Yellow catfish (Pelteobagrus fulvidraco) is one of the most important freshwater aquaculture species in China. However, its small size and lower meat yield limit its edible value. Myostatin (MSTN) is a negative regulator of mammalian muscle growth. But, the function of Mstn in fish remains elusive. To explore roles of mstn gene in fish growth and create a strain of yellow catfish with high amou...
As poikilothermic vertebrates, fish can experience changes in water temperature, and hence body temperature, as a result of seasonal changes, migration, or efflux of large quantities of effluent into a body of water. Temperature shifts outside of the optimal temperature range for an individual fish species can have negative impacts on the physiology of the animal, including the immune system. A...
This study examined radiocesium (137Cs) levels in fish from the vicinity of the Department of Energy's Savannah River Site (SRS), a former nuclear weapons production facility in South Carolina. Fish from the Savannah River were sampled above (upstream), along, and below (downstream) the SRS, and from Steel Creek, a tributary that runs through the SRS. There was some off-site contamination of 13...
Sustainable energy derived from waste resources helps to mitigate the greenhouse gas emissions generated fossil fuels. In this study, a solid heterogeneous catalyst was synthesized by using eggshell and copper oxide [CaCu(OCH3)2]. Using catalyst, biodiesel fuels were produced sardine fish oil either methanol, ethanol, or iso-propanol. To reduce acid value of oil, esterification performed before...
Dominance hierarchies are ubiquitous in social species that require social cognition to maintain. Status may be established initially through physical conflict but is maintained by social signals between individuals that depend critically on the relative social status of those interacting. How do individuals collect information they need to modulate their behavior? Using a particularly suitable...
We describe here a simple and versatile method of fluorescence in situ hybridization (FISH) on paraffin-embedded tissue sections with specific application in the study of microchimerism, that is, the presence of intact foreign cells within an individual. This is accomplished through the use of X and Y chromosome-specific probes to identify the presence of male nuclei within a tissue section fro...
UNLABELLED PROBER is an oligonucleotide primer design software application that designs multiple primer pairs for generating PCR probes useful for fluorescence in situ hybridization (FISH). PROBER generates Tiling Oligonucleotide Probes (TOPs) by masking repetitive genomic sequences and delineating essentially unique regions that can be amplified to yield small (100-2000 bp) DNA probes that in ...
