Oxytocin Reduces Subjective Fear in Naturalistic Social Contexts via Enhancing Top‐Down Middle Cingulate Amygdala Regulation and Brain‐Wide Fear Representations

open access: yesAdvanced Science, EarlyView.
This double‐blind, placebo‐controlled study demonstrates that intranasal oxytocin reduces subjective fear in immersive, naturalistic social (but not non‐social) contexts. Concomitant fMRI reveals that oxytocin enhances middle cingulate activity and amygdala connectivity while it modulates network‐level connectivity and attenuates reactivity of a brain ...

Astrocytic ET‐1 System Determines Microglia Phenotype Following Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
The study reveals that astrocytic ET‐1 system is solely activated by thrombin following SCI via RhoA/NF‐κB and MAPKs/NF‐κB signal pathway. The release of astrocytic ET‐1 drives microglia polarization toward M1 phenotype through YAP signaling via ETA and ETB receptors.

The Multifaceted Etiology of Mental Disorders With a Focus on Trace Elements, a Review of Recent Literature

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Mental disorders are a significant global public health concern, affecting nearly one in eight individuals worldwide. This review investigates the multifaceted etiology of mental disorders—specifically major depressive disorder (MDD), schizophrenia (SCZ), and bipolar disorder (BD)—through genetic, neurobiological, and environmental ...

3‐Year Outcomes of Temperature‐Controlled Radiofrequency Ablation of the Posterior Nasal Nerve in Patients With Chronic Rhinitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Temperature‐controlled radiofrequency (TCRF) ablation of the posterior nasal nerve has been shown to improve chronic rhinitis (CR) symptoms and quality of life (QoL). This study assesses the durability of TCRF's effectiveness and safety 3 years post‐procedure in patients with perennial allergic CR and nonallergic CR.

A Drosophila model of prion disease and its metabolic changes in the brain

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We developed a Drosophila model for prion disease, and flies were capable of expressing the hamster prion protein (HaPrP) under the control of the GAL4/UAS system. The model exhibited some characteristics of the disease in mammals and displayed alterations in protein, sphingolipid, and carbohydrate metabolism. Preliminary applications have demonstrated

Structural analysis of the starfish SALMFamide neuropeptides S1 and S2: The N-terminal region of S2 facilitates self-association [PDF]

open access: yes, 2014
The neuropeptides S1 (GFNSALMFamide) and S2 (SGPYSFNSGLTFamide), which share sequence similarity, were discovered in the starfish Asterias rubens and are prototypical members of the SALMFamide family of neuropeptides in echinoderms.

μ‐Opioid Receptor Dynamics in the Parameningeal Tissue During Migraine Attacks

open access: yesAnnals of Neurology, EarlyView.
Objective The possible impact of meningeal μ‐opioid receptor (μOR) binding in migraine remains unknown. This study investigated μOR availability in the cranial parameninges involved in migraine initiation via nociceptor activation. Methods We used positron emission tomography with [11C] carfentanil, and measured μOR availability in meninges and ...

NPY Levels In Type 1 Diabetic Men of Different Duration. [PDF]

open access: yes, 2011
Background: The aim of the present study was to evaluate whether the different duration of type 1 diabetes mellitus influences basal NPY secretion. Design: The NPY concentrations were measured in sixty-eight men with insulin-dependent diabetes mellitus ...

Nuclear parcellation of pontine catecholaminergic and cholinergic neurons in gray parrots and pied crow brains

open access: yesThe Anatomical Record, EarlyView.
Immunohistochemical staining for tyrosine hydroxylase reveals the neurons forming the locus coeruleus complex in the pontine region of the brain of the Congo gray parrot. The appearance and parcellation of the locus coeruleus complex in birds shows many similarities, but also differences to that observed in mammals.
