    Aripiprozole-Induced Diplopia: A Case Report
    (Kure Iletisim Grubu A S, 2013) Atli, Abdullah; Selvi, Yavuz; Yildiz, Aydin; Kaya, Mehmet Cemal
    Diplopia is a condition that involves seeing double and impairs quality of life. Acute diplopia can be seen with some general medical drugs and psychotropic drugs. Aripiprazole is a new atypical antipsychotic agent; it has partial agonist activity at D2 and 5-HT1A receptors and antagonist activity at 5-HT2A receptors. This paper reports development of diplopia, a rare adverse effect of psychotropic drugs, in a 24 year old patient with schizophreniform disorder following use of oral aripiprazole. Clinicians should keep in mind that diplopia may occur with aripiprazole treatment.

    High-Performance Liquid Chromatography Analysis and Assessment of Benzoic Acid in Yogurt, Ayran, and Cheese in Turkey
    (Springer, 2012) Yildiz, Aydin; Erdogan, Sait; Saydut, Abdurrahman; Hamamci, Candan
    Among food sources, particular attention is paid to milk and dairy products, due to its nutritional importance. Benzoic acid is extensively used in the preservation of foods. A reliable method for the determination of benzoic acid in some dairy products, such as yogurt, ayran, and cheese using high-performance liquid chromatography and UV detection was validated. The peak of benzoic acid was measured at a wavelenght of 226 nm. Samples were purchased from supermarkets in Turkey in the period 2009-2010. All dairy product samples were produced from cow's milk. The levels of benzoic acid in cheese, yogurt, and ayran samples were in the range of 3.17 to 56.77 mg kg(-1), 8.94 to 28.30 mg kg(-1), and 1.54 to 16.57 mg L-1, respectively. The results show that benzoic acid widely occurs in milk products in Turkey at the low levels.
