Impact of treatment planning target volumen (PTV) size on radiation induced diarrhoea following selenium supplementation in gynecologic radiation oncology - a subgroup analysis of a multicenter, phase III trial [PDF]

open access: yes, 2013
Background: In a previous analysis (Int J Radiat Oncol Biol Phys 70:828-835,2010), we assessed whether an adjuvant supplementation with selenium (Se) improves Se status and reduces the radiation-induced side-effects of patients treated by adjuvant ...

Systemic adipokines, hepatokines and interleukin-6 in HCV-monoinfected and HCV/HIV coinfected patients treated with direct antiviral agents (DAAs) [PDF]

open access: yes, 2018
In this study, we demonstrated that that altered levels ofadipokines/hepatokines in HCV-infected patients, including HIV coinfected, can be restored by treatment with direct antiviral agents (DAAs), thus indicating the important metabolic changes ...

Inhibition of selenoprotein synthesis by Zika virus may contribute to congenital Zika syndrome and microcephaly by mimicking SELENOP knockout and the genetic disease PCCA

open access: yesBBA Advances, 2021
Selenium status plays a major role in health impacts of various RNA viruses. We previously reported potential antisense interactions between viral mRNAs and host mRNAs encoding isoforms of the antioxidant selenoprotein thioredoxin reductase (TXNRD). Here,
