Gas phase infrared multiple photon dissociation spectra of positively charged sodium bis(2-ethylhexyl)sulfosuccinate reverse micelle-like aggregates
2011
The capability of infrared multiple photon dissociation (IRMPD) spectroscopy to gain structural information on surfactant-based supramolecular aggregates has been exploited to elucidate intermolecular interactions and local organization of positively charged sodium bis(2-ethylhexyl)sulfosuccinate (AOTNa) aggregates in the gas phase. A detailed analysis of the stretching modes of the AOTNa CO and SO(3)(-) head groups allows one to directly probe their interactions with sodium counterions and to gain insight in their organization within the aggregate. Similarities and differences of the IRMPD spectra as compared to the infrared absorption spectrum of micellized AOTNa in CCl(4) have been analy…
Theoretical calculation of the vibrational spectra of cis-cis-cyclooctadienes in the vapour phase.
2000
The theoretical infrared spectra of 1,3-cis-cis-cyclooctadiene (1,3-COD) and 1,5-cis-cis-cyclooctadiene (1,5-COD), were obtained by ab initio MO calculations at Hartree-Fock level. The results were compared with the available IR experimental spectra of 1,3- and 1,5-COD. The apparent agreement between theoretical and experimental data allows us to exploit two bands, found only in the case of the theoretical spectrum of 1,4-COD, as a tool for identifying 1,4-COD during its synthesis.
Lateral internal sphincterotomy is still crucial to heal hypertonic chronic anal fissure and normalize the internal anal sphincter tone? Is V-en Y pl…
2021
INTRODUCTION: The role of augmented internal anal sphincter (IAS) tone in the genesis of chronic anal fissure (CAF) is still unclear. Lateral internal sphincterotomy (LIS) is the most employed surgical procedure, aiming to reduce the IAS tone leaving a permanent anatomical alteration and it is burdened by high risk post-operative anal incontinence (AI). The aim of this work was to evaluate if the pre-operative manometric alterations of CAFs with hypertonic IAS would normalize after sphincter preserving surgical procedure. METHODS: We enrolled 108 consecutive patients affected by idiopathic and non-recurrent CAF undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement and pha…
Raman spectroscopy of the high- and low-spin states of the spin crossover complex Fe(phen)2(NCS)2: an initial approach to estimation of vibrational c…
2000
Abstract Raman spectra of the spin-crossover complex Fe(phen)2(NCS)2 in the solid state have been recorded at 785 nm as a function of temperature to investigate the contribution of intramolecular vibrations to the entropy change, ΔS, associated with spin crossover. The modes of major interest for estimating the contribution lie in the range 100–500 cm−1, where the largest qualitative changes with temperature in the Raman spectra were observed. Analysis of these data, with the working assumption of an average frequency in this range as representative of the 15 distortion modes of an idealised FeN6 octahedron, leads to the conclusion that the intramolecular vibrations represent a primary cont…
Prenatal exposure to perfluoroalkyl substances, immune-related outcomes, and lung function in children from a Spanish birth cohort study.
2019
Background: Prenatal exposure to perfluoroalkyl substances (PFASs) has been associated with impaired immune and respiratory health during childhood but the evidence is inconsistent and limited for lung function. We studied the association between prenatal PFASs exposure and immune and respiratory health, including lung function, up to age 7 years in the Spanish INMA birth cohort study. Methods: We assessed four PFASs in maternal plasma samples collected during the 1st trimester of pregnancy (years: 2003-2008): perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorononanoate (PFNA). Mothers reported the occurrence (yes/no) of lower respir…
Prenatal exposure to perfluoroalkyl substances and immune and respiratory outcomes
2018
Prenatal exposure to perfluoroalkyl substances (PFAS) may be associated with impaired immune and respiratory health during childhood but the evidence is scarce and inconsistent. We studied the association between prenatal PFAS exposure and immune and respiratory health up to age 7 years in the Spanish INMA birth cohort (n=1188). We assessed perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorononanoate (PFNA) in maternal plasma samples. Mothers reported the occurrence (yes/no) of chest infections, lower respiratory tract infections, wheezing, asthma, and eczema in the previous 12 months at 1.5 and 4 years of the child and at 7 years.
