Temporal‐Targeted Accelerated 40 Hz tACS Enhances Cognitive Function and Network Integration in Alzheimer's Disease: A Randomized Clinical Trial

open access: yesAdvanced Science, EarlyView.
Bilateral temporal accelerated 40‐Hz tACS improves cognitive function in patients with Alzheimer's disease. Resting‐state fNIRS identifies treatment‐related increases in frontotemporoparietal functional connectivity, which are associated with cognitive improvement. ABSTRACT The temporal lobes are key hubs for memory and cognition.

A Facial Foundation Model for Clinical Biomarker Prediction and Real‐World Mobile Deployment

open access: yesAdvanced Science, EarlyView.
MedicalFaceFound is a facial foundation model developed through three‐stage progressive pre‐training, adapting representations from general vision to facial structure and clinical phenotypes. Using a single facial image, it estimates 62 biomarkers across multiple physiological systems and supports downstream risk prediction for cardiovascular ...

Identification of the Hb Lepore phenotype by HPLC

open access: yesHaematologica, 1999
BACKGROUND AND OBJECTIVE: Hb Lepore is a structurally abnormal hemoglobin in which the abnormal globin chain is a hybrid or fused globin chain (db). Three different Lepore hemoglobins have been identified, differing from each other in the point at which ...

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Overcoming tumor hypoxia as a barrier to radiotherapy, chemotherapy and immunotherapy in cancer treatment

open access: yesInternational Journal of Nanomedicine, 2018
Kaitlin Graham, Evan Unger NuvOx Pharma, Tucson, AZ, USA Abstract: Hypoxia exists to some degree in most solid tumors due to inadequate oxygen delivery of the abnormal vasculature which cannot meet the demands of the rapidly proliferating cancer cells.

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

open access: yesAdvanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Engineered Peptide Self‐Assembled Nanofibers for Enhanced STING Activation: A Promising Nanodelivery Platform for Immunotherapy of Pediatric Solid Tumors

open access: yesAdvanced Science, EarlyView.
An engineered peptide self‐assembled nanofiber platform, designed to replicate STING–cGAMP binding motifs, facilitates pH‐responsive cytosolic delivery of cGAMP, enhances the endoplasmic reticulum with high efficiency, and robustly activates the STING pathway.

Drug Repurposing for Treating NCOR‐Related Intellectual Disability

open access: yesAdvanced Science, EarlyView.
An autism‐associated NCOR1 heterozygous mutation upregulates NRGs and activates NRG backward signaling in hypothalamic GABAergic neurons in mouse models, leading to Gabra2 downregulation and cognitive deficits, which can be therapeutically targeted by repurposing FDA‐approved drugs.

Abnormalities of hemoglobin A₂

open access: yes, 1969
Hereditary abnormalities of the A. fraction of human hemoglobin may be: (a) structural, in which a genetically determined change in the amino acid composition and sequence of either the alpha or the delta polypetide chains, results in the production of a hemoglobin A variant and (b) quantitative, in which changes in concentration in the hemoglobin A₂ ...
