Introduction: Bleomycins are DNA-binding biomolecules, which can be used as targeted therapy carriers when labeled with particle-emitters such as Yb-175. In this work the development of Yb-175 bleomycin (Yb-BLM) has been reported. Methods: Yb-175 chloride was obtained by thermal neutron irradiation (3 × 10 n.cm.s) of natural Yb2O3 samples at various neutron fluxes and irradiation times. The rad...

OBJECTIVE Optimized production and quality control of ytterbium-175 (Yb-175) labeled pamidronate and alendronate complexes as efficient agents for bone pain palliation has been presented. METHODS Yb-175 labeled pamidronate and alendronate (175Yb-PMD and 175Yb-ALN) complexes were prepared successfully at optimized conditions with acceptable radiochemical purity, stability and significant hydro...

Introduction: Nano radio-pharmaceutical therapy (NRPT) is a new method for solid tumor therapy. The treatment uses a radioactive form of radionuclide encapsulated in the poly amido amine dendrimers. The poly (amidoamine) (PAMAM) dendrimers have attracted attentions for cancer treatment by their characteristics of targeted drug carriers, delivery agents, and imaging agents in hu...

Selection of operating wavelength of the Yb-doped fiber-ring lasers using longperiod fiber gratings (LPFGs) is suggested. In the proposed method, customized LPFG that sustains high powers serves as a broad-band rejection filter. It modifies the net gain profile of the laser, enabling the peak gain to occur at a designed wavelength. Spectral range of oscillation between 1050-1110 nm was experime...

YB-1 is a member of the numerous families of proteins with an evolutionary ancient cold-shock domain. It is involved in many DNA- and RNA-dependent events and regulates gene expression at different levels. Previously, we found a regulatory element within the 3' untranslated region (UTR) of YB-1 mRNA that specifically interacted with YB-1 and poly(A)-binding protein (PABP); we also showed that P...

PURPOSE Y-box-binding protein-1 (YB-1) is known to conduct various functions related to cell proliferation, anti-apoptosis, epithelial-mesenchymal transition, and castration resistance in prostate cancer. However, it is still unknown how YB-1 affects cancer biology, especially its correlations with the mitogen-activated protein kinase (MAPK) signaling pathway. Therefore, we aimed to examine the...

Y-box binding protein-1 (YB-1) is an oncogenic transcription/translation factor expressed in >40% of breast cancers, where it is associated with poor prognosis, disease recurrence, and drug resistance. We questioned whether this may be linked to the ability of YB-1 to induce the expression of genes linked to cancer stem cells such as CD44 and CD49f. Herein, we report that YB-1 binds the CD44 an...
