Authors:
S Arcari M Moscati

Eur J Paediatr Dent 2018 Sep;19(3):205-212

Private practice, Rome, Italy.

Aim: Pain experienced during dental treatment increases the risk of developing dental anxiety in children who will became anxious adults, avoiding dental care. It is therefore essential to provide pain-free dental treatment. The strongest fears are often associated with injections: being able to successfully complete painless restorative treatment without the need for local anesthesia injection is therefore an important goal.

The Spatial-Temporal Characteristics and Influential Factors of NOx Emissions in China: A Spatial Econometric Analysis.

Int J Environ Res Public Health 2018 07 4;15(7). Epub 2018 Jul 4.

School of Economics and Management, China University of Geosciences, 388 Lumo Road, Wuhan 430074, China.

While the progress of China’s industrialization and urbanization has made great strides, atmospheric pollution has become the norm, with a wide range of influence and difficult governance. While many previous works on NOx pollution have been developed from the perspectives of natural science and technology, few studies have been conducted from social-economic points of view, and regional differences have not been given adequate attention in driving force models. This paper adopts China’s provincial panel data from 2006 to 2015, an extended STIRPAT (Stochastic Impacts by Regression on Population, Affluence and Technology) model, and spatial econometric models to investigate the socio-economic influential factors and spatial-temporal patterns of NOx emissions.

Results, meta-analysis and a first evaluation of UR, the urinary nitrate-to-nitrite molar ratio, as a measure of nitrite reabsorption in experimental and clinical settings.

Amino Acids 2018 Jul 4;50(7):799-821. Epub 2018 May 4.

Institute of Clinical Biochemistry, Hannover Medical School, Hannover, Germany.

We recently found that renal carbonic anhydrase (CA) is involved in the reabsorption of inorganic nitrite (NO), an abundant reservoir of nitric oxide (NO) in tissues and cells. Impaired NO synthesis in the endothelium and decreased NO bioavailability in the circulation are considered major contributors to the development and progression of renal and cardiovascular diseases in different conditions including diabetes. Isolated human and bovine erythrocytic CAII and CAIV can convert nitrite to nitrous acid (HONO) and its anhydride NO which, in the presence of thiols (RSH), are further converted to S-nitrosothiols (RSNO) and NO.

Protocol for a double blind, randomised placebo-controlled trial using ondansetron to reduce vomiting in children receiving intranasal fentanyl and inhaled nitrous oxide for procedural sedation in the emergency department (the FON trial).

BMJ Paediatr Open 2018 24;2(1):e000218. Epub 2018 Jan 24.

Emergency Department, The Royal Children's Hospital, Melbourne, Australia.

Introduction: Intranasal fentanyl and nitrous oxide (NO) can be combined to create a non-parenteral procedural sedation regimen for children in the paediatric emergency department. This combination of intranasal fentanyl and NO provides effective pain relief for more painful procedures, but is associated with a higher incidence of vomiting than NO alone. Our aim is to assess whether ondansetron used preventatively reduces the incidence of vomiting associated with intranasal fentanyl and NO for procedural sedation compared with placebo. Read More

A physiologically based model for denitrogenation kinetics.

Med Gas Res 2017 Oct-Dec;7(4):256-259. Epub 2018 Jan 22.

Medical R&D, Air Liquide Santé International, Centre de Recherche Claude-Delorme, Jouy-en-Josas, France.

Under normal conditions we continuously breathe 78% nitrogen (N) such that the body tissues and fluids are saturated with dissolved N. For normobaric medical gas administration at high concentrations, the N concentration must be less than that in the ambient atmosphere; therefore, nitrogen will begin to be released by the body tissues. There is a need to estimate the time needed for denitrogenation in the planning of surgical procedures. Read More

Polyphenols in Kuding tea help prevent HCl/ethanol-induced gastric injury in mice.

Food Funct 2018 Mar 27;9(3):1713-1725. Epub 2018 Feb 27.

Chongqing Collaborative Innovation Center for Functional Food, Chongqing University of Education, Chongqing 400067, P.R. China. and Department of Food Science and Biotechnology, Cha University, Seongnam, Gyeonggi 13488, Korea.

We conducted the present study to determine the gastric injury preventive effects of polyphenols in Kuding tea (KTPs) in Kunming (KM) mice through the inhibition of gastric-acid secretion and the protection of the gastric mucosa. Mice treated with a high concentration of Kuding tea polyphenols (HKTP) had lower serum levels of interleukin-6 (IL-6), IL-12, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), motilin (MOT), substance P (SP), and endothelin-1 (ET-1), and higher serum levels of somatostatin (SS) and vasoactive intestinal peptide (VIP) than did the mice in the control group. Serum and gastric tissue levels of nitrous oxide (NO), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and GSH were higher in the HKTP-treated mice than in the control mice, but malondialdehyde (MDA) levels were lower in the HKTP-treated mice than in the control mice.

A Rare Case of Intermittent Claudication Associated with Impaired Arterial Vasodilation.

Case Rep Vasc Med 2017 24;2017:4868123. Epub 2017 Dec 24.

Department of Sports Medicine, Máxima Medical Centre, Veldhoven, Netherlands.

Exercise-related intermittent claudication is marked by reduced blood flow to extremities caused by either stenosis or impaired vascular function. Although intermittent claudication is common in the elderly, it rarely occurs in the young and middle-aged individuals. Here, we report a case of exercise-related claudication in a 41-year-old woman, in the absence of overt vascular pathology. Read More

Intranasal drug administration for procedural sedation in children admitted to pediatric Emergency Room.

Eur Rev Med Pharmacol Sci 2018 Jan;22(1):217-222

Department of Pediatrics, Catholic University of The Sacred Heart, School of Medicine Gemelli Hospital Foundation, Rome, Italy.

Objective: Pain relief is a very important aspect in Pediatrician's clinical practice. It is often thought that young children, particularly infants, do not perceive as much pain as adults because of their immature nervous system and that untreated pain would not have adverse long-term consequences. Instead, it has been demonstrated that infants and children experience pain in a similar manner to adults. Read More

Recording Brain Electromagnetic Activity During the Administration of the Gaseous Anesthetic Agents Xenon and Nitrous Oxide in Healthy Volunteers.

J Vis Exp 2018 01 13(131). Epub 2018 Jan 13.

Centre for Human Psychopharmacology, Swinburne University of Technology;

Anesthesia arguably provides one of the only systematic ways to study the neural correlates of global consciousness/unconsciousness. However to date most neuroimaging or neurophysiological investigations in humans have been confined to the study of γ-Amino-Butyric-Acid-(GABA)-receptor-agonist-based anesthetics, while the effects of dissociative N-Methyl-D-Aspartate-(NMDA)-receptor-antagonist-based anesthetics ketamine, nitrous oxide (N2O) and xenon (Xe) are largely unknown. This paper describes the methods underlying the simultaneous recording of magnetoencephalography (MEG) and electroencephalography (EEG) from healthy males during inhalation of the gaseous anesthetic agents N2O and Xe.

Exploring Nitrous Oxide as Treatment of Mood Disorders: Basic Concepts.

J Clin Psychopharmacol 2018 Apr;38(2):144-148

Nitrous oxide (laughing gas) has shown early promise as a rapidly acting antidepressant in patients with treatment-resistant major depression and is currently investigated in several clinical trials. Because nitrous oxide is rarely administered outside operating rooms or dental practices, most psychiatrists are not familiar with how nitrous oxide is administered in a medical setting and what regulations guide its use. The goal of this brief review was to educate psychiatrists about the basic concepts of nitrous oxide administration and pharmacology. Read More

MAC-sparing effect of nitrous oxide in sevoflurane anesthetized sheep and its reversal with systemic atipamezole administration.

PLoS One 2018 9;13(1):e0190167. Epub 2018 Jan 9.

Department of Clinical Studies-New Bolton Center, University of Pennsylvania, School of Veterinary Medicine, Kennett Square, Pennsylvania, United States of America.

Introduction: Nitrous oxide (N2O) is an anesthetic gas with antinociceptive properties and reduces the minimum alveolar concentration (MAC) for volatile anesthetic agents, potentially through mechanisms involving central alpha2-adrenoceptors. We hypothesized that 70% N2O in the inspired gas will significantly reduce the MAC of sevoflurane (MACSEVO) in sheep, and that this effect can be reversed by systemic atipamezole.

Materials And Methods: Animals were initially anesthetized with SEVO in oxygen (O2) and exposed to an electrical current as supramaximal noxious stimulus in order to determine MACSEVO (in duplicates). Read More
