Palatable‐Food–Driven Top‐Down Circuit Inhibits PVNCRF Activity to Mitigate Stress Via Peri‐PVNCRFR1 Neurons

Advanced Science, EarlyView.
Palatable food alleviates stress and prevents anxiety. This study uncovers a dedicated neural pathway: dopamine release in the PFC activates D1R neurons, whose projections to the peri‐PVN engage a population of anxiolytic CRFR1 neurons. These neurons then inhibit stress‐induced hyperactivity of PVNCRF neurons, providing a circuit‐level explanation for ...

An Anterior Cingulate Cortex‐Anterior Insular Cortex Glutamatergic Circuit Gates Stress‐Induced Visceral Hypersensitivity and Anxiety via Ionotropic Glutamate Receptors Trafficking

Advanced Science, EarlyView.
This study identifies an anterior cingulate cortex (ACC) to anterior insular cortex (AIC) glutamatergic (Glu) circuit that gates stress induced visceral hypersensitivity and anxiety. Circuit activation induces both phenotypes, whereas inhibition relieves them.

Uveal melanoma dissemination within the scleral tract in fine needle aspiration biopsy

Офтальмохирургия, 2021
Introduction. Fine needle aspiration biopsy (FNAB) of uveal melanoma (UM) is an invasive procedure. Many authors consider UM FNAB to be safe procedure, however extraocular extension of the tumor through the scleral tracts may occur.

Permanent Rumen Cannula

Journal of Dairy Science, 1969
Abstract A permanent rumen cannula for use in fistulated cattle is described. The cannula is constructed of acrylic resin and consists of the main stem, inner and outer rings, cap, and a polyurethane collar or cushion of a pliable nature. The main stem is threaded to accommodate a screw cap and to permit adjustment of the outer ring according to the ...

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, EarlyView.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

Rox Index Dynamics According to High Flow Nasal Cannula Success in Intensive Care Unit Patients with COVID-19-Related Acute Respiratory Failure

Balkan Medical Journal, 2023
Background: High-flow nasal cannula therapy has been shown to be useful in the treatment of patients with acute respiratory failure caused by severe acute respiratory syndrome-coronavirus disease-2. The ROX index can help predict the success of high-flow

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

Advanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...
