Impedance pH Monitoring: Intra-observer and Inter-observer Agreement and Usefulness of a Rapid Analysis of Symptom Reflux Association.

Journal of neurogastroenterology and motility

Tenca A, Campagnola P, Bravi I, Benini L, Sifrim D, Penagini R.
PMID: 24840372
J Neurogastroenterol Motil. 2014 Apr 30;20(2):205-11. doi: 10.5056/jnm.2014.20.2.205.

BACKGROUND/AIMS: Symptom reflux association analysis is especially helpful for evaluation and management of proton pump inhibitor (PPI) re-fractory patients. An accurate calculation requires manual editing of 24-hour multichannel intraluminal impedance-pH (MII-pH) tracings after automatic analysis. Intra- and inter-observer agreement...

Photofragmentation of dichloromethanol Cl2CHOH along C-O and C-Cl cleavages: a theoretical study.

Photochemistry and photobiology

Mühlhäuser M, Schnell M, Peyerimhoff SD.
PMID: 12194214
Photochem Photobiol. 2002 Aug;76(2):176-80. doi: 10.1562/0031-8655(2002)076<0176:podcca>2.0.co;2.

Multireference configuration interaction calculations are carried out for ground and excited states of dichloromethanol, Cl2CHOH, to investigate two important photofragmentation processes relevant to atmospheric chemistry. Five low-lying excited states (1(1)A", 2(1)A', 1(3)A", 2(3)A" and 1(3)A') in the energy range...

Production of singlet oxygen atoms by photodissociation of oxywater.

The Journal of chemical physics

Franz J, Francisco JS, Peyerimhoff SD.
PMID: 19256608
J Chem Phys. 2009 Feb 28;130(8):084304. doi: 10.1063/1.3080808.

Quantum chemical calculations are reported for the energies of the few lowest electronic singlet states of oxywater along dissociation of the oxygen-oxygen bond into water and singlet oxygen using multistate multireference second-order Moller-Plesset perturbation theory. We compute an energy...

Intramolecular proton transfer (IPT) in alkoxyamine: a theoretical investigation.

Physical chemistry chemical physics : PCCP

Parkhomenko D, Bagryanskaya EG, Marque SR, Siri D.
PMID: 23838791
Phys Chem Chem Phys. 2013 Sep 07;15(33):13862-71. doi: 10.1039/c3cp50821h. Epub 2013 Jul 10.

The Intramolecular Proton Transfer (IPT) in alkoxyamines is one of the main factors determining the process of Nitroxide Mediated Polymerization (NMP). Recently, we proposed an experimental approach to study IPT and applied it to a series of alkoxyamines. It...

Investigation of extraesophageal gastroesophageal reflux disease.

Annals of gastroenterology

Tsoukali E, Sifrim D.
PMID: 24714277
Ann Gastroenterol. 2013;26(4):290-295.

The most common extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, asthma and laryngitis. There are two mechanisms proposed to explain extraesophageal syndromes caused by GERD. The first one is a direct way via irritation and/or microaspiration...

BACKGROUND: Effective strategies are needed to raise colorectal cancer screening rates among Hispanics.METHODS: We surveyed and randomized 400 Hispanic primary care patients either to a Decision Support and Navigation Intervention (DSNI) Group (RESULTS: Screening adherence was significantly higher in...

Esophageal Baseline Impedance Reflects Mucosal Integrity and Predicts Symptomatic Outcome With Proton Pump Inhibitor Treatment.

Journal of neurogastroenterology and motility

Xie C, Sifrim D, Li Y, Chen M, Xiao Y.
PMID: 29156514
