Mapping alterations in the local synchrony of the cerebral cortex in schizophrenia

European Psychiatry, 2023
Background Observations from different fields of research coincide in indicating that a defective gamma-aminobutyric acid (GABA) interneuron system may be among the primary factors accounting for the varied clinical expression of schizophrenia.

Loss of SHP1 in Spinal Astrocytes Triggers T‐Lymphocyte Infiltration and Nociceptive Hypersensitivity

Advanced Science, EarlyView.
Astrocyte‐specific SHP1 deletion disrupts astrocyte–vascular interactions and compromises BBB integrity while enhancing STAT1‐dependent CXCL10 expression. These changes synergistically promote peripheral CD4+ and CD8+ T‐cell infiltration into the SDH. The infiltrating T cells secrete IFN‐γ, which in turn activates microglia.

The Crystal Structure Elucidation of a Tetrapeptide Analog of Somatostatin DOTA-Phe-D-Trp-Lys-Thr-OMe

Crystals, 2021
Herewith, we report for the first time the crystal structure of tetrapeptide FwKT (Phe-D-Trp-Lys-Thr), which is considered to represent an epitope for biomedically relevant hormone somatostatin.

Gestational Hypoxia Disrupts Medial Ganglionic Eminence Progenitor Dynamics and Interneuron Development in Schizophrenia

Advanced Science, EarlyView.
FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in

Systemic Bevacizumab for Severe Bleeding From Acquired Gastrointestinal Vascular Malformations

American Journal of Hematology, EarlyView.
Targeted antiangiogenic therapy with systemic bevacizumab for bleeding from acquired GI VMs was found to be safe and effective for chronic and severe bleeding from acquired vascular malformations due to idiopathic angiodysplasia, chronic liver disease, and deficiencies of von Willebrand factor, in a patient population comprised mostly of heavily ...

North American Delphi Consensus Study on Sinonasal Malignancy Survivorship Care

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Survival for patients with sinonasal cancers has improved over the past decades, but there are no dedicated survivorship guidelines for this cohort. Objective To understand experts’ priorities and perspectives on key survivorship tenets (surveillance, second tumor screening, toxicity, and symptom management).

Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.
