Using Integrins for Tumor Imaging

Comparative Studies of High Contrast Fluorescence Imaging Efficiency of Silica-coated CdSe Quantum Dots with Green and Red Emission

Herein we report the possibility of using green and red emitting silica-coated cadmium selenide (CdSe) quantum dots (QDs) for remarkable stem and cancer cellular imaging, efficient cellular uptake and fluorescence imaging of semi and ultra-thin sections of tumor for in vivo tumor targeted imaging applications. The comparative studies of high contrast cellular imaging behaviours of the silica-co...

Differentiation of active tumor from edematous regions of glioblastoma multiform tumor in diffusion MR images using heterogeneity analysis method

Background: Due to intrinsic heterogeneity of cellular distribution and density within diffusion weighted images (DWI) of glioblastoma multiform (GBM) tumors, differentiation of active tumor and peri-tumoral edema regions within these tumors is challenging. The aim of this paper was to take advantage of the differences among heterogeneity of active tumor and edematous regions within the gliobla...

Possible role for integrins in the development of tolerance to the analgesic effect of morphine in male rats

There is some evidence supporting the reduced activity of integrins following chronic administration of morphine. This reduction might play a role in morphine tolerance development. Manganese binds to the extracellular domain of integrins and makes them to be activated. The effect of integrins activation using manganese on tolerance development to the analgesic effect of morphine was investi...

Determination of experimental Tumor Volume of a mouse using optical imaging system in different processing stages

Differentiation of Edematous, Tumoral and Normal Areas of Brain Using Diffusion Tensor and Neurite Orientation Dispersion and Density Imaging

Background: Presurigical planning for glioma tumor resection and radiotherapy treatment require proper delineation of tumoral and peritumoral areas of brain. Diffusion tensor imaging (DTI) is the most common mathematical model applied for diffusion weighted MRI data. Neurite orientation dispersion and density imaging (NODDI) is another mathematical model for DWI data modeling.Objective: We stud...

Preliminary imaging studies of [61Cu]diacetyl-bis (N4-methylthiosemi-carbazone) in normal and hypoxic tumor models

  Introduction: [61Cu]diacetyl-bis(N4-methylthiosemicarbazone) ([61Cu]ATSM) is a well-established hypoxia imaging tracer with simple production and significant specifity. In this work the accumulation of the tracer is studied in wild-type, necrotic and hypoxic fibrosarcoma tumors. Methods: [61Cu]ATSM was prepared u...
