Background: Evaluating and monitoring the performance of emergency departments (EDs) are steps in one of the most important processes to improving the efficiency of hospitals. Indicators such as patient wait time until being visited by a doctor, patient wait time from the order until admission, percentage of patients with a determined order, time of conversion of a patient’s co...

Objective(s): The current investigation was undertaken to evaluate the effects of 17β- estradiol (17β-ED) on the potential of the mesenchymal stem cells (MSCs) for modulation of immunity responses in an animal model of multiple sclerosis (MS).Materials and Methods: After isolation of MSCs, cells were cultured in presence of 100 nM 17β-ED for 24 hr. Modeling of experimental autoimmune encephalom...

RESUMEN Los macrófagos desempeñan un papel fundamental en el reconocimiento y eliminación de patógenos, y en el mantenimiento de la homeostasis tisular. La elevada heterogeneidad fenotípica y funcional de los macrófagos está condicionada por el medio extracelular, y ha conducido a la definición de estados de activación (clásica, alternativa) en los que los macrófagos muestran actividades funcio...

Introduction: In digital radiography, radiographers tend to increase exposure factors to acquire an acceptable image quality thereby increasing radiation dose to patients.  Regarding this, the present study aimed to re-evaluate the exposure parameters and to ascertain the entrance surface dose (ESD) and effective dose (ED) of posterior-anterior (PA) chest, abdomen, and anterior-posterior (AP) l...

A graph G is a k-dot product graph if there exists a vector labelling u : V (G)→ Rk such that u(i)Tu(j) ≥ 1 if and only if ij ∈ E(G). Fiduccia, Scheinerman, Trenk and Zito [4] asked whether every planar graph is a 3-dot product graph. We show that the answer is “no”. On the other hand, every planar graph is a 4-dot product graph. We also answer the corresponding questions for planar graphs of p...

Article Outline Materials and Methods Conclusion References Vitae ED overcrowding has been gaining national attention in recent years. It is becoming apparent that, like the canary in the coal mine, ED conditions are emblematic of systemwide health care failures: too many patients, not enough room, inadequate resources, and

erectile dysfunction (ed) is an important impediment to quality of life. diabetes mellitus is one of the most common causes of ed. however, it has been one of the most neglected complications of diabetes mellitus. our objective was to study the prevalence of ed and its risk factors in iranian diabetic men. during 2002-2004, 700 diabetic men aged 20-69 years were interviewed to report on their e...
