Gene targeting provides a powerful tool for dissecting gene function. However, repeated targeting of a single locus remains a practice mostly limited to unicellular organisms that afford simple targeting methodologies. We developed an efficient method to repeatedly target a single locus in Drosophila. In this method, which we term "site-specific integrase mediated repeated targeting" (SIRT), an...

Periodontal disease is one of the most prevalent chronic disorders worldwide. It is accompanied by inflammation of the gingiva and destruction of periodontal tissues, leading to alveolar bone loss. Here, we focused on the role of adipokines, which are locally expressed by periodontal tissues, in the regulation of catabolic gene expression leading to periodontal inflammation. The expression of t...

Background: The aim of this study was to evaluate the success of selective intraarterial radionuclide therapy (SIRT) with Yttrium-90 (Y-90) microspheres in liver metastases of different tumors. We also interpreted the contribution of SIRT to survival times according to respondernon responder and hepaticextra hepatic disease. Methods: The clinical and follow-up data of 124 patients who were refe...

BACKGROUND The aim of this study was to evaluate the success of selective intraarterial radionuclide therapy (SIRT) with Yttrium-90 (Y-90) microspheres in liver metastases of different tumors. We also interpreted the contribution of SIRT to survival times according to responder- non responder and hepatic- extra hepatic disease. METHODS The clinical and follow-up data of 124 patients who were ...

PURPOSE Selective Internal Radiation Therapy (SIRT) with 90yttrium (Y-90) is an increasingly used therapeutic option for unresectable liver malignancies. Nontarget embolization of extrahepatic tissue secondary to vascular shunting can lead to SIRT associated complications. Our aim was to assess whether extrahepatic shunts can reliably be diagnosed based on hepatic digital subtraction angiograph...

BACKGROUND The higher tolerated mean absorbed dose for selective internal radiation therapy (SIRT) with intra-arterially infused (90)Y microspheres compared to external beam therapy is speculated to be caused by absorbed dose inhomogeneity, which allows for liver regeneration. However, the complex liver microanatomy and rheology makes modelling less valuable if the tolerance doses are not based...

Introduction: Sirtuin 1 is a protein deacetylase that plays an important role in many cellular processes. The serum sirtuin 1 levels are higher in the polycystic ovary syndrome (PCOS) patients than the healthy subjects. The aim of this study was to assess the role of SIRT-1 rs7895833 polymorphism in the susceptibility of PCOS. Methods: This case-control study was done on 456 Iranian women fr...

Expectation Maximization (EM) and the Simultaneous Iterative Reconstruction Technique (SIRT) are two iterative computed tomography reconstruction algorithms often used when the data contain a high amount of statistical noise, have been acquired from a limited angular range, or have a limited number of views. A popular mechanism to increase the rate of convergence of these types of algorithms ha...
