    ASSESSMENT OF ORAL HEALTH IN PERITONEAL DIALYSIS PATIENTS WITH AND WITHOUT DIABETES MELLITUS
    (Multimed Inc, 2012) Eltas, Abubekir; Tozoglu, Ummuhan; Keles, Mustafa; Canakci, Varol
    The incidence of chronic renal failure continues to rise worldwide, and although the oral and dental changes in individuals with this condition have been examined, investigations with diabetic peritoneal dialysis (PD) patients are limited. We therefore examined salivary pH, dry mouth, taste change, and mucosal ulceration in diabetic and nondiabetic uremic patients receiving PD. A total of 49 patients undergoing PD therapy were allocated to either the diabetic or the nondiabetic group. Salivary pH, dry mouth, taste change, and mucosal ulceration were determined for both groups. Salivary flow rate and pH were both lower in the diabetic group. Buffer capacity, dry mouth, taste change, and mucosal ulceration were all increased in that group. These findings were associated with level of glycosylated hemoglobin A1c. Our observations indicate that, compared with nondiabetic PD patients, patients with diabetes exhibit more severe oral uremic symptoms, including dry mouth, burning mouth syndrome, taste change, and mucosal ulcerations. The oral health in these patients should be followed.

    HYDROGENATION OF ACETOPHENONE AND ITS DERIVATIVES WITH 2-PROPANOL USING AMINOMETHYLPHOSPHINE-RUTHENIUM CATALYSIS
    (Taylor & Francis Ltd, 2010) Keles, Mustafa; Keles, Tugba; Serindag, Osman; Yasar, Sedat; Ozdemir, Ismail
    The reaction of 3'-aminopropyltriethoxysilane with the phosphonium salt ([Ph2P(CH2OH)(2)]Cl) gives an aminomethylphosphine-type ligand ((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2)). Reaction of the ligand ((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2)) with silica gives silica supported aminomethylphosphine ligand (SiO2)-O-Si(CH2)(3)N(CH2PPh2)(2)). The ligands were refluxed with [RuCl2(p-cymene)](2) in toluene to give [RuCl2((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2))] and silica-supported SiO2)-O-[RuCl2((Si(CH2)(3)N(CH2PPh2)(2))(2)] complex, respectively. The catalytic studies show that the complexes [RuCl2((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2))] and SiO2)-O-[RuCl2((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2))(2)] are very active catalysts for the transfer hydrogenation of acetophenone by 2-propanol in basic media. The best yield was observed in hydrogenation of m-methoxy acetophenone (95%) with catalyst [RuCl2((CH3CH2O)(3)Si(CH2)(3)N(CH2PPh2)(2))].
