introduction: neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. pora is a major component of the outer membrane of n. meningitidis and functions as a cationic porin. this study aimed to clone and determine the expression of pora as the first step for producing a proper antigen in a vaccine study against n. meningitidis. methods: an approximately ...

solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...

objective: resistance of metastatic lymph nodes (lns) to high dose i-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. we evaluated the role of f-18 fdg pet/ct in the prediction of resistance to high dose i-131 therapy in patients with papillary thyroid cancer. methods: the subjects were 307 patients who underwent total or near total thyroidectomy fol...

This study is carried out to estimate the potential evapotranspiration (PET) and crop coefficient (Kc) for Wheat, BL 3235 variety. A lysimeter is installed to estimate PET at the experimental farm of Agricultural Research Center of Bhairahawa, which is located in western part of Nepal. The Blaney-Criddle formula is used to estimate the Kc for wheat. The estimated values of PET and Kc for wheat ...

As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...

BACKGROUND We compared PET/MRI with PET/CT in terms of lesion detection and quantitative measurement to verify the feasibility of the novel integrated imaging modality for oncological applications. METHODOLOGY/PRINCIPAL FINDINGS In total, 285 patients referred to our PET/CT center for oncological indications voluntarily participated in this same-day PET/CT and PET/MRI comparative study. PET/C...

This study has investigated the creep properties of asphaltic concrete modified with different dosages of waste polyethylene terephthalate (PET) in two different ranges of size. Uniaxial dynamic creep test at 40°C was conducted on the cylindrical specimens of the mixtures. The load was applied in two different frequencies of 0.5 and 5Hz. Creep test results showed that the accumulated strain und...
