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.

Since innate immunity may be hypothesized as involved in the susceptibility to OLP, we studied human beta defensin 1 (hBD-1) an antimicrobial peptide constitutively expressed in the saliva, looking at functional genetic variants possibly able to diminish hBD-1 production an consequently conferring major susceptibility to OLP.&lt;/p&gt;&lt;p&gt;&lt;b&gt;DESIGN: &lt;/b&gt;We analysed three DEFB1 polymorphisms at 5' UTR, -52G&gt;A (rs1799946), -44C&gt;G (rs1800972), -20G&gt;A (rs11362) and two DEFB1 polymorphisms at 3'UTR, c*5G&gt;A (rs1047031), c*87A&gt;G (rs1800971), with the aim of correlating these genetic variants and hBD-1 salivary level in a group of OLP patients and in healthy subjects. We also evaluated hBD-1 salivary concentrations, using ELISA, in OLP and healthy controls.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;We compared hBD-1 concentrations in OLP and healthy subjects: hBD-1 concentration was significantly higher in OLP patients respect to control. When considering the correlation between DEFB1 polymorphisms genotypes and hBD-1 expression levels, significant results were obtained for SNPs -52G&gt;A (p=0.03 both in OLP patients and healthy individuals) and -44C&gt;G (p=0.02 in OLP patients).&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;hBD-1 production was different between OLP and healthy subjects (not age-matched with OLP). DEFB1 gene polymorphisms, -52G&gt;A and -44C&gt;G, correlated with hBD-1 salivary concentrations.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27770642?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%">Ottaviani, Giulia</style></author><author><style face="normal" font="default" size="100%">Gobbo, Margherita</style></author><author><style face="normal" font="default" size="100%">Cecco, Luca</style></author><author><style face="normal" font="default" size="100%">Alberi, Giulia</style></author><author><style face="normal" font="default" size="100%">Pozzato, Gabriele</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%">Impact of DEFB1 gene regulatory polymorphisms on hBD-1 salivary concentration.</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.

Individual genetic variations within the DEFB1 gene, encoding for hBD-1, could influence gene expression and protein production.&lt;/p&gt;&lt;p&gt;&lt;b&gt;DESIGN: &lt;/b&gt;Three DEFB1 polymorphisms at 5' untranslated region (UTR), -52G &gt; A (rs1799946), -44C &gt; G (rs1800972) and -20G &gt; A (rs11362), and two polymorphisms at DEFB1 3' UTR, c*5G &gt; A (rs1047031) and c*87A &gt; G (rs1800971), were analysed by direct sequencing and correlated with hDB-1 salivary concentration (tested with enzyme-linked immunosorbent assay (ELISA)) in 40 healthy subjects.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;Significant associations were found between individuals presenting different DEFB1 polymorphisms at positions -52 and -44 of the gene and hBD-1 salivary concentrations: -52 G/G carriers had higher levels of protein than G/A and A/A; -44C/G subjects showed a higher protein concentration than homozygous wild-type C/C.

In addition, the association between sweet liking and sugar intake with dental caries was investigated. Caries was measured by the decayed, missing, filled teeth (DMFT) index in 647 Caucasian subjects (285 males and 362 females, aged 18-65 years), coming from six villages in northeastern Italy. Sweet liking was assessed using a 9-point scale, and the mean of the liking given by each individual to specific sweet food and beverages was used to create a sweet liking score. Simple sugar consumption was estimated by a dietary history interview, considering both added sugars and sugar present naturally in foods. Our study confirmed that polymorphisms in TAS1R2 and GLUT2 genes are related to DMFT index. In particular, GG homozygous individuals for rs3935570 in TAS1R2 gene (p value = 0.0117) and GG homozygous individuals for rs1499821 in GLUT2 gene (p value = 0.0273) showed higher DMFT levels compared to both heterozygous and homozygous for the alternative allele. Furthermore, while the relationship sugar intake-DMFT did not achieve statistical significance (p value = 0.075), a significant association was identified between sweet liking and DMFT (p value = 0.004), independent of other variables. Our study showed that sweet taste genetic factors contribute to caries prevalence and highlighted the role of sweet liking as a predictor of caries risk. Therefore, these results may open new perspectives for individual risk identification and implementation of target preventive strategies, such as identifying high-risk patients before caries development.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/26268603?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%">Chermetz, Maddalena</style></author><author><style face="normal" font="default" size="100%">Gobbo, Margherita</style></author><author><style face="normal" font="default" size="100%">Ronfani, Luca</style></author><author><style face="normal" font="default" size="100%">Ottaviani, Giulia</style></author><author><style face="normal" font="default" size="100%">Zanazzo, Giulio A</style></author><author><style face="normal" font="default" size="100%">Verzegnassi, Federico</style></author><author><style face="normal" font="default" size="100%">Treister, Nathaniel S</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%">Class IV laser therapy as treatment for chemotherapy-induced oral mucositis in onco-haematological paediatric patients: a prospective study.</style></title><secondary-title><style face="normal" font="default" size="100%">Int J Paediatr Dent</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Int J Paediatr Dent</style></alt-title></titles><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2014 Nov</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">24</style></volume><pages><style face="normal" font="default" size="100%">441-9</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;BACKGROUND: &lt;/b&gt;Oral mucositis is a debilitating side effect of chemotherapy.

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. Laser therapy was well tolerated with remarkable reduction in pain associated with oral mucositis after 1-2 days of laser therapy.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;Given class IV laser therapy appears to be safe, non-invasive, and potentially effective, prospective, randomized, controlled trials are necessary to further assess efficacy and to determine optimal treatment parameters.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24372909?dopt=Abstract</style></custom1></record></records></xml>
