Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

open access: yesAdvanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

Neuroprotective effects of carnitinoid compounds in rodent cellular and in vivo models of mitochondrial complex I dysfunction [PDF]

open access: yes, 2019
Rotenone-mediated mitochondrial complex I inhibition was used to model Parkinson’s disease-like syndrome in Lewis rats. Tyrosine hydroxylase immunolabeling demonstrated a decrease in the number of dopaminergic neurons as well as aberrant morphology in ...

Influence of age on outcome from thrombolysis in acute stroke: a controlled comparison in patients from the Virtual International Stroke Trials Archive (VISTA) [PDF]

open access: yes, 2010
<p><b>Background and Purpose:</b> Thrombolysis for acute ischemic stroke in patients aged >80 years is not approved in some countries due to limited trial data in the very elderly.

Nasal Delivery of Engineered Exosomes via a Thermo‐Sensitive Hydrogel Depot Reprograms Glial Cells for Spinal Cord Repair

open access: yesAdvanced Science, EarlyView.
Engineered macrophage‐derived exosomes overexpressing GNA12 and GNA13 reprogram glial cells to promote neuroprotection and neural regeneration following SCI. A chitosan‐based thermosensitive hydrogel enables sustained intranasal exosome delivery, bypassing systemic barriers and enhancing therapeutic efficacy.

Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling

open access: yesAdvanced Science, EarlyView.
The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

Glymphatic and lymphatic communication with systemic responses during physiological and pathological conditions in the central nervous system

open access: yesCommunications Biology
Crosstalk between central nervous system (CNS) and systemic responses is important in many pathological conditions, including stroke, neurodegeneration, schizophrenia, epilepsy, etc.

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

5-HIAA induces neprilysin to ameliorate pathophysiology and symptoms in a mouse model for Alzheimer’s disease

open access: yesActa Neuropathologica Communications, 2018
Serotoninergic activation which decreases brain Aβ peptides is considered beneficial in mouse models for Alzheimer’s disease (AD), but the mechanisms involved remain unclear.

Potassium channel activators protect the N-methyl-D-aspartate-induced cerebral vascular dilation after combined hypoxia and ischemia in piglets [PDF]

open access: yes, 1998
Background and Purpose-Cerebral arteriolar dilation to N-methyl-D-aspartate (NMDA) is a neuronally mediated multistep process that is sensitive to cerebral hypoxia and ischemia (H/I).
