BACKGROUND Data suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resi...
Tomographic techniques play a crucial role in imaging methods such as transmission electron microscopy (TEM) due to their unique capabilities to reconstruct three-dimensional object information. However, the accuracy of the two standard tomographic reconstruction techniques, the weighted back-projection (W-BP) and the simultaneous iterative reconstruction technique (SIRT) is reduced under commo...
PURPOSE To provide a first evidence-based review of the literature on the role of fluorine-18-fluorodeoxyglucose positron emission tomography and positron emission tomography/computed tomography (FDG-PET and PET/CT) in patients with colorectal liver metastases (CRLM) undergoing selective internal radiation therapy (SIRT) with yttrium-90 ((90)Y) microspheres. METHODS A comprehensive computer l...
To clarify how the osteoarthritis (OA)-induced catabolic factor interleukin (IL)-1β affects chondrocyte energy metabolism, and especially to define the downstream pathway linking nicotinamide adenine dinucleotide (NAD)dependent deacetylase Sirtuin-1 (Sirt-1) to energy metabolism in OA chondrocytes. Human chondrocytes were isolated from articular cartilage samples of patients with OA. The level ...
Sir2 is a NAD+-dependent protein deacetylase that extends lifespan in yeast and worms. This study examines seven human proteins homologous to Sir2 (SIRT1 through SIRT7) for cellular localization, expression profiles, protein deacetylation activity, and effects on human cell lifespan. We found that: 1) three nuclear SIRT proteins (SIRT1, SIRT6, and SIRT7) show different subnuclear localizations:...
Primary and secondary liver malignancies are common and associated with a poor prognosis. Surgical resection is the treatment of choice; however, many patients have unresectable disease. In these cases, several liver directed therapies are available, including selective internal radiation therapy (SIRT). SIRT is a multidisciplinary treatment involving nuclear medicine, interventional radiology ...
Sepsis-induced organ failure is the major cause of death, and is characterized by a massive dysregulated inflammatory response. The present study was to determine whether interleukin 6 (IL-6) expression was increased in sepsis rats and the roles of IL-6 in the damage of cardiac, liver and renal function in the sepsis rats. Sepsis rat models were elicited by intravenous injection of LPS. The mRN...
Presenter: Armeen Mahvash MD | The University of Texas Anderson Cancer Center Background: HCC is often diagnosed when potentially curative resection or transplantation not feasible. Selective internal radiation therapy (SIRT) with 90Y resin microspheres (SIR-Spheres®) an established locoregional treatment option for unresectable regulatory approval outside the USA. SIRT has potential to deliver...
Recently, a survey by the Centers for Disease Control and Prevention (CDC) reported that nearly 90% of U.S. adult smokers began smoking at the age of 18. This demonstrates that the exposure to environmental tobacco smoke (ETS) of youngsters today is changing from passive smoking to active smoking (direct inhalation of tobacco). In the current study, an investigation of ETS exposure in young C57...
The past few decades have witnessed a furious attention of scientific community toward identifying novel molecular factors and targets that could be exploited for drug development for cancermanagement.One such factor is the sirtuin (SIRT) family of nicotinamide adenine dinucleotide (NADþ)-dependent deacetylases. The role of SIRTs in cancer is extremely complex, with dichotomous functions depend...
