Glucocorticoids (GCs) are frequently used for the suppression of inflammation in chronic inflammatory diseases. Excessive GCs usage is greatly associated with several side effects, including gingival ulceration, the downward migration of the epithelium, attachment loss and disruption of transeptal fibers. The mechanisms underlying GCs-induced impairments in gingival tissue remains poorly understood. Mitochondrial dysfunction is associated with various oral diseases, such as chronic periodontitis, age-related alveolar bone loss and hydrogen peroxide-induced cell injury in gingival...

BACKGROUND: Despite guidelines for preoperative invasive mediastinal staging (IMS) for non-small cell lung cancer (NSCLC), concordance with guidelines and whether the use of these guidelines results in expected frequency of lymph node metastases has not been evaluated. Our objectives were to determine guideline concordance, reasons for nonconcordance, and, in patients who did not receive IMS, to determine the use of operative nodal sampling and final pathologic staging. METHODS: Patients who had a resection for NSCLC between 2010 and 2012 were identified from the Institutional Cancer Registry...

We have reported that excessive nitric oxide (NO), like other reactive oxygen species (ROS), causes a decrease in cytochrome c oxidase (CCO) activity and ATP levels (mitochondrial damage) resulting in lens opacity. In addition, previous reports have shown that oxidative stress caused by ROS enhances amyloid β (Aβ) production in mammalian lenses, and that Aβ1-42 stimulates inducible nitric oxide synthase (iNOS) promoter activity. Based on these reports, we investigated the relationship between NO and Aβ1-42 production in human lens epithelial (HLE) cells...

In this investigation, an enzyme catalyzed process was optimized to prepare methyl esters from crude Citrullus colocynthis oil (CCO). Novozym 435 was used to synthesize biodiesel by transesterification of CCO with methanol. Use of tert-butanol as a reaction medium eliminated negative effects caused by excess methanol and formation of glycerol byproduct. Several variables affecting the Citrullus colocynthis methyl ester (CCME) yield including lipase quantity, water content, methanol/oil mole ratio, reaction temperature, reaction medium composition, and reaction time were optimized...

Oregon's coordinated care organizations (CCOs) are an integral part of a massive statewide reform that brings accountable care to Medicaid. CCOs are regional collaboratives among health plans, providers, county public health, and communitybased organizations that administer a single global budget covering physical, mental, and dental healthcare for low-income Oregonians. CCOs have been given freedom within the global budget to implement reforms that might capture efficiencies in cost and quality. For this study-fielded between 2012 and 2015-we traced the path of the global budget through the interior structures of two of Oregon's most promising CCOs...

Transcranial infrared laser stimulation (TILS) is a noninvasive form of brain photobiomulation. Cytochrome-c-oxidase (CCO), the terminal enzyme in the mitochondrial electron transport chain, is hypothesized to be the primary intracellular photoacceptor. We hypothesized that TILS up-regulates cerebral CCO and causes hemodynamic changes. We delivered 1064-nm laser stimulation to the forehead of healthy participants ( n = 11), while broadband near-infrared spectroscopy was utilized to acquire light reflectance from the TILS-treated cortical region before, during, and after TILS...

120 Background: Radiation treatment (RT) is essential to cancer management, contributing to cure and symptom control. With increasing cancer incidence and treatment complexity, health systems must adapt to ensure patients (pts) receive the highest quality of care. METHODS: With the objective of ensuring equitable access to high-quality, safe care, Cancer Care Ontario (CCO), a provincial government agency, identified provincial variability in RT activities. As a result, CCO prioritized 3 quality initiatives over the past 7 years: 1) Access to Intensity Modulated RT (IMRT) (2008-2013); 2) Peer Review of RT plans due to increasing RT planning complexity and the existence of high-profile RT errors (2012-present); and 3) Ensuring equitable access to RT (RT Utilization) (2014-present)...

163 Background: Cancer screening detects pre-cancerous changes, or cancer at an early stage when there is a better chance of treating it successfully. Research shows that that physician encouragement improves the odds of patients getting screened. Furthermore, systematic reviews demonstrate that efforts to encourage screening can be more effective through telephone reminders when compared to other methods of outreach. Electronic Medical Records (EMRs) are a powerful tool for the coordination, recording, monitoring and reporting of patient care in primary care...

38 Background: One of the challenges facing Ontario relates to managing the rising costs of cancer drug treatments. The annual growth rate of cancer drug spending has increased by 10-20% since 2010, exceeding other therapeutic categories and is expected to continue to grow significantly faster than expenditures in other areas. Paradoxically, the price of a drug seems to have little relation to its demonstrated efficacy ( http://www.asco.org/practice-research/cancer-care-america-2015/focus-cost ). The Cancer Quality Council of Ontario (CQCO) and Cancer Care Ontario (CCO) embarked on a journey to systematically address this challenge...

220 Background: Chemotherapy induced nausea and vomiting (CINV) remains one of the most feared treatment-related toxicities in cancer patients. CINV has been shown to decrease quality of life and to increase dose modifications and unplanned hospital visits. Cancer Care Ontario (CCO) and the American Society of Clinical Oncology (ASCO) updated their CINV guidelines in 2013. These changes included a reclassification of many regimens from moderate (MEC) to highly emetogenic (HEC) and a decrease in the duration of serotonin inhibitors (5HT3i)...
