    Comparison of Biochemical Parameters and Volatile Compounds of Some Hybrid Tomato Varieties
    (ANKARA UNIV, FAC AGR, 2017) Kara, Meryem; Sahin, Huseyin; Dinc, Saliha; Yildiz, Oktay; Can, Zehra; Er, Fatih
    Evaluating morphological and quality parameters such as shape, colour, size and yield are all common practices when assessing the quality of fruit and vegetables. In recent times, however, consumer interest in foods with high levels of bioactive components, high mineral content and acceptable flavor has increased considerably. In order to make a contribution to the production of fruit and vegetables with excellent morphological properties and high levels of bioactive compounds, two different hybrid tomato varieties (Ege F1 and Alida F1) cultivated in Turkey were compared in terms of their biochemical parameters (phenolic compounds, ascorbic acid, ss-carotene, lycopene, minerals) and volatiles. While the Alida F1 was rated the highest for lycopene and mineral values, the Ege F1 was outstanding in terms of phenolic compounds and volatiles. Ascorbic acid content of both cultivars ranged from 7.13 to 11.94 mg 100 g(-1) fw. The quantity in the Ege hybrid was remarkable. Chlorogenic acid, caffeic acid, p-coumaric acid, rutin and trans ferulic acid were the main phenolic compounds in both cultivars. Potassium (K) (4.09%) was the most predominant mineral in both hybrid tomatoes. Hexenal had the highest concentration value among tested volatiles followed by 2-hexenal, (6-methyl)-trans-5-Hepten-2-one. Comparison of biochemical parameters and volatiles of both varieties will give breeders an opportunity to choose the desired traits of tomatoes to cultivate for both taste and nutritional value.

    THE EFFECT OF DIFFERENT MANURES AND SYNTHETIC FERTILIZER ON BIOCHEMICAL AND ANTIMICROBIAL PROPERTIES OF MENTHA PIPERITA L
    (WILEY, 2014) Ozbucak, Tugba Bayrak; Erturk, Omer; Yildiz, Oktay; Bayrak, Ali; Kara, Meryem; Sahin, Huseyin; Kiralan, Mustafa
    The study was designed to examine the effects of different manures (fish, pigeon and cow) and synthetic fertilizer (nitrogen) on some biochemical activities of Mentha piperita L. (mint, peppermint). Seventeen different phenolic constituents and 19 essential oils were determined in M. piperita samples. While caffeic, gallic, ferulic, protocatechuic, syringic, o-coumaric acids and rutin were detected as common phenolics; carvone, limonene and 1.8-cineol were identified as major essential oil components in all mints. Total phenolic compounds, ferric reducing antioxidant power and cupric (III) reducing capacity (CUPRAC) tests were used to evaluate antioxidant capacities of the mints. The highest total phenolic compound (4.8 mg gallic acid equivalents/100 g) and antioxidant capacity (971 mM Fe(II)/mg; 823 mM Trolox /100 g) were observed in mints fertilized with pigeon manure. Mint samples also had different antimicrobial activities against the studied microorganisms (eight bacteria and two fungi), especially Escherichia coli and Listeria monocytogenes.

    EVALUATION AND APPLICATION OF THE TTA-RAPID METHOD IN DOGS WITH CRANIAL CRUCIATE LIGAMENT RUPTURE
    (DE GRUYTER OPEN LTD, 2017) Arican, Mustafa; Parlak, Kurtulus; Sahin, Huseyin
    The objective of this study intended the application of the current technique of modified tibial tuberosity advancement (TTA)-rapid method in dogs with cranial cruciate ligament rupture (CrCL) and reports on the clinical outcome and complications. The study material consisted of 17 male dogs of different breeds between the ages of 2-8 years, average weight of 32 kg with a diagnosed unilateral CCL rupture. Hudson Visual Analog Scale (HVAS)-Walking Test Rating, Canine Brief Pain Inventory (CPBI)Pain Rating) were examined, and rupture of the CCL was diagnosed based on direct radiographic examination. The pre-operative evaluation of the implant to be used in TTA-Rapid technique was determined by measuring radiographic images of the CCL in dogs. Post-operative evaluation in the 1(st), 2(nd), and at 3 month was performed by radiographic examination, gait and pain tests. Major complications were recorded in 17.6% of the cases. Fourteen (82.4%) dogs had a good to excellent outcome 3 months after surgery. Lameness and pain assessment were performed up to 15 days prior to the operation and 1, 2, and 3 months after the TTA-Rapid technique procedure.
