Through a high-resolution spectroscopic survey, we analyze the velocity field of 16 planetary nebulae with [WC]or wels-type nuclei in comparison with 8 nebulae having other central star types. We found spectral evidence for finite turbulent velocities in [WC]-type planetary nebulae superimposed on an essentially constant expansion velocity pattern. The nebulae around O-type stars show no eviden...

Pigmentation disorders such as albinism are occasionally associated with hearing impairments in mammals. Therefore, we wanted to investigate whether such a phenomenon also exists in non-mammalian vertebrates. We measured the hearing abilities of normally pigmented and albinotic specimens of two catfish species, the European wels Silurus glanis (Siluridae) and the South American bronze catfish C...

Viral diseases are an increasing threat to the thriving aquaculture industry worldwide. An emerging group of fish pathogens is formed by several ranaviruses, which have been isolated at different locations from freshwater and seawater fish species since 1985. We report the complete genome sequence of European sheatfish ranavirus (ESV), the first ranavirus isolated in Europe, which causes high m...

Bu çalışmada, Atatürk Baraj Gölü'nden toplanan (Mayıs-Mart ayları arasında) Silurus triostegus'un (Heckel, 1843) gonat dokusu yağ içeriği ve asidi (FA) kompozisyonunun belirlenmesi amaçlamıştır. Gonat toplam lipid miktarı, dişi erkek balıklarda sırasıyla Mayıs Eylül aylarında maksimuma ulaşmıştır. Tüm mevsimlerde en fazla bulunan asitleri; doymuş asitleri (SFA) içinde palmitik asit, tekli doyma...

Abstract A novel papillomavirus (PV) was detected in farmed wels catfish ( Silurus glanis ) Hungary showing clinical signs resembling those of herpesvirus disease. The whole genome 1 (SgPV1) identified using next-generation sequencing. 5,612-bp complete contains four predicted protein coding regions (E1, E2, L1, and L2), which seem to have homologues every PV sequenced date. Five fish sequences...
