BACKGROUND Liver grafts from donation after circulatory death (DCD) donors are increasingly accepted as an extension of the organ pool for transplantation. There is little data on the outcome of liver transplantation with DCD grafts from a pediatric donor. The objective of this study was to assess the outcome of liver transplantation with pediatric DCD grafts and to compare this with the outcom...
Oxidative stress induced by ischemia and hypoxia in the livers of donors after brain death (DBD) is associated with poor organ function and low patient survival rates in those receiving DBD liver transplants. Peroxiredoxin 6 (Prdx6) can defend cells against liver damage induced by oxidative stress. The present study aimed to investigate the role of Prdx6 in ischemia‑ and hypoxia‑induced liver d...
The orphan receptors Rev-erbalpha and Rev-erbbeta are members of the nuclear receptors superfamily and act as transcriptional repressors. Rev-erbalpha is expressed with a robust circadian rhythm and is involved in liver metabolism through repression of the ApoA1 gene, but no role has been yet defined for Rev-erbbeta. To gain better understanding of their function and mode of action, we characte...
Retinoid X receptors (RXRs) act as homodimers or heterodimerisation partners of class II nuclear receptors. RXR homo- and heterodimers bind direct repeats of the half-site (A/G)G(G/T)TCA separated by 1 nucleotide (DR1). We present a structural characterization of RXR-DNA binding domain (DBD) homodimers on several natural DR1s and an idealized symmetric DR1. Homodimers displayed asymmetric bindi...
Abstract—Dielectric barrier discharge plasma actuators (DBD-PAs) have been developed for active flow control devices. However, it is necessary to reduce ozone produced by DBD toward practical applications using DBD-PAs. In this study, variations of ozone concentration, flow velocity, power consumption were investigated by changing exposed electrodes of DBD-PAs. Two exposed electrode prototypes ...
امروزه استفاده از محرکهای پلاسمایی جریان متناوب نسبت به جریان مستقیم، جهت کنترل فعال جریان، متداولتر بوده و تقریبأ هیچ کار تحقیقی بر روی پلاسمای جریان مستقیم انجام نگرفته است. در این مقاله با استفاده از یک منبع تغذیه جریان مستقیم و هندسه های گوناگون، خصوصیات پلاسما در هر دو حالت corona و DBD (dielectric barrier discharge) مورد مطالعه قرار گرفت. با استفاده از نتایج این پژوهش مشخص شد که جریان ...
Here we show a novel pathway of transcriptional regulation of a DNA-binding transcription factor by coupled interaction and modification (e.g., acetylation) through the DNA-binding domain (DBD). The oncogenic regulator SET was isolated by affinity purification of factors interacting with the DBD of the cardiovascular transcription factor KLF5. SET negatively regulated KLF5 DNA binding, transact...
This study evaluates the associations among the symptoms of anxiety, depression, and disruptive behavioral disorders (DBD) in the context of their relationships with reactive-proactive aggression and anxiety sensitivity in children with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 342 treatment-naive children with ADHD. The severity of ADHD and DBD symptoms were asse...
NOx (Nitrogen Oxides) and PM (Particular Matter) emitted from diesel engines are one of the causes of air pollution. In this research, NOx removal performance from simulated diesel exhaust gas by Townsend type DBD (Dielectric Barrier Discharge) and filamentary type DBD was investigated. As the results, it became apparent that (1) NO concentration decreased with the increase of specific input en...
Even after the discovery of neutrino flavour oscillations, based on data from atmospheric, solar, reactor, and accelerator experiments, many characteristics of the neutrino remain unknown. Only the neutrino square-mass differences and the mixing angle values have been estimated, while the value of each mass eigenstate still hasn’t. Its nature (massive Majorana or Dirac particle) is still escapi...
