Biology (Basel). 2018 Jan 11;7(1): Authors: Siniscalco D, Trotta MC, Brigida AL, Maisto R, Luongo M, Ferraraccio F, D'Amico M, Di Filippo C Abstract Background: The rat model of streptozotocin (STZ)-induced pancreatic damage was used to examine whether a systemic oxygen/ozone mixture could be beneficial for the pancreas by reducing the machinery of the local detrimental mediators released by STZ. Results: The results showed that oxygen/ozone administration (150 µg/Kg i.p.) for ten days in STZ rats increased the endogenous glutathione-s-transferase (GST) enzyme and nuclear factor-erythroid 2-related factor 2 (Nrf2) into the pancreatic tissue, together with reduction of 4-hydroxynonenal (4-HNE) and PARP-1 compared to STZ rats receiving O₂ only. Interestingly, these changes resulted in higher levels of serum insulin and leptin, and pancreatic glucagon immunostaining. Consequently, glucose metabolism improved as evidenced by the monitoring of glycemia throughout. Conclusions: This study provides evidence that systemic administration of oxygen/ozone reduces the machinery of detrimental mediators released by STZ into the pancreas with less local damage and better functionality.

Adv Gerontol. 2017;30(5):698-702 Authors: Fridman NV, Linkova NS, Polyakova VO, Drobintseva AO, Тrofimova SV, Kvetnoy IM, Khavinson VK Abstract Skin aging is one of the topical issues in modern gerontocosmetology. Application of cosmetic products with short peptides is a promising measure for retardation of skin aging. This research is aimed at investigation of KE (Lys-Glu, Vilon) dipeptide influence on the expression of markers of aging in human skin fibroblasts in vitro. Collagen type I and sirtuin-6 expression in «young» and «old» skin cell fibroblasts cultures was studied using immunofluorescence confocal microscopy method. The areas of expression of collagen type I and sirtuin-6 are known to decrease in skin fibroblasts with aging by 3,5 and 3,6 times accordingly. KE dipeptide increases collagen type I expression area in «old» skin fibroblasts cultures by 83%. KE dipeptide increases expression area of sirtuin-6 in «young» and «old» skin fibroblasts cultures by 1,6 and 2,6 times correspondingly. Thus, KE dipeptide promotes functional activity of skin fibroblasts and inhibits their aging. PMID: 29322736 [PubMed - in process]

Volatilization and oxidative artifacts of PM bound PAHs at low volume sampling (2): Evaluation and comparison of mitigation strategies effects.

Chemosphere. 2017 Dec;189:330-339 Authors: Balducci C, Cecinato A, Paolini V, Guerriero E, Perilli M, Romagnoli P, Tortorella C, Nacci RM, Giove A, Febo A Abstract The artifacts induced by oxidative degradation and volatilization were assessed with regards to determination of particulate atmospheric PAHs collected at low volume conditions (2.3 m3 h-1) according to the EU Reference Method EN 12341:2014. In order to evaluate the oxidative degradation, PAH measures carried out through collecting airborne particulate with and without ozone denuders were examined. Simultaneously, the influence of volatilization was investigated by comparing concentrations of PAHs in particulate samples collected over 24-h and 12-h using conventional instruments. Summer and winter/spring campaigns were carried out in order to assess the influence of environmental contour on the artifact processes. Oxidative degradation led to a general decrease of PAH concentrations in both periods; in particular, the highest losses were observed for benzo[a]pyrene and perylene reaching, in average, ca. 20%. In the summer, the effect of volatilization exceeded that of oxidative degradation for light PAHs up to benzo[e]pyrene. In the winter/spring time, the influence of both artifact typologies could be mitigated by splitting the normal 24-h collection interval starting at midnight into two 12-h intervals. A mitigation of the losses could even be obtained by fixing the start time sampling fixed at noon or in the first hours of the day. Finally, the feasibility of collecting PAHs through prolonged sampling (>1 month) at the flow rate of 1.1 L min-1 was preliminarily investigated. Results indicated that this approach is unsuitable for minimizing the oxidative artifacts. PMID: 28942259 [PubMed - indexed for MEDLINE]
