The complete mitogenome the longtail butterfly ray (Gymnura poecilura) was first presented in this study. It is 17,874 bp in length, contains 37 genes with the typical gene order and transcriptional direction in vertebrates. The overall base composition is: 28.5% A, 26.5% T, 15.0% G and 30.1% C. There are 26 bp overlaps and 41 bp short intergenic spaces(More)
Fitting quantitative structure-activity relationships (QSAR) requires different statistical methodologies and, to some degree, philosophies depending on the "shape" of the data matrix. When few features are used and there are many compounds, it is a reasonable expectation that good feature subset selection may be made and that nonlinearities and(More)
The complete mitochondrial genome of the pelagic thresher Alopias pelagicus is first presented in this study. It is 16,692 bp in length and contains the 37 genes and 1 control region with the typical gene order and transcriptional direction in the vertebrates. The overall base composition is 32.1% A, 29.3% T, 25.3% C and 13.3% G. Totally, 27 bp overlaps and(More)
Protein 4.1N belongs to the protein 4.1 superfamily that links transmembrane proteins to the actin cytoskeleton. Recent evidence has shown that protein 4.1 is important in tumor suppression. However, the functions of 4.1N in the metastasis of breast cancer are largely unknown. In the present study, MCF-7, T-47D and MDA-MB-231 breast cancer cell lines with(More)
The complete mitochondrial genome of the brown guitarfish Rhinobatos schlegelii is presented for the first time in this study. It is 16,780 bp in length, consisting 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 putative control region with the typical gene order and direction of transcription in vertebrates. The overall base composition is(More)
The complete mitochondrial genome of the endangered scalloped hammerhead Sphyrna lewini was firstly determined in this study. It is 16,726 bp in length with the typical gene composition and orders in vertebrates. The overall base composition is 31.4% A, 26.3% C, 13.2% G and 29.1% T. Two start codon (ATG and GTG) and three stop codon (TAG, AGA and TAA/TA/T)(More)
In this study, we first presented the complete mitochondrial genome of the blue shark Prionace Glauca, a pelagic and oceanic species. It is 16,705 bp in length and contains 2 rRNA genes, 22 tRNA genes, 13 protein-coding genes and 1 putative control region. The overall base composition is 31.6% A, 24.4% C, 13.1% G and 30.9% T. Overlaps and short inter-genic(More)
The complete mitochondrial genome of Mustelus griseus was first determined in this study. It is 16,754 bp in length, consisting of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region with the typical gene order in vertebrates. Overall nucleotide base composition of the mitogenome is 30.7% A, 24.9% C, 14.0% G and 30.3% T. After(More)
The bull shark Carcharhinus leucas is a large elasmobranch species widespread in tropical and warm oceans, rivers and lakes. We first determine the complete mitogenome of C. leucas in this article. It is 16,704 bp in length, consists 37 genes and one control region with the typical gene order in vertebrates. The ND6 gene used the rare AGG as stop codon. The(More)
OBJECTIVES To identify the pulmonary hypertension (PH) patients who develop an exercise induced venous-to-systemic shunt (EIS) by performing the cardiopulmonary exercise test (CPET), analyse the changes of CPET measurements during exercise and compare the exercise physiology and resting pulmonary hemodynamics between shunt-PH and no-shunt-PH patients.
