Introduction: Nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. Using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. X-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. These effects obey the LNT hypothesis that occur at lo...

at the present, many drugs are used for inhibition of uterine contractions, but the proportions of preterm labors are increasing. although magnesium sulfate is the most commonly prescribed parenteral tocolytic agent, but its optimal use has yet to be delineated. in this study a high-dose protocol for magnesium sulfate tocolytic therapy was compared with a low-dose regimen. one-hundred patients ...

Introduction: The study aimed to find the low dose effect gamma ray on some hematological parameters in male albino rats obtained from the Mosul University, IRAQ, and also studied the radioprotective effect of black seed oil on the hematological parameters. Material and Methods: The system is made of 241Am as gamma source .The...

Introduction: Cyclophosphamide (CP) is used for the treatment of various cancers. In spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. In the current study, we have investigated the adverse effects of CP on morphology and histology of testis rats. M...

Oral contraceptive pills have several side effects especially on the gastrointestinal tract and liver. Absorption of low dose (LD) pills by the vaginal route avoids the first pass of the steroids through these tracts and probably has fewer side effects. This study was a cohort study for evaluation of side effects and acceptability of LD pills administered by the vaginal route. In a clinical...

Using the recent excise tax increases at the state-level in the United States from 2000 to 2010, I estimate two-way fixed effects models of older adult smoking participation. I find that a one dollar increase in the excise tax reduces smoking participation by 2.5 percent for adults age 30 to 74. An investigation of the age distribution finds that results are sensitive to how older adult age gro...

The role of aspirin in women with infertility is controversial and the evidence is inconsistent; some studies have reported benefits in women undergoing IVF whilst others have not. An important gap in the literature was the question of when to start and when to stop aspirin and how long should aspirin be given for. In a 2007 systematic review on the effectiveness of aspirin on IVF outcomes invo...
