to modify the surface of SMC, yielding SMC‐HA nanozymes.

Targeted Delivery of CNS‐Specific Hesperidin as a Leptin Sensitizer for Treating Obesity‐Associated Sleep‐Disordered Breathing

open access: yesAdvanced Science, EarlyView.
Hesperidin nanoparticles (HE NPs) effectively combat obesity and sleep‐disordered breathing in mice by enhancing leptin sensitivity. Through suppression of hypothalamic endoplasmic reticulum stress and restoration of leptin signaling, HE NPs promote weight loss and improve breathing during sleep.

Echographic features of the structure of atherosclerotic plaques in carotid ischemic stroke

open access: yesНеврология, нейропсихиатрия, психосоматика, 2020
An assessment of not only the degree of stenosis, but also the structure of atherosclerotic plaques (ASPs) in the carotid arteries can reveal atheromas that are dangerous for the development of cerebrovascular events in asymptomatic individuals.Objective:

Determination of wave intensity in flexible tubes using measured diameter and velocity [PDF]

open access: yes, 2007
Wave intensity (WI) is a hemodynamics index, which is the product of changes in pressure and velocity across the wave-front. Wave Intensity Analysis, which is a time domain technique allows for the separation of running waves into their forward and ...

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Recovery from repeated sudden hearing loss in a patient with Takayasu’s arteritis treated with hyperbaric oxygen therapy: the first report in the literature [PDF]

open access: yes, 2017
Hearing loss has been rarely reported in Takayasu's arteritis, presents as sudden sensorineural hearing loss and usually responds well to corticosteroid therapy.

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

open access: yesAdvanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...

Ultrasound screening for asymptomatic carotid stenosis in subjects with calcifications in the area of the carotid arteries on panoramic radiographs: a cross-sectional study

open access: yesBMC Cardiovascular Disorders, 2011
Background Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic ...
