Sciurid phylogeny and the paraphyly of Holarctic ground squirrels (Spermophilus).
The squirrel family, Sciuridae, is one of the largest and most widely dispersed families of mammals. In spite of the wide distribution and conspicuousness of this group, phylogenetic relationships remain poorly understood. We used DNA sequence data from the mitochondrial cytochrome b gene of 114 species in 21 genera to infer phylogenetic relationships among sciurids based on maximum parsimony a...
متن کاملPlasma ghrelin and desacyl ghrelin concentrations in renal failure.
Ghrelin is a novel hormone that possesses growth hormone (GH)-releasing, cardiovascular, and metabolic activities. Ghrelin is a unique acylated polypeptide, and the naked peptide, desacyl ghrelin, does not have the activity. This study examines plasma ghrelin concentrations in 41 patients with mild to severe renal diseases. Two kinds of radioimmunoassays were used: amino-terminal immunoreactivi...
متن کاملBile constituents in hibernating golden-mantled ground squirrels (Spermophilus lateralis)
BACKGROUND Golden-mantled ground squirrels (S. lateralis) are anorexic during the winter and survive by exploiting hibernation to reduce energetic demands. The liver normally plays a critical role in fueling and regulating metabolism and one might expect significant changes in hepatobiliary function with hibernation. We analyzed bile collected from animals in summer, animals in winter that were...
متن کاملSmoking acutely increases plasma ghrelin concentrations.
To the Editor: Smoking and smoking cessation are associated with weight changes (1), and many smokers give weight gain as a primary reason for not trying to quit smoking (2). A relationship has been reported between smoking and plasma concentrations of ghrelin, a 28-amino acid growth hormone– releasing peptide secreted mainly by the stomach (3–5). Our primary aim was to determine whether smokin...
متن کاملTranscriptome Analysis of Spermophilus lateralis and Spermophilus tridecemlineatus Liver Does Not Suggest the Presence of Spermophilus-Liver-Specific Reference Genes
The expressions of reference genes used in gene expression studies are assumed to be stable under most circumstances. However, studies had demonstrated that genes assumed to be stably expressed in a species are not necessarily stably expressed in other organisms. This study aims to evaluate the likelihood of genus-specific reference genes for liver using comparable microarray datasets from Sper...
