Peptide YY is a 36-residue gastrointestinal hormone which inhibits both pancreatic and gastric secretion. We have isolated a cDNA encoding the peptide YY precursor by screening a rat intestinal lambda gt11 cDNA library with an antiserum directed against the porcine hormone. The nucleotide sequence of the cDNA encodes a 98-residue protein (molecular weight, 11, 121) which has an amino acid seque...
Rainbow trout homogametic males, (XX or YY sex genotype), can be obtained, respectively, through masculinisation of genetic females or induced androgenesis. Aim of this study was to compare reproductive potential of neo-males (XX) and super-males (YY) with heterogametic males (XY). We measured spermatozoa motility parameters, sperm concentration, osmolality and characterized protein profiles in...
An exotic species is a species that is not native to its current habitat and is known as invasive if it negatively impacts this habitat. There have been a variety of attempts to eradicate invasive species in different areas, but they have not been particularly successful. In an effort to find a better method for eradicating invasive fish species, Gutierrez and Teem proposed a method involving s...
Background & Objectives: Ghrelin and peptide YY are orexigenic and anorexigenic peptides, respectively. They affect feeding behaviours and play a pivotal role in energy balance and glucose homeostasis. Resistance training is a key component of physical activity guidelines for weight control however, there is limited information on the effects of different intensities of circuit training on...
The collisions of photons at a high energy electron-positron collider provide a comprehensive laboratory for testing QCD, electroweak interactions, and extensions of the standard model. It is expected that by using back-scattered laser beams, that the effective luminosity and, energy of photon-photon collisions will be comparable to that of the primary c+e-collisions. In this talk, I will focus...
YY super-males have rarely been detected in nature and only been artificially created in some fish species including tilapia and yellow catfish (Pelteobagrusfulvidraco), which provides a promising model for testis development and spermatogenesis. In our previous study, significant differences in morphology and miRNA expression were detected between XY and YY testis of yellow catfish. Here, sole...

An insatiable appetite is a cardinal feature of Prader-Willi syndrome (PWS) with stomach rupturing as a reported consequence. Peptide YY, secreted by the intestine and released post-prandially, inhibits appetite, while ghrelin, secreted by the stomach during mealtime hunger, stimulates appetite. Both peptide YY and ghrelin act at the brain level, particularly the hypothalamus. Recently, plasma ...
