The use of vibrational spectromicroscopy represents a promising approach for monitoring DNA integrity in sperm, although some limitations exist, depending from the experimental conditions. Here, we report that when using FTIR spectromicroscopy to reveal oxidative stress mediated by Fenton's reaction on hydrated sperm samples, DNA damage interpretation is partially compromised by unexpected cell surface precipitates. The precipitates give a broad band in the 1150-1000cm(-1) infrared region, which partially covers one of the signatures of DNA (phosphate stretching bands), and are detected as iron and oxygen containing material when using XRF spectroscopy. On the other hand, the analyses further support the potential of FTIR spectromicroscopy to reveal cellular oxidative damage events such as lipid peroxidation, protein misfolding and aggregations, as well as DNA strain breaks.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/26923261?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%">Pascolo, Lorella</style></author><author><style face="normal" font="default" size="100%">Borelli, Violetta</style></author><author><style face="normal" font="default" size="100%">Canzonieri, Vincenzo</style></author><author><style face="normal" font="default" size="100%">Gianoncelli, Alessandra</style></author><author><style face="normal" font="default" size="100%">Birarda, Giovanni</style></author><author><style face="normal" font="default" size="100%">Bedolla, Diana E</style></author><author><style face="normal" font="default" size="100%">Salomè, Murielle</style></author><author><style face="normal" font="default" size="100%">Vaccari, Lisa</style></author><author><style face="normal" font="default" size="100%">Calligaro, Carla</style></author><author><style face="normal" font="default" size="100%">Cotte, Marine</style></author><author><style face="normal" font="default" size="100%">Hesse, Bernhard</style></author><author><style face="normal" font="default" size="100%">Luisi, Fernando</style></author><author><style face="normal" font="default" size="100%">Zabucchi, Giuliano</style></author><author><style face="normal" font="default" size="100%">Melato, Mauro</style></author><author><style face="normal" font="default" size="100%">Rizzardi, Clara</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Differential protein folding and chemical changes in lung tissues exposed to asbestos or particulates.</style></title><secondary-title><style face="normal" font="default" size="100%">Sci Rep</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Sci Rep</style></alt-title></titles><dates><year><style  face="normal" font="default" size="100%">2015</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2015</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">5</style></volume><pages><style face="normal" font="default" size="100%">12129</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Environmental and occupational inhalants may induce a large number of pulmonary diseases, with asbestos exposure being the most risky. The mechanisms are clearly related to chemical composition and physical and surface properties of materials. A combination of X-ray fluorescence (μXRF) and Fourier Transform InfraRed (μFTIR) microscopy was used to chemically characterize and compare asbestos bodies versus environmental particulates (anthracosis) in lung tissues from asbestos exposed and control patients. μXRF analyses revealed heterogeneously aggregated particles in the anthracotic structures, containing mainly Si, K, Al and Fe. Both asbestos and particulates alter lung iron homeostasis, with a more marked effect in asbestos exposure. μFTIR analyses revealed abundant proteins on asbestos bodies but not on anthracotic particles. Most importantly, the analyses demonstrated that the asbestos coating proteins contain high levels of β-sheet structures. The occurrence of conformational changes in the proteic component of the asbestos coating provides new insights into long-term asbestos effects.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/26159651?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%">Delfino, Riccarda</style></author><author><style face="normal" font="default" size="100%">Altissimo, Matteo</style></author><author><style face="normal" font="default" size="100%">Menk, Ralf Hendrik</style></author><author><style face="normal" font="default" size="100%">Alberti, Roberto</style></author><author><style face="normal" font="default" size="100%">Klatka, Tomasz</style></author><author><style face="normal" font="default" size="100%">Frizzi, Tommaso</style></author><author><style face="normal" font="default" size="100%">Longoni, Antonio</style></author><author><style face="normal" font="default" size="100%">Salomè, Murielle</style></author><author><style face="normal" font="default" size="100%">Tromba, Giuliana</style></author><author><style face="normal" font="default" size="100%">Arfelli, Fulvia</style></author><author><style face="normal" font="default" size="100%">Clai, Milan</style></author><author><style face="normal" font="default" size="100%">Vaccari, Lisa</style></author><author><style face="normal" font="default" size="100%">Lorusso, Vito</style></author><author><style face="normal" font="default" size="100%">Tiribelli, Claudio</style></author><author><style face="normal" font="default" size="100%">Pascolo, Lorella</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">X-ray fluorescence elemental mapping and microscopy to follow hepatic disposition of a Gd-based magnetic resonance imaging contrast agent.</style></title><secondary-title><style face="normal" font="default" size="100%">Clin Exp Pharmacol Physiol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Clin.

Spatially resolved X-ray fluorescence (XRF) spectroscopy with synchrotron radiation is a technique that allows imaging and quantification of chemical elements in biological specimens with high sensitivity. In the present study, we applied XRF techniques at a macro and micro level to carry out drug distribution studies on ex vivo models to confirm the hepatobiliary disposition of the Gd-based magnetic resonance imaging contrast agent B22956/1. 2. Gd presence was selectively quantified allowing the determination of the time dependent disappearance of the drug from blood and its hepatic accumulation in mice after administration. Elemental mapping highlighted the drug distribution differences between healthy and diseased livers. XRF microanalyses showed that in CCl(4) -induced hepatitis, B22956/1 has greatly reduced hepatic accumulation, shown as a 20-fold reduction of Gd presence. Furthermore, a significant increase of Fe presence was found in steatotic compared with healthy livers, in line with the disease features. 3. The present results show that XRF might be useful in preclinical pharmacological studies with drugs containing exogenous elements. Furthermore, quantitative and high-sensitivity elemental mapping allows simultaneous detection of chemical variation, showing pathological conditions. This approach was useful in suggesting reduced B22956/1 accumulation in steatotic livers, thus opening possible new diagnostic perspectives for this drug.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21957877?dopt=Abstract</style></custom1></record></records></xml>
