It is suggested that the GBCAs prolonged permanence in blood in these patients may result in a Gd precipitation in peripheral or central organs, where it initiates a fibrotic process. In this study we investigated new sites of retention/precipitation of Gd in a mouse model of renal disease (5/6 nephrectomy) receiving two doses (closely after each other) of a linear GBCA. Two commercial GBCAs (Omniscan® and Magnevist®) were administered at doses slightly higher than those used in clinical practice (0.7 mmol/kg body weight, each). The animals were sacrificed one month after the last administration and the explanted organs (kidney, liver, femur, dorsal skin, teeth) were analysed by X-ray fluorescence (XRF) at two synchrotron facilities. The XRF analysis with a millimetre-sized beam at the SYRMEP beamline (Elettra, Italy) produced no detectable levels of Gd in the examined tissues, with the notable exception of the incisors of the nephrectomised mice. The XRF analyses at sub-micron resolution performed at ID21 (ESRF, France) allowed to clearly localize Gd in the periodontal ligaments of teeth both from Omniscan® and Magnevist® treated nephrectomised mice. The latter results were further confirmed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The study prompts that prolonged permanence of GBCAs in blood may result in Gd retention in this particular muscular tissue, opening possibilities for diagnostic applications at this level when investigating Gd-related toxicities.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/30476537?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Gobbo, Margherita</style></author><author><style face="normal" font="default" size="100%">Verzegnassi, Federico</style></author><author><style face="normal" font="default" size="100%">Ronfani, Luca</style></author><author><style face="normal" font="default" size="100%">Zanon, Davide</style></author><author><style face="normal" font="default" size="100%">Melchionda, Fraia</style></author><author><style face="normal" font="default" size="100%">Bagattoni, Simone</style></author><author><style face="normal" font="default" size="100%">Majorana, Alessandra</style></author><author><style face="normal" font="default" size="100%">Bardellini, Elena</style></author><author><style face="normal" font="default" size="100%">Mura, Rosamaria</style></author><author><style face="normal" font="default" size="100%">Piras, Alessandra</style></author><author><style face="normal" font="default" size="100%">Petris, Maria Grazia</style></author><author><style face="normal" font="default" size="100%">Mariuzzi, Maria Livia</style></author><author><style face="normal" font="default" size="100%">Barone, Angelica</style></author><author><style face="normal" font="default" size="100%">Merigo, Elisabetta</style></author><author><style face="normal" font="default" size="100%">Decembrino, Nunzia</style></author><author><style face="normal" font="default" size="100%">Vitale, Marina Consuelo</style></author><author><style face="normal" font="default" size="100%">Berger, Massimo</style></author><author><style face="normal" font="default" size="100%">Defabianis, Patrizia</style></author><author><style face="normal" font="default" size="100%">Biasotto, Matteo</style></author><author><style face="normal" font="default" size="100%">Ottaviani, Giulia</style></author><author><style face="normal" font="default" size="100%">Zanazzo, Giulio Andrea</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Multicenter randomized, double-blind controlled trial to evaluate the efficacy of laser therapy for the treatment of severe oral mucositis induced by chemotherapy in children: laMPO RCT.</style></title><secondary-title><style face="normal" font="default" size="100%">Pediatr Blood Cancer</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Pediatr Blood Cancer</style></alt-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2018 Aug</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">65</style></volume><pages><style face="normal" font="default" size="100%">e27098</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;&lt;b&gt;OBJECTIVES: &lt;/b&gt;To demonstrate the efficacy of laser photobiomodulation (PBM) compared to that of placebo on severe oral mucositis (OM) in pediatric oncology patients. The primary objective was the reduction of OM grade (World Health Organization [WHO] scale) 7 days after starting PBM. Secondary objectives were reduction of pain, analgesic consumption, and incidence of side effects.&lt;/p&gt;&lt;p&gt;&lt;b&gt;METHODS: &lt;/b&gt;One hundred and one children with WHO grade &gt; 2 chemotherapy-induced OM were enrolled in eight Italian hospitals. Patients were randomized to either PBM or sham treatment for four consecutive days (days +1 to +4). On days +4, +7, and +11, OM grade, pain (following a 0-10 numeric pain rating scale, NRS) and need for analgesics were evaluated by an operator blinded to treatment.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;Fifty-one patients were allocated to the PBM group, and 50 were allocated to the sham group. In total, 93.7% of PBM patients and 72% of sham patients had OM grade &lt; 3 WHO on day +7 (P = 0.01). A significant reduction of pain was registered on day +7 in the PBM versus sham group (NRS 1 [0-3] vs. 2.5 [1-5], P &lt; 0.006). Reduced use of analgesics was reported in the PBM group, although it was not statistically significant. No significant adverse events attributable to treatment were recorded.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;PBM is a safe, feasible, and effective treatment for children affected by chemotherapy-induced OM, as it accelerates mucosal recovery and reduces pain.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/29727048?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Rupel, Katia</style></author><author><style face="normal" font="default" size="100%">Zupin, Luisa</style></author><author><style face="normal" font="default" size="100%">Colliva, Andrea</style></author><author><style face="normal" font="default" size="100%">Kamada, Anselmo</style></author><author><style face="normal" font="default" size="100%">Poropat, Augusto</style></author><author><style face="normal" font="default" size="100%">Ottaviani, Giulia</style></author><author><style face="normal" font="default" size="100%">Gobbo, Margherita</style></author><author><style face="normal" font="default" size="100%">Fanfoni, Lidia</style></author><author><style face="normal" font="default" size="100%">Gratton, Rossella</style></author><author><style face="normal" font="default" size="100%">Santoro, Massimo</style></author><author><style face="normal" font="default" size="100%">Di Lenarda, Roberto</style></author><author><style face="normal" font="default" size="100%">Biasotto, Matteo</style></author><author><style face="normal" font="default" size="100%">Zacchigna, Serena</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Photobiomodulation at Multiple Wavelengths Differentially Modulates Oxidative Stress  and .</style></title><secondary-title><style face="normal" font="default" size="100%">Oxid Med Cell Longev</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Oxid Med Cell Longev</style></alt-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Adult</style></keyword><keyword><style  face="normal" font="default" size="100%">Aged</style></keyword><keyword><style  face="normal" font="default" size="100%">Aged, 80 and over</style></keyword><keyword><style  face="normal" font="default" size="100%">Female</style></keyword><keyword><style  face="normal" font="default" size="100%">Humans</style></keyword><keyword><style  face="normal" font="default" size="100%">Keratinocytes</style></keyword><keyword><style  face="normal" font="default" size="100%">Lasers, Semiconductor</style></keyword><keyword><style  face="normal" font="default" size="100%">Low-Level Light Therapy</style></keyword><keyword><style  face="normal" font="default" size="100%">Male</style></keyword><keyword><style  face="normal" font="default" size="100%">Middle Aged</style></keyword><keyword><style  face="normal" font="default" size="100%">Neutrophils</style></keyword><keyword><style  face="normal" font="default" size="100%">Oxidation-Reduction</style></keyword><keyword><style  face="normal" font="default" size="100%">Oxidative Stress</style></keyword><keyword><style  face="normal" font="default" size="100%">Stomatitis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2018</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">2018</style></volume><pages><style face="normal" font="default" size="100%">6510159</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Photobiomodulation (PBM) is emerging as an effective strategy for the management of multiple inflammatory conditions, including oral mucositis (OM) in cancer patients who receive chemotherapy or radiotherapy. Still, the poor understanding of the mechanisms by which the light interacts with biological tissues and the heterogeneity of light sources and protocols employed worldwide significantly limits its applicability. Reactive oxygen species (ROS) are massively generated during the early phases of OM and play a major role in the pathogenesis of inflammation in general. Here, we report the results of a clinical and experimental study, aimed at evaluating the effect of laser light at different wavelengths on oxidative stress  in oncologic patients suffering from OM and  in two cell types abundantly present within the inflamed oral mucosa, neutrophil polymorphonuclear (PMN) granulocytes, and keratinocytes. In addition to standard ROS detection methods, we exploited a roGFP2-Orp1 genetically encoded sensor, allowing specific, quantitative, and dynamic imaging of redox events in living cells in response to oxidative stress and PBM. We found that the various wavelengths differentially modulate ROS production. In particular, the 660 nm laser light increases ROS production when applied either before or after an oxidative stimulus. In contrast, the 970 nm laser light exerted a moderate antioxidant activity both in the saliva of OM patients and in both cell types. The most marked reduction in the levels of ROS was detected in cells exposed either to the 800 nm laser light or to the combination of the three wavelengths. Overall, our study demonstrates that PBM exerts different effects on the redox state of both PMNs and keratinocytes depending on the used wavelength and prompts the validation of a multiwavelength protocol in the clinical settings.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/30534349?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Polesello, Vania</style></author><author><style face="normal" font="default" size="100%">Zupin, Luisa</style></author><author><style face="normal" font="default" size="100%">Di Lenarda, Roberto</style></author><author><style face="normal" font="default" size="100%">Biasotto, Matteo</style></author><author><style face="normal" font="default" size="100%">Pozzato, Gabriele</style></author><author><style face="normal" font="default" size="100%">Ottaviani, Giulia</style></author><author><style face="normal" font="default" size="100%">Gobbo, Margherita</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Segat, Ludovica</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEFB1 polymorphisms and salivary hBD-1 concentration in Oral Lichen Planus patients and healthy subjects.</style></title><secondary-title><style face="normal" font="default" size="100%">Arch Oral Biol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Arch.

Patients were treated with class IV laser therapy for four consecutive days; the assessment of OM was performed through WHO Oral Mucositis Grading Objective Scale, and pain was evaluated through visual analogue scale. Patients completed a validated questionnaire, and photographs of lesions were taken during each session. Patients were re-evaluated 11 days after the first day of laser therapy.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;All patients demonstrated improvement in pain sensation, and all mucositis was fully resolved at the 11-day follow-up visit, with no apparent side effects.
