DAX-1 (dosage-sensitive sex reversal-adrenal hypoplasia congenita-critical region on the X chromosome gene 1; NR0B1) is an orphan nuclear receptor that plays an important role in the development and functioning of the adrenal gland and hypothalamic-pituitary gonadal axis. The DAX-1 protein acts as a transcriptional repressor of genes involved in the(More)
MicroRNAs are an extensive family of approximately 22-nucleotide-long noncoding RNAs expressed in a wide range of eukaryotes, including humans, and they are important in development and disease. We found that microRNA Mir-17-5p has extensive complementarity to the mRNA of AIB1 (named for "amplified in breast cancer 1"). Cell culture experiments showed that(More)
BACKGROUND Although originally isolated from the bone marrow, mesenchymal stem cells (MSCs) have recently been detected in other tissues. However, little is known about MSCs in the brain. OBJECTIVE To determine the extent to which cells with the features of MSCs exist in normal brain tissue and to determine the location of these cells in the brain. (More)
Although studies have suggested that bone marrow human mesenchymal stem cells (BM-hMSC) may be used as delivery vehicles for cancer therapy, it remains unclear whether BM-hMSCs are capable of targeting cancer stem cells, including glioma stem cells (GSC), which are the tumor-initiating cells responsible for treatment failures. Using standard glioma models,(More)

Steady laminar natural convection over a semi-infinite moving vertical plate in the presence of internal heat generation, viscous dissipation and a convective surface boundary condition in a porous medium is examined in this paper. It is assumed that the left surface of the plate is in contact with a hot fluid while the cold fluid on the right surface of(More)
OBJECTIVE Mesenchymal stem cells (MSCs) have been shown to localize to gliomas after intravascular delivery. Because these cells home to areas of tissue injury, the authors hypothesized that the administration of ionizing radiation (IR) to tumor would enhance the tropism of MSCs to gliomas. Additionally, they sought to identify which radiation-induced(More)
BACKGROUND Human mesenchymal stem cells (hMSCs) have been shown to reside as stromal cells in human gliomas as glioma-associated hMSCs (GA-hMSCs), but their biological role remains unclear. Because recent evidence indicates that GA-hMSCs drive tumor cell proliferation and stemness, we hypothesized that a higher percentage of GA-hMSCs in tumors predicts poor(More)
In static cognitive radio network a secondary transmitter communicates directly with a secondary receiver only when the spectrum is not occupied by any primary user. The secondary user has to stop its transmission when no spectrum holes exist. To improve the transmission capacity, in this paper we approach to combine cognitive radio network with cooperative(More)
