A novel mechanism has been defined for controlling per-oxisome proliferator-activated receptors γ (PPARγ) activity in response to thiazolidinedione (TZD) ligands, in which deacetylation of PPARγ by SirT1 remodels the transcriptional complex. This change favors expression of genes associated with increased energy use and insulin sensitization in white adipose tissue (WAT), and is required for a ...

Background and Objective: In neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. Pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. This study was conducted to determine the effects of hydrogen peroxi...

AIMS We previously demonstrated that resveratrol (RSV) administration causes cardiac stromal cell-derived factor (SDF)-1 upregulation and can enhance the mobilization of stem cells in mice with acute myocardial infarction (AMI). However, the upstream signal transduction involved in SDF-1 regulation in the setting of AMI and RSV administration remains unclear. Because RSV is a sirtuin 1 (SIRT1) ...

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 responder- non responder and hepatic- extra hepatic disease. METHODS The clinical and follow-up data of 124 patients who were ...

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...

Protein-protein interaction networks are useful for studying human diseases and to look for possible health care through a holistic approach. Networks are playing an increasing and important role in the understanding of physiological processes such as homeostasis, signaling, spatial and temporal organizations, and pathological conditions. In this article we show the complex system of interactio...

A 39 years old male patient with a history of an unresectable thymoma and synchronous liver metastases was referred tor our position. The patient had been originally treated with systemic chemotherapy followed by imatinib (Glivec) and sunitinib (Sutent). Since the therapeutic response was unsatisfactory, a gallium-68 ((68)Ga)-Dotatoc-positron emission tomography (PET) was performed and demonstr...
