Breast cancer is the most common malignancy, and it is also the major cause of cancer-related deaths of women worldwide. Breast cancer treatment involves surgery, chemotherapy, radiation therapy, or combination therapy, and novel strategies are needed to boost the oncologic outcome. The non-metabolizable glucose analogue, 2-deoxy-D-glucose (2-DG) which(More)
Radio-protectors are agents that protect human cells and tissues from undesirable effects of ionizing radiation by mainly scavenging radiation-induced free radicals. Although chemical radio-protectors diminish these deleterious side effects they induce a number of unwanted effects on humans such as blood pressure modifications, vomiting, nausea, and both(More)
BACKGROUND Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. OBJECTIVE The majority of these tumors are benign; however, sometimes they tend to(More)
In the present study, a series of multifunctional drug delivery systems based on mesostructured hydroxyapatite coating and superparamagnetic nanoparticles with pH-responsive characters was prepared. The structure of each new synthesized nanoscale composite was fully characterized by XRD, FTIR, TEM, VSM and BET. The results showed a good ordered(More)
Breast cancer is the most frequent cancer in women and it is the main reason of cancer-related deaths of women worldwide. Different types of breast cancer diagnostic examinations are also available, such as mammography, MRI, biopsy, ultrasound and molecular imaging. Radionuclide-based imaging methods including SPECT and PET are useful in early diagnosis and(More)
INTRODUCTION Nanoparticles are promising as a new approach to enhance chemo- radiotherapy efficiency in breast cancer mainly via targeted therapy. MATERIALS & METHODS SKBR3 and T47D breast cancer cells were treated with superparamagnetic mesoporous hydroxyapatite nanocomposites (SPmHANs)conjugated with 1 μM doxorubicin and 0.5 mM 2-Deoxy-d-Glucose and(More)
PURPOSE Two-deoxy-D-glucose (2DG) causes cytotoxicity in the cancer cells by disrupting the thiol metabolism, and MLN4924 inactivates the SCF E3 ligase and so causes the accumulation of its substrates which trigger apoptosis and hence might enhance the efficiency of radiotherapy and overcame on the radioresistance of the cancer cells. MATERIALS AND(More)
BACKGROUND Acquiring a high quality image has assigned an important concern for obtaining accurate diagnosis in nuclear medicine. Detector is a critical component of Single Photon Emission Computed Tomography (SPECT) imaging system for giving accurate information from exact pattern of radionuclide distribution in the target organ. The images are strongly(More)
INTRODUCTION Human double minute2 (hdm2) level increases in most human malignancies. Therefore, inhibition of tumor growth and also induction of radiosensitivity may be provided by hdm2 inhibitors. The effects of hdm2-siRNA on hdm2 protein expression, cell apoptosis rate, and radiosensitivity of human esophageal squamous cell carcinoma (ESCC) were studied.(More)
