 OBJECTIVES The purpose of this study was to evaluate the effects of universal adhesives with different photo-initiator systems applied in etch-and-rinse (ER) and self-etch (SE) modes on dentin interaction (push-out bond strength [PBS], nanoleakage [NL], and degree of conversion [DC] within the hybrid layer) in the different root thirds after fiber post cementation. METHODS AND MATERIALS Roots of endodontically prepared human premolars were randomly divided into six groups according to one of three adhesive systems (Scotchbond Universal [SBU], Ambar Universal [AMB], and Ambar Universal APS [AMB-APS]) and two adhesive strategies (ER and SE) for each system.  https://www.selleckchem.com/products/azd9291.html  Posts were cemented, and PBS was tested at 0.5 mm/min. The NL was evaluated by scanning electron microscopy. DC was measured using micro-Raman spectroscopy. The data were analyzed by three-way analysis of variance and Tukey tests (α=0.05). RESULTS AMB-APS showed similar performance in all root thirds (p>0.05) and higher values of DC, especially in the apical third (p less then 0.0001). AMB and SBU showed the lowest values in the apical third (p less then 0.0001). CONCLUSIONS The APS photo-initiator system contained in universal adhesives is a feasible alternative for improving radicular bonding procedure.Aim To determine the potential of mesenchymal stem cells (MSC) for corneal epithelial regeneration in vitro. Materials & methods Bone marrow MSC (BM-MSC) and adipose tissue MSC were analyzed for corneal epithelial and mesenchymal markers, using limbal stem cells and corneal cells as controls. MSC with better potential were cultured with specific mediums for epithelial induction. Transepithelial electric resistance and wound healing assay with human corneal epithelial cells were performed. Results BM-MSC showed better potential, increased corneal markers, and higher transepithelial electric resistance values when induced with limbal epithelial culture medium. Induced BM-MSC promoted better wound healing of human corneal epithelial cells by paracrine secretion. Conclusion BM-MSC has potential for corneal epithelial induction in a protocol compatible with human application.Refractory gout (RG) has been increasingly recognized to be a major problem in clinical care. Patients diagnosed with RG have been assumed to be non-adherent, or under-dosed, to the greater part. In a minority, pathophysiological mechanisms have been discussed. During the last two decades, however, none of the studies differentiated non-adherence from impaired response to drug treatment. A definition of adherence has been proposed in the case of allopurinol treatment (oxipurinol in serum, >20 µmol/l), which would seem to confirm a dose of about 50 mg/d being taken by the patients. Guidelines for treating gout published by national or international rheumatology societies do provide very little, if any, information on how to evaluate patients with RG. Coinciding with the development of the xanthine oxidase inhibitor, febuxostat, a moderate increase in the number of publications on RG was observed, with a sharp rise following after its approval for clinical use. It was demonstrated recently that intensive training and supervision of patients with gout resulted in very low numbers of patients not reaching treatment targets. It should be remembered that allopurinol, is an ideal instrument for differentiating non-adherence from true impaired response. We conclude that, apart from very rare patients, needing confirmation of such a diagnosis by metabolic ward studies, RG does not exist, and with close to hundred percent, treatment failure is due to patient and physician behavior.Alcohol use is associated with poorer smoking cessation-related outcomes, and smokers with elevated levels of worry experience greater smoking cessation problems. Yet, little is known about the explanatory mechanisms that may underlie the relationship between trait worry and hazardous drinking among smokers. Therefore, this study explored the explanatory roles of coping and conformity drinking motives in the relationship between trait worry and hazardous drinking outcomes including alcohol consumption, alcohol problems, maximum number of drinks, and the number of prior alcohol quit attempts among treatment-seeking smokers. Participants included 377 treatment-seeking smokers who consumed at least one alcoholic drink in the last year (48% female; 86.2% Caucasian; Mage = 34.83 years, SD = 13.38). Results showed a significant indirect effect of trait worry through coping-related drinking motives in relation to alcohol consumption, alcohol problems, maximum number of drinks, and number of prior drinking quit attempts.  https://www.selleckchem.com/products/azd9291.html  These findings were evident after controlling for gender, cigarette dependence, and current psychopathology. These findings suggest that coping drinking motives are one mechanism that may explain the relation between trait worry and hazardous drinking outcomes among treatment-seeking smokers.Mild functional difficulties associated with cognitive aging may be reliably measured by coding "micro-errors" during everyday tasks, like meal preparation. Micro-errors made by 25 older adult and 48 younger adults were coded on four dimensions to evaluate the influence of 1) poor error monitoring; 2) goal decay; 3) competition for response selection when switching to a new subtask; and 4) interference from distractor objects. Micro-errors made by young adults under a dual task load also were analyzed to determine the influence of overall performance level. Older adults' micro-errors were observed when switching to a new subtask and to unrelated distractors. Slowed error monitoring and goal decay also influenced micro-errors in older adults, but not significantly more so than younger adults under the dual task. Interventions to reduce interference from distractors and to increase attention at critical choice points during tasks may optimize everyday functioning and preclude decline in older adults.Food insecurity, life events, and emotional eating can influence dietary patterns. However, their interaction among older adults requires further investigation. This mixed-method, interdisciplinary project included 7 focus groups and a cross-sectional survey (n = 55) to evaluate these factors among older adults (60-102 years of age) living in rural Ohio communities. Qualitative data highlighted critical life events, emotions and personal relationships, food insecurity, and learning how to do more with less, and resilience in dietary patterns. The majority of the participants were overweight or obese. Food insecurity, frequency of congregate meals, and age were associated with emotional eating. Attributes of diet quality correlated with emotional eating and food insecurity. Future work should address the unique needs of older adults by expanding food assistance programs, while including the older adult's perspectives with regard to life experiences, the value of social support, personal relationships, and honoring food preferences, particularly nutrient-dense foods.
