BACKGROUND Although direct nose-to-brain drug delivery has multiple advantages, its application is limited by the extremely low delivery efficiency (<1%) to the olfactory region where drugs can enter the brain. It is crucial to developing new methods that can deliver drug particles more effectively to the olfactory region. MATERIALS AND METHODS We introduced a delivery method that used magnet...

background : in the recent decade, due to the overwhelming importance of health and prevention of diseases, nurses, having the most number of the health care team, are acting in any positions of the health care delivery system; because nursing have a key role in promotion of health and health care everywhere. the objective of this research was to study the desired positions of nursing in the he...

Sensor networks are wireless adhoc networks where all the nodes cooperate for routing messages in the absence of a fixed infrastructure. Non-flooding, guaranteed delivery routing protocols are preferred because sensor networks have limited battery life. Location aware routing protocols are good candidates for sensor network applications, nevertheless they need either an external location servic...

background: aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (vmat/rapidarc) using 2d planar dosimetry, dynalog files and compass 3d dosimetry system. materials and methods: pre-treatment quality assurance of 10 gated vmat plans was verified using 2d array and compass 3d dosimetry system. advantage of compass over 2d planar is that it provides the clin...

Among Many fundamental communication primitives in wireless ad hoc network, flooding in wireless ad hoc network reduces the number of transmission in network and it plays a significant role in which every node transmits the message after receiving it for the first time. To successfully reducing the number of transmissions of broadcast that are required to achieve full delivery and constant appr...

extract  this article is about sports training that reduce pain after cesarean delivery. this method not only for women but also for other women and men who have abdominal surgery is beneficial. this method is based on relaxation , facilitate deep breathing and after surgery coughing. after that, some advices is given to patients for pain relief.   exercises to relax the muscles:   naturally af...

Ultrasound may play an important role in the management of labor and delivery. Induction of labor is a common obstetric intervention, performed in about 20% of pregnancies. Pre-induction cervical length, measured by transvaginal sonography, has been shown to have a significant association with the induction-to-delivery interval and the risk for cesarean section. In the management of labor there...

abstract background: a major problem of the first moments of childbirth, especially in “prolonged labor,” is perinatal asphyxia which necessitates neonatal resuscitation. this study aimed at evaluating the alert line of the partogram in recognizing the need for neonatal resuscitation 20–30 s after delivery. materials and methods: 140 full‑term pregnant women were kept under surveillance through...
