[PMID: 32414698 DOI: 10.1016/j.oooo.2020.02.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 01/26/2020] [Accepted: 02/08/2020] [Indexed: 02/08/2023]
Abstract
OBJECTIVE The aim of this study was to unveil the reciprocal relation of tumor characteristics and inflammation in inflammatory myofibroblastic tumor in the head and neck. STUDY DESIGN The study included a retrospective cohort of patients with inflammatory myofibroblastic tumors treated between 2005 and 2017 in a tertiary hospital. Tumor features and inflammation were assessed through the expression of anaplastic lymphoma kinase (ALK), the degree of inflammation and cyclooxygenase-2 (COX-2) expression. The prognostic factors were analyzed for overall survival (OS) and disease-free survival (DFS) in univariate and multivariate analyses. RESULTS Forty-one patients diagnosed with inflammatory myofibroblastic tumors were followed up, and 41 paraffin sections were obtained. The positive rate of ALK expression was 21 (51.2%) of 41 patients. Nineteen patients had high-grade ALK expression, and 22 patients had low-grade ALK expression. Thirty-nine patients had high-grade inflammation, and 2 had low-grade inflammation. The positive rate of COX-2 expression was 100%. Tumors with both high-grade ALK expression and inflammation had worse DFS (P = .015). The multivariate Cox analysis showed that the grades of ALK expression and inflammation (P = .004) were independent risk factors for DFS. CONCLUSIONS Because of the latent synergistic effects of ALK and inflammation in the tumorigenesis of inflammatory myofibroblastic tumor, the combined therapy of ALK and COX-2 inhibitors shows promise.

Abstract
Compounds 1-14 were synthesized in a search for high-affinity CRF1 receptor ligands that could be radiolabeled with (11)C or (18)F for use as positron emission tomography (PET) radiotracers. Derivatives of 2 were developed which contained amide N-fluoroalkyl substituents. Compounds [(18)F]24 and [(18)F]25 were found to have appropriate lipophilicities of logP7.4=2.2 but microPET imaging with [(18)F]25 demonstrated limited brain uptake.

Abstract
Corticotropin-releasing factor (CRF) coordinates the neural, endocrine and immune responses of the body to stress. Therefore, CRF receptors are important targets for the design of drugs for depression, anxiety and stress-related disorders. Several laboratories have published extensive preclinical and limited clinical research into the role of CRF in human disease. This review covers developments in the patent literature during 2002 - 2006 and outlines the prospects for CRF-based therapy for mental illness.

Abstract
INTRODUCTION The ventromedial hypothalamus (VMH) controls female rodent copulatory behavior, which can be modulated by injection of various compounds into the VMH. Aim. The aim was to determine whether evoked excitatory postsynaptic potentials (EPSPs) or single-unit activity within the VMH ex vivo is a better parameter to predict lordosis. METHODS VMH slices were placed onto a 64 microelectrode chip and spontaneous single-unit activity was recorded or slices stimulated to evoke EPSPs. MAIN OUTCOME MEASURES The sodium channel blocker, tetrodotoxin and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate antagonist, 6,7-dinitroquinoxaline-2,3-dione (DNQX) inhibited EPSPs, confirming EPSPs were glutamatergic in origin. The GABA(A) antagonist bicuculline potentiated EPSPs implying endogenous GABA tone. Single-unit activity was abolished by tetrodotoxin but unaffected by DNQX or bicuculline. RESULTS Glutamatergic neurotransmission was greatest during metestrous and following ovariectomization. The number of regions within the VMH eliciting single-unit activity was reduced following ovariectomy without changing spike frequency. Adrenergic agents increasing lordosis via the VMH in vivo, decreased glutamate neurotransmission but increased single-unit activity. Conversely, agents decreasing lordosis via the VMH increased glutamatergic neurotransmission and inhibited single-unit activity (8-OH-DPAT, [D-Ala(2), N-Me-Phe(4), Gly-ol(5)]-enkephalin, corticotropin releasing factor, bicuculline). Melanocortin and pituitary adenylate cyclase-activating polypeptide agonists had no effect. CONCLUSIONS Here we present a novel, robust VMH in vitro technique that (i) is consistent with the hypothesis that glutamate via non-NMDA receptors inhibits lordosis; (ii) glutamate is under the endogenous tone of GABA and steroid hormones; (iii) inhibition of lordosis during metestrous and following ovariectomy potentiates glutamatergic neurotransmission; (iv) activation of G(q)- and G(i)-coupled receptors decreases and increases glutamate neurotransmission, respectively, with an inverse correlation on single-unit activity; (v) activation of G(s)-coupled receptors has no direct effect on glutamate or single-unit activity; and (vi) potency, receptor subtypes and localization can be determined prior to in vivo studies.

Abstract
INTRODUCTION Neuropeptides are known to modulate female receptivity. However, even though receptivity is a spinal reflex, the role of neuropeptides within the spinal cord remains to be elucidated. AIM The aims were to (i) investigate neuropeptides in the lumbosacral region; and (ii) determine how neuropeptides modulate glutamate release from stretch Ia fibers, touch sensation Abeta fibers and Adelta/C pain fibers. MAIN OUTCOME MEASURES Neuropeptide modulation of the lumbosacral dorsal-root ventral-root reflex in vitro. METHODS Spinal cords were removed from Sprague-Dawley rats in compliance with UK Home Office guidelines. Hemisected cords were superfused with aCSF and the dorsal root (L4-S1) was stimulated to evoke glutamate release. A biphasic reflex response was evoked from the opposite ventral root consisting of a monosynaptic (Ia fibers) and polysynaptic (Abeta, Adelta/C fibers) component. RESULTS The micro opioid receptor (MOR) agonist DAMGO inhibited the monosynaptic (EC(50) 0.02 +/- 0.02 nM) and polysynaptic area (EC(50) 125 +/- 167 nM) but not polysynaptic amplitude. Oxytocin and corticotrophin releasing factor (CRF) inhibited the monosynaptic amplitude (EC(50), 1.4 +/- 1.0 nM and EC(50) 4.3 +/- 3.5 nM, respectively), polysynaptic amplitude (EC(50) 18.2 +/- 28.0 nM and EC(50), 9.5 +/- 13.3 nM, respectively), and area (EC(50) 11.6 +/- 13.0 nM and EC(50), 2.8 +/- 3.3 nM, respectively); effects that were abolished by oxytocin and CRF(1) antagonists, L-368899 and 8w. Melanocortin agonists solely inhibited the monosynaptic component, which were blocked by the MC(3/4) receptor antagonist SHU9119. CONCLUSION These data suggest endogenous neuropeptides are released within the lumbosacral spinal cord. Melanocortin agonists, oxytocin, CRF, and DAMGO via MC(4), oxytocin, CRF(1), and MOR inhibit glutamate release but with differing effects on afferent fiber subtypes. Melanocortins, oxytocin, CRF, and DAMGO have the ability to modulate orgasm whereas oxytocin, CRF and DAMGO can increase pain threshold. Oxytocin and CRF may dampen touch sensation.

Abstract
The CRF antagonist pharmacophore is a heterocyclic ring bearing a critical hydrogen-bond acceptor nitrogen and an orthogonal aromatic ring. CRFR1 antagonists have shown a 40-fold and 200-fold loss in potency against the CRFR1 H199V and M276I mutant receptors, suggesting key interactions with these residues. We have derived a two component computational model that correlates CRFR1 binding affinity within the reported series to antagoinst/H199 complexation energy and M276 hydrophobic contacts.
