A cascade model of dynamic cerebral autoregulation

The Journal of Physiology, EarlyView.
Abstract figure legend This study examined a two‐component cascade model linking upstream dynamic cerebral autoregulation (dCA) with downstream microvascular function (MF) to explain how blood pressure oscillations influence cortical oxygenation. Transfer function analysis in the frequency domain was applied to quantify H1(f) (MAP→CBFV; dCA), H2(f ...

SSTMNet: Spectral-Spatio-Temporal and Multiscale Deep Network for EEG-Based Motor Imagery Classification

Mathematics
Motor impairment is a critical health issue that restricts disabled people from living their lives normally and with comfort. Detecting motor imagery (MI) in electroencephalography (EEG) signals can make their lives easier.

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

Extraction and Coordination Chemistry of Mo(Ⅵ)/U(Ⅵ) With Unilateral Derivatized Phenanthroline Amide Ligands

He huaxue yu fangshe huaxue
Medical radioactive isotopes play a very important role in disease diagnosis and treatment, with 99Tcm drugs being widely used in disease diagnosis. 99Tcm is primarily obtained from its parent nuclide, 99Mo, through a 99Mo/99Tcm generator. Currently, the

EEG‐Based Cortical Alterations in Patients Following Total Hip and Knee Arthroplasty Due to Osteoarthritis: Pre‐ and Post‐Operative Assessment

Brain and Behavior, Volume 16, Issue 5, May 2026.
This study reveals significant neuroplastic changes in cortical EEG activity post total hip/knee arthroplasty in osteoarthritis patients, with increased low alpha and theta power over frontocentral/parietal regions during rest and motor imagery. These alterations accompany functional improvements (HHS/KSS), suggesting qEEG's potential for monitoring ...

T2$$ {\boldsymbol{T}}_{\mathbf{2}} $$‐Weighted Imaging of Water, Fat and Silicone

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2765-2775, May 2026.
ABSTRACT Purpose Magnetic resonance imaging (MRI) is a sensitive method for assessing silicone implant integrity, with T2$$ {T}_2 $$‐weighted imaging being essential for detecting abnormalities in surrounding tissue. Silicone breast imaging protocols often require multiple tailored sequences for species suppression and diagnostic contrast. We propose a

Harmonic and power spectrum analysis of vertical ground reaction force in patients who have a stroke within 3 months

Experimental Physiology, Volume 111, Issue 5, Page 2528-2542, 1 May 2026.
Abstract Stroke remains a primary cause of disability globally. An in‐depth comprehension of gait impairments following a stroke is vital for crafting effective therapeutic interventions, and vertical ground reaction forces (vGRF) provide valuable insights into these mechanics.

Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated a trans‐Pacific tsunami. The hypocenter was nearly at the same location as the 1952 great earthquake (Mw 8.8–9.0). Determining whether the 2025 rupture reached the trench and how it relates to the 1952 event is crucial for understanding slip behavior along the Kamchatka subduction zone. We

Delamination and Scrolling of the Phyllosilicate Kenyaite

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 6, 07 April 2026.
Kenyaite was delaminated via cation exchange with meglumine. Nanosheets of 1.6 nm thickness are initially locked in a coplanar arrangement but scroll up upon dilution. Kenyaite, Na[Si10O20(OH)] · 4H2O, is a phyllosilicate structurally related to Ilerite and Magadiite, whose platy, nonintergrown morphology makes it a promising precursor for high‐aspect ...

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety

Advanced Science, Volume 13, Issue 24, 27 April 2026.
This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...
