background: we aimed to identify the role of sirt 6 gene polymorphism rs350846 in human longevity. methods: sirt 6 c/g genotypes were determined using taqman snp genotyping assays in 169 long-lived inhabitants (lg group aged 90-110 yr), 158 healthy internal controls (internal control group; aged 26-82 yr) and 176 healthy external controls (external control group; aged 20-82 yr) without a family...
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...
BACKGROUND Sirtuin (SIRT) proteins are class I histone deacetylases displaying gene regulatory functions in inflammatory, cancer, and metabolic diseases. These SIRT actions involve the nuclear factor κ B and its inhibitor I κ B pathway. However, the regulation of SIRT in vivo is still unclear. MATERIAL AND METHODS In a human endotoxemia model, 20 healthy male subjects received an intravenous ...
Background. Nonresectable neuroendocrine tumour (NET) liver metastases respond poorly to most widely available and used therapies. Selective Internal Radiation Therapy (SIRT) is becoming recognized as a new modality for selectively treating non-resectable liver tumours. This paper presents an experience of 14 patients with non-resectable NET liver metastases treated with SIRT. Methods. Between ...
PURPOSE We sought to report outcomes and toxicity in patients with hepatocellular carcinoma (HCC) who received resin yttrium-90 selective internal radiation therapy ((90)Y-SIRT) and to identify factors associated with declining liver function. METHODS Patients treated with (90)Y-SIRT were retrospectively evaluated. Radiographic response was assessed using RECIST 1.1. Median liver progression-...
BACKGROUND SIRT 1, as a class III histone deacetylase (HDAC), is implicated in the initiation and progression of malignancies. However, the association of SIRT 1 with tumorigenesis or progression of pancreatic ductal adenocarcinoma (PDAC) is not clear. MATERIAL AND METHODS In our study we investigated SIRT 1 expression in PDAC samples and evaluated the association of SIRT 1 level with the clini...
Abstract Background Osteoarthritis (OA) is a chronic degenerative disease that suppresses middle-aged and older people worldwide. Silent information regulator 1(SIRT-1) associated with several age-related diseases, such as cardiovascular neurodegenerative diseases tumors, etc. The protective role of SIRT-1 in bone joint has become increasingly well known. Objective To explore the relationship b...
Abstract Background 99m Tc-macroaggregated albumin ( Tc-MAA) scintigraphy is utilized in treatment planning for Yttrium-90 90 Y) Selective Internal Radiation Therapy (SIRT) of liver tumors to evaluate hepatopulmonary shunting by calculating the lung shunt fraction (LSF). The purpose this study was if LSF calculation using SPECT/CT instead planar gamma camera imaging more accurate and can potent...
332 Background: Liver-directed therapies can be beneficial in reducing morbidity and mortality in patients with metastatic neuroendocrine tumors (mNETs). We compared the clinical outcomes of patients treated with hepatic artery embolization/chemoembolization (HA(C)E) or selective internal radiation therapy (SIRT) with SIR-Spheres at our institution over the last ten years. METHODS Medical rec...
Abstract Selective internal radiation therapy (SIRT) is an emerging therapeutic modality in patients with unresectable hepatocellular carcinoma or liver metastases. However, complications can occur due to migration of microspheres such as gastrointestinal ulcer, cholecystitis, bleeding, pancreatitis, and many others. A 50-year-old woman stage IV breast cancer who underwent radioembolization for...
