sirtuin1 (sirt1) is an enzyme that deacetylates histones and several nonhistone proteins including p53 during stress and plays an important role in the survival of tumor cells. hereby, this study describes the potency of salermide as a sirt1 inhibitor to induce apoptosis in the mcf-7 and mrc-5 cell lines. mcf7 and mrc-5 cell lines were cultured in rpmi-1640 and treated with or without salermide...

background: magnetic resonance cholangiography (mrc) has gained popularity for diagnosing primary sclerosing cholangitis (psc). we determined the accuracy of mrc compared with endoscopic retrograde cholangiography (erc) for diagnosing psc. materials and methods: this retrospective case-control study was conducted on patients referred to an outpatient gastroenterology clinic from 2001 to 2013. p...

Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...

In this paper, an Alamouti-coded decode-and-forward protocol with optimum relay selection for three-user one destination cooperative communications is investigated. Particularly, we design the new protocol that allows the source node retransmitting the signal to the destination node at the same time as the relay node forwarding the received signal to the destination node with an Alamouti coding...

Trust Establishment is one of the significant resources to enhance the scalability and reliability of resources in the cloud environment. To establish a novel trust model on SaaS (Software as a Service) cloud resources and to optimize the resource utilization of multiple user requests, an integrated software trust estimator with multi-user resource competence (IST-MRC) optimization mechanism is...
