background: the aims of the study are to determine the radioactivity concentrations of 226ra, 238u, 232th and 40k in vegetables of a recently found high background radiation area of south-eastern part of bangladesh and to detect the radiological risks to human from intake of these vegetables. materials and method: 10 plant samples were collected randomly from different locations of the study ar...

introduction exposure to chronic levels of ionizing radiation could be detrimental to health even at very low doses. calabar free trade zone (cftz) was established to promote export business in nigeria and it is yet to produce exposure data of the zone. materials and methods the zone was divided into three categories depending on the type of business. category a had facilities with manufacturin...

background: activity concentrations of 40k, 226ra and 228ra were measured in some sachet drinking water samples produced in nigeria. materials and methods: the measurement was done by using high-purity germanium (hpge) detector (canberra industries inc.). the measured activity concentrations for 226ra (u-series) and 228ra (thseries) were used with their ingested dose conversion factors to estim...

background marketing new radiography devices necessitates documenting their absorbed x-ray doses. since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed. objectives the new devices were compared to the promax three dimensional (3d) scanner at two fields of view (fov) in nine critical head and neck tissues and org...

background: x-ray computed tomography (ct) examinations deliver a significant amount of radiation doses to patients comparing to conventional radiography examinations. the objective of the current study was to analyze and investigate the average patient received dose from axial and spiral ct exams in a medical imaging center. material and methods: in this study, the patient imaging technique, w...

This study investigated the anticonvulsant activity of a new phthalazine tetrazole derivative, QUAN-0808 (6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine), in the mouse maximal electroshock (MES) seizure model. The neurotoxicity of QUAN-0808 was investigated using the rotarod neurotoxicity test in mice. QUAN-0808 exhibited higher activity (median effective dose, ED(50) = 6.8 mg/kg) and lower ne...

Introduction: Nowadays, we are witnessing an exponential use of interventional radiology techniques in different communities. After CT, interventional techniques are the second factor of increasing patients’ doses in different societies. Measuring patient doses from aforementioned methods has been recommended by many radiation protection professional organizations such as ICRP...

Purpose: To evaluate the radiation attenuation properties of PC-ISO, a bio-compatible, sterilizable 3D printing material and its suitability for customized gynecologic (GYN) brachytherapy 15 applicators. Method: A custom radiochromic film dosimetry apparatus was 3D-printed in PC-ISO. The apparatus contained a single catheter channel and a slit to hold a radiochromic segment. A brachytherapy dos...

Abstract Background Acute myocardial infraction (AMI) is a leading cause of morbidity. As anti-diabetic drugs affect the cardiovascular risk diabetic patients independent their glucose lowering effect, this study was aimed to explore cardioprotective effects metformin, sitagliptin and dapagliflozin on electrocardiogram (ECG) changes, IL-1β, troponin I, caspase 3 in isoprenaline (ISO) induced MI...
