Analysis of photoreactivity and phototoxicity of riboflavin's analogue 3MeTARF
The objective of undertaken study was to elucidate mechanisms of 3MeTARF photoreactivity under the irradiation with blue light in comparison to its mater compound, riboflavin. We approached this goal by using spectroscopic methods, like direct singlet oxygen phosphorescence detection at 1270 nm, EPR spin trapping and oximetry. Additionally, we tested both riboflavin and 3MeTARF phototoxicity against melanoma cells (WM115) and we studied mechanism of photodynamic cell death, as well. Moreover, 3MeTARF induces apoptosis in melanoma cells at ten times lower concentration than riboflavin itself. Our studies confirmed that 3M...

Publication date: Available online 15 January 2020Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Rui Si, Chao Gao, Rui Guo, Chen Lin, Jiayi Li, Wenyi GuoAbstractAcute Myocardial Infarction (MI) is one of the foremost causes of human death worldwide and it leads to mass death of cardiomyocytes, interchanges of unfavorable biological environment and affecting electrical communications by fibrosis scar formations, and specifically deficiency of blood supply to heart which leads to heart damage and heart failure. Recently, numerous appropriate strategies have been applied to base on solve these problem...

The detection sensitivity of commonly used singlet oxygen probes in aqueous environments
Publication date: Available online 11 January 2020Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Tiago Entradas, Sarah Waldron, Martin VolkAbstractThe sensitivity for singlet oxygen (1O2) of two convenient 1O2 probes, 1,3-diphenylisobenzofuran (DPBF) and 9,10-Anthracenediyl-bis(methylene)dimalonic acid (ABDA), has been investigated in different aqueous environments. Both probes are commercially available at reasonable cost and can be used with standard UV–vis spectrometers. Although DPBF is not soluble in neat water and is not specific to the detection of 1O2, it has very high, essentially di...

Recovery of inferior alveolar nerve by photobiomodulation therapy using two laser wavelengths: A behavioral and immunological study in rat
Publication date: Available online 10 January 2020Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Neda Hakimiha, Mohammad Mehdi Dehghan, Homa Manaheji, Jalal Zaringhalam, Saeed Farzad Mohajeri, Reza Fekrazad, Neda MoslemiAbstractPostoperative sensory disturbances of inferior alveolar nerve (IAN) are major challenges in dental procedures. We aimed to investigate the effect of photobiomodulation therapy (PBMT) with 810 nm and 980 nm diode lasers on behavioral and immunological factors in a rat IAN crush model. Seventy-two rats were randomly assigned to the four groups of 810 nm laser (crush inju...
