nanotechnology is the study of manipulating matter on an atomic and molecular scale. generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension size from 1 to 100 nanometers .  carbon nanotubes have great potentials for novel applications in industry, drug delivery system and many other uses. in this work after purification, multiwa...

gene therapy is in its development stage as a novel method for cancer treatment. liposomes look promising as gene delivery vectors; however, investigations have shown that these vesicles are not doing well in some cases. it was decided here to investigate the possibility of augmentation of liposomal gene delivery by chemical penetration enhancers.cationic liposome containing antisense oligonucl...

background: labor pain is one of the most severe pains which has ever evaluated and its fear is one of the reasons women wouldn't go for natural delivery. considering different factors which affect experiencing pain, this study aimed to explain women's experiences of pain during childbirth. methods: this was a qualitative phenomenological study. the study population was composed of 14 women in ...

background and objectives: preterm labor is a serious problem in obstetrics, accounting for 70% of perinatal mortality. high sensitive c - reactive protein (hs-crp) is a sensitive marker of inflammation. our aim in this study was to determine amniotic fluid hs-crp concentration and its correlation with pre-term delivery.   materials and methods: this prospective study was conducted on 90 pregna...

the application of chemotherapy in cancer treatment has been limited due to cause side effects such as toxicity against normal cells and drug resistance. in recent years, numerous studies have been focused on using natural products with chemotherapeutic drugs to enhance therapeutic efficiency and reduce cytotoxicity. on the other hand, encapsulation of drugs into nanoparticles (nps) can improve...

In hierarchical reliable multicast schemes, the number of repair proxies and their locations influence the delivery delay. Low delivery delay is essential for the transmission of real time media. In this paper, we propose a method to decide optimal locations of repair proxies that minimizes the mean delivery delay of all receivers in heterogeneous network using a dynamic programming approach. T...
