Application of premetamorphic oral cavity electron micrographs for Egyptian toads’ taxonomy

January 2011

In the present study, the microanatomy of both the oral disc and buccal cavity of the tadpole of Bufo regularis was described. Tadpoles of 32, 38 and 40 stages were dissected and analyzed using scanning electron microscope. In all the stages, the mouth was ventral and the oral disk width was large, that is, equal to about 44% of the greatest width of the body. The disk was provided with a broad gap...

Isolation and characterization of breast cancer stem cells from malignant tumours in Vietnamese women

December 2010

Cancer stem cells are the origin of tumors and have been isolated successfully from different kinds of tumors. Breast cancer stem cells have been recently identified in breast carcinoma with markers CD44+/CD24-/dim. This population can cause tumor and display stem cell-like properties. However, direct evidences that breast cancer stem cells can be propagated in vitro is still lacking. This research was carried...

Toxicity evaluation of dextran-spermine polycation as a tool for genetherapy in vitro

December 2010

Cationic polymers are a leading class of nonviral self-assembled nucleic acid delivery systems. Cationic polymers have been shown to condence the DNA so that the entrapped DNA is protected from contact with DNase. The objective of the present study is to evaluate the effect of cationic dextran on the proliferation rate, morphological changes and biosynthetic activities in vitro. Cationic dextran was prepared by...

Morphine is an exogenous ligand for MrgX2, a G protein-coupled receptor for cortistatin

December 2009

MrgX2 is reported to be expressed in a specific subset of dorsal root ganglion sensory neurons and it is activated by the endogenous peptides, cortistatin and proadrenomedullin N-terminal peptide. Here, we show that morphine but not opioid peptides stimulated a dose-dependent increase of the intracellular calcium ion level in MrgX2-expressing cells. Naloxone, an opioid receptor antagonist, did not influence these...
