A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

open access: yesAdvanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

open access: yesAdvanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

Modulation of Presynaptic Inhibitory Retinal Circuits for Retinal Ganglion Cell Neuroprotection in Glaucoma

open access: yesAdvanced Science, EarlyView.
Ocular hypertension induces early hyperactivity in inner retinal inhibitory circuitry before substantial retinal ganglion cell loss. Sustained pharmacological inhibition of GABAergic/glycinergic neurotransmission and Vgat‐targeted Lin28 expression suppress this hyperactivity and improve RGC survival without reducing intraocular pressure. These findings

Mirabegron escalation to 50 mg further improves daily urgency and urgency urinary incontinence in Asian patients with overactive bladder

open access: yesJournal of the Formosan Medical Association, 2019
Purpose: To investigate the efficacy and safety of mirabegron dose escalation from 25 to 50 mg in Asian patients with overactive bladder (OAB). Methods: A total of 242 patients (mean age: 67 years) with OAB were randomized to two groups: M25 (mirabegron ...

Beta-adrenergic agonists increase amplitude of LH release in orchidectomized rats

open access: yes, 1986
The role of intravenously (iv) injected adrenergic agonists in the pulsatile secretion of luteinizing hormone (LH) was examined in unanesthesized, freely behaving, castrated male rats. The alpha 2-adrenergic receptor agonist, clonidine (25 micrograms/kg)

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

open access: yesAdvanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Novel mutants of the human beta(1)-adrenergic receptor reveal amino acids relevant for receptor activation

open access: yes, 2006
Activation of G protein-coupled receptors like the beta(1)-adrenergic receptor results in conformational changes that ultimately lead to signal propagation through a G protein to an effector like adenylyl cyclase.

Non‐Invasive Assessment of Perineural Invasion Density: A Novel Marker for Prognosis and Treatment Stratification in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
This study establishes perineural invasion density (PNID) as a superior prognostic marker in prostate cancer, outperforming conventional perineural invasion in predicting biochemical recurrence and radiographic progression. Concurrent β–blocker use is associated with favorable outcomes exclusively in High–PNID patients. An MRI–based deep learning model

Perspectives of drug treatment of obesity [PDF]

open access: yesEinstein (São Paulo), 2006
The perspectives in the pharmacological treatment of obesitycan be classified in two classes: drugs already in the market,in advanced clinical trial or in final approval, or drugs in earlydevelopment.
