Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

open access: yesAdvanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

open access: yesAdvanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Prolonged hypoperfusion and early stroke after transient ischemic attack.

open access: yes, 1990
Many patients suffer a stroke early after a transient ischemic attack, but the reason why is often unclear. We studied 12 patients with less than 75% stenosis of the internal carotid artery and a single hemispheric transient ischemic attack lasting less ...

Galactokinase 1 Positively Regulates Mitochondrial Respiration by Phosphorylating TIMM13 as a Protein Kinase

open access: yesAdvanced Science, EarlyView.
GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Clinical utility of pharyngeal high‐resolution manometry with impedance for upper esophageal sphincter dysfunction in gastroenterology

open access: yesAdvances in Digestive Medicine, EarlyView.
Abstract Pharyngeal high‐resolution manometry with impedance (P‐HRM‐I) is an established assessment method used to evaluate pharyngeal swallowing. It provides precise quantification of swallowing biomechanics that enable the detection of alterations in swallowing physiology.

''Neuroprotective effect of transient ischemic attack''

open access: yes, 2011
International audience''Transient ischemic attack (TIA) is a well-recognized risk factor of ischemic stroke. Hence, 7 to 25% of ischemic stroke patients have a history at TIA, and the risk of ischemic stroke after TIA is about 15% at 3 months.

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Blood Biomarkers of Alzheimer's Disease and Patterns of Structural Brain Changes in the Community

open access: yesAnnals of Neurology, EarlyView.
Objective We aimed to investigate the associations between Alzheimer's disease (AD)‐related blood biomarkers and changes in brain volumes and cerebrovascular burden in community‐dwelling older adults. Methods We included 361 dementia‐free participants with a Mini‐Mental State Examination (MMSE) score ≥ 27 and without prior cerebrovascular events from a
