Introduction: As a valuable imaging modality, Nuclear Medicine (NM) indications is raising in clinical practice. The remained portion administrated radioactive material in patients’ tissues is a critical issue, especially when the procedure is performed in hospitalized patients, where the non-radiation workers present. The aim of this study was evaluation the dose of non-radia...

In this study, the effect of chamomile extract on the ability of neonatal calves to absorb immunoglobulin G (IgG) was evaluated. An ethanolic extract of chamomile was obtained with the concentration of 111 mg/ml. Calves were randomly divided into four groups, each receiving one of four chamomile treatments; 1: low dose (LC; 5.5 mg/kg body weight; 2: moderate dose (MC; 11 mg/kg); 3: high dose (H...

Introduction: Stereotactic Gamma Knife radiosurgery has been widely used for treating brain tumors. The scattered radiation outside of treatment field (peripheral dose) can induce the secondary cancer to specific organ. This paper investigated the absorbed dose to eyes, thyroid, heart, lung, breast and colon using a Monte Carlo technique for Mird phantom. We also study the ef...

Acquired Megacolon is a rare disease that usually presents in elderly people and there have been only few reported cases in literature. In this article we report a 24-year-old woman who had referred with chronic intermittent epigastric pain from 4-5 years ago and also chronic constipation and distension of upper abdominal part. Clinical examinations and imaging studies (chest x-ray, barium enem...

Absorption of electrolytes and water from the human rectum was quantified by sequential sampling of physiological solutions instilled into the rectum and by the method of continuous intraluminal perfusion. The absorptive function of the rectum measured by the perfusion technique was also compared with that of the entire large intestine. The rectum did not absorb sodium, chloride, or water from ...

Background: Hysterosalpingography (HSG) is an indispensable tool for diagnosing infertility in females. The procedure exposes female reproductive organs to ionizing radiation as the genitals are irradiated during the process. Investigating patient absorbed dose during the procedures is essential for effective radiological protection of the patient. Objective: This study aims to investigat...

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhan...
