Detection and analysis of new psittacine beak and feather disease virus (PBFDv) nucleotide sequences

ΔΕΝ ΥΠΑΡΧΕΙ ΠΕΡΙΛΗΨΗPsittacine beak and feather disease (PBFD) affects a large number of Psittaciformes species. In this study, five White Cockatoo parrots (Cacatua alba) with clinical signs of PBFD were examined. After euthanasia, a full necropsy of parrots was performed and organs with macroscopic changes were sampled for routine histopathological evaluation. To confirm the presence of psittacine beak and feather disease virus (PBFDv), feather samples were analyzed with the PCR method. Sequence analysis of the obtained PCR products indicated their close relationship (99%) to other PBFDv isolates. Six variable nucleotide sites were discovered, two missense and four silent mutations. This paper presents the evidence of new PBFDv sequence in Cockatoo species

Effects of altered hepatic lipid metabolism on regulation of hepatic iNOS

An altered hepatic lipid metabolism involves multifactorial pathologies such as hepatic inflammation, insulin resistance and oxidative stress. Immunity has an essential role in the regulation of glucose and lipid metabolism in the liver. Inducible nitric oxide (NO) synthase (iNOS) has been proposed as an important factor that interplays between immunity and energy metabolism and also in the pathogenesis of obesity-linked insulin resistance. In the liver, locally produced NO plays a protective role during inflammation, and the balance of NO protective and cytotoxic effects is very important. This review is focused on understanding the molecular mechanisms of iNOS regulation in the state of altered hepatic lipid metabolism, which is critical for developing new strategies for treatment of hepatic disorders
