Objective: To assess the utility of 18F-PSMA-1007 PET/MRI in initial staging of intermediate- to high-risk prostate cancer (HRPCa).
Methods: A total of 46 patients with pathologically verified intermediate and/or HRPCa who underwent 18F-PSMA-1007 PET/MRI with dedicated pelvic high-resolution multiparametric MRI (mpMRI) were included.
Results: PET/MRI showed 100% sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and accuracy in detecting seminal vesicle (SV) and rectal invasion, versus 87.
Four fungal and one bacterial isolates were isolated from a liquid waste sample of Nuclear Material Authority. Those dried biomasses were screened for uranium (U) and thorium (Th) adsorption efficiency where the most potent isolate was identified according to sequence similarities and phylogenetic analysis as LBM 134 Using U or Th synthetic solutions many factors were investigated for controlling the biosorption process to conduct the optimum process conditions (the solution pH, contact time, elemental initial concentration, biomass dosage, and sorption temperature). was examined ESEM-EDX and the FTIR techniques before and after the sorption process, also the data were handled by different kinetics and isothermal models.

P53 is a tumor suppressor gene that contributes to apoptosis and cell cycle control. There is functional interaction between p53 and COX-2, which lead to abrogation of apoptosis and progression of malignancy.

Materials And Methods: Twenty-three female patients with suspected breast cancer recurrence by clinical, laboratory, or conventional imaging underwent both FDG-PET/CT and WB MR/DWIBS. WB FDG-PET/CT was performed using the standard technique.
Aim And Objectives: The aim of this study is to assess the added value of hybrid fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the evaluation of extranodal involvement in patients with lymphoma in comparison to contrast-enhanced CT (CECT).
Patients And Methods: All patients had lymphoma, proved by histopathological and immunophenotyping examinations. They underwent CECT and F-18 FDG PET-CT studies.
Khat chewing is a recreational habit known to pose major socio-economic and medical problems in countries of Southern Arabia and the Horn of Africa. Among other adverse health effects, khat chewing has been associated with an increased risk of myocardial infarction (MI) in heavy consumers. This study was carried out to examine the direct effects of Catha edulis extract on contractility of spontaneously contracting, isolated rabbit heart and to investigate its mechanism of action.
