Production of reactive oxygen species (ROS) can be accelerated under various biotic and abiotic stresses causing lipid peroxidation, protein degradation, enzyme inactivation, and DNA damage. Superoxide reductase (SOR) is a novel antioxidant enzyme from Pyrococcus furiosus and is employed by this anaerobic hyperthermophilic archaeon for efficient detoxification of ROS. In this study, SOR was int...

A results are mixed. Studies of standing orders tend to examine their effect on compliance with preventive interventions for chronic disease rather than disease outcomes. In the ambulatory setting, they improve rates of influenza vaccination (strength of recommendation [SOR]: C, consistent cohort studies measuring vaccination rates), pneumococcal vaccination (SOR: C, consistent randomized contr...

The SOR (sulphur oxygenase reductase) is the initial enzyme in the sulphur-oxidation pathway of Acidianus ambivalens. Expression of the sor gene in Escherichia coli resulted in active, soluble SOR and in inclusion bodies from which active SOR could be refolded as long as ferric ions were present in the refolding solution. Wild-type, recombinant and refolded SOR possessed indistinguishable prope...

The aim of the present study was to compare the effectiveness of transarterial chemoembolization (TACE), TACE combined with Jie-du granules (JD), and TACE combined with sorafenib (SOR) for treating patients with unresectable hepatocellular carcinoma (HCC). For this purpose, we conducted a retrospective analysis of data from 266 consecutive patients with unresectable HCC who underwent TACE treat...

The superoxide radical O(2)(-.) is a toxic by-product of oxygen metabolism. Two O(2)(-.) detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H2O2 as a reaction product. Recently, the SOR active site, a ferrous iron in a [Fe(2+) (N-His)(4) (S-Cys)] pentacoordination, was shown to have the ability to form a complex with the organometal...

BACKGROUND AND OBJECTIVE To evaluate outer retinal changes present on spectral-domain optical coherence tomography (SD-OCT) in eyes pre- and post-silicone oil (SiO) removal (SOR). PATIENTS AND METHODS Retrospective case series of patients who underwent pars plana vitrectomy with SiO instillation and had SD-OCT completed pre- and post-SOR. SD-OCT parameters included presence of subretinal flui...

Sorafenib (SOR), a vascular endothelial growth factor receptor (VEGFR) inhibitor, is in wide clinical use for the treatment and prevention of liver cancer. However, extended SOR administration for hepatocellular carcinoma (HCC) induces drug resistance thereby limiting its efficacy and highlighting the need for improved therapeutic strategies. It has previously been demonstrated that knockout of...

هدف: کبد از حساس‌ترین بافت‌های هدف فشار اکسایشی ناشی تمرین می‌باشد و آمینوترانسفراز‌های کبدی، شاخص‌های حساسی برای تعیین آسیب دیدگی سلول‌های کبدی هستند. پژوهش حاضر با مقایسه تأثیر هشت هفته TRX مقاومتی سنتی بر برخی آنزیم‌های (آسپارتات آمینو ترانسفراز آلانین ترانسفراز) در زنان غیرفعال انجام گرفت.روش ­ها: این که به روش نیمه تجربی شد، 28 دختر میانگین سن41/1±07/21 سال شاخص توده بدن 25/4±52/22 کیلوگرم...

Anxiety disorders and sensory over-responsivity (SOR) are common in children with autism spectrum disorders (ASD), and there is evidence for an association between these two conditions. Currently, it is unclear what causal mechanisms may exist between SOR and anxiety. We propose three possible theories to explain the association between anxiety and SOR: (a) SOR is caused by anxiety; (b) Anxiety...
