Abstract
We exposed bluegills Lepomis macrochirus to VHSV-IVb by intraperitoneal injection at six temperatures from 10 degrees C to 30 degrees C and followed the disease course by quantitative real-time reverse transcriptase polymerase chain reaction (qrt-RT-PCR). Mortality of injected fish was 90% at 10 deg...

Abstract
We have identified one sox11 homologue, sox11b, from the ovary of the orange-spotted grouper. In the present study, another sox11 homologue, sox11a, was cloned from the brain. The orange-spotted grouper Sox11a contained the signature features of mammalian SOX11 homologues except the Pro-Glu rich reg...

Abstract
The blood of the sub-Antarctic fish Eleginops maclovinus (Em) contains three haemoglobins. The major haemoglobin (Hb1Em) displays the Root effect, a drastic decrease in the oxygen affinity and a loss of cooperativity at acidic pH. The carbomonoxy form of HbEm1 has been crystallized i...
