the pomegranate seed oil (pso), containing 17-α-estradiol, is one of the newly found phytosterols with synergistic health effects on estrogen related physiological conditions. herein, pso was assessed for its potential improving effects on bone characteristics in a rat model of menopausal syndrome. three month old non-pregnant female wistar rats (n = 30) were either sham-operated (sham) or ovar...

background: gallium-66 (t1/2= 9.49 h) is an interesting radionuclide that has potential for positron emission tomography (pet) imaging of biological processes in intermediate to slow target tissue uptake. oxine has been labeled with this radioisotope in the form of [66ga]gallium chloride for its possible diagnostic properties. materials and methods: 66ga was produced in the 30 mev cyclotron (cy...

background: computed tomography (ct) is main contributor of population dose from diagnostic x-ray examinations. children are more radiosensitive than adults, thus optimization of ct examination in these patients is essential. the purpose of this study was to evaluate dose delivered to pediatric patients’ undergoing ct examination of the common examinations and also establishing local diagnostic...

Background: Compact cyclotrons are getting popular to fulfill enormous current demands of PET tracers. Aga Khan University Hospital, Karachi, Pakistan has acquired the first smallest footprint of BG-75 Generator for 18FDG-based PET/CT clinical imaging. We are sharing our experience of BG-75 in the first year (December 2015-November 2016) after commissioning. Mater...

Hepatosplenic candidiasis is a fungal infection, which mostly affects patientswith hematologic malignancies such as leukemia.

wisdom tooth operations are sometimes accompanied by complications. this case report shows complications during upper jaw third molar removal. expectable problems during oral surgery should be planned to be solved in advance. displacement of the third molar during oral surgeries as a considerable complication is rarely discussed scientifically. a good design of flap, adequate power for extracti...

course applicable to other parts as well; but, it is in chest radiology that the method is of particular use. In his introduction the author points out that one of the main sources of difficulty in interpreting an ordinary skiagram of the chest is the superimposition of the shadows of the bony framework and blood vessels, bronchioles and alveoli. It is not generally appreciated, for instance, t...
